3(7v-5)-v(10v-9) = 21v - 15 -10v² + 9v = - 10v² + 30v - 15
The answer of this question is<u> 24 toy trains.</u>
<u>Step-by-step explanation:</u>
Given,
Jerry gave away 15 trains .
Jerry left with 9 trains .
Jerry total brought toy trains = given away toy trains + left with toy trains
Total toy trains = 15 + 9
Total toy trains = 24
<u>Jerry brought a total of 24 toy trains.</u>
y = 0.6x - 3.2
The general form of the desired equation is
y = mx + b
where
m = slope of the line
b = y intercept of the line
If two lines are parallel, their slopes will be the same, Since the slope of the
given line "y = 0.6x +3" is 0.6, that will also be the slope of the desired line.
So our equation becomes:
y = 0.6x + b
Now we can substitute the x and y value of the desired point we want the new line to pass through and find b. So
y = 0.6x + b
-5 = 0.6(-3) + b
-5 = -1.8 + b
-3.2 = b
So the desired equation is now
y = 0.6x - 3.2

Answer:
9 and -6 multiply to -54 and add to 3
Step-by-step explanation:
when listing the factors of 54, we can find a pair that add to 3
1, 2, 3, 6, 9, 18, 27 and 54
9 and -6 is the pair.
hope this helps! :D
have a miraculous day, and brainliest is immensely appreciated!! <3
