Answer:
(-2, -4)
Step-by-step explanation:
[y = 2x, y = -x -6]
Solve by substitution:
-x - 6 = 2x
simplify
3x = -6
divide
x = -2
Plug back in one equation to solve for y coordinate:
y = 2(-2)
y = -4
(-2, -4)
Which equation represents the relationship between x and y?
A. y = x + 25
B. y = 25x
C. x =25y
D. x = y +25

Answer:
[tex]64x^{12}[/tex]
Step-by-step explanation:
We have to use the law of indices for finding the equivalent expression.
[tex](8x^{5})^{2} = 64x^{10}[/tex] We square 8, which is 64 and multiply the two powers.
[tex](x^{4})^{\frac{1}{2}} = x^{2}[/tex] We multiply the 2 powers giving us, [tex]\frac{4}{2}[/tex], which simplifies to 2.
[tex]64x^{10}[/tex] × [tex]x^{2}[/tex] = [tex]64x^{12}[/tex] This is the answer as we multiply the two indices together.
I hope this helps!! ^-^
Answer:
64x¹²
Step-by-step explanation:
(8x^5)^2 × (x^4)^1/2
64x^10 × (x^4)^1\2
64x^10 × x^2
Calculate:
64x^12

Answer:
She will hire EZ Excavation.
Step-by-step explanation:
For a company EZ Excavation,
Per cubic yards cost of the dirt = [tex]\frac{\text{Total cost}}{\text{Volume of the dirt}}[/tex]
= [tex]\frac{196}{8}[/tex]
= $24.5
Total cost of 40 cubic yards of the dirt = 40 × 24.5
= $980
For second company Happy Hauling service,
Per cubic yard cost of the dirt = [tex]\frac{25}{1}[/tex]
= $25
Cost of 40 cubic yards of the dirt = 40 × 25
= $1000
Budget of the contractor = $1000
Cost of dirt offered by EZ Excavation is in her budget and she is saving $20.
Therefore, she will hire EZ Excavation.

This is an example of positive nonlinear association
Step-by-step explanation:
So we know for a fact that the relationship between the the variables in the scatter plot is positive because its going up
The relationship is non linear because it has a curve
The given scatterplot is option C. Positive Linear Association.
Here, we have,
we know that,
Scatterplots are the plotting of set of points on a vertical axis and an horizontal axis. The shows the correlation extent between the numbers of the observed quantities.
Given is a scatterplot.
A scatterplot is positive if an increase or decrease in one of the quantity results in the corresponding increase or decrease in the other quantity.
If it is opposite, then the relation is negative.
Here, when the x value increases, y value is also increasing.
So the relationship is positive.
A scatterplot show a linear relationship, if the values are closely resembling in a line.
Here the points are closely resembling on a line.
So it is linear.
Hence the relationship is positive linear relationship.

5. Write an equivalent expression to 1/4 (24x + 7 – 12x).
Answer:
Step-by-step explanation:
The easiest and most proper way to approach this task is to combine like terms inside parentheses: (24x + 7 – 12x) => (12x + 7).
Then (1/4)(24x + 7 – 12x) = (1/4)(12x + 7). This is an acceptable answer. There is the option of carrying out the multiplication, which results in
3x + 7/4, which is another acceptable answer.

There are 5 inches of water in a bucket after 212 hours of a rainstorm. How much water will there be in the bucket after 8 hours if the rain continues at the same rate?
Answer:
0.188 inches
Step-by-step explanation:
Given that,
There are 5 inches of water in a bucket after 212 hours of a rainstorm
We need to find how much water will there be in the bucket after 8 hours if the rain continues at the same rate.
5 inches = 212 hours
1 hour = (5/212) inches
For 8 hours,
[tex](\dfrac{5}{212})\times 8\\\\=0.188\ \text{inhces}[/tex]
Hence, there will be 0.188 inches of water after 8 hours.

The number of standard deviations between a score and the mean score is indicated by a z-score. What was Cindy's
Z-score on the science test?
a. -2.2
C. 16
b. 100
d. 2.2
Based on the test scores of the students, Cindy's z-score on the science test is 2.2
How to determine the z-score of Cindy?We start by calculating the mean of the scores using:
Mean =Sum/Count
So, we have:
Mean = (75 + 80 + 90 + 100 + 75 + 85 + 80 + 80 + 90 + 85)/10
Mean = 84
Using a statistical calculator, the standard deviation is:
Standard deviation = 7.35
The z-score is then calculated using:
z = (x - mean)/standard deviation
Cindy's score is 100.
So, we have:
z = (100 - 84)/7.35
Evaluate
z = 2.2
Hence, Cindy's z-score on the science test is 2.2
