Answer: -1 three times and -1 five times

Step-by-step explanation:

-1 three times = -1 X -1 X -1 = -1

-1 two times = -1 X -1 = 1

-1 four times = -1 x -1 x -1 x -1 = 1

-1 five time = -1 x -1 x -1 x -1 x -1 = -1

Therefore -1 three times and -1 five times will be negative

Answer:

(-1)three times and (-1five times)

Step-by-step explanation:

-1 three times

-1×-1×-1=-1

-1 two times

-1×-1=1

-1 four times -1×-1×-1×-1=1

-1 five times

-1×-1×-1×-1×-1=1

the easiest way is that when it is multiplied by and even number it will be positive but if it is an odd number it will be negative

Answer:

Is y = 4x - 7 a linear function?
Is y = 6x² - 1 a linear function?
Is y = $\frac{1}{2x}$ + 10 a linear function?

Step-by-step explanation:

Yes it is - when you graph this equation, it results in a [straight] line, signalling that it is a linear function.
No it's not - when you graph this equation, it results in a v- kinda shape on the graph. Linear functions are [straight] lines on a graph, and this line wasn't straight. In fact, this wasn't even a line.
No it's not - when you graph this equation, it results in a bend at the origin. The line on the graph is not straight, so this is not a linear equation.

For the graphs -

The first one represents the linear function [y = 4x - 7]

The second one (that looks like an L) represents the last not linear function [y = $\frac{1}{2x}$ + 10]

The third one (that looks like a V) represents the first not linear function [y = 6x² - 1]

Solutions to -8x + 5 less than or equal to 11

Vilka [71]

Answer:

$x\geq -\frac{3}{4}$

Step-by-step explanation:

$-8x+5\leq 11\\\\1. -8x\leq 11-5\\ -8x\leq 6$

Isolate the parts of the equation with the x variable

$2. \frac{-8}{-8} x\geq\frac{6}{-8} \\x\geq -\frac{3}{4}$

When you divide or multiply by a negative number in inequalities, you must flip the sign of the inequality.

Help!!!! And is the first on correct

ExtremeBDS [4]

2s+5<span>≥49

First: Subtract 5 on both sides
You'll get: 2s </span><span>≥ 44
Last: Divide each side by 2 so your s would be alone
You'll get: s </span><span>≥ 22 <That would be your answer

HOPE THIS HELPS! ^_^</span>

Please help explanation if possible

egoroff_w [7]

Answer: x = 2 and y = -4

x + 2y = -6

x = -6-2y

Putting this in value of x in

6x + 2y = 4

6(-6-2y) + 2y = 4

-36-12y+2y = 4

-10y = 4+36

y = 40/(-10)

y = -4

Now putting this value of y in

x + 2y = -6

x + 2(-4) = -6

x -8 = -6

x = -6+8

x = 2

Therefore x = 2 and y = -4

If we put these values we can check this

x + 2y = -6

2 + 2(-4) = -6

2 -8 = -6

-6 = -6
