Give the y-interecept
3x + y = 5
(Remember that to find the y-intercept, you need to make the x value a 0.)
(-3, 0)
(-3, 3)
(0, 5)
(5, 0)
Answer:
(0, 5)
Step-by-step explanation:
3x + y = 5
Plug x = 0
3*0 + y = 5
0 + y = 5
y = 5
y-intercept = (0, 5)

Math homework, a bit tired out and can't really do an equation without getting sidetracked.
Answer:
C
Step-by-step explanation:
Using Pemdas:
3 (1 + 4) / 3 + 4^2
3 (5) / 3 + 4^2
3 (5) / 3 + 16
15 / 3 + 16
Answer:
A
Step-by-step explanation:
First you have to simplify the equation, you should use PEMDAS. This means you first have to simplify the parenthesis. simplify it, multiply 3 by 1 and 4. This makes the equation 3+12/3+4^2. Then following PEMDAS, you simplify the exponent. 4^2 is the same as 4x4 so 4^2 is 16. 3+12/3+16, then you can simplify either side first. 3+12/18, then you simplify the only part left. 15/18. The GCM of this fraction is 3 so you divide both sides by 3. 15/3/18/3. Simplify this to get 5/6.
When you simplify equation A, you get 15/3/6. First simplify 15/3 to get 5. This equation answer is 5/6 which is equal to 5/6 so this is the correct answer.
When you simplify equation B, you get 15/3/8. Simplify 15/3 again and get 5. This equation answer is 5/8 which is not equal to 5/6 so this is not the correct answer.
When you simplify equation C, you get 15/3/16. Simplify 15/3 first and get 5. 5/16 is not equal to 5/6 so this is not the correct answer.
Therefore, Equation A is the correct answer.
Which equation can be used to solve for x in the following diagram?
7xº
11x°
Answer:
7x° + 11x° = 90°
(Required equation)
Step-by-step explanation:
7x° + 11x° = 90°
(complementary angles)
18x° = 90°
18x = 90
x = 90/18
x = 5

The length of AB is four times the length of BC.
AC = 75 cm.
Work out the length of AB.
Answer:
Let length of bc be x cm
Thus, ab=4x
ab+bc=ac
4x+x=75
5x=75
x=75/5
x=15
Therefore, ab=x=15cm
bc=4x=60cm

Irene has a spinner with 5 sections, each with a different color. Irene spins the spinner many times, and records the results in the table.
Color: Red Orange Yellow Green Blue
Frequency: 16 11 9 14 10
Find the probability of spinning each color, based on the data. Explain how you calculated each probability.
Step-by-step explanation:
Probability of spinning a specific colour is the frequency of the colour divided by the total frequency.
Total frequency = 16 + 11 + 9 + 14 + 10 = 60
Hence we have the following probabilities:
P(Red) = 16/60 = 4/15P(Orange) = 11/60P(Yellow) = 9/60 = 3/20P(Green) = 14/60 = 7/30P(Blue) = 10/60 = 1/6farmer johnson is planting a garden in the park. he has a square garden bed that is 21 feet long.

Perry used the formula V (t) = 24,450(1-0.13)
to find the value of his car t years after he purchased it.
What does 0.13 represent?
A the price of the new car
B the time of year the car was purchased
the value of the car after t years
a 13% decrease in value each year
Answer:
D) a 13% decrease in value each year
Step-by-step explanation:
Perry used the formula V (t) = 24,450(1-0.13)^t to find the value of his car t years after he purchased it.
What does 0.13 represent?
The expression given above represents and expression of exponential decrease.
This is represented by the formula
y = a(1 - r)^t
Where
y = Value after time t
a = Initial value
r = Rate of decrease
t = Time
Comparing both expressions
y = a(1 - r)^t = V (t) = 24,450(1-0.13)^t
We can see that:
r = 0.13
This is the rate of decrease.
Converting to Percentage = 0.13 × 100
= 13%
Option D is the correct option.
