Answer:

Its the third choice:

(2, 5).

Step-by-step explanation:

6x + 4y = 32

-6x + 4y = 8     Adding the 2 equations:

0 + 8y = 40

8y = 40

y = 5

Now substitute for y in the first equation:

6x  + 4(5) = 32

6x = 32 - 20 = 12

x = 2.

Add equation 1 and 2 to remove 6x. You will end up with
8y = 40
By solving, y=5

Sub 5 into any equation
6x + 4(5) = 32
By solving, x=2
The ordered pair is (2,5)

If (x + 2 ) is a factor of x3 − 6x2 + kx + 10, k =
BartSMP [9]
If a binomial x-a is a factor of a polynomial p(x), then p(a)=0.

x+2 is a factor of p(x)=x³-6x²+kx+10, so p(-2)=0.

p(-2)=0 \\
(-2)^3 - 6 \times (-2)^2 + k \times (-2) + 10=0 \\
-8-6 \times 4-2k+10=0 \\
-8-24-2k+10=0 \\
-2k-22=0 \\
-2k=22 \\
k=\frac{22}{-2} \\
\boxed{k=-11}

What is 5/8 divided by 1/4
Llana [10]

Answer:

Exact form: 5/2

Decimal form: 2.5

Mixed number form: 2 and 1/2

Step-by-step explanation:

when you divide a fraction you keep, change, flip

Equation: 5/8 ÷ 1/4

keep 5/8 the same

change the divide symbol into a multipulcation symbol

flip 1/4 the other way, so it's 4/1 (it's a whole number now)

then just multiply across

Equation now: 5/8 × 4/1

The value of the digit in the tenth place is <u>10 times</u> as much as the digit in the hundredth place.

<h3>What is a digit?</h3>

A digit is a symbol used to construct numerals from 0 to 9, used to represent numbers.

We use the numerals such as 0, 1, 2, 3,4, 5,6,7,8, and 9 to form digits that represent a combination of numbers and do arithmetic operations.

All numerals are made up of the ten digits listed above.

Thus, we can conclude that the value of the digit in the tenth place is <u>10 times</u> as much as the digit in the hundredth place.
