Find the equation of the line that passes through the points (12,21) and (46,33). V.35r-162
AnnZ [28]

Answer:

the answer is Y=(6/17)X + (285/17)

Step-by-step explanation:

1. Identify the X and Y coordinate of each point.            

for example, the first point could be (12,21), therefore X1 = 12 and Y1 = 21 and the second point is then (46,33), therefore X2 = 46 and Y2 = 33

2. to find the equation of the line it is necessary to find the slope.

knowing that the equiation of the slope is M = Y2-Y1/X2-X1 we replace

  m=\frac{33-21}{46-12}=\frac{12}{34} and then we simplify the result to \frac{12}{34}

3. Using the Point-slope equation which is  Y-Y1=M(X-X1) we replace

 Y-33=\frac{6}{17}(X-46)

Y=\frac{6}{17}X-\frac{276}{17}+33

Y=\frac{6}{17}X+\frac{285}{17}

PLZ HELP ME!!
marissa [1.9K]

Answer:

200 trucks

Step-by-step explanation:

There's about 15 trucks in the 2nd row from the right. It looks to be about 1/2 the size of the rows to the left of it.

So based on that, I can assume, there are about 30 trucks in each of the 5 long rows, and both of the short rows would make up about another 30 trucks total. There are various trucks parked along the perimeter or between rows, so I estimated there would be about 20 of those based on 3 per row.

30 x 5 = 150 +30 = 180 + 20 = 200

Pete borrowed $400 for 1 year. He paid back a total of $440. What was the interest rate per year?
OleMash [197]

I=PRT/100

1. Make R (rate) subject

R/100= I/PT

2. Substitute and calculate

r/100= i/pt

r/100= 40/400 × 1

(<em>4</em><em>0</em><em> </em><em>i</em><em>s</em><em> </em>from 440-400.<em>T</em><em>h</em><em>e</em><em> </em><em>i</em><em>n</em><em>t</em><em>e</em><em>r</em><em>e</em><em>s</em><em>t</em>)

r/100= 0.1

r/100×100= 0.1×100

r=10% (interest rate per year)

To confirm

I=PRT

I= 400×10/100×1

I= $40 (Interest)
