I have the equation.
16x^0+2x^2*y^-1
How do I solve the equation if x = 2 and y = 4?
Answer:
18
Step-by-step explanation:
[tex] \\ \sf16 {x}^{0} + 2 {x}^{2} \times {y}^{ - 1} [/tex]
Now putting the values of x and y.
[tex] \\ \sf16 \times {2}^{0} + 2 \times {2}^{2} \times {4}^{ - 1} [/tex]
[tex] \\ \sf = 16 \times 1 + 2 \times 4 \times \frac{1}{ {4}}[/tex]
[tex] \\ \sf = 16 + 2[/tex]
[tex] \\ \sf = 18[/tex]
Note:
•If the power of a number is 0 then it's value will be 1.
•If the power of a number is negative then reciprocal the number to make the power positive.

Answer:
a is less than or equal to 7
Step-by-step explanation:
This is the case because we can treat the less than or equal to sign as an equal sign. The only time it changes is when we divide by a negative, but we do not do that in this problem. First, you subtract 7 from both sides. That leaves us with a 4a on one side and a 28 on the other. Then, you divide both sides by four to get a is less than or equal to 7. I hope this helps!

Which point is an x-intercept of the quadratic function
f(x) = (x – 3)(x + 2)?
A(3, 0)
B(0, 2)
C(0, -2)
D(-3, 0)
Answer:
A
Step-by-step explanation:
The x-intercepts are the roots of a parabola. Specifically, when a parabola is in the form [tex]f(x)=(x-h)(x-k)[/tex], where h and k are real numbers, the roots are [tex](h, 0)[/tex] and [tex](k, 0)[/tex].
Our parabola has a plus, though. That's a problem, right?
No! [tex]x+2=x-(-2)[/tex], so there's no problem. So, our roots are [tex](3, 0)[/tex] and [tex](-2, 0)[/tex].
So, the answer is A and we're done!

Answer:
infinite solution
Step-by-step explanation:
-2 times x is -2x
-2 times 3 is -6
-2 times x is -2x
-2 times 1 is -2
the equation now looks like this:
-2x-6=-2x-2-4
Simplify
-2x-6=-2x-6
0=0
So this is an infinite solution

Al simplificar la expresión -3(a – b) + 5b – {2a + b + [a – 3b – (2b – a) + 5b] – a}, se obtiene:
Al simplificar la expresión-3 (a - b) + 5b - {2a + b + [a - 3b - (2b - a) + 5b] - a}, se obtiene: - (6a + 7b)
La simplificación de expresiones algebraicas requiere la eliminación de los corchetes por sus factores de multiplicación seguido de la combinación y agrupación de los términos semejantes en suma y resta.
De la información proporcionada:
= -3 (a - b) + 5b - {2a + b + [a - 3b - (2b -a) + 5b] - a}El primer paso es abrir los soportes de adentro hacia afuera.
i.e.
= -3a + 3b + 5b - {2a + b + [ a - 3b - 2b + a + 5b] - a}= - 3a + 3b + 5b - {2a + b + a - 3b - 2b + a + 5b - a}= - 3a + 3b + 5b -2a - b - a + 3b + 2b - a -5b + aAhora, el siguiente paso es la reorganización;
= - 3a - 2a - a - a + a + 3b + 5b - b + 3b + 2b - 5b= - 6a - 7b
Por factorización;
= - (6a + 7b)
Por tanto, podemos concluir que la simplificación de la expresión anterior es - (6a + 7b).

Answer:
Step-by-step explanation:
=−8x2−258x+2673
Please help me with this answer ASAP
Step-by-step explanation:
first let's bring the equation into "normal" form :
x - 2y = 2
-2y = 2 - x
2y = x - 2
y = x/2 - 1
so, the slope of this line is 1/2 (the factor of x - that is always the case in all lines).
a parallel line must have the same slope, of course.
so, its equation is
y = x/2 + b
now, b will be different to the -1 of the original equation, or the lines are identical.
it is the point of interception of the line through the y-axis (x = 0).
we get this by using the coordinates of the given point (4, -3).
so,
-3 = 4/2 + b = 2 + b
b = -5
therefore, the formula for the parallel line is
y = x/2 - 5
Help please! I need this done soon
Answer:
y = 3
Step-by-step explanation:
It has to be parallel to the x axis
the coordinates to the point is (6,3)
so to be parallel to x-axis y must always be 3 in this question
so y = 3 is the answer

Liam knows the key to making creamy risotto, a rice dish, is to add the liquid to the rice gradually. He adds 5 ladles of chicken broth to his rice before adding seasoning, and he continues to add 2 ladles of broth each minute afterwards.Write an equation that shows the relationship between the number of minutes since Liam added the seasoning, x, and the total number of ladles of broth he has added, y.
The equation that shows the relationship between the number of minutes and total number of ladles of broth is y = 2x + 5
Let x represent the number of minutes and y represent the total number of ladies.
Since he adds 2 ladles of broth each minute and he has 5 ladies initially, hence:
y = 2x + 5
The equation that shows the relationship between the number of minutes and total number of ladles of broth is y = 2x + 5
