Answer
Given equation is:
x
2
−9x+20=0
⇒x
2
−5x−4x+20=0
⇒(x−4)(x−5)=0
⇒x=4andx=5
1. When x is 1, what value of y makes the equation true?
Answer:
Step-by-step explanation:
-0.5
Step-by-step explanation:
If x is 1, plug it into the equation.
So, y=-3(1) + 2.5
-3(1) = -3
now add.
-3+2.5 = -0.5
so that should give you y = -0.5

Mr. Simpson feeds his dog 1⁄2 of a cup of dog food each day. How long will 4 cups of dog food
last?
Answer: 8 days
Step-by-step explanation: Get out your calculator. Put in 1/2, did you get .5? You should've gotten .5. Now if you put in 4 / .5, then you'll get 8. Seems pretty simple I guess. Lmk if this helped you.
The dog food last for 8 days.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Mr. Simpson feeds his dog 1⁄2 of a cup of dog food each day.
Total cups of food= 4
So, 4 cups of dog food lasts
= 4/ (1/2)
= 4 x2
= 8
Hence, the dog food last for 8 days.

What is the slope and the y-intercept of a line whose equation is y=-4x-7
A. slope = -4; y-intercept = 7
B. slope = 4; y-intercept = -7
C. slope = -4; y-intercept = -7
D. slope = -7; y-intercept = -4
compare the equation with the formula y=mx+c and you will get the value of slope and the y intercept.
For example - y= 3x +4
On comparing y=mx+c
We will get m= 3 and
y intercept = 4
