Answer:

x = 4

Step-by-step explanation:

Given

2x² - 7x - 4

To solve for x , equate the expression to zero

2x² - 7x - 4 = 0 ← in standard form

(x - 4)(2x + 1) = 0 ← in factored form

Equate each factor to zero and solve for x

x - 4 = 0 ⇒ x = 4

2x + 1 = 0 ⇒ 2x = - 1 ⇒ x = - [tex]\frac{1}{2}[/tex]

Thus the positive value of x is x = 4

Answer:

x=4

Answer:

Given that Amadahy has a $ 20 bill, and wants to buy a card and two gifts for her friend, and knowing that each card costs $ 3.49 and each gift costs $ 10.63, the total cost of the 3 items would be $ 24.75 (10.63 x 2 + 3.49 ).

Therefore, she will not be able to purchase the products she wants, since she will need $ 4.75 to reach the amount necessary for it (24.75 - 20).

Answer:

∠ QPM = 68°

Step-by-step explanation:

The measure of the chord- chord angle QPM is half the sum of the arcs intercepted by the angle and its vertical angle, that is

∠ QPM = [tex]\frac{1}{2}[/tex] ( LM + LK )

            = [tex]\frac{1}{2}[/tex] ( 76 + 60)°

           = [tex]\frac{1}{2}[/tex] × 136°

           = 68°

Answer:

$18.15

Step-by-step explanation:

Here, we want to find the difference between the two values

what we do here simply is to subtract the second from the first

Mathematically we have this as;

36-17.85 = $18.15

Answer: He is Incorrect, It's 38

Work: For this question, I did the Cross-Product Method. The Cross Product Method is when you solve equation via to fractions. With the CPM, One one side of the fraction, I had x / 20 (Twenty being the whole number) and on the other side, I had 190/100 (190 being the percent) After setting this up, I made the equation. 190 times 20 is 3800, and the other multiplication is 100 times x which is 100x. So, the new equation is 3800 = 100x. I divided both sides by 100, and the answer is 38 = x

I hope this helps, and Happy Holidays! :)

Answer:

No, Marcus is not correct. He converted the percent to a decimal correctly and he multiplied correctly, but he put the decimal in the wrong place in the answer. There should be two decimal places in the answer, so the answer should be 38.

Answer:

0.75

Step-by-step explanation:

From the attached question, we

3÷ 4

We are asked to find 3÷ 4

3 ÷ 4 = 3/4

We simplify further in other to get a decimal form

3/4 = 0.75

Answer:

x=8°

y=29°

Step-by-step explanation:

vertically opposite angles are equal

so 5x+9°=y+20°

therefore 5x-y=11°

Alternate angles are equal

so 4x+17°=y+20°

therefore 4x-y=3°

equation 1....... 5x-y=11°

equation 2......4x-y=3°

using elimination method x=8°

y=29°

Answer: a

Step-by-step explanation: edge 2020

Answer/Step-by-step explanation:

9. 17x = 16x + 5 (alternate exterior angle)

17x - 16x = 5

x = 5

Measure of bolded angle = 17x = 17 * 5 = 85

10. 21x - 6 = 20x (corresponding angels)

21x - 20x = 6

x = 6

Measure of bolded angle = 20x = 20(6) = 120

11. (x + 95) + (x + 105) = 180 (linear pair angles)

2x + 200 = 180

2x = 180 - 200

2x = -20

Divide both sides by 2

x = -10

Measure of bolded angle = x + 105 = -17 + 105 = 88°

12. 12x - 4 = 11x + 3 (vertical angles)

Collect like terms

12x - 11x = 4 + 3

x = 7

Measure of bolded angle = 11x + 3 = 77 + 3 = 80°

Answer:

[tex]\huge\boxed{\sf Star = 14}[/tex]

Step-by-step explanation:

Let snowman be x , star be y and shopping bag be z.

So, the given equations are:

1) x + y = 20                 (Eq. 1)

2) z = x + x      

 z = 2x                         (Eq. 2)

3) z + x = 18                   (Eq. 3)

Put Eq. (2) in Eq. (3)

2x + x = 18

3x = 18

Divide both sides by 3

x = 18 / 3

x = snowman = 6

Now, Put x in (Eq. 1)

6 + y = 20

Subtract 6 to both sides

y = 20 - 6

y = 14

So,

Star = 14

Answer:

(x,y) = (-36,6)

Step-by-step explanation:

-6y=x

x+y=-30

x=-6y,

so -6y+y=-30

-5y=-30

y=6

x=-36

Hope this helps pls hit the crown :D

Answer:

30 ÷ 6 =5 so

5 is to the power 6

The solution for your question is-1/6

Answer:

- 1/6

Step-by-step explanation:

Use the following equation to calculate slope between two points:

( Y2 - Y1 ) / ( X2 - X1 )

What's Y2? Y1? X2? X1?

( -1, 6 )

-1 = X1

6 = Y1

( 5, 5 )

5 = X2

5 = Y2

So when we plug in those numbers:

5 - 6 = - 1

5 - (-1) = 6

- 1/6

Answer:

B. The deposit increases by 3% of its current value, compounded monthly.

Step-by-step explanation:

When compounded monthly that means the account is getting more money monthly rather than annually, or each year, so this answer choice would give the best benefit to the account holder. I did this problem on Khan Academy myself and this was the correct answer.

Step-by-step explanation:

Answer:

x = 12 and y = 16

Step-by-step explanation:

Given the following lengths;

NO = x + 2y,

MO = 3x,

PQ = 6x + 4, and

OQ = 2y + 4.

The following postulates are true;

MN = PQ

Since MO + ON = MN

MN = 3x + x+2y

MN = 4x + 2y

Recall that PQ = 6x+4

Equating both expressions;

4x + 2y=  6x+4

Collect like terms;

4x-6x + 2y = 4

-2x + 2y = 4

x - y = -4 ...... 1

Also MO = OQ

3x =  2y + 4

3x-2y= 4 ....2

from 1; x = -4 + y

Substitute into 2:

3x-2y= 4

3(-4+y)-2y = 4

-12+3y-2y = 4

-12+y = 4

y = 4 + 12

y = 16

Since x = -4+y

x = -4 + 16

x = 12

Hence x = 12 and y = 16

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identity

sin²x + cos²x = 1 , then sin²x = 1 - cos²x

Consider the left side

sin²a - sin²b

= (1 - cos²a) - (1 - cos²b)

= 1 - cos²a - 1 + cos²b

= cos²b - cos²a

= right side , thus verified
