standard form is ax+by=c so
y=-2/3x+4
add 2/3x to both sides
2/3x+y=4
make whole numbers for niceness
multipily by 3 to clear fraction
2x+3y=12

answer is second one
We know that the standard form is
ax + by = c
So, let's solve this problem to get correct answer
y = -2/3x + 4 { multiplying each term by 3 }
3y = -2x + 12  { according to the standard form equation our x variable should be on other side so let move that} { adding 2x on both sides }
2x + 3y =  12 
 Hence the correct option is B.

If you want to check your answer resolve your answer and see if you get the same quotient.
2x + 3y = 12
3y = -2x + 12 { subtracting both sides by -2x }
y = -2/3x + 12/3 {dividing both sides by 3 } 
y = -2/3x + 4 { same as the quotient }

Hence proved.

X2 - x - 6 =Simplified. I know the answer is (x+2)(x-3), but I don't understand how the answer was achieved. Can I please get an explanation of this?

Answers

x^2-x-6=(x+2)(x-3)\n\n-x=2x-3x\n-6=2*(-3)\n\nor\n\nx^2-x-6=x^2+2x-3x-6=x(x+2)-3(x+2)=(x+2)(x-3)
I had a lot of trouble with this when my algebra class started doing it,
a long time ago.

The key is this:  Look at the -6 at the end.  You have to find two factors
of that number that add up to the -1 in the middle.

Here are the possible factors of -6 :

-1 ... 6
+1 ... -6
-2 ... 3
+2 ... -3

Can you find a pair on the list that adds up to -1 ? 
How about +2 and -3 ?
Their product is -6 and their sum is -1.  That's what you need.

Now set up a couple of binomial factors like this:  (x....) (x....)
and write in the pair of numbers you found:  (x + 2) (x - 3)
That's the factored form of the original expression.

Magda sold her car for $1,900. This was $300 less than twice the original purchase price. What was the original price of Magda's car? Let p represent the original price of the car.A .2p - 300 = 1,900; p = 1,100
B .300p = 1,900 + 2; p = 634
C .300 - 2p = 1,900; p = 800
D .2p = 1,900 - 300; p = 800

QUESTION 6 6.1 The following marks out of 50 were scored by learners in a Mathematics test. 41 33 26 14 45 23 24 27 13 33 12 6.1.1 Write down the range. 6.1.2 What is the modal mark? 6.1.3 Calculate the mean of the marks correct to two decimal places. 6.1.4 Determine the median mark.​

Answers

Answer:

The range of a set of numbers is the difference between the highest and lowest values. In this case, the highest mark is 45 and the lowest mark is 6.1.1 Therefore, the range is 45 - 6.1.1 = 38.9.

The government’s claims that students earn an average of $4,500 during their summer break from studies. A random sample of students gave had a sample average of $3,975 and a 95% confidence interval was found to be $3,525 < µ < $4,425. This interval is interpreted to mean that:a. because our specific confidence interval does not contain the value $4500 there is a 95% probability that the true average summer earnings is not $4500.b. if we were to repeat our survey many times, then about 95% of all the confidence intervals will contain the value $4500.c. if we repeat our survey many times, then about 95% of our confidence intervals will contain the true value of the average earnings of students.d. there is a 95% probability that the true average earnings are between $3525 and $4425 for all students.
