Answer:
1st one)
y = 4
2nd one)
y = -12.5
Step-by-step explanation:
5y - 20 = 0
add 20 on both sides:
⇒ 5y - 20 + 20 = 0 + 20
⇒ 5y = 20
divide 5 on both sides
⇒ [tex]\frac{5y}{y} = \frac{20}{5}[/tex]
⇒ y = 4
2y + 25 = 0
subtract 25 on both sides
⇒ 2y + 25 - 25 = 0 - 25
⇒ 2y = -25
divide 2 on both sides:
⇒ [tex]\frac{2y}{2} = \frac{-25}{2}[/tex]
⇒ y = -12.5
Use the distributive property to remove the parentheses.

the domain of y=x^2 is
The range of y=x^2 is
Answer:
Domain is all real Numbers
Range is all numbers over 0 - (0,
∞
)
Explanation:
One thing that you have to remember is that when you are finding the domain of a polynomial, it is all real number. it runs from
(
−
∞
,
∞
)
For finding the range, in a quadratic formula, you have to find when the finction has it's vertex. That is the place that the max or min happens and then you can find the range from there.
in this situaltion we found that the vertex is at the the origin at (0,0)
therefore the range is (0,
∞
)
Answer:
the domain of y=x^2 is: all real numbers
the range of y=x^2 is: y >= 0

Answer:
86%
Step-by-step explanation:
28 were placed on suspension
200 are total (including that 28)
not placed on suspension are the rest, so 200-28=172
172 out of 200 = 86% not placed on suspension
Answer:
86% Pls consider marking brainliest if correct.
Step-by-step explanation:
Okie lets see
In all : 200
Removed : 28
To find percentage : 200-28/200
200 - 28 = 172
172/200 = (172/2)/(200/2)
I did this because 200 is 100x2, and because percentage is over 100
172/2 = 86
200/2 = 100
86/100 = 0.86 = 86%

Step-by-step explanation:
1st , notice that our problem is about an eight part whole. I mean, the questions are around an object of 8 parts. so start thinking 1/8 ths
A) asks about P(7) ... they want to know.. how often the spinner will land on 7. so if it's totally random, 7 will happen just as likely as any of the other numbers so 7 will happen 1/8 th of the time
as a fraction it's 1/8 as a decimal it's 0.125 and as a percent it's 12.5 %
B) asks about P(2 or 6 ) [ btw, p here stands for probability ]
so it's 1/8 + 1/8 = 1/4 or one quarter of the time we would get a 2 or a 6
as a fraction it's 1/4 , as a decimal it's 0.25 and as a percent it's 25%
C) asks about P( greater than 4) or P( >4) so that's the whole left side of the circle :0
as a fraction it's 1/2 as a decimal it's 0.5 and as a percent it's 50%
D) P( not a 5) or P( ~=5) so every thing but a 5
as a fraction that's 7/8 as a decimal it's 0.875 and as a percent that 87.5 %

Joseph took a taxi from his house to the airport. The taxi company charged a pick-up
fee of $3.10 plus $2 per mile. The total fare was $21.10, not including the tip. Write
and solve an equation which can be used to determine m, the number of miles in the
taxi ride.
Answer:
2m + 3.10 = 21.10
m = 9
Step-by-step explanation:
First Step
2m + 3.10 =21.10
Subtract 3.10 from both sides
Second Step
2m = 18
Divide 2 from both sides
m = 9
The equation is 2m + 3.10 = 21.10
And, the number of miles in the taxi ride is m = 9.
