Remember the PEMDAS

Parenthesis and exponents

Multiplication and division

Addition and subtraction
Here is the first problem


2+6*3^2

You would start with the 3^2 and that is basically 3*3=9

2+6*9

then you would do the 6*9=54

2+54

then you would simply add them and you would get 56

A.56


Second problem

3*4^2-2*6

This one looks complicated but its just as easy as the first problem.

4^2 is like 4*4=16

3*16-2*6

so the next step would to be multiply the 3*16=48

48-2*6

then you would multiply the 2*6=12

48-12=36

B. 36



Hope this helps you!

Just use the order of operations. PEMDAS, parentheses, exponents, multiplication, division, addition and subtraction.

In the first problem 2 + 6*3^2, there are no parentheses, so next would be exponents.
There is an exponent so you do that first.
3^2 = 9

Now we have 2 + 6*9
Multiplication is next and it is in the problem, so we do 6*9 = 54
So now we have 2 + 54 which equals 56.

Write the equation of the line perpendicular to 2x+3y=9 that passes through (-2,5). Write your answer in slope-intercept form. S
amid [387]

Answer:

y = (3/2)x + 8

Step-by-step explanation:

Hi

First let's find the slope of the given line by converting to slope-intercept form:-

2x + 3y = 9

3y = -2x + 9

y = (-2/3)x + 3

From this we see that the slope is -2/3.

The slope of a line perpendicular to this one will be - 1 /  (-2/3)

= 3/2.    ( because for a line and its perpendicular, the slopes' product = -1).

Using the point-slope form  to find the equation of this line

y - y1 = m(x - x1).  Here m = slope and (x1, y1) is a point on the line.

Plugging in the given values ,  m = 3/2 , x1 = -2 and y1 = 5:-

y - 5 = 3/2 (x - -2)

y - 5 = 3/2x + 3

y = (3/2)x + 8   which is the equation in slope-intercept form.

For f(x)= 4x+1 and g(x) = x squared -5 , find (f-g)(x)
makvit [3.9K]
Hope i am not wrong
f(x)=4x+1
g(x)=x^2-5

(f-g)(x)=f(x)-g(x)
(f-g)(x) =4x+1-x^2+5

-(x^2-6-4x)
solve it for x
