Answer:
5(2x-8)+15=-15
10x-40+15=-15
10x-25=-15
+25 +25 (add 25 to both sides)
____________
10x=10
divide by 10 on both sides
x=1
Answer:
x=1
Step-by-step explanation:
First youd distribute the 5 to the 2x-8 so that way you can combine like terms and make the equation smaller
10x - 40 + 15 = -15
combine the -40 and 15
10x - 25 = -15
add 25 to both sides to get 10x by itself on the one side. you have to add 25 to the -15 because the two sides must stay balanced
10x = 10
divide by 10 to get x by itself. you must divide since x is being multiplied by 10
x=1

What are the zeros or x-intercepts of the parabola?
A) (0, -1) and (0,5)
B (2,0) and (-9,0)
C (-1,0) and (5,0)
D (0,-5) and (-5,0)
Answer:
C
Step-by-step explanation:
x-intercepts , when y=0 are
(-1,0) and (5,0)
Answer:
C
Step-by-step explanation:
The zeros are also known as x-intercepts so it is the points on the x axis.
For x-intercepts the y is 0 so it is (-1,0) and (5,0)

Sean has 9 liters of juice. He pours equal amounts of the juice into 4 pitchers. There is 0.5 of a liter of juice left. How many liters of juice are in each pitcher?
Answer:
There is 2.215 liters in each of the 4 pitchers.
Step-by-step explanation:
Let x be the number of liters in each of the 4 pitchers.
4x + 0.5 = 9
4x = 8.5
x = 2.125

The rule T(5,-3) is used for point (5,-1). Where is the translated point in the coordinate system
Answer:
Quadrant 4
Step-by-step explanation:
(5,-1), 5+5, -1-3 (10,-4) which is bottom left which is quadrant 4
The point (5, -1) is located in the fourth quadrant. Therefore, option B is the correct answer.
Given that, the rule T(5,-3) is used for point (5,-1).
What is the translation?A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.
Quadrant rules:
First Quadrant: - x > 0 and y > 0. Thus, the sign of a point will be ( +, +).
Second Quadrant: - x < 0 and y > 0. Thus, the sign of a point will be ( -, +).
Third Quadrant: - x < 0 and y < 0. Thus, the sign of a point will be ( -, -).
Fourth Quadrant: - x > 0 and y < 0. Thus, the sign of a point will be ( +, -).
By studying above rules we understood (5, -1) in fourth quadrant.
The point (5, -1) is located in the fourth quadrant. Therefore, option B is the correct answer.

Cindy did an experiment. She started out with 600 bacteria cells. She found that the growth rate of the bacteria cells was 4.1%. Create an equation for the situation that would work for any time, x.
Pls Help thx
Answer:
Step-by-step explanation:
Hello! Im doing the same problem for my midterm and I believe the answer would be 0.041x+600.
Since x represents the time, x can be anything. 0.041 would equal the percentage of 4.1% and you need the growth rate times the time to equal your answer. +600 would be what she started out with, which is the bacteria cells. Hope this answers your question!!!

Select the correct answer. Consider functions h and k. What is the value of ?
Answer:
Option (C)
Step-by-step explanation:
If two functions are f(x) and k(x),
(f o g)(x) = f[g(x)]
From the question given in the picture attached,
We have to find the value of (h o k)(1).
(h o k)(x) = h[k(x)]
= h[k(1)]
= h(3) [Since, k(1) = 3]
= 28 [Since, h(3) = 28]
Therefore, (h o k)(1) = 28 will be the answer.
Option (C) will be the correct option.
The correct option is C.
The calculation is as follows:
If two functions are f(x) and k(x),
(f o g)(x) = f[g(x)]
Now according to the picture
We have to find the value of (h o k)(1).
(h o k)(x) = h[k(x)]
= h[k(1)]
= h(3) [Since, k(1) = 3]
= 28 [Since, h(3) = 28]

Here is an inequality:
7x+6
2
< 3x + 2
Select all of the values that are a solution to the inequality.
Inequalities are used to relate unequal expressions
The values that are a solution to the inequality are: A. x = -3 and B. x = -2
The expression is given as:
[tex]\mathbf{7x + 6 < 3x + 2}[/tex]
Collect like terms
[tex]\mathbf{7x -3x < -6 + 2}[/tex]
[tex]\mathbf{4x < -4}[/tex]
Divide both sides by 4
[tex]\mathbf{x < -1}[/tex]
[tex]\mathbf{x < -1}[/tex] means that: the values of x are less than 1.
Hence, the values that are a solution to the inequality are: A. x = -3 and B. x = -2

The table represents some points on the graph of a linear equation.What is the rate of change of y with respect to x for this function?
Answer:
Step-by-step explanation:
what we know=
x is the independent variable and y is the dependent variable.
our co-ordinates can be expressed in the form of (x value, y value).
so... we only need two points for this so let's just list two points so it goes faster
A(-7,5)
B(-1,65)
alright, now we have two points. we're trying to find the rate of change, which in other words, is the slope.
m=(y-y1)/(x-x1) <-- plug in our points.
m=(65-5)/(-1-(-7)
m=60/(-1+7)
m=60/6
m=10
therefore the rate of change aka the slope of this table of values is 10.
