Mathematics
1 answer:
kvasek [131]3 years ago
6 0

Answer:

The first answer.

Step-by-step explanation:

First of all, the circle on -3 did not have filling so that means it is not equal to z. Then we look on the circle on 6. It does have a filling which means it is equal to and greater than z. Now we look in between -3 and 6. Is there any white spots? If no, then we don’t have to use an OR. Therefore, the first answer is the only plausible answer.

ms. wilson draws a model of the factorization of a polynomial with integer factors. her model is partially complete. which equat
Oliga [24]
I'll just factor the above equation.

x² + 18x + 80

x² ⇒ x * x
80
can be:
1 x 80
2 x 40
4 x 20
5 x 16
8 x 10  Correct pair

(x+8)(x+10)
x(x+10) +8(x+10) ⇒ x² + 10x + 8x + 80 = x² + 18x + 80

x+8 = 0
x = -8

x+10 = 0
x = -10

x = -8

(-8)² + 18(-8) + 80 = 0
64 - 144 + 80 = 0
144 - 144 = 0
0 = 0

(-10)² + 18(-10) + 80 = 0
100 - 180 + 80 = 0
180 - 180 = 0
0 = 0

I think the algebra tiles will not be a good tool to use to factor the quadratic equation because the equation is not a perfect square quadratic equation.

Solve: x + 3 = -x + 7 (5 points)
makvit [3.9K]

Answer:

x = 2

Step-by-step explanation:

x + 3 = -x + 7

Add x to each side

x+x + 3 = -x+x + 7

2x+3 = 7

Subtract 3 from each side

2x = 7-3

2x = 4

Divide by 2

2x/2 = 4/2

x = 2

What is the answer to this problem -2x – 4 < 3x + 21
horsena [70]

Start with

-2x-4 < 3x+21

Add 2x to both sides:

-4 < 5x+21

Subtract 21 from both sides:

-25 < 5x

Divide both sides by 5. Since it is positive, we don't have to change the inequality sign:

-5 < x

So, the answer is x > -5
