Hello.
Numbers with | | around them are the absolute value, meaning it is always positive.
|-1.43| and |-1.21| become 1.43 and 1.21
The equation is now 1.43 - 7.1 + 1.21
Solve.
1.43 - 7.1 + 1.21
-5.67 + 1.21
-4.46
-4.46 is the final answer.

Answer:
The equation is y = 12.5x I believe.
Answer;
The constant of proportionality (known as "speed" in this case) is 12.5 miles per hour.
The equation is
y = 12.5 × t
Explanation:
To find the constant of proportionality, divide one value in each pair by the other. If this relationship is a true direct proportionality , when you repeat these for every pair, your will come up with the same value:
For example
25
miles
÷
2
hours
=
12.5
miles
hour
A direct proportionality will always result in an equation that resembles this:
y = k x where y and x are the related quantities and k is the constant of proportionality. If you draw a graph using the values you have, the graph will show a straight line the passes through the origin. The slope of this line will be the constant of proportionality. And if the values given are real physical quantities, this constant will contain important information about the situation you are studying.
A line is represented by the equation y = 3x

7. Which of the following statements about the line is TRUE?
B. The line has a positive slope.
C. The point (1,4) lies on the line.
D. This line is parallel to the line whose equation is y - 2x - 7.
Answer:
B
Step-by-step explanation:
the line has a positive slope. you can tell by comparing the equation of the line to y=MX+c where m=slope= coefficient of x.
In this case the coefficient of x is positive 3.

angle a and b are supplementary angles. angle where a = 30+2x and b =x what is the measure of b degress
Answer:32 times 4 - 8 in degrees
Step-by-step explanation:
Since b = x, hence the value of b is 30 degrees
For two angles to be supplementary, the sum of the angles must be equal to 180 degrees
Given the angles
a = 30 + 2x
b = x
Equating the sum to 180
a + b = 180
30+2x + x = 180
30 + 3x = 180
3x = 180 - 30
3x = 150
x = 30 degrees
Since b = x, hence the value of b is 30 degrees

What is the slope of the line in the graph?
(-4,4) (4,-2)
m = (y2-y1)/(x2-x1)
m = ( -2-4)/(4-(-4))
m = -6/8
m = -3/4
Answer:
(4,3)
Step-by-step explanation:
Pick the 2 closest points that are perfectly on the line [(0,1) and (4,-2)]. Start at the first point (0,1) count to the right (From (0,1) to (4,1)) and that's our "x" number (4). Count down from that point (4,1) to the other predetermined point (4,-2) and you get your "y" number (3), thus (4,3)
The slope of a line is the ratio of the
A.
vertical change to the horizontal change between any two points on the line.
B.
x-intercept to the y-intercept.
C.
y-intercept to the x-intercept.
D.
horizontal change to the vertical change between any two points on the line.
Answer:
A.
vertical change to the horizontal change between any two points on the line.
Step-by-step explanation:
slope is the ratio of the vertical and horizontal changes between two points on a surface or a line. The vertical change between two points is called the rise, and the horizontal change is called the run. The slope equals the rise divided by the run: . This simple equation is called the slope formula.
The slope of a line is the ratio of the : A. Vertical change to the horizontal change between any two points on the line.
The slope of a line is the gradient of a line and it describes (represents) both the direction and steepness of an equation of a straight line.
Mathematically, the slope of a line is calculated by using this formula;
[tex]Slope. \;m = \frac{Change \; in \; y \;axis}{Change \; in \; x \;axis} \\\\Slope. \;m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Hence, the slope of a line is the ratio of the change in y-axis (vertical) to the change in x-axis (horizontal) of a line.
Additionally, the standard form of an equation of line is given by the following formula;
[tex]y = mx + b[/tex]
Where:
x and y are the points. m is the slope. b is the intercept.In conclusion, the ratio of the vertical change to the horizontal change between any two points on the line is the slope of a line.

The ratio of girls getting pickle pop chips to boys getting pickle pop chips is 20 to 11. If the girls
received 40 pickle pop chips, how many were given out altogether?
Answer:
The answer is 62
Step-by-step explanation:
the ratio given can be written as [tex]\frac{20}{11}[/tex].
first, we need to solve for how many boys received if the girls received 40.
let's write a new ratio to show this.
[tex]\frac{20}{11} = \frac{40}{x}[/tex]
notice how i was able to equal them to each other. this is because they represent the same rate.
to solve for x, cross multiply.
[tex]20x= 440\\[/tex]
now solve.
[tex]x=22[/tex]
the 22 represents how many boys will receive if the girls receive 40.
the question is asking how many will be given out all together. this implies that we should add 40 and 22.
[tex]40+22= 62[/tex]
62 pickle pop chips were given out.

You are buying t-shirts for the members of the math club. Each short-sleeve t-shirt costs
$10 and each long-sleeve t-shirt costs $17. If you purchase x short-sleeve t-shirts and y
long-sleeve t-shirts, write an equation to represent the total cost of the purchase.
Answer:
10x +17y=c (C is the total cost)
Answer:
10x+17y = z
Step-by-step explanation:
You have to multiple 10 by the number of t shirts you have(x)
Then you have to multiply 17 by the number of long sleeve shirts you have (y)
You then have to add 10x and 17y to get your total cost(z)
whats the distance between (1,2) and (4,-2)
Answer:
5 units
Step-by-step explanation:
Distance formula:
[tex]\sqrt{(x2-x1)^2 + (y2-y1)^2}[/tex]
Square root of those quantities. x2 and x1 mean the x values from one coordinate and the other, and the same goes for the y-coordinates. So y2-y1 represents (-2) - (2) and x2-x1 = (4) - (1). The answers you get (-4 and 3, respectively), now have to be squared, then added together. So (-4)^2 = 16 and (3)^2 = 9. Add 16 and 9 together you get 25. Final answer, you square root 25 and you get 5. Technically the square root of 25 is both positive and negative 5, but you cannot get a negative number for distance in this case (vectors are different).

To find the mass of an object given it's acceleration and the force acting on it we use the formula
[tex]mass = \frac{force}{acceleration} \\ [/tex]
From the question
force = 45 N
acceleration = 39 m/s²
We have
[tex]force = \frac{45}{39} = \frac{15}{13} \\ = 1.153846...[/tex]
