Question 1
Which point could be removed in order to make the relation a function?
{(-4,3), (-5, 6), (1, 0),(-4,5), (9,5), (0, -7)}
Answer:
Either (-4, 3) or (-4, 5).
Step-by-step explanation:
A function is a relation when each input has exactly one output. The inputs must not repeat in a function.
In the relation given, the input '-4' repeats.
{(-4,3), (-5, 6), (1, 0),(-4,5), (9,5), (0, -7)}
If we remove either (-4, 3) or (-4, 5), it would make the relation a function.

Answer: 45
Step-by-step explanation:
which of the following relations or graphs are functions
Answer:
Step-by-step explanation:
The functions are:
(a), (c), (d), (e).
Relations may or may not represent a function.
The relations that are functions are (a), (c), (d), (e)
Graph (a) shows a linear relationship, and all linear relations are functions.
Graph (b) fails the vertical line test, because an x value corresponds to multiple y values; so graph (b) is not a function.
Similarly, ordered pair (f) is not a function because an x value corresponds to multiple y values
Other relations (c), (d) and (e) are functions

what does congruent mean in geomatry?
Answer:
Congruent means same shape and same size. So congruent has to do with comparing two figures, and equivalent means two expressions are equal. So to say two line segments are congruent relates to the measures of the two lines are equal. Comment on David Severin's post “Congruent means same shape and same size.

how does the percent equation relate to proportional quantities?
Answer:
Step-by-step explanation:
Use cross product to determine if the two ratios form a proportion. Here we can see that 2/16 and 5/40 are proportions since their cross products are equal. Percent means hundredths or per hundred and is written with the symbol, %. Percent is a ratio were we compare numbers to 100 which means that 1% is 1/100.
Answer:
The proportion is a general case of percentage.
Step-by-step explanation:
Proportion is a general case of percentage.
It describes how much of the total a particular sample is.
For example, if a pie contains eight slices and you have five, the proportion is 5/8.
You have a total of five out of eight.
A percent (the number of parts out of 100) is a special case of proportion where the denominator (“whole”) equals 100 parts.
I suspect that percentages were created to allow a normalized comparison of proportions when the total number of parts was not the same.
Imagine a small pizza with 6 slices and a large pizza with 8 slices.
If Tom got 4 from the first and Ram got 5 from the second, it is not immediately clear who got more from the second.
Converting 4/6 and 5/8 to percentages (66.7 and 62.5) allows you to see when the denominator equals who got relatively "more".
Furthermore, I suspect that 100 was used because we live in a 10-base world (we have 10 fingers, which makes it natural).
4x + (-3) = 5x + 3?????
Hi there! :)
[tex]\large\boxed{x = -6}[/tex]
Solve for x:
4x + (-3) = 5x + 3
Adding a negative number is simply subtracting, therefore:
4x - 3 = 5x + 3
Subtract 4x from both sides:
4x - 4x - 3 = 5x - 4x + 3
-3 = x + 3
Subtract 3 from both sides:
-3 - 3 = x + 3 - 3
-6 = x

A line passes through (-1, 3) and (p, 7) and has a slope of -4/3 Find the value of p.
slope= (x2-xl)(y2-y1)
Answer:
Step-by-step explanation:
y - 3 = - [tex]\frac{4}{3}[/tex] ( x + 1 )
y = - [tex]\frac{4}{3}[/tex] x - [tex]\frac{4}{3}[/tex] + 3
y = - [tex]\frac{4}{3}[/tex] x + [tex]\frac{5}{3}[/tex]
7 = - [tex]\frac{4}{3}[/tex] p + [tex]\frac{5}{3}[/tex]
[tex]\frac{4}{3}[/tex] p = - 7 + [tex]\frac{5}{3}[/tex]
p = ( - [tex]\frac{16}{3}[/tex] ) × [tex]\frac{3}{4}[/tex] = - 4
List the first 4 terms of a geometric sequence with a first term of 2 and a common ratio of 5.
I have no clue even where to start. The question after that is the same, except the first term is 4 and the common ratio is 4.
Answer:
pohujnkmhugyfdtr
Step-by-step explanation:
The first 4 terms of the geometric sequence with a first term of 2 and a common ratio of 5 are 2, 10, 50, 250
using the geometric sequence formula,
aₙ = arⁿ⁻¹where
a = first term = 2
r = common ratio = 5
let find the remaining 3 terms
The 2nd term can be found below
a₂ = 2 × 5²⁻¹ = 2 × 5 = 10The 3rd term can be found below
a₃ = 2 × 5³⁻¹ = 2 × 25 = 50The 4th term can be found as follows
aₙ = 2 × 5⁴⁻¹ = 2 × 125 = 250Therefore, the first 4 terms are 2, 10, 50, 250.

Answer:
A=2wl+2lh+2hw
A=2(x+7)(x+3)+2(x+3)(x-1)+2(x-1)(x+7)
A=2(x^2+7x+3x+21)+2(x^2-x+3x-3)+2(x^2+7x-x-7)
A=2(x^2+10x+21)+2(x^2-2x-3)+2(x^2+6x-7)
Answer:
6x²+36x+22
Step-by-step explanation:
Surface Area = 2(wl + hl + wh)
Length = (x+3)
Width = (x+7)
Height = (x-1)
Surface Area = 2((x+7)(x+3) + (x-1)(x+3) + (x+7)(x-1))
Then simplify
2((x+7)(x+3)+(x−1)(x+3)+(x+7)(x−1))
=(2)((x+7)(x+3)+(x−1)(x+3)+(x+7)(x−1))
=(2)((x+7)(x+3))+(2)((x−1)(x+3))+(2)((x+7)(x−1))
=2x²+20x+42+2x²+4x−6+2x²+12x−14

Explanation:
Given the two baselengths, and the perpendicular height of the trapezoid, you can actually find the perimeter through the pythangorean theorem because the perpendicular height or height that forms a right or 90 degree angle makes a right triangle(2 be exact because this is an isoceles trapezoid which has two adjacent right triangles).
This is true of the trapezoid is icosceles.

Find the value of b. Then find the angle measures of the pentagon.
Answer:
b = 90
Step-by-step explanation:
Sum the interior angles of the pentagon and equate to 540
Starting from the top and going clockwise
b + b + 45 + 90 + 2b - 90 + [tex]\frac{3}{2}[/tex] b = 540 ← simplify left side
[tex]\frac{11}{2}[/tex] b + 45 = 540 ( multiply through by 2 to clear the fraction )
11b + 90 = 1080 ( subtract 90 from both sides )
11b = 990 ( divide both sides by 11 )
b = 90
Thus
b + 45 = 90 + 45 = 135
2b - 90 = 2(90) - 90 = 180 - 90 = 90
[tex]\frac{3}{2}[/tex] b = [tex]\frac{3}{2}[/tex] × 90 = 135
The angle measure from the top clockwise are
90°, 135°, 90°, 90°, 135°

Of two consecutive integers, twice the smaller is four less than the greater. Find the integers. Provide and equation if you don't have a direct answer.
Answer:
The smaller integer is -3 and the greater integer is -2
Step-by-step explanation:
Equations
Let's call
x = the smaller integer
x + 1 = greater consecutive integer
The relationship between them is that twice the smaller is four less than the greater:
2x = x + 1 - 4
Subtracting x:
x = 1 - 4
Operating:
x = -3
x + 1 = -2
The smaller integer is -3 and the greater integer is -2
