To find the y intercept of the graph of a linear equation we.
a. set x equal to 0 and solve the equation for x.
b. set x equal to 0 and solve the equation for y.
c. set y equal to 0 and solve the equation for x.
d. set y equal to 0 and solve the equation for y.
e. none of the above
Answer:
B
Step-by-step explanation:
A y-intercept's x will always be zero, there is no movement along the horizontal axis. Since you are looking for a y-intercept, you will solve for y.
If y varies directly as x and as the square of z, and y =
25
when x = 5 and z = 1, find y when x = 1 andz = 4
9
Answer: The answr is y=5/36 If my math is correct
Since the question is y=25/9 and x was 5 and z was 1, I thought 5 x 5 is 25, so x is 5. and 1 x 9 is 9 so z is 9. so then i multiplied 9x4 for z and 5 x 1 for x

Answer:
x=58 degrees
Step-by-step explanation:
A line is 180 degrees. So x+90+32=180. 32+90=122. Now you do 180-122 and you will get 58.
For questions 8-11, solve for x.
Answer:
Bruh
Step-by-step explanation:
Im so confused.... lol im not any help
What you're looking for is to simplyfy the like terms and then isolate the variable. So basically, write everything down and solve it like normal. We know that straight lines are worth 180° and right angles are 90° so that's what's gonna be on one side of the equal sign, and all the other numbers on the other side. Like this:
8.
180 = x + 1 + 3x + 9
180 = 4x + 10
170 = 4x
42.5 = x
If it's hard to see what I'm doing, just write the first part out and solve like regular algebra then check if you got the same answer.
Good luck :)

What is Linear Equation in 2 variables?
An equation is said to be linear equation in two variables if it is written in the form of ax + by + c = 0, where a, b & c are real numbers and the coefficients of x and y, i.e a and b respectively, are not equal to zero.
Given data ,
The value of C = m + 1
The value of B = m + 5
To calculate the value of 2 C + 3 B , substitute the value of B and C in the expression , we get
2 C + 3 B = 2 ( m + 1 ) + 3 ( m + 5 )
= 2 m + 2 + 3 m + 15
= 5 m + 17
Therefore , 2 C + 5 B = 5 m + 17
Hence , the expression 2 C + 3 B equals 5 m + 17 in standard form

A vine maple grows fast when it is planted under the cover of cedar trees. One month after it is planted it has grown 9 inches, and after eight weeks it had grown 14 inches.
Write an equation that models the growth, in inches, of the vine maple as a function of time, in weeks
Answer:
[tex]y=\frac{5}{4} x+4[/tex]
Step-by-step explanation:
Using y = mx+c
m= [tex]\frac{y^{2}-y^{2}}{x^{2}-x^{1}}[/tex]
m=[tex]\frac{14-9}{8-4}[/tex]
m=[tex]\frac{5}{4}[/tex]
c=y-intercept
The question says that at 8 weeks the maple had grown 14 inches
By using y=mx+c we can find the y-intercept using one of the points as the x and y values and by using the slope
[tex]14=8\times\frac{5}{4} +c[/tex]
14=10+c
14-10=10+c-10
4=c
y-intercept = 4
Therefore the full equation is
[tex]y=\frac{5}{4} x+4[/tex]
The value of y varies directly
Which function represents the
relationship between x and y if y =
14 when x =
7/2
Answer:
Step-by-step explanation:
Answer is 7/3
The function that represents the relationship between x and y is (y = 4x) and this can be determined by using the given data.
Given :
The value of 'y' varies directly with 'x'.If y = 14 when x = 7/2.The following steps can be used in order to determine the function that represents the relationship between x and y:
Step 1 - According to the given data, the value of 'y' varies directly with 'x'. So, the mathematical expression for this situation is:
[tex]y \; \alpha \; x[/tex]
y = kx --- (1)
Step 2 - It is also given that the value of y = 14 when x = 7/2.
Step 3 - Now, substitute the value of 'y' and 'x' in the above expression.
[tex]\rm 14=\dfrac{7}{2}\times K\\[/tex]
K = 4
Step 4 - Now, substitute the value of K in the expression (1).
y = 4x

Rubbing alcohol contains 70% isopropyl alcohol. Suppose you are adding 180ml of liquid that contains 45% isopropyl alcohol. How much liquid should be added of the higher concentration to obtain rubbing alcohol that is 70% isopropyl alcohol?
Starting with some solution of volume v and an alcohol concentration of 100c % , if you add 180 mL of 45% isopropyl to it, you get a mixture with a total volume of 180 mL + v.
Each mL of the starting solution contains c mL of alcohol. For example, if the concentration of the starting solution is 80% (so c = 0.8), then each mL contains 80% = 0.8 of one mL of alcohol.
Similarly, each mL of the added solution with 45% concentration contains 0.45 mL of alcohol.
You want the new solution to have a concentration of 70%, so that the ratio of the amount of alcohol in it to the total volume is 70%, meaning
cv + 0.45 (180 mL) = 0.7 (180 mL + v)
and you want to solve for v :
cv + 81 mL = 126 mL + 0.7v
cv - 0.7v = 126 mL - 81 mL
(c - 0.7) v = 45 mL
v = (45 mL) / (c - 0.7)
Judging by context clues, c lies somewhere between 0.7 and 1. (It can't be less than 0.7 because mixing this solution with any other solution of smaller concentration will never yield a solution of higher concentration.)
If, for example, c = 0.8, so that your starting solution is at 80% concentration, then you would need
v = (45 mL) / (0.8 - 0.7) = 450 mL
to be mixed with 180 mL of 45% solution to end up with 180 mL + 450 mL = 630 mL of 70% solution.
As another example, if you're mixing pure alcohol, so that c = 1, you would need
v = (45 mL) / (1 - 0.7) = 150 mL
to make a 180 mL + 150 mL = 330 mL batch of 70% solution. The fact that you would need less of a higher concentration solution is not surprising.
Sally is creating a rectangular quilt and the length is equal to five inches less then the width. The perimeter is 30 inches. What are the dimensions of the quilt
A. Width=5 and length= 10
B. Width=30 and length= 5
C. Width=10 and length =5
D. Width= 5 and length =30
Answer:
It is C
Step-by-step explanation:
c is the only answer that makes sense because 10 is 5 more than 5 as the length so 5 is 5 less than 10.
The dimensions of the quilt are width = 10 and length = 5 which is the correct answer would be option (C).
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
The perimeter of a rectangle = 2(L+W)
Where W is the width of the rectangle and L is the length of the rectangle
The length of the quilt Sally is making is five inches shorter than the width. The perimeter measures 30 inches which are given in the question.
The perimeter of a rectangle = 2L + 2W
30 = 2L + 2W
L + W = 15
The length is equal to five inches less than the width.
So L = W - 5
Substitute the value of L = W - 5 in the equation L + W = 15
W - 5 + W = 15
2W = 20
W = 10
L = 5
Therefore, the dimensions of the quilt are width = 10 and length = 5.

Pedro opened a deli in December. The table shows his profits and losses during his first four months of business. Month Profit/Loss ($) December + 724.37 January + 3,912.26 February - 1,051.51 March - 4,023.02 What is the overall profit or loss for the first four months the deli was open?
Answer:
437.90
Step-by-step explanation:
you add the negative numbers together, then the positive numbers. you take the answers from those and subtract them from each other.
The overall loss for the first four months the deli was open is $-437.90.
A firm has a profit when its income is greater than the cost. A loss is recorded when income is less than the total costs. A profit is represented with a positive sign (+) and a loss is represented with a negative sign (-).
In order to determine the overall profit or loss for the first four months add profits and subtract losses.
+ 724.37 + 3,912.26 - 1,051.51 - 4,023.02 = $-437.90.
Costs exceeds revenue so the Deli earns a loss of $437.90.
