Answer:
Domain: {-2,6,18}
Range: {-1,2,3}
This relation is not a function.
Step-by-step explanation:
The domain is all of the x values given listed in order from least to greatest and not repeating any numbers. The range is the same thing, but with the y values given. This is not a function because multiple ordered pairs have more than one output for the input. Let's take -2 in these ordered pairs. It has two different outputs, 3 and 2. Because of this, it is not a function.

Find the slope of the line that passes through (10, 63) and (94, -7).
Answer:
The slope is [tex]-\frac{5}{6}[/tex]
Step-by-step explanation:
Hi there!
We are given two points: (10, 63) and (94, -7)
We want to find the slope that passes through these lines
We can use the slope formula to find it
The formula for slope calculated from two points is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex], where [tex](x_1, y_1)[/tex] and [tex](x_2, y_2)[/tex] are points
We have everything needed to find the slope, let's just label their values to avoid confusion:
[tex]x_1=10\\y_1=63\\x_2=94\\y_2=-7[/tex]
Now substitute these values into the formula:
m=[tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
m=[tex]\frac{-7-63}{94-10}[/tex]
Subtract the numbers:
m=[tex]\frac{-70}{84}[/tex]
Divide:
m=[tex]-\frac{5}{6}[/tex]
The slope of the line is [tex]-\frac{5}{6}[/tex]

a submarine descends 480 ft and 24 seconds the submarines elevation changes at a constant rate what is the elevation change of the submarine after 8 Seconds
Answer:
The submarine would be 900 below the ocean surface after 12 minutes assuming it started its descent at the surface of the ocean.
Step-by-step explanation:
The formula for distance traveled (in this case the distance a submarine descends) over a period of time is:
d
=
r
⋅
t
where
d
is the distance traveled (or descended),
r
is the rate of travel and
t
is the time.
In this problem we are told the rate,
r
is 75 feet per minute. And, we are told the time,
t
, to calculate for which is 12 minutes.
What is the value of x and y in the following figure?
Answer:
Step-by-step explanation:
x = 75°
75° + 75° + a = 180°
a + 150° = 180°
a = 180° - 150°
a = 30°
y + 30° = 90°
y = 90° - 30°
y = 60°
I hope I've helped you
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
The required values are ~
[tex] \boxed{x = 75 \degree}[/tex]
and
[tex] \boxed{y = 60 \degree}[/tex]
[tex] \large \boxed{ \mathfrak{Step\:\: By\:\:Step\:\:Explanation}}[/tex]
As it's shown in the figure, the sides opposite to x and Angle 75° are equal. So the corresponding Angles are also equal to one another.
that is ~
[tex]x = 75 \degree[/tex]I have taken an angle and marked it as " m " in the attachment.
So, according to Angle sum property of a triangle,
[tex]m + x + 75 \degree = 180 \degree[/tex][tex]m + 75 \degree+ 75 \degree= 180 \degree[/tex][tex]m + 150 \degree= 180 [/tex][tex]m = 180 \degree - 150 \degree[/tex][tex]m = 30 \degree[/tex]now, it's given that the sum of Angle y and Angle m is 90°
hence,
[tex]m + y = 90 \degree[/tex][tex] 30 \degree + y = 90 \degree[/tex][tex]y = 90 \degree - 30 \degree[/tex][tex]y = 60 \degree[/tex]Solve the system by substitution y=5x y=-x+30
Answer:
Step-by-step explanation:
y = 5x
y = x + 30
Substitute y = 5x in second equation:
5x = x+ 30
4x = 30
x = 7.5.
and y = 5*7.5 = 37.5.
Solve for y
3x + 2y = 9
Answer:
y = -[tex]\frac{3}{2}[/tex]x + 4[tex]\frac{1}{2}[/tex]
Step-by-step explanation:
Given: 3x + 2y = 9
Get y alone: 2y = -3x + 9
Get y alone part 2: y = -[tex]\frac{3}{2}[/tex]x + 4[tex]\frac{1}{2}[/tex]
Unless we have an x value this is as far as we can solve. Have a nice day! :D

Write 8x³y³ as the power of a product.
Answer:
(2xy)³
Step-by-step explanation:
According to the Power Rule of Exponents:
[tex](ab})^{m} = a^{m}b^{m}[/tex]
We can apply the Power Rule of Exponents to the given exponential expression, 8x³y³, by taking the smallest factor that when cubed (or raised to an exponent of 3), will produce the same results as the original exponential expression.
8 is a perfect cube of 2: ⇒ 2 × 2 × 2 = 2³ = 8
The cube of x is x³: ⇒ x × x × x = x³
The cube of y is y³ ⇒ y × y × y = y³
Hence, we can take the least common factors, (2xy) and raise them to the third power:
(2xy)³ = 2³x³y³ = 8x³y³
Therefore, the correct answer is: (2xy)³
[tex]\\ \sf\longmapsto 8x^3y^3[/tex]
8=2^3x^3=(x)^3y^3=(y)^3We know the rule of exponents
[tex]\boxed{\sf (ab)^m=a^mb^m}[/tex]
Now
[tex]\\ \sf\longmapsto 8x^3y^3[/tex]
[tex]\\ \sf\longmapsto 2^3x^3y^3[/tex]
[tex]\\ \sf\longmapsto (2xy)^3[/tex]
[tex]\\ \sf\longmapsto (2xy)(2xy)(2xy)[/tex]

Answer:
1: a. x=120, b. x=19, 2: mOPR=137, mSRQ=140, mPQT=83
Step-by-step explanation:
1.
a. since x is an exterior angle, we know x is the sum of the other 2 interior angles. the box in the corner means that angle is a right angle, or 90 degree angle. so x = 90 + 30, s=120
b. again, 103 is an exterior angle so 103 = 47-x +2x+38. simplify to get 103 = x+84, so x=19
2.
OPR is an exterior angle so mOPR = mPQR + mPRQ, or 2y+15 = 97 + y-21. simplify and solve for y to get y=61. plug this into 2y+15 to get mOPR = 137.
because SRQ is an exterior angle, it equals RPQ + PQR. first we need to find RPQ. since PQR is a triangle, PQR + PRQ + RPQ = 180. PRQ = y-21 = 40. so RPQ=180-97-40 = 43. so SRQ = 43+97 = 140. (you could also use the fact that PRQ + SRQ = 180)
the exterior angles added up together = 360, so OPR + SRQ + PQT = 360. plug in the known values to get PQT = 360 - 137 - 140 = 83
[tex]s = \frac{w - 10e}{m} [/tex]
I'm trying to solve for w
9514 1404 393
Answer:
w = ms +10e
Step-by-step explanation:
The basic idea is to undo what is done to w. Here, 10e is subtracted, and the difference is divided by m. We undo these in reverse order. To undo the division, we multiply by m. To undo the subtraction, we add the quantity that was subtracted. Any operation that we perform must be done to both sides of the equation.
[tex]s = \dfrac{w - 10e}{m}\qquad\text{given}\\\\ms=w-10e\qquad\text{multiply by $m$}\\\\ms+10e=w\qquad\text{add $10e$}[/tex]
Usually, you want to write that with w on the left:
w = ms +10e

Which linear equation represents a line with a slope of 94 and a y-intercept of 0?
1). y = 9/4y
2). y = x + 9/4
3). x = 9/4x
4). y=9/4x
Answer:
4)
Step-by-step explanation:
I think that you meant slope of 9/4. Number 4 would be correct because slope intercept form would be y=mx+b, where m is the slope and b is y intercept. Since b=0, you don't have to add anything, so it would just be y=9/4x
Answer:
4) [tex]y=\frac{9}{4}x[/tex]
Step-by-step explanation:
This is a linear equation in slope-intercept form:
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept.
1) [tex]y=\frac{9}{4}y[/tex] --- this is just a false equation that cannot be a line.
2) [tex]y=x+\frac{9}{4}[/tex] --- this is a line with a slope of 1 and a y-intercept of 9/4
3) [tex]x=\frac{9}{4}x[/tex] --- this is also false
4) [tex]y=\frac{9}{4}x[/tex] --- this is a line with a slope of 9/4 and a y-intercept of 0.

When you see equations with parenthesis, that means you must do distributive property. So, whatever number is outside of the parenthesis, you multiply it by all the number inside of the parenthsis.
Answer:
6x² + 48x + 42
Step-by-step explanation:
2(x + 7) 3(x + 1) ← multiply the integers
= 6(x + 7)(x + 1) ← expand factors using FOIL
= 6(x² + 8x + 7) ← distribute parenthesis by 6
= 6x² + 48x + 42

Taxable income is a person's gross income minus
O A. hours worked
O B. allowable deductions
C. profits
O D. revenue
Taxable income is a person's gross income minus allowable deductions.
The correct option is B.
As, Any gross income that is used to determine how much tax you owe is referred to as taxable income.
This is equal to your AGI less the total of either your itemized deductions or the standard deduction, whichever is greater, and, if available, the qualifying business income deduction.
So, Taxable income is a person's gross income minus allowable deductions.
Thus, the ideal solution is B.
