Answer: (x, y) = (4, 1)

Step-by-step explanation:

1. Solve for y.

2(3y + 1) + 4y = 12

y = 1

2. Substitute the given value of y into the equation x = 3y + 1 and solve for x.

x = 3(1) + 1

x = 4

Answer:

x=4

y=1

Step-by-step explanation:

2(3y+1)+4y=12

6y+2+4y=12

10y+2=12

10y=10

y=1

Plug in 1 into y of the original equation

Ryan deposited $6,700 into an account at the Town Bank, earning 3.4% interest compounded annually. He made no deposits or withdr
Nonamiya [84]

Answer: The amount of money in his account after 4 years = $7,658.73

Step-by-step explanation:

If interest is compounded annually, then formula to compute amount :

A=P(1+r)^n, where P+ principal value, r= rate of interest, n= time ( in years).

As per given,

P= $6700 ,  r = 3.4% =0.034, n =4

A=6700(1+0.034)^4\\\\=6700(1.034)^4\\\\=6700(1.14309455234)\approx7658.73

Hence, the amount of money in his account after 4 years = $7,658.73

The variable Z is directly proportional to X. When X is 5, Z has the value 55.
LuckyWell [14K]
Z = k * x
55 = k * 5
divide both sides by 5
11 = x

z = 11x

z = 11 * 12
z = 132

-2x-y=-5 In slope intercept form please! :)
schepotkina [342]

Answer:

-2x - y = -5 in slop intercept form would be <u>y = -2x + 5 </u>

Step-by-step explanation:

-2x - y = -5

first add -2x to the left side to move it to the right side because whatever you do to one side u do to the other.

-y = -5 + 2x

divide by -1 on the whole equation

y = -2x + 5 is your answer.

What is the slope of a line with endpoints at (3,4) and (2,5)?
Lesechka [4]

\bf (\stackrel{x_1}{3}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{2}~,~\stackrel{y_2}{5}) \\\\\\ slope = m\implies \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{5-4}{2-3}\implies \cfrac{1}{-1}\implies -1

PLEASE ANSWER ASAP! SUPAH IMPORTANT! MUST BE CORRECT! POINTS GIVEN!
Dafna11 [192]

You said                                  -x + 8  >  6

Subtract 8 from each side:      -x        > -2

Add 'x' to each side:                 0        > -2 + x

Add  2  to each side:                      2  >  x

Now, test the choices:

     A).  Can 'x' be 4 ?
            No.  2  is not greater than  4 .

     B).  Can 'x' be  1 ?
           Yes.  2  is greater than  1 .

     C).  Can 'x' be  2 ?
            No.  2  is not greater than  2 .

     D).  Can 'x' be  15 ?
            No.  2  is not greater than  15 .
