$-c+b-a=?\\\\substitute\ values:\\
a=-2,\ b=-4,1\ c=5\\\\
-c+b-a=-5+(-4,1)-(-2)=-5-4,1+2=-9,1+2=\\\boxed{-7,1}$

For this question, you can substitute in all the values for the variables.
-c + b - a
= -(5) + (-4.1) - (-2)
= -5 - 4.1 + 2
= -9.1 + 2
= -7.1

Hope this helps! :)

What is the y cordinate of the solution solve 8 and 9

Flauer [41]

Answer:

8) The y coordinate of the solution: 4

9) Average of change from x = 2 to x = 4: 11

Step-by-step explanation:

y = 2x + 2

y = x^2 + 3

x^2 + 3 = 2x + 2

x^2 - 2x + 3 - 2 = 0

x^2 - 2x + 1 = 0

(x - 1)^2 = 0

x - 1 = 0

x = 1

Plug in x = 1 into either those 2 equations to find y

y = 2(1) + 2 = 4

y = (1)^2 + 3 = 1 + 3 = 4

Answer:

The y coordinate of the solution is 4

p(x) = x^2 + 5x - 2

p(2) = 2^2 + 5(2) - 2 = 4 + 10 - 2 = 12

p(4) = 4^2 + 5(4) - 2 = 16 + 20 - 2 = 34

Average of change from x = 2 to x = 4:

[p(4) - p(2)]/[(x(4) - x(2)] = (34 - 12)/(4-2) = 22 /2 = 11

Answer:

Average of change from x = 2 to x = 4 :11

Drag and drop each pair of lines into the correct category to indicate whether the pair of lines are parallel, perpendicular, or

ANTONII [103]

Answer:

Step-by-step explanation:

(1). $\frac{1}{7}$ x + y = 9 and y = - 7x ( Neither ) ; lines intersect.

(2). y = 3x - 3; 12x - 4y = 12 ( Neither ) ; Lines are overlapped or both equation are of the same line.

(3). 7y = 2x + 1; 14x + 4y = 12 ( Perpendicular ) ; $m_{1}$ = $\frac{2}{7}$ and $m_{2}$ = - $\frac{7}{2}$ , slopes are opposite reciprocals.

(4). x - 4y = 18; y = x + 4 ( Neither ) ; lines intersect.

(5). 3x - 4y = - 1; 3y = - 4x + 5 ( Perpendicular ) ; $m_{1}$ = $\frac{3}{4}$ and $m_{2}$ = - $\frac{4}{3}$ , slopes are opposite reciprocals.
