What is y-10=9(x+8) written in standard form?
Answer:
y - 9x - 82 = 0
Step-by-step explanation:
Given expression;
y - 10 = 9(x + 8)
Find:
Write into standard form
Computation:
Given expression;
⇒ y - 10 = 9(x + 8)
Using BODMAS role
Multiply 9 into (x - 8)
⇒ y - 10 = 9(x) + 9(8)
⇒ y - 10 = 9x + 72
⇒ y - 9x - 10 = 72
⇒ y - 9x = 72 + 10
⇒ y - 9x = 82
⇒ y - 9x - 82 = 0
Standard form of given expression
y - 9x - 82 = 0

If sin theta = 8/17 and cot theta < 0, what is sec theta?
Answer:
[tex]-\frac{17}{15}[/tex]
Step-by-step explanation:
By definition, [tex]\cot \theta=\frac{1}{\tan \theta}[/tex] and [tex]\sec \theta=\frac{1}{\cos \theta}[/tex]. Since since [tex]\cot \theta[/tex] is negative, [tex]\tan \theta[/tex] must also be negative, and since [tex]\sin \theta[/tex] is positive, we must be in Quadrant II.
In a right triangle, the sine of an angle is equal to its opposite side divided by the hypotenuse. The cosine of an angle in a right triangle is equal to its adjacent side divided by the hypotenuse. Therefore, we can draw a right triangle in Quadrant II, where the opposite side to angle theta is 8 and the hypotenuse of the triangle is 17.
To find the remaining leg, use to the Pythagorean Theorem, where [tex]a^2+b^2=c^2[/tex], where [tex]c[/tex] is the hypotenuse, or longest side, of the right triangle and [tex]a[/tex] and [tex]b[/tex] are the two legs of the right triangle.
Solving, we get:
[tex]8^2+b^2=17^2,\\b^2=17^2-8^2,\\b^2=\sqrt{17^2-8^2}=\sqrt{225}=15[/tex]
Since all values of cosine theta are negative in Quadrant II, all values of secant theta must also be negative in Quadrant II.
Thus, we have:
[tex]\sec\theta=\frac{1}{\cos \theta}=-\frac{1}{\frac{15}{17}}=\boxed{-\frac{17}{15}}[/tex]
Which ordered pair would form a proportional relation ship with the point graphed below (-10, -40)
Answer:
(5,20)
Step-by-step explanation:
Looking at the pair, we can see that the value of y is simply the value of x multiplied by 4
so we have to multiply the value of x by 4 to get the value for y
So any of the options we can see this proportional relationship is correct
Looking at the options, we can see the third option. (5,20)
20/5 is 4 which makes the option correct
Please help ASAP !!!
Answer:
C
Step-by-step explanation:
the domain is for which values of x is that function defined (is that a valid function).
the range is what values that function can produce based on all the different x-values as input.
so, checking option A
that means all x values are negative.
that means all values inside the square root are negative.
the resulting function values are a discussion class of numbers and not part of the interval of (0, infinity).
so, it cannot be A.
checking option B
the domain range includes the value 6 for x.
but that would make this function for x=6 an invalid expression of 1/0
so, it cannot be B.
checking option C
the value range for x (domain) is x>6 (and excluding x=6).
and the result range is all positive numbers including 0.
there is no violation of any function principle.
the answer is C.
checking option D
similar to C, but the result range is defined as all numbers, negative and positive.
but for the domain the function can never produce negative numbers.
so, it is not D.
Please help, find the area of the polygon.
Answer:
126cm²
Step-by-step explanation:
first divide the figure into two( rectangle and a triangle)
area of a rectangle=length x width
16cmx7xcm
112xcm²
area of a triangle=1/2base x height
1/2x7cmx(20-16)cm
1/2x7cmx(4)cm
14cm²
total area of the figure=area of rectangle+area of triangle
=112cm²+14cm²
=126cm²

Indicate the equation of the given line in standard form, writing the answer in the equation box below.
The line containing the longer diagonal of a quadrilateral whose vertices are A(2, 2), B(-2,-2), C(1, -1), and D16, 4).
9514 1404 393
Answer:
x -3y = 4
Step-by-step explanation:
A plot of the points reveals the longer diagonal to be BD. (Also, point C is on that line.)
We can write the standard form equation of the line through (x1, y1) and (x2, y2) as ...
(y2 -y1)x -(x2 -x1)y = (y2 -y1)x1 -(x2 -x1)y1
For points (-2, -2) and (16, 4), this equation is ...
(4 -(-2))x -(16 -(-2))y = (4 -(-2))(-2) -(16 -(-2))(-2)
6x -18y = -12 +36
Dividing by the greatest common factor (6), we have the standard-form equation ...
x -3y = 4
What is the explicit formula for this arithmetic sequence?
-10,-17, -24, -31, ...
Answer:
D
Step-by-step explanation:
The starting term is a1.
That's the very first term.
a1 = - 10
The second term = -17 which means that you added - 7 to - 10.
So d must be - 7
The formula must be
an = a1 + (n - 1)*d
an = -10 + (n - 1)(-7)
You might wonder why it is n - 1. The reason is because the first term is already added on the right side. The -1 means that we have already included the first term.
We should try the formula out to see what it does. Let's find a4
a4 = -10 + (4 -1)*-7
a4 = -10 + 3(-7)
a4 = -10 - 21
a4 = - 31 which is what the question suggests.

Answer:
m = - 2
Step-by-step explanation:
First coordinate : ( -2 , 9 )
Second coordinate : ( 1 , 3 )
Formulae : m=(y2-y1)/(x2-x1)
Substituting,
m = ( 3 - 9 ) / ( 1 + 2 )
m = - 6 / 3
m = - 2

In the diagram below, the area of $\triangle BCD$ is 60. What is the length of side $\overline{BC}$?
Area of triangle = 1/2 bh
60 = 1/2 (15) h
8 = h
Quadrilateral area = h x (b1 + b2)/2 = 8 x (15+9)/2 = 96 sq units
96 -60 = triangle BAD area = 36 sq units
The length of side BC in the triangle BCD is 8.
What is an area?An area is the amount of space occupied by a two dimensional shape or figure.
From the diagram:
Area of triangle BCD = (1/2) * base * height = (1/2) * CD * BC
60 = (1/2) * 15 * BC
BC = 8
The length of side BC in the triangle BCD is 8.

14/[(π)*(3)^2* 3]= .16 of the cylinder... 3*(0.16) = .48

What is the measure of A
Given:
A figure of a triangle.
To find:
The measure of angle A.
Solution:
Label the points in the figure as shown below.
In the below figure,
[tex]\angle ACB\cong \angle DCE[/tex] (Vertically opposite angles)
[tex]m\angle ACB=m\angle DCE[/tex] (Congregant angles)
[tex]m\angle ACB=8x+4[/tex]
Using exterior angle theorem in triangle ABC, we get
[tex]m\angle A+m\angle C=\text{Exterior }m\angle B[/tex]
[tex]m\angle BAC+m\angle ACB=130^\circ[/tex]
[tex](3x-6)+(8x+4)=130^\circ[/tex]
[tex]11x-2=130^\circ[/tex]
Isolate the variable term x.
[tex]11x=130^\circ+2[/tex]
[tex]11x=132^\circ[/tex]
[tex]x=\dfrac{132^\circ}{11}[/tex]
[tex]x=12^\circ[/tex]
Now, the measure of angle A is:
[tex]m\angle A=3x-6[/tex]
[tex]m\angle A=3(12^\circ)-6[/tex]
[tex]m\angle A=36^\circ-6[/tex]
[tex]m\angle A=30^\circ[/tex]
Therefore, the correct option is B.
