The complete question in the attached figure

Let
w --------> represent the number of weeks that Jack saves
s --------- > represent the total amount saved, in dollars

step 1
find the equation of the line
points
(2,12) and (4,24)
slope m=(s2-s1)/(w2-w1)------->m=(24-12)/(4-2)-----> m=6

step 2
with m=6 and point (2,12)
s-s1=m*(w-w1)--------> s-12=6*(w-2)-----> s=6w-12+12-----> s=6w

the answer is
s=6w

Use mental math to find the equations that are true. Select all that apply. A. 400 ÷ 80 = 50 B. 4 , 000 ÷ 80 = 5 C. 400 ÷ 8 = 50

NeX [460]

As per the mental math calculation, the correct division equations are

C. 400 ÷ 8 = 50

D. 40,000 ÷ 800 = 50

E. 40,000 ÷ 80 = 50

Mental math calculation:

Mental math calculation means a group of skills that allow people to do math “in their head” without using pencil and paper or a calculator.

We can done any type of calculation like addition, subtraction, division etc. based on this method.

Given,

Here we have the following equations,

A. 400 ÷ 80 = 50

B. 4 , 000 ÷ 80 = 5

C. 400 ÷ 8 = 50

D. 40 , 000 ÷ 800 = 50

E. 40 , 000 ÷ 80 = 500

And we need to find the equations that are true by using the mental math calculation.

While we looking into the given expressions,

A. 400 ÷ 80 = 50

This one is false because when we cancel zero, and divide it we get 5 alone.

Then the next one is,

B. 4,000 ÷ 80 = 5

This one is false because when we cancel zero, and divide it we get 50 alone.

Third one is

C. 400 ÷ 8 = 50

This one is true because when we cancel zero, and divide it we get 50 as result.

Next is,

D. 40,000 ÷ 800 = 50

This one is true because when we cancel zero, and divide it we get 50 as result.

Final one,

D. 40,000 ÷ 80 = 500

This one is true because when we cancel zero, and divide it we get 500 as result.

Therefore, options C, D and E are true.

Use the distributive property -5 {x + 4} + -3x + -9x + -7

grin007 [14]

Answer:

-17x - 27

Step-by-step explanation:

Distributive property is the multiplication of the number outside the parenthesis and the ones inside.

-5(x + 4) + -3x + -9x + -7

-5x - 20 + -3x + -9x + -7

Combine like terms:

-5x - 20 + -3x + -9x + -7

-5x +-3x

-8x + -9x

-17x

-17x - 20 + -7

-20 + -7

-27

The answer is -17x - 27

Hope this helped.

Line AB is tangent to circle O at A. The diagram is not drawn to scale.

Arlecino [84]

AO = 21
BC = 14
OC = radius of the circle = AO = 21
∴ OB = OC + CB = 21 + 14 = 35
<span>Line AB is tangent to circle O at A</span>
∴ AB is perpendicular to AO
∴ Δ OAB is a right triangle at A
Applying Pythagorean theorem
∴ OB² = AO² + AB²
∴ AB² = OB² - AO² = 35² - 21² = 1225 - 441 = 784
∴ AB = √784 = 28

Lets hope i'm right.

Triangle formula: 1 / 2 b x h

Half one of them. Lets do 4 since 5 would result in a decimal.

(4) = 2 x 5 = 10.

y (10) + 1 = 11

Half one.

(2) = 1 x 3 = 3

Answers:

y = 11

x = 3

Hope this helps! Wait for another answer to make sure i'm right. ;) ~Pooch ♥
