Step-by-step explanation:

= f (8) - f (-5)

= 3*8-2 -(3*-5-2)

= 22-(-15-2)

= 22+17

= 39

F(8)=3(8)-2=22
f(-5)=3(-5)-2=-17

f(8)-f(-5)
=22-(-17)
=22+17
=39

Blain is two years older than three times Jillians age. Jillian is also 16 years younger than Blain. How old is Blain?
Ipatiy [6.2K]

The age of Blain is 23 years old

<h3><u>Solution:</u></h3>

Let the age of Blain be "a" and age of Jillian be "b"

Given that Blain is two years older than three times Jillians age

So we can frame a equation as:

age of blain = 2 + 3(age of Jillian)

a = 2 + 3b ----- eqn 1

Also given that Jillian is also 16 years younger than Blain

Age of Jillain = Age of Blain - 16

b = a - 16 ---- eqn 2

Substitute eqn 2 in eqn 1

a = 2 + 3(a - 16)

a = 2 + 3a - 48

a - 3a = -46

-2a = -46

a = 23

Thus the age of Blain is 23 years old

Use the pencil,plot the point (3 1/2, 2 3/4)
kipiarov [429]

Answer:

The diagram of the plotting point \left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right) is attached below.

Step-by-step explanation:

Given the points

\left(3\frac{1}{2},\:2\frac{3}{4}\right)

as

3\frac{1}{2}=\frac{7}{2}=3.5

2\frac{3}{4}=\frac{11}{4}=2.75

so the point can be visualized as:

\left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right)

Now, we can check the point x = 3.5, and determine the corresponding value y = 2.75 and plot the point at the location (x, y) = (3.5, 2.75)

The diagram of the plotting point \left(3\frac{1}{2},\:2\frac{3}{4}\right)=\left(3.5,\:2.75\right) is attached below.

a student found the slope of a line that passes through the points (1,14) and (3,4) to be 5. what mistake did she make?
mariarad [96]
x_{1}=1
x_{2}= 3
y_{1} =14
y_{2}=4
Slope= \frac{rise}{run} = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1} } = \frac{4-14}{3-1} = \frac{-10}{2} =-5


answer: The student flipped the y values
