Can someone please help me!!
Elan Coil [88]

Answer:

13

Step-by-step explanation:

Firstly we would start off by simplifying the equation by doing the order of operations backward (PEMDAS -> SADMEP) and multiply -4 and -3 which would equal a positive 12

Next, we would divide 12 and -6 and get a negative 2

Finally, we would have the equation 1 - 12 + (-2)

We would solve the equation to get -13/(-1)³

This would make the -13 into a positive since any number over one is a whole number. -13 is getting divided by (-1) 3 times so it converts to a positive, then a negative, then back to a positive.

I hope this helped :3

The vertex of this parabola is at (-4, -1). When the y-value is 0, the x-value is 2. What is the coefficient of the squared term
Delicious77 [7]
Equation for parabola is
y = a ( x - h ) ^2 + k    where (h,k) is the vertex of the parabola. 

Given:  vertex (-4, -1)  h = -4; k = -1

y = a (x - (-4))^2 + (-1)
y = a ( x + 4)^2 - 1  plug in the values given for x and y.  y-value is 0 and x-value is 2

0 = a (2 + 4)^2 -1
0 = a (6)^2 -1   square 6
0 = a 36 - 1    add 1 to both sides to isolate the a
1 = 36 a         divide both sides by 36 to isolate the a
1/36 = a         the coefficient. 

i think you might have typed a number incorrectly if those are your answer choices.  Maybe the step by step process can still help you with your correct numbers.  :-)

Select the expression that are equivalent to 7a+4a​
TEA [102]

Answer:

7a+4a

we add same term.

a is common for both.

First take common term out

7a+4a  = a(7 + 4) (we add same term.

           = 11a

valkas [14]

(a) A suitable probability app tells you the probability of being less than 17,900 or more than 18,100 is about 4.55%.

(b) We want to find σ² such that 2P((18100-18000)/σ) ≤ 0.01. We use a factor of 2 because we want to count deviations both above and below 100 feet from the mean altitude. A suitable probability app can tell you the z-score such that P(Z)≤0.005, so we need to compute σ² = (100/Z)² from that result. Doing so, we get σ² ≈ 1507.
