Step-by-step explanation:
Answer:
Part A: the answer is $3.70 (A)
Part B: the answer is $38.60 (D)
Step-by-step explanation:
The x-intercept of a line is when the y coordinate is equal to 0. So, the x-intercept would be (0,-7).
The y-intercept of a line is when the x coordinate is equal to 0. So the y-intercept would be (-5,0).
To find the equation of a line, you need the slope and the y-intercept.
We already know the y intercept is -5. The equation for a line is:
Y=mx+b
m stands for slope
b stands for the y intercept.
To find the slope, use the equation-
y1-y2
--------
x1-x2
Another way to say that is the change in y over the change in x.
Plug in the the 2 coordinate points you know, which are (-7,0) and (0,-5).
0+5
-------,
-7-0
5/-7.
The slope is 5/-7
The Y intercept is -5
The equation of the line is y= 5/-7x -5
The coordinate point for the x intercept is (-7,0)
The coordinate point for the y intercept is (0,-5)
Question
<em>Emerson is making a punch that contains 60% grape juice and the rest lemon-lime soda. The punch has 2 liters of lemon-lime soda. Part A: Write an equation using one variable that can be used to find the total number of liters of grape juice and lemon-lime soda in the punch. Define the variable used in the equation and solve the equation. Hint: 0.6x represents the number of liters of grape juice in the punch. (5 points) Part B: How many liters of grape juice are present in the punch? Show your work. (5 points)</em>
Answer:
<u>5l = 0.4l(1) + 0.6l(2)</u>
<h2>
Step-By-Step-Explenation </h2>
5l = Total litres.
0.4l = 0.4 represents % of lemon-lime soda in litres.
0.6l = 0.6 represents % of grape juice in litres.
For grape juice, make L(1) = 0 and find for L(2), you will get 3L
For lemon-lime soda, make L(2) = 0 and find for L(1), you will get 2L
3L + 2L = 5L.
60% + 40% = 100%
I think this is right but i really tried.!
Hope this helps!
