Answer:

Step-by-step explanation:

question 1.   13) 1/2 ( 4a + 12) =

(13(1/2) ) (4a) + (13(1/2) ) (12) = 26a+78

question 2.    (14)(4)b2+3.5−2a+3.5b2−a

=56b2+3.5+−2a+3.5b2+−a

Combine Like Terms:

=56b2+3.5+−2a+3.5b2+−a

=(56b2+3.5b2)+(−2a+−a)+(3.5)

=59.5b2+−3a+3.5

What is an example of a square root function? In (,) form
RUDIKE [14]

Step-by-step explanation:

The parent function of the functions of the form f(x)=√x−a+b is f(x)=√x . Note that the domain of f(x)=√x is x≥0 and the range is y≥0 . The graph of f(x)=√x−a+b can be obtained by translating the graph of f(x)=√x to a units to the right and then b units up.

Isosceles triangle = 2 sides equal.

Equilateral triangle = All sides equal.

Right angled triangle = One angle is 90.

Since, the picture hasn't given any sides, i am gonna say it's a scalene triangle.

If, the triangle is for measure, measure it using a ruler and classify it based on the result.

Solve the system using elimination<br> 3x+y=27<br> -3x+4y=-42
padilas [110]

Hello :)

3x+y=27

-3x+4y= -42

+____________

(3x -3x) + (y+4y) = (27-42)

0 + 5y = -15

y = -3

Put "-3" for "y" in the system:

3x + y =27

3x -3=27

3x = 30

x = 10

Answer = x:10 y: -3

Have a nice day :)
