(-7,-5)
Step-by-step explanation:
3x-8y = 19
minus
3x + 5y = -46
0x - 13y = 65
- 13y = 65
÷-13
y = - 5
Substitute y = - 5 into one of the functions:
3x-8y = 19
-8 x - 5 = 40
3x + 40 =19
-40
3x. = - 21
÷3
x= - 7
Solution is (-7,-5)

rDistance (D) = Speed (S) * Time (T)
S * T = r*20/60 mins = r / 3
So r/3
Answer:
Click the 'x' on the top of the tab
Step-by-step explanation:
Move your coursor to the 'x' and click.
We can see the ratio of a side big figure and small figure is 60:15 or 60/15 = 1/4.
In decimal form we can write 1/4 as 0.25.
Therefore, scale factor is 0.25.
So, second option is applicable. Please check second option :
<h3>The scale factor is 0.25.</h3>
Now, let us find the side A by multiplying by scale factor 0.25 of the big figure.
The corresponding side of A is 35.
Therefore, A is 0.25 × 35 = 8.75 cm.
Therefore, other applicable option is 3rd option.
<h3>The length of side A is 8.75 cm.</h3>
