Answer:
y = -4/3x +4
Step-by-step explanation:
6y + 8x = 24
Subtract 8x from each side
6y + 8x-8x = -8x+24
6y = -8x+24
Divide each side by 6
6y/6 = -8x/6 +24/6
y = -4/3x +4
Which of the following points lies on the line whose equation is y=2x-3?
(-1,4) (1, -1)
(0,3)
Answer:
(1, -1)
Step-by-step explanation:
y - (-1) = 2 (x - 1)
y + 1 = 2x - 2
y = 2x - 2 - 1
y = 2x - 3
Answer:
Option B: (1,-1)
Step-by-step explanation:
To solve these types of questions, you must first draw the graph. Then, you can see which point is on the line.
(I personally use Desmos's Graphing Calculator for the graph. Just put the equation in, and the line is drawn for you!)

Molly bought a flat. At the beginning of
the third year, the value of Molly's flat had
increased to €363 000. At the beginning of
the fifth year, the value had increased to
€439 230.
a Calculate the rate of increase.
b Calculate how many euros Molly
originally paid for the flat.
C Find how much the flat is worth at the
beginning of the ninth year.
The rate of increase is 1.1, Molly originally paid 272727 for the flat and its worth at the beginning of the ninth year. is 643076
Calculating the rate of increase.From the question, we have the following parameters that can be used in our computation:
Third year = 363000
Fifth year = 439230
So, we have
Rate² = 439230/363000
Evaluate
Rate² = 1.21
Take the square root
Rate = 1.1
Calculating how many euros Molly originally paid for the flat.An exponential function is represented as
f(x) = abˣ
Where
a = initial values
Using the values from the third year, we have
a * 1.1³ = 363000
So, we have
a = 363000/1.1³
Evaluate
a = 272727
The flat worth at the beginning of the ninth year.This means that
x = 9
So, we have
f(x) = 272727 * 1.1⁹
Evaluate
f(x) = 643076
Hence, the flat worth at the beginning of the ninth year. is 643076

The ideal width of a safety belt strap for a certain automobile is 6 cm. The actual width can vary by at most 0.45 cm. Write an absolute value inequality for the range of acceptable widths and solve the inequality.
Answer:
[tex]|x-6|\le 0.45[/tex]
[tex]x\in [5.55,6.45][/tex]
Step-by-step explanation:
Absolute Value Inequality
Assume the actual width of a safety belt strap for a certain automobile is x. We know the ideal width of the strap is 6 cm. This means the variation from the ideal width is x-6.
Note if x is less than 6, then the variation is negative. We usually don't care about the sign of the variation, just the number. That is why we need to use the absolute value function.
The variation (unsigned) from the ideal width is:
[tex]|x-6|[/tex]
The question requires that the variation is at most 0.45 cm. That poses the inequality:
[tex]|x-6|\le 0.45[/tex]
That is the range of acceptable widths. Let's now solve the inequality.
To solve an inequality for an absolute value less than a positive number N, we write:
[tex]-0.45\le x-6 \le 0.45[/tex]
This is a double inequality than can be easily solved by adding 6 to all the sides.
[tex]-0.45+6\le x \le 0.45+6[/tex]
Operating:
[tex]5.55\le x \le 6.45[/tex]
That is the solution in inequality form. Expressing in interval form:
[tex]\boxed{x\in [5.55,6.45]}[/tex]
The numeraiders won 7 games, lost 9 games and tied 2 games. What percent of the games did they win?
Answer:
0.39%
Step-by-step explanation:
7+9+2= 18
7 divided by 18 and you'll get 0.38%. If you round it up it's 0.39%.
Answer:
39% of the games they won
Step-by-step explanation:
7+9+2=18
so there were 18 games in total and they won 7 of those games so they won 7/18 of the games.
You divide 7/18 and get 0.388888... you would round to the nearest hundredth place and get 0.39
To change a decimal to a percent you multiply by 100 and get 38%

An honest coin is tossed 4 times in a row. Find the probability of each of the following events. (a) E1: "The coin comes up tails exactly twice." (b) E2: "All 4 tosses come up the same." (c) E3: "Exactly one-third of the tosses come up ." (d) E4: "The first 2 tosses come up heads ."
Answer:
3/8 ; 1/8 ; 0 ; 1/4
Step-by-step explanation:
Given that:
For a coin toss :
Sample space = {HHTT, HTTT, THTT, TTTT, HHHT, HTHT, THHT, TTHT, HHTH, HTTH, THTH, TTTH, HHHH, HTHH, THHH, TTHH}
Probability = required outcome / Total possible outcomes
a) E1: "The coin comes up tails exactly twice."
p(E1) = 6/16 = 3/8
(b) E2: "All 4 tosses come up the same."
{TTTT, HHHH}
p(E2) = 2/16 = 1/8
(c) E3: "Exactly one-third of the tosses come up head."
1/3 of 4 ; p = 0 ; outcome is not a whole number
(d) E4: "The first 2 tosses come up heads ."
P(E4) = 4/16 = 1/4

Answer:
e) Horizontal translation to the right of 2 units and vertical translation down of 4 units.Step-by-step explanation:
Given
f(x) = 5^(x-2) - 4which is the result of the transformation of the function g(x)= 5^x
We can see that
f(x) = g( x - 2) - 4This is indicating horizontal shift 2 unit to the right and vertical shift 4 units down
