D. (6,0)

Answers

Answer 1

Answer:

The ordered pairs are (-9,-12) and (6,0) satisfying the equation 4x – 5y = 24. The correct option is A and D.

What is an expression?

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given expression is 4x – 5y = 24. We will check the points as:-

4x – 5y = 24

Use:- (-9,-12)

( 4 x -9 ) - ( 5 x 12) = 24

-36 - 60 = 24

24 = 24

4x – 5y = 24

Use:- (6,0)

( 4 x 6 ) - 0 = 24

24 = 24

Therefore, the ordered pairs are (-9,-12) and (6,0) satisfying the equation 4x – 5y = 24. The correct option is A and D.

Answer 2

Answer: Plug the values into the equation and check if it's true.

$(x,y)=(-9,-12) \n4 * (-9) -5 * (-12) \stackrel{?}{=} 24 \n-36+60 \stackrel{?}{=} 24 \n24 \stackrel{?}{=} 24 \n24 = 24 \na \ solution \n \n(x,y)=(1,-4) \n4 * 1 - 5 * (-4) \stackrel{?}{=} 24 \n4+20 \stackrel{?}{=} 24 \n24 \stackrel{?}{=} 24 \n24=24 \na \ solution$

$(x,y)=(4,8) \n4 * 4 - 5 * 8 \stackrel{?}{=} 24 \n16-40 \stackrel{?}{=} 24 \n-24 \stackrel{?}{=} 24 \n-24 \not= 24 \nnot \ a \ solution \n \n(x,y)=(6,0) \n4 * 6- 5 * 0 \stackrel{?}{=} 24 \n24 -0 \stackrel{?}{=} 24 \n24 \stackrel{?}{=} 24 \n24=24 \na \ solution$

The answers are A, B and D.

The scientific notation 2 x 10-2 has what value?

Answers

Since the exponent is negative, you move the decimal (2.0) to the left two spots leaving you with .02

2(10^-2)

=2 * 10^-2

= 2 * 1/10 * 10

= 2/10 * 10

= 2/10^2

= 2/100

= 1/50 Decimal: 0.02

A: The scientific notation 2 x 10^-2 has the value of 0.02

Help!!!! How do I solve this

Answers

Answer:

-11

Step-by-step explanation:

So, using the fact that one x intercept is 7, and the vertex is (-2,-4), we can solve for the other x intercept. While there are many ways to solve this, the way I prefer to do it is to realize that the x intercepts are the same distance away from the vertex. this means that if the vertex is at x = -2, and one x intercept is at x = 7, the other will be at -11, as 7+2 = -2+11.

I’m pretty sure that the other x-intercept is -7

A recipe for trail mix uses 7 ounces of almonds with 5 ounces of raisins. How many ounces of almonds would be in a one pound bag of this trail mix

Answers

The number of ounces of almonds would be in a one pound bag of this trail 9 1/3 ounces

Given:

Almonds = 7 ounces

Raisins = 5 ounces

Ratio of almonds to raisins = 7 : 5

Total ratio = 7 + 5

= 12

Total mixture = 1 pounds

= 16 ounces

1 pound = 16 ounces

Quantity of almonds in 1 pound mix = Ratio of almonds / Total ratio × Total mixture

= 7/12 × 16

= (7 × 16) / 12

= 112 / 12

= 9 1/3 ounces

Therefore, number of ounces of almonds would be in a one pound bag of this trail is 9 1/3 ounces

brainly.com/question/12527870

Answer: In your mix, you have 7 ounces of almonds and 5 ounces of raisins, which adds to 7 + 5 = 12 ounces of mix.

Because we want to know the proportion of almonds, then if 12 is the total amount, 7/12 is the proportion of almonds in the mix, this is 7/12 = 0.583

In one pound there are 16 ounces, so in one pound of mix you have 16 ounces of it. Now you know the proportion of almonds in a mix is of 0.583, then you multiply this by the ounces of mix and you get the ounces of almonds in it:

0.583*16 = 9.33

then you have 9.33 ounces of almonds in one pound of mix.

Answers

to compare you need to equalize the denominators
when you do it you will see the biggest number is 5/6.

Judy did, she had more drink, so she drank the most of it because 5/6 is greater than 2/3 an 2/3 is greater than 1/2 (Plz if u appreciate, mark me brainliest :) :)!!!)

the set of all natural numbers, the set of all whole numbers, the set of all integers, the set of all rational numbers, and the set of all real numbers

Answers

Answer:

Option C (the set of all integers, the set of all rational numbers, and the set of all real numbers).

Step-by-step explanation:

The value of square root of 9 is ±3. This means that there two answers to square root of 9: 3 and -3.

As far as 3 is concerned, it is one of the elements of the natural number set. It is already known that natural numbers are also whole numbers, also integers, also rational numbers, and also real numbers.

As far as -3 is concerned, it is not a natural number since the set of natural numbers does not contain negative numbers. -3 is an integer. Which means that -3 is also a rational number and also a real number.

After identifying the common sets and taking the intersection of both the above classifications, it yields the set of all integers, the set of all rational numbers, and the set of all real numbers, Therefore, Option C is the correct answer!!!

Answer:

the set of all integers, the set of all rational numbers, and the set of all real numbers
