Answer:

when x=3, the answer is

f(3)=36

Step-by-step explanation:

You need to plug in 3 for x and then solve. :)

Hope this helps! If possible, could you please mark as brainliest? Thanks!

Answer:

Step-by-step explanation:

Wherever you put a 3 in for the x's that are on the right.

f(x) = 2x^2 - 3x + 9

f(3) = 2*3^2 - 3(3) + 9

f(3) = 2*9 - 9 + 9

f(3) = 18

What is the slope of the line represented by the equation 6y-14x=5

ioda

Answer:

slope = $\frac{7}{3}$

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y-intercept )

rearrange 6y - 14x = 5 into this form

add 14x to both sides

6y = 14x + 5 ( divide all terms by 6 )

y = $\frac{14}{6}$ x + $\frac{5}{6}$ ← in slope- intercept form

with slope m = $\frac{7}{3}$ ← in simplest form

The third angle in an isosceles triangle is 32 more than 2 times as large as each of the two base angles. Find the measure of ea

DIA [1.3K]

Answer: the third angle is 106 degrees.

The base angles are 37 degrees each.

Step-by-step explanation:

In an isosceles triangle, the base angles are equal.

Let x represent the measure of each of the base angles.

The third angle in an isosceles triangle is 32 more than 2 times as large as each of the two base angles. It means that the measure of the third angle would be

(2x + 32) degrees

The sum of the angles inna triangle is 180 degrees. It means that

x + x + 2x + 32 = 180

4x = 180 - 32

4x = 148

x = 37

The third angle is

2x = 32 = (2 × 37) + 32

= 74 + 32 = 106

Identify the value of m. Give your answers in simplest radical form. HELP PLEASE!!!

yan [13]

Answer:

m = 4√2

Step-by-step explanation:

This is a right angled isosceles triangle whose sides are in the ratio 1:1:√2.

So = 8 / √2

= 8 *√2 / 2

= 4√2
