The discriminant is the value that is b^2 - 4ac.
When this number is <0 there will be 2 complex solutions. Letter D.
You would be taking the sqrt of a negative number resulting in a
" +- i sqrt of a number"
5 pounds- $17.50
1 pound- $17.50 divide by 5 pounds then multiple 1 pound=$3.50
10 pounds- $35
15 pounds- $52.50
20 pounds-$70
25 pounds- $87.50
30 pounds-$105
Answer:
False
Step-by-step explanation:
y=x-2 y=3x+4
Substitute the point into both equations and see if it is true
2=4-2
2=2 true
and
2=3*4+4
2 = 12+4
2 =16
False
It is not a solution
24.12 because you have to divide 34 into 820 and then you get 24.12
Answer:
1) 8x- 4+3y
2) 12x- 28
3) 6 (3x+2)
4) 7x+2
Step-by-step explanation:
1) 5x +3 +4y-7+6x-y-3x
8x+3+4y-7-y
2) 4x3x-4x7
12x-4 x 7
3) 18x+12
6(3x+2)
4) 9x+ 1-7x +4+5x- 3
7x+1+4-3
Im sorry I wanted to answer it as quick as possible sorry if you dont understand.
