Answer:

1.What is the y intercept of the function?

y-coordinate when x = 0, take from the table.

(0, 5)

2.What is the first difference?

Difference of y-values. This is the slope

7-5 = 2

3.Write an equation to represent the function given in the table

Use the first difference and the y-intercept: b = 5, m = 2

y = 2x + 5

Your meal cost $72.15 including the 11% tax. What was the original cost of your meal before tax?

Amiraneli [1.4K]

Multiplying 72.15 by .11 or 11% gives you 7.94 - this is the tax taken.
so just subtracting that from 72.15 gives you $64.21 as your answer.

Can y’all help me plss

Troyanec [42]

In a parallelogram,

⇒the angles adjacent to each other

⇒ are of the same measure

⇒so

∠A = ∠C

∠B = ∠D

Let's solve:

∠A = ∠C

$7z +5 = 8z - 10\\5+10=8z-7z\\8z-7z=5+10\\z = 15$

∠B = ∠D

$5w-30=3w+10\\5w-3w=30+10\\2w = 40\\w=20$

Let's check:

⇒ for all quadrilaterals like a parallelogram

⇒all the angle measures added up to 360, so:

$(7z+5)+(8z-10)+(5w-30)+(3w+10)=360\\(7(15)+5)+(8(15)-10)+(5(20)-30)+(3(20)+10)=360\\(105+5)+(120-10)+(100-30)+(60+10)=360\\110+110+70+70=360\\220+140=360\\360=360$

Thus:

Answer: w = 20 and z = 15

Hope that helps!
