Answer:

m [ slope ] = 8/3

Step-by-step explanation:

What is the slope of the line that passes through the points (5, 1) and (2, -7)?

m = ∆y / ∆x

m = y₂ – y₁ / x₂ – x₁

| (5, 1) → (x₁, y₁) | (2, -7) → (x₂, y₂) |

[each coordinate will correspond (directly go to) to the variables shown]

m = (-7) – (1) / (2) – (5)

m = -8 / -3

m = 8 / 3

This means that this line has a rise of 8 and a run of 3.

Up 8 and right 3 proportionally, it would touch the opposite corners of a plane that was 8 by 3 units.

Slope can be thought of as the steepness of a line, the greater the slope, the greater the steepness.

These points are generally known as cartesian coordinates.

____________

Once you have the slope, you can back track from one of the coordinates to find the equation of the line.

Just multiply the slope by the x of either coordinate, make it opposite, and then add that to the y of that coordinate to get b [the y-intercept; where it crosses the y axis, x is always 0]

Since (2, -7) is closer to the y axis than (5, 1) it is more convenient.

In (2, -7), 2 is the x variable and -7 is the y variable.

-mx + y = (-8/3)(2) + (-7) = -16/3 + (-21/3)

21/3 is the same as 7 [so it will have a common denominator].

-16 + -21 / 3 = -37/3 = b

Thus this line has an equation of

y = mx + b

↓ ↓

y = 8/3x – 37/3.

__________________________

Or you can refer to point slope which is what is taught:

y – y₁ = m(x – x₁).

You can tell that there are some similarities to this and the slope formula.

m = ( y₂ – y₁ / x₂ – x₁ ) →

m × ( x₂ – x₁ ) =

( y₂ – y₁ / x₂ – x₁ ) × ( x₂ – x₁ )

[multiply the denominator by both sides]

m ( x₂ – x₁ ) = y₂ – y₁

[x₂, and y₂ can just be x and y since you only need the initial coordinate and slope, because the second coordinate can be anything along that line]

m ( x – x₁ ) = y – y₁ →

y – y₁ = m(x – x₁)

[symmetric property of equality]

if a = b, b = a.

The answer is 64

Step-by-step explanation:

Answer:

64

Step-by-step explanation:

12 + (8 x (4 + 3) + 2) - 6

= 12 + ( 8 x 7 + 2 ) - 6

= 12 + ( 56 + 2 ) - 6

= 12 + 58 - 6

= 70 - 6

= 64

Answer:

f(x)=-2x^2+32x-114

Step-by-step explanation:

Answer:

f(x) = -2x^2 + 142

Step-by-step explanation:

f(x) = -2(x - 8)^2 + 14

f(x) = -2(x)^2 - (-2)(-8)^2 + 14

f(x) = -2x^2 - (-2)(64) + 14

f(x) = -2x^2 - (-128) + 14

f(x) = -2x^2 + 128 + 14

f(x) = -2x^2 + 142

Answer:

Option C. Side a 1.5 inches long, side b is 2 inches long and side c is 2.5 inches long

Step-by-step explanation:

The scale factor=4:1=4/1

Scale factor=(Scale drawing)/object

4/1=6/a

4a=6

a=6/4

A=1.5 inches

4/1=8/b

4b=8

b=8/4

B= 2 inches

4/1=10/c

4c=10

c=10/4

C=2.5 inches

Therefore, side a is 1.5 inches long and side b is 2 inchea long and side c is 2.5 inches long

Answer:

C

Step-by-step explanation:

with the scale factor being 4:1 (meaning shape A is bigger then shape B by 4 times) we can divide the larger shapes dimensions by 4 to get ur answer

Answer:

i hope this helps :)

The value of the inequality will be : y ≥ -10 .

Given ,

y-5 ≥ -15

Here,

y-5 ≥ -15

To solve the given inequality,

Take -5 from LHS to RHS of inequality,

y ≥ -15 + 5
y≥ -10

Thus the value of y will be equal to or greater than -10 .

Answer: I think it is x= 3/74

Step-by-step explanation:

Answer:

x=3/74

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

20/3x=1/2x+1/4

Step 2: Subtract 1/2x from both sides.

20/3x-1/2x=1/2x+1/4-1/2x

37/6x=1/4

Step 3: Multiply both sides by 6/37.

(6/37)*(37/6x)=(6/37)*(1/4)

x=3/74

Thus, your answer will be x=3/74.
