I think that it the secound one then the fourth one then the sixth one then the first one then the fifth one then third one the eighth one then the ninth one
The perimeter is solved by using the formula:
P = 2 l + 2 w
where l is the length of one side = 15 inches, and w is
width of one side = 1 ¾ ft = 21 inches
P = 2 (15 inches) + 2 (21 inches)
P = 72 inches
We know that there are 36 inches in 1 yard therefore:
P = 72 inches * (1 yard / 36 inches)
<span>P = 2 yards</span>
Answer:
3.6 and 8.4
Step-by-step explanation:
you put it into proportions
?/12= 30/100
you do 30 times 12
then divide it by 100
?/12 = 70/100
multiply 70 and 12
then divide it by 100
Answer:
a) .
Substitute all the values in the given relation.
The steps and table is attached below.
b) The relation is not a function.
Since the x =0 and x=3 has the same value. A relation is function when each input has only exact one output. refer the on-to diagram uploaded.
c) The domain is the set of all input values that can be applied into a function y or f(x).
Here all the x values -4,-3,-,-1,0,1,2,3,4 [-4,4] is the domain.
Answer:
Please check the formatting when posting. I'm assuming these are the equations:
y=x^2 - 2
y=−x
Step-by-step explanation:
We can either graph the equations or solve them. I use graphing - see the attachment. The lines intersect at (-2, 2) and (1,-1)
<u>1. Graphing</u>
See attached graph
(-2, 2) and (1,-1) are the intersection points
<u>2. Solving</u>
y=x^2 - 2 Use y=−x in this equation:
-x = x^2 - 2
0 = x^2 + x - 2
0 = (x+2)(x-1)
x = -2 and +1
(-2, 2) and (1,-1) are the intersection points
