Answer:
(-5, -30)
Step-by-step explanation:
We start with the equation:
y = 6x
y = -4x - 50
Since both of them are equal to y, we can substitute the 6x into y. So:
6x = -4x - 50
Now we can solve for x. Add 4x to both sides...
6x = -4x - 50
+4x +4x
10x = -50
Now, divide both sides by 10.
<u>10x</u> = <u>-50</u>
10 10
x = -5
So, we now know that x is -5. Now we know this, we can substitute -5 where we see x. It works in both equations, so I will do both.
y = 6(-5)
y = -30
And...
y = -4(-5) - 50
y = 20 - 50
y = -30
As you can see, both equations show that y = -30. To check our work, let's plug in the values.
-30 = 6(-5)
-30 = -30
Also:
-30 = -4(-5) - 50
-30 = -20 - 50
-30 = -30
So, we can see that both of the equations gave us the same answer. So, our answer is x = -5 and y = -30, so the ordered pair is: (-5, -30). Hope this helps you!
Answer: 502.65
Step-by-step explanation: A= 2πrh + 2πr^ this is the formula for solving the surface area so now you must substitute
2·π·5·11+2·π·5^
6.28 · 55 + 2 π · 25
add and you will get 502.65 hope this helps mark me brainliest if it did
<em> 195 yards²</em>
- Step-by-step explanation:
<em><u>Area of rhombus (formula)</u></em>
<em>A = (d₁ₓd₂)/2</em>
<em>d₁ = 2ₓ7,5yd = 15 yd</em>
<em>d₂ = 2ₓ13yd = 26 yd</em>
<em>A = (15ydₓ26yd)/2</em>
<em>= 15ydₓ13yd</em>
<em>= 195 yards²</em>
Answer:
125%
Step-by-step explanation:
15/12 = 1.25 then you move the decimal over 2 places.
