Solve each equation using substitution. Answers are on the right and questions are on the left.

Answers

Answer:

Q1. No solutionQ2. (5, 6)Q3. Infinitely many solutionsQ4. No solutionQ5. (2, 3)

Step-by-step explanation:

Q1.

y = -1/3x - 1x + 3y = -12

Solution

x + 3(-1/3x - 1) = -12x - x - 3 = -12-3 = -12

No solution

y = 2x - 4y = x + 1

Solution

2x - 4 = x + 1x = 5y = 6

(5, 6)

y = -3x + 36x + 2y = 6

Solution

6x + 2(-3x + 3) = 66x - 6x + 6 = 66 = 6

Infinitely many solutions

- 5x + y = 1- 10x + 2y = -2 ⇒ -5x + y = -1

Solution

1 = -1

No solution

y = 1/2x + 2y = x + 1

Solution

1/2x + 2 = x + 11/2x = 1x = 2y = 3

(2, 3)

Which is equivalent to 42x +49.

A. 2 (21 + 24)

B. 8x + 13

C. 4 (2x + 9)

D. 7 (6x + 7

Answers

Answer:

D. 7 (6x+7)

Step-by-step explanation:

Factor 7 out of 42x + 49

The answer is
D. 7(6x+7)

9y-7=29
Prove y=4
Solve the problem

Answers

9y - 7 = 29

=> 9y = 29 + 7 [Transferring 7 to R.H.S.]

=> 9y = 36

=> y = 36/9 [Transferring 9 to R.H.S.]

=> y = 4

Hence proved.

the question: “which trig. ratio woild you use to find the missing side?”

Answers

Answer:

Step-by-step explanation:

It's not the tangent. The tangent relates two sides neither of which is the hypotenuse, which you are given.

The trig ratio you would use is the one that relates the angle to the side opposite the angle and the hypotenuse.

That is the definition for the Sine.

first use the point slop formula
y-y1=m(x-x1)

with your points it would give you the equation
y+3=-3/5(x+5)

then solve it so that it becomes in the form y=mx+b

in your case your answer would be y=-3/5x + 0

An object is moving east, and it’s velocity changes from 65 m/s to 25 m/s in 10 seconds.which describes acceleration

Answers

Answer:

The acceleration of object is -4 ms⁻²

Step-by-step explanation:

We are given:

Initial Velocity = 65 m/s

Final Velocity = 25 m/s

Time t = 10 seconds

We need to find acceleration.

The formula used to find acceleration is: [tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}[/tex]

Putting value in the formula and finding acceleration:

[tex]Acceleration=\frac{Final\:Velocity-Initial\:Velocity}{Time}\\Acceleration=\frac{25-65}{10}\\Acceleration=\frac{-40}{10}\\Acceleration=-4\:ms^{-2}[/tex]

So, acceleration of object is -4 ms⁻²
