Answer:
f=-2.75
Step-by-step explanation:
2(f-2)=3(2f+5)-8
2f-4=6f+15-8
2f-6f=7+4
-4f=11
f=-11÷4
=-11/4=-2/3/4=-2.75
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.

parabolic function going down from the left through the point zero comma twelve and through the point two comma zero and turning at the point four comma negative four and going up through the point six comma zero and continuing towards infinity

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!

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].

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.
