What are the correct solutions to the quadratic
equation y2 – 13y + 40 = 0?
y = -5
or
y = -8
Answer above!
38=1/8k+47
Find the value of k
Answer:
[tex]k=-72[/tex]
Step-by-step explanation:
[tex]38=\frac{1}{8} k+47[/tex]
Switching the sides of the equation isn't required, but it helps to reduce confusion.
[tex]\frac{1}{8}k+47=38[/tex]
Since there is a positive 7, we are going to do the opposite operation, which is addition.
[tex]\frac{1}{8}k+47-47=38\\\text\:\:\:\:\:\:-47\:\:\:\:\:\:\:\:\:-47[/tex]
Simplify
+47 - 47 will cancel each other out, so we are left with:
[tex]\frac{1}{8}k=-9[/tex]
Now, multiply 8 to both sides, since the equation gives us 1 divided 8, so the opposite operation of division is multiplication.
[tex]8\cdot \frac{1}{8}k=8\left(-9\right)[/tex]
On the right side, we have the same thing as [tex]\frac{8}{1} \cdot \frac{1}{8}[/tex], so 8 we can cancel the equation on the right side since they are both the same number.
On the left, we have [tex]8\left(-9\right)[/tex], which is -72.
Therefore, [tex]k=-72[/tex].

Which side is the hypotenuse of XYZ
Caroline rolls a fair dice 90 times.
How many times would Caroline expect to roll an even number?
please answer quickly doing hw
Answer:
The probability to roll a number greater than 3 is 3 over the 6 total (1,2,3,4,5,6).
That can be simplified to 1/2 for the probability.
If she rolls the dice 90 times 90 x 1/2 or 45 rolls will receive a number greater than 3.

y = (x − 4)2 − 4
y = (x + 4)2 − 4
y = (x + 2)2 + 6
y = (x + 2)2 + 12
Answer:
Hi there!
The vertex form equation is y=a(x-d)^2+c where the vertex is (d, c).
The vertex is always the turning point when the y-values start to travel in the opposite direction from which they began traveling on the opposite side of the turning point. Therefore the point (4, -4) is the vertex.
y=a(x-4)^2-4
We can sub in a point on the graph in order to solve for the a-value. Let's use (6, 0), and sub that in for x and y.
0=a(6-4)^2-4
0=a(2)^2-4
4=4a
a=4/4
a=1
Therefore the equation is y=(x-4)^2-4
Hope this helps!

Solving Two Step Equations
9x + 6/3 = 5x + 2
Answer:
x = 0
Step-by-step explanation:
In this case it isn't exactly 2 steps, but you can still solve it.
First, simplify. Divide 6 with 3:
9x + (6/3) = 5x + 2
9x + 2 = 5x + 2
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Subtract 2 and 5x from both sides:
9x (-5x) + 2 (-2) = 5x (-5x) + 2 (-2)
9x - 5x = 2 - 2
4x = 0
Divide 4 from both sides of the equation to isolate the variable, x:
(4x)/4 = (0)/4
x = 0/4 = 0
x = 0 is your answer.
