solve the system by elimination for 2x-y=11 and 6x-3y=15
The system of equation has no solution.Because the variables in the given equation got canceled during substation.
How can we determine the solution to an equation?We do the identical actions on both sides to ensure that both expressions remain equal. Solving equations entails determining the values of the variables involved for which the equation is valid.
The given equation is;
Equation 1;
[tex]\rm 2x-y=11[/tex]
Equation 2;
[tex]\rm 6x-3y=15[/tex]
From the equation 1 find the value of the y and put in the equation 2 as;
[tex]\rm y=2x-11[/tex]
[tex]\rm 6x-3y=15 \\\\\ 6x-3(2x-11)=15 \\\\\ 6x-6x-33=15[/tex]
From the above equation, it is observed that the variables in the equation got canceled.
Hence, the system of equation has no solution.

−4≤4x+8
(With explanation, I'm confused because I keep getting x≤−3 when the solution is x≥-3.)
Step-by-step explanation:
To solve the inequality:
4x + 8 ≥ -4
4x ≥ -12
x ≥ -3
If this is what you did then I'm not sure how you ended up getting x ≤ -3. You're not dividing by a negative number so the sign never switches.
Hope this helps
Step-by-step explanation:
−4≤4x+8
Subtraction property of inequality with the value 8.
-12≤4x
Division property of inequality with the value of 4.
The reason the sign stays as less than or greater to is because the sign only switches when the DIVISOR is negative, not the dividend.

Find the area of a triangle with vertices A(0, 2), B(8, 2), and C(4, -3).
Answer:
20
Step-by-step explanation:
First, consider (0,2) and (8,2). The y-value is the same for both points. x ranges from 0 to 8, so the length of this horizontal side of the triangle is (8-0), or 8.
Again, this horiz. side has a y-value of 2.
The third point is (4,-3). Therefore the vertical distance from the horizontal line to the third point is 2 - (-3), or 5.
Thus, the "base" of the triangle is 8 and the "height" is 5.
The area is A = (bh)/2. Substitute the values 8 and 5. Simplify your result. Answer: 20 square units.

The current it conduct when it is plugged into a wall outlet that provides 120 V is 10.4A
Ohms lawThe current passing through a conductor is proportional to the potential difference. Mathematically;
V = IR
where
V is the voltage = 120V
R is the resistance = 11.5 ohms
Required
Current I
Substitute
I = V/R
I = 120/11.5

Which one is correct? I'm getting told two different things. Find the value of x
Answer:
x ≈ 25.7
Step-by-step explanation:
using the tangent ratio in the right triangle
tan65° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{12}[/tex] ( multiply both sides by 12 )
12 × tan65° = x , then
x ≈ 25.7 ( to the nearest tenth )
what has at least two pairs of consecutive sides are congruent,diagonals are perpendicular to one another,at least one pair of opposite sides are parallel to one another, and the quadrilateral cannot be inscribed in a circle
The quadrilateral that is described with the given properties is known as; Rhombus
How to identify quadrilaterals?
A quadrilateral is defined as a closed shape and a type of polygon that has four sides, four vertices and four angles.
Now, we are told that at least at least two pairs of consecutive sides are congruent, diagonals are perpendicular to one another.
The only quadrilaterals that fit into thus definition are square and rhombus.
Now, we are told that the quadrilateral cannot be inscribed in a circle. A square can be inscribed in a circle but not a rhombus and as such we can say that the quadrilateral with the given properties is a rhombus,

What is the fully factored form of the expression 45x²y2 + 18x3
Answer:
9x^2(5y^2 + 2x).
Step-by-step explanation:
First find the Greatest Common Factor of the 2 terms.
GCF of 18 and 45 = 9
GCF of x^2 and x^3 = x^2.
The complete GCF is therefore 9x^2.
So, dividing each term by the GCF, we obtain:
9x^2(5y^2 + 2x).

What is the area, in square units, of a trapezoid bounded by the lines $y = x$, $y = 10$, $y = 5$ and the $y$-axis? express your answer as a decimal to the nearest tenth
The area of a trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis is 37.5 square units.
What is the area of the trapezium?A trapezium is a quadrilateral having two opposite sides parallel.
The area of a trapezium is equal to;
[tex]\rm Area =\dfrac{1}{2} \times \text{Distance between the parallel sides} \times \text{Sum of the parallel sides}[/tex]
The trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis.
The vertices are at (0,10), (10,10),(5,5) and (0,5)
You need to find the area of the rectangle (0,10) (10,5) (0,5) and (5,5)
The lengths are 5, 5,5,5.
The area of the legs is = 5 × 5 =25
The area is;
[tex]\rm Area =\dfrac{1}{2} \times \text{Distance between the parallel sides} \times \text{Sum of the parallel sides}\\\\Area =\dfrac{1}{2} \times 5 \times 5\\\\Area =12.5[/tex]
And the right triangle (10,5),(5,5), and (10,10) the right angle is at (10,5)
the two legs are lengths 5 and 5
so together they are 25 +12.5=37.5 square units.
Hence, the area of a trapezoid is bounded by the lines y = x, y = 10, y = 5, and the y− axis is 37.5 square units.
