Answer:

4) [tex]y=-\frac{1}{3} (x-2)^2-3[/tex]   7) [tex]2x^2+12x+18[/tex]

5) [tex](-2,-3)[/tex]                    8) [tex](0,-3)[/tex]                            

Step-by-step explanation:

7) Add [tex]2y^2[/tex] to both sides of the equation.

    [tex]x-12y-18=2y^2[/tex]

    Add 12y to both sides of the equation.

    [tex]x-18=2y^2+12y[/tex]

    Add 18 to both sides of the equation.

    [tex]x=2y^2+12y+18[/tex]

    Use the form of [tex]ax^{2} +bx+c[/tex] to find the values of a, b, and c.

    a = 2, b = 12, c = 18

    Substitute the values of a and b into the formula [tex]d=\frac{b}{2a}[/tex]

    [tex]d=\frac{12}{2(2)}[/tex]

    Simplify the bottom.

    d = 3

    Find the value of e using the formula e = [tex]c-\frac{b^2}{4a}[/tex]

    Raise 12 to the power of 2

    [tex]e=18-\frac{144}{4(2)}[/tex]

    Multiply 4 by 2.

    [tex]e=18-\frac{144}{8}[/tex]

    Divide 144 by 8.

    [tex]e=18-1[/tex] · 18

    Multiply [tex]-1[/tex] by 8.

    [tex]e = 18-18[/tex]

    Subtract 18 from 18.

    e = 0

    Substitute the values of a, d, and e into the vertex form [tex]a(x+d)^2+e[/tex].

    [tex]2(y+3)^2+0[/tex]

    Set x equal to the new right side.

    [tex]x=2(y+3)^2+0[/tex]

    Use the vertex form, [tex]x=a(y-k)^2+h[/tex], to determine the values of a h & k.

    a = 2

    h = 0

    k = [tex]-3[/tex]

    Find the vertex [tex](h,k)[/tex]

    [tex](0,-3)[/tex]

Answer:

16k^2 + 62k + 21

Step-by-step explanation:

We can distribute:

(8k + 3)(2k + 7)

(8k)(2k) + (8k)7 + 3(2k) + 3(7)

Now, we can simplify:

16k^2 + 56k + 6k + 21

16k^2 + 62k + 21

Answer:

a. 4 marks b. 9 questions

Step-by-step explanation:

a) Anu gets 8 correct answer and 12 incorrect answers what is her score?

Since Anu got 8 correct answer and 12 incorrect answers, and + 5 marks is given for every correct answer and (-3) marks are given for every incorrect answer, the total score for correct answers is number of correct answer × marks for correct answer = 8 × (+ 5) = 40.

Also,  the total score for incorrect answers is number of incorrect answer × marks for incorrect answer = 12 × (- 3) = -36.

Anu's total score = total score for correct answers + total score for incorrect answers = 40 + (-36) = 40 - 36 = 4 marks.

So, Anu scored 4 marks.

b) Sam answered all the questions and scored 28 marks though he got 11 correct answers.  How many incorrect answers had he attempted?

Let x be the number of incorrect answers. Since the marks for incorrect answers is -3, then his total score for incorrect answers is -3x.

Since Sam got 11 correct answers and is given + 5 marks for each correct answer, then his total score for correct answers is 11 × (+5) = +55.

Since he gets a total of 28 marks, we have that total score for incorrect answer + total score for correct answer = 28.

So, -3x + 55 = 28

Solving for x, we have

-3x = 28 - 55

-3x = -27

x = -27/-3

x = 9

Since x = 9, Sam attempted 9 incorrect questions.

He or she attempted 9 incorrect answers

Answer:

[tex]x=\frac{3}{5}[/tex]

x = - 1

Step-by-step explanation:

5x² + 2x - 3 = 0

5x² + 2x - 3x = 0

(5x² + 5x) + (- 3x - 3) = 0

5x(x + 1) - 3(x + 1) = 0

(5x - 3)(x + 1) = 0

Create separate equations.

5x - 3 = 0

x + 1 = 0

5x - 3 = 0

5x - 3 + 3 = 0 + 3

5x = 3

5x ÷ 5 = 3 ÷ 5

[tex]x=\frac{3}{5}[/tex]

x + 1 = 0

x + 1 - 1 = 0 - 1

x = - 1

Answer:

C) 12√2

Step-by-step explanation:

According to the 45-45-90 triangle x should be a√2 and since a = 12 (in this case) the answer is 12√2.

Answer:

Option 3 is your correct answer.

I don't see the grid? did you attach a photo?

Answer:

2.40

Step-by-step explanation:

From the triangle QRS

RQ is the hypotenuse 13

QS is the opposite = 12

SR is the adjacent = 5

According to SOH CAH TOA

tan <R =  opp/adj

Tan <R = qs/sr

Tan <R = 12/5

Tan <R  = 2.40

Answer:

Step-by-step explanation:

This factors using a perfect square trinomial. You can recognize this by several characteristics. First off, the leading coefficient is a perfect square (25); second, the constant is also a perfect square (4). Third, the second sign is a + which means that both the signs inside the parenthesis are the same and they are both whatever the first sign is, - . Factoring this then, is the (square root of the leading coefficient times x - square root of the constant):

(5x - 2)(5x - 2) which simplifies down to

[tex](5x-2)^2[/tex], choice A.

Answer: Unlock code = 76

==========================================================

Explanation:

Use a factor tree to find the prime factorization of each value

22 = 2*11

30 = 2*3*5

Both values have '2' in common and this is the largest such value. Therefore, the GCF of 22 and 30 is 2.

So E = 2

----------------------------

Since 3 and 8 have no factors in common (other than 1), this means the LCM is 3*8 = 24

We can say that F = 24.

If the numbers had some larger number in common, then we'd have to do a bit more work to find the LCM.

----------------------------

As the hint suggests, we'll use the distributive property to show that

3*(7+10) = G + 30

3*7 + 3*10 = G + 30

21 + 30 = G + 30

21 = G .... subtract 30 from both sides; they cancel and go away

G = 21

----------------------------

Use the same idea for the other equation as well

5*(3 + H) = 15 + 45

5*3 + 5*H = 15 + 45

15 + 5H = 45

5H = 45 ............ subtract 15 from both sides; they go away

H = 45/5 ......... divide both sides by 5

H = 9

------------------------------

The unlock code is

E+F+G+H = 2+24+21+29 = 76

Answer:

Step-by-step explanation:

angle 4 is congruent to angle 4 because they are alternate interior angles.

angle 5 is congruent to angle 3 because they are alternate interior angles.

angle 1+angle 2+angle 3 is equal to (=) angle 1+angle 2+angle 3

angle 1+angle 2+angle 3=180 degree(being sum of interior angles of a trianngle)
