Answer:
y=24
z=100
Step-by-step explanation:
5y-40=80(vertical angles)
add 40 to each side
120-40=80
z=180-80
z=100
Answer:
Two points, one at 4 and one at 6.
Step-by-step explanation:
<u>Equations with absolute value
</u>
The absolute value of a number x denoted as |x| is a number with the same magnitude with a positive sign. When we know the result of an absolute value, we cannot know if the original number is positive or negative.
If |x| = a, a>=0, then x=a or x=-a
The equation to solve is |x – 5| = 1. If we apply the above criteria, then
x-5=1 or x-5=-1
Which gives us two possible solutions for x
x=6
x=4
The correct answer is
Two points, one at 4 and one at 6.
Answer:
Input-previous input then multiply this difference by 3, add the squared difference to the previous output to get the current output
Step-by-step explanation:
The first output is predetermined then the subsequent outputs are obtained by subtracting previous input from previous output then we multiply the difference by 3 and add to the previous output for example
Answer:
Step-by-step explanation:
Because of similar triangles formed we can say
h/12=5.5/2
h=66/2
h=33ft
f(2x-3)=4x+5
Let, 2x-3=g
x=(g+3)/2
So,f(2{g+3}/2 -3)=4(g+3)/2 + 5
f(g)=2g+11
So,f(x)=2x+11
f(-2)=7 ##
