An item has a listed price of $70. If the sales tax rate is 3%, how much is the sales tax (in dollars)?
3% of 70 means "0.03 x 70" which is 2.1.
The sales tax is $2.10.
Find an equation of a line that passes through the points (-2,-4) and (2,-6)
Answer:
y = -2/4x -5
Step-by-step explanation:
Assuming that the answer will be in slope intercept form, and not standard form. It would go a little like this:
Finding the slope:
y2 - y1/x2 - x1
-6 - (-4) / 2 -(-2)
-6 + 4 / 2 + 2
-2/4
Simplifying further, the slope would be: -1/2
The slope would be -1/2.
Now, checking desmos, the equation would be: y = -2/4x -5.

I am a 3-digit number. If you switch my first and last digits, I decrease by 297. Also, my
middle digit is 6 less than my first digit, which is 2 less than 2 times my last digit. What
number am I?
Answer:
865Step-by-step explanation:
Let the 3-digit number is abc = 100a + 10b + c.
We have:
100a + 10b + c - 100c - 10b - a = 297b = a - 6a = 2c - 2Simplify the first equation:
99a - 99c = 297a - c = 3a = c + 3Solve for c by substitution:
2c - 2 = c + 32c - c = 3 + 2c = 5Find a:
a = 3 + 5 = 8Find b:
b = 8 - 2 = 6The number is:

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar(s). Triangle ABC is defined by the points A(2,9), B(8,4), and C(-3,-2). Complete the following equation for a line passing through point C and perpendicular AB.
The equation of perpendicular line is [tex]$y=-\frac{11}{6} x+\frac{43}{6}[/tex].
What is the equation of a Straight Line ?The equation of the straight line is represented by
y = mx + c
where m is the slope , and c is the intercept on y axis.
Calculate the slope m of BC using the slope formula
[tex]$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}$[/tex]
with [tex]$\left(\mathrm{x}_{1}, \mathrm{y}_{1}\right)=\mathrm{B}(8,4)$[/tex] and [tex]$\left(\mathrm{x}_{2}, \mathrm{y}_{2}\right)=\mathrm{C}(-3,-2)$[/tex]
[tex]$m_{B C}=\frac{-2-4}{-3-8}=\frac{6}{11}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]$m_{\text {perpendicular }}=-\frac{1}{m}=-\frac{1}{\frac{-6}{11}}=-\frac{11}{6}$[/tex], then
[tex]$y=-\frac{11}{6} x+c[/tex] is the partial equation
To find c substitute A(3,8) into the partial equation
[tex]$9=-\frac{-11}{6}+C[/tex]
[tex]$-\left(-\frac{11}{6}\right)+C=9$$[/tex]
Apply rule -(-a)=a
[tex]$\frac{11}{6}+C=9$$[/tex]
Subtract [tex]$\frac{11}{6}$[/tex] from both sides
[tex]$\frac{11}{6}+C-\frac{11}{6}=9-\frac{11}{6}$$[/tex]
Simplify
[tex]$C=\frac{43}{6}$$[/tex]
[tex]$y=-\frac{11}{6} x+\frac{43}{6}[/tex] be the equation of perpendicular line.
Therefore, the value of c = 43/6.

You are installing solar lighting units alongs the driveway to your house. Each unit is on sale for $12. You purchase 15 units. show how you can use the distributive property to find the total cost of the lighting units mentally.
Answer:
$180
Step-by-step explanation:
(12*10)+(12*5)
12*5 = 120/2 = 60 (half of 12*10)
12*10= 120
120 + 60= $180
You don't even have to calculate (12*5) you can just do 12*10/2

Suppose that the maximum weight that a certain type of rectangular beam can support varies inversely as it’s length and jointly as its width and the square of its height. Suppose also that a beam 5 inches wide, 2 inches high and 10 feet long can support a maximum weight of 8 tons. What is the maximum weight that could be supported by a beam that is 6 inches wide, 2 inches high, and 24 feet long
Way: W = k * w * h^2/ L
4 tons is maximum weight that could be supported by a beam that is 6 inches wide, 2 inches high, and 24 feet long
What is Weight?Gravitational force of attraction on an object, caused by the presence of a massive second object, such as the Earth or Moon.
Given,
Maximum weight that a certain type of rectangular beam can support varies inversely as it’s length and jointly as its width and the square of its height.
beam 5 inches wide, 2 inches high and 10 feet long can support a maximum weight of 8 tons.
W = k × w × h²/ L
8 = k × 5 × 2² / 10
8 = k ×20/10
8 = 2 × k
k = 4
The maximum weight that could be supported by a beam that is 6 inches wide, 2 inches high, and 24 feet long
w =4 ×6 ×2² / 24
= 24 ×4/ 24
W=4 tons
Hence 4 tons is maximum weight that could be supported by a beam that is 6 inches wide, 2 inches high, and 24 feet long

1. Suppose C(x) is a function representing the cost(in dollars) of producing x units energy, and R(x) is a function representing the revenue (in dollars) of selling x units of energy. Suppose further that both functions are continuous for all x > = 0. A. Is there necessarily some x value, let's call it C, that will maximize profit over all x = 0? Explain your answer. B. Suppose we know we can't produce more than 1,000 units of energy. Is there necessarily some x-value, call it C, that will maximize profit over the interval [0,1000]? Explain your answer. C. Again, assume that we can't produce more than 1,000 units of energy. Is there necessarily some x value, let's call it C, for which the profit is exactly 0? Explain your answer.
Answer:
A. Yes, there is a value that will maximize the profit overall x values. This is true when the functions C(x), R(x), and P(x) are often defined only for non-negative integers, that is, for x = 0, 1, 2, 3... . The reason is it is not logical to speak about the cost of producing −1 cars or the revenue generated by selling 3.62 refrigerators. Thus, each function may give rise to a set of discrete points on a graph.
The formulas for these questions are:
C(x) = cost of producing x units of the product
R(x) = revenue generated by selling x units of the product
P(x) = R(x) − C(x) = the profit (or loss) generated by producing and (selling x units of the product.)
B. No, there is not an x-value that will maximize the profit over [0,1000]. This is true since 1,000 is the horizontal asymptote, which means that the line of the graph keeps traveling with the HA until the profits drop since we cannot produce anything more than 1,000 units of energy per day. The graph of this problem would be a horizontal asymptote at y = 1,000. The line of the graph would start at zero and increase until it reaches the asymptote at 1,000 and continues towards infinity.
C. Yes, there is an x-value that is exactly zero. This is true because zero is our starting point in our profits. The x and y value would be (0,0) as we have just begun to produce energy units. Once the graph starts to increase, we cannot have a point at exactly zero, unless the profits have a dramatic drop to the x value of 0. This would then be (0, at a number of diminishing returns)
