What is the graph of the system Y â 2x 3 and 2x 4y â 8?
The graph of the system of equations y = -2x + 3 and 2x + 4y = 8 is a pair of straight lines passing through the points (2/3, 5/3).
y = -2x + 3 …. (1)
2x + 4y = 8 …. (2)
Substitute eqn (1) in (2)
2x + 4 (-2x + 3) - 8 = 0
Using the multiplicative distributive property, we get
2x - 8x + 12 = 8
By rearranging the above eqn, we get
2x - 8x = 8 - 12
-6x = - 4
Dividing both sides by -2, we get
3x = 2
x = 2/3
Put the value of x in eqn (1)
y = -2 (2/3) + 3
y = -4/3 + 3
y = (-4 + 9)/3
y = 5/3

Is it possible to form a triangle whose sides are 3.5 cm 4.5 cm 7.5 cm long?
A triangle can be formed with the side length of 3.5 cm, 4.5 cm and 7.5 cm.
The one side of the triangle should always measure lower than the sum of remaining two sides of triangle. Based on this concept, let's check the sum and compare it with remaining side to find the possibility of triangle construction.
Side a + side b > side c

What is quadratic equation?Quadratic equation is a second-order polynomial equation in a single variable x ax2+bx+c=0. with a ≠ 0 . Because it is a second-order polynomial equation the fundamental theorem of algebra guarantees that it has at least one solution
Let's take a look at the first choice:
2(x² + 6x + 9) = 3 + 18
Now, we will multiply 2 with every member of the other multiplier on the left side:
2·x² + 2·6x + 2·9 = 3 + 18
2x² + 12x + 18 = 3 + 18
2x² + 12x - 3 = 18 - 18
2x² + 12x - 3 = 0
Let's take a look at the second choice:

The angle of elevation to a nearby tree from a point on the ground is measured to be 63 degrees. How tall is the tree if the point on the ground is 22 feet from the tree? Round to the nearest foot.
The height of the tree is 43.7 feet
How to calculate the height of the tree?Height deals with the length of the tree vertically.
The given parameters that will help us solve the problem are
The angle of elevation = 63 degrees
The distance from the foot of the tree to the point is 22 feet
Using the trigonometrical ratio
Tan ∅ = Opposite/Adjacent
Tan63 = h/22⁰
Height of the tree = 22*tan63
The height of the tree is equal = 22*1.9626
Height = 43.7 feet

Based on the estimates above, they sold 3 left-handed and 17 right-handed gloves.
Howmany right-handed gloves were sold?17 right-handed gloves and 3 left-handed gloves were sold.
We must create a set of equations to address this issue.
The total number of gloves sold was 12, and the total income was 940.
Gloves for the right hand (x) = 45.
gloves for the left hand (y) = 50.
Equations x+y=20...
45x + 50y = 561 is the first equation (ii)
Equation derived from equation I x + y = 12 – y (iii)
Equation (ii) becomes 45x + 50y = 940
by substituting equation (iii):
x = 12 - u 45
(12 - y) + 50y = 940;
540 - 45y + 50y = 940;
540 + 7y = 561;
7y = 21 y = 3
Equation I becomes x + y = 20 for y = 3, x + 3 = 20x, and 20- x = 17.

Which TWO number sentences could be used to find the total number of balloons Stella bought?
Answers:
(6×10)+(6×5)
6×10+56
(3×10)+(6×5)
(15×3)+(15×3)
6+15
Answer:
"Choices A & D": (6 x 10) + (6 x 5). & (15 x 3) + (15 x 3) are the correct number sentences.
Step-by-step explanation:
1. How many balloons are there in total?The total amount of balloons can be found via cross-multiplication. To cross-multiply fractions, we multiply the numerator of the first fraction with the denominator of the second fraction and the numerator of the second fraction with the denominator of the first fraction.If one package has 15 balloons, how many balloons do 6 packages have?:[tex]\frac{1 package}{6 packages} = \frac{15 balloons}{X balloons}[/tex][tex]\frac{1 package xX balloons}{1 package} = \frac{6 packages x 15 balloons}{1 package}[/tex][tex]6 x 15 balloons = 90 balloons.[/tex]So now we know there are 90 balloons in 6 packages. 2.

5. Subtraction, ie. 10-5.
3. Find the TWO NUMBER SENTENCES that can be evaluated to 90.Number Sentences:
a. (6 x 10) + (6 x 5).
According to PEMDAS. We multiply the numbers inside the parentheses first.ii. 6 x 10 = 60.
iii. 6 x 5 = 30.
iv. Then we add the products.
v. 60 + 30 = 90.
vi. So this choice IS CORRECT.
b. 6 x 10 + 5.
According to PEMDAS. We multiply first.ii. 6 x 10 = 60.
iii. Then we add the product to 5.
iv. 60 + 5 = 65.
v. 65 DOES NOT equal 90 so this is one of the incorrect number sentences.

According to PEMDAS. We multiply the numbers inside the parentheses first.ii. 3 x 10 = 30.
iii. 6 x 5 = 30.
iv. Then we add the products.
v. 30 + 30 = 60.
vi. 60 DOES NOT equal 90 so this is one of the incorrect number sentences.

In the triangle, suppose that m angle d = (4x-4), m angle e = (6x-3) and m angle f =x
A write an equation to find x. Make sure you use an “=“ sign in your answer
B find the degree measure of each angle
The degree measures of angles d, e, and f are 64 degrees, 99 degrees, and 17 degrees, respectively.
What is the measures of the angles in a triangle?
If we add all three angles in any triangle we get 180 degrees. So, the measure of angle A + angle B + angle C = 180 degrees. This is true for any triangle in the world of geometry.
A) The sum of the angles in a triangle is 180 degrees. Using this fact, we can write:
m∠d + m∠e + m∠f = (4x-4) + (6x-3) + x = 11x - 7
Since this is the sum of the angles in the triangle, it must equal 180 degrees. Therefore, we can write:
11x - 7 = 180
Solving for x:
11x = 187
x = 17
Therefore, x = 17.
B) Now that we know x, we can find the measure of each angle by substituting it into the expressions given for each angle:
m∠d = 4x - 4 = 4(17) - 4 = 64 degrees
m∠e = 6x - 3 = 6(17) - 3 = 99 degrees
m∠f = x = 17 degrees
Therefore, the degree measures of angles d, e, and f are 64 degrees, 99 degrees, and 17 degrees, respectively.

For instance, the inner angles of a square are all exactly 90 degrees, or the right angle. Triangles always have three inner angles that add up to 180 degrees.

The polynomial equation kx^2 - 2x^4 = 0 has no real solutions, for any non-zero value of k.
The equation kx^2 - 2x^4 = 0 has the form of a polynomial equation, where k and x are variables. To find the nonzero value of k that will cause the equation to have 2 real solutions, we need to analyze the roots of the equation.
The roots of the equation are the values of x that make the equation equal to zero. To find the roots, we can set each factor of the polynomial equal to zero and solve for x:
kx^2 = 0 and 2x^4 = 0
The first equation gives us x = 0, which is not a valid solution, because it is not a real number.
The second equation gives us x^4 = 0, then x = 0. But x = 0 is not a valid solution for this equation, as it is not a real number.
Therefore, the polynomial equation kx^2 - 2x^4 = 0 has no real solutions, for any non-zero value of k.

Three sides and three corners define a triangle as a polygon. The triangle's corners are defined as the locations where the three sides converge. 180 degrees is the result of multiplying three triangle angles.]
in the triangle
If AL = 2, LS = 6,LM = 4, and ST=x+ 2,
as its given, M is the mid point and LM || ST
so LM = ST
4 = (x + 2)
2 = x
ST = 4
