Answer:
x = - 5
Step-by-step explanation:
Remember that f(x) is the same value as y. So if f(x) = 1 then y = 1
There is only 1 point that has a y value of 1 and it is on the far left. The value you want is - 5
The answer is x = - 5 when f(x) = 1
If VZ=p–7 and WY=p–21, what is the value of p?
Answer:
35
Step-by-step explanation:
By the triangle midsegment theorem, 2(WY)=VZ.
So, 2(p-21)=p-7, meaning p=35

Enter your answer in the answer box and then click Check Answer
Answer:
y = 1/4x + 17/4
Step-by-step explanation:
first lets umm find the slope
use points that you can um clearly see ?
(4, 6) and (8, 7)
so use the equation y2 - y1/ x2 - x1
soooo
7 - 6/ 8 - 4
1 / 4
so it looks like:
y = 1/4x + b
so far
now we have to find the y-intercept with a point we did not use yet
but i have a little trouble so ill try my best to estimate a point
(2, 5)
we substitue
5 = 1/4(3) + b
5 = 3/4 + b
b = 5 - 3/4
b = 17/4

What the answer to PTR?
Answer:
∠ PTR = 140°
Step-by-step explanation:
∠ PTQ and ∠ RTS are vertical and congruent, thus
2x + 16 = x + 28 ( subtract x from both sides )
x + 16 = 28 ( subtract 16 from both sides
x = 12
Thus ∠PTQ = x + 28 = 12 + 28 = 40°
∠ PTQ and ∠ PTR are adjacent and supplementary, thus
∠ PTR = 180° - 40° = 140°

Solve: x2 − x − 6 x2 = x − 6 2x 2x 12 x after multiplying each side of the equation by the lcd and simplifying, the resulting equation is .
On factorization of the equation x² − x − 6 = 0. Then the values of x are −2 and 3.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The equation is given below.
x² − x − 6 = 0
On factorization, we have
x² − 3x + 2x − 6 = 0
x(x − 3) + 2(x − 3) = 0
(x − 3)(x + 2) = 0
x = −2, 3
The values of x are −2 and 3.

A rectangular table that is placed lengthwise against a wall is 8 feet long
and 4 feet wide. Balloons will be attached 8 inches apart along the three
exposed sides, with one balloon at each of the four corners. How many balloons are needed?
Considering the perimeter of the rectangular table, it is found that 36 ballons are needed.
What is the perimeter of a rectangle?The perimeter of a rectangle of length l and width w is given by:
P = 2(l + w).
In this problem, the dimensions of the table are l = 8 ft and w = 4 ft, hence the perimeter is of:
P = 2(l + w) = 2 x 12 = 24 ft.
Ballons will be attached 8 inches = 2/3 feet along the perimeter, hence the number of ballons needed is given by:

Molly bought 4.25 pounds of fish for $10.20. What is her unit rate (cost per pound)?
Answer:
$2.40 per pound
Step-by-step explanation:
Take the cost and divide by the pounds
$10.20/ 4.25 pounds
$2.40 per pound
Answer: The answer is 2.4
To find out the cost per pound, you just have to divide. For example, in this problem, you would divide 10.20 by 4.25 to see how much money it is for one pound of fish

Answer:
p = 6, q = - 1
Step-by-step explanation:
Using the rules of exponents
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{(m+n)}[/tex] , [tex](a^{m}) ^{n}[/tex] = [tex]a^{mn}[/tex]
Given
xy = 32 , tat is
[tex]2^{p}[/tex] × [tex]2^{q}[/tex] = [tex]2^{5}[/tex]
Since the bases on both sides are equal, equate the exponents
p + q = 5 → (1)
Also
2xy² = 32 ( divide both sides by 2 )
xy² = 16 , that is
[tex]2^{p}[/tex] × [tex](2^{q}) ^{2}[/tex] = 16
[tex]2^{p}[/tex] × [tex]2^{2q}[/tex] = [tex]2^{4}[/tex] , then p + 2q = 4 → (2)
Thus
p + q = 5 → (1)
p + 2q = 4 → (2)
Subtract (1) from (2) term by term
q = - 1
Substitute q = - 1 into (1) for corresponding value of p
p - 1 = 5 ( add 1 to both sides )
p = 6

Given f(x) = -2x and g(x) = 4x - 8, find h(x) = f(x) + g(x).
f(x) = -2x and g(x) = 4x - 8, find h(x) = f(x) + g(x).
Replace f(x) and g(x) with their given values:
h(x) = -2x + 4x -8
Combine like terms:
h(x) = 2x -8
A bacteriologist estimates that there are 5.2×10^4 bacteria growing in each of 20 petri dishes. About how many bacteria in total are growing in the petri dishes? Express your answer in scientific notation
Answer:
1X10^6
or
1.04x10^6
Step-by-step explanation:
You start by multiplying 5.2x10^4 by 20 because there are 20 petri dishes with this amount growing, and you get 1,040,000. Now we need to convert it to scientific notation. We know that 1,000,000 is 10^6, so we would move the decimal to the left 6 places and get 1.04x10^6. This is in scientific notation, but we need to keep in mind significant figures (sig figs), so your final answer would be 1x10^6, if that is not what your instructor is looking for, try 1.04x10^6.

Tracy has a cell phone plan that provides 250 free minutes each month for a flat rate of $29. For any minutes over 250, Tracy is charged $0.35 per minute. Which of the following piecewise functions represents charges based on Tracy's cell phone plan?
Answer:
[tex]\frac{29,x\leq 250}{29+0.35(x-250)x\geq 250}[/tex]
Step-by-step explanation:
Let x represent the total time spent calling and f(x) represent the charges.
Since Tracy is charged $29 for 250 free minutes, hence:
For x ≤ 250, f(x) = $29
Tracy is charged an extra $0.35 per minute for calls over 250 minutes, hence:
For x ≥ 250, f(x) = 29 + 0.35(x - 250)
Therefore this can be represented by the piecewise function:
f(x)= [tex]\frac{29,x\leq 250}{29+0.35(x-250)x\geq 250}[/tex]
