Answer:

x = 40

y = 15

Step-by-step explanation:

Given is an equilateral triangle.

Measure of each angle of an equilateral triangle is 60°.

Therefore,

(x + 20)° = 60°

x + 20 = 60

x = 60 - 20

x = 40

4y = 60

y = 60/4

y = 15

D, just got it righ,t May 2021

Step-by-step explanation:

x ≤ 3 or x ≥ -1 represent the given graph.

Option (4) is correct.

Inequalities are mathematical formulas in which neither side is equal. Unlike equations, we compare two values in inequality.

As per the given diagram:

A line is drawn and a certain range of values are marked on the line,

To find the compound inequality that could be represented by the graph.

Because a number line with only real numbers is displayed in the provided graph.

We identify the solution set for each option by considering it separately.

1) -4 ≤ x ≤ 4

Since, the solution set contain only numbers between -4 and 4.

So it is false.

2) -2 ≤ x ≤ -1

This is a wrong representation.

3) x ≤ -1 or x ≥ 0

This represents all real numbers, excluding numbers between -1 and 0

So it is false.

4) x ≤ 3 or x ≥ -1

So it represents all the real numbers on number lines as shown in the graph below.

So, it is true.

x ≤ 3 or x ≥ -1 represent the given graph.

Answer:

This is a binomial situation.

Step-by-step explanation:

For each attempt, there are only two possible outcomes. Either you catch a fish, or you do not. This can mean that either we have a binomial distribution, or a geometric.

However, each attempt is independent, which means that in each attempt, the probability of catching a fish is the same, and that this is a binomial situation.

The probability of catching a fish on each cast of my rod is a binomial distribution.

Hence the probability of catching a fish on each cast of my rod is a binomial distribution.

Answer:

x=−2 and y=−5

Step-by-step explanation:

Solve3x−2y=4for x:

3x−2y=4

3x−2y+2y=4+2y(Add 2y to both sides)

3x=2y+4

3x /3 = 2y+4 /3 (Divide both sides by 3)

x= 2 /3 y+ 4 /3

Substitute  2 /3 y+ 4 /3 for x in6x−2y=−2:

6x−2y=−2

6( 2 /3 y+ 4 /3 )−2y=−2

2y+8=−2(Simplify both sides of the equation)

2y+8+−8=−2+−8(Add -8 to both sides)

2y=−10

2y /2 = −10 /2 (Divide both sides by 2)

y=−5

Substitute−5 for y in x=

2 /3 y+ 4 /3 :

x= 2 /3 y+ 4 /3

x= 2 /3 (−5)+ 4 /3

x=−2(Simplify both sides of the equation)

Answer:

  -12, -21

Step-by-step explanation:

Let x represent the first number. Then the second is x-9. The other relation is ...

  4x = 2(x-9) -6

  2x = -24 . . . . . subtract 2x, simplify

  x = -12

  x-9 = -21

The first number is -12; the second number is -21.

Simplifying

P + -21 + -21 = 34 + -21  

-21 + -21 + P = 34 + -21

Combine like terms: -21 + -21 = -42

-42 + P = 34 + -21

Combine like terms: 34 + -21 = 13

-42 + P = 13

Solving

-42 + P = 13

Solving for variable 'P'.

Move all terms containing P to the left, all other terms to the right.

Add '42' to each side of the equation.

-42 + 42 + P = 13 + 42

Combine like terms: -42 + 42 = 0

0 + P = 13 + 42

P = 13 + 42

Combine like terms: 13 + 42 = 55

P = 55

Simplifying

P = 55
