Answer:

The Distributive Property is used, which consists of multiplying the factor by each of the addends.

2x (x-4) = 2x.x-2x.4 = 2 x 2 -8x

It is better to understand what you are doing. Hope this can help you :)

Answer:

slope: $\frac{3}{4}$ ; y-intercept: 1

Step-by-step explanation:

First, you must rearrange the function into y = mx + b form:

2x + x = 4(y - 1)

Simplify both sides:

3x = 4y - 4

Subtract 3x and 4y from both sides:

-4y = -3x - 4

Divide both sides by -4:

y = $\frac{3}{4} x$ + 1

Now that it is in y = mx + b form, you can find the slope and y-intercept. In y = mx + b form, m is the slope and b is the y-intercept. Therefore:

m = $\frac{3}{4}$ = slope

b = 1 = y-intercept

We invested $10000 into two bank accounts. One account earns 14% per year, the other account earns 8% per year. How much did we

Blababa [14]

Answer:

$7,300 was invested in the 14% account while $2,700 was invested in the 8% interest account

Step-by-step explanation:

Let the amount invested in first account be $x while the amount for second account is $y

Mathematically;

x + y = 10,000 •••••••••(i)

Interest on first account

= 14% of x = 14/100 * x

Interest on second account

= 8% of y= 8/100 * y

Adding all together will give total

14/100 * x + 8/100 * y = 1238

Multiply through by 100

14x + 8y = 123800 •••••••(ii)

From equation 1, x = 10,000 - y

Insert this into second equation

14(10,000-y) + 8y = 123,800

140,000 - 14y + 8y = 123,800

140,000 - 6y = 123,800

6y = 140,000 - 123,800

6y = 16,200

y = 16,200/6

y = $2,700

Recall

x + y = 10,000

x = 10000 - y

x = 10,000 - 2,700

x = $7,300

Can anyone help me with this? i dont understand it, thank you.

valina [46]

Answer:

$3(x + 2) = 2(x + 2) \\ 3x + 6 = 2x + 4 \\ 3x - 2x = 4 - 6 \\ x = - 2$

Put these numbers in order from least to greatest 12%, -1/2, 0, -0.22, 0.56

uysha [10]

Answer: -1/2, -0.22, 0, 12%, 0.56

Step-by-step explanation:

-1/2 is equal to -0.50, making it the number with the least value.

-0.22 is closer to 0 than -0.50, meaning it is greater then -0.50 and less than 0.

0 is between the negative and positive numbers, giving it the spot that it has.

12% is equivalent to 0.12, meaning it is more than 0, and less than 0.56, which is the greatest number.

0.56 has more value than any other number in the problem, meaning it goes last in the order.
