Answer:

a>4

Step-by-step explanation:

work it just like you would if the > sign was an equal sign until you get to the last step

2a+4>12

subtract 4 from both sides

2a>8

divide both sides by 2

a>4  

thats your answer :)

What is the rate of change from x = pi x = 3pi/2
ipn [44]

Answer: 3/2 (simplified: 1.5)

Step-by-step explanation:

X=pi

X=3pi/2

Remove pi from both equations because pi will cancel out each other then you will be left with the equation 3/2. So therefore the rate of change would be 3/2 simplified would be 1.5

Angle B is 45% of angle A. Angle C is 35% of angle A. What is the measurement of angle A?
mafiozo [28]

We assume , A, B, and C are angles of a triangle.
The sum of angles of a triangle is equal to 180º; therefore:
A+B+C=180º

B is 45% of angle A; then B=0.45A
C is 35% of anble A; Then C=0.35A

We can suggest this equation;
A+0.45A+0.35A=180
1.8A=180
A=180/1.8
A=100

Answer: The measurement of angle A is 100º.

Find an equation of the line through (2,6) and parallel to y=2x+3
Setler [38]

Step-by-step explanation:

We first Find the Slope of the line y=2x+3

The Slope Intercept Form of the equation of a given line is:

y=mx+c

where m is the Slope of that line, and c is the Y intercept.

For this line, the Slope is 2

So the Slope of the line PARALLEL to y=2x+3 will also be 2. And we are given that it passes through the point (2,6)

The Point-Slope form of the Equation of a Straight Line is:

(y−k)=m⋅(x−h)

m is the Slope of the Line

(h,k) are the co-ordinates of any point on that Line.

Here, we have been given the coordinates (h,k) of 1 point on that line as (2,6)

And the Slope m is 2

Substituting the values of h,k and m in the Point-Slope form, we get

(y−2)=(2)⋅(x−6)

(y−2)=2⋅(x-6)

y−2=2x -12

y=2x -12 +2

y=2x-10

The graph will look like

graph{y=2x -10 10 [10, -10, 5, - 5]}
