What is the equation of a line that contains the points (2,-2) and (0, -2)?
Zolol [24]

Answer:

y = - 2

Step-by-step explanation:

The equation of a horizontal line parallel to the x- axis is

y = c

Where c is the value of the y- coordinates the line passes through

The line passes through (2, - 2) and (0, - 2) both with y- coordinate of - 2, thus

Equation of line is y = - 2

Keisha, Scott, and Ryan have a total of $101 in their wallets. Keisha has $6 more than Scott. Ryan has 3 times what Scott has. H
Yuri [45]

Answer:

Keisha =$25

Scott =$19

Ryan = $57

Step-by-step explanation:

Let the amount each have be represented by A, B and C

Keisha = A

Scott = B

Ryan = C

Keisha , Scott and Ryan have a total of $101.

That’s

A + B + C = $101

Keisha has $6 more than Scott

A = 6 + B

Ryan has 3 times Scott

C = 3B

Substitute 6+B for A and 3B for C in the first equation.

That’s

A + B + C = 101

6 + B + B + 3B = 101

6 + 5B = 101

Subtract 6 from both sides

6 - 6 + 5B = 101 - 6

5B = 95

Divide both sides by 5

B = 95/5

B = 19

Scott has $19

Recall Keisha has $6 more than Scott B.

That’s A = 6 + B

A = $6 + $19

A = $25

Keisha has $25

Also, Ryan C has 3 times what Scott B has .

That’s

C = 3 x B

C = 3 x 19

C = $57

Therefore, Keisha has $25, Scott has $19 and Ryan has $57

Age at BBM 2019 Question Group 'A Brief answer questions; 1. Integrate the following: S(ax? + 2bx + c)3/2(2xa + 2b) dx 2.
worty [1.4K]

If the integral is

\displaystyle \int (ax^2+2bx+c)^{3/2}(2ax+2b)\,\mathrm dx

substitute u = ax^2+2bx+c and \mathrm du=(2ax+2b)\,\mathrm dx. Then you end up with

\displaystyle \int u^{3/2}\,\mathrm du = \frac25u^{5/2} + C

which in terms of <em>x</em> is

\boxed{\dfrac25(ax^2+2bx+c)^{5/2} + C}
