Y = 2x + 1
y = 2(-1) + 1
y= -2 + 1
y= -1
£17.50 is 50% of what number
Now the same in math:
£17.50 = .50 x n pr £17.50 = .5n
Divide both sides by .5
n= £ 35
Answer:
Step-by-step explanation:
The surface area of a sphere with radius r is given by
S = 4 pi r^2
for a radius of 11 units,
S = 4 pi 11^2 = 484 pi = 1520.5 sq. units
This does not correspond to any of the answers.
Please check question.
Answer:
(x-5)(x+6)=0
Step-by-step explanation:
hehe i doing the smae unit rn.
if a=1 (which it does do ac factoring)
you need two numbers that multiply to -30 and add to 1. those numbers are 5 and -6.
substitute 1x for -5x + 6x.
group the numbers into pairs and find their gcf's
x(x-5) 6(x-5)
since the parenthesis r the same yo only need one. Now you need to put x and 6 in a parenthesis.
FINAL: (x-5)(x+6) hope this helps
