Answer:
y=3/4x+1/4
Step-by-step explanation:
Perpendicular lines have slopes that are negative and reciprocal. If you multiply them together, the result is -1.
So, to find the slope of the new line, we can use this equation:
-4/3m=-1
multiply both sides by 3/-4
m=3/4
So the slope of the new line is 3/4
Here's the equation so far:
y=3/4x+b (b is a placeholder)
we can substitute the point (5,4) into the equation, since the line is going to pass through it.
4=3/4(5)+b
4=15/4+b
1/4=b
So the line is y=3/4x+1/4
Hope this helps!

Answer:
He would drive 536 miles in 5 hours
Step-by-step explanation:
First set up your equation:
804 = 12x
Divide 804 by 12 and get 67 = x
Since per one hour you drive 67 miles, multiply 67 by 8 and get 536.
So, he drives 536 miles in 5 hours
Answer: I think 402
Step-by-step explanation: I divided 804 to 4 and I got 201 then I added 201+201= 402 and each 4 hours he went 201 miles so if you add 201 and 201 you get 402 miles. Hope it helped!! :)
Luke went to a blackjack table at the casino. At the table, the dealer has just shuffled a standard deck of 52 cards.
Luke has had good luck at blackjack in the past, and he actually got three blackjacks with Queens in a row the last time he played. Because of this lucky run, Luke thinks that Queens are the luckiest card.
The dealer deals the first card to him. In a split second, he can see that it is a face card, but he is unsure if it is a Queen.
What is the probability of the card being a Queen, given that it is a face card? Answer choices are in a percentage format, rounded to the nearest whole number.
a) 8%
b) 4%
c) 33%
d) 77%
Answer:
c) 33%
Step-by-step explanation:
In a standard deck of cards, there are 52 cards total and of those 52, there are 12 face cards. One-third of those face cards are queens, (because there are 4 queens in a deck of cards, and [tex]\frac{4}{12}=\frac{1}{3}[/tex]). Therefore, there is a 33% chance that the card Luke holds is a queen.
Answer:
33%
Step-by-step explanation:
Got it right on the test.

Find the PERCENT of Change.
The original cost was $50 and the new cost is $200.
Answer:
300%
Step-by-step explanation:
To find percent change we need to use this formula:
[tex]change = \frac{Amount of change}{Original} * 100[/tex]
To find the amount of change we need to minus 50 from 200:
200 - 50 = 150
Now that we have the amount of change we can plug it in to the equation with the original amount (50):
[tex]change = \frac{150}{50} = 3 * 100 = 300[/tex]
Therefore, the percent of change is 300%.
I hope this helps!!

(a) Complete the table of values for the graph x + y = 6
Please help ❤️ complete the table leave the graph bit as I know how to do it
Answer:
(0,6)
(1,5)
(2,4)
(3,3)
(4,2)
Step-by-step explanation:
To solve this table first convert the equation to slope-intercept form (y=mx+b), to do this solve for y in the equation. The slope-intercept form is y=-x+6, where -1 is the slope and 6 is the y-intercept. Then from that, you can get your first point, because you know the y-intercept is 6, therefore when x equals 0 y must be 6. Next, because the slope is -1 that means the y-value decreases by 1 every time the x-value increases by 1. So to find the rest of the y-values simply subtract 1 from the previous y-value.
A bag contains 2 red marbles, 3 green marbles, and 4 blue marbles.
If we choose a marble, then another marble without putting the first one back in the blag, what is the
probability that the first marble will be green and the second will be red?
Answer:
number of green ÷ total number of marbles
times by
number of red ÷ total number of marbles left
so
(3/9) × (2/8) = (1/12)
What is the fifth term of the geometric sequence whose first three terms are 486, 162, and 54?
a. 2
b. 3
c. 4.5
d. 6
e. 9
Answer:
6
Step-by-step explanation:
an = ar^(n-1)
a = first term
n = nth term
r = common ratio
r = r2 / r1 = r3 / r2
The first 3 terms are :
486, 162, and 54
Hence,
a = 486
r = 162 / 486 = 1/3
Hence ;
a5 = 486(1/3)^5 - 1
a5 = 486(1/3)^4
a5 = 486(1 / 81)
a5 = 486 * 1 / 81
a5 = 486 / 81
a5 = 6
The 5th term of the geometric progression will be ; 6

(3,4);m=-z in point slope formula
Given:
Point = (3,4)
Slope : m = -z
To find:
The point slope formula.
Solution:
Point slope form: If a line passes through the point [tex](x_1,y_1)[/tex] and having slope m, then the point slope form of the line is
[tex]y-y_1=m(x-x_1)[/tex]
The line passing through the point (3,4) and having slope -z.
Putting [tex]x_1=3,y_1=4, m=-z[/tex], we get
[tex]y-4=-z(x-3)[/tex]
Therefore, the required point slope form is [tex]y-4=-z(x-3)[/tex].

Solve for x using the
distributive property.
2(x - 5) = 10
Answer:
x=10
Step-by-step explanation:
2x-10=10
2x=20
x=10
Answer:
x=10
Step-by-step explanation:
2(x - 5) = 10
You would first multiply 2 by x and 5
2x-10 = 10
then you would add ten to both sides
2= 20
then you would divide 2 by 20
x=10

1.25 + (- 0.75) is equal to 1.25 - 0.75.
1.25 is positive while - 0.75 is negative. So 1.25 is head toward the right while - 0.75 is head toward the left.
And when you substract them, you will get 0.5.
So the answer is C.

Dexter runs around a track at 10 laps in 20 minutes. If he ran 32 laps at that rate, how long would it take him?
Answer:
64
Step-by-step explanation:
He will run 30 laps in 60 minutes because 10 times 3 and so if you divide 20 by 10 then he runs one lap in 2 minutes so 2 times 32 is 64 so it will take him that long

At the neighborhood grocery, 55 pounds of steak cost \$20.60$20.60. How much would it cost to buy 44 pounds of steak?
Answer:
$16.48
Step-by-step explanation:
Create a proportion where x is the cost of 44 pounds of steak:
[tex]\frac{55}{20.60}[/tex] = [tex]\frac{44}{x}[/tex]
Cross multiply and solve for x:
55x = 906.4
x = 16.48
So, the cost of 44 pounds of steak is $16.48
