Answer:
c y=6x+4
Step-by-step explanation:
y=mx+b. m= slope b= y intercept
at x=0, the graph is at y=4, so that is b. Slope is up/over. so from point (0,4) to point (2,16), the graph went up 12 and over 2. 12/2=6
Answer: A)1/2
Step-by-step explanation: m = y2-y1/x2-x1
I will use the values (1,2) and (3,3) from the table
1=x1, 2=y1, 3=x2, 3=y2
m = 3-2/3-1
m=1/2
first off, I'd like to point out that for the 5th test, he has 96, and that's +6 above 90, and therefore it should be 6.
if all the above/below numbers, summed up yield 0, that simply means the average is an even 90 on average for all 6 tests, if they yield above 0, is above on the average, and if it's below 0, a negative value, he needs to do more work.
-7+4-11+7+6-3 = -4.
you can think of it this way, if he had 90 on all 6 tests, the above/below row will show 0, 0, 0, 0, 0, 0. If any of the tests was above 90, that row will yield a sum more than 0, and if any of the tests were below, that sum will be a negative value.
Answer:
-4x + 12 = 20 is incorrect. she added 12 to 20 instead of subtracting 12 from both sides.
Step-by-step explanation:
It should have been, write problem
-4(x - 3) = 20
Use distributive property.
-4x + 12 = 20
subtract 12 from each side
-4x =8
divide each side by -4
x = -2
Answer:
2.20$
11$
Step-by-step explanation:
18.70/8.5=2.2
2.2= 2.20$
2.2x5=11
11=11$
