Answer 1
Answer:

A slope is also known as the gradient of a line. The slope of the given equation is -5/4.

What is a Slope?

A slope also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

slope = (y₂-y₁)/(x₂-x₁)

The given line passes through two points (0,2) and (-4,7), therefore, the slope of the given line can be written as,

Slope, m = (7 - 2)/(-4 - 0) = 5/-4

Hence, the slope of the given equation is -5/4.

A plumber has 8 9/10 feet of rubber tubing to make 2 rubber pipes. He will use3 1/12 feet of tubing to make each pipe. The plumber says he will have about 3 feet of rubber tubing after he makes the pipes. Is his statement reasonable?

Answers

Answer:the answer is D

Step-by-step explanation:

This is reasonable because  feet can be rounded to 9 feet and  feet can be rounded to 3 feet. Since 9 - 2(3) = 3, the plumber will have about 3 feet of rubber tubing left. its true make sure you read the answer to make sure bc they can mix them up LOL

What is 312% of 10.5 ?

Answers

312 % of 10.5=(312 / 100) (10.5)=(312*10.5) / 100=3276/100=32.76

or:

312% of 10.5=3.12 (10.5)=32.76

Answer: 312% of 10.5 is 32.76.

b. y = 30x + 1.25; $43.75
c. y = 30x + 1.25; $91.25
d. y = 1.25x + 30; $31.25

Answers

y = 1.25x + 30....after 3 hrs
y = 1.25(3) + 30
y = 3.75 + 30
y = 33.75

The variables x and y vary inversely. Use the given values to write an equation relating x and y. x=7/2 y=3/5

Answers

Answer:

x = 21/10y

Step-by-step explanation:

If the variables x and y vary inversely, this is expressed as;

x ∝ 1/y

x = k/y

k is the constant of proportionality

Given;

x = 7/2 and y = 3/5

Substitute;

7/2 =k/(3/5)

Cross multiply

k = 7/2 * 3/5

k = 21/10

Substitute the value of k into the formula;

x = k/y

x = (21/10)/y

x = 21/10 * 1/y

x = 21/10y

Hence the equation relating x and y is x = 21/10y

A soccer player kicks the ball down the field to a teammate. The height of the soccer ball above the ground, h, in relation to the time in seconds, t, is represented by the quadratic function shown in the table.Time (seconds) Height (feet)
0 0
0.5 12
1 16
1.5 12
Use the table to complete the statements.

The height of the soccer ball above the ground is symmetric about the line t =
second(s).

The ball landed on the ground at t =
second(s).

Answers

you can see that the height is the same at 0.5sec and 1.5 sec (12ft)

so therefore the height is symmetric about the line t=(midpoint of 0.5 and 1.5)

(0.5+1.5)/2=2/2=1

so the height is symmetric about the line t=1


the ball lands on the ground when height=0

since it is symmetric about t=1, and at t=0, the height is 0

1-0=1, so the difference between symmetry and desired height is 1

we must go in the oposite direction to find the next 0 height

so from symmetry to 0 height is 1+1=2, so at t=2 seconds
