Answer:

y= -(1/3)x -r

Step-by-step explanation:

a perpendicular line has the slope of the line that it's perpendicular but its the negative reciprocal of it. So for ex: line 1 = 2x then the line perpendicular to it is -1/2x.

In this case, the slope is 3x. The line perpendicular to it therefore, should be -1/3x.

The problem states the line has the same y-intercept so it has to still be -r.

So the equation of the line perpendicular to y=3x-r with the same y-intercept is y=-(1/3)x -r

It cost $36.75 for three tickets to visit the science center. It cost $51 for 4 tickets to visit the zoo. Which attraction will
Ber [7]
Find the cost for one ticket for the science center.
36.75 ÷ 3 = 12.25
Multiply the product with 12 to get the cost of 12 tickets.
12.25 × 12 = 147
Find the cost of 1 zoo ticket.
51 ÷ 4 = 12.75
Find the cost of 12 tickets by multiplying the product and 12
12.75 × 12 = $153
12 Science Center Tickets cost $147
12 zoo tickets cost $153

The Zoo costs more than the Science Center.

To find out how much more the Zoo costed, subtract 147 from 153.
153 - 147 = 6
The zoo only costs $6 more for 12 students.
So, you're answers are Zoo and $6

Suppose a charity received a donation of 12.7 million. If this represents 29% of the charity's donated funds, what is the total
DanielleElmas [232]

The total amount of its donated funds is  43\frac{23}{29}.

Given,

In the question:

A charity received a donation of 12.7 million.

If this represents 29% of the charity's donated funds.

To find the total amount of its donated funds.

Now, According to the question:

Based on the given conditions:

Received donation is = 12.7 million

Charity Funds = 29%

Formulate;

12.7 ÷ 29%

12.7/29%

= 12.7/0.29

Multiply both the numerator and denominator with the same integer

= 1270/29

= 43\frac{23}{29}

Hence,  The total amount of its donated funds is  43\frac{23}{29}.

A system of linear equations is graphed. Which ordered pair is the best estimate for the solution to the system? (12, 0) (1, 1)
GuDViN [60]
Line 1--------- >(0,2)     (1,-1)
y=mx+b         m=(-1-2)/(1-0)=-3
2=(-3)*(0)+b----- > b=2
y1=-3x+2

Line 2--------- >(0,-1)     (2,2)
y=mx+b         m=(2+1)/(2-0)=3/2
-1=(3/2)*(0)+b----- > b=-1
y2=(3/2)x-1

<span>using a graphic tool
see attached figure</span>

the best estimate solution for the system is <span>(1, 1) 
because </span>is the only one within the range of the x axis (-5,5) and the y axis (-5,5)
