the +4 turns into -4
6-4=2 the (+4-4 on the left would cancel out)
-2x/2 would cancel out as well
2 divided by 2 = 1
you could have used a scientific calculator on google (for future reference)

Use slope to determine if lines PQ and RS are parallel,
perpendicular, or neither.
P(2, -1), Q(-3,-1), R(-11, 9), S(-7, 9)
Answer:
PQ and RS are parallel to each other
Step-by-step explanation:
Slope of two points (x1,y1) and (x2,y2) is given by
slope = (y2-y1)/(x2-x1)
for two lines to be parallel slope should be equalfor two lines to be perpendicular product of slope should be -1_______________________________________________Lets find the slope of PQ and RS
for PQ P(2, -1), Q(-3,-1), R(-11, 9), S(-7, 9)
slope PQ = (-1 -(-1))/(-3 -2) = (-1 + 1)/5 = 0/5 = 0
Slope RS = (9-9)/(-7 - (-11) ) = 0/4 = 0
Since
slope PQ = slope RS = 0
Hence PQ and RS are parallel to each other
Help it’s due tomorrow I’ll mark you as the brainless but please help
Answer:
The slope of a line is
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
Get 2 points off each line
(x1, y1)
(x2, y2)
And sub them into the formula.
The y intercept is where the line cuts the y axis (the vertical line)
From what I can make out the y intercept for the first part in question 12 is (0,-2) and for the third part is (0,0) but I can't see the second one.
It might help if you took a clearer photograph I'm so sorry but I can't really see it.
A piece of wire is 25 cm and has a weight of 10 grams. Another piece of the same wire is 30 cm long. Calculate the weight of the 30 cm piece of wire. working out please
Answer:
75 grams
Step-by-step explanation:
If 25 cm = 10 grams
Then 1 cm = 25/10
1 cm = 2.5 grams
To find 30 cm = 2.5 times 30 grams
30 cm = 75 grams
plz someone help me on this question I rlly need help
Step-by-step explanation:
you simply have to mark the points in which the x and y coordinates are given take for example "1,4" it took him 4 minutes to read 1 page right? the one is marked as X and the 4 is marked as Y so put a point in which the 1 at X and the 4 at Y meet in the coordinates system. Do so with every coordinates and then draw a line in the direction of all the points
just mark down the coordinates on the plane, like this.

Can you please help me?
Answer:
f(2) = 0.5(2) +3.4f(3.5) = 0.5(3.5) +3.4f(15) = 0.5(15) +3.4f(21.3) = 0.5(21.3) +3.4Step-by-step explanation:
Put the given weight where x is in the function definition. You're only asked for the expression, not its value.
f(2) = 0.5(2) +3.4f(3.5) = 0.5(3.5) +3.4f(15) = 0.5(15) +3.4f(21.3) = 0.5(21.3) +3.4luke is baking brownies.he needs 1/2 cup of sugar for each batch of brownies.if he makes 6 batches of brownies,how much sugar will he need
You would like to have $20,000 to use a down payment for a home in five years by making regular, end-of-month deposits in an annuity that pays 6% interest compounded monthly. How much of the $20,000 down payment comes from interest earned? Round your answer to the nearest cent. Do NOT round until you have calculated the final answer. Do NOT include the dollar sign in the answer box below.
Using compound interest, it is found that $5,172.56 comes from interest earned
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year. t is the time in years for which the money is invested or borrowed.In this problem:
$20,000 is required in five years, hence t = 5, A(5) = 20000.Interest rate of 6%, hence r = 0.06.Monthly compounding, hence n = 12.First, we have to find the principal needed, hence:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]20000 = P\left(1 + \frac{0.06}{12}\right)^{12(5)}[/tex]
[tex]P = \frac{20000}{(1.005)^{60}}[/tex]
[tex]P = 14827.44[/tex]
Hence:
$14,827.44 comes from the principal.$5,172.56 comes from interest earned, as $20,000 - $14,827.44 = $5,172.56.To learn more about compound interest, you can take a look at https://brainly.com/question/25781328

Pluto has been hard to measure from Earth because of its atmosphere. In 2007 Young, Young, and Buie measured Pluto as having a diameter of 2322 km. In 2017 new measurements were taken and Pluto is now believed to be 2376.6 km in diameter. Since the older measurement is now considered incorrect, what was the percent error of the 2007 measurement? [enter your answer as a percentage without the % sign] Round to two decimals.
Answer:
The percent error of the 2007 measurement is 2.30
Step-by-step explanation:
To determine the percent error of the 2007 measurement,
Percent error is given by
Percent error = [tex]\frac{|True value - Observed value| }{True value} \times 100%[/tex]%
Observed measurement in 2007 = 2322 km
True value (observed in 2017) = 2376.6 km
∴ Percent error = [tex]\frac{|2376.6 - 2322| }{2376.6} \times 100%[/tex]%
Percent error = [tex]\frac{54.6 }{2376.6} \times 100%[/tex]%
Percent error = 0.022974 × 100%
Percent error = 2.2974%
Percent error ≅ 2.30%
Since the answer is required to be entered without the % sign, then
Percent error = 2.30
Hence, the percent error of the 2007 measurement is 2.30.

Answer:
3600
Step-by-step explanation:
lcm stands for "lowest common multiple"
the lcm is 3600 when done with the prime factorization process
Answer:
3600
Step-by-step explanation:
Express each number as a product of its prime factors, that is
36 = 2² × 3²
75 = 3 × 5²
80 = [tex]2^{4}[/tex] + 5
Now multiply each factor the greatest number of times it occurs in each of the 3 numbers.
2 → 4 times (that is [tex]2^{4}[/tex] )
3 → twice (3² )
5 → twice (5² )
Thus
LCM = [tex]2^{4}[/tex] × 3² × 5² = 16 × 9 × 25 = 3600
Original Function and Transformed function. what is the transformation?
Answer:
A function transformation takes whatever is the basic function f (x) and then "transforms" it (or "translates" it), which is a fancy way of saying that you change the formula a bit and thereby move the graph around. ... Moving the function down works the same way; f (x) – b is f (x) moved down b units.

Which graph shows the points (–3, 5) and (4, –3) plotted correctly?
Answer:
Step-by-step explanation:
This is clearly a linear relationship. If Alex rented the movie for 0 days, he'd owe nothing. If he paid $6 for a 3-day rental, the slope of this line would be m = rise / run = $6/(3 days) = $2/day, which is positive.
Then the equation for this graph is C(x) = ($2/day)x, where x is the number of days for which the movie is rented.
Using this formula, we find three particular points on the graph:
