No, 5 times 3 is 15. 5/3 is 1.66 (repeating)
Cross multiply your fractions. if you have x/3=5/7, x*7 has to equal 3*5, meaning 7x=15. divide both sides by seven to get x=7/15.
Answer:
<h2>slope = 2</h2>
Step-by-step explanation:
The formula of a slope:

We have

Substitute:

y=x^2 - 10x +2
Use the form ax^2 + bx + c to find the values of a, b,and c.
a = 1 ( no number in front of the x^2)
b = 10
c = 2
Vertex form is a(x+d)^2 + e
Solve for d using d= b/2a
d = 10 / 2
d = 5
Find e using e = c - b^2/4a
e = 2 - 10^2/4
e = 2 - 25
e = -23
Vertex = d,e
Vertex = (5, -23)
