Step-by-step explanation:
4/5 ÷ 15
= 4 / 5 × 1/15
=4/75
Answer:
-62.8 is the answer .......................
Ah, looks like a special right triangle to me, just got done learning about these.
Alright, so, since this is a 30-60-90 triangle, 6 is the smallest leg (as across from 30 degree is the smallest leg), labeled as s. Across from the 90 is 12, as that is 2s.
The missing side, across from the sixty, would be 6 square root of 3 (fourth answer).
Solutions are x intercepts
factor
what 2 numbers multiply to 1 and add to -2? -1 and -1
(x-1)(x-1)=0
set to zero
x-1=0
x=1
vertex
get into y=a(x-h)^2+k form
how nice, it is actually
y=1(x-1)^2+0
the vertex is (1,0)
and since 1 is positive, it opens up and the vertex is a minimum
range is the y values
the min value is y=0
max is inifnity
range is from 0 to infinity
domain is the numbers you can use
use can use all real numbers
<span>Let the variable A represent the number that goes in the blank.
-7y + 5(3 + Ay) = 3y + 15
-7y + 15 + 5Ay = 3y + 15
-7y + 5Ay = 3y
(-7 + 5A)y = 3y
-7 + 5A = 3
5A = 10
A = 2
Answer: D. 2
