1 answer:
Answer:
There are <u>250 students</u> in the 6th grade.
Step-by-step explanation:
[] Let us do "number of students" over the percentage. We will use x as the total number of students in the 6th grade.
-> 35% and 100% can be divided by 100 to become decimals
Set up a proportion:
Cross multiply:
85 = 0.34x
Divide both sides by 0.34:
250 = x
Reflexive property:
x = 250

Answer: 16) y=-0.5x+3 and 17) y=2x-3
Step-by-step explanation:
16: The slope-intercept form of a line is y=mx+b, where m is the slope, and b is the y-value at the y-intercept.
Since y=3 at x=0, the y-intercept is (0,3), and b=3.
Slope= where (
) and (
) are two points on the line. Choose (0,3) and (2,2):
Slope==-0.5
Plug m=-0.5 and b=3 into y=mx+b:
y=-0.5x+3
17: The slope-intercept form of a line is y=mx+b, where m is the slope, and b is the y-value at the y-intercept.
Because y=-3 at x=0, the y-intercept is (0,-3), and b=-3.
Slope= where (
) and (
) are two points on the line. Choose (0,-3) and (1,-1):
Slope==
=2
Plug m=2 and b=-3 into y=mx+b:
y=2x-3
