Answer:
y=-2x-7
Step-by-step explanation:
lines are typically written in y=mx+b form, where m is the slope and b is the y intercept
we are given the line y=1/2x-4
perpendicular lines are negative and reciprocal; if the slopes are multiplied together, the result is -1
so to find the slope of the new line, use this formula:
1/2m=-1
multiply by 2
m=-2
so the slope is -2
here's the equation so far, written in y=mx+b form
y=-2x+b
we need to find b
because the line passes through the point (-4,1), we can use it to solve for b
substiute -4 as x and 1 as y
1=-2(-4)+b
1=8+b
-7=b
so b is -7
therefore the line is:
y=-2x-7

Answer:
5
Step-by-step explanation:
yoy need to find hue multiplying factor, this is done by dividing one of the sides in QRS, by one in ABC. you can divide 10 by 4 to give you 2.5, and then multiply that by 2 to get 5
Answer:
2(x+5)

need to make this longer.....
Take 150 / 100 = 1.5
1.5 x 80 = 120
150 - 120 = 30
20% of 150 students is 30
Answer:
6 x 1 = 6
7 x 2= 14
6/14 is the answer
you can divide by 2/2
it is the same because 2/2 = 1 so the answer is the same but simplified
6/2=3
14/2=7
3/7 is the answer
