Answer:
f(x) = 5x - 5
Step-by-step explanation:
Let the equation of the linear function is,
f(x) = mx + b
Here, m = Slope of the graph
b = y-intercept
Slope of the line passing through
and
is given by,
m = 
From the table attached,
Slope of the line passing through (2, 5) and (6, 25) will be,
m = 
m = 5
Equation of the linear function will be,
f(x) = 5x + b
Since, a point (10, 45) lies on the function,
45 = 5(10) + b
b = 45 - 50
b = -5
Equation of the linear function will be,
f(x) = 5x - 5
Answer:
-0.7
Step-by-step explanation:
● -9 + 8.3
Notice that 8.3 = 8 + 0.3
● -9 + (8 + 0.3)
● -9 + 8 + 0.3
-9 + 8 is -1
● (-9 + 8) + 0.3
● -1 + 0.3
-1 is (-0.3 -0.7)
● -0.3 - 0.7 +0.3
● -0.7
Answer:
x=1.26186
Step-by-step explanation:
There's an Algebra Calculator called Algebra Papa.
Answer:
4
Step-by-step explanation:
We subtract 3 from both sides to get rid of x and when we do so we get x = 7 - 3 = 4.
