Answer:

x =2

Step-by-step explanation:

for this problem your solving for x so to do that you have to get it alone

so subtract 15 by both sides --> 3 -15 = -6x +15-15

getting --> -12 = -6x

now divide by -6 by both sides getting x = 2

Answer: x = 2

Step-by-step explanation:

3= -6x +15

Step 1: make x the subject

-6x= 3-15

-6x= -12

Step 2: Divide both sides by -6 to get the value of x;

x= -12/-6

x=2

Plug in x =2 into the initial equation:

3= -6(2) +15

3= -12 +15

x = 2 is the correct answer

Step-by-step explanation:

(a)Mortgage = 332000 - 42000 = 290000

15 * 12 = 180 months

Total monthly payments = 180 * 2447.19 =440494.2

Total = 440494.2 + 42000 = 482494.2

I'm having trouble figuring out what the equation is for the trend line and what the slope is
Talja [164]

Answer:

The equation for the trend line would be y = -1/100x + 25

Step-by-step explanation:

In order to find the trend line, we first need to find the slope. To do so, we need to find two points on the line. The points we'll use are (0, 25) and (2500, 0). Next, we use the slope formula.

m(slope) = (y2 - y1)/(x2 - x1)

m = (0 - 25)/(2500 - 5)

m = -25/2500

m = -1/100

Now that we have this we can use the slope and the intercept in slope intercept form to model the trend line.

y = mx + b

y = -1/100x + 25

4(3x+5)= -4
NeX [460]

Answer/explanation

4(3x+5)=-4

You will distribute the four to every term in the parenthesis,

12x+20=-4

Then you will combine like terms

12x+20=-4

     -20  -20

12x=-24

Then you will divide 12 to isolate x

\frac{12x}{-24} =\frac{-24}{-24}

Obviously, -24 cancels out and you would get x=-2
