PLZZ Help me
Answer:
y = -2x
Step-by-step explanation
slope intercept form: y = mx + b
m is slope and b is y-intercept
1. lets find y-intercept cuz thats easiest
the line crosses (0,0) at the y-axis so there is no y-intercept
2. to find slope rise/run
we'll start at (0,0) since that's the y-intercept
3. slope is rise/run = -2/1 = -2
it's negative becuase it's going left
_____________________________________________________
another way you can find slope is by the equation y2 - y1/ x2 - x1
take 2 random points from the line, i will use (0,0) and (-2,4)
4 - 0/ -2 - 0 = 4/-2 = -2
slope is -2

A set of speakers costs $22 and songs cost $1.25 each. The sales tax rate is 7.5%. The expression 0.075(22 + 1.25s) can be used to determine the amount of sales tax due on the entire purchase. Expand the expression and round to the nearest hundredth. Drag numbers complete the expression. Numbers may be used once, more than once, or not at all. 0.090.50.971.251.451.6567.5 + s
Answer:
1.65 + 0.09s
Step-by-step explanation:
Given that :
Cost of speaker = $22
Cost per song = $1.25
Sales tax rate = 7.5%
Expression to obtain the amount of sales tax on entire purchase : 0.075(22 + 1.25s)
Expanding the expression :
0.075(22 + 1.25s)
(0.075 * 22) + (0.075 * 1.25s)
1.65 + 0.09375s
Rounding to the nearest hundredth :
Sales tax on entire purchase :
1.65 + 0.09s

Answer:
m = 2
Step-by-step explanation:
The given equation is :
8x – 4y - 9 = 0
The general equation of a line is given by :
y = mx+b ...(1)
here m is slope and b is y-intercept
Equation (1) can be written as :
8x – 4y = 9
Dividing both sides by (-4)
[tex]\dfrac{8x}{-4}-\dfrac{4y}{-4}=\dfrac{9}{-4}\\\\-2x+y=-\dfrac{9}{4}\\\\y=2x+\dfrac{-9}{4}[/tex] ...(2)
Comparing equation (1) and (2), we get :
m = 2
Hence, the slope of the line is 2.

Write the equation of the line PERPENDICULAR to x = -12 passing through (4,5)
Answer:
hope ithelps :)
Step-by-step explanation:
1) x=3 is a vertical line, so if you are looking for a line that is perpendicular you are looking for a horizontal line.
And horizontal lines go through the y-axis and have equations of y= a #
2)the point on the vertical line is (4,-5), it has a y-value of -5
****Every y value on a horizontal line will be the same
so the equation for a perpendicular line would be y= -5
What is 2/19 as a percentage?
Give your answer rounded to one decimal place.
Answer:
10.53%
Step-by-step explanation:
The first step is to divide 2 by 19 to get the answer in decimal form: 2 / 19 = 0.1053 Then, we multiplied the answer from the first step by one hundred to get the answer as a percentage: 0.1053 * 100 = 10.53%
Answer:
11%
Step-by-step explanation:
Divide 2 by 19 and then move the decimal place twice to the right. It should be 10.5 but if rounded it becomes 11 so 11%

what is the expression for f(x) when we rewrite 64^x/4^5x-1 as 4^f(x)
Answer: f(x)= -2x+1
Step-by-step explanation:
The expression for f(x), when we rewrite [tex]\frac{64^x}{4^{5x-1}}[/tex] as [tex]4^{f(x)}[/tex] will be [tex]4^{-2x+1}[/tex].
What is expression ?Expression is a finite combination of symbols that is well-formed according to rules that depend on the context.
We have,
[tex]\frac{64^x}{4^{5x-1}}[/tex]
So,
Now, to rewrite in form of [tex]4^{f(x)}[/tex],
So,
Rewrite the given expression in the form of 4,
i.e.
[tex]\frac{64^x}{4^{5x-1}}[/tex]
[tex]=\frac{(4^3)^x}{4^{5x-1}}[/tex]
[tex]=\frac{(4^3x)}{4^{5x-1}}[/tex]
NOw,
Using Exponent rule,
We get,
[tex]=4^{3x-(5x-1)}=4^{3x-5x+1}[/tex]
On solving we get,
[tex]=4^{-2x+1}[/tex]
So,
[tex]4^{f(x)}=4^{-2x+1}[/tex]
Hence, we can say that the expression for f(x), when we rewrite [tex]\frac{64^x}{4^{5x-1}}[/tex] as [tex]4^{f(x)}[/tex] will be [tex]4^{-2x+1}[/tex].

Answer:
(2 n)/3-2/3 = n/6+4/3
(2 n)/3-2/3 = (2 n-2)/3:
(2 n-2)/3 = n/6+4/3
Put each term in n/6+4/3 over the common denominator 6: n/6+4/3 = n/6+8/6:
(2 n-2)/3 = n/6+8/6
n/6+8/6 = (n+8)/6:
(2 n-2)/3 = (n+8)/6
Multiply both sides by 6:
(6 (2 n-2))/3 = (6 (n+8))/6
6/3 = (3×2)/3 = 2:
2 (2 n-2) = (6 (n+8))/6
(6 (n+8))/6 = 6/6×(n+8) = n+8:
2 (2 n-2) = n+8
Expand out terms of the left hand side:
4 n-4 = n+8
Subtract n from both sides:
(4 n-n)-4 = (n-n)+8
4 n-n = 3 n:
3 n-4 = (n-n)+8
n-n = 0:
3 n-4 = 8
Add 4 to both sides:
3 n+(4-4) = 8+4
4-4 = 0:
3 n = 8+4
8+4 = 12:
3 n = 12
Divide both sides of 3 n = 12 by 3:
(3 n)/3 = 12/3
3/3 = 1:
n = 12/3
The gcd of 12 and 3 is 3, so 12/3 = (3×4)/(3×1) = 3/3×4 = 4:

It is estimated that there are 1.2×1057 atoms in the Sun. The number of atoms in the rest of the Solar System is approximately 1.2×1056. About how many more atoms exist in the Sun than in the rest of the Solar System? Drag numbers to complete the answer in scientific notation.
Answer:
1.08 * 10^57
Step-by-step explanation:
Given that:
Number of atoms in the sun = 1.2 * 10^57
Number of atoms in the rest of the solar system = 1.2 * 10^56
About how many more atoms exist in the Sun than in the rest of the Solar System?
Subtract the number of atoms in solar system from number of atoms in sun
(Number of atoms in sun - number of atoms in rest of the solar system)
(1.2 * 10^57) - (1.2 * 10^56)
= 1.08 * 10^57 (using calculator)
How do you graph Y=1.2x-4 ?
Step-by-step explanation:
Use the y=mx+b reference
the b refers to the y intercept which in your case is -4
so on the graph you would put -4 on the y line so at (0,-4)
Then the m or the slope which is 1.2 means from the point (0,-4) you move 1.2 units up and 1 unit to the right forever to create your line so you continuously move 1.2/1 and -1.2/-1
The required, graph of the linear equation y = 1.2x-4 is shown in the image attached below.
To graph the equation y = 1.2x - 4:
Set up the coordinate plane with the x and y axes.Label the axes as "x" and "y" with numerical markers.Plot the y-intercept: When x = 0, y = 1.2 * 0 - 4 = -4. Plot the point (0, -4).Identify the slope: The coefficient of x is 1.2, which represents the slope.Use the slope to find another point: Starting from (0, -4), move 1 unit to the right (increase x by 1) and 1.2 units upward (increase y by 1.2). Plot the point (1, -2.8).Draw a straight line through the two points you plotted.The graph of Y = 1.2x - 4 will be a straight line that passes through the points (0, -4) and (1, -2.8), and it will continue infinitely in both directions. The line will slope upwards from left to right with a slope of 1.2.
