Answer:
First question is B
Second question is also B :)
Step-by-step explanation:
The value of a=9,b=3 and c=1
Step-by-step explanation:
The graph shown is for function f(x)
The given function is f(x)=
Table says,
X Y
-2 a
1 b
0 c
1 (1/3)
2 (1/9)
To find value of a:
From table, for output value a, input value, x=(-2)
we can write f(-2)=a
Therefore,
f(x)=
f(-2)=
a=
a=
a=9
To find value of b:
From table, for output value a, input value, x=(-1)
we can write f(-1)=b
Therefore,
f(x)=
f(-1)=
b=
b=
b=3
To find value of c:
From table, for output value a, input value, x=(0)
we can write f(0)=c
Therefore,
f(x)=
f(0)=
c=
c=1
Answer:
y=-6x-57 is your answer.
Step-by-step explanation:
You will use this equation:
y-y1=m(x-x1). The y1 is -2 and the x1 is -9.
y-(-3)=-6(x-(-9)). You will the distribute the -6 into the x and the -9.
y+3=-6x-54. You will then subtract 3 to both sides.
y=-6x-57 is your answer.
Answer:
x=5
Step-by-step explanation:
You first have to distribute. So multiply the 3 with whats inside the parenthesis. So 3 times 2x is 6x. And 3 times -3 is -9. That means that so far you have 6x-9. Now on the other side you have 4x+1. So you move the 9 over to the other side by doing the opposite of it. Meaning +9. So you add 9 to 1 giving you 10. Now you have, 6x=4x+10. Just subtract 4x from 6x, which gives you 2x. Lastly, you divide the 10 by 2x because division is the opposite of multiplication
