One term for math is mathematics.
Answer:
Step-by-step explanation:
(-8,1) is ⊥ to y=2x-17
from y=mx+c
comparing with
y=2x-17
m₁₌2
for perpendicularity m₂=-1/m₁
m₂₌-1/2
equation of a line with one point y-y₁/x-x₁=m
(-8,1) are x₁ and y₁ respectively
y-1/x-(-8)=-1/2
y-1/x+8=-1/2
cross multiply
2(y-1)=-1(x+8)
2y-2=-x-8
2y=-x-8+2
2y=-x-6
divide both side by 2
y=-1/2x-3
Letter of application is intended to land in your desired job or institute. Letter of application is a letter written to the institutions that a person wanted to be in. This will be tend the basis of the impression of the receiver, or the interviewers.
They sold 1620 units in total during the busiest month. Due to this, the highest month for coat sales is 450% of the lowest month. They sell 360 units in the month with the lowest sales.
<h3>What is equation?</h3>
When two expressions are connected with the equals sign (=) in a mathematical formula, it expresses the equality of the two expressions.
Let x represent the largest number of jackets sold during the busiest month.
So, x= 450% of 360
⇒x=4.5 × 360
⇒x=1,620
So, 1620 units total were sold by them during the busiest month.

We can usually get a couple of facts for these that let us rule out answers without working out all the details.
The green and red areas are below a CUP parabola, opening up. CUP stands for concave up positive, and tells us there's a positive coefficient on x². Unfortunately all the choices have a positive 1 coefficient, no help here.
Since the areas are below they're going to be y ≤ x² + other stuff. That rules out B and C.
The red and blue parts are below the line, and the line has a positive slope. So that's y ≤ mx + b where m>0 is the positive slope. That rules out D with the negative slope.
Answer: A
