Answer:

x=-4

Step-by-step explanation:

Ohhh you wrote 4 on the other post, not 4x.

Okay.

6(x+3)-4x=10

6x+18-4x=10

2x=-8

x=-4

Answer:

The value of x:

x = -4

Step-by-step explanation:

Solve for x:

6(x+3) - 4x = 10

Use <u>Distributive Property</u>:

6(x+3) - 4x = 10

6x + 18 - 4x = 10

Combine 6x and -4x together:

6x + 18 - 4x = 10

2x + 18 = 10

Subtract both sides by 18:

2x + 18 - 18 = 10 -18

2x = -8

Divide both sides by 2:

\frac{2x}{2} = \frac{-8}{2}

x = -4

So, therefore, the final answer is x = -4 .

The equation -2x2-8x = 10is rewritten in the form of -2(x-p)2+q = 0. What is the value of q?
scoundrel [369]

Answer:

q = -2

Step-by-step explanation:

-2x²-8x = 10 (divide both sides by -2)

x² + 4x = -5 (Apply completing the square method)

x² + 4x + (4/2)²= -5 + (4/2)²

x² + 4x + 2²= -5 + 2²    (reduce left hand side using a²+2ab+b² =  (a+b)² )

(x+2)² = -5 +4

(x+2)² = -1

(x+2)² + 1 = 0   (multiply both sides by -2)

(-2)(x+2)² + 1 (-2) = 0

-2[x - (-2)]² + (-2) = 0  ---> compare this with -2(x-p)² + q = 0

We can see that p = 2 and q = -2

Kathleen and Arnob both run from the park entrance along a loop. Kathleen starts walking from the park entrance and gets a 5-mil
Ilia_Sergeevich [38]

For this case, the first thing we must do is define variables.

We have then:

x: time in minutes

y: distance traveled.

We then have the following equations:

For Kathleen:

y = (\frac{1}{15}) x + 5

For Arnob:

y = (\frac{2}{15}) x

By the time Arnob reaches Kathleen we have:

(\frac{1}{15}) x + 5 = (\frac{2}{15}) x

From here, we clear the value of x.

We have then:

(\frac{2}{15}) x - (\frac{1}{15}) x = 5

(\frac{1}{15}) x = 5\\x = (15) * (5)\\x = 75 min

Answer:

it takes Arnob to catch up to Kathleen 75 minutes:

d. 75
