Answer:
Using the graph, just look at the exact spot where the lines are intersecting and that point is the solution.
The solution is: (1.2, -1.6)
Step-by-step explanation:
You can also test this by plugging the values of the point into both equations.
Answer:
-16
Step-by-step explanation:
-5-(3^2+2)
Parentheses first
-5-(9+2)
-5-(11)
Subtract
-16
Answer:
1. 4(.8)-3.5= 3.2-3.5= -0.3
2. 3(3)--5(5)-9(-1)= 9 - 25 + 9 = 18 - 25= -7
Simplify √-y to √yi
3+ 2y = √yi
Square bot sides
(3 + 2y)^2 = -y
Expand
9 + 12y + 4y^2 = -y
Move all terms to one side
9 + 12y + 4y^2 + y = 0
Simplify 9 + 12y + 4y^2 + y to 9 + 13y + 4y^2
9 + 13y + 4y^2 = 0
Split the second term in 9 + 13y + 4y^2 into two terms
4y^2 + 9y + 4y + 9 = 0
Factor out common terms in the first two terms, then in the last two terms
y(4y + 9) + (4y + 9) = 0
Factor out the common term 4y + 9
(4y + 9)(y + 1) = 0
Solve for y
y = -9/4, -1
Check solution
when y = -9/4, the original equation; 3 + 2y = √-y does not hold true. We will drop y = -9/4 from the solution set.
Therefore,
<u>y = -1</u>
A mixed <u>fraction</u> is an improper fraction turned into a whole number and a proper fraction
proper fraction: top number is SMALLER than the bottom number (fraction means part of) exg 1/3
improper fraction: top number is GREATER than the bottom number (more than 1) exg. 4/3
mixed: an improper fraction written as a whole number and a proper fraction exg
4/3=imporper mixed=1 and 1/3
so
575%
percent means parts out of 100
575%=575/100=57.5/10=5.75/1=5.75/1=5.75=5 and .75/1
we know that 0.75=3/4
so
5 and 3/4 is the answer
