Answer:

the vertex of this parabola is at (-6, 2).

Step-by-step explanation:

Compare the given y=-(x+6)² + 2 with the standard vertex form:

y = a(x - h)^2 + k. We see that

h must be -6 and k must be 2.

Thus the vertex of this parabola is at (-6, 2).

531 = ( X × 6) + 21 LAST QUESTIONNNN

Monica [59]

To solve for X: First you multiply x and 6 then subtract 21 on both sides and then divide by 6

531 = ( X × 6) + 21
531 = 6X + 21
510 = 6X
85 = X

Simplify the expression by combining like terms. 4y+7x- 2y+4x

juin [17]

Hello!

Answer:

$\boxed{2y+11x}$

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, you switch sides. *Group like terms*

$4y-2y+7x+4x$

Then, you add the similar to elements. You can also add the numbers from left to right.

$4y-2y=2y$

$2y+7x+4x$

$7x+4x=11x$

$\boxed{2y+11x}\checkmark$ , is the correct answer.

Hope this helps!

Have a nice day! :)

Pani-rosa [81]

Answer:

f(-10)=53

Step-by-step explanation:

Let

f(x)= $x^{2}$ +5x+3.............(1)

we have to find

f(-10)=?

for this we will put x=-10 in equation (1)

f(-10)= $-10^{2}$ +5(-10)+3

f(-10)=100-50+3

f(-10)=53
