Answer:
y-7=1/4(x+5)
Step-by-step explanation:
y-3=-4(x+2)
y=-4x-8+3
y=-4x-5
-----------
y-y1=m(x-x1)
y-7=m(x-(-5))
y-7=m(x+5)
perpendicular means negative reciprocal of the slope,
so the slope will be 1/4
y-7=1/4(x+5)
She asked her friends, which does not represent a random sample.
She tried to show cause and effect without doing an experiment (which includes simple random sample, control group, treatment, etc).
So the answer is she did not use a random sample, and tried to show cause and effect with an observational study.
Answer:
The amount of Apple juice poured in each glass is
quarts .
Step-by-step explanation:
Given as :
The quantity of apple juice in pitcher = 
Let the amount equally poured in the 3 glass =
quart
The remaining amount in the pitcher after pour = 
Now, According to question
The quantity of apple juice in pitcher - The amount equally poured in the 3 glass =The remaining amount in the pitcher after pour
or,
-
= 
or,
-
=
Or,
=
Or,
=
∴ 7 × 3 = 12 × x
or, 21 = 12 × x
So , x = 
Or, x =
Hence The amount of Apple juice poured in each glass is
quarts . Answer
Answer:
there is no solution to this
Step-by-step explanation:
4(3x+3)=3x+12
12x+12=3x+12
-3x on both sides
9x+12=12
-12
9x=?
