If you chose to use substitution to solve this system what should your equation look
like?
y=5x-5
y= -4x+22
Step-by-step explanation:
y=5x-5
y= -4x+22
1- use y=5x-5 solve for y (here you don't really have to do anything)
This stays the same, Therefore y = 5x-5
2- you will substitute y=5x-5 for y in y= -4x+22. The problem should now look like this:
5x-5= -4x+22
Solving for xnow, with the equation above you will solve for x-
5x-5= -4x+22 (add 4x to both sides)
9x-5= 22 (add 5 to both sides)
9x=27 (divide by 9)
x=3
Solving for yNow that you Know that x=3 you can substitute x=3 for x in y=5x-5. The problem should look like this:
y= 5(3)-5
Now with the equation above you can solve for y
y= 5(3)-5 (multiply 5 by 3)
y= 15-5 (subtract)
y=10
Now you have your answers X=3 Y=10

Two streets form an intersection. C and D are supplementary
angles. If the measure of C is 140° and the measure of D is
two times the value of x, what is the value of x?
Answer:
20degrees
Step-by-step explanation:
The sum of angle C and D is 180 degrees since they are supplementary
Given
m<C = 140 degrees
m<D = 2x
Taking the sum and equating to 180
140 + 2x = 180
2x = 180-140
2x = 40
x = 40/2
x = 20 degrees
Hence the value of x is 20degrees
Please help, will give brainliest if the equation is added.

Write a function in terms of t that represents the situation.
Sales of $10,000 increase by 65% each year.
y =
13
Answer:
A function in terms of t that represents the situation is:
[tex]\:y\:=\:10,000\left(1.65\right)^t[/tex]
Step-by-step explanation:
We know that the exponential growth function is of the form
[tex]y\:=\:a\:\left(1\:+\:r\right)^t[/tex]
Here:
a = initial value r = growth rate t = number of time intervals that have passedAs the sales of $10,000 represent an initial condition. Thus,
a = 10,000
Given that sales are increased by 65% every year.
r = 65% = 0.65
now substituting a = 10,000 and r = 0.65 in the function
[tex]y\:=\:10,000\left(1\:+\:0.65\right)^t[/tex]
[tex]\:y\:=\:10,000\left(1.65\right)^t[/tex]
Therefore, a function in terms of t that represents the situation is:
[tex]\:y\:=\:10,000\left(1.65\right)^t[/tex]

Step-by-step explanation:
one of these students is chosen at random. what is the probability of picking a student who scored above 65
Answer:
7/18
Step-by-step explanation:
7 students received a score greater than 65, out of a total of 18 students
The probability of picking a student who scored above 65 is 1/3 when one of these students is chosen at random.
To calculate the probability of picking a student who scored above 65, we need to determine the number of students who scored above 65 and divide it by the total number of students.
Looking at the given marks:
46, 65, 54, 57, 62, 73, 73, 47, 69, 48, 63, 68, 55, 48, 58, 71, 76, 70
We can see that the marks above 65 are: 73, 73, 69, 68, 76, 70 (a total of 6 marks).
Now, let's calculate the probability:
Probability = Number of favorable outcomes / Total number of outcomes
Number of favorable outcomes (students who scored above 65) = 6
Total number of outcomes (total number of students) = 18
Probability = 6 / 18
Simplifying the fraction:
Probability = 1 / 3
Therefore, the probability of picking a student who scored above 65 is 1/3.

Answer:55
Step-by-step explanation:
the distance between the two points rounding to the nearest tenth
(-8,-6) and (-3,-4)
Answer:
5.4
Step-by-step explanation:
To find the distance between two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], plug them into the following equation:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(-3-(-8))^2+(-4-(-6))^2}[/tex]
Two negatives make a positive
[tex]d=\sqrt{(-3+8)^2+(-4+6)^2}\\d=\sqrt{(5)^2+(2)^2}\\d=\sqrt{25+4}\\d=\sqrt{29}\\d=5.4[/tex]
Therefore, the distance between the two points rounded to the nearest tenth is 5.4.
