Answer:

y = 6/5 x-1  slope intercept form

6x-5y = 5  standard form

Step-by-step explanation:

We have the points  (0,-1) and (-5,-7)

We can find the slope using

m = (y2-y1)/(x2-x1)

 = (-7--1)/(-5-0)

 = (-7+1)/(-5-0)

 = -6/-5

 = 6/5

We also have the y intercept ( when x=0)  It is -1

We can use the slope intercept form of the equation y = mx+b

y = 6/5 x-1

Depending on what you mean when you say simplify your answer

We can put it in standard form  ax+by = C

Multiply both sides by 5

5y =5* 6/5 x-1*5

5y = 6x-5

Subtract 6x from each side

-6x+5y = 6x-6x-5

-6x+5y = -5

Multiply by -1

6x-5y = 5

The number of tunnels is 3 more than twice the number of bridges. How many bridges, b, are there in Chestnutville, and how many tunnels, t, are there in Chestnutville?

Answer:

5 mililmiters = 0,005 meters = 0,000005 kilometers

2 kilometers = 2000 meters

Step-by-step explanation:

km  / hectometer / decameter / meter / dcm / centimeter / milimeter

1000 m /     100  m   /    10   m     <     1  >    0,1 m/    0,01  m     /  0,0001 m

1 meter = 0,  1 decimeters / 0, 01 centimeters /0, 000 1 millimeters

1 meter = 10 decameters / 100 hectometers / 1000 kilometers

so 5 millimeters = 0,005 meters = 0, 000 005 kilometers

so  2 km = 2 000 meters  = 2 000 000 millimeters

the reference unit of measure is the meter.

Answer:

Function 2 has a greater rate of change

Step-by-step explanation:

Function 1:

Number of Weeks (x)               1     2      3     4

Amount Remaining (dollars) (y) 40   36    32   28

We can find the slope by using

m = (y2-y1)/ (x2-x1)

  = (40-36)/ (1-2)

  = 4/-1

 = -4

Function 2:

y = −5x + 40

Using y = mx+b

The slope is -5

Function 2 has a greater rate of change

Answer:

Density = 1.042  grams /cm^3

Step-by-step explanation:

Work out the mass of each of three in a unit volume (cm^3)

Givens

Mixture

35 cm^3 Apple Juice = 1.04 grams / cm^3 * 35 cm^3 = 36.4 grams

25 cm^3 Fruit = 1.6 grams/cm^3 * 25 cm^3 =                  40    grams

270 cm^3 water = 0.99 * 270                                        267.3 grams

Total Mixture

Density

Density = mass / volume = 343.7 / 330 = 1.0415

Answer

1.042 grams / cm^3  

The density of the resulting drink is; 1.042 grams per cm³.

To find the density of the resulting drink, we need to first determine the mass of each of the constituents.

The masses of the constituents can be found as follows;

For apple juice;

For fruit syrup;

For sparkling water;

Therefore, the total mass of the drink is;

And, since the total volume of the drink is 330cm³

Density of the drink = 1.042 grams per cm³.

Answer:

Step-by-step explanation:

You have to distinguish the difference between a ratio of yellow bulb to red bulb and red bulb to total and yellow bulb to total. The totals are where you start.

2 bulbs out of 5 are yellow

3 bulbs out of 5 are red

Yellow

Set up the proportion for yellow. You could start with red.

Red

Note: Yellow to red is 2/3            

When multiplying the same base with exponents, you keep the base the same and then you add the exponents, so for this question you do:

Answer:

b. 3 4/6 cant equal 3 2/3

Step-by-step explanation:

Substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12    use distributive property

x + (2)(2x) + (2)(-4) = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20    divide both sides by 5

x = 4

Put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4

Answer:

x=4, y=4

Step-by-step explanation:

y=2x-4;

x+2y=12

We can use substitution since the first equation is solved for y

Where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

Distribute the 2

x+4x-8 = 12

Combine like terms

5x-8=12

Add 8 to each side

5x-8+8=12+8

5x=20

Divide by 5

5x/5 = 20/5

x =4

We still need to solve for y

y = 2x-4

We know x =4

y = 2(4) -4

y = 8-4

y=4

Equation : (1/2)n + n = 90

Apples picked up by Nate : 60

Apples picked up Laura : = 30

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Nate and Laura picked apples. Laura picked 1/2 as many as Nate picked. Together they picked 90 apples.

Let [n] stand for the number Nate picked. Then, the number of apples picked up by Laura will be (1/2)n. Then, we can write -

Equation : (1/2)n + n = 90

1.5n = 90

n = (90/1.5)

n = 60

Apples picked up by Nate : 60

Apples picked up Laura : 60/2 = 30

Therefore, the answers to all the parts are -

Equation : (1/2)n + n = 90

Apples picked up by Nate : 60

Apples picked up Laura : = 30

Answer:

50 C = 122 F

Step-by-step explanation:

50°C × 9/5 +32

Answer:

50°C = 122°F.

Step-by-step explanation:

Given  : The formula to convert F° to C° is [tex]C = \frac{5}{9}( f - 32)[/tex].

To find :  Convert 50°C to °F

Solution : We have given

[tex]C = \frac{5}{9}( f - 32)[/tex].

On multiplying by 9 both sides.

[tex]9 C = 5( f - 32)[/tex].

On dividing both sides by 5

[tex]\frac{9C}{5} =( f - 32)[/tex].

On adding both sides by 32

[tex]\frac{9C}{5}+ 32 = f[/tex].

Then plug C = 50°

[tex]\frac{9 * 50 }{5}+ 32 = f[/tex].

[tex]\frac{450}{5}+ 32 = f[/tex].

[tex] 90+ 32 = f[/tex].

[tex] 122°= f[/tex].

Therefore,  50°C = 122°F.

Answer:b = (2A - hB)/h

Step-by-step explanation:

See , we know area of a trapezoid is equal to 1/2*(sum of parallel sides)* perpendicular distance between parallel sides.

Here B and b are parallel sides which we know by comparing the equation.

And 'h' here is the perpendicular distance between parallel sides.

We have to write the equation in terms of one of the parallel sides 'b'

Our formula is A = 1/2*h*(B+b)

I.e. 2A = h*(B+b) (Multiplying both sides by 2)

I.e. 2A - hB = hb

I.e. b = (2A - hB)/h

Answer:

y = 0 and z = 5

Step-by-step explanation:

the denominator of the expression cannot equal zero as this would make the expression undefined Equating the denominator to zero and solving gives the values that y and z cannot be

solve y(z - 5) = 0

equate each factor to zero and solve

The factored equivalent expression for 12z+36 is 12(z + 3) after factoring out the common factor of 12.

When asked to write all factored equivalent expressions for 12z+36, we look for common factors. Both terms have a common factor of 12. Factoring out the 12, we get 12(z + 3). There are no other common factors, and the expression cannot be factored further as both terms within the parentheses are prime with respect to each other.
