Answer:
y = 2x + 6
Step-by-step explanation:
We are given the line R, which is y=2x+5, and we want to find the equation of the line that is parallel to this line, and that also passes through the point (-2, 2).
Parallel lines have the same slope, yet different y-intercepts.
So, we should first find the slope of y=2x+5.
The line is written in slope-intercept form, which is y=mx+b, where m is the slope and b is the y intercept.
As 2 is in the place of where m (the slope) should be, 2 is the slope of the line.
It is also the slope of the line parallel to it.
We can write the equation of the new line in slope-intercept form as well; here is the equation so far, with what we know:
y = 2x + b
We need to find b.
As the equation passes through the point (-2, 2), we can use its values to help solve for b.
Substitute -2 as x and 2 as y.
2 = 2(-2) + b
Multiply.
2 = -4 + b
Add 4 to both sides.
6 = b
Substitute 6 as b.
y = 2x + 6
On a scale drawing of a boat, 15 feet are represented by 10 inches. If the drawing was 8 inches long, how long was the boat?
Answer:
12 feet
Step-by-step explanation:
On a scale drawing of a boat, 15 feet are represented by 10 inches.
This means [tex]15\,\,feet=10\,\,inches[/tex]
[tex]1\,\,inch=\frac{15}{10}\,\,feet=\frac{3}{2}\,\,feet[/tex]
Now, find the length of the boat if the drawing was 8 inches long.
Length of the boat = [tex]8(\frac{3}{2})=12\,\,feets[/tex]
So, length of the boat is 12 feets if the drawing was 8 inches long.

The owner of Wayne's Auto Repair charges a
customer $285 for parts plus an hourly labor cost.
The customer paid for 2.5 h of labor and paid a total of
$490.
What is the hourly labor cost?
O $80.00 per hour
$82.00 per hour
0 $86.00 per hour
O $89.00 per hour
Answer:
$82 per hour
Step-by-step explanation:
Total cost to customer: $490
Cost for parts: $285
$490-$285 = $205
There is a total labor charge of $205.
The problem tells us that the customer paid for 2.5 hours of labor.
$205/2.5 hours = $82.00 per hour.

Ismail has 44 sweets more than Johan. If the number of sweets Johan has is of the
7/11 of the number of sweets Ismail has, how many sweets do they have altogether?
Answer:
121
Step-by-step explanation:
Find out the amount of units Ismail have more than Johan.
11 - 7 = 4 units
Since Ismail has 44 more sweets than Johan and 4 more units..
4 units = 44
1 units = 44 ÷ 4 = 11
Altogether, there's 11 units.
11 units = 11 x 11 = 121

Answer:
A. 6
Step-by-step explanation:
The equation should equal 20 so first subtract 2 from 20 which is 18 then divide 18 by 3 which is 6, 6 is your answer.
Opposite angles are equal
[tex]\\ \sf\longmapsto 3x+2=20[/tex]
[tex]\\ \sf\longmapsto 3x=20-2[/tex]
[tex]\\ \sf\longmapsto 3x=18[/tex]

Marco is building with bricks. He needs 560 bricks total to build a wall, but only has 445. The price per 5 bricks is $25. How much money does Marco need for a total of 115 bricks?
Answer:
575$
Step-by-step explanation:
If each 5 bricks is 25$ and Marco already has 445 all he needs is 115 more bricks and 115 divided by 5 is 23 so 23 groups of 5 bricks and 23*25 is 575$

First, you replace c and d. You would end up with[tex]\frac{1}{4}[/tex] (6) + 3(7).
Then, you evaulate it. You end up with [tex]1\frac{1}{2}[/tex] + 21.
Lastly, you add them together. The final answer is [tex]22\frac{1}{2}[/tex].
Hi there!
Simplifly c and d:
c=6, d=7

Answer:
224 cm³
Step-by-step explanation:
Decompose the figure into two cuboid.
Volume of the bigger cuboid = L*W*H
L = 7 cm
H = 7 cm
W = 4 cm
Volume of the bigger cuboid = 7*7*4 = 196 cm³
Volume of smaller cuboid = L*W*H
L = 7 cm
W = 2 cm
H = 2 cm
Volume of smaller cuboid = 7*2*2 = 28 cm³
✅Volume of the figure = 196 cm³ + 28 cm³ = 224 cm³

Faucet A can fill up a water cooler in 8 minutes. Faucet B can fill the same water cooler in 12 minutes. How long will it take both faucets together to fill the water cooler?
!!!!!Explanation Needed!!!!!
Answer:
A cold water tap takes 3 minutes to fill the bath. A hot water tap takes 2 minutes to fill the bath. How long does it take to fill the bath when both taps are open at the same time?
It is easiest just to let the bath be a given size.
My little bath will be 12 litres
cold water 4L/min hot water = 6L/min
together 10L/1 min
10*(12/10) L per 1*(12/10) minutes
12L per 1.2min
12L per 1min and 12sec
It will take 1 minute and 12 seconds to fill the bath.
Step-by-step explanation:
Answer:
It will take 5 minutes for both faucets together to fill the water cooler
Step-by-step explanation:
I'm kinda just guessing but I do have a reasonable explanation
So the average time it takes for the faucets INDIVIDUALLY to fill the water cooler is 10 minutes
But since both faucets are filling them TOGETHER, it should take half the time
And half of 10 is 5
So it should take 5 minutes for both faucets together to fill the water cooler
If that makes sense

Fine the slope of the line perpendicular to the line graphed below
Answer:
[tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
The slope of this line is 2 because the rise from one point is 2, and the run is 1. The change in y-value is divided by the change in the x-value which is 2/1, hence, the slope of the line being 2.
The slope of the line perpendicular to the one shown below will be [tex]-\frac{1}{2}[/tex] because the slope that will result in a perpendicular line is the negative reciprocal of the original slope.
Marks own a carpet store and sells hallway runners for k9.52/linear foot. a) How much is this per linear yard? b) How much is the per linear Meter? C) Ralph needs 3.9m of the runner for his hallway. How much will it cost? Full working out. Please calculate this for me
Answer:
28.56/linear yard
32.2256/linear meter
121.77984k
Step-by-step explanation:
a) Scale = k9.52*3 = 28.56/linear yard
b) Scale = k9.52*3.28 = 32.2256/linear meter
c) Cost = 3.9 * 32.2256 = 121.77984k
solve for the missing angle measurement
The total sum of angles in a trapezium is 360°.
x + 80° + 75° + 105° = 360°
x + 260° = 360°
x = 360° - 260°
x = 100°
The missing angle measurement is 100°.
Hope it helps!
