Find the equation of the line that is perpendicular to the given line and passes through the given point. Enter your answer in slope-intercept form (y = mx + b) with the values of m and b given as decimals, rounded to the nearest hundredth if necessary.
y = 2x ; (5, −5)
The equation is y = .
9514 1404 393
Answer:
y = -0.50x -2.50
Step-by-step explanation:
The perpendicular line will have a slope that is the opposite reciprocal of the slope of the given line:
m = -1/2
The given point can be used with this slope in the point-slope equation for a line:
y -k = m(x -h) . . . . . line with slope m through point (h, k)
y +5 = -1/2(x -5)
y = -1/2x +5/2 -5
y = -0.50x -2.50
What is the 8th term of the sequence?
1 , 3 , 6 , 10 , 15
Answer:
36
Step-by-step explanation:
Find the rule for the sequence.
The change from 1 to 3 is +2.
The change from 3 to 6 is +3.
The change from 6 to 10 is + 4.
The change from 10 to 15 is + 5
Essentially, you are adding 1 and then adding it to the current number. The next 3 numbers are:
Change of +6: 15 + 6 = 21
Change of +7: 21 + 7 = 28
Change of +8: 28 + 8 = 36
36 is your 8th term.

Which situation is best described by the graph shown?
A-JJ purchases chips for $0.75 per bag.
B-Mark buys a pack of gum for $1.50 each.
C-Paula pays $0.50 per ticket at the fair.
D-Franco purchases flowers for $3.00 each.Franco purchases flowers for $3.00 each.
Answer:
Mark buys a pack of gum for 1.50 each cause if you look at the graph 2 packs=3 and 1.50*2 is 3.00
Step-by-step explanation:
Let p represent a true statement, let q and r represent the false statements. Find the
truth value of the given compound statements.
~(pvq) ^~(p^q)
Solutions:
If p is true and q is false, then
• p ∨ q is true, and so ¬ (p ∨ q) is false (¬ stands for "negation" or "not")
• p ∧ q is false, and so ¬ (p ∧ q) is true
which means
¬ (p ∨ q) ∧ ¬ (p ∧ q)
is false.

At a carnival, the dart game costs $0.50 to play and the ring toss game costs $0.25 to play. You have $5 to spend on the two games. Write an inequality for the number of times you can play the two games.
Answer:
0.5x + 0.25y ≤ $5
Step-by-step explanation:
Let the number of times you can play dart game = x
The number of times.you can play ring toss games = y
At a carnival, the dart game costs $0.50 to play and the ring toss game costs $0.25 to play. You have $5 to spend on the two games.
Write an inequality for the number of times you can play the two games.
Hence, the inequality =
0.5x + 0.25y ≤ $5
it takes 15 cups of water to fill 1/3 pail. How much water is needed to fill 1 pail?
Answer:
45 cups
Step-by-step explanation:
15x3 because there are 3 cups and 15 is one of the cups so 15x3=45
Answer:
45 Cups
Step-by-step explanation:
Use a proportion with cups in the numerator and pail in the denominator .
15/(1/3) = X/ 1
15 ÷1\3 = 15 x 3 =45 cups

Answer:
x=8
Step-by-step explanation:
The length of a given rectangle is six more than twice its width. Write a fully simplified expression to represent its perimeter.
Answer:
[tex]Perimeter = 12 + 6y[/tex]
Step-by-step explanation:
Represent the length with x and width with y
By analysis, we have:
Length = 6 + 2 times the width.
Mathematically, the expression is:
[tex]x = 6 + 2 * y[/tex]
[tex]x = 6 + 2 y[/tex]
Required: Determine the perimeter
Perimeter of a rectangle is calculated as:
[tex]Perimeter = 2 * (Length + Width)[/tex]
Substitute x for length and y for width
[tex]Perimeter = 2 * (x + y)[/tex]
Substitute 6 + 2y for x
[tex]Perimeter = 2 * (6 + 2y + y)[/tex]
[tex]Perimeter = 2 * (6 + 3y)[/tex]
Open bracket
[tex]Perimeter = 2 * 6 + 2 * 3y[/tex]
[tex]Perimeter = 12 + 6y[/tex]

You want to buy some beans. A 7-ounce package costs $2.45.A 15-0unce package costs S4.95. A
26-ounce package costs $8.84. Which package is the best buy
TheM-Ounce package of beans IS the best
Answer:
15-ounce package is the best buy.
Step-by-step explanation:
In order to find the best-buy we have to calculate the price per ounce.
So,
For 7-ounce package:
Price =2.45$
Unit price for 7-ounce:
[tex]\frac{2.45}{7} = 0.35\$[/tex]
For 15-ounce Package:
Price: $4.95
Unit price for 15-ounce:
[tex]\frac{4.95}{15} = 0.33\$[/tex]
For 26-ounce Package:
Price: $8.84
Unit price for 26-ounce:
[tex]\frac{8.84}{26} = 0.34\$[/tex]
As we can see that the least unit price is for 15 ounce pack i.e. 0.33 per ounce so,
15-ounce package is the best buy.

i need help with pre-cal, please!
Answer:
b ≈ 4.2
Step-by-step explanation:
Using the tangent ratio in the right triangle, that is
tan50° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{5}{b}[/tex] ( multiply both sides by b )
b × tan50° = 5 ( divide both sides by tan50° )
b = [tex]\frac{5}{tan50}[/tex] ≈ 4.2 ( to the nearest tenth )
At a bakery, cupcakes cost $4 each and brownies cost $3 each. Which equation represents the total cost, T, of c cupcakes and b brownies?
Answer: 3b + 4c = T
Since brownies are three dollars and cupcakes are four, we simply do the amount of items bought multiplied by three or four.

Jonathan is four times Maria's age. In 3 years, he will be three times as old as Maria is then. How old is Maria now?
Answer: 6 years
Step-by-step explanation:
Let Maria's age be x
Jonathan is four times Maria's age. This means that Jonathan age = 4x
In 3 years, he will be three times as old as Maria is then. This can be written as:
4x + 3 = 3(x + 3)
4x + 3 = 3x + 9
4x - 3x = 9 - 3
x = 6
Maria is 6 years
