Answer: x = 9, y = -14
Explanation:
4x + y = 16
2x + y = -2<span>
</span> 4x + y = 16
- 2x + y = -2
-------------------
2x + 0 = 18
-------------------
2x = 18
x = 9 <<<<< ¯\_(ツ)_/¯ For the value of x
Plug x = 9 into 2x + y = -2
2(9) + y = -2
12 + y = -2
y = -14 <<<<< ¯\_(ツ)_/¯ For the value of y
Step-by-step explanation:
1 person= $23.98
28 people= 23.98*28
= $671.44
Answer:
8x+2
Step-by-step explanation:
8x+4/2
= 8x+2
because 2 cancel out 4
and because they are not like terms
the answer will be 8x+2
Vertices of the given triangle are: (0, 0) , (8, 0) and (-6, 0)
If we dilate the triangle with a scale factor of 1/2 , then the new vertices will be...
Now we will just plot those vertices for getting the dilated triangle.
the options that are polynomials are:
3.9x³-4.1x² + 7.3
x²y²-4x³+12y
4-x²
<h3>Which algebraic expressions are polynomials?</h3>
A polynomial is an expression of the form:
p(x) = aₙ*xⁿ + ...+ a₂*x² + a₁*x + a₀
Where all the exponents of the variable are whole numbers, and in this case we have only one variable x, but we could have any number of variables.
With that in mind, the options that are polynomials are:
3.9x³-4.1x² + 7.3
x²y²-4x³+12y
4-x²
These 3 expressions are polynomials.
