How do I find the domain and range of a graph?​

Answers

The domain is the x-axis and the range is the y-axis.

To find the domain, you measure or count the widest part of this oval horizontally. So that is 3 units to the right of 0 and 3 units to the left of 0. I counted it exactly on the axis because that is the widest part of the oval.

To find the range, you again count or measure the widest part of the oval vertically. So that is 4 units above 0 and 4 units below 0.

what is the answer to -3x+5= -16

Answers

Answer: 7

Step-by-step explanation: First you subtract 5 from both sides to single out the -3x. Then you will have -3x = -21. You will then divide both sides by negative three because you want to single out the x. After that, you will have the answer of x = 7

Answer:

x = 7

Step-by-step explanation:

-3x+5=-16

    -5  -5

-3x=-21

-3x/3 = -21/-3

Write an equation of the parabola in intercept form that passes through (-2,0.05) with x-intercepts of -7 and -3.

Answers

Answer:

  y = 0.01(x +7)(x +3)

Step-by-step explanation:

For intercepts p and q, the equation will be ...

  y = a(x -p)(x -q)

For the given intercepts, the equation is ...

  y = a(x +7)(x +3)

We can find the value of 'a' by using the given point:

  0.05 = a(-2+7)(-2+3) = 5a

  0.01 = a . . . . divide by 5

The complete equation is ...

  y = 0.01(x +7)(x +3)

-3x + y = 22
-12x – 10y=-10

Answers

Answer:

              x = -5,  y = 7

Step-by-step explanation:

-3x + y = 22     ⇒  y = 3x + 22

-12x - 10y = -10  and  y = 3x + 22

-12x - 10(3x + 22) = -10

-12x - 30x - 220 = -10

               +220       +220

 - 42x  = 210  

 ÷(-42)     ÷(-42)

    x = -5

y = 3(-5) + 22 = -15 + 22 = 7

Answers

Answer:

∠B = 82°

Step-by-step explanation:

(see attached for reference)

recall the property that an exterior angle of a triangle is equal to the sum of its two remote interior angles.

in our case, the exterior angle is obtuse ∠A = 143°

the two remote interior angles are ∠C and ∠B

hence according to our definition above:

143° = ∠C + ∠B  (we are given that ∠C =61°)

hence

143° = 61° + ∠B

143° - 61° =  ∠B

∠B = 82°

Find three equivalent fractions for 2/3 by multiplying by 3/3, 5/5 and 6/6. What property of multiplication do we use to find equivalent fractions?

Answers

The property of multiplication used to find equivalent fractions is called the multiplicative identity. It says that when a number is multiplied by 1, it remains same. When finding equivalent fractions, the numerator and denominator of a fraction is multiplied by the same number. In other words, the fraction is multiplied by 1, hence it remains the same.

The equivalent fractions for 2/3 are 6/9, 10/15, and 12/18 because multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.

What is a fraction?

Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.

It is given that:

2/3 by multiplying by 3/3, 5/5, and 6/6.

= (2/3)(3/3)

= 6/9

= (2/3)(5/5)

= 10/15

= (2/3)(6/6)

= 12/18

The multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.

The numerator and denominator of a fraction are multiplied by the same number for determining equivalent fractions.

Thus, the equivalent fractions for 2/3 are 6/9, 10/15, and 12/18 because multiplicative identity is a feature of multiplication that is used to determine equivalent fractions.

When we add 4 +3 = 7 = 5 +2 . 5 will be carried as 1

4 + 3= 12

In subtraction, 32 - 4

Miguel did the following math problem: 65 ∙ 64 = 369. Which of the following is a true statement? 1.He is correct. 2.He is incorrect because he should have subtracted the exponents. 3.He is incorrect because he should have multiplied the exponents. 4.He is incorrect because he multiplied the bases.

Answers

Answer:

He is incorrect.

Step-by-step explanation:

The correct answer is 4,160.

Answer:

3. He is incorrect because he should have multiplied the exponents.

Step-by-step explanation:

6∧5 × 6∧4 = 369 Incorrect

Correct: 6∧5 = 7776

6∧4 = 1296

7776 × 1296 = 10,077,696

1. He is not correct, therefore the first answer is wrong.

2. You do not subtract the exponents unless one of the exponents is negative and you have the same bases. You have the same bases in this equation, however, neither one of them are negative. Therefore, the second answer is wrong.

3. The third answer is correct because if you were adding the two terms together then you would add the exponents together then multiply the base as many times as needed. However, since you are multiplying the two terms together, you also need to multiply the exponents together. From there, you then multiply the terms and get your answer.

4. The fourth answer is also incorrect because you need to multiply the bases together in order to get a correct answer.
