Answer:

1- distributive property

2- Subtraction.

3- -3/2

Step-by-step explanation:

1- When the given equation is given, the 4 outside the parenthesis multiplied with the variable x and number 1. This process of multiplication between a number and all the variables in parenthesis is called known as the distributive property.

2- As it was adding with 2x on the left side when it passed with Inverse Operation to the right side, its sign change to subtraction.

3- The 2 passes to the other side of the equation with Inverse Operation, therefore dividing. The -3, otherwise, as it didn't move to the other side, has no effect and remains the negative.

Use slope-intercept form, y = mx + b to find the equation of the line that passes through the points (−6, 1) and (3, 4).

Nitella [24]

Answer:

Step-by-step explanation:

To solve this problem, first, you have to use the slope formula of y₂-y₁/x₂-x₁=rise/run. Remember to solve this problem, use slope-intercept form of y=mx+b.

m represents the slope.

b represents the y-intercept.

Y₂=4

Y₁=1

X₂=3

X₁=(-6)

Solve & simplify.

$\displaystyle \mathsf{\frac{4-1}{3-(-6)}=\frac{3}{9}=\frac{3\div3}{9\div3}=\frac{1}{3} }}$

The slope is 1/3.

Y-intercept is 3.

y=1/3x+3

In conclusion, the correct answer is y=1/3x+3.

Answer:

The gear ratio is calculated by dividing the output speed by the input speed (i= Ws/ We) or by dividing the number of teeth of the driving gear by the number of teeth of the driven gear (i= Ze/ Zs)

A study showed that the ratio of the number of people who get their news from social media to the number of people who their new

zhenek [66]

Answer: 270 people

Step-by-step explanation:

The ratio of the number of people who get their news from social media to the number of people who their news from other sources is 3 to 7.

This shows that the number of people who get their news from social media is 3 out of 10 i.e (3+7).

Therefore, the number of people in a town of 900 people that get their news from social media will be:

= 3/10 × 900

= 270 people.
