Answer:
6
Step-by-step explanation:
expand
x-7= 1/4x-10/4
3/4x=18/4
multiply 4 on both sides to get rid of the denominator
3x=18
x=6
check work by substituting
6-7= 1/4(6-10)
-1= 1/4(-4)
-1=-1
they are equal, so it's correct
Answer:
No, because it does not have a constant rate of change
Step-by-step explanation:
look at the changes of the y values when going from one x value to the next.
x always changes by 1.
but y changes by +7, +5, +6.
the change rate is the ratio y/x.
as we can see, this changes in each interval.
so, the change rate is not constant.
but this is the deciding property of a linear function. as the name says, a linear function is a straight line. it has the same incline (= changes rate) everywhere on the line. otherwise it is not a straight line.
Answer:
First, draw a rectangle and draw 3 lines going vertically. Then, draw the diagonal lines (shown in step 3) write the 4 digit number you are multiplying with the 1 digit number on top of the table (step 2) and multiply, when you are done multiplying, add the numbers vertically. Finally, you have your answer
Step-by-step explanation:
3x+7+5x-4=67
8x+3=67
8x=64
x=8, now sub 8 for x
3(8)+7
24+7=31
Answer:EF=31
