You first want to get rid of 2, so you divide two on both sides canceling the two on the left and getting x-1=5. then you add 1 to both sides getting x=6. Hope this helps!

1) Distribute the 2 to x and -1. You get: 2x - 2 = 10

2) Add 2 to both sides of the equation. You get:
2x = 12

3 Divide both sides by 2.
You get: x = 6

Find the product of the monomial and the polynomial. 4a^2b^3*(9a^4b^2-4a^2+3)
Artemon [7]

Answer:

Step-by-step explanation:

4a² b³ * (9a⁴b² - 4a² + 3) = 4a²b³ * 9a⁴b² - 4a²b³*4a² + 4a²b³*3

                                        = 36a²⁺⁴ b³⁺²  -16a²⁺²b³ + 12a²b³

                                         = 36a⁶b⁵ - 16a⁴b³ + 12a²b³

Image a coordinate plane with points plotted at ordered pairs Q(-4,4) R(2,4) S(5,-3) T(2,-3) and U (-4,-3) what is the area of t
pogonyaev

In counterclockwise order that's


R(2,4), Q(-4,4), U(-4,3), T(2,-3), S(5,-3)


That's a trapezoid, height 7 upper base 6, lower base 9, so average base 15/2 and area 7(15)/2 = 105/2 = 52.5.


Answer: 52.5


The shoelace theorem gives the answer without thinking. We write the list on top of itself shifted and add up the cross produces:


R(2,4), Q(-4,4), U(-4,-3), T(2,-3), S(5,-3)

Q(-4,4), U(-4,-3), T(2,-3), S(5,-3), R(2,4),


A = \frac 1 2 | 2(4)-(4)(-4) + -4(-3)-(-4)(4) + -4(-3)- -3(2) + 2(-3)-(-3)(5) + 5(4)- -3(2)| = \frac{105}{2} \quad\checkmark

Plz help! Will mark brainliest :3
svet-max [94.6K]

So this is using slope-intercept form (y=mx+b)

m is slope and b is the y-intercept

Looking at the graph, the line goes through the y-axis at (0,-5) so -5 is your y-intercept.

The slope of the line can be determine by using "rise over run". Find two points on the graph (I used 0,-5 and 1, -2). Count up from -5 to -2 (you get 3), count over from 0 to 1 (you get 1). Rise over run means that the slope equals 3.

Now, you just have to plug the numbers in.

Slope = 3; y-intercept = -5

y = 3x -5

The answer is A.) Y= 3x - 5

Hope this helps. Lmk if you need any more help :)
