(1/7) Multiplied By x is 1/7x And (1/7) Multplied By Positive 21 is 3. So It Will Then Change To 1/7x + 3 = -6.
Subtract 3 From Both Sides. Then The Equation Changes To 1/7x = -9
Then Since (1/7) Basically Means To Divide You Would Multiply By 7 On Both Sides And Then x Would Equal -63!(:
Then Can Plug In -63 Where x Is To Check Your Work! Hope I Helped!

-2(3x-1)<8 on a number line
Veronika [31]

Answer:

Checkout the image below the explanation.

Step-by-step explanation:

1. First, let's solve the inequality.

Step 1: Simplify both sides of the inequality.

  • -6x + 2 < 8

Step 2: Subtract 2 from both sides.

  • -6x + 2 - 2 < 8 - 2
  • -6x < 6

Step 3: Divide both sides by -6 and flip the sign.

  • \frac{-6x}{-6}  < \frac{6}{-6}
  • x > -1

2. Now that we solved the inequality and got x > -1, that means that all values of x are more than -1. It can be represented on the number-line as this:

I need help can y'all help please
BartSMP [9]
Your domain is all positive numbers, and your range is all numbers. this is because no matter what you plug in for y, x will only ever get extremely close to 0, but never reach it or go below it, and if you put in large values of y x will get very big.

Frieda is 67 inches tall and weighs 135 pounds. women her age have a mean height of 65 inches with a standard deviation of 2.5 i
blsea [12.9K]
<span>Frieda's weight is 1 Standard Deviation above the meanwhile her height is less than 1 Standard Deviation away from the mean. This means her height is closer to the mean than her weight.
As a result, we would say that her weight is definitely more unusual than her height because her weight is more standard deviations away from the mean.

Therefore,
</span><span>in relative terms, it is correct to say that:</span> Frieda's height is more unusual than her weight.

What are the dimensions of a rectangular box with a volume of 50b 3 + 75b2 - 2b - 3?
Inessa [10]

Answer:

\large\boxed{(2b+3)\times(5b-1)\times(5b+1)}

Step-by-step explanation:

The formula of a volume of a rectangular box:

V=lwh

<em>l</em><em> - lenght</em>

<em>w</em><em> - width</em>

<em>h</em><em> - height</em>

V=50b^3+75b^2-2b-3=25b^2(2b+3)-1(2b+3)\\\\=(2b+3)(25b^2-1)=(2b+3)(5^2b^2-1^2)\\\\=(2b+3)\bigg((5b)^2-1^2\bigg)\qquad\text{use}\ a^2-b^2=(a-b)(a+b)\\\\=(2b+3)(5b-1)(5b+1)

Therefore the dinemsions of thisp prism are:

(2b+3)\times(5b-1)\times(5b+1)
