[Help Asap] For each ordered pair, determine whether it is a solution to the system of equations.
Answer:
(-4,-4)
Step-by-step explanation:
6x - 7y = 4
6(-4) - 7(-4) = 4
-24 + 28 = 4
4 = 4 This is correct to the first equation.
Now let us try the second equation.
-5x + 3y = 8
-5(-4) + 3(-4) = 8
20 - 12 = 8
8 = 8 This is also correct to the second equation.
Hope this helps, thank you !!
Olivia has a points card for a movie theater. She receives 25 rewards points just for signing up. She earns 7.5 points for each visit to the movie theater. She needs 130 points for a free movie ticket. How many visits must Olivia make to earn a free movie ticket?
Answer:
14
Step-by-step explanation:
7.5x + 25 = 130
-25 -25
7.5x = 105
[tex]\frac{7.5x}{7.5}=\frac{105}{7.5}[/tex]
x = 14
Hence, she must make 14 visits in order to earn a free movie ticket.

A cone has volume 3. If the cone's radius is 1. what is its height?
2.87 units
The volume of a cone is found by using the formula, V = (1/3)(pi)(h)r^2
Substituting values:
3 = (1/3)(3.14)(h)(1)
2.87 = h
I would love some help :)

Select the solution(s) of log2x=1−log(x+4).
Step-by-step explanation:
log2x = 1 - log(x+4)
log2x = log10 - log(x+4)
log2x = log[10/(x+4)]
2x = 10/(x+4)
2x(x+4) = 10
2x² + 8x - 10 = 0
÷2 both sides of equation
x² + 4x - 5 = 0
(x+5)(x-1) = 0
x = -5, 1
x isn't be -5 because logA, A need to be > 0
So, x value is 1

A plant is already 54 centimeters tall, and it will grow one centimeter every month. The plant's height, H (in centimeters), after M months is given by the following.
What is the plant's height after 13 months?
Answer:
67 cm
Step-by-step explanation:
We are given the initial height of the plant let's call it H.
H = 54 cm. This is the original height of the plant at M(months) = 0.
We are given that it grows at 1 cm/month. This is the rate of growth.
Rate = 1
Time (M) is given in Months.
So when M = 0, H = 54
Let's say M = 1, That is one month has passed. In this time the plant's height would have increased by 1 cm. So our plant's height would be H = 54+1 = 55 cm.
When Two months have passed our plant's height would be H = 54 + 2 = 56 cm , since every month our plant gains 1 cm in Height, we can make a fuction for this.
H = 1M + 54.
Now we just plug in 13 for M, to get 13 months.
H = 13 + 54
H = 67 cm
So our plant would be 67 cm in height after 13 months.

x = 132º
Which of the following inequalities is the solution to the number line?
Answer:
A
Step-by-step explanation:
- 5x + 4 > 9 ( subtract 4 from both sides )
- 5x > 5
Divide both sides by - 5, reversing the symbol as a result of dividing by a negative quantity.
x < - 1
Which is represented by the given number line
4 + 6 (3) + 2(5 1/2 - 1)
