That is the answer for solving for A

Answer:

The x-intercept is 4,0. The y-intercept is 0,2.

Step-by-step explanation:

when your finding an intercept you make the other intercept 0. This means the equation to find the x-intercept would look like 5x = 20. This is because they = 0, which means 10 x 0 is 0. Then you use the inverse operation so since it's 5 * x, it will be 20 ÷ 5 which is 4. Do the same thing with the y-intercept. Instead of changing the y to a 0, change the x. Using the inverse operation you get 2.

Answer:

-5/4

Step-by-step explanation:

The slope of a line y=4x-5 is 4.

The equation of a line is y=-5+4x.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The formula to find the slope of a line is slope = (y2-y1)/(x2-x1)

The standard form of equation of line is y=mx+c

m is a slope of a line and c is y-intercept

Compare the equation y=4x-5 with y=mx+c, we get m=4

Therefore, the slope of a line y=4x-5 is 4.

Answer:

0

Step-by-step explanation:

To find slope you need to take two points from the line and use the slope formula ([tex]m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}[/tex])

Im going to take the points (0,3) and (-2,3) So now lets put these coordinates into the formula:

this would give us 0

(Edit* tbh i think the line might not even exist - ya know it says ¨Find the slope of the line if it exists¨ anyway ~_~ hope this helped...!)

Answer:

Slope m=-5/3

Step-by-step explanation:

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

You need to use two points

(x1,y1)= (0,3)

(x2,y2)= (3,-2)

m=(-2-3)/(3-0) = -5/3

Answer:

The unit price is the cost per unit of an item or the cost/price for each item.

1) 4$ per pound. By simplifying the proportion (constant ratio) between the cost, and the pounds of apples. 3 pounds of apples cost 12$ → 3/3 pounds of apples cost 12/3$ → 4 dollars for every pound.

2) 2$ per pound. By evaluating the rate of change (change in the y over x or dependent variable over independent) in the equation: y = 2x. y is the cost in dollars, and x is the pounds of apples. So there are 2 pounds (weight) of apples for every dollar.

3) 3$ per pound. Given a graph with a y scaled by 3, and an x scaled by 1 with a graph y = x or 1 unit up for every unit right. This must be equivalent to y = 3x. Where y is labeled as the cost in dollars, and x as the weight in pounds. So there are 3 dollars for every pound of apples.

4) Store B. Because 2 is less than 3 which is less than 4.

Answer:

b

Step-by-step explanation:

f(x) = x³ + x² - 66x + 54

= (x² - 8x + 6)(x + 9) + 0

=> the answer is b

Answer:

b

Step-by-step explanation:

If (x + h) is a divisor of f(x) then f(- h) = remainder

If f(- h) = 0 then (x + h) is a factor of f(x)

Here divisor is (x + 9) , then

f(- 9) = (- 9)³ + (- 9)² - 66(- 9) + 54

        = - 729 + 81 + 594 + 54

        = 0

Thus remainder is 0 and (x + 9) is a factor of f(x)

Answer:

x≤−9 or x≥5 or x=0

Step-by-step explanation:

Let's solve your inequality step-by-step.

x2(x+9)(x−5)≥0

x4+4x3−45x2≥0

Let's find the critical points of the inequality.

x4+4x3−45x2=0

x2(x−5)(x+9)=0(Factor left side of equation)

x2=0 or x−5=0 or x+9=0(Set factors equal to 0)

x=0 or x=5 or x=−9

Check intervals in between critical points. (Test values in the intervals to see if they work.)

x≤−9(Works in original inequality)

−9≤x≤0(Doesn't work in original inequality)

0≤x≤5(Doesn't work in original inequality)

x≥5(Works in original inequality)

Answer:

x≤−9 or x≥5 or x=0

b. the graph of f(x) is a horizontal stretch of the graph of the parent function.

The True statement is

The graph of f(x) is a horizontal stretch of the graph of the parent function.

In mathematics, a function is an expression, rule, or law that establishes a relationship between an independent variable and a dependant one (the dependent variable).

We have,

f(x) = -2/3 |x+4| - 6

So, -2/3 |x+4| - 6 = 0

-2/3 |x+4| = 6

|x+4| = -9

so, the vertex is not (-4, 6).

Here the -6 in the function shows the horizontal stretch.

Answer: -4 is correct

Step-by-step explanation:

Answer:

y=7.5x, y=60

Step-by-step explanation:

you have to consider x as the input and y as output

when input  x=2 the output  y=15  so it grew by 7.5 so we can say that y= 2*7.5

in general the equation is y= 7.5*x

when x=8 we will have y=7.5*8=60
