Key to this problem! Distribution!

-7x(11x+12)

Imagine -7x going to both 11x and 12. Meaning it would multiply with both those numbers. If helpful, write arrows that it goes to both numbers inside the parenthesis to help you out.

-7x(11x)+12(-7x)

-7 x 11 is -77, and x times x is x^2, so the first part would equal to -77x^2

12 x -7 is -84, and add a x to get -84x.

The final answer is -77x^2-84x

Answer/Step-by-step explanation:

✍️Slope of the line using two points, (2, 2) and (6, 10),

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{10 - 2}{6 - 2} = \frac{8}{4} = 2$

✍️To find the equation of the line in slope-intercept form, we need to find the y-intercept (b).

Substitute x = 2, y = 2, and m = 2 in y = mx + b, and solve for b.

2 = (2)(2) + b

2 = 4 + b

2 - 4 = b

-2 = b

b = -2

Substitute m = 2 and b = -2 in y = mx + b.

✅The equation would be:

$y = 2x + (-2)$

$y = 2x - 2$

✍️To find the value of a, plug in (a, 8) as (x, y) into the equation of the line.

$8 = 2(a) - 2$

$8 = 2a - 2$

Add 2 to both sides

$8 + 2 = 2a$

$10 = 2a$

Divide both sides by 2

$\frac{10}{2} = a$

$5 = a$

a = 5

✍️To find the value of b, plug in (4, b) as (x, y) into the equation of the line.

$b = 2(4) - 2$

$b = 8 - 2$

$b = 6$

3•f(-4)-3•g(-2)=?<br> Help please

Scilla [17]

Answer:

3⋅f(−4)−3⋅g(−2) = −12f+6g

Step-by-step explanation:

Write the problem as a mathematical expression.

3⋅f(−4)−3⋅g(−2)

Move − 4 to the left of f .

3⋅(−4⋅f)−3⋅(g(−2) )

Multiply−4 by 3.

−12f−3⋅(g(−2) )

Move − 2 to the left of g .

−12f−3⋅(−2⋅g)

and lastly Multiply−2 by −3.

−12f+6g

Hope this helps you out.
