Answer:
x-8 to get the zero for the 8 you have to add it. And for the second part you have to subtract four from itself.
Step-by-step explanation:
From the expression (x - 8) (x + 4), the values of x need to be 8 or -4, for x to be equal to zero.
Given that:
(x - 8) (x + 4) = 0
The expression from above is the expanded form of a given quadratic equation.
To find the quadratic equation, we will use the values of one enclosed bracket to multiply the values of the other.
i.e.
(x -8) (x + 4) = 0
x² + 4x - 8x - 32 = 0
x² - 4x - 32 = 0
(So, this above expression shows the quadratic equation from which the roots of (x-8) (x-4) is being derived from)From the roots;
(x - 8) (x + 4) = 0
Let;
(x - 8) = 0 or (x +4) = 0
x - 8 = 0 or x + 4 = 0
x = 8 or x = -4
Therefore, we can conclude that the value of x needs to be 8 or -4 for x to be equal to zero.

What is m∠PTQ? a. 12 b. 40 c. 50 d. 140
HELP!!!
Answer:
B. 40°
Step-by-step explanation:
m<PTQ = (x + 28)°
m<RTS = (2x + 16)°
Angle PTQ and angle RTS are vertically opposite angles, therefore, m<PTQ = m<RTS
[tex] x + 28 = 2x + 16 [/tex]
Solve to find the value of x
[tex] x + 28 - 2x = 2x + 16 - 2x [/tex] (subtracting 2x from each side)
[tex] -x + 28 = 16 [/tex]
[tex] -x + 28 - 28 = 16 - 28 [/tex] (subtracting 28 from each side)
[tex] -x = -12 [/tex]
[tex] x = 12 [/tex] (dividing each side by -1)
Find angle PTQ:
m<PTQ = (x + 28)°
Plug in the value of x
m<PTQ = 12 + 28 = 40°

Matthew rode his bike 5/8 mile in 1/4 hour. What is the unit rate in miles per hour?
Answer:
The unit rate in miles per hour is 2.5 mph.
Step-by-step explanation:
Since Matthew rode his bicycle for 5/8 of a mile in a quarter of an hour, to determine the speed at which he was traveling we must perform the following calculation:
1/4 x 4 = 1 hour
5/8 x 4 = miles that would have been covered in one hour
20/8 of a mile would have been covered in one hour
20/8 = 2.5
2.5 miles would have been covered in an hour, with which his speed was 2.5 mph.

Answer:
a = 55/6
Step-by-step explanation:
Solving in steps:
3/5a = 5 1/23/5a = 11/2a = 11/2 : 3/5a = 11/2*5/3a = 55/6 or 9 1/6Consider the experimental situation described below. Ability to grow in shade may help pines in the dry forests of Arizona resist drought. How well do these pines grow in shade? Investigators planted pine seedlings in a greenhouse in either full light or light reduced to 5% of normal by shade cloth. At the end of the study, they dried the young trees and weighed them. Identify the experimental unit(s) or subject(s). (Select all that apply.)
Answer:
Pine tree seedlings
Step-by-step explanation:
An experimental unit refers to the subject or factor under investigation. The subject or factor is subjected to different treatments in the course of the study. In the case of the experimental situation described above, the pine tree seedlings are the experimental units that actually received the treatments.
The treatments included being subjected to full or reduced light in the greenhouse. The response of the seedlings to these treatments would determine the outcome of the study.

On the left:
There are 4 triangles that indicate -x, so this is -4
There are 3 circles that indicate -1, so these are -3.
Insert as an expression:
[tex]-4x-3[/tex]
On the right:
There are 2 triangles that indicate -x, so this is -2x.
There are 2 circles that indicate -1, so these are -2.
Insert as an expression:
[tex]-2x-2[/tex]
Combine both expressions into an equation:
[tex]-4x-3=-2x-2[/tex]
Solve for x. Add 3 to both sides:
[tex]-4x-3+3=-2x-2+3\\\\-4x=-2x+1[/tex]
Add 2x to both sides:
[tex]-4x+2x=-2x+2x+1\\\\-2x=1[/tex]
Isolate the variable. Divide both sides by -2:

2 The temperature in Chicago was - 10 degrees Fahrenheit. It then rose 5 degrees.
a. Write an equation that you can use to find the new temperature.
b. What is the new temperature?
C. Is your answer a positive or negative integer? Why?
Answer:
Step-by-step explanation:
Given
Initial Temperature = -10
Increment = 5
Required
Solving (a): Write an Equation
The equation is to add the initial temperature and the increment
i.e
Equation = Initial Temperature + Increment
Solving (b): Solve the equation
Substitute values for initial temperature and the increment
Result = -10 + 5
Result = -5
Solving (c):
It's a negative answer because the increment in temperature is not greater than the initial temperature

Brayden signed up for a streaming music service that costs $11 per month. The service allows Brayden to listen to unlimited music, but if he wants to download songs for offline listening, the service charges $1 per song. How much total money would Brayden have to pay in a month in which he downloaded 35 songs? How much would he have to pay if he downloaded s songs?
s = # of songs
y = total amount of money
$11 + $1(35) = y
Simplify the right side
$11 + $35 = y
Combine like terms
$46 = y
If he downloaded 35 songs, he would have ti pay $46
If he downloaded s amount of songs, he would have to pay $11 + $1s = y

Did the test and got it right.
The function g(x) = 2x + 3 if f(x) = 2(x + 1)² and f(g(x)) = 2(2x + 4)² option (C) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
The question is incomplete.
The complete question is in the picture, please refer to the attached picture.
Suppose f(x) = 2(x + 1)² and f(g(x)) = 2(2x + 4)². What is g(x)?
A.g(x) = x + 3
B.g(x) = x + 4
C.g(x) = 2x + 3
D.g(x) = 2x + 4
We have:
f(x) = 2(x + 1)²
Let take g(x) = 2x + 3
Find f(g(x))
f(2x + 3) = 2[(2x+3) + 1]²
= 2(2x + 4)² = f(g(x))
Thus, the function g(x) = 2x + 3 if f(x) = 2(x + 1)² and f(g(x)) = 2(2x + 4)² option (C) is correct.

Jesper Co begins its next year of operations with a Beginning Supplies balance of 1,400. The end of period count of inventory revealed an Ending Supply balance of 4,500. If COGS for the same period was 36,700, Purchases must have been what? 0 33.600 35.300 39.800 36.700
Answer:
Purchases= $39,800
Step-by-step explanation:
Giving the following information:
Beginning Supplies= 1,400
Ending Supply balance= 4,500
COGS= 36,700
To calculate the purchases, we need to use the following formula:
Purchases= COGS + desired ending inventory - beginning inventory
Purchases= 36,700 + 4,500 - 1,400
Purchases= $39,800
A make-your-own ice pop kit says to pour 4 fluid ounces of juice into each bag. How many ice pop bags can you fill with 1 quart of juice?
Answer: 8 bags.
Step-by-step explanation:
It is given that, a make-your-own ice pop kit says to pour 4 fluid ounces of juice into each bag.
We need to find the number of ice pop bags we can fill with 1 quart of juice.
We know that,
1 quart = 32 ounces
We have 32 ounces of juice and each bag contains 4 fluid ounces.
[tex]\text{Number of ice pop bags}=\dfrac{\text{Total juice}}{\text{Juice contained in each bag}}[/tex]
[tex]\text{Number of ice pop bags}=\dfrac{32}{4}[/tex]
[tex]\text{Number of ice pop bags}=8[/tex]
Therefore, 8 ice pop bags we can fill with 1 quart of juice.
Answer:
8 bags

determine the answer to 3+(-5) explain steps on number line
Answer:
-2
Step-by-step explanation:
When you add a negative number, instead of going 5 places ahead, it goes 5 places back on a number line.
So you would treat this like a subtraction problem. Instead of 3+(-5) it would act like 3-5.
Name all the segments in a triangle
Answer:
Every triangle has three medians, just like it has three altitudes, angle bisectors, and perpendicular bisectors. The medians of a triangle are the segments drawn from the vertices to the midpoints of the opposite sides. The point of intersection of all three medians is called the centroid of the triangle.
