Answer:

x = -4

Step-by-step explanation:

Recall the Order of Operations rules:

Any work enclosed in parentheses must be done first if possible; in this particular problem, nothing inside parentheses is possible.

Next: multiplication and division, and

Finally: addition and subtraction.

Thus, we must focus on the multiplication -3(4x - 8) and 3(-8x - 1) first:

-3 -16x + 32 = -24x - 3

Adding 3 to both sides simplifies this equation to -16x + 32 = -24x.

Adding 16x to both sides isolates x on the right side: 32 = -8x.

Finally, x = -32/8, or x = -4

Step-by-step explanation:

-3-4 -32x=3×8x

-3-4-32x=24x

-6=32x+24x

-6=56x

:. x=-28/3

7x+8y=−46 2y − 6=0 What is the solution (x,y) to the system of equations above?

Answer:

(-10, 3)

Step-by-step explanation:

You can do it algebraically (substitution or elimination) or graphically. I will be using substitution to solve this.

Step 1: Rewrite 2nd equation

2y = 6

y = 3

Step 2: Plug in y

7x + 8(3) = -46

7x + 24 = -46

7x = -70

x = -10

Put it in coordinates and we have our final answer!

Please help im so confused (need asap)

$\qquad\qquad\huge\underline{{\sf Answer}}$

Let's solve ~

$\qquad \tt \dashrightarrow \:10 {x}^{2} - 25x + 15 = 0$

$\qquad \tt \dashrightarrow \:5(2x {}^{2} - 5x + 3) = 0$

$\qquad \tt \dashrightarrow \:2x {}^{2} - 5x + 3 = 0$

$\qquad \tt \dashrightarrow \:2x {}^{2} - 3x - 2x + 3 = 0$

$\qquad \tt \dashrightarrow \:x(2x - 3) - 1(2x - 3) = 0$

$\qquad \tt \dashrightarrow \:(x - 1)(2x - 3) = 0$

Therefore, the required factors are ~ (x - 1) and (2x - 3)

So, correct choice is B

1. Solve 4x + 5 > 5x – 2 for x.

Zigmanuir [339]

The answer should be X < 3 !

Explanation:

You first minus 5 to the other side which gave you -3 . Then you minus the 5x to the other side which gave you -1. After than just need to divide -1 to both side, switch the > and you’ll get the answer! Hope the explanation makes sense.

NO LINKS!! Explain your answers (show the support by showing the changes in x and y on your table). If the relationship is linea

sdas [7]

Answer:

Linear relationship: increasing or decreasing one variable will cause a corresponding increase or decrease in the other variable.

Inverse relationship: the value of one variable decreases as the value of the other variable increases.

Exponential relationship: a constant change in the independent variable (x) gives the same proportional change in the dependent variable (y)

Question 5

As the x-value increases (by one unit), the y-value decreases.

Therefore, this is an inverse relationship.

The y-values are calculated by dividing 35 by the x-value.

$\sf y=\dfrac{35}{x}$

**I believe there is a typing error in the table and that the y-value of x = 3 should be 11.67**

Question 6

As the x-value increases, the y-value increases. The y-value increases by a factor of 5 for each x-value increase of 1 unit.

Therefore, this is an exponential relationship.

$\sf y=5^x$

The absolute value inequality equation |2x – 1| > 3 will have what type of solution set?

Nataliya [291]

Answer:

(2x-1)>3

therefore 2x>3+1

2x>4

2x/2>4/2

therefore x>2
