Answer:
infinitely many solutions
Step-by-step explanation:
Given the simultaneous equation
4x=10+4y... 1
2x-2y=15 .... 2
_____________
4x-4y = 10 * 1
2x-2y = 15 * 2
__________--
4x-4y = 10
4x-4y = 30
Add both equation
8x - 8y = 10+30
8x-8y = 40
Divide though by 8
x-y = 5
x = 5 + y
Since the result gave 1 equation and 2 unknowns, then we will let x =k
k = 5 + y
y = k -5
k can be any integer
(x,y) = (k, k-5)
This show that the equation has infinitely many solutions

Use the Law of Sines to write an expression that represents angle measure x.
Answer:
x° = arcsin(15.5/26.9×sin(73°))
Step-by-step explanation:
The law of sines tells you the sine of an angle is proportional to the length of the opposite side:
sin(x°)/15.5 = sin(73°)/26.9
sin(x°) = (15.5/26.9)sin(73°) . . . . . multiply by 15.5
Using the inverse function, we can find x.
x° = arcsin((15.5/26.9)sin(73°))

Answer:
an american football field measures 100 yards long between the endzones,and is 53 1/3 yards wide.is the length of the diagonal across this field more or less than 120 yards . what is the value rounded to the nearest tenth of a yard
Step-by-step explanation:
To solve, you need to use Pythagorean Theorum
a^2+b^2=c^2
100^2+53.33^2 = c^2
10,000+2844.0889=c^2
12844.1=c^2
square root
= 113 1/3 yards
So it is less than 120 yards

Answer:
The mean is 82.727272727273 rounded 83
Step-by-step explanation:
You add all the numbers:
40 + 75 + 80 + 80+ 81 + 84 + 88 + 90 + 92 + 100 + 100= 910
You divide that result by the total of numbers to add, in this case 11
910/11= 82.727272727273
To round any number, consider that if it is 5 or above it you can round it to the nearest hundred.
Just in case

A package designer wants the hexagonal base of a hat box to have an area of
about 200 in.2. About how long is each side?
Answer:
About 9inches long
Step-by-step explanation:
Area of a hexagon = 3√3/2 a²
a is the length of each side
Given
Area of the hexagon = 200in²
Substitute
200 = 3√3/2 a²
200×2 = 3√3 a²
400 = 3√3a²
a² = 400/3√3
a² = 400/5.196
a² = 76.982
a = √76.982
a = 8.774
Hence the length of each side is about 9inches long (to nearest inches)

Are the two expressions in the equation 2b + 5 + 1b = 3b + 5 equal or equivalent? How do you know
Given:
The expression is
[tex]2b+5+1b=3b+5[/tex]
To find:
Whether the two expression in the equation are equal or equivalent.
Solution:
If two expression are exactly the same, then they are equal and if the two expressions are different but the after simplification both are same, then they are called equivalent expressions.
We have,
[tex]2b+5+1b=3b+5[/tex]
Taking LHS, we get
[tex]LHS=2b+5+1b[/tex]
On combining liker terms, we get
[tex]LHS=(2b+1b)+5[/tex]
[tex]LHS=3b+5[/tex]
[tex]LHS=RHS[/tex]
In the given equation both expression are different but after simplification LHS = RHS, therefore the expression are equivalent not equal.
Solve for x: 7x + 3 =2x +13
Answer:
x = 2
Step-by-step explanation:
7x + 3 = 2x + 13
Get all the x on the same side: 7x - 2x = 13 - 3
Subtract: 5x = 10
Divide both sides by 5 to get x = 2.
Plug the found value of x back in to check the answer: 7(2) + 3 = 2(2) + 13
Multiply: 14 + 3 = 4 + 13
Add: 17 = 17
This verifies that x = 2.
Step-by-step explanation:
[tex]7x+3=2x+13\\7x-2x=13-3\\5x=10\\x=2[/tex]
What is f(3) if f(x) = - 4x+1 ?
A.-44
B.-11
C. 1/2
D. 13
Please help me! :/
Answer:
Here is the equation:
f(x)=4x+1f(x)=4x+1
You need to find f(3). To do that, substitute all the x's with 3:
f(x)=4x+1 \rightarrow f(3)=4\times3 + 1f(x)=4x+1→f(3)=4×3+1
The first thing you need to do is multiply 4 by 3. Multiply:
4 \times 3 = 124×3=12
Here is your new equation:
f(3)=12+1f(3)=12+1
To get your answer, you need to add 12 and 1. Add:
12+1 = 1312+1=13
That means:
\bf f(3)=13f(3)=13
Step-by-step explanation:
13 is the ans
