Answers

Answer:

(4 1/3, 1/9)

Step-by-step explanation:

Given system

4x + 6y = 18(y + 2) = 1/3(x + 2)

Solution is the intersection point:

(4 1/3, 1/9)

Simplify the first equation:

2x + 3y = 93y = -2x + 9y = -2/3x + 3

Check:

1/9 = -2/3*4 1/3 + 91/9 = -26/9 + 91/9 = (27 - 26)/91/9 = 1/9

Simplify the second equation:

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

Answers

Answer:

y = -2/3x - 1

Step-by-step explanation:

First, find the slope so you can see that when x goes up by 3, y goes down by 2. This means that the slope is -2 divided by 3, or -2/3.

You can see in the picture that the y-intercept is at the point (0, -1).

That means the equation would be y = -2/3x - 1

Answers

Answer:

D

Step-by-step explanation:

Answer: D

The inequality k > 9 / 2 is represented by graph D.

What is inequality?

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than relationship between variables and the numbers.

Given that the inequality is k > 9 / 2. The inequality is represented as the value of k is greater than the value 9 / 2 or 4.5. On the graph, the inequality will cover the region that is greater than the value of 4.5.

The graph of the inequality is attached with the answer below.

In ΔXYZ, the measure of ∠Z=90°, the measure of ∠X=57°, and XY = 8 feet. Find the length of YZ to the nearest tenth of a foo

Answers

Answer:

9.5 feet

Step-by-step explanation:

We solve this question using Sine rule

XY/sin X = YZ/Sin Z

From the question:

∠Z=90°

∠X=57°

XY = 8 feet.

8/sin 57 = YZ/sin 90

Cross Multiply

sin 57 × YZ = 8 × sin 90

YZ = 8 × sin 90/sin 57

YZ = 9.53891 feet

Approximately = 9.5 feet

Therefore, the length of YZ is 9.5 feet

Jelani has twice as much money on his subway pass as Alexis. If they both add $20 to their passes, Jelani will have 1.5 times as much on his pass as Alexis. Write an equation to represent this situation.

Answers

Answer:

since J=2A

2A+20=1.5(A+20)

Step-by-step explanation:

J=2A

2A+20=1.5(A+20)

simplified for proof

J+20=1.5A+30

.5A=10

A=20

J=40

Equation for situation is x - 1.5y = 10, where x is the money of Jelani and y is money of Alexis.

What are linear equations?

An algebraic equation with a variable with a highest exponent of one is known as a linear equation. Some linear systems have three equations, but not all linear equations have one, two, or three variables. Generally, an arrangement of straight condition has just a solitary arrangement yet at times, it has no arrangement or boundless number of arrangements.

Given Jelani has twice the money as Alexis,

let Jelani have money be x and Alexis have money be y

according to question x = 2y

and if both add  $20 dollar to their pass Jelani will have 1.5 times much than Alexis, so x + 20 = 1.5(y + 20)

simplify x - 1.5y = 10

Hence the equation will be x - 1.5y = 10
