Answer:
y = 3 + 2x
Step-by-step explanation:
In this scenario, we are given two values which are the initial height of the plant and its growth height. Then we are given a variable which is the number of months (x) that are unknown for us. The growth height needs to be multiplied by the number of months to know how much it has grown in that time period. Then we add this value to the initial height of the plant to calculate the total height (y) of the plant after x number of months. We can apply this information to form the following equation in slope-intercept form.
y = 3 + 2x
1.80 per lb for 100 lbs = 1.80 * 100 = 180
1/10 * 180 = 180/10 = $ 18 <==
Answer:
Step-by-step explanation:
Here's a completely valid trick for finding the equation of this new line:
Start with the given 2x + 4y = 6. Replace that '6' with 'C.' We need to find C. To do this, replace x with 6 and y with 4 and calculate C:
2(6) + 4(4) = C, or 12 + 16 = C. Thus, C = 28, and the desired equation is
2x + 4y = 28, or (in simplified form) x + 2y = 14
Answer: 7.5
Form your proportion. Let x be the width of QRST.
Length of ABCD Length of QRST
----------------------- = -------------------------
Width of ABCD Width of QRST
8/5 = 12/x
Solve for x by cross-multiplying.
(8)(x) = (12)(5)
8x = 60
x = 7.5
3 gallons= 10.5
5 gallons= 17.5
7 gallons=24.5
