Answer:
Step-by-step explanation:
stupid enough
y=mx+b
slope = 16-12/3-6
-4/3
plug in x and y
16=-4/3(3)+b
b=20
<h2><em><u>Red</u></em></h2>
Y=mx+b or -2=-1 x 2+b, b= -2(-1)(2) b=0
Therefore the equation of the line is
y=-1x
Answer:
A and B are correct
Step-by-step explanation:
if x:y is 1:3 then x is 1 and y is 3
1/3 of 3 is 1 so A is correct
3/4(1+3) is 3 so B is correct
But
1/4 × 3 is not 1 so C is not correct
3/4 ×1 is not 3 so D isn't correct
Answer:
y should equal -25 if i did the math right
Step-by-step explanation:
-12 and 9 have a difference of -21 so if i subtract -21 from -4 it would equal -25.. hope this helps!!
Answer:
40% of the class is Girls, so 12 students are girls
Step-by-step explanation:
add up the ratio
2+3=5
divide by 5
30/5=6
multipy ratio to find totial number of students
2*6=12
2*3=18
divide the number of students to get the pecentage
12/30=0.4=40%
18/30=0.6=60%
