Answer:

y = 0

x = -8

Step-by-step explanation:

1/2x + y = - 4

y = 2x + 16

1/2x + (2x + 16) = - 4

1/2x + 2x = - 4 - 16

5/2x = -20

2/5 x 5/2x = -20 x 2/5

x = -40/5

x = -8

y = 2x + 16

y = 2(-8) + 16

y = -16 + 16

y = 0

Check:

1/2x + y = - 4

y = 2x + 16

1/2(-8) + (0) = -4

-4 + 0 = -4

-4 = -4

y = 2x + 16

(0) = 2(-8) + 16

0 = -16 + 16

0 = 0

Answer:

39/10

Step-by-step explanation:

Answer:

39/10

Step-by-step explanation:

to make 3 9/10 an improper fraction all you have to do is take the whole number-3 and take the denominator-10 and multiply them 3 x 10 = 30, then add it to the numerator 9 + 30 equals 39 this is your new numerator

Answer:

Perimeter = 50 inches

Step-by-step explanation:

Use pythagoreon theorem to find the hypotenuse

a^2 + b^2 = c^2

3^2 + 4^2 = 5^2

9 + 16 + 25 = perimeter

perimeter = 50

Answer: 74 degrees Fahrenheit  

Step-by-step explanation: the temperature outside was 13 degrees lower than 87 degrees, so  87 - 13 = 74

Answer:

74 degrees F

Step-by-step explanation:

Subtract the 87 - 13

This is because there are +13 degrees more than outside. So if you add 74 + 13 that were added by the thermostat, you get 87 degrees. Does it make sense?

Just subtract :)

1= 1/8

3= 2/8

Step-by-step explanation:

Answer:

x = 2

y = 1/2

Step-by-step explanation:

3x - 2y = 5

x + 2y = 3

We don't have to mutiply anything because we have values that we can eliminate.-2y and 2y can be crossed off becuase they have the same value and plus and minus cancel out. We can add instead of changing the signs.

4x = 8

x = 2

Now we know that x = 2. To find y we have to plug in x into one of the equations. I am going to use x + 2y = 3.

2 + 2y = 3

2y = 1

y = 1/2

Now we figured out y. I hope I helped!

Answer:

D. 64 (cos(pi)+isin(pi))

Step-by-step explanation:

Put 2+2i into trigonometric form, raise the r value to the power of 4, and multiply the angle value (theta) by 4 to get the equation of z^4. In this case, r was 2(sqrt2), which raised to the 4th power was 64. The angle value was pi/4, which multiplied by 4 was pi. That's how we get the answer:

64 (cos(pi)+isin(pi)). How this helps!

Following are the calculation to the given value:

Given:

[tex]\to Z= 2+2i[/tex]

To find:

[tex]Z^4=?[/tex]

Solution:

[tex]\to Z= 2+2i[/tex]

[tex]\therefore\\\\i^2= -1[/tex]

[tex](a+b)^2= a^2+b^2+2ab[/tex]

Square the given value:

[tex]\to Z^2= (2+2i)^2[/tex]

         [tex]= 2^2+(2i)^2+2 \times 2 \times 2i\\\\= 4+4i^2+8i\\\\= 4-4+8i\\\\=8i[/tex]

When [tex]Z^2= 8i[/tex] then again square the value

[tex]\to ( Z^2)^2= (8i)^2\\\\\to Z^4= 64i^2\\\\\to Z^4= -64\\\\[/tex]

Therefore, the final answer is "-64".

Answer:

The value of x is 25

Step-by-step explanation:

In the given figure

→ In circle O

∵ GB and GD intersect it at points F, B, and E, D

∴ GB and GD are secants of circle O

∵ GB and GD intersect outside the circle O at point G

∵ They intercepted arcs EF and BD

→ By using the rule above

∴ m∠G = [tex]\frac{1}{2}[/tex] (m arc BD - m arc EF)

∵ m arc BD = m arc BC + m arc CD

∵ m arc BC = 35° and m arc CD = 100°

∴ m arc BD = 35 + 100 = 135°

∵ m arc EF = x

∵ m∠G = 55°

→ Substitute them in the rule above

∴ 55 = [tex]\frac{1}{2}[/tex] (135 - x)

→ Multiply both sides by 2 to cancel the fraction [tex]\frac{1}{2}[/tex]

∵ 110 = 135 - x

→ Subtract 135 from both sides

∴ -25 = -x

→ Divide both sides by -1

∴ 25 = x

∴ The value of x is 25

=8 gold coins

Step-by-step explanation:

The required number of gold coins he needs is given 8 coins.

Given that,
Collin is playing a video game. He wins 25 points for each gold coin he finds. His goal is to win more than 200 points.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
1 coin = 25 points
For 200 points number of coins is given as = 200 / 25 = 8 coins

Answer: x= 108

Step-by-step explanation: The triangle is an isosceles triangle, so the two sides are parallel which means the other angle equals to 72 as well. Now we take the triangle rule and do 180-72-72= 36 (the top angle= 36). The triangles are all equal so that means the other angle (in the upside down one) also equals 72 so we take 36+72= 108. Since it is also a parallelogram, the angles are equal.
