Answer:

(2, -2)

Step-by-step explanation:

First, you make 2 equations.

-6 + x = -4 (The -6 is from point A and the -4 is from point M)

3 + y = 1 (The 3 is from point A and the 1 is from point M)

Then you subtract -6 from each side of the first equation and subtract 3 from each side of the second equation.

You should get:

x = 2

y = -2

You plan to go snowboarding. The resort charges $15 an hour in addition to $25 to rent a board. Write an equation that represent

sladkih [1.3K]

Answer:

6 Hours

Explanation:

Linear Equation: mx+b=y

x variable: Hour

Hourly Fee: $15(x)

(Initial) Rent Fee: $25

Balance: $100

Equation:

15x+25=100

15x+25-25=100-25 -- Separate the constant terms from the x by subtracting 25 from both sides.

15x=100

15x/15=100/15 -- Isolate the x variable by dividing 15 from both sides.

x=6.6.. -- Round down to 6 (not 7) because you can't afford to snowboard for 7 hours with less than $15.

x=6 Hours

In a test (+5) marks are given for every correct answer and (-2) marks are given for every incorrect answer. Smitha answered all

Ymorist [56]

Answer:

15 answers

Step-by-step explanation:

To solve this question we need to set up an equation.

Let's name the number of incorrect answers x.

We can set up an equation that's essentially:

(Points for correct answer)*(number of correct answers)+(points for incorrect answer)*(number of incorrect answers)=final score

When we plug in our numbers and variables it looks like this:

5(3)+(-2x)=-15

Simplify

15-2x=-15

Subtract 15 from both sides

-2x=-30

Divide both sides by -2

x=15

This means Smitha attempted 15 wrong answers, and that there were 18 questions in total.

the dimensions of a rectangle can be expressed as x-3 and x+8. If the area of the rectangle is 42 square feet. Find the dimensio

nasty-shy [4]

We know that
the area of a rectangle=length*width
let
length=x-3
width=x+8
area=42 ft²
so
42=(x-3)*(x+8)----------> x²+8x-3x-24=42--------> x²+5x-66=0

using a graph tool-------> to resolve the second order equation
see the attached figure
the solution is
x=6
hence

length=x-3------> 6-3-----> 3 ft
width=x+8 ------> 6+8----> 14 ft

the answer is
the dimensions of the rectangle are 3 ft x 14 ft
