Select the correct answer. Which equation represents a line that is parallel to the x-axis, is perpendicular to the y-axis, and has a slope of 0? A. y=4/5x + 4/5 B. y=5/4x
C. y=4/5 D. x=5/4
Answer: D
Step-by-step explanation: i did this
Answer:
C. y = 4/5Step-by-step explanation:
The line parallel to the x-axis has same coordinate for any value of x. The slope is zero.
This line has the form:
y = b, where b is the y-intercept.The only option with similar form is C
can anyone help me with this quickly please :)
To find the y-value that matches with the x-value, we will need to plug in the x-value and simplify the expression.
f(-2) = sqrt(-2 + 2) - 6
f(-2) = sqrt(0) - 6
f(-2) = -6
f(-1) = sqrt( -1 + 2) - 6
f(-1) = sqrt(1) - 6
f(-1) = 1 - 6
f(-1) = -5
f(2) = sqrt(2 + 2) - 6
f(2) = sqrt(4) - 6
f(2) = 2 - 6
f(2) = -4
f(7) = sqrt(7 + 2) - 6
f(7) = sqrt(9) - 6
f(7) = 3 - 6
f(7) = -3

Sienna has $40 to spend at the pumpkin patch each pony ride is $6
Answer:
There is no direct question on here so I'll just assume you're asking how many rides she can get on???
Step-by-step explanation:
6 x 1 = 6
6 x 2 = 12
6 x 3 = 18
6 x 4 = 24
6 x 5 = 30
6 x 6 = 36
6 x 7 = 42

6. Selena picked eight baskets of tomatoes. Her sister threw away one of
the baskets due to bruising. What percent were good?
Answer:
87.5%Step-by-step explanation:
Total baskets = 8Good baskets = 8 - 1 = 7Percent of good:
7/8*100% = 87.5%Total number of baskets of tomatoes = 8
Her sister threw away = 1
Number of baskets that are good = 8 - 1 = 7
Percentage of good baskets =

Answer:
The answer is B 10 L
Step-by-step explanation:
let milk and water in the mixture be 7x and 4x equal 55L
[tex]7x + 4x = 55 \\ 11x = 55 \\ x = 5[/tex]
[tex]7(5) = 35l \: milk \\ 4(5) = 20l \: water[/tex]
let x Liters of water he added so that the ratio is 7:6
[tex] \frac{35l \: milk}{20l \: water + x} = \frac{7}{6} [/tex]
cross multiply
[tex]35l \: milk \times 6 = (20l \: water + x)7 \\ 210l \: m= 140l \: w + 7x \\ 210l \: m - 140l \: w = 7x \\ 70l = 7x \\ \frac{70}{7} = \frac{7x}{7 } \\ x = 10 l \: water[/tex]

The length of side ST of the triangle SRT using concept of similar triangles is; ST = 22 km
How to find Length of Similar Triangles?We are given a Triangle PQR.
In Triangle PQR, Side PQ = 16 kilometers and side PR = 24 kilometers.
In Triangle SRT, Side RT = 33 kilometers.
Using concept of ratio of similar triangles, we can say that;
ST/RT = PQ/PR
Thus;
ST = RT * (PQ/PR)
ST = 33 * (16/24)
ST = 22 Km

what is 2,665 divided by 36 witha remainder?
74 R28
So sorry if its incorrect!
what is 13q - 9q + 5 = 17
the answer is: q=3
start by combining like terms (13q - 9q) which would leave you with 4q + 5 = 17. subtract 5 from both sides and you're left with 4q = 12. divide by 4 on both side and you get q = 3
Answer:
q=3
Step-by-step explanation:
13q - 9q + 5 = 17
13q - 9q = 17 - 5
4q = 12
4q/4 = 12/4
q = 3

In ΔPQR, r = 640 inches, q = 310 inches and ∠Q=30°. Find all possible values of ∠R, to the nearest degree.
Answer:
No Possible Triangles
Step-by-step explanation:
sinA/a = sinB/b
From the reference sheet (reciprocal version).
sinR/640 = sin30/310
Plug in values.
sinR= (640 (sin30))/ 310≈1.0322581
Evaluate.
R=sin −1 (1.0322581)=ERROR
Sine cannot be greater than 1.
The correlation coefficient for the costs and sizes of storage container is 0.55. How
are the costs and sizes of the containers related?
Answer:
There is a positive correlation between both variables.
Step-by-step explanation: That is to say, the relation between the cost and the size of the storage containers is growing.
As the size of the container increases the cost also increases.
The closer the correlation coefficient is to 1, the stronger is the positive relationship between the variables, in this case r = 0.52, so it could be concluded that the relationship between the variables is a medium positive correlation
A correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict changes to the value of another.
The costs and sizes of the containers are moderately correlated.
What is a correlation coefficient?A correlation coefficient is a statistical measure of the degree to which changes to the value of one variable predict changes to the value of another.
We have,
The correlation coefficient for the costs and sizes of the storage container is 0.55.
We know that,
Correlation coefficients whose magnitude is between 0.5 and 0.7 indicate that the variables are moderately correlated.
Correlation coefficients whose magnitude is between 0.3 and 0.5 indicate that the variables are a low correlation.
Since the correlation coefficient for the costs and sizes of the storage container is 0.55, it is between 0.5 and 0.7.
So it is moderately correlated.
Thus the costs and sizes of the containers are moderately correlated.

(c) How long did it take the diver to reach the surface?
Answer:
A scuba diver was exploring a reef 32.12 m below sea level. The diver ascended to the surface at a rate of 8.8 m/min.
a. using the formula d = rt, so 32.12 m = 8.8m/min (t)
b. it is reasonable to write the distance as positive because the diver is accending/ going up the surface

Topic: Parallel and Perpendicular Lines
Which of the following pairs of lines are perpendicular?
Select all that apply.

B.y = x 8 and y= -x –
C. y = x + 2 and y
-x+3
D.y = 3x + 2 and y = 3x - 2
E.y=3 and x = 4
F. y = x 8 and y = -x + 3
Answer:
Step-by-step explanation:
If slope of two lines are equal, then they are parallel lines.
If product of the slope of two lines is (-1), then they are perpendicular lines.
C) y = x + 2
Slope m1 = 1
y = -x + 3
Slope m2 = -1
m1 * m2 = 1 * (-1) = -1
These are perpendicular lines.
D) y = 3x + 2
Slope = m1 = 3
y = 3x - 2
Slope = m2 = 3
Slopes are equal. So, they are parallel lines.
E)y= 3
This line is parallel to x -axis.
x = 4
This line is parallel to y-axis.
So, both lines are perpendicular to each other.
F) y = x + 8
slope m1 = 1
y = -x + 3
Slope = m2 = -1
M1 * m2 = 1 * (-1) = -1
So, These are perpendicular lines
