Step-by-step explanation:
the domain is the set or interval of all valid x values.
the range is the set or interval of all valid y values.
1.
domain = {-1, 2, 5}
range = {0, 2, 3, 7}
function : no, because x = -1 has 2 different y values assigned (7 and 2). that violates the definition of a function.
2.
domain = {-3, -2, -1, 1, 4}
range = {-5, -1, 0, 2}
function : yes. every x bake has exactly one y value assigned.
3.
domain = {4, 6, 7}
range = {-1, 2, 3, 5}
function : no, because x = 4 has 2 different y values assigned (2 and 5).
4.
domain = [-3, 3) "3" is not included, hence the empty dot
range = [-4, 5]
function : yes
5.
domain = (-infinity, +infinity) "infinity" is not a possible value, so the limits are not included.
range = [-1, 2]
function : yes
6.
domain = [-2, +infinity)
range = (-infinity, +infinity)
function : no. except for x = -2 all x values have 2 different y values assigned.

The difference between two trinomials is 5x2 + 11x − 16. If one of the trinomials is 3x2 − 2x + 7, then which expression could be the other trinomial?
Applying the difference, it is found that the other trinomial could be given by: 8x² + 9x - 9.
What are the trinomials?We are working with second degree trinomials, hence:
One is 3x² - 2x + 7.The other is ax² + bx + c.The difference is 5x² + 11x - 16.Hence:
ax² + bx + c - (3x² - 2x + 7) = 5x² + 11x - 16.
(a - 3)x² + (b + 2)x + c - 7 = 5x² + 11x - 16.
Then:
a - 3 = 5 -> a = 8.b + 2 = 11 -> b = 9.c - 7 = -16 -> c = -9Then, the trinomial is:
8x² + 9x - 9.

Answer: <1 = 26°
Step-by-step explanation:
given that:
• <ABD = 66°
• <2 = 14° + <1 (since ''more than' means we add)
• Find <1
Since it is obvious that <ABD is a sum of <1 and <2:
⇒ <ABD = <1 + <2
now we know that <2 is 14° more than <1 and that <ABD = 66°
⇒ 66° = <1 + (14° + <1)
⇒ 66° = <1 + 14° + <1
⇒ <1 = (66° - 14°) ÷ 2
⇒ <1 = 26° ...Answer...

Statistics from the past ten years predict that the chance of rain on any single day in April in Asha’s hometown is 41%. If Asha’s birthday is April 10, what is the chance of it not raining on Asha’s birthday?
Answer:
59% chance
Step-by-step explanation:
Statistics from the past ten years predict that the chance of rain on any single day in April in Asha’s hometown is 41%. If Asha’s birthday is April 10, what is the chance of it not raining on Asha’s birthday?
Asha's birthday in in April. The chance of rain on any single day in April is 41%. So, there is a 41% chance of rain.
But, that's not what the problem is asking for. The problem is asking for the chance of not raining. To solve for this, we use simple algebra.
100%(all of the time) - 41%(how much it happens) = 59%
The 59% is the chance of it not raining on Asha's birthday.
Hope this helps! Happy birthday, Asha!

Answer:
x ≤ 1/2
Step-by-step explanation:
Domain: input values (x-values)
We cannot take a square root of a negative number, therefore
3 - 6x ≥ 0
Solving the inequality:
⇒ 3 - 6x ≥ 0
⇒ 3 ≥ 6x
⇒ 1/2 ≥ x
⇒ x ≤ 1/2
Therefore, the domain is x ≤ 1/2

sin-¹ (sin 17°) = [ ? ]°
The value of sin⁻¹ (sin 17°) is 17° or 17 degree after applying the trigonometric identity sin⁻¹ (sinx) = x
What is trigonometry?Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.
We have:
= sin⁻¹ (sin 17°)
The above expression represents an angle.
Let's suppose the angle is x and sin of x is sinx
sinx is a ratio of side opposite to the angle to hypotenuse.
If we take sin inverse of sinx we get an angle of x.
sin⁻¹ (sinx) = x
sin⁻¹ (sin 17°) = 17 degree
Thus, the value of sin⁻¹ (sin 17°) is 17° or 17 degree after applying the trigonometric identity sin⁻¹ (sinx) = x

x(x-5)-9(x-5)
(x-9)(x-5)
Answer:
(x-9)(x-5)
Step-by-step explanation:
To factor this expression, you need to find two values that have a sum of -14 and also have a product of 45. The values -5 and -9 meet these requirements and become the constants in the two factors of the expression,
x2 − 14x + 45 = (x − 9)(x − 5).

Parallel lines have equal slope so
M1-M2=0Lets check
M1=3/4M2=12/16=3/4Now
M1-M23/4-3/40Lines are parallel
Answer:
The two lines are parallel
Step-by-step explanation:
If two lines are parallel, they have the same slope.
If two lines are perpendicular, the slopes will be negative reciprocals (the product of the slopes will be -1).
Given slopes:
[tex]\sf m_1=\dfrac{3}{4}[/tex]
[tex]\sf m_2=\dfrac{12}{16}[/tex]
Reduce m₂ to its simplest form by dividing the numerator and denominator by the largest common factor:
[tex]\sf m_2=\dfrac{12 \div 4}{16\div 4}=\dfrac{3}{4}[/tex]
Therefore,
[tex]\sf as \quad \dfrac{3}{4}=\dfrac{3}{4} \implies m_1=m_2 \quad[/tex]
As the given slopes are the same, the two lines are parallel.

The length of the chord AC in the circle is 24 units.
What are Chords?Chords are line segment joining any two sides of a circumference of a circle.
The radius of a circle is half of diameter of the circle.
Therefore, a radius or diameter that is perpendicular to a chord divides the chord into two equal parts and vice versa.
Hence, the radius that runs through M is perpendicular to the chord AC. Therefore, the chord AC is divided into two halves namely AM and MC.
Hence,
AC = AM + MC
AC = 12 + 12
AC = 24 units

What is an equation of the line that passes through the point (-7,-6) and is parallel to the line x-y=7?
Answer:
y = x + 1
Step-by-step explanation:
Step 1: Find the slope.
Parallel lines have the same slope. That means that the line we are seeking is going to have the same slope as line x - y = 7.
To find the slope of the line x - y = 7 let's change it to the slope-intercept form.
Slope-Intercept Form
y = mx + b
m ... slope
b ... y-intercept
Let's change the equation of the parallel line to slope-intercept form (isolate y).
x - y = 7
Add y on both sides.
x - y + y = 7 + y
x = 7 + y
Subtract 7 on both sides.
x - 7 = 7 + y - 7
x - 7 = y
y = x - 7
Let's read the slope from the equation.
Instead of y = x - 7 we can write y = 1x -7.
Now it's obvious that m (slope) is 1.
m = 1
So far, our equation of the line is:
y = 1x + b
which is te same as
y = x + b
Step 2: Find y-intercept.
To find out y-intercept (b), we substitiute the point (-7, -6) in the equation. Points are in form (x, y) so -7 is x and -6 is y.
y = x + b
-6 = -7 + b
Solve for b.
1 = b
Step 3: Substitute slope and y-intercept in general formula for slope-intercept form of the line.
Now substitute m and b in slope-intercept form y = mx + b.
m = 1
b = 1
Equation of the line:
y = x + 1
Line / is parallel to line m. The slope of line / is 2/7. What is the slope of line M ?

helpp
The total amount Sam will pay in all will be $2,400,000
Simple interest
From the question, we are to determine the interest Sam pays in all
Using the simple interest formula,
I = PRT
From the given information,
P = $2,000,000
R = 5% = 0.05
T = 4
Putting the parameters into the formula,
I = $2000000 × 0.05 × 4
I = $400000
The interest Sam will pay is $400,000
The total amount Sam will pay in all will be $2,000,000 + $400,000
= $2,400,000
