Step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

here m = - [tex]\frac{5}{8}[/tex] and (a, b) = (- 10, - 6), hence

y + 6 = - [tex]\frac{5}{8}[/tex](x + 10)

Answer: x = 8

Step-by-step explanation:

4x + 18  +  5x  =  90

9x + 18 = 90             Added like terms

9x = 72                    Subtracted 18 from both sides

x = 8                       Divided both sides by 9

BONUS: The sum of these two angles is 90°, which means these angle are complementary.

Final answer will be the choice which matches best with expression

[tex]\frac{x^2+4x-1}{x\left(x+2\right)}[/tex] or

[tex]\frac{x^2+4x-1}{x^2+2x}[/tex]

Step-by-step explanation:

Given expression is:

[tex]\frac{\left(x+5\right)}{\left(x+2\right)}-\frac{\left(x+1\right)}{\left(x^2+2x\right)}[/tex]

We begin by factoring denominators:

[tex]=\frac{\left(x+5\right)}{\left(x+2\right)}-\frac{\left(x+1\right)}{x\left(x+2\right)}[/tex]

Multiply and divide first term by (x) to make denominators equal.

[tex]=\frac{x\left(x+5\right)}{x\left(x+2\right)}-\frac{\left(x+1\right)}{x\left(x+2\right)}[/tex]

Since denominators are equal so we can combine numerators.

[tex]=\frac{x\left(x+5\right)-\left(x+1\right)}{x\left(x+2\right)}[/tex]

Now simplify

[tex]=\frac{x^2+5x-x-1}{x\left(x+2\right)}[/tex]

[tex]=\frac{x^2+4x-1}{x\left(x+2\right)}[/tex]

[tex]=\frac{x^2+4x-1}{x^2+2x}[/tex]

Hence final answer will be the choice which matches best with expression

[tex]\frac{x^2+4x-1}{x\left(x+2\right)}[/tex] or

[tex]\frac{x^2+4x-1}{x^2+2x}[/tex]

Answer:

Option A

Step-by-step explanation:

The given function is a linear function therefore rate of change of this function will be the slope of the given line.

Since this line passes through two points ( 0,1 ) and ( 0.5 0 )

the slope of the line = [tex]\frac{(y-y')}{(x-x')}[/tex]

                     slope   = [tex]\frac{(1-0)}{(0-0.5)}[/tex]

                                 = ( -2 )  

Therfore, Option A will be the answer.

The rate of change of function is,

m = - 2

We have to given that,

A function is shown in figure.

Since, The rate of change of linear function is slope of line.

Here, Two points on the line are (1, - 1) and (0, 1)

Since, The equation of line passes through the points (1, - 1) and (0, 1)

So, We need to find the slope of the line.

Hence, Slope of the line is,

m = (y₂ - y₁) / (x₂ - x₁)

m = (1 - (-1)) / (0 - 1)

m = 2 / - 1

m = - 2

So, The rate of change of function is,

m = - 2

Given the dimensions of the brick, we first calculated its volume in cubic meters. Then we calculated the volume of the wall in cubic meters. Dividing the volume of the wall by the volume of a single brick, we find that we need 20,000 bricks to build the wall.

This is a problem in Mathematics, specifically involving volume and unit conversion. The volume of the brick can be calculated using the formula for the volume of a rectangular prism, Volume = length x width x height. The dimensions given for the brick are in centimeters and the wall dimensions are given in meters. Therefore, we must convert the brick dimensions to meters: 30 cm = 0.3 m, 10 cm = 0.1 m and 7.5 cm = 0.075 m. The volume of one brick is 0.3 m * 0.1 m * 0.075 m = 0.00225 cubic meters.

The volume of the wall is also given by the formula length x width x height, so it is 30 m * 2 m * 0.75 m = 45 cubic meters. To find the number of bricks required to fill this volume, divide the volume of the wall by the volume of a single brick, 45 m³ / 0.00225 m³ = 20000 bricks. Thus, it will take 20,000 bricks to build the wall.

Answer:

11.375 pounds

Step-by-step explanation:

1.75 * 6.5 = 11.375

11 and 3/8 pounds of meat are required in total.

The student is asking a multiplication problem that involves fractions. To find the amount of meat needed, we multiply the amount of meat required for one batch by the number of batches.

Step-by-Step Calculation

First, we must convert the fractions into improper fractions to simplify calculation. The recipe requires 1 and 3/4 pounds of meat, which is
7/4 pounds (since 1 pound is 4/4 pounds, we add 3/4 pounds to get 7/4 pounds).

Next, the number of batches is 6 and 1/2, which as an improper fraction is 13/2 batches.

To find the total amount of meat required, we multiply the pounds per batch by the number of batches: (7/4) pounds x (13/2) batches = (7/4) x (13/2) = (7 x 13) / (4 x 2) = 91/8 pounds.

Finally, convert 91/8 pounds to a mixed number: 11 and 3/8 pounds of meat are required in total.

Answer:

37 is your answer

Step-by-step explanation:

let "a number" = x

"twelve subtracted from [x]" = x - 12

"equals 25" = = 25

Set the equation

x - 12 = 25

Isolate the variable. Note the equal sign, what you do to one side, you do to the other. Add 12 to both sides

x - 12 (+12) = 25 (+12)

x = 25 + 12

x = 37

37 is your answer

~

The question is asking for a number that results in 25 when 12 is subtracted from it. This is an algebraic expression represented as x - 12 = 25. The solution is x = 37.

The question is asking to find a number when 12 is subtracted from it; the result is equals to 25. This is a basic algebraic expression where we let the unknown number be represented by the letter 'x'.

So, we can rewrite the question as an equation: x - 12 = 25.

To find 'x', we need to isolate it on one side of the equation, and to do so, we add 12 to both sides of the equation. This gives us: x = 25 + 12.

Adding 25 and 12, we get 37. So, the number you're looking for is 37.

Answer:

I think what you should do is 2/3 + 3/5 and then sutract it from the 2-ounce tube or you can do 2/15 - 2-ounces.

Step-by-step explanation:

Shelby used [tex]\frac{9}{15}[/tex]  or [tex]\frac{3}{5}[/tex]  ounce to paint the flag.

To determine how much paint Shelby used to paint her flag then, we have:

= [tex]\frac{2}{3}[/tex] + [tex]\frac{3}{5}[/tex] + [tex]\frac{2}{15}[/tex]   (let solve the first 2 fractions)

= [tex]\frac{2}{3}[/tex] + [tex]\frac{3}{5}[/tex] (the lowest common denominator of 3 and 5 is 15)

= (5 x 2) + (3 x 3) / 15

= (10) + (9) / 15

= 10 + 9 / 15

= [tex]\frac{19}{15}[/tex]  .

Now we should add [tex]\frac{9}{15}[/tex]  with the fraction of ounce she had left: [tex]\frac{2}{15}[/tex]

Therefore, we have  

= [tex]\frac{19}{15}[/tex] + [tex]\frac{2}{15}[/tex]  (the lowest denominator of 15 and 15 is 15)

= (19 x 1) + (1 x 2) / 15

= (19) + (2) / 15

= [tex]\frac{21}{15}[/tex]  .

Recall that the total paint is 2-ounce. Therefore, to get the fraction of ounce used to paint a flag, we have to subtract the ounce of the total paint from the [tex]\frac{21}{15}[/tex] .

Therefore we have:

2-[tex]\frac{21}{15}[/tex]  (can also be expressed as [tex]\frac{2}{1}[/tex] – [tex]\frac{21}{15}[/tex] )  

= (15 x 2) – (1 x 21) / 15 (the lowest denominator is 15)

= (30) – (21) / 15

= 30 – 21 / 15

= [tex]\frac{9}{15}[/tex]  or [tex]\frac{3}{15}[/tex]  .  

Therefore Shelby used [tex]\frac{9}{15}[/tex] or [tex]\frac{3}{5}[/tex] ounce to paint the flag.

The number [tex]\sqrt{24}[/tex] has a square [tex](\sqrt{24})^2=24.[/tex]

Since [tex]16<24<25,[/tex] you can conclude that

[tex]4<\sqrt{24}<5.[/tex]

Thus, two consecutive whole numbers that [tex]\sqrt{24}[/tex] lies between are 4 and 5.

Final answer:

√24 lies between the consecutive whole numbers 4 and 5 because 4² is 16 and 5² is 25, and 24 is between these two perfect squares.

Explanation:

To find two consecutive whole numbers that √24 lies between, we should first identify the perfect squares that are closest to 24 but less than and greater than 24.

The perfect square less than 24 is 4², which is 16, and the perfect square greater than 24 is 5², which is 25. Since √24 is greater than √16 (which is 4) and less than √25 (which is 5), √24 lies between the whole numbers 4 and 5.

Answer: Cube A is larger. This is because volume is found by multiplying length × width × height. The length, width, and height of a cube are ALWAYS equal. Therefore if cube B has a length of 4.8 inches it also has a height of 4.8 inches and a width of 4.8 inches. To find its volume multiply 4.8×4.8×4.8 this will give you 110.592 cubic inches. This means cube A is larger.

Cube A is bigger because of bigger volume.

Volume of cube A = 125 cubic inches

It says to use the point and slope from given equation to create the graph.

So compare equation y+6=45(x+3) with point slope formula

y-y1=m(x-x1)

we see that m=45, x1=-3 and y1=-6

Hence first point is at (-3,-6)

slope m=45 is positive so to find another point, previous point will move 45 units up then 1 unit right and reach at the location (-2,39).

Answer:

55 degrees

Step-by-step explanation:

Given that a circle and inside two chords with same arc length.

We are to find the angle between the two chords.

Given that two arcs subtend angle 125 degrees at the centre.

Let us join the two ends of chords to make the figure as a triangle inside a circle.

The triangle is isosceles as two arcs and hence chords are equal.

By central angle theorem we have the two equal angles as 1/2 (125) = 62.5

Hence we have a triangle with two equal angles 62.5 and another angle 1.

By triangle sum of angles theorem

angle 1+62.5+62.5 = 180

Hence angle A = 180-62.5-62.5 = 55 degrees.

If choice A says the two functions intersect at x = -2, then it would be the correct answer. Though it seems the "x=" part is left off. I'm not sure if this is intentional, or a typo.

The correct option is A) f and g intersect at x = -2

Step-by-step explanation:

Given :

x = -2 is a solution to the equation f(x) = g(x).

Solution :

x = -2 must be an intersection point of the equations f(x) and g(x) because

f(x) = g(x). And the point x = -2 satisfy both the equations.

Therefore, the correct option is A) f and g intersect at x = -2.

Final answer:

The new function after applying the given transformations to the linear parent function f(x) = x, results in f(x) = -1/4x, representing a combined vertical compression and reflection about the y-axis.

Explanation:

Starting with the linear parent function f(x) = x, we need to apply two transformations: a vertical compression by 1/4 and then a reflection over the y-axis. Applying a vertical compression by 1/4 means we multiply the output by 1/4, resulting in f(x) = (1/4)x.

To reflect the function across the y-axis, we replace x with -x, which gives us the new function f(x) = (1/4)(-x) or, simplified, f(x) = -1/4x. Therefore, the equation of the transformed function is f(x) = -1/4x.
