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:
Step-by-step explanation:
So first we notice that the traingles are similar which makes my work much easier.
27:42 can be simplified to 9:14.
That means x is 28
And sharks to dolphins is 12.
That means the smaller triangle is 27 18 12 and the bigger triangle is 42 28 and x. Try and do it yourself if you can't just comment and I'll help you :)
To solve quadratics, the most correct and effective way, in my opinion, is the quadratic formula:

Answer:
82°
Step-by-step explanation:
m÷ BAD + m÷ BCD = 180°
98° + m÷BCD = 180°
m÷BCD = 180° - 98°= <u> </u><u>8</u><u>2</u>°
