Answer:
(1, 5), (3, 19) (-1, -9)
Step-by-step explanation:
really need the choices
7/8-5/8= 2/8 and if you reduce 2/8 by 2 it becomes 1/4. So 1/4 is your answer. Hope This Helps :D
Answer:
20, increased, Bianca
Step-by-step explanation:
First one:
He is shown to have travelled 20km in 1 hour, so that's 20km/h.
Second:
The gradient is how steep the curve is, the steeper the faster the person is travelling. Due to the fact Bianca's curve becomes steeper, it shows she is travelling faster. Therefore, her running speed increases.
Third:
Bianca's line hits 50km before Alberto, so therefore she finished first.
Let me know if this makes sense, hope it helped! :D
<h2>
Answer: (5, 2)</h2>
<h2>
System of equations:</h2>
2x - y = 8
3x + y = 17
<h2>Solve for x:</h2>
2x - y = 8
3x + y = 17
________ +
5x = 25
x = 5
<h2>Plug in x to one of the equations to solve for Y</h2>
2(5) - y = 8
10 - y = 8
-y = -2
y = 2
