Fine the line that is parellel toY= 2x +4 and passes through(-3,5)
Soloha48 [4]

To determine if a line is parallel to another, we need to find the slope of the given linear equation, since the parallel line is going to have the same slope.

The slope of a line m can be determined by first puting the linear equation into the slope-intercept form, which is

y = mx + b.

Given the equation as

y = 2x + 4, the slope is 2

However to solve for b, we can start by substituting for the values of y and x which are given as the coordinates of the point through which the line passes.

The given equation is;

\begin{gathered} y=mx+b \\ y=2x+b \\ \text{Substitute for the values of x and y} \\ 5=2(-3)+b \\ 5=-6+b \\ 11=b \\ \text{Having calculated b as 11, we now have the parallel equation as;} \\ y=2x+11 \end{gathered}

The line parallel to y = 2x + 4 is derived as

y = 2x + 11

Find the value of x. Round to the nearest tenth.
Aliun [14]

Answer:

Step-by-step explanation:

Triangle XYZ is a right angle triangle.

From the given right angle triangle

XZ represents the hypotenuse of the right angle triangle.

With ∠34 as the reference angle,

YZ represents the adjacent side of the right angle triangle.

XY represents the opposite side of the right angle triangle.

To determine x, we would apply the Cosine trigonometric ratio

Cos θ = opposite side/hypotenuse. Therefore,

Cos 34 = x/28

x = 28Cos34 = 28 × 0.8290

x = 23.212

To the nearest tenth, it becomes

23.2
