Answer:
B
Step-by-step explanation:
For a line to be parallel it must have the same slope
6x-2y=-5
+5 +5
6x-2y+5 = 0
+2y +2y
6x+5 =2y
/2 /2
3x+5/2=y So the slope is 3 and we know it can only be either B or D
Now we need to find which line passes through (7,-2) and we find this by plugging 7 into B and D
B. -2= 21-23 TRUE
D. -2 = 21+ 23 FALSE
So the answer is B
Answer:
D r = 4 − 4 cos(θ)
Step-by-step explanation:
Right on edge
Use the pythagoream theorem to check. a^2+b^2=c^2
a=15 b=36 c= 39
225+1296=1521
The equation is true so it is a right triangle.
Answer:
a) 50,000 + 2x > 70,000
Step-by-step explanation:
Mrs. Lobo has an annual salary of $50000 per year plus 4% commission on her sales.
If she makes $y commission from sales, Mrs Lobo total income per year is:
$50000 + $y.
She makes 4% commission on her sales of share with the average price of a share = $50
Average commission from sales = 4% × $50 = 0.04 × 50 = $2
If she sales x shares in a year, her commission would be $2x for the year. Therefore her total income for that year would be:
50000 + 2x
The amount of shares Mrs Lobbo must sell to make an annual income of at
least $70,000 is given by the inequality:
50,000 + 2x > 70,000
