Answer:
D) y= -1/2x+9
Step-by-step explanation:
if u substitute y with 8 u will get 2
if u substitute y with 5 u will get 8
Answer:
D
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}=xy_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (2, 8) and (x₂, y₂ ) = (8, 5)
m = [tex]\frac{5-8}{8-2}[/tex] = [tex]\frac{-3}{6}[/tex] = - [tex]\frac{1}{2}[/tex]
The line crosses the y- axis at (0, 9) ⇒ c = 9
y = - [tex]\frac{1}{2}[/tex] x + 9 → D
which equation can be used to solve for x
Answer:
x+41=90
Step-by-step explanation:
Because that is square which means 90 degrees so 41 degrees plus x equals to 90
Hi there!
»»————- ★ ————-««
I believe your answer is:
The second option, [tex]\boxed{x+41=90}[/tex].
»»————- ★ ————-««
Here’s why:
In the picture given, there are two angles that, together, make up a right angle. You can also tell that it is a right angle because of the box marked in the bottom left corner. The angles in the picture are also complementary angles. Complementary angles add up to 90°. Right angles measure 90°.⸻⸻⸻⸻
We can use the information given to set up an equation.
[tex]\boxed{\text{An equation to find 'x'.}}\\\\\text{The sum of the angle's measurements: }90$^{\circ}$\\\\\text{The given measurement for one of the angles: }41$^{\circ}$\\\\----------------\\\\\underline{The sum of the two angle measurements would be 90 degress.}\\\\\text{Given angle mesurement} + x = 90\\\\\boxed{41 + x = 90}[/tex]
Option B matches the equation made. Therefore, option B should be the correct answer.

4x-2=-13 solve for x
Answer:
x = -11/4
Step-by-step explanation:
4x - 2 = -13
(add 2 on both sides)
4x - 2 + 2 = -13 + 2
4x = -11
(Divide 4 on both sides)
4/4x = -11/4
x = -11/4
Answer:
ANSWER :-[tex]4x - 2 = -13\\4x = -13 + 2\\4x = -11\\x = - \frac{11}{4} \\x =- 2.75\\[/tex]
The value of x is - 11/4 in fraction form & - 2.75 in standard form.

algebraic expressions x+2/x2+x-3/x2-x-2 find the l.c
m
m
Answer:
= x^2-3x-4/x(x+1)(x-2)
Step-by-step explanation:
x+2/x2+x - 3/x2-x-2
=x+2/x(x+1) - 3/x^2-x-2
=x+2/x(x+1) - 3/x^2-2x+x-2
= x+2/x(x+1) - 3/x(x-2)+1(x-2)
= x+2/x(x+1) - 3/(x+1)(x-2)
Find the LCM
= (x+2)(x-2)- (3x)/x(x+1)(x-2)
= (x+2)(x-2)- (3x)/x(x+1)(x-2)
= x^2-4-3x/x(x+1)(x-2)
= x^2-3x-4/x(x+1)(x-2)

Answer:
No it's not compulsory.
Step-by-step explanation:
If the ratio of sides are given then that can also help you find angle. Not only that if the relationship between the perpendicular and base are given then you can find angle
E.g.
if the ratios of the sides is 5:4:3 then you can find the angle

PN = LO
__________________________
(LO)^2 = (LN)^2 + (NO)^2
(LO)^2 = 6^2 + 8^2
(LO)^2 = 36 + 84
(LO)^2 = 100
LO = √100
LO = 10
__________________________
Thus :
PN = 10
Step-by-step explanation:
So, we can assume that LN and PO are equal in length and NO and LP are equal in length as well. LO and PN are also equal.
We can see that PN is the hypotenus of either triangle NLP or NOP. LO is the hypotenuse of LOP and LON, so those could be used to find the length as well. I rather work with NOP, but any work.
We know that NO is 8 units long and LN is 6 units long. Because LN = PO, PO = 6 units.
So, using the pythagorean theorem, the hypotenuse is:
8^2 + 6^2 = c^2
64 + 32 =c^2
sqrt(96)=c
c~9.8
I don't know how exact they want your answer.
c = 9.79795897113

The terminal side of O is in quadrant Il and sin 5/13 = . What is cos 0?
A. 5/12
B.12/13
C.-5/12
D-12/13
If the terminal side of θ is in quadrant || and sin θ = 5/13, then the value of cos θ = -12/13.
Given that,
Terminal side of θ is in quadrant ||.
Sin θ = 5/13
We have the trigonometric identity,
sin² θ + cos² θ = 1
Substituting the value of Sin θ = 5/13, we get,
(5/13)² + cos² θ = 1
cos² θ = 1 - (5/13)²
= 1 - 25/169
= 144/169
cos θ = √ (144/169)
= ± 12/13
We have the terminal side of θ is in second quadrant. In the second quadrant, all the trigonometric values except sin are negative.
So, cos θ = -12/13

Which of the following choices is the standard deviation of the sample shown
here?
18, 19, 20, 21, 22
A. 2
B. 12.5
C. 20
D. 2.5
E. square root of 2
Answer: E. square root of 2
We can write that in shorthand as sqrt(2)
sqrt(2) = 1.41421 approximately
======================================================
Explanation:
Step 1)
Add up the values to get 18+19+20+21+22 = 100
Divide by n = 5, since there are 5 items in the list. So 100/n = 100/5 = 20
The sample mean is xbar = 20
--------------
Step 2)
Subtract the mean from each data value
18 - xbar = 18 - 20 = -219 - xbar = 19 - 20 = -120 - xbar = 20 - 20 = 021 - xbar = 21 - 20 = 122 - xbar = 22 - 20 = 2The results we get are: -2, -1, 0, 1, 2
---------------
Step 3)
Square the results from the previous step
(-2)^2 = 4(-1)^2 = 1(0)^2 = 0(1)^2 = 1(2)^2 = 4The results here are: 4, 1, 0, 1, 4
---------------
Step 4)
Add up those squares from the previous step: 4+1+0+1+4 = 10
Now divide by n = 5 to get 10/n = 10/5 = 2
The result 2 represents the population variance. Applying the square root to the population variance leads to the population standard deviation. So we end up with the final answer of sqrt(2). The answer is choice E.
sqrt(2) = 1.41421 approximately
---------------
Note: if you want the sample standard deviation, then you divide by n-1 = 5-1 = 4, but the other steps are the same as before.
