Answer:

Step-by-step explanation:

g(x) = 3x + 5

g(3) = 3(3) + 5

g(3) = 9 + 5

g(3) = 14

-----------------------

f(x) = 2x² + 3

f(g(3)) = 2(g(3)) + 3

f(14) = 2(14²) + 3

f(14) = 2(196) + 3

f(14) = 392 + 3

f(14) = 395

-----------------------------

f(g(3)) = 395

I need help ASAP with this question

$\frac{7}{10} =\frac{7*4}{10*4}=\frac{28}{40}$

$\frac{3}{4} =\frac{3*10}{4*10} =\frac{30}{40}$

As you can see:

$\frac{28}{40}$

$\frac{7}{10}$

An isosceles triangle has two sides of equal length. The third side is five less than twice the length of one of the other sides

4vir4ik [10]

Answer:

Step-by-step explanation:

We can set up a systems of equations to find the value of the third side.

Let's assume that $x$ is the length of both sides 1 and 2. Let's also assume that $y$ is the length of the third side.

We know that $x + x + y = 23$ , and looking at the first clue we can make the equation $y = 2x-5$ .

We can substitute y into the equation $x + x + y = 23$ .

$x + x + (2x-5) = 23\\\\2x + 2x-5 = 23\\4x-5 = 23\\4x = 28\\x = 7$

So the length of the side that is the same as the second is 7.

Now we can plug this into the equation $y = 2x-5$ to find $y$ .

$y = 2(7) - 5\\\\y = 14-5\\\\y = 9$

Hope this helped!

Determine if the following pairs of lines are parallel, perpendicular, or neither (HINT: Look at slopes).

GarryVolchara [31]

Answer:

Neither

Step-by-step explanation:

The slopes are not opposite and they are not equal either

line up 2x+3y=42 and -3x +2y=16

2x+3y=42=-3x+2y=16

get each term on one side and isolate.

If this is not possible, you have your answer. Another way to do this is graphing it and seeing if the two lines intersect, and if they do, if they make a right angle
