Answer:
x = -8
Step-by-step explanation:
x = 2y - 4 --- Equation 1
7x + 5y = -66 --- Equation 2
I will be using the substitution method to solve this.
Substitute x = 2y - 4 into Equation 2:
7x + 5y = -66
7(2y - 4) + 5y = -66
Evaluate.
14y - 28 + 5y = -66
Evaluate like terms.
19y - 28 = -66
Isolate 19y.
19y = -66 + 28
= -38
Find y.
y = -38 ÷ 19
y = -2 --- Equation 3
Substitute y = -2 into Equation 1:
x = 2y - 4
x = 2(-2) - 4
Evaluate.
x = -4 - 4
x = -8
Answer:
max wil sell 52 because the first hour he sold 12 5hours -1 hour = 4 hour
4 hour × 10 p/h= 40
max sold 12+40 =52
leah will sell 58 because the first hour she sold 8
5hours - 1hour = 4 hours
4hours× 10 glasses p/h = 40
leah sold 40+8 =48 glasses
Answer:
it would depend on what time is(hours, minutes)
Step-by-step explanation:
But its 6 dollars per H
The least likely measure of central tendency to be used would be; The range.
<h3>How to identify measures of central tendency?</h3>
We are given the points scored by the basketball team as;
84, 67, 74, 87, 67, 73
Now, the three major measures of central tendency are mean, median and mode.
Mean is the average while mode is the most frequent item while median is the middle term when arranged in ascending order.
However, when discussing their year, what the paper would like to know is their average amount of points per game for the year and as such he will use the mean.
However, the least likely measure of central tendency to be used would be the range.

Answer:
Step-by-step explanation:
We are going to find the slope by lining up the points vertically and subtract, then put 2nd difference over first.
Also you could just use 
. It is the same thing.
( 5 , 5)
-( 1 , 3)
--------------
4 2
So the slope is 2/4 or 1/2 after reducing.
The point-slope form a line is
with a point on the line 
given and with slope 
given.
We are going to solve this for y and simplify what we can because our goal is y=mx+b; this is slope-intercept form. It is called that because it tells us the slope,m, and the y-intercept,b.
Distribute:
Add 3 on both sides:
Simplify:
