What is an equation of the line in slope intercept form? m = 4 and the y-intercept is (0, 5) (1 point)?
Answer:
[tex]y=4x+5[/tex]
Step-by-step explanation:
Mathematically, the slope m of a line is:
[tex]m=\frac{\Delta y}{\Delta x} = \frac{y-y_o}{x-x_o}[/tex]
Therefore, if we know the slope m of the line and a point [tex](x_o , y_o)[/tex] we will be able to find its equation simply solving for y:
[tex]y-y_o=m(x-x_o)[/tex]
Replacing the data provided by the problem:
[tex]y-5=4(x-0)\\\\y-5=4x\\\\y=4x+5[/tex]
jasmine has $15 dollars and save $2.50 every month . radha has $0 and save $3.50 every month. jasmines savings after x months can be represented by the function f(x)=2.5x+15. radahs savings after x months can be represented by the function g(x)=3.5x after how any moths will they both have the same amount in savings? find the value of x which f(x)=g(x)
2.5x+15 = 3.5x
subtract 2.5x from each side
15 = x
they will have the same amount after 15 months

Write the solution to the given inequality in interval notation.
[-3,-1)
(-3,-1]
(-∞,-3) U [-1,∞)
(-∞,-3] U (-1,∞)
Answer:
D. [tex](-\infty,-3]\text{U}(-1,\infty)[/tex]
Step-by-step explanation:
We have been given solution of an inequality on number line. We are asked to write the solution to the given inequality in interval notation.
We can see that all values of x less than or equal [tex]-3[/tex] and greater than [tex]-1[/tex] are solution for our given inequality.
We have a solid dot at [tex]-3[/tex], so [tex]-3[/tex] is a solution of inequality.
We have a open dot at [tex]-1[/tex], so [tex]-1[/tex] is not a solution of inequality.
Upon combining both solutions, we will get:
[tex](-\infty,-3]\text{U}(-1,\infty)[/tex]
Therefore, the solution for the inequality is [tex](-\infty,-3]\text{U}(-1,\infty)[/tex].
Anna has 10 to the 2nd power quarters. Jazmin has 10 to the second power dimes Who has more money, Anna or Jasmine? How much more? Explain
This question is based on the concept of logical reasoning.Therefore,they both have the same amounts of coins, the one with 100 quarters has more money.Thus, Anna has more money than Jasmine.
Given:
Anna has 10 to the 2nd power quarters. Jazmin has 10 to the second power dimes.
We need to calculate the who has more money, Anna or Jasmine.
According to the question,
Anna has 10 to the 2nd power quarters.
In mathematically expressed as,
[tex]\bold{10^2 = 100}[/tex] quarters
Now, Jazmin has 10 to the second power dimes.
In mathematically expressed as,
[tex]\bold{10^2 = 100}[/tex] dimes
So,they both have 100 coins. But, we know that quarter is 25 cents, while a dime is only 10 cents.
Anna has 100 quarters = [tex]\bold{100 \times 25 = 2500}[/tex]. That is 25 dollars.
Jasmine has 100 dimes = [tex]\bold{100 \times 10 = 1000}[/tex]. This is 10 dollars.
Therefore,they both have the same amounts of coins, the one with 100 quarters has more money.Thus, Anna has more money than Jasmine.

A rectangle has one side on the xx-axis and two vertices on the curve y=74+x2. y=74+x2. find the vertices of the rectangle with maximum area.
The rectangle with maximum area does not exist as the curve y = 74 + x^2 does not intersect the x-axis.
Explanation:To find the vertices of the rectangle with maximum area, we need to find the points of intersection between the curve y = 74 + x^2 and the x-axis.
Setting y = 0, we can solve the equation 74 + x^2 = 0 to find the x-coordinates of the vertices.
Since the curve is a parabola facing upwards, there are no points of intersection with the x-axis.
Therefore, the rectangle does not exist.

You have a rectangular vegetable garden in your backyard that measures 15 feet by 10 feet. You want to double the area of the garden by adding the same distance x to the length and width of the garden. Find the value of x and the new dimensions of the garden.
To double the area of the rectangular vegetable garden, we need to add the same distance, x, to the length and width. The value of x is 10 feet, and the new dimensions of the garden are 25 feet by 20 feet.
Explanation:To double the area of the garden, we need to add the same distance, x, to both the length and width of the garden. The original dimensions of the garden are 15 feet by 10 feet, with an area of 150 square feet. To double the area, we set up the equation 2(15+x)(10+x) = 2(15)(10). Solving this equation gives us the value of x and the new dimensions of the garden.
Expanding the equation, we have 30x + x² + 300 = 300. This simplifies to x² + 30x - 300 = 0. Factoring this quadratic equation, we get (x - 10)(x + 30) = 0. So x = -30 or x = 10. We discard the negative value since distance cannot be negative, so x = 10 feet.
The new dimensions of the garden are 15+10 = 25 feet and 10+10 = 20 feet.

Kendall is stacking boxes that are 7.5inches tall. Explain how to find the height (in inches)
Final answer:
To find the height of stacked boxes, multiply the height of one box (7.5 inches) by the total number of boxes stacked.
Explanation:
Kendall is stacking boxes that are each 7.5 inches tall. To find the total height in inches of the stacked boxes, you would need to multiply the height of one box by the total number of boxes stacked. For example, if Kendall stacks 10 boxes, the calculation would be 7.5 inches x 10, which equals 75 inches. Therefore, the total height of the 10 stacked boxes would be 75 inches.

Given: M is the midpoint of LN; LM =8 prove:LN=16
The proof of LN= 16 is shown below:
What is midpoint?The midpoint formula is applied when one is required to find the exact center point between two defined points. So for a line segment, use this formula to calculate the point that bisects a line segment defined by the two points.
Given:
LM= 8
and M is the midpoint of LN
So, the line LN will be break into two equal parts LM and MN
then we can write
LM= MN= 8

The area of a rectangular piece of sheet metal is 216 ft. the width of the sheet is 6 ft less than the length what are the dimensions of th epiece of metal
Using algebra, the dimensions of the rectangular sheet metal with an area of 216 sq ft and width being 6 ft less than the length are found to be 18 ft by 12 ft.
The area of a rectangular piece of sheet metal is given as 216 square feet, and the width is stated to be 6 feet less than the length. Use algebra to find the length (l) and the width (w) of the sheet. Since the width is 6 ft less than the length, we can express this relationship as: w=l- 6.
The area of a rectangle is calculated by the formula Area = length imes width, so we can set up the equation 216 = l imes (l - 6). Solving the quadratic equation l^2 - 6l - 216 = 0 we find that the possible values for l are 18 ft (acceptable since length is positive) and -12 ft (which is not physically meaningful for this context), leaving us with the length of the piece of metal being 18 feet. Consequently, the width would be l - 6, which is 18 - 6 = 12 ft.
Therefore, the dimensions of the piece of metal are 18 feet in length and 12 feet in width.

Of the birds in Monica's pet shop, 1/5 are pigeons. Of the pigeons, 1/3 are white. Look at each expression. Can it be used to find the fraction of birds in Monica's pet shop that are white pigeons?
1/15.
The expression that can be used to find the fraction of birds in Monica's pet shop that are white pigeons is:
1/5 x 1/3 = 1/15
This calculation is derived by multiplying the fraction of pigeons in the pet shop (1/5) by the fraction of white pigeons among pigeons (1/3).
