Answer: A and D

Step-by-step explanation:

To find the line that is parallel to the given line, we must find the slope of the original. Parallel lines NEVER touch or cross. That tells us the slope MUST be the same. To find the slope, we use the formula y=\frac{y_2-y_1}{x_2-x_1}.

y=\frac{4-0}{0-(-1)} =\frac{4}{1} =4

With the slope, we can form an equation for the line.

y=4x+b            [plug in given point]

0=4(4)+b         [multiply]

0=16+b            [subtract both sides by 16]

b=-16

Now that we have the y-intercept, we can find the equation.

y=4x-16

After plugging in each point into the equation, we know that A and D are correct points on the line.

There are a total of 66 students in the
attashe74 [19]

Answer:

A = 26

Step-by-step explanation:

sum of students = classA + classB + classC

let's say classA = A, classB = B, and classC = C

A + B + C = 66

class A has five more students than class B, so A = 5 more than B so A = 5+B

class C has 2 less students than class B, so C = 2 less than class B = B -2, so C = B-2

A + B + C = 66

A = 5+B

C = B-2

substitute 5+B for A and B-2 for C in the first equation to limit this to one variable (B)

(5+B) + B + (B-2) = 66

3B + 3 = 66

subtract 3 from both sides to isolate the variable and its coefficient

3B = 63

divide both sides by 3 to solve for B
B = 21

A = 5 + B = 5 + 21 = 26

A student writes "the quotient of 5 and x" to describe the algebraic expression -
pashok25 [27]

For this case we have to:

\frac {a} {b} = c

Where:

a: It's the Dividend

b: It is the Divider

c: Is the Quotient

Thus, the expression "the quotient of 5 and x" can be represented as:

\frac {5} {x} = y

Where "y" is the quotient of 5 and x.

ANswer:

\frac {5} {x} = y

I am a rectangle, and my area is 80 square inches. My width is 2 inches shorter than my length. What is my perimeter?
pshichka [43]
Area=l*b=l*(l-2)=80(given)

so, l^2 - 2l =80
   l^2 - 2l - 80=0
   l=10 or -8

l=10,b=10-2=8
perimeter=2(l+b)=2(18)=36
