Mid segment = (1/2)base
12.5 = (1/2)* base
Multiply both sides by 2
25 = base
Letter b

An algebraic expression of the form a + bx has the value of 15 when x = 2 and the value of 3 when x = 5. Calculate a + b.
Ainat [17]

Answer:

The value of the expression  (a +b)  = 19

Step-by-step explanation:

The given expression is a + bx.

Case - I   when x = 2, (a + bx) = 15

Putting the value of x , we get:  a + 2b = 15

or, a = 15 - 2b       ......  (1)

CAse II-  when x = 5, (a + bx) = 3

Putting the value of x, we get a + 5b = 3

or a = 3 - 5b   ....... (2)

Comparing (1) and (2)

15 - 2b = 3 - 5b

or, 5b - 2b = 3 - 15

or, 3b = - 12   ⇒ b  = -4

if b = -4, then a = 3 - 5b = 3 + 20  = 23

Hence, a = 23, b= -4

So, the value of (a +b) = 23 - 4 = 19

The function with a rate of change of 4/5 that has a value of 10 at x=10
Aleks [24]

Answer:

y = \frac{4}{5} x + 2

Step-by-step explanation:

Assuming you require the equation of the function.

The slope m is a measure of the rate of change of the function.

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = \frac{4}{5} , thus

y = \frac{4}{5} x + c ← is the partial equation

To find c substitute (10, 10) into the partial equation

10 = 8 + c ⇒ c = 10 - 8

y = \frac{4}{5} x + 2 ← equation of function
