Must m in the equation y=mx+b always be a positive number

2 answers:

7 0

Not at all.

'm' turns out to be the slope of the graph of the equation.

If the graph of the equation slopes upward as it goes
from left to right, then 'm' is positive.

If the graph of the equation slopes downward as it goes
from left to right, then 'm' is negative.

'm' is the slope.

The answer is no. There could be a negative number, which means that the slope would be decreasing, or as known as a negative slope (negative rate of change). <span />

Simplify. (-2xy4)^4

IrinaVladis [17]

Step-by-step explanation:

${( - 2x {y}^{4} })^{4}$

$= {( - 2)}^{4} \times {x}^{4} \times { {y}^{4} }^{4}$

$= 16 {x}^{4} {y}^{16}$

Reil [10]

Answer:

13.36

Step-by-step explanation:

I will first create a table

X. Y. XY. X²

1. 20. 20. 1

2. 24. 48. 4

3. 35. 105. 9

4. 46. 184. 16

5. 67. 335. 25

6. 80. 480. 36

1. 12. 12. 1

2. 34. 68. 4

3. 34. 102. 9

5. 78. 430. 25

ΣX = 32

ΣY = 430

ΣXY = 1744

ΣX² = 130

n = 10

The formula for regression line is given as :

Y = a + bX

a = intercept

b = slope

The question requires us to find b which is the slope.

b = nΣXY-ΣXΣY/nΣX²-(ΣX)²

= 10x1744-32x430/10x130-(32)²

= 17440-13760/1300-1024

= 3680/276

= 13.36

b = 13.36

Some please help and explain the steps. Tysmmmmm

-Dominant- [34]

Answer:

since angle B and angle C contains the same arc AD. set the angles equal

11x-3=8x+15

x=6

so the angle has a measure of 63 degrees

the central angle is the angle of the arc

and it is always 2 times the angle that we just that contains the arc but does touches the end of the circle.

so its 63 *2 =126 degrees.
