Answer:

Option b) is correct

3x+4(2x+4)=17 Substitute (2x+4) for y in the second equation

Step-by-step explanation:

Given Equations are

$y=2x+4\hfill (1)$ and $3x+4y=17\hfill (2)$

To solve the given equations we have to find the value of

x and y values.

Here y value is given so that we can substitute y=3x+4 value in second equation

ie., Substitute equation (1) in (2) equation we can easily get x value.

Therefore substitute (2x+4) for y in the second equation we get

3x+4(2x+4)=17

Option b) is correct

7. What is the arc length shown in the picture? Leave your answer in terms of pi.

snow_lady [41]

Answer:

$14\pi$

Step-by-step explanation:

Arc length = $2\pi r(\frac{x}{360} )$ where x is the angle

∴ For this question, the arc length is:

Arc length $= 2\pi (8)(\frac{315}{360})$

Arc length = $14\pi$
