Answer:

Remove parentheses.

−7x²−3x^{4}−5−3x^{4}+3+9x²

Add −7x² and 9x² .

2x²−3x^{4}−5−3x^{4}+3

Subtract 3x^{4} from −3x^{4}.

2x²−6x^{4}−5+3

Add −5 and 3.

2x²−6x^{4}−2

Find the least whole number that can replace blank 80 to make the statement true. ÷ 18 > 86
sweet-ann [11.9K]

Answer:

649

Step-by-step explanation:

Given the expression :

__ ÷ 18 > 86

Let blank = y

y ÷ 18 > 36

y / 18 > 36

Multiply both sides by 18

(y / 18) * 18 > 36 * 18

y > 648

Hence, the least whole number which can make the statement true is (648 + 1) = 649

Write the equation of the line with a slope of 2 that passes through the points -2 -7 and 5 7
Marat540 [252]
Hello!
Really, we could finish this problem without knowing the slope or just having one of the given points.
However, since they gave us the slope, let's take the easier way.

y = 2x + b
To find b, we can plug in one of the points. (it doesn't matter which)
7 = 2(5) + b
7 = 10 + b
b = 7-10 = -3

So, the final equation is y = 2x - 3 or answer choice D.

Hope this helps!! let me know if you have ANY questions.

Find rhe equation of the graphed line.
Dimas [21]

Answer:

c. y = x - 6

Step-by-step explanation:

This question wants you to find the equation in slope-intercept form, each is y=mx+b, where m is the slope and b is the y-intercept. The first thing to do is find the y-intercept, to do this find the value of y when x equals zero. The way to do this is to look the value of y on the y-axis. In this case, the y-intercept is -6. Then, find the slope; since you are given the graph you can count out the slope. To do this find out how much the y and x values change. On this graph, y increases 1 when x increases 1, so the slope is 1/1 or one 1. So the equation is y=1x-6, which simplifies to y=x-6.
