Answer:
y = x -2
Step-by-step explanation:
Slope = 1
(-6 , -8)
y - y₁ = m(x - x₁)
y - [-8] = 1(x - [-6] )
y + 8 = x + 6
y = x + 6 - 8
y = x - 2

B y = -3.x + 3
Answer:
A. y = -⅓x + 3
Step-by-step explanation:
Find the equation of the graph bin slope-intercept form, y = mx + b. Where,
m = slope = ∆y/∆x
Using two points on the line, (0, 3) and (3, 2),
Slope (m) = (2 - 3)/(3 - 0) = -1/3
m = -⅓
b = y-intercept = 3 (the y-coordinate of the point where the line crosses the y-axis)
✅To write the equation, substitute m = -⅓ and b = 3 into y = mx + b
Thus:
y = -⅓x + 3

Answer:
7. [tex]c = 15.81[/tex]
8. [tex]b = 16[/tex]
Step-by-step explanation:
Required
Determine the third sides
(7): We have
[tex]b = 5[/tex]
[tex]a = 15[/tex]
[tex]c=??[/tex]
To find c, we make use of Pythagoras theorem
[tex]c^2 = a^2 + b^2[/tex]
[tex]c^2 = 5^2 + 15^2[/tex]
[tex]c^2 = 250[/tex]
[tex]c = \sqrt{250[/tex]
[tex]c = 15.81[/tex]
(8): We have
[tex]c = 20[/tex]
[tex]a = 12[/tex]
[tex]b = ??[/tex]
To find c, we make use of Pythagoras theorem
[tex]c^2 = a^2 + b^2[/tex]
[tex]20^2 = 12^2 + b^2[/tex]
[tex]400 = 144 + b^2[/tex]
[tex]b^2 = 400 - 144[/tex]
[tex]b^2 = 256[/tex]
[tex]b = \sqrt{256[/tex]
[tex]b = 16[/tex]

Answer:
1) Rotation
2) Reflection
3)Dilation
4) Rotation
5) Reflection
6) Translation
7) Rotation
Step-by-step explanation: :
Keep in mind
Reflection is a flip.
Rotation turns a figure through an angle about a fixed point called the center.
Translation "slides" an object a fixed distance in a given direction.
Dilation is a transformation that produces an image that is the same shape as the original, but is a different size.
9x+10y =1 9x-6y=-15 solve using elimination
Answer:
I. x = -1
II. y = 1
Step-by-step explanation:
Given the following algebraic expressions;
9x + 10y = 1 .......equation 1
9x - 6y = -15 ......equation 2
To solve using the elimination method, we would subtract eqn 1 from eqn 2.
(9x - 9x) + (-6y - 10y) = (-15 - 1)
0x - 16y = -16
-16y = -16
16y = 16
y = 16/16
y = 1
Next, we would find the value of x;
From eqn 1;
9x + 10y = 1
Substituting the value of y, we have;
9x + 10(1) = 1
9x + 10 = 1
9x = 1 - 10
9x = -9
x = -9/9
x = -1
15% of customers that come to your
taco truck order two tacos. If 300 guests
come to your store, how many of them
will you expect to order two tacos?
Answer:
Number of customers (double taco)= 45
Step-by-step explanation:
Giving the following information:
Double taco order rate= 15% = 0.15
Total number of customers= 300
To calculate the number of customers that order two tacos, we need to use the following formula:
Number of customers (double taco)= Double taco order rate*total number of taco
Number of customers (double taco)= 0.15*300
Number of customers (double taco)= 45
NK Karate Club offers two different fees for their karate classes. Club members are charged a one-time membership fee of $32 and pay $4 per class. Non-members pay $8 per class. Let y represent the number of karate classes attended.
a. Write an expression to represent the cost for a non-member to attend y classes.
b. Write an expression to represent the cost for a member to attend y classes.
c. Set the two expressions equal to each other and solve the equation to determine how many classes result in the same cost for a member and non-member.
Answer:
a) x = 8y
b) x = 32 + 4y
c) 8y = 32 + 4y
Step-by-step explanation:
-4y -4y
8y = 32 + 4y
÷4 ÷4
4y = 32
y = 32
The expression represents the cost for a non-member to attend y classes is x=8y.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
Given that, Club members are charged a one-time membership fee of $32 and pay $4 per class. Non-members pay $8 per class.
Let y represent the number of karate classes attended.
a) The cost for a non-member to attend y classes is
Non-members pay $8 per class.
So, the expression is 8y
b) The cost for a member to attend y classes is
Club members are charged a one-time membership fee of $32 and pay $4 per class.
Now, the expression is 32+4y
c) Set the two expressions equal to each other, that is
8y =32 + 4y
8y-4y=32
4y=32
y=8
Therefore, the expression represents the cost for a non-member to attend y classes is x=8y.

LifeCharge Batteries claims that their batteries last an average of 210 hours when used in a hand held gaming system, with a standard deviation of about 9 hours. An independent quality control company took a sample of 34 batteries, and used the same hand held gaming system that LifeCharge used to record the time the batteries lasted.
1. Assuming the claim is true, what is the probability that the value of the sample mean is greater than 251.7 hours.
2. The sample mean was found to be 251.7, what does this say about the claim?
A. The sample mean is quite far off from the mean claimed, casting doubt on the current mean.
B. The sample mean is sufficiently close to the mean claimed, supporting the current mean.
C. The sample mean found does not truly support nor cast doubt on the current mean.
Answer:
The answer is "0.0023 and Choice a"
Step-by-step explanation:
In point a:
The central limit theorem:
[tex]\mu_{X}= 250\\\\\sigma_{X}=\frac{\sigma}{\sqrt{n}}=\frac{6}{\sqrt{100}} =0.6\\\\P(\bar{X}>251.7)\\\\=P(z>\frac{251.70-250}{0.6})\\\\=P(z>2.83)\\\\=1-0.9977\\\\=0.0023[/tex]
In point b:
The chance is lower than 0.05. This means that it is very rare to see the average sample above 251.8 if the argument is valid, that is why the means of the sample is far away from the common claimed and casts doubt on the actual mean.

Question:
Which of the following is a quadrantal angle?
a) π/2 b) π/3 c) 2π/3 D) 4π/5
Answer:
[tex](a)\ \frac{\pi}{2}[/tex]
Step-by-step explanation:
Required
Which of a to d is a quadrantal angle
An angle is said to be quadrantal if and only if the angle has its terminal side on the x or y axis.
Such angles (in degrees) are: 90, 180, 270, etc.
So, we have:
[tex](a)\ \frac{\pi}{2}[/tex]
[Convert to degrees]
[tex]\frac{\pi}{2} = \frac{180}{2}[/tex]
[tex]\frac{\pi}{2} = 90[/tex]
Hence:
[tex](a)\ \frac{\pi}{2}[/tex] is a quadrantal angle
