Answer:
For 5 packets of flavoring, ounce of water = 60.
For 84 ounces of water, number of packets of flavoring = 7.
For 10 packets of flavoring, ounce of water = 120.
For 144 ounces of water, number of packets of flavoring = 12.
Step-by-step explanation:
From the table, it is clear that the ratio between the packets of flavoring to ounce of water is 2:24 = 1:12.
So, for 5 packets of flavoring, ounce of water = 5 × 12 = 60.
For 84 ounces of water, number of packets of flavoring = 7 × 1 = 7.
For 10 packets of flavoring, ounce of water = 10 × 12 = 120.
For 144 ounces of water, number of packets of flavoring = 12 × 1 = 12.
Please refer to the attached table.
Answer:
3x + y = 20 and x - 2y = - 4
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
(a)
Given
3x + y = 17 ( subtract 3x from both sides )
y = - 3x + 17 ← in slope- intercept form
with slope m = - 3
Para;;el lines have equal slopes , then
y = - 3x + c ← is the partial equation
To find c substitute (4, 8) into the partial equation
8 = - 12 + c ⇒ c = 8 + 12 = 20
y = - 3x + 20 ← in slope- intercept form
Add 3x to both sides
3x + y = 20 ← in standard form
--------------------------------------------------------
(b)
Given
y + 2x = 13 ( subtract 2x from both sides )
y = - 2x + 13 ← in slope- intercept form
with slope m = - 2
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
=
, then
y = x + c ← is the partial equation
To find c substitute (2, 3) into the partial equation
3 = 1 + c ⇒ c = 3 - 1 = 2
y = x + 2 ← in slope- intercept form
Multiply through by 2 to clear the fraction
2y = x + 4
x - 2y = - 4 ← in standard form
Answer:
Okay so i use this all the time for my school so it graphs thing like functions, coordonates it also has a way you can add a table if u need it, to basically use it enter the y in ur equation like y=8x+9 and then the next bar would be x like x=9x+10 things like that and to graph a function u only need one bar and such to graph it that way, i'll put down some examples for you to look at and if u have any specififc questions i can answer those as well, Oh also if u put up 2 equations and only see one line you have to click the zoom out button on the right side of ur screen until u see the line.
Step-by-step explanation:
In the first picture i circled the important parts of the calculator which is the zoom out button, and the colors of the lines, you can also switch the colors if u want to as well, In the second picture it shows how to find the x,y intercepts if thats what you have to do. Whenever the lines intercept on a graph then thats what ur x and y intercepts are. If you have any more questions pls ask and i can answer them!
