Answer:

8

Step-by-step explanation:

a² = 10² - 6²

a² = 100 - 36

a² = 64

a = √64

a = <u>8</u>

So, the value of a is 8

If (a, -5) is a solution to the equation 3a = -2B - 7, what is a?
Andrew [12]
I think what you need to do is make B = -5
3a = -2(-5) - 7
3a = 10 - 7
3a = 3
a = 1

Determine if Ginny factored correctly. If not, explain where she made an error. Ginny made a mistake in step 1 when she identifi
il63 [147K]

Quadratic equations are second-order equations. Ginney made a mistake when she identified b = 31. It should be b = –31.

<h3>What is a Quadratic Equation?</h3>

A quadratic equation is an equation that can be written in the form of

ax²+bx+c.

Where a is the leading coefficient, and

c is the constant.

In order to find the mistake that Ginny made, we will first find the factors ourselves, therefore, we will factorize the trinomial,

6x^2 - 31x -30 = 0

As we can see that the value of constants are,

a = 6

b = -31

c = 30

6x^2 - 31x -30 = 0\\\\6x^2 - 36x+5x -30 = 0\\\\6x(x-6)+5(x-6)=0\\\\(6x+5)(x-6)=0

Therefore, the factors of the trinomial 6x^2 - 31x -30 = 0 are (6x+5) and (x-6).

If we compare our process with Ginny's process, we will find that she has taken the value of the constant b as 31 which is wrong.

Hence, Ginney made a mistake when she identified b = 31. It should be b = –31.

Find f(-2) for the function f(x) = 3r2 - 2x +7.<br> 0-13<br> O-1<br> O 1<br> O 23
viva [34]

Step-by-step explanation:

f(x) = 3x² - 2x + 7

f(-2) = 3(-2)² -2(-2) + 7

= 3(4) + 4 + 7

= 23
