4. Two points on a line are (-10, 1) and (5, -5). If

Vsevolod [243]

Answer:

The x-coordinate of another point is zero

Step-by-step explanation:

step 1

Find the slope between the two given points

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$(-10,1),(5,-5)$

substitute in the formula

$m=\frac{-5-1}{5+10}$

$m=\frac{-6}{15}$

Simplify

$m=-\frac{2}{5}$

step 2

Find the x-coordinate of another point

we have

(x,-3)

we know that

If the other point is on the line, then the slope between the other point and any of the other two points must be the same

Find the slope between the points

$(x,-3),(5,-5)$

Remember that

$m=-\frac{2}{5}$

substitute in the formula

$-\frac{2}{5}=\frac{-5+3}{5-x}$

$-\frac{2}{5}=-\frac{2}{5-x}$

the denominators must be the same

$5=5-x$

$x=0$

therefore

The x-coordinate of another point is zero

jacob just had lunch at a restaurant and leaves a 18% tip. Choose all the expressions that will give his total cost in terms of

Leokris [45]

Answer:

1.18b

Step-by-step explanation:

Jacob had lunch at a restaurant and his bill was b.

Now, Jacob leaves 18% of his bill amount as a tip.

So, the tip amount at the rate of 18% of the bill amount will be $\frac{18 \times b}{100} =0.18 \times b$

Therefore, the total cost of Jacob for the lunch will be b + 0.18b = 1.18b. (Answer)
