5x+9=17x-4x+81 what is the answer?

1 answer:

8 0

5x+9=17x-4x+81
-------------------------
Simplify and combine like terms
5x+9=17x+-4x+81
5x+9=(17x+-4x)+(81)
5x+9=13x+81
-----------------------------------
Subtract 13x from each side
5x+9-13x=13x+81-13x
-8x+9=81
-------------------------------------------
Subtract 9 from each side
-8x+9-9=81-9
-8x=72
------------------------------------------------
And now divide each side by -8
-8x ÷ -8 = 72 ÷ -8
x = -9

Lapatulllka [165]

Answer:

Step-by-step explanation:

let a=Ann's amt., b=Betty's amt.

a=2b+9

b+2b+9=60

3b+9-9=60-9

3b=51

b=$17

a=34+9=$43

which of the following represents the equation of the line with an x- intercept of 6 that passes through the point (4,4)?

luda_lava [24]

Answer:

$y=-2x+12$

Step-by-step explanation:

To write the equation of a line, find the slope between two points. Substitute two points into the slope formula. If the equation has an x-intercept of 6 then the line passes through the point (6,0). Use (6,0) and (4,4) in the formula.

$m = \frac{y_2-y_1}{x_2-x_1} =\frac{4-0}{4-6} =\frac{4}{-2} =-2$

Since m = -2, substitute its value and the point (6,0) into the point slope form. Then simplify.

$y-y_1 = m(x-x_1)\\y-0 = -2 (x-6)\\y=-2x+12$

I need help with numbers 20,21,and22

julsineya [31]

Answer:

20) the answer is -43

21) the answer is 25

22)the answer is -5

Step-by-step explanation:

20) $\frac{p(p+n^{2})}{6}$

n=-7

p=-6

we have:

$\frac{-6*(-6+(-7)^{2})}{6}\\\\\frac{-6*(-6+49)}{6}\\\\\frac{-6*(43)}{6}\\\\\frac{-258}{6} \\-43$

21) mp-(p-(m-n))

m= -1 n=-6 p=-10

-1*-10-(-10-(-1-(-6)))

10-(-10-(5))

10-(-15)

10+15=25

22) $m-\frac{m+m}{2} - n$

m=1 n=5

1- $\frac{1+1}{2} -5$

1- 2/2 -5

1-1-5 =-5

Please I need help Question: What are the solutions to this graph?

I am Lyosha [343]

Answer:

The solution to the graph are x = -2 and x = 2

Step-by-step explanation:

Here, we want to get the solution to the graph

As we can see, the graph is parabolic; which is a property of a quadratic polynomial

The solution refers to the value at which the graph plot crosses the x-axis

In other words, the solutions to the graph are represented by the point at which we have the graph crossing over the x-axis

We can see this happen at two points

These are the points x = -2 and x = 2
