Answer: (x,y)=(14/4,0)

Step-by-step explanation:

y=-2(x-3)(2)+2

Clear the brackets

y=-2(2x-6)+2

y=-4x+12+2

y=-4x+14

To get the x-intercept y=0

0=-4x+14

4x=14

x=14/4

(x,y)=(14/4,0)

Which polynomial lists the powers in descending order? A. –10 + 4x3 – 4x5 + 2x4 + x7 B. x7 – 4x5 + 2x4 + 4x3 – 10 C. x7 + 4x3 +

Artist 52 [7]

The answer for the exercise shown above is the option B, which is: $x^{7} -4 x^{5} +2 x^{4} +4 x^{3}- 10$
The explanation is shown below:
To list the powers of the polynomial given in the problem above in descending order, you must write the terms from the highest degree to the lowest degree. You have that the highest degree is $7
$ and the lowest degree is $0
$ (Because $-10 x^{0} =-10(1)=-10$ . Therefore, you have that the correct option is the option B.

Algebra I

Coordinates (x, y)
Midpoint Formula: $\displaystyle (\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})$

Step-by-step explanation:

Step 1: Define

Point (2, 9)

Point (8, 1)

Step 2: Identify

(2, 9) → x₁ = 2, y₁ = 9

(8, 1) → x₂ = 8, y₂ = 1

Step 3: Find Midpoint

Simply plug in your coordinates into the midpoint formula to find midpoint

Substitute in points [Midpoint Formula]: $\displaystyle (\frac{2+8}{2},\frac{9+1}{2})$
[Fractions] Add: $\displaystyle (\frac{10}{2},\frac{10}{2})$
[Fractions] Divide: $\displaystyle (5,5)$

Bowser ate 4 1/2 pounds of dog food. That amount is 3/4 of an entire bag of dog food. How many pound of dog food were originally

GalinKa [24]

Divide number of pounds eaten by the portion of the bag eaten.

= 4 1/2 pounds ÷ 3/4
= 4.5 ÷ 0.75
= 6 pound bag

CHECK:
multiply total pounds of bag by portion eaten
= 6 pound bag * 3/4
= 4 1/2 pounds eaten

ANSWER: The bag was 6 pounds of dog food.

Hope this helps! :)

Find two integers whose sum is -9 and product is -10

BigorU [14]

Step-by-step explanation:

if the two integers are x and y

xy=-10

x+y=-9

x+(-10/x)=-9

x2+9x-10=0

(x-1)(x+10)=0

x=1 or x=-10

if x=1, y=-10

if x=-10, y=1

so the two integers are 1 and -10
