Answer:

B (4, 9)

Step-by-step explanation:

Isolate one of the variable on the first equation

5 = -x + y

turn to

x = y - 5

Then insert this into the second equation

3 = 3(y - 5) - y

Simplify-

3 = 3y - 15 - y

3 = 2y - 15

Add 15 to both sides

18 = 2y

Divide by 2

9 = y

knowing y = 9 you can assume that -

(x, 9)

This means the only possible answer is B

Graph the function <br> Is it a, b, c or d?
Jobisdone [24]

Answer:

D

Step-by-step explanation:

(the line is a / shape, so the slope is positive)

(the line crosses the y axis at (0,-2))

(using the above information, we can conclude that the equation is y=2x-2)

or

slope = m = rise/run = 2/1 = 2

y=mx+b

y=2x+b

Choose any point on the line) (1,0)

0=2(1)+b

b=-2

y=2x-2

What is the value of the expression “three less than the quotient of ten and a number, increased by six” when n = 2?
alisha [4.7K]

Answer:

8

Step-by-step explanation:

The given expression is "three less than the quotient of ten and a number, increased by six”

The quotient of ten and a number increased by six is translated into mathematical expression as:

\frac{10}{n}+6

Three less than the quotient of ten and a number, increased by six is

(\frac{10}{n}+6)-3

When we substitute n=2, we get:

(\frac{10}{2}+6)-3

Divide to get:

(5+6)-3

Add to get:

11-3

Subtract
