The y intercept is (0,- 5/2) bestie
From the second equation ,we can know that y=3.25x+0.75
plug it into the first equation
-4.5x-2(3.25x+0.75)=-12.5
-4.5x-6.5x-1.5=-12.5
-11x=-11
x=1
plug it back into the second equation, y=3.25x+0.75=4
the answer would be (1,4)
Answer:
7pi or ≈21.98 cm²
Step-by-step explanation:
The area of the shaded and non shaded in the circle is pir^2 so pi3^2 so 9pi
the area of the 2 smaller circles is pi1^2*2 so 2pi
9pi-2pi=
7pi cm² =
7pi≈21.98 cm² (with pi as 3.14)
Answer:
replace the value of x but x cannot be 0 or a negative number
Step-by-step explanation:
for example:
replace x with 1===> y will be =0 cuz ln(1) = 0
replace x with 2==> y will be = 0.7 cuz ln(2)= 0.7
replace x with 3==> y will be = 1.1 cuz ln(3)= 1.1
replace x with 4==> y will be = 1.4 cuz ln(4)= 1.4
but the graph of ln(x) is famous
check it on the web
Just simply multiply and then add'
15*.05= .75 so .75 was added to the price
now add
.75+15= 15.75
So the answer is $15.75
