HELP ME PLEASE PLEASE

Mathematics
1 answer:
Ymorist [56]3 years ago
6 0

Answer:

The value of x is 7 and y is 14.

Step-by-step explanation:

The steps are :

- 3x + y =  - 7 -  -  - (1)

y = x + 7 -  -  - (2)

(2)→(1)

- 3x + (x + 7) =  - 7 \\  - 3x + x + 7 =  - 7 \\  - 2x =  - 14 \\ x = 7

substitute \: x = 7 \:  \: into \:  \: (2)

y = 7 + 7 \\ y = 14

20 POINTS!!!! <br> HELPPPPP THIS IS DUE TONIGHT!!!!
alexandr1967 [171]

Step-by-step explanation:

Our coordinates are (6, 0) and (0, -3).

We can use the formula (y₂-y₁)/(x₂-x₁) to find the slope-intercept form (y=mx+b)

Now, we plug the coordinates into the formula and solve.

(0-(-3))/(6-0)

=3/6

=\frac{1}{2}

So, the slope is \frac{1}{2}.

Now, we have to find the y-intercept, which is the point where the line on the graph intersects with the y-axis.

We can find the y-intercept (which is represented by b) by plugging the information we already know into the formula.

We can use either pair of coordinates for the formula, so I'll use (6, 0).

y=mx+b

0=\frac{1}{2}(6)+b

Now, we can solve.

0=3+b

Subtract 3 from both sides.

-3=b

The y-intercept is -3.

Answer:

y=\frac{1}{2}x-3

Which statement is generally true about retirement?
nexus9112 [7]

The general statement that is true about retirement is <em>B. your </em><em>income </em><em>will decrease, while your </em><em>expenses </em><em>will increase.</em>

Retirement is the leaving of one's of occupation. This means you cease to be involved in active service in a job or occupation especially when one is considered old and of retirement age.

During retirement, retirement benefits and pension are usually made available to retirees. However, one's income will come to a decline which makes most people scared of retirement. Keeping up with the standard of living they are used to becomes difficult as income to sustain such may not be available.

Therefore, the general statement that is true about retirement is <em>B. your </em><em>income </em><em>will decrease, while your </em><em>expenses </em><em>will increase.</em>
