Answer:

Connect points A and B. That makes a line parallel to the y-axis and perpendicular to the x-axis. Plot two more random points and write down their coordinates along with points A and B's coordinates. For number 5, it says that the point you need to write has to fall on line L with a y-coordinate greater than 20. Coordinates (x,y) y has to be greater than 20 and x has to be equal to 4. So (4, any number over 20) would work. For example: (x, 25) would be an appropriate answer to number 5. Hope this helps!

Mae Ling earns a weekly salary of $315 plus a 5.5% commission on sales at a gift shop. How much would she make in a work week if

Alecsey [184]

She would make $573.5 in a work if she sold $4,700 worth of merchandise

Step-by-step explanation:

The given is:

Mae Ling earns a weekly salary of $315 plus a 5.5% commission on sales at a gift shop
She sold by $4,700

We need to find how much she would make in a work week

∵ Mae Ling earns a weekly salary of $315

∵ She earns a 5.5% commission on sales

∵ She sold by $4,700 in that week

- Add $315 to the product of 5.5% and $4,700

∴ She made = 315 + (5.5% × 4,700)

∵ 5.5% = 5.5 ÷ 100 = 0.055

∴ She made = 315 + (0.055 × 4,700)

∴ She made = 315 + 258.5

∴ She made = 573.5

She would make $573.5 in a work if she sold $4,700 worth of merchandise

Consider the equation of parabola y = 5x - 30x + 45.

VARVARA [1.3K]

Answer:

(3, 0 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c (a ≠ 0 )

Then the x- coordinate of the vertex is

$x_{vertex}$ = - $\frac{b}{2a}$

y = 5x² - 30x + 45 ← is in standard form

with a = 5, b = - 30 , then

$x_{vertex}$ = - $\frac{-30}{10}$ = 3

Substitute x = 3 into the function for corresponding value of y

y = 5(3)² - 30(3) + 45 = 45 - 90 + 45 = 0

vertex = (3, 0 )

If y = -252 when x = 84, what is y when x = 74

MAVERICK [17]

If x =1 y = ?

y = -252/84
y = -3
y = -3*74
y = - 222

we need to calculate the value of y when x =1
we have to divide the value of y by value of x by doing this we can get the value of y is -3 when x=1
when x = 74 we have to multiply the value of x & y (74 *-3)
so the answer is -222
