Add the like terms.

The like terms in this case are:

-4x^2 and -2x^2

This makes -6x^2

-3y and 5y

This makes 2y

-8 and 1

This makes -7

Your answer is (-6x^2+2y-7)

3/7 x =5/14<br> solve for X

Paul [167]

Answer:

$\frac{5}{6} = x$

Step-by-step explanation:

$\frac{3}{7}x = \frac{5}{14} \\ \\ \frac{5}{14} \div \frac{3}{7} = \frac{5}{14} \times \frac{7}{3} = \frac{35}{42} = \frac{5}{6}$

Use multiplication [inverse of division] to figure this out.

* 2⅓ = 7⁄3

I am joyous to assist you anytime.

PLEASE HELP! I know the top part I just need the bottom!

Zolol [24]

slope = (y2-y1)/(x2-x1)

= (70-52)/(8-1)

= 18/7

=2.6

point slope form

y-y1 = m(x-x1)

y-52 = 2.6(x-1)

distribute

y-52 = 2.6x-2.6

add 52 to each side

y = 2.6x+49.4

y = 2.6x +49

the initial temperature is 49.4 or about 49

and it increases about 2.6 degrees each week
