-6 +8x = -38
8x = -32
x = -4
I did this by first adding 6 to both sides to get 8x by itself. I then divided by 8 to get x by itself. I remembered to use the - - + rule (Two negatives make a positive, a positive and a negative make a negative). Hope this helps!
The y-intercept = 127 and the slope = -10
<h3>How to determine the y-intercept and the slope?</h3>
The function is given as:
y = 127 - 10x
A linear function is represented as:
y = c + mx
Where
c = the y-intercept
m = slope
This means that:
y-intercept = 127
slope = -10
The y-intercept implies that, the initial amount of water is 127 ounces and the slope implies that the water leaks by 10 ounces per minute

<u>Complete question</u>
The amount of water in a leaky bucket is given by the linear function y = 127 - 10x, where y is in ounces and x is in minutes. Find and interpret the slope and y-intercept of the linear equation.
Answer:
27. (2x + 3)(x + 5)
Step-by-step explanation:
27.
Use the 'ac' method
a*c = 2 * 15 = 30
We need 2 numbers whose product is 30 and whose sum is 13.
3 and 10 look good so we write
2x^2 + 10x + 3x + 15
= 2x(x + 5) + 3(x + 5)
= (2x + 3)(x + 5) answer
All you do is write the problem as a rate, a speed and you'll obtain the answer:
4p/4m
4/4 = 1

Hope it helped,
Happy homework/ study/ exam!
Step-by-step explanation:
Given that,
No. of heads = 40
No. of tails = 60
We know that,
Probability = (no. of favourable outcomes)/(total no. of outcomes)
Experimental probability of getting heads,
no. of favourable outcomes = 40
Total no. of outcomes = 40+60 = 100
So,
She has taken 60 on denominator. She should have taken 100 instead of 60.
