Answer:

  (3, 8) is a solution of the system

Step-by-step explanation:

We assume your second equation is intended to be ...

  y = 2^x

This system of equations can be solved graphically or by trial and error. There are no algebraic methods for solving it.

A graph shows that (3, 8) is one of the two solutions.

Step 1:  Subtract 87 from both sides

[tex]2x^2 - 11 - 87 = 87 - 87[/tex]

[tex]2x^2 - 11 - 87 = 0[/tex]

Step 2:  Factor

[tex]2x^2 - 11 - 87 = 0[/tex]

[tex]2(x + 7)(x - 7) = 0[/tex]

[tex]x + 7 = 0[/tex] and [tex]x - 7 = 0[/tex]

[tex]x = -7[/tex] and [tex]x = 7[/tex]

Answer:  [tex]x = -7, 7[/tex]

Answer:

x = 7, -7

Step-by-step explanation:

2x² - 11 = 87

2x² = 98

x² = 49

x = +/-7

Answer:

  {-15, -5}

Step-by-step explanation:

The constant on the left needs to be the square of half the x-coefficient:

  (20/2)^2 = 100

To get it to that value, we can add 18 to both sides of the equation:

  x^2 +20x +100 = 25 . . . add 18 to both sides of the equation

  (x +10)^2 = 25 . . . . . . .  . write the left side as a square

  x +10 = ±√25 = ±5 . . . . . take the square root

  x = -10 ±5 = {-15, -5}

The solutions are x = -15 and x = -5.

Answer:

A= 30 sq. cm

Step-by-step explanation:

We want to find the area of both triangles seprately than add them together. For the area of a traingle, we use the equation 1/2 base times height. For triangle ABE we do this:

[tex]A = \frac{1}{2} (12)(4)[/tex]

[tex]A = (6) (4)[/tex]

[tex]A = 24[/tex]

For triangle BDC, we do this:

[tex]A = \frac{1}{2} (6) (2)[/tex]

[tex]A = (3) (2)[/tex]

[tex]A=6[/tex]

Now we have to add both areas ot get A=30 sq cm

Answer:

0.136m

Step-by-step explanation:

This is because if you draw a diagram, and label all the sides of the triangle (opp, hyp, adj), the adjacent angle is 3m. You can now use the sine rule to find the hypotenuse (length of ladder) by doing: cos 20= 3/h. You divide cos(20) by 3 and you get the answer of 0.13602m.

Answer:

Tina could make are 10 Possible total points.

They number of possible total points are; 18, 19, 20, 21, 22, 23, 24, 25, 26 and 27.

Step-by-step explanation:

This is a zero-sum sort of deal. If tina makes 9 baskets, they can be all 2 points or all 3 points.

Let's make some number of 2 points "n". Then, the number of 3 points has to be 9 - n. The logic is exactly the same if we considered the number of 3 points made to be "n".

Thus, the maximum of this relationship is when n = 0.

Hence, 9 baskets gives the following possible permutations:

1) 0 number of 2 points and 9 number of 3 points = 27 points

2) 1 number of 2 points and 8 number of 3 points = 26 points

3) 2 number of 2 points and 7 number of 3 points = 25 points

4) 3 number of 2 points and 6 number of 3 points = 24 points

5) 4 number of 2 points and 5 number of 3 points = 23 points

6) 5 number of 2 points and 4 number of 3 points = 22 points

7) 6 number of 2 points and 3 number of 3 points = 21 points

8) 7 number of 2 points and 2 number of 3 points = 20 points

9) 8 number of 2 points and 1 number of 3 points = 19 points

10) 9 number of 2 points and 0 number of 3 points = 18 points

So the number of possible points Tina could make are; 18, 19, 20, 21, 22, 23, 24, 25, 26 and 27.

Step-by-step explanation:

Your multiplying the Squares together and then adding them

Blue Square : x*x= x^2

Pink  Square : x*7= 7x

Green Square: x*3= 3x

Orange Square: 3*7= 21

Now we add all the squares together to get the total area.

Answer:

Option c. 5.7 grams

Option b. 5.3 grams

Step-by-step explanation:

(a) A [tex]4\frac{1}{2}[/tex] ounce hamburger patty has [tex]25\frac{1}{2}[/tex] grams of protein.

first we convert mixed fraction to improper fraction.

Amount of protein a  [tex]\frac{9}{2}[/tex] ounce hamburger patty has = [tex]\frac{51}{2}[/tex] grams

∴  Amount of protein a 1 ounce hamburger patty has = [tex]\frac{\frac{51}{2} }{\frac{9}{2} }[/tex]

= [tex]\frac{51}{2} \times \frac{2}{9}[/tex]

= [tex]\frac{51}{9}[/tex]

= [tex]\frac{17}{3}[/tex] = [tex]5\frac{2}{3}[/tex] = 5.7 grams

(b)  A 6 ounces of fish has 32 grams of protein.

∴ The amount of protein a 1 ounce of fish has = [tex]\frac{32}{6}[/tex]

                                                                            = 5.3 grams

A hamburger patty has approximately 5.7 grams of protein per ounce.

A fish has approximately 5.3 grams of protein per ounce.

Answer:

(x + 5)² + (y - 7)² = 13

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k) = (- 5, 7) and r = [tex]\sqrt{13}[/tex] , thus

(x - (- 5))² + (y - 7)² = ([tex]\sqrt{13}[/tex] )² , that is

(x + 5)² + (y - 7)² = 13 ← equation of circle

Answer:

x - 2

Step-by-step explanation:

First, we know that the area of a triangle can be found using the formula: a = 1/2(bh).

We also know that the area of this triangle can be represented by (x^2-4).

Lastly, we know that one of the legs (let's call it the base) can be represented by (2x+4).

Let's plug in those values to the original formula: x^2 - 4 = 1/2(2x + 4)h

Now, let's solve for h!

We can multiply both sides by 2, then divide each side by (2x + 4) to isolate/solve for h.

If you need help on dividing polynomials, feel free to reach out!! I'd be happy to explain.

h = (x - 2)
