Find an equation of the line with the given y-intercept and slope m.
4.2, m = -3.7
The equation of the line is 0.
(Type your answer in slope-intercept form.)
Answer:
y=4.2x-3.7
Step-by-step explanation:
Slope-intercept form is y=mx+b, so just plug in the numbers to where they go in the formula.
Last year, Josh had $20,000 to invest. He invested some of it in an account that paid 7% simple interest per year, and he invested the rest in an account that paid 9% simple interest per year. After one year, he received a total of $1560 in interest. How much did he invest in each account?
Answer: $12000 was invested at 7% while $8000 was invested at 9%.
Step-by-step explanation:
Based on the information given in the question, let the amount that was invested at 7% be n.
Therefore,
0.07n + 0.09(20000 - n) = 1560
0.07n + 1800 - 0.09n = 1560
-0.02n = 1560 - 1800
-0.02n = -240
n = 240/0.02
n = 120
Therefore, $12000 was invested at 7% while $8000 was invested at 9%.
what is the solution for this system of equations?
y= -1/4x + 6
y= x+1
9514 1404 393
Answer:
(x, y) = (4, 5)
Step-by-step explanation:
Equating the expressions for y gives ...
-1/4x +6 = x +1
5 = 5/4x . . . . . . . add 1/4x-1
4 = x . . . . . . . . . . multiply by 4/5
y = x +1 = 4 +1
y = 5
The solution is (x, y) = (4, 5).

Triangle ABC, shown in the diagram below, is an isosceles triangle
If the measure of <ABC is 42.5°, what is the measure of <ABC?
Answer:
A. 42.5
Step-by-step explanation:
The triangle shown is an isosceles triangle. An isosceles triangle haas two of its sides and base angles equal. Hence;
<ACB = <ABC (Base angles are equal)
Given
<ACB = 42.5°
Required
<ABC
According to the law above which says <ACB = <ABC , hence <ABC is also equal to 42.5°

Rearrange terms = −3A process on a machine has a standard deviation of 0.04 inches. If a product with specifications of /- 0.07 inches has to be processed on that machine, is the machine capable of performing that job
Answer:
No, it can't perform because C_p < 1
Step-by-step explanation:
We are told that a product with specifications of ± 0.07 inches has to be processed on that machine. This means that the product is centered on the machine.
Thus;
Specification Width = 2 × 0.07 = 0.14
Now, formula for capability index is;
C_p = specification width/(6 × standard deviation)
We are given standard deviation = 0.04. Thus;
C_p = 0.14/(6 × 0.04)
C_p = 0.5833
Now, for this process, C_p should not be less than 1. However in this case it is less than 1,thus it means that the machine will not be able to perform the job.

the tables represent two linear functions in a system. what is the solution to this system?
Answer: The solution is the point (-14, -54)
Step-by-step explanation:
When we have a system of linear equations like:
y = a*x + b
y = c*x + d
The solution of this system is the point (x, y) that is a solution for both equations, if we graph the lines, this point would be the point where the lines intersect.
To start with this, we need to find the equations of the lines, we will use the following:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Now, for the first table, we can use the points: (-3, -10) and (0, 2)
The slope of this line is:
a = (2 - (-10))/(0 - (-3)) = 12/3 = 4
then we have:
y = 4*x + b
To find the value of b, we can just replace one of the points in the equation, for example, we can use the point (0, 2), this means that we need to replace x by 0, and y by 2.
2 = 4*0 + b
2 = b
Then the equation for the first table is y = 4*x + 2
For the second table, we can use the points (0, -12) and (3, - 3)
Then the slope is:
a = (-3 - (-12))/(3 - 0) = 9/3 = 3
Then we have:
y = 3*x + c
And to find the value of c, we can do the same as before, now we use the point (0, -12) then:
-12 = 3*0 + c
-12 = c
Then the equation for this line is:
y = 3*x - 12
The system of linear equations is then:
y = 4*x + 2
y = 3*x - 12
To find the solution of the system, we must have that y = y, then we can write:
4*x + 2 = y = 3*x - 12
4*x + 2 = 3*x - 12
Now we can solve this for x.
4*x - 3*x = -12 - 2
x = -14
x = -14
Now we can replace this in one of the equations to find the value of y.
y = 3*(-14) - 12 = -54
Then the solution is the point (-14, -54)

The perimeter of a rectangular garden is 72 feet. If the width is 8 feet less than the length, write a system of equations involving the length and width, L and W, and solve it to find the dimensions of the rectangle.
Answer:
width -w
length l= 2*w+5
perimeter P=2w+2l, 52=2w+2l
system of equations:
52=2w+2l ------> 26 =w+l (1)
l= 2*w+5 (2)
substitute value of l from second equation into the 1st
26=w+2w+5
26=3w+5
21=3w
w=7
l=2w+5, l=2*7+5, l=19
Answer:

Jim is a salesman at a paper company. He sold 34 cases of paper to a law office. A case of paper contains 10 reams. How many reams of paper did he sell?
Answer:
Jim sold 340 reams of paper.
Step-by-step explanation:
The rule of three is a way to solve proportionality problems between three known values and one unknown. . That is, what is intended with it is to find the fourth term of a proportion knowing the other three. Remember that proportionality is a constant relationship or ratio between different magnitudes.
If the relationship between magnitudes is direct, that is, when one magnitude increases, so does the other (or when one magnitude decreases, so does the other), the direct rule of three should be applied as follows, a, b and c the known values and x the unknown:
a ⇒ b
c ⇒ x
So: [tex]x=\frac{c*b}{a}[/tex]
In this case, the rule of three can be applied as follows: if 1 box of paper contains 10 reams, 34 boxes of paper will have how many reams?
[tex]amount of reams=\frac{34 boxes*10 reams}{1 box}[/tex]
amount of reams= 340 reams
Jim sold 340 reams of paper.

Use the Distributive Property to solve the equation. 4x - 2(x - 3) = -4 + 5x - 5
Answer:
x=5
Step-by-step explanation:
First, open up the parentheses to get 4x-2x+6=-4+5x-5. Now, move all numbers without variables to the right and those with variables to the left to get 4x-2x-5x=-4-5-6. Simplify both sides to have -3x=-15. Now divide both sides by -3 to get x=5
