Find the value of x. Round your answer to the nearest tenth.
Stels [109]

Answer:

9.30

Step-by-step explanation:

Using SOHCAHTOA

tan=opposite/adjacent

tan25°=x/20

tan 25°=0.4663

0.4663=x/20

cross multiply

x=0.4663*20

x=9.326

to the nearest tenth=9.30

Find an equation of the line through (3,5) and parallel to y = 3x -7. Write the equation using function notation
ki77a [65]

Given:

Equation of line is y=3x-7.

To find:

The equation of line which is parallel line to y=3x-7 and passes through (3,5) in function notation.

Solution:

Slope intercept form of a line is

y=mx+b

where, m is slope and b is y-intercept.

On comparing the equation y=3x-7 with slope intercept form, we get

m=3

So, slope of given line is 3.

Slope of parallel lines are same. Thus, the slope of parallel line is also 3.

Point slope form of a line is

y-y_1=m(x-x_1)

where, m is slope.

The parallel line passes through (3,5) with slope 3. So, the equation of line is

y-5=3(x-3)

y-5=3x-9

Add 5 on both sides.

y=3x-9+5

y=3x-4

Function notation of this equation is

f(x)=3x-4

Therefore, the equation equation in function notation is f(x)=3x-4.

What is the solution to 2x-6y=2<br> -4x+8y=-8
-BARSIC- [3]

Answer:

Step-by-step explanation:

2x-6y=2 ....(1)

-4x+8y=-8....(2)

divid the equation (2) by : - 2 x +4y = - 4...(3)

add (1) and (3 ) :2x-6y - 2 x +4y =2-4

-2y=-2

y = 1

put y=1 in (1) : 2x-6(1)=2

2x=8

x =4
