there is a certain number. If you add 30 7 to it, then subtract 22 7 from the previous result, and then subtract that difference from 59/7, after that you will get 19 7. What is a certain number?

Answers

Step-by-step explanation:

59 / 7 - ( x + 30 / 7 - 22 / 7 ) = 19 / 7

59 / 7 - ( x + 8 / 7 ) = 19 / 7

59 / 7 - x - 8 / 7 = 19 / 7

- x = 19 / 7 - 59 / 7 + 8 / 7

- x = - 32 / 7

x = 32 / 7

find the slope of the line if it exists
a. the slope is ___
b. the slope is undefined

Answers

Answer:

The slope is -4/3.

Step-by-step explanation:

Slope = rise/run. Starting at (3, -1), you go up 4 units and over to the left 3 units to (0,3). Since it's a line of decay, the slope is negative.

Answer:

the slope should be -4/3

Step-by-step explanation:

you go down 4 and to the right 3 so I am pretty sure it is -4/3

General Formulas and Concepts:

Pre-Alg

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define equation

-17 = -3/2b

Step 2: Solve for b

Rewrite:                                       -3/2b = -17Divide both sides by -3/2:          b = 34/3

Step 3: Check

Plug in b to verify it's a solution.

Answer:

1. 2

2.circle

3.b tan t

Step-by-step explanation:

The slope of the equations x = 1 + 3t and y = -1 + 6t is 6, the equations x = 5 cos t and y = 5 sin t describe a circle and if x = a sec t is one of the parametric equations, the other will be y =b tan t

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The equation x = 1 + 3t and y = -1 + 6t can be expressed in the form y = mx + b, where m is the slope and b is the y-intercept.

In this case, m = 6, which is the slope of the line.

The equations x = 5 cos t and y = 5 sin t describe a circle.

These equations define the parametric form of a circle with a radius of 5 centered at the origin.

if x = a sec t is one of the parametric equations, the other will be y =b tan t

Hence, the slope of the equations x = 1 + 3t and y = -1 + 6t is 6, the equations x = 5 cos t and y = 5 sin t describe a circle and if x = a sec t is one of the parametric equations, the other will be y =b tan t

Subtract 5x^2+8x-11 from 3x^2+8x-7

Answers

Answer: -2x^2+4

Explanation: First you’d need to rewrite the equation as (3x^2+8x-7)-(5x^2+8x-11). Then since you are subtracting, distribute the negative to the right side which will then give you -5x^2-8x+11 since you flip the signs. Then simply combined like terms. -5x^2 + 3x^2 is -2x^2. Then 8x-8x is 0 and lastly, +11-7 is 4. So in order, all together, your answer is -2x^2+4.
