7 0

Answer:

B maybe? that doesnt equal any

Step-by-step explanation:

f(x)=3x^2+6x

f(2)=3(2)^2+6(2)

f(2)=3(4)+12

f(2)=12+12

f(2)=24

The solution to 2x2 – 11 = 87 is
Ilia_Sergeevich [38]
2x^2 - 11 = 87
2x^2 = 87 + 11 = 98
x^2 = 98/2 = 49
x = sqrt (49) =  + or - 7

I nee d help with this because my teacher didn't explain it well.
koban [17]

To solve 10x-35+3ax=5ax-7a, we'll need to assume that a is a constant and that we are to solve for the variable x.  To accomplish this, group all the x terms together on one side and all of the no-x terms on the other:

10x + 3ax - 5ax = -7a + 35

Factoring x out of the left side, we get:

x(10 - 2a) = 7(5 - a).  Dividing both sides by (10 - 2a), we get:

       7(5 - a)

x = ------------ = 7/2

      2(5 - a)

x has the value 7/2.

List the potential rational zeros of the polynomial function. Do not find the zeros.
Archy [21]
<span>f(x)=\boxed{1}x^5-3x^2+3x+\boxed{14}

</span>The potential rational zeros are divisors of 14:

\pm1;\ \pm2;\ \pm7;\ \pm14

and the quotient p/q where p is a divisor of 1, and q is a divisor of 14:

\pm\dfrac{1}{2};\ \pm\dfrac{1}{7};\ \pm\dfrac{1}{14}

Rachel traveled to five different areas (A, B, C, D, and E) to study the number of buckeye butterflies and the number of monarch
Ivenika [448]

Answer:

As we can see our our ration in Area B and Area D gives the same answer, so they are in proportion

Step-by-step explanation:

Given that

Rachel traveled to 5 areas to find  number of Buckeye and Monarch butterflies.

Areas Rachel Traveled to = A, B, C, D, E

The table given below shows her findings.

Area            Buckeye          Monarch

A                     15              16  

B                      27              36  

C                     12              25  

D                      24              32  

E                      44              33

Now lets find the ratio of Buckeye and Monarch Butterflies in these areas

Area A

Buckeye : Monarch = 15:16 = 0.9375

Area B

Buckeye : Monarch = 27:36 = 0.75

Area C

Buckeye : Monarch = 12:25= 0.48

Area D

Buckeye : Monarch = 24:32 = 0.75

Area E

Buckeye : Monarch = 44:33 = 1.334

As we know that if two ratios give same answer after solving the fraction then these ratios are in proportion.

As we can see our our ration in Area B and Area D gives the same answer, so they are in proportion.
