Convert the denominator of the first two fractions to 24 since 3 and 8 can fit into 24.
3/8=9/24
2/3=16/24
Now add them together.
9/24+16/24=25/24
Next add the second two fractions 9/24 and 16/24.
9/24+16/24=25/24
Since all fractions equal 25/24, the equation was true!
Hope this helps!
Find f(-2) f(x)=9x^2-5x+2
f(-2) means replace x in the equation with -2:
f(-2)=9(-2)^2-5(-2)+2
= 9(4) +10 + 2
= 36 +10 + 2
= 48
f(-2) = 48
Answer:
Suppose that we have two line segments, AB and CD. We know that they have the same length.
I know that AB¯¯¯¯¯¯¯¯=CD¯¯¯¯¯¯¯¯ means AB is identical to CD (aka. They are the same lines), and also that AB¯¯¯¯¯¯¯¯≅CD¯¯¯¯¯¯¯¯ means that AB and CD have the same size, but what does AB=CD mean?
Step-by-step explanation:
Answer:
In this equation x = 2
Step-by-step explanation:
First, it is easiest to convert these words to numbers. That would make it
4 - <em>x </em>· 7 = -10
First subtract 4 from both sides.
4 - <em>x</em> · 7 - 4 = - 10 - 4
Then you simplify.
-<em>x ·</em> 7 = -14
Divide both sides by 7.
Then you simplify that fraction to 2 and thats how you get your answer.
