Solve the double inequality:<br><br> −3>7x−8>−0.2

Aleonysh [2.5K]

Answer:

No solution.

Step-by-step explanation:

−3> 7x−8 > −0.2

Split this into 2 inequalities:

7x - 8 < -3 Add 8 to both side:

7x < 5

x < 5/7.

and:

7x - 8 > -2 Add 8 to both sides:

7x > 6

x > 6/7.

But x cannot be both less than 5.7 and > 6.7, so No solution.

The smallest of the three circles with center D has a radius

otez555 [7]

Answer:

464 π in²

Step-by-step explanation:

The smallest circle has a radius of 8 in.

The middle circle has a radius of 8 + 4 = 12 in.

The largest circle has a radius of 12 + 4 = 16 in.

So the sum of the areas is:

π (8 in)² + π (12 in)² + π (16 in)²

= 64π in² + 144π in² + 256π in²

= 464π in²

Can someone please help!

artcher [175]

Hello,

First of all the point-slope equation will have this form : $y=ax+b$

$b = y-intercept = 3\\\\a=\dfrac{\Delta y}{\Delta x}=\dfrac{-3-5}{2}=-4\\\\y=-4x+3$

Answer A.

Because :
$if:y+5=-4(x-2)\\\\y+5=-4x+8\\y=-4x+8-5\\y=-4x+3$

A couple quick algebra 1 questions for 50 points!

kkurt [141]

Answer:

Question 6) Neither (Not an inverse variation)

Question 7) Inverse variation

Question 8) Inverse variation

Step-by-step explanation:

These are the two formulas we need to know prior to solving the question.

Direct variation: c times x

Inverse variation: c times 1/x --> c/x

- Here, c is the constant

6. y = x + 7

This is neither. It is not in the form of a direct, or inverse variation, so it does not belong in any category.

7. 14 = xy

This equation is an inverse variation.

xy = 14

y = 14/x

14 is the constant, and the format is the same as for an inverse variation.

8. x = -8/y

This equation is an inverse variation.

yx = -8

y = -8/x

-8 is the constant, and the format is the same as for an inverse variation.

So we can conclude that questions 7 and 8 is an inverse variations, while question 6 isn't.
