Answer:
No solutions.
Step-by-step explanation:
When given the following system of equations,
[tex]\left \{ {x-2y=-2} \atop {3x-6y=30}} \right.[/tex]
Solve by the process of elimination. The process of elimination is when one manipulates one or both of the equations such that one of the variables is the inverse of the other variable in its corresponding equation. When one adds the system, one of the variables will cancel, and one can solve for the other variable, then back solve for the canceled variable.
In this case, one can see that all terms in the second equation have a common factor of (3), to make manipulating the equation easier, divide the entire equation by (3).
[tex]\left \{ {{x-2y=-2} \atop {3x-6y=30}} \right.[/tex]
[tex]\left \{ {{x-2y=-2} \atop {x-2y=10}} \right.[/tex]
However, in doing so, one can see that the left sides of the equation are equal, however, the right side is not. Such a statement is not possible, thus there are no solutions to this system of equations.
Find the value of the variables please please help me out I will mark you the brainly!
Answer:
h = 110, k =70°
Step-by-step explanation:
the whole circle has 360° so
h= 360-250 = 110
k= 1/2 (250-110) = 70°

4) Solve for w: P = 4L + 4W
Answer:
Rewrite the equation as 4L+4W=P.
4L+4W=P
Subtract 4L from both sides of the equation.
4W=P−4L Divide each term by 4 and simplify.
W=P/4−L
Step-by-step explanation:
Answer:
w=frac{ p-41}{ 4}

Answer:
1. Angle of depression
2. Angle of elevation
3. Angle of depression
4. Angle of elevation
5. Angle of depression
6. Angle of elevation
7. Angle of depression
8. Angle of elevation
9. x=95.8 ft
10. x=173.2 ft
11. x=60ft
12. x=35.0
Step-by-step explanation:Questions 1-8:I don't know how to explain, I'm sorry.
But if the angle is above the flat line which represents something's straight line of vision, it's a angle of elevation. If it's below, it's an angle of depression.
Question 9:Using SOH CAH TOA, I can tell that the angle is going to use CAH.
I wrote the formula Cos40°=x/125
To isolate the x, I multiplies both sides by 125.
125Cos40°=x
I inserted my new equation into desmos, and I got 95.75555539, which I proceeded to round to 95.8.
Question 10:Using SOH CAH TOA again, I can tell that the angle is going to use TOA.
I wrote the formula Tan30°=x/300
To isolate the x, I multiplies both sides by 300.
300Tan30°=x
I inserted my new equation into desmos, and I got 173.2050808, which I proceeded to round to 173.2.
Question 11:For this problem, I noticed that it was a isotopes right triangle, so the two legs will be congruent.
One of the legs was 60, so the other leg must also be 60.
Question 12:Using SOH CAH TOA again, I can tell that the angle is going to use TOA.
I wrote the formula Tan25°=x/75
To isolate the x, I multiplies both sides by 75.
75Tan25°=x
I inserted my new equation into desmos, and I got 34.97307436, which I proceeded to round to 35.0.
Please note that I am also not 100% positive about my answers.

what is the solution(s) to the equation 5a^2 - 44 = 81
Answer:
a=5,a=-5
Step-by-step explanation:
Answer:
5,-5 or C
Step-by-step explanation:
5a² - 44 = 81
Add 44 to both sides of the equation.
5a² = 81 + 44
Simplify.
5a² = 125
Divide both sides by 5, so that we get a² isolated.
a² = 125/5
Simplify.
a² = 25
a = √25
So, a = 5 AND a = -5
It could be both because remember, 5 × 5 = 25, and -5 × -5 = 25, therefore making the statement true.

If 64x=82, what is the value of x?
Round your answer to three places.
Answer:
1.28
Step-by-step explanation:
First, you need to do 82/64, which will give you just x. Then, you need to round to three places. Without rounding it would be 1.28125
So with rounding it would be 1.28. Hope this helps and Happy learning!
If f(x)=l 2x-4 l, find f(-7).

Given square WXYZ. If ZY = 20, find WV. Write your response in the form WV=_____.
Answer:
14.14
Step-by-step explanation:
Recall :
The sides of a square are always equal ;
Since all sides are equal, the the diagonal of the square will be :
XZ² = XY² + WX²
XZ² = 20² + 20²
XZ² = 400 + 400
XZ² = 800
XZ = √800
XZ = 28.28
WY = XZ
WV = 1/2 WY
WV = 1/2 * 28.28
WV = 14.14

Answer:
(10 + s) / 4 =
Step-by-step explanation:
Answer:
(10+s)/4
Step-by-step explanation:
So first, you have to add 10+s. You have to put this in parentheses, since you have to divide 4 by the "result", which would be 10+s. So, the correct answer is (10+s)/4.

Answer:
[tex]\sqrt{360}[/tex]
Step-by-step explanation:
Use Pythagorean Theorem:
[tex]a^2+b^2=c^2[/tex]
Plug in a=18 and b=6
[tex]18^2+6^2=c^2[/tex]
Simplify
[tex]360=c^2[/tex]
Thus when you square root both sides, you will get:
[tex]c=\sqrt{360}[/tex] which is also equivalent to 18.97 or [tex]6\sqrt{10}[/tex]
