Answer: 8x^2° + 52x° + 27°
Using the knowledge i know i think this is the right answer
Have a great day :)
L = lemon drops
J = jelly beans
L +J = 100
L=100-J
1.90L + 1.20J=1.48*100
1.90(100-j) +1.20J =148
190-1.90J+1.20J=148
190-0.7J=148
-0.7J=-42
J = 60
L=100-60 = 40
40 pounds of Lemon Drops are needed
x+y=5
-x -x
Equals:
y=-x+5
Now you have:
y=-x+5
x-y=1
Insert -x+5 into y
x-x+5=1
Combine like terms
2x+5=1
Subtract 5.
2x=-4
Divide 2.
Answer: x=-2
Answer:
4. y = 1/2x + 3/2
Step-by-step explanation:
First, we need to change the line that's parallel into slope-intercept form.
-2x + 4y = 8
4y = 2x + 8
y = 1/2x + 2
If it's parallel, then it remains the same. So our slope is 1/2.
To find the y-intercept, you need to plug the coordinates into the equation.
y = 1/2x + b
-1 = 1/2(-5) + b
-1 = -5/2 + b
3/2 = b
y = 1/2x + 3/2
One type of display is a frequency distribution curve.
This is a graph you are probably used to seeing, and often takes the form of a bar graph.
The length of each bar indicates either the frequency or number of students within a certain salary range. It helps to get an idea of the most typical salaries students are earning in their first year.
This display is more appropriate than, say, a line graph, because the graph is not supposed to show change over time, but just a snapshot of students' salaries after graduating.
