Answer:

B. x < 7

Explanation:

1. Move constant (40) to right side and change its sign. -8x > -16 - 40

2. Caculate the difference. -8x > - 16 - 40= -8x > -56

3. Divide both sides by -8.

-8x ÷ 8 > -56 ÷ -8

4. Solution : x < 7

Solve for w. | – w|≥2 Write a compound inequality like 1 < x < 3 or like x < 1 or x > 3. Use integers, proper fracti

Eduardwww [97]

Answer:

$-2 \geq w \geq 2$

Step-by-step explanation:

Given

$|-w| \geq 2$

Required

Solve for w

$|-w| \geq 2$

In absolution functions;

$|-w| = |w|$

So, the given expression can be rewritten as

$|w| \geq 2$

Removing the absolute sign, will gibe

$w \geq 2$ or $w \leq -2$

When the second inequality os rewritten, it gives

$w \geq 2$ or $-2 \geq w$

Reorder both inequalities

$-2 \geq w$ or $w \geq 2$

Lastly, both inequalities are combined

$-2 \geq w \geq 2$

. Which function's graph has a vertex at (-1, -3) and contains the point (2, 15)? HELPPP PLEASEE

AlexFokin [52]

Answer:

2(x+1)²-3

Step-by-step explanation:

Using the vertex formula we can write the follwoing equation

y=a(x+1)²-3

We need to solve for a

we know that when x= 2 y = 15

So we can write

15=a(2+1)²-3

15=9a-3

18=9a

a=2

Which means our final equation is

2(x+1)²-3

in standard form (just in case)

2x²+4x-1

How do you do simple algebra

n200080 [17]

Know the order of operations. However, one of the trickiest things about solving an algebra equation as a beginner is knowing where to start. Luckily, there's a specific order for solving these problems: first do any math operations in parentheses, then do exponents, then multiply, then divide, then add, and finally subtract

Three Texas drovers met on a highway and began to dicker as follows:

Alik [6]

Answer:

Jim's: 7
Duke's: 21
Hank's: 11

Step-by-step explanation:

Let J, D, and H represent the drove sizes of Jim, Duke, and Hank.

2(H -6 + 1) = (J +6 -1) . . . . . Hank's offer

3(D -14 +1) = (H +14 -1) . . . . Duke's offer

6(J -4 +1) = (D +4 -1) . . . . . . Jim's offer

These equations can be simplified to ...

2H - J = 15

3D - H = 52

6J - D = 21

Solution

Adding twice the second equation to the first gives ...

2(3D -H) +(2H -J) = 2(52) +(15)

6D -J = 119

Adding 6 times the third equation to this one gives ...

6(6J -D) +(6D -J) = 6(21) +(119)

35J = 245

J = 7

Using this value in the third equation gives ...

6(7) -D = 21

42 -21 = D = 21

Using the value of J in the first equation gives ...

2H -7 = 15

H = (15 +7)/2 = 11

Then the solution is (J, D, H) = (7, 21, 11).

Jim's drove had 7 animals; Duke's drove had 21 animals; Hank's drove had 11 animals.
