Answer:
a=2
Step-by-step explanation:
First, we need to add 1/2 over, but we need a common denominator
To get a common denominator of 4, multiply 1/2 by 2/2
1/2*2/2=2/4
5/8a-1/2=3/4
5/8a-2/4=3/4
5/8a=5/4
Then, multiply by the reciprocal of 5/8 to isolate a
8/5(5/8a)=5/4(8/5)
a=40/20
a=2
Hope this helps!
Answer: x = 12
Step-by-step explanation:
We know that the whole angle is 90°. Therefore, we can set up our equation like this:
90 = 50 + 3x + 4
Lets combine like terms:
90 = 54 + 3x
Now, let’s isolate the variable. To do this, we have to move 54 to the other side, making it negative.
90 - 54 = 3x
36 = 3x
Now, you divide, the leave the variable by itself.
=
Therefore, x = 12.
Answer:
Axis of symmetry is
C) x = 1
Step-by-step explanation:
we are given equation as
we can use axis of symmetry formula
Let's assume we are given quadratic equation as
Axis of symmetry is
now, we can compare both equations
and we get
now, we can find axis of symmetry
your need to factor this quadratic
2(x^2 +3x+2)=0
2(x+1) (x+2)=0
the intercepts are -1, -2
Perimeter= 2(4x -17) + 3x + 9
simplify
8x - 34 + 3x + 9
rearrange commons
8x + 3x -34 + 9
simplify
11x - 25
the perimeter should equal 11x -25!
