Write the equation of a line with a slope of 4 and a y-intercept of −3. 4x + y = −3 4x – y = −3 y = −3x + 4 y = 4x − 3

Answers

Knowing the slope and y-intercept of a line you can put its equation in slope-intercept form.
The slope-intercept form equation of a line is $y=mx+b$ where $m$ is the slope and $b$ is the y-intercept.
In this case, since the slope is 4 and the y-int. is -3, our equation must be
$\boxed{y=4x-3}$

y=4x-3

4 is the slope and -3 is the y intercept

By plugging these values into the slope intercept form: y=mx+b I came up with the previous answer-y=4x-3

m= the slope, and b=the y intercept

students?

1. 12

4. 15

Answers

Answer is 4.) 15 girls.

If you go 27-5-4=18
18-5-4=9
9-5-4=0
so 5+5+5 (because it's 5 girls to 4 boys, only count the 5's) =15

Hope this helps! :)

Four hundred vouchers were sold for a carwash. Vouchers to wash trucks were $4, while vouchers to wash compact cars were $3. If the total sales were $1350, how many of each type of voucher were sold?

Answers

Answer:

150 vouchers to wash trucks were sold

250 vouchers to wash compact cars were sold

Step-by-step explanation:

Here, we are interested in calculating the number of each type of vouchers sold.

Let the number of vouchers to wash trucks be x while the number of vouchers to wash compact trucks be y.

Firstly, we know that both sums up to be 400.

Mathematically;

x + y = 400 •••••••••(i)

Secondly,

since a voucher to wash trucks sell $4, and we sold a total of x, the amount generated from selling is 4 * x = $4x

Same way for the vouchers to wash compact cars, we have a total of $3 * y = $3y

The sum of both gives $1350, which is the total sales.

Mathematically;

4x + 3y = 1350 ••••••(ii)

So we have two equations to solve simultaneously;

x + y = 400

4x + 3y = 1350

Multiply equation i by 4 , we have;

4x + 4y = 1600

4x + 3y = 1350

Subtract equation ii from i, we have 4y-3y = 1600-1350

y = 250

From equation 1, we know that

x + y = 400

This means that;

x = 400 -y

x = 400 -250

x = 150
