1st Equation: x= -3/2y-3
2nd Equation: x=-(10y+18)/7
Step by Step Explanation:
1st Equation: since "solve" usually means to find x unless told to solve for another variable, we are going to isolate x in both equations
-24-8x=12y (add 24 to both sides)
+24 +24
-8x=12y+24 (isolate 8 from x)
/-8 /-8
x=-3/2y-3 [simplify fractions (-12/8 turns to -3/2)]
2nd Equation:
1+10/18y=-7/18x
1+10/18y=-7/18x (convert 5/9 to 10/18 to divide)
1+10/18y=-7/18x (isolate -7/18 from x)
/-7/18 /-7/18
(to make this easier on ourselves)
-(10y+18)/7=x
OR
-18/7-10/7y=x

Which of the following elevations is less than negative -5 feet from sea level?
A)negative -10 feet
B)negative-3 feet
C) positive 2
D) positive 5 feet
Answers
Solution:
An elevation of -10 ft would be less than -5 ft from sea level.
(NOTE) When it comes to negative integers on a number line, just keep in mind that the closer to 0 the negative integer is, the greater in value it becomes. However, the further away from the zero mark the integer is, the value decreases/is a smaller number.
This being said, lets look at the given options.
A) -10 feet ← Notice when you place -10 on the number line, the point is far to the left of the zero mark, as well as -5. This being said, this most likely means that this is a lesser elevation level than that of -5 feet from sea level.B) -3 feet ← Notice when you place -3 on the number line, the point is also to the left of the zero mark, however it is ahead of -5. This being said, this elevation is not lesser than -5 feet from sea level, and hence not the correct choice.C) 2 feet ← Notice when you place 2 on the number line, the point is just to the right of the zero mark and is definitely ahead of -5 feet. This means that this elevation is not lesser than -5 feet from sea level, and hence is not the correct choice.D) 5 feet ← Notice that when you place 5 on the number line, the point is to the right of the zero mark and is definitely also ahead of -5 feet. This being said, this means that this elevation is not lesser than -5 feet from sea level, and hence is not the correct choice.Hence, in conclusion to all of this, our correct choice would be A) -10 feet, considering it is the only elevation that is less than -5 feet from sea level.

the ratio of the number of oranges to apples to bananas is 8:5:2. if there are 120 fruits in total, how many bananas are there
Answers
Answer:
Step-by-step explanation:
To find the number of bananas, we need to determine the proportion of bananas in the total number of fruits based on the given ratio.
Let's assume that the ratio of oranges, apples, and bananas can be represented by 8x, 5x, and 2x, respectively, where x is a common multiplier.
The sum of the parts in the ratio is 8x + 5x + 2x = 15x.
We know that the total number of fruits is 120. Therefore, we can set up the following equation:
15x = 120
To solve for x, we divide both sides of the equation by 15:
x = 120 / 15
x = 8
Now that we know the value of x, we can find the number of bananas by multiplying it by the corresponding part of the ratio:
Number of bananas = 2x = 2 * 8 = 16
So, there are 16 bananas in total.
We can add all the parts to the ratio and get 15. Out of 15 parts, 2 are bananas. Now we can calculate how many fruits are in one part. One fifteenth of 120 is 8, so there are 8 fruits in one part. 2 parts are bananas, so multiplying 8 with 2 gives us our answer, 16.

Triangle JKL has vertices at J(−1, −5), K(−2, −2), and L(2, −4). Determine the translation direction and the number of units of the image of triangle JKL if vertex J′ is at (−1, −8).
3 units down
3 units up
7 units to the right
7 units to the left
Answers
Answer:
3 units down
Step-by-step explanation:
J(-1, -5) → J'(-1, -8)
The x coordinate of the vertex J is -1 and does not change in J' (it is still -1)
The y coordinate of J is -5, and for J' is -8. This means the translation direction of 3 units down. (-8- -5 = -3)

Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Answers
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500

First we start with the formula for cylinders v=(pi)r(squared)h filled in Thats v=(3.14)(8 squared) (8) which brings us to the answer 1607.68 but you must round to the nearest tenth aka 1607.7
Answer:
The first option, V ≈ 1607.7 in²
Step-by-step explanation:
Find the volume of the given cylinder.
\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)
Given:
r = 8 in
h = 8 in
π = 3.14
Find:
V = ?? in³
\(\hrulefill\)
Now solving,
Substitute the given values into the formula:
=> V = (3.14)(8)²(8)
Using a calculator to simplify:
=> V = 1607.68 in²
Rounded to the nearest tenth:
∴ V ≈ 1607.7 in²
Thus, the first option is correct.

Height of the right angled triangle is equals to 4in.
What is right angled triangle?" A right angled triangle is a two dimensional closed figure with three vertices and three angles, one of the angle should be of measure 90 degrees."
Formula used
Area of right angled triangle = ( 1 / 2) × base × height
According to the question,
Base of the right angled triangle = 18in.
Area of the right angled triangle = 36 in²
Let 'h' represents the height of the triangle
Substitute the value in the formula we have,
36 = ( 1 / 2) × 18 × h
⇒36 = 9h
⇒ h = 4in.
Hence, height of the right angled triangle is equals to 4in.

Answers
The correct answer is U′(1, −1), V′(4, 0), W′(1, 4). When a point is rotated 90° counterclockwise about the origin, the x-coordinate and y-coordinate change places, and the sign of the new x-coordinate is the opposite of the original y-coordinate. So for example, point U(−1, 1) becomes U′(1, −1).

A six-foot-tall basketball player shoots a ball towards the basket and misses. The height in feet of the ball up off the floor of the court as it travels through the air can be modeled by the function: \(h(x)=-16x^2+48x+6\) where x is the number of seconds the ball is in the air after the shot is taken. When does the ball reach its maximum height? What is the maximum height of the ball? How much time will pass in seconds from the start of the shot to the ball hitting the floor? Answer all three questions to receive full credit.
Answers
Answer:
i) The maximum height of the ball 'x' = 1.5 seconds
ii) The maximum height = 42
Step-by-step explanation:
Step(i):-
Given h(x) = - 16 x² + 48 x +6 ...(i)
Differentiating equation (i) with respective to 'x'
\(h ^{l} (x) = - 16 (2 x) +48 (1)\) ...(ii)
Equating Zero
- 3 2 x + 4 8 = 0
- 32 x = - 48
x = 1.5
step(ii):-
The maximum height of the ball 'x' = 1.5
Again Differentiating equation (ii) with respective to 'x'
\(h ^{ll} (x) = - 16 (2 x) < 0\)
The maximum height 'x' = 1.5
h(x) = - 16 x² + 48 x +6
h(1.5) = - 16 (1.5)² +4 8 (1.5) +6
= 42
The maximum height at x = 1.5 is = 42
Final answer:-
i) The maximum height of the ball 'x' = 1.5 seconds
ii) The maximum height = 42
