The line that is parallel to this line will have the same slope of this line, as the two will never intersect. They will run side by side. The line y = 2x - 5 is written in slope-intercept form, which is y = mx + b. The value of m represents the slope, and in this equation m = 2. Therefore, the line we are looking for will have a slope of 2 also.
That line should also be in slope-intercept form. We now know the value of m, but we also know the value of x and y. The ordered pair (8, 10) is a point on the line, and every ordered pair is in the form (x, y). Therefore, x = 8 and y = 10. We can plug those values into y = mx + b, along with m = 2. That gives us:
10 = 2(8) + b We need to solve for b.
10 = 16 + b
b = -6

can someone please help me with this? (i will mark brainliest) (LMNP is rotated 180 degrees clockwise around the origin. what are the coordinates of L?)
Answer:
L's coordinates would go from being (x,y) to (-x, -y)
Step-by-step explanation:
So like, if L's coordinates were (5, 7) after rotation it would be (-5, -7)
If you were working backward and with L' being rotated you would do (-5, -7) change the sign and do (5,7) for L
Consenquently if you had a negative to begin with- L (-3, -4) L' would be the opposite sign and be (3,4)

Harper has a mask collection of 400 masks. She keeps 21% of the masks on her wall. How many masks does she keep on her wall?
Answer:
84
Explanation:
400 × 21%
= 400 ÷ 100 x 21 (because 21% = 21/100)
= 84

Oscar is planning to paint his house. For stability, the foot of his 17-foot ladder should be placed 4 feet from the house. How far up the side of the house will the ladder reach?
Answer: The side of the house will the ladder reached by ladder = 16.52 feet
Step-by-step explanation:
House is standing vertical on the ground.
By placing ladder, it will become a right triangle with hypotenuse as ladder.
By Pythagoras theorem,
[tex](hypotenuse)^2=(perpendicular)^2+(base)^2[/tex]
i.e.
[tex](17)^2=(Height \ of\ wall\ reached\ by\ ladder)^2+4^2\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)^2=289-16\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)^2=273\\\\\Rightarrow\ (Height \ of\ wall\ reached\ by\ ladder)=\sqrt{273}\approx16.52[/tex]
Hence, the side of the house will the ladder reached by ladder = 16.52 feet (approx)

You take measurements of the distance traveled by an object that is increasing its speed at a constant rate. The distance traveled d as a function of time t can be modeled by a quadratic function. What is the quadratic function that models distances of 21 ft at 1 s, 59 ft at 2 s, and 141 ft at 4 s?
Answer:
Follows are the solution to this question:
Step-by-step explanation:
Given:
[tex]s_1 = 21 \ \ t_1 = 1\\\\s_2 = 59 \ \ t_2 = 2\\\\s_3 = 141 \ \ t_3 = 4[/tex]
All points are on the graph including its quadratic function, in order to install their coordinates to values of x and y with the following values:
[tex]y= ax^2 + bx + c\\\\21=a+b+c[/tex] Inserting the coordinates of the first point
[tex]y= ax^2 + bx + c\\\\59 =4a+2b+c[/tex] Inserting the coordinates of the second point
[tex]y= ax^2 + bx + c\\\\141=16a+4b+c[/tex] Inserting the coordinates of the third point

A simple and easy math question.
Answer:
Cheetah
Blue Wildebeest
Brown Hare
Elk
Step-by-step explanation:
Divide the distance by the time.
Blue Wildebeest: 33 1/3 divided by 2/3 = 50
Brown Hare: 8 divided by 1/6 = 48
Cheetah: 7 divided by 1/10 = 70
Elk: 18 divided by 2/5 = 45
Now you have to order the animals from who has the biggest number(top) to who has the smallest number (bottom).
Answer:
Elk
Brown Hare
Blue Wildebeast
Cheetah
Step-by-step explanation:
Divide the distance by time to make percent
Blue Wildebeast- 33 1/3 ÷ 2/3 = 50%
Brown Hare- 8 ÷ 1/6 = 48%
Cheetah- 7 ÷ 1/10 = 70%
Elk- 18 ÷ 2/5 = 45 %
Least to Greatest: 45%, 48%, 50%, 70%
Least (top) to Greatest (bottom): Elk, Brown Hare, Blue Wildebeast, Cheetah

what is an equation of the line that passes through the point (-5, 7) and is parallel to the line x+5y=10?
Answer:
y = -1/5x + 6
Step-by-step explanation:
First rearrange x + 5y = 10 into y = mx + b format.
x + 5y = 10
5y = -x +10
y = -1/5x + 2
If a line is parallel to y = -1/5x + 2, it must have the same slope (-1/5).
Plug in for y = mx + b
x (x coordinate) = -5
y (y coordinate) = 7
m (slope) = -1/5
Solve for b.
7 = -5(-1/5) + b
7 = 1 + b
b = 6
y = -1/5x + 6 is parallel.

Answer:
EZ Excavation: y = 24.5x
Happy Hauling Service: y = 25x
Step-by-step explanation:
✔️Equation for EZ Excavation:
This can be written in slope-intercept form, y = kx
Where k is the unit rate/slope/constant of proportionality
y = cost
x = dirt
Thus,
k = y/x
Using any given pair of values from the table, say, (8, 196),
k = 196/8
k = 24.5
To write the equation, substitute k = 24.5 into y = kx
Thus:
y = 24.5x
✔️Equation for Happy Hauling Service:
This can be written in slope-intercept form, y = kx
Where k is the unit rate/slope/constant of proportionality
y = cost
x = dirt
Thus,
k = y/x
Using the coordinate of any point on the line, say (1, 25),
k = 25/1
k = 25
To write the equation, substitute k = 25 into y = kx
Thus:
y = 25x

Write the slope-intercept form of the equation of the line parallel to the
graph of 2x + y = 5 that passes through (0, 1).
Answer:
y = -2x + 1Step-by-step explanation:
2x + y = 5 ← given line
2x + y = C ← any parallel line
The line passing through (0, 1), therefore:
2×0 + 1 = C
C = 1
2x + y = 1 ← the parallel line that passes through (0, 1)
To change it to slope-intercept form we just need to subtract 2x from both sides:
y = -2x + 1

Teachers divided students into groups of 3. Each group of 3 wrote a report that had 9 pictures in it. The students used 585 pictures altogether. How many students were there in all?
Answer: 195
Step-by-step explanation:
585/9=65
65*3=195
Answer:
The answer is 195 students.
Step-by-step explanation:
There are 2 solutions for this.
1st solution.
1. Start with the basics, the number of pictures we have altogether, 585.
2. Divide the number 585 by the number of students which is 3 to identify the total number of students that reported the 585 pictures.
3. 585/3 = 195, the total number of students.
2nd solution.
1. Start with the total again, the number of pictures we have altogether, 585.
2. Divide the number 585 by the number of pictures in each group total received pictures which is 9.
3. 585 divided by 9 = 65.
4. Take the number 65 which is the number of groups and multiply it by 3 the number of students in each group which will lead to the answer 195 again.
5. 195 is the number of students in total.
6. Extra: to even re-check your answers, multiply 195 by 3 and u will get 585, because each student did 3 reports.

What is 5/3s+19/15= -3/5?
Answer:
I hope I didn't make mistakes, because I solved it without calculator
Step-by-step explanation:
[tex] \frac{5}{3} s + \frac{19}{15} = - \frac{3}{5} \\ \frac{5}{3} s = - \frac{3}{5} - \frac{19}{15} \\ \frac{5}{3} s = \frac{ - 9 - 19}{15} \\ \frac{5}{3} s = \frac{ - 28}{15} \\ s = - \frac{28}{15} \times \frac{3}{5} [/tex]
[tex]s = - \frac{28}{25} [/tex]
