Hey there, below you will find the work and answer to your question.
2x-5=4
First lets get the 2x by itself so we have to add 5 on both sides.
2x-5=4
+5 +5
2x=9
Now we need to get the X by itself so divide each side by 2

Now we are left with the following
X=

We must simplfy the fraction
2 will go into 9 four times with 1 left over. So the mixed fraction answer would be:
x=

As a decimal you would just divide 9 and 2
x=4.5
Hope this helped!
Answer:
x= -7
Y= -3
Step-by-step explanation:
Answer:
f(1) - 1 = -3
Step-by-step explanation:
Step 1: Find f(1)
f(1) = -3(1) + 1
f(1) = -3 + 1
f(1) = -2
Step 2: Find f(1) - 1
f(1) - 1 = -2 - 1
f(1) - 1 = -3
Answer:
150 degrees
Step-by-step explanation:
90+30=120.
Since angle afc is bisected by line bf, that means that the angles formed equal each other. Since the total angle measurement is 180 degrees, we do 180-120=60. 60/2=30. 120+30=150 degrees.
