Paralalell means that is has the same slope
y=mx+b
m=slope
y=-1x-2
slope=-1
the equation of a line that passes through the point (x1,y1) and has a slope of m is y-y1=m(x-x1)
given
(2,-2) and slope is -1
y-(-2)=-1(x-2)
y+2=-x+2
minus 2
y=-x
answer is y=-x
39x98 is 3,822. do you need to know how I got that?
Given:
A rectangular greeting card uses a geometric design containing 4 congruent kites.
Consider the below figure attached with this question.
Length of card = 8 inches
Width of card = 4 inches
To find:
The area of one kite.
Solution:
The kites are connected to each other as shown below.
The length of a kite is:
inches
The width of a kite is:
inches
Area of a kite is:
Where, are diagonals of the kite.
Length and width of a kite are 4 inches and 2 inches respectively. So, the diagonals of a kite are 4 inches and 2 inches.
Using the above formula, we get
The area of a kite is 4 sq. in.
Therefore, the correct option is A.
Answer: door hinges<$4.69
Step-by-step explanation: From the question, we can deduce that
1. Jonah has just $50 and can’t spend beyond it, so his total budget must be less than or equal to $50
2. Jonah will spend a total of $12.54 (add all the items with known prices),
leaving him with $37.46(50-12.54) to spend on 8 door hinges.
Therefore 8x<=37.46(8x has to be less than or equal to $37.46)
x=door hinges
Hence, x<=4.6825 (divide both sides by 8)
But we wouldn’t spend such fraction, lol, so we’ll approximate to the nearest cent.
x<4.69 ( I chose the higher number and removed the equal sign)
OR x<=4.68
