Answer:

PS = 7

k = 9

Step-by-step explanation:

RS = PQ                   Given

3x  - 7 = x - 1            Substitute algebraic terms. Subtract x from both sides

3x-x - 7 = x - 1 - x    Combine

2x - 7 = - 1                Add 7 to both sides.

2x - 7+7 = -1+7         Combine

2x = 6                      Divide by 2

2x/2 = 6/2

x = 3

Length of PS = x - 1 + x + 3x - 7

Length of PS = 5x - 8

Length of PS = 5*3 - 8

Length of PS = 7

=========================

f(x) = k - x^2

x = 2

f(x) = 5  is the given point

5 = k - x^2      Substitute for x^2

5 = k - 2^2      Expand

5 = k - 4          Add 4 to both sides.

5+4=k-4+4      Combine

k = 9

what is an equation of the line that passes through the point (5,1) and is parallel to the line x+y=9
Ede4ka [16]
Y=9-x is slope-intercept form of that line, which means it has a slope of -1. Parallel lines have the same slope, so the slope of this new line will also be -1.

To find the line that goes through (5,1), we can use a blank equation y=mx+b. We know that m=-1, so we can use the given point to find b:

y=mx+b
Y=-x+b
1=-5+b
6=b

So the line would be y=-x+6.

before getting to school john has a few errands to run john has to walk 5 blocks to the galley and 9 blocks to the library befor
Serggg [28]

Answer:

  9 blocks

Step-by-step explanation:

The total of what John has already walked and the number more he must walk will be equal to the number he has to walk to get to school.

  12 + more = 5 + 9 + 7

  more = 9 + 5 + 7 - 12 . . . . . subtract 12 from both sides

  more = 9

John must walk 9 blocks more.

_____

We recognize that 5+7 = 12, so that last part of the sum totals zero.
