Solve the system of equations using elimination.
3x-2y=5
x+2y=3
Answers
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!

The value of x is 25
Step-by-step explanation:
A secant is a line that intersects a circle in exactly two points. When two secants, intersect at a point outside a circle then the measure of the angle formed between them is one-half the positive difference of the measures of the intercepted arcsIn 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

Bianca set the thermostat in her house to 87°F, which was 13° warmer than the temperature outside. What temperature was it outside?
Confused.
Answers
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 :)

Find the value of x
Answers
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.

If Z= 2+2i, what is z^4?
Answers
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".

Answers
1/2x+2x+16=-4 now find x
which is x=8 not plug in -8 for x, does not matter which one
you will get y=0
answer•
x=-8
y=0
(-8,0)
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
