Assuming this is a system of equations, here is how to find x.
2x + 3y = 45
x + y = 10
Multiply x + y = 10 by 2 so you are able to use the elimination method.
2x + 3y = 45
2x + 2y = 20
Subtract.
y = 25
Now that we've found y, we can plug it in to find x.
x + 25 = 10
Subtract 25 from both sides.
x = -15

C- A cube also cannot be "two polygons"
D- A pyramid is not parallel.
Resolviendo una resta, veremos que el número es igual a 12.
<h3>
¿Como encontrar el número?</h3>
Definamos X como nuestro número, sabemos que cuando este número es disminuido en cuatro (es decir, le restamos 4 a nuestro número X) el resultado es 8.
Entonces, lo que tenemos que hacer es resolver la operación:
X - 4 = 8
Para resolver esto, lo que tenemos que hacer es sumar 4 en ambos lados de esta ecuación, asi obtenemos:
X - 4 + 4 = 8 + 4
X = 12
De esta forma, concluimos que nuestro número es igual a 12.

{(3, –2), (6, 1), (–1, 4), (5, 9), (–4, 0)}
(x, y)
Domain = x
Range = y
Domain = (3, 6, -1, 5, -4)
In case you need the range it is (-2, 1, 4, 9, 0).
Answer: (3, 6, -1, 5, -4)

Answer:
A. 5 is the base
D. 12 is the exponent and tells us how many times we should multiply 5 by itself
Step-by-step explanation:
The given expression is
This is a number written in an index notation.
The base is 5.
The exponent is 12.
The exponent tells us how many times the base multiplies itself.
Therefore means, 5 multiplies itself 12 times.
Options A and D are correct.
