Answer:   $195

Step-by-step explanation:

Let x be the amount of money (in dollars) saved by Brett.

Then, the amount saved by Dan = 2x

The amount saved by Maria = 60+x           (1)

If they saved $600 altogether, then we have the following equation :-

x+2x+x+60=600\\\\\Rightarrow\ 4x=600-60\\\\\Rightarrow\ 4x=540

Divide both sides by 3, we get

x=135

Now, the amount saved by Brett = $135

The amount saved by Maria = $135+$60 = $195     [From (1)]

Setting it up, we have Dan + Bret + Maria all saving 600.00
Dan = 2B
Bret = B
Maria = B+60

2B + B + B + 60 = 600
4B = 540
B = 135

Dan = 2(135) = 270
Brett = 135
Maria = 135 + 60 = 195

Which of the fallowing points are the solution to the equation 3x-4y-8=12. Chose all that apply (0,-5) (4,-2) (8,2) (-16,-17) (-
Virty [35]

Answer:

The solutions for the equation are:

(4,-2) and (-16,-17)

Step-by-step explanation:

Given equation:

3x-4y-8=12

Given points:

(0,-5), (4,-2), (8,2), (-16,-17), (-1,-8), (-40,-34)

We will check each point by plugging it in the given equation and see if it satisfies the equation or not.

(0,5)

3(0)-4(5)-8=12

0-20-8=12

-28=12

which is not true. Hence, not a solution.

(4,-2)

3(4)-4(-2)-8=12

12+8-8=12

12=12

which is true. Hence, it is a solution.

(8,2)

3(8)-4(2)-8=12

24-8-8=12

24-16=12

8=12

which is not true. Hence, not a solution.

(-16,-17)

3(-16)-4(-17)-8=12

-48+68-8=12

20-8=12

12=12

which is true. Hence, it is a solution.

(-1,-8)

3(-1)-4(-8)-8=12

-3+32-8=12

21=12

which is not true. Hence, not a solution.

(-40,-34)

3(-40)-4(-34)-8=12

-120+136-8=12

8=12

which is not true. Hence, not a solution.

The equation of line CD is y = −2x − 2. What is the equation of a line parallel to line CD in slope-intercept form that contains
aniked [119]

Answer:

\[y=-2x+13\]

Step-by-step explanation:

Equation of the line CD is given as \[y=-2x-2\]

Slope of the line CD = -2

Slope of the line parallel to CD = -2

Equation of the line parallel to CD is given by \[y=mx+c\]

\[y=-2x+c\]

But this line passes through (4,5)

Substituting the values in the equation:

\[5=-2*(4)+c\]

=> \[c=5+8=13\]

So the overall equation of the parallel line is given by \[y=-2x+13\]

Answer:

x=5    x = -3

Step-by-step explanation:

-7 / ( x^2 -2x -15)

Factor the denominator

-7

----

(x-5) ( x+3)

The excluded values are when the denominator is equal to zero

(x-5) (x+3) =0

x-5 =0   x+3=0

x=5    x = -3
