Answer:

1) 0.75

2) y = [tex]\frac{3}{4}[/tex]x - 3

3) (4, 0); (0, -3)

Step-by-step explanation:

Convert to slope-intercept form (y = mx + b) by solving:

y = [tex]\frac{3}{4}[/tex]x - 3

m is the slope, so [tex]\frac{3}{4}[/tex] or you can write as 0.75.

To find the x and y intercepts, set the y value to zero and solve (x-intercept), and b is the y-intercept.

A large can of soup contains 19 fl oz A serving is about eight Oz How many Canz should you buy if you want to serve How many Cans should you buy if you want to serve 7 people

Answers

Answer:

2.95 cans of soup

Step-by-step explanation:

A large can of soup contains 19 fl oz A serving is about eight Oz How many Canz should you buy if you want to serve How many Cans should you buy if you want to serve 7 people

Step 1

From the above question:

1 serving = 1 Person

1 person = 8oz

7 persons = x

Cross Multiply

x = 7 × 8oz

x = 56 oz

Step 2

56 oz will serve 7 people

M

From the question also, we are told that:

19 oz = 1 can of soup

56 oz = x

Cross Multiply

19x = 56 × 1

x = 56 /19

x =2.9473684211 cans of soup

B. g(x) = -1/4x-1
O C. g(x) = -4x
O D. g(x) = 1/4x

Answers

Answer:

C

Step-by-step explanation:

A vertical stretch is accomplished by multiplying the parent by the stretch factor (given as 4 in this problem).  At that point, the function is

h(x) = 4x

To flip over the x-axis, change the sign of the function's rule.

g(x) = -4x

In the attached image, f(x) = x is purple, h(x) = 4x is black, g(x) = -4x is red.

x = 2
y = −0.75x + 9.5
y = 1.33x + 1.66
x = 8

Answers

Answer:

x=2

Step-by-step explanation:

got it right on the test i promise

The equation of the line that is tangent to circle A from point C (2, 8) is x = 2 option (A) x = 2 is correct.

What is a circle?

It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)

It is given that:

Circle A is located at (6, 5) and has a radius of 4 units.

First, find the slope of the radius

As we know, the ratio that y increase as x increases is the slope of a line. The slope of a line reflects how steep it is, but how much y increases as x increases. Anywhere on the line, the slope stays unchanged (the same).

[tex]\rm m =\dfrac{y_2-y_1}{x_2-x_1}[/tex]

The line passes through (2, 8) and (2, 5)

y - 5 = (-3/0)(x -2)

-x + 2 = 0

x = 2

Thus, the equation of the line that is tangent to circle A from point C (2, 8) is x = 2 option (A) x = 2 is correct.

the profit equation for a manufactioring company is p=x^2-2500 where p is profit, and x is number of units sold. For what number of units sold does the company break even? (p=0)

Answers

Answer:

For the company to break even, the number of units sold is 500 units

Step-by-step explanation:

To get this number of units, we simply substitute the value of 0 for p

we have this as;

0 =x^2 -2500

x^2 = 2500

x = √2500

x = 500 (we do not consider the other root of x = -500 since the number of quantities cannot be negative)

•Radius=5in height=4


V=60 in3


V=100/3 in3


V=32 in3

Answer:

Step-by-step explanation:

Match each cone’s measures to its corresponding volume.

The formula for the volume of a cone is given as:

πr²h/3

a) base area=16in² height=6in

Base area of a cone = πr²

Hence, volume of this cone = 16in² × 6 in

•Radius=5in height=4
