Y=mx+b
2y-3x=7
2y=3x+7
y=3/2x+7/2
slope(m) = 3/2
In order to find the Y intercept you have to have at least one pair of coordinates from the line and plug it into the slop intercept formula OR you can just look at y=3/2x+7/2 on a graph to see where the line crosses the y-axis with the x value of zero , unfortunately I don't have a graphing calculator and you did not provide coordinates but hopefully this helped c: !
Answer:
cups of sugar.
Step-by-step explanation:
We have been given that Sabrina is baking cookies the recipe calls for 3/4 of a cup of sugar. Sabrina needs to double the recipe because she has a large cookie loving family.
To find the amount of sugar needed for recipe, we need to multiply 3/4 by 2 as:
![\text{Sugar needed for double recipe}=2\times \frac{3}{4}](https://tex.z-dn.net/?f=%5Ctext%7BSugar%20needed%20for%20double%20recipe%7D%3D2%5Ctimes%20%5Cfrac%7B3%7D%7B4%7D)
![\text{Sugar needed for double recipe}=1\times \frac{3}{2}](https://tex.z-dn.net/?f=%5Ctext%7BSugar%20needed%20for%20double%20recipe%7D%3D1%5Ctimes%20%5Cfrac%7B3%7D%7B2%7D)
![\text{Sugar needed for double recipe}=\frac{3}{2}](https://tex.z-dn.net/?f=%5Ctext%7BSugar%20needed%20for%20double%20recipe%7D%3D%5Cfrac%7B3%7D%7B2%7D)
![\text{Sugar needed for double recipe}=1\frac{1}{2}](https://tex.z-dn.net/?f=%5Ctext%7BSugar%20needed%20for%20double%20recipe%7D%3D1%5Cfrac%7B1%7D%7B2%7D)
Therefore, Sabrina needs
cups of sugar.
You do them in the order of operations, for example, on the 1st one you did 3x5 first and got 15, and then you added 2 and got a total of 17. On the second one, you did2x4 which is 8 and the you added 3 and made it a total of 11. So basically you do the last 2 boxes first, the add/subtract the first from the total of the other 2.
Answer:
OB - Older Brother
YB - Younger Brother
A) OB -YB = 4
B) OB * YB = 96
B) OB = 96 / YB
Multiplying A) by -1
A) -OB + YB = -4 then we add B)
B) OB = 96 / YB
YB = -4 + 96 / YB
Multiplying both sides by YB
YB^2 = -4YB +96 then re-arranging
YB^2 + 4YB -96 = 0 solving by quadratic equation
AS OF 5 years AGO:
Younger Brother's age = 8
Older Brother's age = 12
NOW THEIR AGES ARE:
8 + 4 = 12 YB and
12 + 4 = 16 OB
