Evaluate each
f(2)=2^2+1=4+1=5
g(1)=3(1)+1=3+1=4

[f(2)-g(1)]^2=(5-4)^2=1^2=1

answer is first one

Answer:

(d) 16

Step-by-step explanation:

Angles opposite sides of the same measure are congruent. Here, the triangle is isosceles, so the base angles are congruent:

2x = 32

x = 16 . . . . . . divide by 2°

Solve x - 5y = 6 for x. Ox= -5y + 6 Ox= -5y - 6 Ox = 5y + 6 Ox = 5y - 6

valentina_108 [34]

Answer:

See below

Step-by-step explanation:

Solve x-5y=6 for x

First, we need to isolate the x by moving -5y to the other side.

To do this, we need to add 5y to both sides

x - 5y= 6

+5y +5y

x= 5y+6

So, your third answer is correct

Determine if there is a proportional relationship between the two quantities

Shalnov [3]

Answer:

The table a not represent a proportional relationship between the two quantities

The table b represent a proportional relationship between the two quantities

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

Verify each table

Table a

Let

A ----> the independent variable or input value

B ----> the dependent variable or output value

the value of k will be

$k=\frac{B}{A}$

For A=35, B=92 ---> $k=\frac{92}{35}=2.63$

For A=23, B=80 ---> $k=\frac{80}{23}=3.48$

the values of k are different

therefore

There is no proportional relationship between the two quantities

Table b

Let

C ----> the independent variable or input value

D ----> the dependent variable or output value

the value of k will be

$k=\frac{D}{C}$

For C=20, D=8 ---> $k=\frac{8}{20}=0.40$

For C=12.5, D=5 ---> $k=\frac{5}{12.5}=0.40$

the values of k are equal

therefore

There is a proportional relationship between the two quantities

The linear equation is equal to

$D=0.40C$
