Answer:
<u>4y = x + 13</u>
Step-by-step explanation:
The general equation of the line y = mx + c
where m is the slope and c is constant represent y-intercept
The line shown in the graph pass through the points (3,4) , (-1,3)
The slope of the line = (y₂-y₁)/(x₂-x₁) = (3-4)/(-1-3) = -1/-4 = 1/4
∴ y = (1/4) x + c
Substitute with the point (3,4) to find c
∴ 4 = (1/4) 3 + c
∴ c = 4 - 3/4 = 13/4
∴ y = (1/4) x + 13/4 ⇒ multiply both sides by 4
∴ 4y = x + 13
So, The equation of the line in the graph: 4y = x + 13
The equation can be written as <u>y = (1/4) x + 13/4 OR 4y - x = 13</u>
Answer: George receive 44 % of his full dose .
Step-by-step explanation:
Given : The amount for full dose : 25 grams
The amount received by George = 11 grams
Now, the percent of his full dose received by George :-
Hence, George receive 44 % of his full dose .
Answer:
Step-by-step explanation:
The first plan has no initial fee. If the unknown is the number of miles driven, then the equation for the first plan is
C(x) = .7x
The second plan has a fee plus mileage, so with the unknown again being the number of miles driven, then the equation for the second plan is
C(x) = .6x + 75
If we are looking to solve for the number of miles when the cost is the same, we set the cost functions equal to each other and solve for x:
.7x = .6x + 75 and
.1x = 75 so
x = 750
This is really a very helpful thing to be able to figure out, because if you use the first plan and want to drive MORE than the 750 miles, you will be paying more than if you want to drive more than the 750 miles and choose the second plan. For miles less than 750 plan one is cheaper, for miles greater than 750 plan two is cheaper.
See, there really IS a reason for all this algebra!!
Answer:
Well I can't see the Coordinate lane but ill still help you as much as I can.
Step-by-step explanation:
The very first thing you want to do is look at the number you are working on. Then, look at the x axis it's the one that is sideways like a person laying down. Make an invisible line in your head between where the number you are working on meets the x-axis. After that you are going to look at the y-axis it is the one that looks like a person standing up.Make an invisible line in your head between where the number you are working on meets the y-axis.
I'm sorry I couldn't see your paper hopefully this helps a little
-6+-7 is the correct answer
