What is the solution to the system of equations?
{y=5x−10y=−3x+14
Answer:
x = 3 and y = 5
Step-by-step explanation:
Given equations are :
y=5x−10 ..(1)
y=−3x+14 ...(2)
Subtract equation (2) from (1).
y-y = 5x−10-(−3x+14)
0 = 5x-10+3x-14
0= 8x-24
8x = 24
x = 3
Put the value of x in equation (1).
y=5(3)−10
= 15-10
y = 5
So, the values of x and y are 3 and 5 respectively.

Solve the following rational equation plz help!!
Answer:
x = [tex]\frac{9}{4}[/tex]
Step-by-step explanation:
Given
[tex]\frac{4x}{x+1}[/tex] - [tex]\frac{5}{x}[/tex] = [tex]\frac{4}{x^2+x}[/tex] ← factor denominator
[tex]\frac{4x}{x+1}[/tex] - [tex]\frac{5}{x}[/tex] = [tex]\frac{4}{x(x+1)}[/tex]
[ x ≠ 0, x ≠ - 1 as these would make the terms undefined ]
Multiply through by x(x + 1)
4x² - 5(x + 1) = 4
4x² - 5x - 4 = 4 ( subtract 4 from both sides )
4x² - 5x - 9 = 0 ← in standard form
(x + 1)(4x - 9) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = - 1
4x - 9 = 0 ⇒ 4x = 9 ⇒ x = [tex]\frac{9}{4}[/tex]
However, x ≠ - 1 for reason given above, then
solution is x = [tex]\frac{9}{4}[/tex]
Which graph represents the solution to the compound inequality?
–6 < 3x – 12 ≤ 9
Answer:
second graph
Step-by-step explanation:
Solving the inequality
- 6 < 3x - 12 ≤ 9 ( add 12 to all 3 intervals )
6 < 3x ≤ 21 ( divide the intervals by 3 )
2 < x ≤ 7
The graph has an open circle at 2 and a closed circle at 7
This is represented on the second graph

The average of a list of 4 numbers is 90.0 . A new list of 4 numbers has the same first 3 numbers as the original list, but the fourth number in the original list is 80 , and the fourth number in the new list is 96 . What is the average of this new list of numbers?
Answer:
94
Step-by-step explanation:
Average = sum of numbers / number of items in the set
for the first list, the average is 90 and there are four numbers, the sum of the numbers is 90 x 4 = 360
If the 4th number is 80, the sum of the first 3 numbers = 360 - 80 = 280
so the sum of the first three numbers on the second list is 260. The fourth number is 96. The sum of the numbers = 280 + 96 = 376
Average of the new list = 376 / 4 = 94
A fruit punch recipe requires 2 cups of grape juice for every 3 cups of apple juice. How
many cups of apple juice will you need if you use 9 cups of grape juice? Use a double
number line to help you answer the question. (4)
Answer:
9 cups of grape juice = 10 cups of apple juice.
Step-by-step explanation:
2 cups of grape juice = 3 cups of apple juice
9 cups of grape juice = ? cups of apple juice
9-2=7 cups of grape juice
3+7=10 cups of apple juice
9 cups of grape juice = 10 cups of apple juice.
Does the point (4, 25) satisfy the equation y = 7x + –3?
Answer:
yes, point (4, 25) satisfies the equation y = 7x + –3
Step-by-step explanation:
to see if the point satisfies the equation, we need to plug in the x coordinate to get y
if y is equal to the y-coordinate, then the point satisfies the equation
if y does not equal the y-coordinate, then the point does not satisfy the equation:
y = 7(4) + - 3
y = 28 + -3
y = 25
does 25 = 25? Yes! so the point satisfied the equation
Answer:
yes
Step-by-step explanation:
7(x)- 3 = y
7(4) - 3 = (y)
28 - 3 = 25

If x + 3 = 13, then the value of 5x – 74 is
Answer:
-24
Step-by-step explanation:
We are given two equations and are asked to solve if one equals a certain amount to the other.
Let's focus on x + 3 = 13, we need to first figure out what is x. Which is very simple, what plus 3 equals 13?
10 of course, therefore x = 10, and we can implement into the other equation.
5x - 74
Since x = 10, we can substitute x with 10 and then multiply.
5(10) - 74
50 - 74
What is 50 - 74?
-24

Ocean waves crash on the beach at a
velocity of 4.4 m/s. If the distance
between the crest of each wave is 4m,
find the frequency of the waves.
Answer:
f = 1.1 Hz
Step-by-step explanation:
Given that,
The velocity of an ocean wave, v = 4.4 m/s
The distance between the crest of each wave is 4 m.
We need to find the frequency of the waves.
The distance between the crest of a wave is called the wavelength of a wave.
The relation between the frequency, wavelength and the velocity of a wave is given by :
[tex]v=f\lambda\\\\f=\dfrac{v}{\lambda}\\\\f=\dfrac{4.4}{4}\\\\f=1.1\ Hz[/tex]
So, the frequency of the waves is 1.1 Hz.
