I just learn this but I forgot
Answer:
Step-by-step explanation:
leading coefficient of 1 ==> a=1
sum of roots= 7+(-5)=2 ==> b= - 2
Product of roots=-35 ==> c=-35
Formula is<u> y=x²-2x-35</u>=(x-7)(x+5)
Answer:
s = 2t
Step-by-step explanation:
At the end of a snow storm, Audrey saw there was a lot of snow on her front lawn. The temperature increased and the snow began to melt at a steady rate. There was a depth of 10 inches of snow on the lawn when the storm ended and then it started melting at a rate of 2 inches per hour. Write an equation for S, in terms of t, representing the depth of snow on Audreys lawn, in inches, t hours after the snow stopped falling.
2 inches = 1 hour
10 inches = x hour
2x = 10
x = 10/2
x = 5
Creating an equation
S ∝ t
S = kt
k = s/t
k = 2/1
k = 2
The equation for S, in terms of t, representing the depth of snow on Audreys lawn, in inches, t hours after the snow stopped falling is
S = 2t
Step-by-step explanation:
1. 3 and 2 are complementary because when you add them up, they give a toral of 90°.
2. As you may tell from the picture, and that they stated it in the question, angles 1 and 2 are added and they give a total of 90°.
3. If we consider that angle 3 is somewhat equal to angle 1, then the statement is true.
4. As I mentioned, if angle 1 and angle 3 are equal, then the statement is also true.
5. It was kind of proven above that angle 1 and angle two are similar, so this is true.
6. Like option 5, this is also the same thing.
I hope it helped!
