Could someone answer these 3 for me?
KengaRu [80]

Answer:

x=4.77

Angle 3=98.32 degrees

Angle 6= 81.68 degrees

Step-by-step explanation:

(Assuming these are parallel lines), Angle 3 and angle 5 are equal because they are alternate Angles. Therefore we can write the following equation to solves for x:

16x+22=3x+84 (angle 3=angle5)

Which we can now solve:

16x +22 - 22 - 3x=3x-3x+84-22

13x=62

13x/13=62/13

x=4.77 (2dp)

We can then use this x to calculate angle 3:

16(4.77)+22

76.33+22=98.32 degrees

Finally,

Angle 6 and angle 3 are interior angles, so they add up to 180 degrees.

So to find angle 6,we can just subtract angle 3 from 180:

180-98.32=81.68 degrees.

Hope this helped!

What is f(3) for the quadratic function<br>f(x)=2x2 + x – 12?<br>F -3<br>G 3<br>H 6<br>I. 9​
PolarNik [594]

Answer:

f(3) = 9

Step-by-step explanation:

Wherever you see an x on the right, put a 3 in for that x

f(x) = 2x^2 + x - 12

f(3) = 2*(3)^2 + 3 - 12

f(3) = 2*9 + 3 - 12

f(3) = 18 + 3 - 12

f(3) = 9

Kini and Duke are each working during the summer to earn money in addition to their weekly allowance, and they are saving all of
postnew [5]

Answer:

6hrs

Step-by-step explanation:

First, we have to put the information given to us about the money they earn into an expression

let x represent the number of hours Kini and Duke work and y represent the total amount of money they earn in a week.

y(kini) = 9x + 8

y(duke) = 7.5x + 17

Now we subtract the x values and the constant values

9x - 7.5x = 1.5x

17 - 8 = 9

Make these into an equation

1.5x = 9

Divide both sides by 1.5 so x(the number of hours the both work) can stand alone.

\frac{1.5x}{1.5}= \frac{9}{1.5}

x = 6 hrs
