What are the intercepts of y = x + 5 (Remember that intercepts mean both x-intercept & y-intercept.) a) (5, 0) & ( 0, 5) b) ( -5, 0) & (0 , 5) c) (5, 0 ) & (0, -5) d) (-5, 0 ) & ( 0, -5)
Greetings from Brasil...
We have to remember 2 details:
→ When X = 0, the function intersects the Y axis
→ When Y = 0, the function intersects the X axis
So
1: X = 0
Y = X + 5
Y = 0 + 5
Y = 5
X = 0 and Y = 5 ⇔ (0; 5)
2: Y = 0
Y = X + 5
0 = X + 5
X = - 5
Y = 0 and X = - 5 ⇔ (- 5; 0)
Then the point at which the graph intersects the X and Y axis will be
(0; 5) and (- 5; 0)
If speed varies inversely as the time it takes to drive and Kris takes 5 hours driving at 55 mph, what speed will Martin need to
drive if he wants to take 5 hours?
O 50 mph
52.4 mph
O 60.5 mph
O 51.5 mph
Answer:
55mph . None of the options are correct
Step-by-step explanation:
If the speed varies inversely as the time it takes to drive, then v ∝ 1/t. where;
v is the speed
t is the time taken
Hence;
v = k/t with k being the constant of proportionality.
Since it takes Kris 5 hours when driving at 55 mph, we will substitute v = 55mph and t = 5 hours. into the equation above to get the value of k as shown:
55 = k/5
Cross multiply
k = 55*5
k = 275
Hence, to calculate the speed it will Martin to drive for 5 hours, we will substitute k = 275 and t = 5 into the original equation v = k/t as shownl
v = 275/5
v = 55 mph
Hence, we can conclude that Martin will also need to drive at a speed of 55mph if he wants to take 5hours.

Let p: x = 4 Let q: y = -2 Which represents if x = 4, then y = -2. Please hurry
Answer:
p: x = 4
q: y = -2
If p happens then q will also happen
Step-by-step explanation:
Given two propositions, we want to rearrange them in a conditional statement.
The correct answer is:
p → q
First, a conditional statement is something of the form:
If [Hypothesis] then [Conclusion]
So, if the first part is true, then the second part must be true.
Now, here we have two propositions:
p: "x = 4"
q: "y = -2"
We want to write:
"if x = 4, then y = -2"
this is just written as: "p implies q" or:
p → q
Where "→" means "then", and the initial "if" is tacit.

Janet wants to calculate the time it takes to earn a certain amount of interest on a principal amount in an investment with simple interest. What equation can she use?
Answer:
T = 100I/PRStep-by-step explanation:
Given the amount invested for a particular period of time at an interest rate, the equation that can model the Interest achieved on investment is expressed using the simple interest formula as shown;
Simple Interest = PRT/100 where;
P is the principal (amount invested)
R is the rate (in %)
T is the time (in years)
From the equation I = PRT/100, we need to express tht time T as a function of the rest of the variable as shown;
I = PRT/100
cross multiply
100I = PRT
Divide both sides by PR
100I/PR = PRT/PR
100I/PR = T
Hence the the time it takes to earn a certain amount of interest on a principal amount in an investment with simple interest is expressed as
T = 100I/PR

What is the solution to the division problem? Enter numbers in the boxes to complete the problem.
Answer:52
Step-by-step explanation:
How many times can 8 go into 4. 0 so how many times can 8 go into 41 without going over 41.
8 x 5 = 40
41 - 40 = 1
bring down the next number which is 6
16 how many times can 8 go into 16, 2.
8 x 2 = 16
16 - 16 = 0
Start with the first number inside the division bracket (4). Because 8 can't go into 4, include the second number in the division bracket (1). Because 8 can go into 41 with a whole number, put a 5 above the bracket and subtract the value of 5*8 from 41. You should get 1. Then, bring down the 6 to form 16. Because 8 can evenly go into 16 twice, put a 2 next to the 5 above the bracket. Multiply 2*8 and subtract the value from 16.

Determine the value of x shown in the diagram
Answer:
x = 145
Step-by-step explanation:
If we look at the right triangle with sides of 24 and 30, we can find the missing leg using the Pythagorean Theorem. If we look carefully, we notice that 18:24:30 is basically the 3:4:5 Pythagorean Triple multiplied by 6, so the missing side is 18. If we look at the right triangle with sides of x and 24, we can find the missing side by calculating 161 - 18 = 143. Using the Pythagorean Theorem, we know that 143² + 24² = x² so x = 145.

The period T(in seconds) of a pendulum is given by T=2 pi root L over 32 where the L stands for Length(in feet) of the pendulum. If `pi 3.14, and the period is 3.14 seconds, what is the length?
Answer:
8 feet = L
Step-by-step explanation:
The period T(in seconds) of a pendulum is given by T=2 pi root L over 32
T= 2π√(L/32)
where the L stands for Length(in feet) of the pendulum.
If π= 3.14, and the period is 3.14 seconds
Length will be
T= 2π√(L/32)
3.14= 2*(3.14)√(L/32)
(3.14/3.14)/2= √(L/32)
(1/2)²= L/32
1/4 = L/32
32/4= L

What is the probability of choosing a card from a deck of cards that is a club or a ten? Is this event mutually
exclusive or inclusive?
A. Inclusive
B. Exclusive
A. 5/16
B. 4/13
C. 1/4
D. 7/16
Answer:
Hey there!
There are 13 clubs in a deck of cards.
There are 4 tens.
However, the tens overlap with the clubs, so there are 16 cards to choose.
16/52=4/13
Let me know if this helps :)
The events are mutually inclusive. Option B is correct because the required probability is [tex]\dfrac{4}{13}[/tex].
Important information:
A card is selected randomly from a deck of cards.We need to find the probability that the card is a club or a ten.Probability:A deck of cards has total 52 cards, which includes 4 suits and each suit has 13 cards. If S be the sample space, then n(S) = 52.
Let A be the event that the card is a club card and B be the event that it is a ten card.
The number of club cards is 13. So, n(A) = 13.
There are 4 cards of 10. So, n(B) = 4.
One ten card is of club. So, [tex]n(A\cap B)=1[/tex].
Since [tex]n(A\cap B)=1\neq 0[/tex], therefore the events are mutually inclusive.
The number of club or a ten card is:
[tex]n(A\cup B)=n(A)+n(B)-n(A\cap B)[/tex]
[tex]n(A\cup B)=13+4-1[/tex]
[tex]n(A\cup B)=16[/tex]
Now,
[tex]P(A\cup B)=\dfrac{n(A\cup B)}{n(S)}[/tex]
[tex]P(A\cup B)=\dfrac{16}{52}[/tex]
[tex]P(A\cup B)=\dfrac{4}{13}[/tex]
Therefore, the probability of choosing a card from a deck of cards that is a club or a ten is [tex]\dfrac{4}{13}[/tex]. Hence, option B is correct.

l = 10+2w
48 = (10 + 2w)w
48 = 10w + 2w² | : 2
24 = 5w + w²
w² + 5w - 24 = 0
w² + 8w - 3w - 24 = 0
w(w + 8) - 3(w + 8) = 0
(w - 3)(w + 8) = 0
w - 3 = 0 => w = 3 feet
w + 8 = 0 => w = - 8 ∉ N
l = 10 + 2w
l = 10 + 6
l = 16 feet

One exterior angle of a regular pentagon has a measure of (2x)”. What is the value of x?
O x = 18
O x = 20
O x= 30
O x= 36
Answer:
x = 36°
Step-by-step explanation:
The sum of the exterior angles of a pentagon is always 360°. Since the pentagon is regular, meaning that all of its sides and interior angles are congruent, we know that all of the exterior angles are also congruent. Since a pentagon has 5 sides, we know that there are 5 congruent exterior angles, therefore:
5 * 2x = 360
10x = 360
x = 36°
The value of x in the Pentagon is 36.
Option D is the correct answer.
What is a Pentagon?A pentagon is a polygon that has five sides and five angles.
The sides and angles of a pentagon are not all equal unless it is a regular pentagon.
A regular pentagon has five equal sides and five equal angles.
We have,
The sum of the exterior angles of any polygon is 360 degrees.
Since a regular pentagon has 5 sides, the sum of its exterior angles is 360 degrees.
Each exterior angle of a regular pentagon has a measure of:
= 360 degrees / 5
= 72 degrees
We are given that one exterior angle of the pentagon has a measure of (2x) degrees.
2x = 72
Solving for x.
x = 36
Therefore,
The value of x is 36, and the measure of the given exterior angle.
= (2x)
= 72 degrees.
Thus,
The value of x is 36.

Which is the correct pair?
Answer: D
Step-by-step explanation:
Since we are given that the x value is -1, we can eliminate A and C because the -1 is in the y coordinate.
To find the proper y value, we plug x into the equation.
y=-2x+5 [plug in x=-1]
y=-2(-1)+5 [multiply -2 and -1]
y=2+5 [add 2 and 5]
y=7
Now that we have the y value, we know the coordinate (-1,7) which makes D the correct answer.
