write an expression for the calculation the difference of 35 and 7 divided by the difference of 9 and 2

What is the slope of the table x= 2, 0, -2, -4 y= 6, 1, -4, -9

Murrr4er [49]

Answer:

The slope of the table is $m=\frac{5}{2}$ or $m=2.5$

Step-by-step explanation:

we know that

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have the following ordered pairs

(2,6),(0,1),(-2,-4) and (-4,-9)

take two points

(2,6) and (-4,-9)

substitute in the formula

$m=\frac{-9-6}{-4-2}$

$m=\frac{-15}{-6}$

simplify

$m=\frac{5}{2}$

Hi!! Please help me with this question. I got an answer of 63.25 but it was incorrect and need to redo it. Please also explain h

matrenka [14]

Answer:

x ≈ 63.27

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan49° = $\frac{opposite}{adjacent}$ = $\frac{EF}{DE}$ = $\frac{x}{55}$ ( multiply both sides by 55 )

55 × tan49° = x , then

x ≈ 63.27 ( to the nearest hundredth )

Why do you multiply by a power of 10 when writing a repeating decimal as a rational number

stira [4]

1.28 = 128 * 10^-2

128 * (1/10^2)

128 / 10^2

128 / 100

1.28

Because, it's literally the same thing mathematically if you worked it out. Though, as I'm sure you're aware, it's just a much shorter and cleaner way of writing out large or small numbers.

Line a passes through the points (-1,0) and (3,-8) what’s the slope?

konstantin123 [22]

Answer: 2

Step-by-step explanation:

(x1,y1) = (-1,0)

(x2,y2) = (3,8)

m = (8–0)/(3-(-1))

m = 8/(3+1)

m = 8/4

m = 2
