F(-11/5) if f(n) = 5n + 6. f (-11/5) = 5 (-11/5) + 6 f (-11/5) = -11 + 6 f(-11/5) = -5 :)

6a=54 so a=54/6, a=9

b-a=14, and using a found above...

b-9=14

b=23, so a=9 and b=23 so

I’ll give brainliest

diamong [38]

Answer:

A=115.6

Step-by-step explanation:

Hey There!

So the first step is to find the formula for area of a trapezoid

$A = \frac{1}{2} h(b1 +b2)$

h = height

b1 = base 1

b2 = base 2

now all we do its plug in the values

$A=\frac{1}{2} 6.8(28.3+5.7)$

$6.8x26.3=192.44\\5.7x6.8=38.76\\38.76+192.44=231.2\\\frac{231.2}{2} =115.6\\A=115.6$

Hope this helps!!

Y= 3x-1 2x+6=y substitution method

vfiekz [6]

Answer: (7, 20)

Concept:

There are three general ways to solve systems of equations:

Elimination
Substitution
Graphing

Since the question has specific requirements, we are going to use substitution to solve the equations.

Solve:

Given equations

y = 3x - 1

2x + 6 = y

Substitute the y value since both equations has isolated [y]

2x + 6 = 3x - 1

Add 1 on both sides

2x + 6 + 1 = 3x - 1 + 1

2x + 7 = 3x

Subtract 2x on both sides

2x + 7 - 2x = 3x - 2x

$\boxed{x=7}$

Find the value of y

y = 3x - 1

y = 3(7) - 1

y = 21 - 1

$\boxed{y=20}$

Hope this helps!! :)
