because most of 70% of the water is sea salt and clean water comes from frozen underground.
Consider the following expression and determine which statement are true.
Answer:
A and B
Step-by-step explanation:
A is correct because the three terms are x², 5yz, and -8.
B is 100% correct I guarantee it.
C is incorrect because ² is not a coefficient.
D is incorrect because there are three factors in that multiplication term: 5, y, and z.
A box contains 315 half inch conduit couplings and weighs 119 pounds . An identical box also contains half-inch conduit couplings and weighs 47 pounds . How many coupling are in the second box ?
Answer: See explanation
Step-by-step explanation:
Let the coupling that are in the second box be represented by x.
We are informed that a box contains 315 half inch conduit couplings and weighs 119 pounds and that an identical box also contains half-inch conduit couplings and weighs 47 pounds. This can be represented in an equation as:
315/119 = x/47
Cross multiply
119 × x = 315 × 47
x = (315 × 47) / 119
x = 14805/119
x = 124.4
There are about 124 couplings in the box.

Answer:
(-3, -8)
Step-by-step explanation:
The point is in the third quadrant, so both coordinates must be negative. -3 represents the x coordinate and -8 represents the y coordinate.
Determine the maximum or minimum value of the following quadratic function. LaTeX: f\left(x\right)=-3\left(x+5\right)^2-1f ( x ) = − 3 ( x + 5 ) 2 − 1
Answer:
Step-by-step explanation:
[tex]y=-3(x^2+10x+25)-1\\ \\ y=-3x^2-30x-76\\ \\ dy=-6x-30\\ \\ d^2y=-6\\ \\ \text{Since the second derivative is always negative, when the first derivative is equal to zero the function will be at a global maximum.}\\ \\ dy=0=-6x-30\\ \\ x=-5\\ \\ f(-5)=-1\\ \\ \text{So the global maximum occurs at the point (-5,-1)[/tex]

please help me with this angle question :)
Answer:
its an acute angle
Step-by-step explanation:
its an acute angle be cause its small than a right angle
Answer:
angle AED = 70 degrees
angle x = 10 degrees
Step-by-step explanation:
since angle ABD = 110 degrees, major arc AED = 2(110) = 220 degrees
since angle ADB = 40 degrees, minor arc AB = 2(40) = 80 degrees
minor arc BD = 360 - 220 - 80 = 60 degrees
arc AB + arc BD = arc ABD
arc ABD = 80 + 60 = 140 degrees
angle AED = 1/2 (140) = 70 degrees
angle EAD = angle AED because isosceles
arc ED = 2(70) = 140 degrees
arc AE = arc AED - arc ED = 80 degrees
angle x = 1/2(arc AE - arc BD) = 1/2(80 -60) = 10 degrees
what is this plx help???/?
Answer:
B) 9 square units
Step-by-step explanation:
Split the shape into a right triangle and a rectangle.
The rectangle is 2 by 3, so multiply 2 x 3 for the area: 6.
The triangle has a height of 3 and a base of 2. Multiply to get 6. Then divide by 2 to get: 3.
Add 6 + 3 to get 9 square units.
Hope it helps!

Step-by-step explanation:
How do I complete the square for 4x^2+ 8x-5= 0?
Answer:
man I have no idea dude I don't really know squares if you're talking about square root I really don't know
Answer:
x = [tex]\frac{1}{2}[/tex], - [tex]\frac{5}{2}[/tex]
Step-by-step explanation:
This is not so fun!
[tex]4x^{2} + 8x - 5 = 0\\[/tex]
Step 1: Move the 5 to the right side
[tex]4x^{2} +8x = 5[/tex]
Step 2: Divide thru by 4
[tex]x^{2} + 2x = \frac{5}{4}[/tex]
Step 3: Divide 2 (from 2x) by 2 and square the result and add that to both sides of the equation.
2/2 = 1 1 squared = 1
[tex]x^{2} + 2x + 1 = \frac{5}{4} +1 = \frac{9}{4}[/tex]
Step 4: Factor the left side
[tex](x + 1)^{2} = \frac{9}{4}[/tex]
Step 5: Take the square root of both sides
x + 1 = ±[tex]\sqrt{\frac{9}{4} }[/tex] = ± [tex]\frac{3}{2}[/tex]
Step 6: Move the 1 to the right side and add the results
x = -1 ± [tex]\frac{3}{2}[/tex] = -1 + [tex]\frac{3}{2}[/tex] or -1 - [tex]\frac{3}{2}[/tex]
= [tex]\frac{1}{2}[/tex] or - [tex]\frac{5}{2}[/tex]
And bingo, you have the solutions by completing the square. Lot of fun, huh.

2(3x -8y) - 6 =
Answer:
6x - 16 y -6
Step-by-step explanation:
okay so first you have to distribute the 2 to the number inside the parenthesis
2(3x-8y) -6
you do 2 x 3x, which is 6x
then 2 x -8y, which is -16y
Now the new equation is 6x - 16 y -6
There you go!!
what is the value of the expression
(r − 29) ÷ 7
Answer: Answer is 8! Brainleist pls :D
Please help! The question and answer choices are attached.
Answer:
A
Step-by-step explanation:
We want to find the equation of the line in slope-intercept form.
From the graph, we are given the two points (-5, 1) and (0, -3).
We can find the slope between them. The slope formula is given by:
[tex]\displaystyle m=\frac{y_2-y_1}{x_2-x_1}[/tex]
We will let (-5, 1) be (x₁, y₁) and (0, -3) be (x₂, y₂). Substitute:
[tex]\displaystyle m=\frac{(-3)-(1)}{(0)-(-5)}[/tex]
And evaluate:
[tex]\displaystyle m=\frac{-4}{5}=-\frac{4}{5}[/tex]
Next, notice that the point (0, -3) is already the y-intercept, so we do not need to find it.
Slope-intercept form is given by:
[tex]\displaystyle y=mx+b[/tex]
Therefore, our equation is:
[tex]\displaystyle y=-\frac{4}{5}x-3[/tex]
Our answer is A.
