It would be be the first solution, as it follows the format of (y y1) = m(x-x1)

we know that

the equation of the line into point-slope form

is equal to

$y-y1=m(x-x1)$

in this problem we have the point

$(x1,y1)=(-10,8)$

substitute in the formula

$y-(8)=m(x-(-10))$

$y-8=m(x+10)$

therefore

the answer is

$y-8=-0.2(x+10)$

James and Lin got married and got new jobs. Lin earns $3100 more per year than James. Together they earn $81,980. How much does

Bumek [7]

Answer:

The earning to James per year is $ 39,440

The earning of Lin per year is $ 42,540 .

Step-by-step explanation:

Given as :

The total earning of James and Lin together = $ 81,980 per year

The earning of Lin is $ 3100 more per year than James

Let The earning of James = $ J

And The earning of Lin = $ J + $ 3100

So, According to question

The total earning of James and Lin together = $ 81,980 per year

Or, The earning of Lin + The earning of James = $ 81,980 per year

Or, $ J + $ 3100 + $ J = $ 81,980 per year

or, 2 $ J = $ 81,980 - $ 3100

Or, 2 $ J = $ 78880

∴ J = $\frac{78880}{2}$

I.e The earning to James per year = $ 39,440

And The earning of Lin per year = $ 34,440 + $ 3100 = $ 42,540

Hence, The earning to James per year is $ 39,440

And The earning of Lin per year is $ 42,540 . answer

Solve for n -19=-8+n

laila [671]

-------------------------------------------------------------------------------------------------------------

Answer: $\textsf{n = -11}$

-------------------------------------------------------------------------------------------------------------

Given: $\textsf{-19 = -8 + n}$

Find: $\textsf{Solve for n}$

Solution: In order to solve for n we need to add 8 to both sides which would cancel -8 on the right side and isolate n giving us the value of n.

Add 8 to both sides

$\textsf{-19 + 8 = -8 + 8 + n}$

$\textsf{-19 + 8 = n}$

$\textsf{-11 = n}$

Therefore, the final answer would be that n is equal to -11.

A car was sold 24 standard washed in a day , which was 25% of their total sales for that day . What was the total amount of wash

-Dominant- [34]

Answer:

$96$

Step-by-step explanation:

GIVEN: A car was sold $24$ standard washed in a day , which was $25\%$ of their total sales for that day.

TO FIND: Total amount of washes that the car wash sold that day.

SOLUTION:

Let the total sales of car washes sold for that day $=x$

total number of standard car washes sold $s=24$

As, total standard car washes sold are $25\%$ of total sales in a day

$s=\frac{25}{100}x$

putting value in equation

$24=\frac{25}{100}x$

$x=\frac{24}{25}\times100$

$x=96$

Hence the total number of car washes sold that day are $96$

adult tickets to the fall play cost $8 and student tickets cost $4. the drama class sold 20 more adult tickets than student tick

andriy [413]

let us repersent the number of student tickets, then 's + 20' is repersenting the number of adult tickets.

The equation for the total tickets can be experssed as the following:

4.00 * s + 8.00 * ( s + 20 ) = 880.00

solving for 's=60', there were 60 student tickets.

60 + 20 = 80

there were 80 adult tickets.

Hope helps!-Aparri
