15, since 16-1=15, and you can use the y-intercepts as points to measure the distance from.

What is the answer to -9-8x=-2(7+4x)

Misha Larkins [42]

-9-8x=2(7+4x)

First you are going to distribute the 2 to (7+4x) then you will get both Xs on one side

-9-8x=2(7+4x)
-9-8x= 14+8x
+8x. +8x

=-9=14+16x

Now subtract 14 from both sides

9=14+16x
-14 -14

-23=16x

Divide by 16

Your answer will be x= -23/16

Answer:

No Solution

Step-by-step explanation:

Let us see the various conditions to check the number of solutions for a pair of linear equations.

Let our linear equations are

ax+by=c

px+qy=r

i) for Unique Solution

$\frac{a}{p}$ ≠ $\frac{b}{q}$ = $\frac{c}{r}$

$\frac{a}{p}$ ≠ $\frac{b}{q}$ ≠ $\frac{c}{r}$

ii) For No Solution

$\frac{a}{p}$ = $\frac{b}{q}$ ≠ $\frac{c}{r}$

iii) For many Solutions

$\frac{a}{p}$ ≠ $\frac{b}{q}$ = $\frac{c}{r}$

Let us see what ratio we have for our linear equation s

here

a=1 , b=-2 , c= 4

p=-3 , q = 6 , r = 12

$\frac{a}{p}$ = $\frac{1}{-3}$ = - $\frac{1}{3}$

$\frac{b}{q}$ = $\frac{-2}{6}$ = - $\frac{1}{3}$

$\frac{c}{r}$ = $\frac{4}{12}$ = $\frac{1}{3}$

- $\frac{1}{3}$ = - $\frac{1}{3}$ ≠ $\frac{1}{3}$

Hence it satisfies the second condition of No solution

What is three fourths the square of b

lana [24]

Simplifying it would make it 3/4b^2. I can't write it down the correct way, but it's three over four times b squared. Unless it's a square root, then things would be different.

Tresset [83]

Answer:

B. -1

Step-by-step explanation:

<u>Given expression:</u>

(x-5)(x+2)/(x+1)

<u>This is undefined when the denominator is zero:</u>

x + 1 = 0
x = -1

Correct choice is B
