How to solve the equation

Mathematics
1 answer:
wariber [46]3 years ago
5 0
Hey there!

So it's mentioned that the line is parallel, hence their gradient are equals.

From the eqn, y = 2x + 1 , you'll find that the gradient is 2 (conveniently, the equation of the line is directly derived from y=mx+c, where m is the gradient.)

Using the coordinates (2, -1) as the line passes through those points, make a new equation (with y=mx+c) with those points and the gradient 2 in order to find constant c.

-1=(2)(2) + c
c=-5

hence, the equation is y=2x-5.

The whole working is actually very short so I hope I didn't overcomplicate things :(

Last year, Americans paid $2.00 per gallon of gas. This year, the price is $2.40 per gallon. What is the percent of change in th
xxTIMURxx [149]
So it's 2.40 subtract 2, which is 0.4

then put it over 2, you get 0.4/2, which is equal to 0.2

0.2= 20% so it's 20% of increase

What scale factor was used in going from the grey triangle to the yellow triangle?
Lena [83]

Answer:

2

Step-by-step explanation:

First, we need to find out the length of the third side of the triangle. (The right side of the Y-axis) We use the pythagorean theorem to find it. 4²+2² = 20 find the square root of 20 √20 = ~4.5 so with this in mind, lets find the length of the whole triangle. 8²+4²=80 then √80 = ~9 with this, we can say that since the length of one of the legs has increased by 2, and so has the length of the base, and also the length of the hypotenuse, the scale factor must be 2.

13.) Solve for M<br> 14.) Solve for A<br> 17.) Solve for H
brilliants [131]

Answer:

See Below (Isolate the variables)

Step-by-step explanation:

13) d = 4AM solve for M

Divide both sides by 4A

\frac{d= 4AM}{4A}

\frac{d}{4A} = M

14) \frac{A}{6} = f+h  solve for A

Multiply both sides by 6

A = 6( f+h)

15) h - m = qb solve for H

Add m to both sides

h - m = qb

  + m   +m

h = qb + m

Find L when P= 24 and W = 6.<br> P = 2L+ 2W (perimeter of a rectangle)<br> L =
Anon25 [30]

Answer:

6

Step-by-step explanation:

24 = 2L + 2(6), multiply...

24 = 2L + 12, subtract 12 to both sides...

12 = 2L, divide 2 to both sides to isolate the varibale L

6 = L

Therefroe, L = 6
