Answer:

A: x ≤ −4

Step-by-step explanation:

Hi there!

We're given the two inequalities -8x + 3 ≥ 27 and  −13x + 5 ≥ 57

we need to find the set of solutions that make the two inequalities true (the intersection)

First, let's solve the two inequalities, starting with -8x + 3 ≥ 27

-8x + 3 ≥ 27

subtract 3 from both sides

-8x≥24

divide both sides by -8 and remember to FLIP the inequality sign, as we're dividing with a negative

x ≤ -3

now for the other inequality:

−13x + 5 ≥ 57

subtract 5 from both sides

-13x ≥ 52

divide both sides by -13 and remember to FLIP the sign

x ≤ -4

please see below for the graph to find the intersection, as well as the final answer

Hope this helps! :)

Equation for (5,-4) (-3,2)
tatuchka [14]

Answer:

y = -\frac{3}{4}x-\frac{1}{4}

Step-by-step explanation:

The equation for a linear function found from two given points is:  y = mx + b, where m = slope and b = y-intercept.  You can find slope from slope formula:

\frac{(y_{2}-y_{1})}{(x_{2}-x_{1})}

Given points (5, -4) and (-3, 2):

\frac{(2-(-4))}{(-3-5)}=\frac{6}{-8}=-\frac{3}{4}

Using the value m = -\frac{3}{4} and the point (5, -4) for x and y:

y = mx + b

-4 = 5(-3/4) + b

-4 = -15/4 + b

-4 = -3.75 + b

-1/4 = b

y = -\frac{3}{4}x-\frac{1}{4}

The lung capacity of the blue whale is 5100L. Convert this volume into gallons. Express your answer to two significant figures a
Vedmedyk [2.9K]
By definition, we have that the conversion of a US gallon to liters is given by:
 1 liter = 3.78541 gallons
 Therefore, we can apply the following rule of three:
 1 liter ---------------------> 3.78541 gallons
 5100 liters --------------> x
 Clearing x we have:
 x = (5100) * (3.78541)

x = 19305.591
 two significant figures:
 x = 19000

 Answer:
 
The lung capacity of the blue whale is:
 
x = 19000 gallons

4. Which of the following can be used
JulsSmile [24]

The option that can be used to support the idea that the set of polynomials is closed under multiplication is; Option C: (10x^(0.5) - 8)(5x^(0.5) + 4)

<h3>What is the Closure property under multiplication?</h3>

When multiplying polynomials, the variables' exponents are added, according to the rules of exponents. It is pertinent to note that the exponents in polynomials are whole numbers. The whole numbers are closed under addition, which guarantees that the new exponents will be whole numbers. Thus, we can also say that the polynomials are closed under multiplication.

Now, looking at the options, we can say that option C is the only polynomial that is closed under multiplication because its' variables and exponents will not change;

(10x^(0.5) - 8)(5x^(0.5) + 4)

The output will retain the same thing.

How do you solve algebraically 8x^2=18
vodka [1.7K]
That would be
x =  + \frac{ \sqrt[]{3} }{ \sqrt[]{2} }
BTW the plus sign is supposed to have this sign underneath it _
Good luck.
