7 0

Answer:

1/2

Step-by-step explanation:

substitute -2 for x.

any number to negative power  must be flipped.  2^-2 = 1/(2^2) = 1/4

(2)(2^-2) = (2)(1/4) = 2/4 = 1/2

Jose has 1000$ in his savings account. it pays out 5% interest what is his balance after 1 year
NARA [144]

The most appropriate choice for simple interest will be given by- Balance of Jose after 1 year is $1050

What is simple interest?

Simple interest is the interest applied on the principal value after charging some certain percentage of rate for some certain amount of time.

If the principal value is p, rate is r % per annum and time is t years

Simple interest is calculated as

SI = p ₓ r ₓ t / 100

Here,

Principal for Jose = $1000

Rate = 5%

Time = 1 year

Simple interest = 1000x5x1/100

                         = $50

Amount = $(1000+50)

             = $1050

Balance of Jose after 1 year is $1050

The sum of two integers is 121. The larger integer is 7 more than twice the smaller integer. Find the two integers.
iren [92.7K]
X + (2x + 7) = 121 : Write the expression.
3x + 7 = 121 : Combine like terms.
3x + 7 - 7 = 121 - 7 : Isolate x.
3x = 114 : Combined like terms.
3x / 3 = 114 / 3 : Find the value of x.
x = 38 : This is the smaller integer.
(2x + 7) = (2(38) + 7) = 76 + 7 = 83. : Find the value of the larger number by plugging in the value of x to the larger number's quantity.
The larger number is 83, and the smaller number is 38.

Determine the factors of x2 − 8x − 12. (x − 6)(x 2) (x 3)(x − 4) prime (x 6)(x − 2)
Ivanshal [37]

The polynomial cannot be factored in because it exists prime. Since 112 exists not a perfect square number so we cannot estimate the factors of the given equation.

<h3>What is a quadratic equation?</h3>

In a quadratic equation ax² + bx + c = 0

when (b² - 4ac) exists a perfect square only then we can factorize the equation.

In the given equation x² - 8x - 12 we have to determine the value of

b² - 4ac

From the equation, we get b = -8 and c = -12

b²- 4ac = (-8)² - 4(1)(-12)

= 64 + 48 = 112

Since 112 exists not a perfect square number so we can not estimate the factors of the given equation.

Can someone solve 2x-3y=9 and give me the slope and y intercept SHOW WORK please
Dominik [7]

Answer:

The slope is 2/3 and the y-intercept is -3

Step-by-step explanation:

First you subtract 2/3 from both sides and get -3y=-2x+9. Then you divide -3 by -2 and -3 by 9 to get y=2/3-3.

Hope this helped I am not good at explaining but I did this unit like two months ago.
