Answer: y = (7/4)x - 3
Step-by-step explanation:
m = (-10 - (-3))/(-4 - 0) = -7/(-4) = 7/4
y-intercept = (0, -3)
y = (7/4)x - 3

4(r + 20) = 1/5(20r + 400)
Answer:
r = r
Step-by-step explanation:
4(r + 20) = 1/5(20r + 400)
4r + 80 = 4r + 80
- 80 - 80
4r = 4r
4 4
r = r
Answer:
no solution
Step-by-step explanation:
4(r + 20) = 1/5(20r + 400)
4r + 80= 4r+ 80
-4r -4r
80= 80

What is the equation of a line that is perpendicular to the line y = 2x + 4 and passes through the point (-2, 3)?
Answer:
[tex]y=-\frac{1}{2} x+2[/tex]
Step-by-step explanation:
The given equation is written in slope-intercept form:
[tex]y=mx+b[/tex]
where:
m is the slopeb is the y-interceptx and y are the corresponding coordinate points (x,y)The slope is 2:
When two lines are perpendicular, their slopes will be opposite reciprocals. Find the slope of the line perpendicular to the given equation:
[tex]m_{1}=2[/tex]
This can be seen as:
[tex]m_{1}=\frac{2}{1}[/tex]
Flip the fraction (reciprocal):
[tex]\frac{2}{1}[/tex] → [tex]\frac{1}{2}[/tex]
Now find the opposite:
[tex]\frac{1}{2}[/tex] → [tex]-\frac{1}{2}[/tex]
So the slope of the perpendicular line is:
[tex]m_{2}=-\frac{1}{2}[/tex]
Now make an equation written in point-slope form:
[tex]y-y_{1}=m(x-x_{1})[/tex]
where:
m is the slope[tex]x_{1}[/tex] and [tex]y_{1}[/tex] are the corresponding coordinate points [tex](x_{1},y_{1})[/tex]Insert information:
[tex]y-3=-\frac{1}{2} (x-(-2))\\\\y-3=-\frac{1}{2} (x+2)[/tex]
Simplify to slope-intercept form. Solve for y:
Use the distributive property:
[tex]y-3=-\frac{1}{2}(x)-\frac{1}{2} (2)\\\\ y-3=-\frac{1}{2} x-1[/tex]
Add 3 to both sides to isolate the variable:
[tex]y-3+3=-\frac{1}{2} x-1+3\\\\y=-\frac{1}{2} x+2[/tex]

sum of two integers is -30 if one of them is 15 find the other integer pls urgent will mark u the brainliast
Answer:
-45
Step-by-step explanation:
Sum of two integers = -30
one of them = 15
let another number be 'x'
x + 15 = -30
x = -30 - 15
x = -45
so the other number is -45

How much carpet would you need in square feet to cover a floor with dimensions of 12 feet by 15 feet?
Answer:8
Step-by-step explanation:
Area = Length x Width.
simple room measurement
Measure the length using the distance from one wall to the opposite wall.
Measure the width from wall to wall.
Add 2 to 4 inches to each side. This accounts for waste, doors and slanting walls. It’s easy to cut a little off for a perfect fit, but it’s impossible to add without creating unsightly seams.
Multiply the length times the width or enter those into the calculator above. This is your total square footage for that room.
Repeat this process for each room.

sin(2x) = cos(x)cos(x) – sin(x)sin(x)
sin(2x) = sin(x)cos(x) – sin(x)cos(x)
sin(2x) = cos(x)cos(x) + sin(x)sin(x)
sin(2x) = sin(x)cos(x) + sin(x)cos(x)
Answer:
The correct answer is D) sin(2x) = sin(x)cos(x)+sin(x)cos(x)
Step-by-step explanation:
Right answer on Edge
The step 2 will be;
⇒ sin (2x) = sin (x) sin (x) + cos (x) cos (x)
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The steps are;
Step 1; sin (2x) = sin (x + x)
Step 3; sin (2x) = 2 sin (x) cos (x)
Now,
Since, The steps of the solution are;
Step 1; sin (2x) = sin (x + x)
Step 3; sin (2x) = 2 sin (x) cos (x)
Hence, We get;
All the steps as;
⇒ sin (2x) = sin (x + x)
⇒ sin (2x) = sin (x) sin (x) + cos (x) cos (x)
⇒ sin (2x) = 2 sin (x) cos (x)
Thus, The expression for step 2;
⇒ sin (2x) = sin (x) sin (x) + cos (x) cos (x)

A train goes at a constant speed. If it covers 150 miles in 2 1 2 hours,
What distance would it cover in 7 hours?
Answer: I think is 420 miles in 7 hours
hope this helps :D
Step-by-step explanation:
Answer:
A train would cover 180 miles in 3 hours, So in 6 hours it will cover 360 miles, in 7 hours it will cover 420 miles.
Step-by-step explanation:
150 miles → 2 1/2 hours = 150 minutes
x miles → 3 hours = 180 minutes
(150 × 180) ÷ 150 = x miles
27,000 ÷ 150 = x miles
180 = x miles

To boil rice, start by combining water and rice in a pot at a ratio of 3:1. How many cups of water are need for a batch that uses eight cups of rice?
Answer:
Step-by-step explanation:
To boil rice you use the following ratio
Water : Rice
3 : 1
? : 8
Basically what the ratio 3:1 means is that for every 3 cups of water, you need 1 cup if rice.
6 cups of water, you need 2 cups of rice (6:2)
9 cups of water, 3 cups of rice (9:3)
Etc.
All you would have to do is multiply 3 by 8 to find out how much water she needs for 3 cups of rice :)
Answer:
ok the ratio of water to Rice is 3:1 meaning water is 3 rice is one and your child that we have 8 cups of rice so really quite the ratio of rice to the number of cups of rice so it will be if one is equals to 8 what about 3 that is the ratio that represents water so we'll cross multiply so that you have 3 * 8/1 and the answer is 24 so the number of cups of water needed is 24

If two lines are parallel and the slope of one of the lines is M, what is the product of their slopes? *
2 points
1
2M
M²
-1
Thanks will mark brainliest
Answer:
M²
Step-by-step explanation:
Parallel lines have equal slopes.
One line has a slope of M then the line parallel to it has a slope of M , thus
product of slopes = M × M = M²
The the product of their slopes is M².
What is slope?A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,
m = Δy/Δx
where, m is the slope
Given:
two lines are parallel
and the slope of one of the lines is M
Also, the parallel lines have the same slope.
So, both the line lines have slope M.
Now, the the product of their slopes
= M x M
= M²
Hence, the product of their slopes is M².
