Step-by-step explanation:
Answer:
y=2 -7x-4
three linear equations
c=-4 ;4a+b=1 ; 9=a-b
Step-by-step explanation:
Simply assume a standard parabola equation y=a +bx +c
(here a, b, c are three independent variables)
Three coordinates as shown in graph are (0,4), (4,0) ,(-1,5)
Now put these points in the equation of parabola and get three linear equations.
[1] c=-4
[2] 4a+b=1
[3] 9=a-b
Now substitute value of a from equation 2 into 3 in terms of b
a=
9=-b
b=-7
a=2
y=2 -7x-4
Answer:
80 questions.
Step-by-step explanation:
-Let X be the number of problems solved on day 1.
-Questions solved on day 2 are:
We know that the total number of questions solved is 144:
Hence, the number of questions solved on the first day is 80
Answer:
24/35
Step-by-step explanation:
(2/7) + (2/5) =
(2*5)/(7*5) + (2*7)/(5*7) =
10/35 + 14/35 =
24/35
Here’s the answer and each step I took to solve it. With the example I made on the side just continue to repeat that for each one to get the answers. You just replace that one number for the X to take the place for the next X value as you go down the table solving them.
