Answer:

There is no answer

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

8+9p=9p−7

8+9p=9p+−7

9p+8=9p−7

Step 2: Subtract 9p from both sides.

9p+8−9p=9p−7−9p

8=−7

Step 3: Subtract 8 from both sides.

8−8=−7−8

0=−15

Answer: There are no solutions.

Step-by-step explanation: So the way you do this is by subtracting 9p from both sides, which gets you:

8 = -7

Since 8 is not equal to -7, there is no solution to this equation.

Write the equation of the parabola that has its x-intercepts at (1+<img src="https://tex.z-dn.net/?f=%5Csqrt%7B5%7D" id="TexForm

Answer:

$y=2x^2-4x-8$

Step-by-step explanation:

<u>Factored form of a parabola</u>

$y=a(x-p)(x-q)$

where:

p and q are the x-intercepts.
a is some constant.

Given x-intercepts:

(1+√5, 0)
(1-√5, 0)

Therefore:

$\implies y=a(x-(1+\sqrt{5}))(x-(1-\sqrt{5}))$

$\implies y=a(x-1-\sqrt{5})(x-1+\sqrt{5})$

To find a, substitute the given point (4, 8) into the equation and solve for a:

$\implies a(4-1-\sqrt{5})(4-1+\sqrt{5})=8$

$\implies a(3-\sqrt{5})(3+\sqrt{5})=8$

$\implies4a=8$

$\implies a=2$

Therefore, the equation of the parabola in factored form is:

$\implies y=2(x-1-\sqrt{5})(x-1+\sqrt{5})$

Expand so that the equation is in standard form:

$\implies y=2(x^2-x+\sqrt{5}x-x+1-\sqrt{5}-\sqrt{5}x+\sqrt{5}-5)$

$\implies y=2(x^2-x-x+\sqrt{5}x-\sqrt{5}x+\sqrt{5}-\sqrt{5}+1-5)$

$\implies y=2(x^2-2x-4)$

$\implies y=2x^2-4x-8$

What is a irregular concave polygon

Anvisha [2.4K]

Answer:

An irregular polygon is any polygon that is not a regular polygon. It can have sides of any length and each interior angle can be any measure. They can be convex or concave, but all concave polygons are irregular since the interior angles cannot all be the same.

Use the expression to solve the total calories in 17 Big Macs:
550(17) = 9350

THEREFORE, there are 9350 calories in 17 Big Macs.
