Anderson is a plumber and is paid a fixed amount just to make a house visit. The remainder of his fee, y, is determined by the n

Serhud [2]

Answer:

y=10x+50

Explanation:

The line starts at point (0,50) which is the y intercept (how much he gets paid to visit house).The line crosses points (10,150) and (20,250) and the slope of these points are 100/10 which when simplified equals 10x which is how much money he gets paid by the hour(x=hours) so y=10x plus the y intercept y=10x+50

(x - 2)² + 6x – 7 Which of the following is equivalent to

podryga [215]

Answer:

$x^2 +2x-3$

Step-by-step explanation:

Given

$(x - 2)\² + 6x - 7$

Required

The equivalent

We have:

$(x - 2)\² + 6x - 7$

Expand

$(x - 2)\² + 6x - 7 = x^2 -2x-2x +4 +6x - 7$

Collect like terms

$(x - 2)\² + 6x - 7 = x^2 -2x-2x+6x +4 - 7$

$(x - 2)\² + 6x - 7 = x^2 +2x-3$

Hence, the equivalent is:

$x^2 +2x-3$

If $-2 < x \le 3,$ then find all possible values of $5x + 1.$ Give your answer in interval notation PLEASE ANSWER THUS PLEASE

exis [7]

Answer:

$(-9,16]$

Step-by-step explanation:

we know that

The domain of x is equal to the interval--------> $(-2,3]$

$-2< x \leq 3$

All real numbers greater than $-2$ and less than or equal to $3$

Let

$y=5x+1$

For $x=3$

$y=5x+1\\y=5(3)+1=16$

For $x>-2$

$y >5(-2)+1\\y > -9$

so

The range of the function is the interval--------> $(-9,16]$

6x+2=-8+3x+25 whats the answer to x?

Nitella [24]

Answer:

x = 5

Step-by-step explanation:

To find the value of x make sure to get it on one side

First subtract 3x from each side. This makes the equation now

3x + 2 = -8 + 25

Now see what 25 subtract by 8 is (17)

3x + 2 = 17

Next subtract 2 from both sides

3x = 15

Lastly, divide 15 by 3, making x equal 5

x = 5
