Step-by-step explanation:
285+55+285+55+285+55=1020
or another way
285+55×3= 1020
It’s A
Because the line of the graph is only going on 3, they are all positive 3 and the equation what x = 3.which mean they are all equal.

Answer:
<u>145 people were surveyed</u>
Step-by-step explanation:
1. Let's review the information given to answer the question correctly:
Percentage that indicated they preferred walking to running = 90%
2. If 130 people preferred running to walking, how many people where surveyed?
For answering this question, we will use the Rule of Three simple, this way:
x = Number of people surveyed
90 * x = 130 * 100
90x = 13,000
x = 13,000/90
x = 144.44
But we need a whole number for an accurate answer, so we round the value of x to the next whole number.
<u>145 people were surveyed</u>
Answer:
First, solve for two points as an equation instead of an inequality to find the boundary line for the inequality.
For:
x
=
0
y
=
0
+
5
y
=
5
Or
(
0
,
5
)
For:
x
=
−
2
y
=
−
2
+
5
y
=
3
Or
(
−
2
,
3
)
We can now plot the two points on the coordinate plane and draw a line through the points to mark the boundary of the inequality.
The boundary line will be solid because the inequality operator contains an "or equal to" clause.
graph{(x^2+(y-5)^2-0.125)((x+2)^2+(y-3)^2-0.125)(y-x-5)=0 [-20, 20, -10, 10]}
Now, we can shade the left side of the line.
graph{(y-x-5) >= 0 [-20, 20, -10, 10]}
