56 + 77
GCF = 7
56 + 77 = (7 * 8) + (7 * 11) =
7(8 + 11) <===
If you would like to know what was the average time it took Janette to fold and put away all four items, you can calculate this using the following steps:
26.1 seconds for the shirt + 24.3 seconds for the sweater + 32.8 seconds for the pants + 18.2 seconds for the scarf = 26.1 + 24.3 + 32.8 + 18.2 = 101.4 seconds
101.4 seconds / 4 items = 25.35 seconds
The average time was 25.35 seconds.
Answer:
1
Step-by-step explanation:
We are finding the discriminant of the function
It needs to be written in the form ax^2 +bx+c =0
2x^2 +3x = -1
Add 1 to each side
2x^2 +3x+1 = -1+1
2x^2 +3x+1 = -0
b^2 -4ac
a=2 b=3 and c = 1
3^2 - 4(2)(1)
9 - 8

Y = 5x + 3.....the slope here is 5. A perpendicular line will have a negative reciprocal slope. To find the negative reciprocal, we flip the original slope and change the sign. So we have slope 5 or 5/1.....flip it and it becomes 1/5....change the sign and it becomes - 1/5. So our perpendicular line will have a slope of -1/5.
y = mx + b
slope(m) = -1/5
(2,2)....x = 2 and y = 2
now we sub into the formula and find b, the y int
2 = -1/5(2) + b
2 = -2/5 + b
2 + 2/5 = b
10/5 + 2/5 = b
12/5 = b
so ur perpendicular equation is : y = -1/5x + 12/5 <==
