Describe what happens to the graph of y=3x+4 when the slope is changed to 1/3

Answers


The graph is still a straight line, it still cuts the y-axis at the point y=4 ,
and it still slants up from left to right.

But it becomes a lot less steep.  The original line only had to go 4 inches
to the right in order to rise 1 foot.  The new line has to go 3-feet to the right
in order to rise 1 foot.

What is the value of the numerical expression 5/8-5/12(3-1/4)+2/3

Answers

Make bottom numbers same
find least common multipules of 8,12,4 and 3
8=2 times  2 times 2
12=2 times 2 times 3
4=2 times 2
3=3
lcm=2 times 2 times 2 times 3=24

5/8 times 3/3=15/24
5/12 times 2/2=10/24
3/1 times 24/24=72/24
1/4 times 6/6=6/24
2/3 times 8/8=16/24
we now have
15/24-10/24(72/24-6/24)+16/24
pemdas
simplify parenthasees first
72/24-6/24=66/24

now we have
15/24-10/24(66/24)+16/24
multiply
15/24-660/576+16/24
make same bottom number
15/24 times 24/24=360/576
16/24 times 24/24=384/576
360/576-660/576+384/576
84/576
7/48

answer is 7/48
