PLEASEE HELP!!

So you know each french fry equals 25 calories. So amount of calories per french fry = 25f
Similarly we know each chicken wing has 100 calories so amount per chicken wing = 100c
So total calories = 25f+100c
Now we know that we want the total to be less than 500
Therefore the inequality should look like this
25f+100c<500

Slope = rise over run = the change in y over the change of x
if you want it to be exactly 2, then you have to make sure the equations are proportional.
-5 - y / 6-1
so you simplify it -5-y/ 5
the answer needs to be 2 times 5,
2 x 5 = 10, so you need to add 5 because that's what you subtract from it in the end.
y = 15

Answer:

12) B --> x < 8/3

13) B --> x ≤ 1/6

Step-by-step explanation:

12) Solving inequalities is just like solving normal equations where you and add, subtract, multiply and divide sides by the same value. Keep in mind dividing or multiplying by a negative flips the sign:

x - 10 < 6 - 5x

Add 5x to both sides to combine the x terms:

x - 10 < 6 - 5x

+5x +5x

6x - 10 < 6

Add 10 to both sides to isolate the x term:

6x - 10 < 6

+10 +10

6x < 16

Now, divide by 6 on both sides:

x < 8/3, this is B

13) Simplify 2 - 4:

2-3(2x + 1) ≤ 6x(-2)

Distribute:

2 - 6x - 3 ≤ -12x

Add 12x to both sides and combine like terms:

6x - 1 ≤ 0

Add 1 to both sides:

6x ≤ 1

Divide by 6:

x ≤ 1/6, this is B

Which ordered pair could not be the coordinates for a clockwise rotation of the point W(-3, 4)?

Eduardwww [97]

Step-by-step explanation:

Look at the picture.

Any pair of choice can be the coordinates of the rotation of the point

W (-3, 4) clockwise.

All points have the same distance from the beginning.

The formula of a distance between the origin and a point (x, y):

$d=\sqrt{x^2+y^2}$

W(-3, 4)

$d=\sqrt{(-3)^2+4^2}=\sqrt{9+16}=\sqrt{25}=5$

(3, -4)

$d=\sqrt{3^2+(-4)^2}=\sqrt{9+16}=\sqrt{25}=5$

(4, 3)

$d=\sqrt{4^2+3^2}=\sqrt{9+16}=\sqrt{25}=5$

(-4, -3)

$d=\sqrt{(-4)^2+(-3)^2}=\sqrt{9+16}=\sqrt{25}=5$

(-4, 3)

$d=\sqrt{(-4)^2+3^2}=\sqrt{9+16}=\sqrt{25}=5$

Can you help me im not that good at math and its a clear photo y =___x^2+__x+______

Vertex/General Form: y = a(x - h)^2 + k, with (h,k) as the vertex
(x + y)^2 = x^2 + 2xy + y^2
Standard Form: y = ax^2 + bx + c

So before I put the equation into standard form, I'm first going to be putting it into vertex form. Since the vertex appears to be (-1,7), plug that into the vertex form formula:

$y=a(x-(-1))^2+7\\y=a(x+1)^2+7$

Next, we need to solve for a. Looking at this graph, another point that is in this line is the y-intercept (0,5). Plug (0,5) into the x and y placeholders and solve for a as such:

$5=a(0+1)^2+7\\5=a(1)^2+7\\5=a+7\\-2=a$

Now we know that our vertex form equation is y = -2(x + 1)^2 + 7.

However, we need to convert this into standard form still, and we can do it as such:

Firstly, solve the exponent: $y = -2(x^2+2x+1) + 7$

Next, foil -2(x^2+2x+1): $y = -2x^2-4x-2+7$

Next, combine like terms and your final answer will be: $y = -2x^2-4x+5$
