Which statement is true about the solution to the system of equations below? { 2 y = 2 x + 2 4 y = 4 x + 10
Step-by-step explanation:
Given equations are :
2y = 2x + 2 ....(1)
4y = 4x + 10 ....(2)
we need to find the solution of the system of equations.
If the general equation are :
a₁x+b₁y+c₁ = 0
and
a₂x+b₂y+c₂ = 0
[tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}\ne \dfrac{c_1}{c_2}[/tex] (For parallel lines)
Here, a₁ = 2, b₁ = 2, c₁ = 2, a₂ = 4, b₂ = 4 and c₂ = 10
Since, [tex]\dfrac{a_1}{a_2}=\dfrac{b_1}{b_2}=\dfrac{2}{4}\ne \dfrac{c_1}{c_2}[/tex]
Hence, the given system of equation is parallel lines.
Find the area of the
regular figure below:
A) 2,338.3 cm
B) 2.225.8 cm2
C) 2.190.1 cm2
D) 2,458.5 cm
E) 2,603.2 cm2
Answer:
Option A: 2338.3 cm² is the correct answer.
Step-by-step explanation:
Given that:
The given figure is a regular hexagon.
Length of side = 30 cm
Area of a hexagon is given by;
Area = [tex]\frac{3\sqrt{3}}{2}a^2[/tex]
Putting a=30 in the formula
Area = [tex]\frac{3\sqrt{3}}{2}(30)^2[/tex]
Area = [tex]\frac{3\sqrt{3}}{2}*900[/tex]
Area = [tex]3\sqrt{3}*450[/tex]
Area = 2338.26 cm²
Rounding off to one decimal place,
Area = 2338.3 cm²
Hence,
Option A: 2338.3 cm² is the correct answer.

The area of a rectangular painting is 3276 cm squared If the length of the painting is 63 cm what is its width?
Answer:
Width = 52cm
Step-by-step explanation:
Step one:
given data
Area= 3276 cm squared
lenght= 63cm
Required
The width
Step two:
We know that
Area= L*W
substitute
3276= 63*W
divide both sides by 63
W= 3276/63
W=52cm

The mean age of 3 women in an office is 30 years old.
The mean age of 7 men in an office is 33 years old.
What is the mean age (nearest year) of all the people in the office?
Answer:
32 years
Step-by-step explanation:
Here, we simply calculate the age of all first
For all men, we have 7(33) = 231
For all women = 3(30) = 90
So we simply have;
(90 + 231)/10 = 32.1
Approximately 32 years

Which of the following expressions are equivalent to 1/-7 • -6/5
Solve For X
please help, thank you :}
Given:
Two secants intersecting each other outside the side the circle.
To find:
The value of x.
Solution:
Using Intersecting Secant Theorem, we get
[tex]x(x+8)=4(4+8)[/tex]
[tex]x^2+8x=4(12)[/tex]
[tex]x^2+8x=48[/tex]
[tex]x^2+8x-48=0[/tex]
Using splitting the middle terms, we get
[tex]x^2+12x-4x-48=0[/tex]
[tex]x(x+12)-4(x+12)=0[/tex]
[tex](x+12)(x-4)=0[/tex]
Using zero product property, we get
[tex](x+12)=0\text{ and }(x-4)=0[/tex]
[tex]x=-12\text{ and }x=4[/tex]
Side length cannot be negative, i.e., [tex]x\neq -12[/tex].
Therefore, the only value of x is 4.
Are these fractions equivalent or nonequivalent?

Step-by-step explanation:
fifteen subtracted from the product of a number and -4 is at most 32
Answer:
Step-by-step explanation:
Let's use the variable x to represent the unknown number.
Also, the word, "product", indicates multiplication.
In this problem, the product of a number and -4 would be represented as -4 x
The words, "is at most", would be represented as: <
Then to create the inequality, subtract 15:
-4 x - 15 < 32
Now solve the inequality using inverse operations. NOTE - Be sure to reverse the direction of the inequality symbol when multiplying or dividing by a negative number.
4 x - 15 < 32
-4 x - 15 + 15 < 32 + 15
-4 x < 47
-4 x / -4 > 47/-4
x > -47/4
x > -11.75
