−7x−50≤−1 AND−6x+70>−2

Mathematics
1 answer:
fgiga [73]4 years ago

Answer:

-7\geq x and [-7,12) in interval notation.

Step-by-step explanation:

We have been given a compound inequality -7x-50\leq -1\text{ and }-6x+70>-2. We are supposed to find the solution of our given inequality.

First of all, we will solve both inequalities separately, then we will combine both solution merging overlapping intervals.

-7x-50\leq -1

-7x-50+50\leq -1+50

-7x\leq 49

Dividing by negative number, flip the inequality sign:

\frac{-7x}{-7}\geq \frac{49}{-7}

x\geq -7

-6x+70>-2

-6x+70-70>-2-70

-6x>-72

Dividing by negative number, flip the inequality sign:

\frac{-6x}{-6}

x

Upon merging both intervals, we will get:

-7\geq x

Therefore, the solution for our given inequality would be -7\geq x and [-7,12) in interval notation.

Answer:

x=8

Step-by-step explanation:

The angles shown are vertical angles and vertical angles are equal

13x+19 = 16x -5

Subtract 13x from each side

13x-13x+19 = 16x-13x -5

19 = 3x-5

Add 5 to each side

19+5 = 3x-5+5

24 = 3x

Divide by 3

24/3 = 3x/3

8 = x

Can someone help with this asap
zmey [24]

Answer:

1. 60

2. true

3.false

Step-by-step explanation:

1. All the angles in an equilateral/equiangular triangles have the same side length and the same angle, since all the angles in a triangle add up to 180 degrees, 180 divided by 3 is 60

2 and 3. An isosceles is a triangle with two equal sides. The angles opposite the equal sides are also equal.  An equilateral triangle has sides of the same length.

P(x)= x^3+4x^2-8x-6 <br><br> a= -2
melisa1 [442]
Unfortunately, you haven't shared the instructions for this problem.  My guess is that you are to evaluate <span>P(x)= x^3+4x^2-8x-6 for x = a = -2.

If that's the case, then

P(-2) = (-2)^3 + 4(-2)^2 - 8(-2) - 6.  This simplifies to:

         =  -8      +  16 + 16 - 6  = 18 (answer)</span>

What is the following product?<br> (21/7+316)(5./2+4-13)
Anuta_ua [19.1K]

Answer:

-2073.5

Step-by-step explanation:

We will have to solve this question using step by step procedure

So let's solve

(21/7+316)(5/2+4-13)

(21/7+316)

Lcm is 7

21+2212/7

2233/7

(5/2+4-13)

Lcm is 2.

5+8-26/2

13-26/2

-13/2

Back to the question

(2233/7)(-13/2)

-29029/14

-2073.5

Claudia works as a manufacturer of decorative jewelry boxes. A customer would like her to create some boxes with the following c
KiRa [710]

Answer:

Step-by-step explanation:

Presuming  represents the length of the box (which you should have specified), your volume function:

is correct.

V(x)=-x^3+33x^2-90x=0

Obviously, in order to have a box, all three dimensions must be positive numbers.

 

Since the height is 3 less than the length, the length must be greater than 3 so that the height will be greater than zero. Since the sum of length and width is 30, the length must be less than 30. Hence, the possible range of values for  is  

If you know enough calculus to be able to take the derivative of this function, set the first derivative equal to zero and solve. You will obtain two possible extrema. Only one of these extrema will lie in the the acceptable range of values,  

If you don't know the Calculus, then the best you can do is to graph the function and eyeball it.
