The plus sign means that we have to sum all the terms inside of the second parenthesis, while the minus sign means that we have to change all the signs inside the last parenthesis:

(3x+5)+(2x-9)-(4x+3)=3x+5+2x-9-4x-3

Now we only have to gather all like terms:

3x+2x-4x+5-9-3 = (3+2-4)x+(5-9-3)=x-7

Solve 7|3f + 4| = 91 for f. A. –29 or 312⁄3 B. 3 or –17⁄3 C. –3 or 17⁄3 D. –312⁄3 or 29
ryzh [129]

Answer:

B

Step-by-step explanation:

Given

7 | 3f + 4 | = 91 ← divide both sides by 7

| 3f + 4 | = 13

The absolute value function always returns a positive value, but the expression inside can be positive or negative. Thus there are 2 possible solutions.

Solve 3f + 4 = 13 → 3f = 13 - 4 = 9 ⇒ f = 3

Solve 3f + 4 = - 13 ⇒ 3f = - 13 - 4 = - 17 ⇒ f = - \frac{17}{3}

As a check

Substitute these values into the left side of the equation and if equal to the right side then they are the solutions.

f = 3 : 7| 9 + 4| = 7| 13| = 7 × 13 = 91 ← True

f = - \frac{17}{3}

7 | - 17 + 4| = 7| - 13| = 7 × 13 = 91 ← True

Hence the correct solutions are B

Consider the following least squares specification between test scores and the student - teacher ratio: TestScore = 557.8 + 36.4
GenaCL600 [577]

Answer:

Test score_i= 557.8 +36.42 Income

If we increase the income by 1% that means that the new income would be 1.01 the before one and if we replace this we got:

Test score_f = 557.8  + (36.42* 1.01 Income)= 557.8 +36.7842 Income

And the net increase can be founded like this:

Test score_f -Tet score_i = 557.8 +36.7842 Income- [557.8 +36.42 Income] = 36.7842 Income -36.42 Income = 0.3642

So then the net increase would be:

C. 0.36 points

Step-by-step explanation:

For this case we have the following linear relationship obtained from least squares between test scores and the student-teacher ratio:

Test score_i= 557.8 +36.42 Income

If we increase the income by 1% that means that the new income would be 1.01 the before one and if we replace this we got:

Test score_f = 557.8  + (36.42* 1.01 Income)= 557.8 +36.7842 Income

And the net increase can be founded like this:

Test score_f -Tet score_i = 557.8 +36.7842 Income- [557.8 +36.42 Income] = 36.7842 Income -36.42 Income = 0.3642

So then the net increase would be:

C. 0.36 points
