Answer:
[tex]y = 2 {(x + 2)}^{2} + 62[/tex]
Step-by-step explanation:
vertex form is
[tex]y = a {(x - h)}^{2} + k \\ where \: (h. \: k) \: is \: the \: vertex[/tex]
our original equation
[tex]2 {x}^{2} + 8x + 70[/tex]
first we will find the x value using the formula
[tex]x = - \frac{b}{2a} \\ - \frac{8}{2(2)} = - \frac{8}{4} = - 2 \\ x = - 2 = h[/tex]
plug the value of x back into the original equation to solve for y
[tex]y = 2 {x}^{2} + 8x + 70 \\ y = 2 ({ - 2}^{2} ) + 8( - 2) + 70 \\ y = 2(4) - 16 + 70 \\ y = 8 - 16 + 70 \\ y = 78 - 16 \\ y = 62 = k[/tex]
substitute this back into our vertex form and not forgetting the coefficient a = 2
[tex]y = 2 {(x - ( -2))}^{2} + 62 \\ y = 2 {(x + 2)}^{2} + 62[/tex]

What do you call raising a base to the exponent 2?
Answer:
When exponents are raised to another exponent, the exponents are multiplied. (a m) n = a (m × n) EX: (2 2) 4 = 4 4 = 256 (2 2) 4 = 2 (2 × 4) = 2 8 = 256

What is the slope?
Answer:
The slope is 4 or 4/1.
Step-by-step explanation:
Since these are all in numbers evenly divisible by 10, we can go ahead and make this easier by dividing everything by 10. When we do this, we can see a point crossing an intersection at (3,1), or if you left it, (30, 10). Next, we can see another point crossing another intersection at (4,5) or (40, 50). Since we have two points that are easy for us to subtract, we can use the slope formula. The formula is as follows: y2-y1 / x2-x1. We can pick which of these we want to be 1 or 2, but whichever one we pick has to be 1 or two on both the top on the bottom. for example, I did (50-10) / (40-30). That gets us 40/10. If you divided by ten in the first place, you would get 4/1. From there, if you have the bigger answer, you need to simplify to simply 4. The shorter answer doesn't need to be simplified because we already simplified. I hope this helps!

D. 12.85
Answer:
The answer so simplyfjdjdnxkxndndjxjfnfngkdjsjajajjdjfj the answer is D
Answer:
hi robertlyonsdamron the answer will be B
Step-by-step explanation:
You can use the order of operations to evaluate the expression. Perform the subtraction inside the parentheses: two minus three equals negative one. Evaluate the exponents: two to the sixth power is sixty-four. Multiply and divide in order from left to right: Twelve point six times negative one equals negative twelve point six, and sixty-four divided by four is sixteen. Add and subtract in order from left to right: Negative twelve point six plus sixteen equals three point four.

The largest perfect square under 100 would actually be 81 (9 x 9)
90 and 99 are not perfect squares and 64 is smaller than 81.
Answer:
a. none of these
Step-by-step explanation:
10 * 10 = 100, so 100 is a perfect square.
The next smaller perfect square is 9 * 9 = 81, but 81 is not in the choices.

Fernando opened a pizza box. Inside there was 3/4 of a pizza. He ate 1/3 of what was remaining. How much of a pizza did he eat? Fernando opened a pizza box. Inside there was 3/4 of a pizza. He ate 1/3 of what was remaining. How much of a pizza did he eat? Please include a sentence explaining your reasoning.
Answer:
He ate 1/4 of a pizza.
Step-by-step explanation:
1/3 basically means: There are 3 parts, you take 1 of those parts
so 3/4 means that there are three fourths. 3/4 divided by 3 = 1/4. He ate 1/4 of a pizza.

The correct answer is B/the second option.
The reason is that you can find slope by doing y2-y1/x2-x1, however x1 was put before x2 and therefore the slope was wrong. Good luck !! :)

Select all of the points which satisfy the linear inequality below.
-2x + 3y > 4
Answer:
x < − 2 + 3 y/ 2 linear inequality for x
y > 4/3 + 2x/3 linear inequality for y
Step-by-step explanation:
The point which satisfies the linear inequality is (-1,5) so option (C) is correct.
What is inequality?A difference between two values indicates whether one is smaller, larger, or basically not similar to the other.
In other words, inequality is just the opposite of equality for example 2 =2 then it is equal but if I say 3 =6 then it is wrong the correct expression is 3 < 6.
As per the given inequality,
-2x + 3y > 4
Put (-1,5) into the above inequality,
-2(-1) + 3(5) > 4
2 + 15 > 4
17 > 4 (True) thus (-1,5) will satisfy the inequality.
The rest points are not satisfying the inequality.
Hence " The point which satisfies the linear inequality is (-1,5)".

Find the unit rate:
150 words read in 8 minutes
Step-by-step explanation:
the unit rate: 150/8 × 60 minutes =
1,125 words/hour
Answer:
18,75 word read/minutes
or :
1,125 word read/hour
Step-by-step explanation:
The unit rate :
= 150 words read : 8 minutes
= 150/1 words read : 8/1 minutes
= 150/1 × 1/8 word read/minutes
= 150/8 word read/minutes
= 18 6/8 word read/minutes
= 18 3/4 word read/minutes
= 18,75 word read/minutes
= 1,125 word read/hour
PLEASE HELP MEEE ASAP
Step-by-step explanation:
first of all, g(x) has only negative functional result values (y) except for 0.
and a square is always positive.
so, the only possible right answers are the ones that include a minus ("-") sign.
the graph shows us that g(x) goes through the points (1, -3) and (-1, -3).
so, which equation turns an x = 1 into an y = -3 ?
therefore, the right answer must be D.
g(x) = -3x²
it works for both points :
-3 = -3×1² = -3 correct
-3 = -3×(-1)² = -3×1 = -3 correct

Graph each function for the given domain.
3x - y = 1 D(-3,-1,0,4)
Answer:
the following ordered pairs are your coordinates: (-3,-10), (-1, -4), (0,-1), (4,11)
Step-by-step explanation:
We can find these algebraically. First, you need to put your equation into the form y=mx+b. The m is the slope and the b is your y intercept. Once we have that equation, we just plug in the given X values to find their Y counterparts. The domain is simply the X coordinate and the range is the Y. I hope this helps!

i need help, can someone show me how to solve it
Answer:
9
Step-by-step explanation:
Simply plug -3 in for x.
-2(-3)^2-7(-3)+6
(-3)^2=9
9*-2= -18
-7*-3=21
-18+21=3
3+6=9
Answer:
f(-3) = 9
Step-by-step explanation:
Here we have a quadratic function in x: and we want to know the value of this function when x = -3.
Substituting -3 for x in f(x) = -2x^2 - 7x + 6, we get f(-3) = -2(-3)^2 - 7(-3) + 6, which works out to f(-3) = -2(9) + 21 + 6, or
f(-3) = -18 + 27 = 9
Thus, f(-3) = 9
