Answer:

4x iss the GCF that was factored out.

Step-by-step explanation:

Given the equation 4x²+8x, the greatest common factor will be the maximum factor of 4x² and 8x and that is 4x. Factoring out 4x from the given equation will result into the equation;

4x(x+2)

Note that the the resulting value in the bracket must have no other common factor after the GCF must have been factored out.

Therefore the expression that was factored out using GCF was 4x

What are the solutions to the system of equations? {y=2x2+6x−10 y=−x+5

inessss [21]

Answer: x = -5, 3/2 y = 10, 7/2

Explanation:

y = 2x^2 + 6x - 10 (1)
y = - x + 5 (2)

=> 2x^2 + 6x - 10 = - x + 5
2x^2 - 7x - 15 = 0
(2x - 3)(x + 5) = 0
=> 2x - 3 = 0
2x = 3
x = 3/2
=> x + 5 = 0
x = -5

According to (2):

y = -x + 5
y = -(-5) + 5
y = 5 + 5 = 10

y = -x + 5
y = -(3/2) + 5
y = -(3/2) + 10/2
y = 7/2

In a survey, 400 people were asked to choose one card out of five cards labeled 1 to 5. The results are shown in the table. Com

-BARSIC- [3]

Answer:

The value of the experimental probability is greater

Step-by-step explanation:

For the theoretical probability;

the probability that a card with the number 3 is selected is 1/5

We consider that the probabilities of each selection are equal, for the theoretical probability

For the experimental, we simply place the frequency of the selection 3 over the total

that will be 128/400 = 8/25

As we know that 8/25 is greater than 1/5

We can conclude that the value of the experimental probability is greater than that of the theoretical

Find the maximum value of the function for the polygonal convex set determined by the given system of inequalities.

V125BC [204]

Answer:

A. at (8,7) the maximum value is 98

Step-by-step explanation:

First draw the region, that is bounded by all

inequalities. This is the triangle with vertices

(6,1), (2,5) and (8,7).

Now you can see where the line f(x,y)=7x+6y

intersect this region. The maximum value will be

at endpoints of this region:

• at (6,1), f(6,1)=7-6+6-1=42+6=48;

at (2,5), f(2,5)=7·2+6.5=14+30=44;

• at (8,7), f(8,7)=7.8+6-7=56+42=98.

Thus, the maximum value of the function is 98 at

the point (8,7).

Slav-nsk [51]

Answer:

T + V = 50

2T + (3/2) * V = 90

2T + 1.5V = 90

T = 50 * 1.5 - 90 * 1 / 1 * 1.5 - 2*1 = 30

V = 1 * 90 - 2 * 50 / 1 * 1.5 - 2 * 1 = 20

Step-by-step explanation:

T = 30

V = 20
