Answer:
Second option
Step-by-step explanation:
Answer:
Last option
over the interval (-∞, -4)
Step-by-step explanation:
Note that from -∞ to -4 the function F has a positive value, the graph is above the x-axis. So the first statement is false and the last is true.
over the interval (-∞, -4)
Then, from 
the function F is negative. 
. But for 
, .
Therefore the second and third statements are false.
<em>The only true statement is the last option</em>
Y=4 and x=-2 which is (4, -2)
Answer:
Step-by-step explanation:
Since it is an isosceles triangle, 34 = x-5.
x=39 and 4y =180-(34+34)
4y=112
y=28
Answer:
The bag costs 1500, while the umbrella cost 500
Step-by-step explanation:
Let the cost of the bag be b and the cost of the umbrella be u
Total cost is;
b + u = 2,000 •••••(i)
From the second part of the question;
b = 5u-1000 ••••••(ii)
Substitute ii into i
5u-1000 + u = 2000
6u = 2000 + 1000
6u = 3000
u = 3000/6
u = 500
To get b, substitute the value of u into equation ii
b = 5(500)-1000
b = 2500-1000
b = 1500
