Answer:
B
Step-by-step explanation:
Any number, regardless of its sign, raised to an even power will always be positive. Therefore, a⁷² will be positive. We know that -3/7 is negative, and since a positive times a negative is negative, the answer will be negative.
Answer: The expression has 3 terms
The expression represents the sum of 9z,4y, and 3x
The expression represents y multiplied by 4 plus x multiplied by 3 plus z multiplied by 9
The second term has a coefficient of 4
Step-by-step explanation:
First, you would have to find your slope. Then you plug your coordinates into the equation to find b. Your final answer is y= -6x+5.
Answer:
Additive
-2 = 2
18 = -18
-30 = 30
2/5 = -2/5
Multiplicative
8/9 = 9/8
12/15 = 15/12
-6 = -1/6
10 = 1/10
Step-by-step explanation:
an<em> additive inverse</em> is a number you must add to another number to get 0
(think of it as the negative version of the number)
<em>{but WHY? In math, you can imagine comparing numbers on a number line. If we are finding the opposite of a number, we want to find the same distance from 0, but on the opposite side of 0. So, 2 would be two to the right of 0, -2 would be two to the left of 0}</em>
-2 + 2 = 0
18 - 18 = 0
-30 + 30 = 0
2/5 - 2/5 = 0
a <em>multiplicative inverse</em> is a number that you multiply by another number to get 1.
We are finding the "reciprocal" of a number; you are essentially flipping it as a fraction
(reciprocal of 2 = 1/2 {remember, 2 is the same thing as 2/1 } ; reciprocal of 1 / 8 = 8)
<em>note: reciprocal is being used interchangeably with multiplicative inverse here</em>
<em />
8/9 · 9/8 = 1
12/15 · 15/12 = 1
-6 · -1/6 = 1 {-6 = -6/1}
10 · 1/10 = 1 {10 = 10/1}
hope this helps!! have a lovely day :)
Answer:
El total que la señora Rina pagó por sus frutas, en términos de b, es:
Step-by-step explanation:
Para resolver este ejercicio, primero sacaremos las variable que nos brindan:
- Costo de la pera = b
- Costo de la manzana = b - 7 (esto se debe a que la manzana cuesta 7 pesos menos que la pera, tal como dice el enunciado).
Ahora, nos centraremos en la compra realizada por la señora Rina, donde se menciona que:
- <em>Compra de la señora Rina = 4 peras + 1 manzana</em>
Ahora, como si esto fuera una ecuación, vamos a reemplazar las manzanas y las peras por las variables que tenemos de su costo:
- Compra de la señora Rina = 4b + b - 7
Y procedemos a operar:
- <u>Compra de la señora Rina = 5b - 7</u> (sumando 4b + b)
Por lo tanto, <u><em>la compra de la señora Rina, en términos de b, le ha costado 5b - 7</em></u>.
