X=number of boys
y=number of girls.
We can suggest the following system of equations:
x+y=33
x/y=3/8
We solve this system of equations by substitution method.
x/y=3/8 ⇒x=3y/8
(3y/8)+y=33
least common multiple=8
3y+8y=33*8
11y=33*8
y=(33*8)/11
y=3*8
y=24
x+y=33
x+24=33
x=33-24
x=9
number of boys /total number of students=9/33=3/11
There are 9 boys and 24 girls in the class.
Answer: C: 9. since 3/11 of the students are boys.
Answer: y = -5x+5
Step-by-step explanation: Slope intercept form is written as y = mx+b where m is the slope of the function and b is the y-intercept of the function. In this linear function, the line crosses the y-axis at (0,5). This is the y-intercept. We can find the slope with the (y2 - y1) / (x2 - x1) by choosing 2 points on the graph. I chose (0,5) and (1,0). If you use the formula, you will end up with -5 as your slope.
Answer:
see below
Step-by-step explanation:
slope intercept form: y=mx+b
you are given the slope, and can plug the points in to find b.
a) -3=2/3(6)+b --> b=-7
y=2/3x+7
b)10=-8(1/2)+b --> b=14
y=1/2x+13
c)4=-3(2)+b --> b=10
y=-3x+10
So its this answer because the y is equal to the x plus the y-intercept but the y is 0 so; y=5/2x
hello there how are you today
you awnser is A and C they both apply
