Which pair shows equivalent expressions? PLEASE HURRY IM BEING TIMED!!!!

Answer:

[tex]y = - 2x + 7[/tex]

you can see from graph that line is going through (0,7) and (5,-3) and that is enough to fine the equation of a line using formula

[tex]y-y_1= \frac{y_2-y_1}{x_2-x_1} \times (x-x_1)[/tex]

Step-by-step explanation:

A + B = 0

A = -B

(-B)B) = -36

-B^2 = -36

B^2 = 36

B = 6, -6

So, A = -6, 6

A - B = -12

or

A - B = 12

Answer:

A - B = ± 12

Step-by-step explanation:

Given

A + B = 0  → (1)

AB = - 36 → (2)

Subtract B from both sides of (1)

A = - B ← substitute into (2)

- B(B) = - 36 ( multiply both sides by 0 1 )

B² = 36 ( take square root of both sides )

B = ± 6

Substitute into (1)

If B = 6 then A =- 6 and A-B = - 6 - 6 = - 12

If B = - 6 then A = 6 and A - B = 6 - (- 6) = 6 + 6 = 12

Answer:

B.the conductor

Step-by-step explanation:

Answer:  y = -320

Steps:  ³⁄₂y + 12 = ⁷⁄₅y - 20

Subtract 12 from both sides:  ³⁄₂y + 12 - 12 = ⁷⁄₅y - 20 - 12

Simplify: ³⁄₂y = ⁷⁄₅y -32

Subtract ⁷⁄₅y from both sides: ³⁄₂y -  ⁷⁄₅y = ⁷⁄₅y -32 -  ⁷⁄₅y

Simplify: ⅒y = -32

Multiply both sides by ten: 10  ·  ⅒y = 10  · -32

Simplify: y = -320

Answer:

1071/112=1%

1%= 9.5625

100%= 9.5625*100 = 956.25

Example:

112 People attendet this year. If the increase Was also 12%, a 112 people equals 112%. So,

112/112=1

1*100= 100

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The toy rocket is launched from a platform

The height of the platform = 12 feet

The initial velocity of the rocket = 128 feet / second

Let the height of the launch be = h

Let the time taken by the rocket be = t

The height after the launch after t seconds is given by the equation

h ( t ) = -16t² + 128t + 12

Now , for the rocket to reach the ground , the equation will be

h ( t ) = -16t² + 128t

Since , it is launched from the 12 foot platform , the equation will be

h ( t ) = -16t² + 128t

The height of the rocket on reaching the ground h ( t ) = 0

Substituting the value of h ( t ) in the equation , we get

h ( t ) = -16t² + 128t

0 = -16t² + 128t

16t² - 128t = 0

16t ( t - 8 ) = 0

t - 8 = 0

Adding 8 on both sides , we get

t = 8 seconds

Hence , the time taken by the rocket to reach the ground is 8 seconds

Answer:

11 ; C

Step-by-step explanation:

To get the class width, we start by finding the range of the data set

That will be; the highest number - the smallest number

= 87-2 = 85

We proceed by dividing the number of classes we want by this number

That will be 85/8 = 10.625

We now proceed to approximate this value to the nearest whole number = 11

Hence , 11 is the class width to use

Answer:

Step-by-step explanation:

These are what the symbols mean so you can better understand them

p: I like to go to the beach

q: I like to eat ice cream

r: I do not enjoy rainy days

^ = means OR so a that has or in it.

v = means AND so any sentance with and in it

~ = not so any phrase that condridicts what the origional P,Q, and/or R

∴ = Therefore so any phrase with therefore.

So; p ∧ q would be P... OR... Q  acording to the key above would be

I ilke to go to the beach OR I like to eat icecream.
