MARKING BRANLIEST!! PLEASE HELP!!! what are the x-intercepts of the quadratic function y=x^2-3x+2
enot [183]
X-intercepts are points where the graph intersects the x-axis, i.e. when y=0.

Substitute y=0 and solve for x:
y=x^2-3x+2
0=x^2-3x+2
0=(x-2)(x-1)

By the zero product property, we deduce x-2=0 or x-1=0, i.e. x=1 or x=2.

4/5 of a class is girls and there are 8 boys. How many total in class.
Ann [662]

Answer:

40

Step-by-step explanation:

a+b=c

a=girls

b= boys

c= total

the statement tell us:

4/5 of a class is girls:

a=(4/5)*c

boys=b=8

c=a+b

so we have:

c=(4/5)*c + 8

c-(4/5)*c=8

(5c-4c)/5 = 8

c/5=8

c=8*5

c=40

total=40

Please help! I’m very confused on this question. I’m not very good at geometry.
Ahat [919]

Well, to find the perimeter we have to add all of the side lengths, so let's do that:

2x+3 +2x+3 +2x

And we know that this equals 36 so let's solve for x

2x+3+2x+3+2x = 36

6x+6 = 36

6x = 30

x = 5

So we know know that x = 5.

Now all you have to do is plug in the values of x into the lengths

2(5) + 3

= 10+3

= 13 is the length of two of the sides.

2x

= 2(5)

= 10

And 10 is the length of the last side.
