Hack
for y=ax^2+bx+c
the xvalue of the vertex is -b/2a
and the y value is found by subsituting that for x

so

-b/2a

h(t)=2x^2+4x+7
a=2
b=4
-b/2a=-4/(2*2)=-4/4=-1
the y value
h(-1)=2(-1)^2+4(-1)+7
h(-1)=2(1)-4+7
h(1)=2+3
h(1)=5

(-1,5) is da vertex

Evaluate 5a+3b and (5+a)(3+b) for a=2 and b=4. How is the order of the steps different for the two expressions?
Lynna [10]
5a+3b
5(2)+3(4)
10+12
22

(5+a)(3+b)
(5+2)(3+4)
(7)(7)
49

The order of the steps differ for the two expressions because for the first expression, you multiply 5a and 3b first. Then, you add them together. However, for the second expression, you add what's inside the parenthesis first then multiply them. So, the order of the steps is the opposite of the other expression.

Hello!

It tells you what to do in the question

First round all the numbers to the nearest whole number

2.20 = 2
2.34 = 2
2.7 = 3

Then it says to multiply all the numbers

2 * 2 * 3 = 12

Then it says to divide by 6

12 /  6 = 2

The answer is 2 cubic yards

Hope this helps!

Use the diagram to complete the statement.
Dima020 [189]

Answer:

∠FJH ≅ ∠BJA

Step-by-step explanation:

From the image we can see that the only congruent relation ∠FJH has is with ∠BJA which is due to these angles being vertically opposite

So, ∠FJH and ∠BJA are vertically opposite and hence, congruent. We can say that ∠FJH ≅ ∠BJA
