Which of the following linear equations has the steepest slope
Pani-rosa [81]

Option B: 8x+1 has the steepest slope

Step-by-step explanation:

Slope is defined as the rate of change of a line

The steepness of a slope means how close it is to being vertical

The greater value of slope means, more steepness. The value of slope can wither b positive or negative

We have to compare the slopes of all given options to find the steepest slope

As the options are in slope-intercept form, the coefficients of x will be the slope

So,

a. Slope = -4

b. Slope = 8

c. Slope = 2/3 = 0.66

d . Slope = 1/7 = 0.14

We can see that the largest value of slope in negative and positive is 8

So,

Option B: 8x+1 has the steepest slope

Keywords: Slope, steepness

The polygon in the diagram is a regular octagon with center A. Find the area of the octagon to the nearest tenth of a foot. A) 2
IRISSAK [1]
Method 1: In order to find out the area of an octagon with a radius of 4 feet, we have to split the whole figure into 8 equal isosceles triangles.
Therefore, 
We will find out the area of one triangle and multiply the area with 8 to, figure out the area of the whole octagon there are 8 similar triangles and all of them will have the same area.

Method 2: From method 1, it would take time as there are too much of calculation, therefore we would go for the shortcut using the formula:

Area = 2√2 × r²

where r<span> is the radius of the octagon.
Substituting the values,
We get:
             </span>Area = 2√2 × 4²
             Area = 2√2 × 16
             Area = 2× 1.41 × 16 
             Area = 2.828 × 16 
            Area = 45.25

Rounded to the nearest tenth:

Area = 45.3 ft²

Find the value of x in the parallelogram below.
alina1380 [7]

Answer:

102

Step-by-step explanation:

78 and x are adjacent angles.

Sum of adjacent angles is 180 in a parallelogram.

78 + x = 180

x = 180 - 78

x = 102
