Answer:
-3x - 6
Step-by-step explanation:
x - (4x + 6) becomes x - 4x - 6 after we've distributed the multiplication.
We can simplify this result as follows: -3x - 6

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

Answer:
[tex]g = \frac{ x - 2}{3} [/tex]
Answer: g=x-2/3
Step-by-step explanation:
When it says make g the subject it means make it on it's own in front of the '=' sign.
To make g the subject, you have to do the inverse to 'undo' the equation.
So, instead of adding 2, you have to take away 2 from x. This would now look like this:
x-2=3g
In algebra, when a number is next to a letter it means times. So instead of multiplying g by 3, you would have to divide x-2 by 3. This would now look like this:
x-2/3=g
Hope this helps :)
Estimate the surface area of the rectangular prism.

B) 32cm
C) 64cm
Answer:
it a
Step-by-step explanation:
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
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)

Find the area of the composite figure.
A. 51 m2
B. 81 m2
C. 102 m2
D. 420 m2
Answer:
B. 81 m²
Step-by-step explanation:
6x10 = 60
7x6 = 42
42/2 = 21
60+21 = 81
Answer:
B) 81 meters squared
Step-by-step explanation:
rectangle = 6 * 10 = 60
triangle = .5 * 6 * 7 = 21
60+21 = 81

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.
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)

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

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
