Answer:

x = 3/7y - 13/7

Step-by-step explanation:

7x-3y=-13

  +3y   +3y        Add 3y to both sides

7x = 3y - 13       Divide both sides by 7

x = 3/7y - 13/7

We need to compute the slope of the graph shown

m = (y2 - y1)/(x2 - x1)
m = (25-10)/(5-2)
m = 15/3
m = 5

The slope of 5 means the graph tells us "she is walking 5 feet per second".

So the first part of her walk is at 4 feet per second, then the second part of her walk is at 5 feet per second. The second part of her walk is faster. As a story scenario, perhaps she realizes she is going to be late getting home which is why she is walking a bit faster now.

One cylinder has a volume that is 8 Centimeters cubed less than StartFraction 7 over 8 EndFraction of the volume of a second cyl
vlada-n [284]

Answer:

  • D. StartFraction 7 over 8 EndFraction x minus 8 = 216; x = 256 centimeters cubed

Step-by-step explanation:

<u>Equation for the volume and solution:</u>

  • 7/8x - 8 = 216
  • 7/8x = 216 + 8
  • 7/8x = 224
  • x = 224*8/7
  • x = 256 cm³

Correct option is D.

What is the range of the function g(x)=[x]+1
Lerok [7]

<em>Assuming [x] means the closest integer to x</em>

Answer:

(-\infty, \infty)

Step-by-step explanation:

We can see that for any integer x, there will always be a [x], so there will always be a [x]+1. So, we don't need to worry about the domain impacting the range.

[x] can be any integer from -\infty to \infty, and as \infty+1=\infty(at least in terms of a function's range and domain), the range of [x]+1 is equal to the range of [x], which is (-\infty, \infty).

So, the answer is \boxed{(-\infty, \infty)} and we're done!

Which of the following statements is false? -(-5) = 5 |-5| = -5 -|-5| = -5 -|5| = -5
TiliK225 [7]

Your question has been heard loud and clear.

Well -(-5)=5

5/-5/= -5

/-5/5= -5

So basically , the statement is false because   -5(-5) not equal to -5/-5/

Thank you
