D is the answer hope this helped but if it’s wrong i am generally sorry
Answer: 4/7
This is a fraction
---------------------------------------------------
The two points are (x1,y1) = (2,3) and (x2,y2) = (9,7)
Which breaks down to these four facts
x1=2
y1=3
x2=9
y2=7
Plug those values into the slope formula below and simplify
m = (y2 - y1)/(x2 - x1)
m = (7 - 3)/(9 - 2)
m = 4/7
The slope is 4/7
Side Note: slope = rise/run = 4/7 so rise = 4 and run = 7. Meaning that each time we go up 4, we also go to the right 7
First day, we break up the gallon into 4 quarts. So now we have 2 quarts 3 pints 1 cup.
After the second day, we end with 2 quarts 1 cup!
Answer:
2/5
Step-by-step explanation:
add all marbles together: 10 marbles
since only 4 are red, the fraction would be 4/10
4/10 can be simplified to 2/5
Answer:
x1, x2 = 4.74 , -2.74
Step-by-step explanation:
To find the roots of a quadratic function we have to use the bhaskara formula
ax^2 + bx + c
x^2 - 2x - 13
a = 1 b = -2 c = -13
x1 = (-b + √ b^2 - 4ac)/2a
x2 =(-b - √ b^2 - 4ac)/2a
x1 = (2 + √ (2^2 - 4 * 1 * (-13)))/2 * 1
x1 = (2 + √ (4 + 52)) / 2
x1 = (2 + √ 56 ) / 2
x1 = (2 + 7.48) / 2
x1 = 9.48 / 2
x1 = 4.74
x2 = (2 - √ (2^2 - 4 * 1 * (-13)))/2 * 1
x2 = (2 - √ (4 + 52)) / 2
x2 = (2 - √ 56 ) / 2
x2 = (2 - 7.48) / 2
x2 = -5.48 / 2
x2 = -2.74
