Answer:
<u><em>u +v = < 7,9 ></em></u>
Step-by-step explanation:
You are given u = <9,4> and v = <-2,5>. You are asked to find u+v. all you need to do is to add them with their respective position. u+v = <9-2, 4+5>, u+v = <7,9>. This is the correct answer.
Answer:
<u>y </u> -<u>8=-2</u>
x -4 3
3y - 24=-2 +8
y= -2/3x +32/3
Step-by-step explanation:
Answer: x ≤3
Step-by-step explanation:
Your answer is correct
<span>Twelve diminished by six times a number</span>
<span> </span>
<span>12 - 6x </span>
Since the area of a triangle is in the form
area=0.5(base)(height)
height=base+7
let base=x
area=0.5(x)(7+x)
30=3.5x+0.5x^2
multiply the equation by 2
60=7x+x^2
subtract 60 from both sides
x^2+7x-60=0
(x-5)(x+12)=0
thus x=5 or x=-12 since we are only considering positive answers
x=-12 is rejected
so base=5 and height=5+7=12
