What is an equation of the line that passes through the point (6,1) and is
perpendicular to the line 2x + 3y 18?
Answer:
y - 1 = 3/2(x - 6)
Step-by-step explanation:
First, we need to find the slope of the given equation. Without a graph, the easiest way to do this is by isolating y.
2x + 3y = 18
3y = -2x + 18 (Subtract 2x from both sides)
y = -2/3x + 6 (Divide both sides by 3)
The slope is -2/3. Perpendicular lines have opposite reciprocal slopes, so a line perpendicular to this one would need to have a slope of 3/2. We're given a point for this line, so we can write the equation for it in point-slope form.
Point-Slope Form: [tex]y - y_{1}=m (x-x_{1})[/tex]
y - 1 = 3/2(x - 6)
If necessary, this can also be written in slope-intercept form by solving for y.
To prepare for a party, Jada poured 0.45 liter of juice into each of several cups. Altogether she poured 9 liters of juice into the cups.
Answer: 20 cups
Step-by-step explanation:
Question would like to know the number of cups that Jada poured juice into.
If each cup got 0.45 litres, the number of cups that Jada poured drinks into would be the total amount of juice poured divided by the quantity per cup:
= Total juice poured / Quantity per cup
= 9 litres/ 0.45 litres per cup
= 20 cups

y2 = - 4
y1 = - 8
x2 = - 3
x1 = - 2
==========
Equation
m = (y2 - y1) / (x2 - x1)
m = (-4 - - 8) / (-3 - - 2)
m = 4 / - 1
m = - 4
Answer:
(1, -4)
Step-by-step explanation:
(-3, -4) >> (x1, y1)
(-2, -8) >> (x2, y2)
(y2 - y1) -8 - (-4) = -4
----------- >>>
(x2 - x1) -2 - (-3) = 1
x always goes first in a coordinate, so

Decrease £843 by 91% rounded to 2 DP
Answer:
Percent (%)' means 'out of one hundred':
p% = p 'out of one hundred',
p% is read p 'percent',
p% = p/100 = p ÷ 100.
91% = 91/100 = 91 ÷ 100 = 0.91.
100% = 100/100 = 100 ÷ 100 = 1.
Decrease number by 91% of its value.
Percentage decrease = 91% × 843
New value = 843 - Percentage decrease
Calculate the New Value
New value =
843 - Percentage decrease =
843 - (91% × 843) =
843 - 91% × 843 =
(1 - 91%) × 843 =
(100% - 91%) × 843 =
9% × 843 =
9 ÷ 100 × 843 =
9 × 843 ÷ 100 =
7,587 ÷ 100 =
75.87
Calculate absolute change (actual difference)
Absolute change (actual difference) =
New value - 843 =
75.87 - 843 =
- 767.13
Proof.
Calculate percentage decrease:
Percentage decrease =
91% × 843 =
91 ÷ 100 × 843 =
91 × 843 ÷ 100 =
76,713 ÷ 100 =
767.13

Which of the following shows the extraneous solution to the logarithmic equation log7(3x^3+x)-log7(x)=2?
Answer:
x=4
Step-by-step explanation:
on edge
The extraneous solution to the logarithmic equation log₇(3x²+x)-log₇x=2 is x=16
What is logarithm?When you raise a number with an exponent, there comes a result.
Lets say you get[tex]a^b = c[/tex]
Then, you can write 'b' in terms of 'a' and 'c' using logarithm as follows
[tex]b = \log_a(c)[/tex]
'a' is called base of this log function. We say that 'b' is the logarithm of 'c' to base 'a'
We are given the function as;
log₇(3x²+x)-log₇x=2
Domian: 3x²+x>0
x(3x+1)>0
x∈(-∞,-1/3)U(0,∞)
Hence, x∈(0,∞), Thus x∈(0,∞)
In this problem we use the following formula:
[tex]\boxed {log_ax-log_ay=log_a\frac{x}{y}}\displaystyle\\log_7(3x^2+x)-log_7x=2\\\\log_7(x(3x+1))-log_7x=2(1)\\\\log\frac{x(3x+1)}{x} =2(log_77)\\\\log(3x+1)=log_77^2\\\\log_7(3x+1)=log_749\\\\\\\\3x+1=49\\\\3x+1-1=49-1\\\\3x=48\\\\x=16[/tex]

Which graph represents the function g(x) = 3/(x+2) -4?
Answer:
x=-2, y=-4
Step-by-step explanation:I took the test on k12
The required graph of the given function g(x) = 3/(x+2) -4 is given in the image attached below,
Given that,
The graph for the function g(x) = 3/(x +2) - 4 is to be determined.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
g(x) = 3/(x+2) - 4
Since the function has an inverse operator as 1 / (x + 2) the graph for the given function shown in the graph,

Quick prints makes custom t-shirts. They charge $10 for each t-shirt ordered plus a $5 design fee. Which situation best represents y, the total cost to order x t-shirts?
Answer:
y = 10x+5
Step-by-step explanation:
The price of each T-shirt = $10
Design fee on each T-shirt = $5
We need to find the expression for the total cost. Let the total cost be y. So,
Let he has ordered x T-shirts. So,
y = 10x+5
Hence, this is the required solution.
A bag of 12 oranges costs $2.99. What is the cost per orange?
Answer:
4
Step-by-step explanation:
The cost of each orange in the bag is $0.249 (Approx.) by the costing method.

Kevin is 3 times as old as
Daniel. 4 years ago, Kevin was 5 times as old as Daniel.
How old is Daniel now?
Answer:
Daniel is 8 years old now.
Step-by-step explanation:
From the word problem we can make the following two equations:
Let "K" be Kevin's age now and let "D" be Daniel's age now, then...
K = 3D
K - 4 = 5(D - 4)
Now we substate the value of K, and get...
K - 4 = 5(D - 4)
3D - 4 = 5(D - 4)
3D - 4 = 5D - 20
3D - 5D = - 20 + 4
- 2D = - 16
D = 8
Therefore Daniel is 8 years old now.

x = (y/2) - 1
Please help me find the answer.
Answer:
Step-by-step explanation:
Well you didn't give directions on what to solve for,
I'm gonna assume you want to solve for y
x = (y/2) - 1 (add 1 to both sides)
x + 1 = y/2 (multiply both sides by 2)
2(x + 1) = y (distribute the 2)
y = 2x + 2
