jeffys law whats 2+2
Answer:
b
Step-by-step explanation:
x - y = -2
4x - y = 4
[tex] \begin{cases} x - y = - 2 \\ 4x - y = 4 \end{cases}[/tex]
Use the elimination method as it is faster. We have to eliminate the y-term. (You can eliminate the x-term but it takes longer than eliminating y-term.)Simply multiply the negative one in one of the equations.
[tex] \begin{cases} - x + y = 2 \\ 4x - y = 4 \end{cases}[/tex]
We can finally eliminate the y-term by adding both equations.
[tex]( - x + 4x) + (y - y) = 2 + 4 \\ 3x + 0 = 6 \\ 3x = 6 \\ x = \frac{ 6 }{3} \longrightarrow \frac{ \cancel{6}}{ \cancel{3}} = 2 \\ x = 2[/tex]
Substitute the value of x in any given equations. I will substitute in the first equation.[tex]x - y = - 2 \\ 2 - y = - 2 \\ 2 + 2 = y \\ 4 = y[/tex]
Check the answer by substituting the value of x and y in both equations.First Equation
[tex]x - y = - 2 \\ 2 - 4 = - 2 \\ - 2 = - 2 \longrightarrow \sf{true} \: \: \green{ \checkmark}[/tex]
Second Equation
[tex]4x - y = 4 \\ 4(2) - 4 = 4 \\ 8 - 4 = 4 \\ 4 = 4 \longrightarrow \sf{true} \: \: \green{ \checkmark}[/tex]
Hence, the solution is (2,4).
Answer[tex] \begin{cases} x = 2 \\ y = 4 \end{cases}[/tex]

I got this right on edmentum.
Step-by-step explanation:
A price is increased by 5% and is now £756.
Work out the original price.
Answer:
£720
Step-by-step explanation:
100+5 = 105
105% = 756
divide both sides by 105 to find 1%
1% = 7.2
multiply both sides by 100 to find 100%
100% = 720
756/105 X 100 = 720

Explain the slope and the y-intercept
Whoever completes this will get brainliest!!! Needed ASAP!
Answer:
1. slope m = 1; y-intercept b = 3
2. slope m = ; y-intercept b = 4
3. slope m = 3; y-intercept b = 1
4. slope m = [tex]\frac{1}{2}[/tex]; y-intercept b = 1
5. the slope demonstrates the cost of toppings PER topping and how the price increases per topping. the y-intercept is the starting cost WITHOUT toppings (when toppings = 0) and the slope increases the price starting with the y-intercept because it is the initial cost. the graph is attached
Solve for the inequality x / 3 < -7
Answer:
[tex]x < - 21[/tex]
Step-by-step explanation:
1. Multiply both sides by 3.
[tex]x < - 7 \times 3[/tex]
2. Simplify 3 × 7 to 21.
[tex]x < - 21[/tex]
therefor, the answer is x < -21

A house is losing value at a rate of 5.4% per year. In 2009, the house was worth $331,000. Find the value of the house in 2021.
Answer:
$169803
Step-by-step explanation:
Given data
rate of decrease = 5.4%
time = 2009-2021= 12years
P= $331,000
Let us apply the compound interest formula
A=P(1-r)^t----------------note the minus sign because this is a decrease
A= 331000(1-0.054)^12
A= 331000(0.946)^12
A= 331000*0.513
A=$169803
Hence the value in 2021 is $169803

Which of the following functions represents an arithmetic sequence?
1. f(n)=3n^2−4
2.f(n)=3n−4
3.f(n)=3^n−4
4.f(n)=3^n−4^n
Answer:
Option (2)
Step-by-step explanation:
Explicit formula of an arithmetic sequence is always in the linear form.
A(n) = a + (n - 1)d
Here A(n) = nth term of the sequence
a = first term
n = number of term
d = common difference
Formula doesn't have the terms with the exponent.
Therefore, from the given options, expression that represents an arithmetic sequence will be,
f(n) = 3n - 4
Option (2) will be the correct option.

Pls help its my last question?!?!
Answer:
x = -11
m<B = -43
m<C = -22
Step-by-step explanation:
To solve for x, solve (3x-10) + (2x) + 65 to get 5x+55. Simplify to 5x = -55. This can simplify further to x = -11. Insert -11 as x into the angles.
I hope this is correct and helps!

I think you meant to put 5/12 ad 9/16 but in any case, even if it were 51/2 and 91/6 or anything else, the answer would be no
What is 4/9 x 5/7 x 1/2
Answer:
0.16
Step-by-step explanation:
4*5*1=20
9*7*2=126
20/126=10/63
Answer:
10/63
Step-by-step explanation:
First, let's solve 4/9 * 5/7. Multiply the numerator first- 4*5=20. The denominator is 9*7=63. So, this equals 20/63. Now we need to find 20/63 * 1/2. We can cancel out the 2 on the denominator and divide 20 on the numerator by 2. So, you get 10/63 * 1/1, which is 10/63.
