Answer:

Part A) The equation of the line m is x=3

Part B) The equation of the line n is y=-4

Step-by-step explanation:

Part A) Line m has no y-intercept, and its x-intercept is (3, 0)

we know that

If a line has no y-intercept , then is a vertical line (parallel to the y-axis)

the equation of the line m is equal to the x-coordinate of the x-intercept

so

x=3

Part B) Line n has no x-intercept, and its y-intercept is (0, -4)

we know that

If a line has no x-intercept , then is a horizontal line (parallel to the x-axis)

the equation of the line n is equal to the y-coordinate of the y-intercept

so

y=-4

The interior angle measures of a convex pentagon are consecutive multiples of 4. find the measure of each interior angle.
lawyer [7]

Answer:

100°, 104°, 108°, 112°,116°

Step-by-step explanation:

Let the smallest angle be 4x. Since, the interior angles are consecutive, the other angles are 4(x+1),4(x+2),4(x+3) and 4(x+4).

Sum of interior angles = 540°

4x+4(x+1)+4(x+2)+4(x+3)+4(x+4)=540°

20x+40=540°

20x=(540-40)°

20x=500°

x=(500/20)°

x=25

Using the value of x to calculate the angles:

4x=4*25=100°

4(x+1)=4*26=104°

4(x+2)=4*27=108°

4(x+3)=4*28=112°

4(x+4)=4*29=116°

Is x^ 2 - 16 the difference between two squares? Why?
bearhunter [10]

Answer:

x1= -4

x2 = 4

Step-by-step explanation:

Set the equation equal to zero

x2 − 16 = 0

then

(x + 4)(x − 4) = 0

(x+4)= 0 which is equal to -4

and

(x-4)= 0 equals 4

Given the formula y = -1/2x - 4, what is the slope and y-intercept of the graph? PLEASE HELP!​
svet-max [94.6K]

Answer:

the slope is -1/2 and the y-intercept is -4

Step-by-step explanation:

The original formula is y=mx+b. m is the slope of the graph and b is the y-intercept. You just plug in the numbers to the original formula to get the formula for the graph. The slope is always the number that is right next to the x, or the number which is multiplied by the x. The y-intercept is always the number that is not by x.

muminat

Answer:

slope = -1/12

Step-by-step explanation:

From the figure we can see that the line passes through 2 points which are

(-6,-1) and (6,-2)

Use the formula y2-y1/x2-x1

(-2-(-1))/6-(-6)

(-2+1)/6+6

-1/12
