Please help. I don't understand how to do number 14
murzikaleks [220]
This is quiet simple. i like to use a method my math teacher calls "plug and chug". we know that y= 4x +2
some people call this the substitution method but it has the same concept. now that we know what y equals, we plug it into teh equation:
(4x+2) -x=17
then we "chug it":
4x+2-x=17
then we have to isolate x. add the x's:
5x+2=17
in order to isolate x subtract 2 from both sides:
5x=15
now to isolate again divide both sides with 5:
x=3
so x is 3. bow we plug that into what y is;
y=4 (3) +2
y=14
so:
x=3
y=14
(to double check plug and chug into the first question . if x and y are correct, you will get 17)

What is the area of the button? Use 3.14 for π and round to the nearest tenth. The circumference of a button is 40.8 millimeters
Vika [28.1K]

Answer: radius = 6.5millimeters; Area = 132.7m²

Step-by-step explanation:

The circumference of a circle = 2πr

The area of a circle = πr²

The circumference of a button is 40.8 millimeters. Then we can get the radius, thus will be:

Circumference = 2πr

40.8 = 2 × 3.14 × r

40.8 = 6.28r

r = 40.8/6.28

r = 6.5

Radius is 6.5 millimeters

Area = πr²

Area = 3.14 × 6.5 × 6.5

Area = 132.7m²
