Step-by-step explanation:
<h3>Given</h3>
<u>Ordered pairs </u>
- (12, 6), (3, 1), (2,-2), (5, 10), (-8, -4) (_,_)
<h3>To find</h3>
<h3>Solution</h3>
Since it is a function, the missing pair can't repeat input values with different output, therefore only option D is unique so is the correct choice
Answer: 79.2
Explanation: 110% as a decimal is 1.10
1.10 x 72=79.2
Answer:
Each daylilies cost $7
Step-by-step explanation:
Step one:
let roses be x
and daylilies be y
so
8x+15y=193--------------1
also
3x+12y=117--------------2
we can solve equations 1 and 2 by substitution
8x=193-15y
x=(193-15y)/8
put x= (193-15y)/8 in 3x+12y=117
3((193-15y)/8)+12y=117
(579-45y)/8+12y=117
579-45y=8(117-12y)
579-45y=936-96y
collect like terms
579-936=-96y+45y
-357=-51y
divide both sides by -51
y=-357/-51
y=7
Hence each daylilies cost $7
put y=7 in eqn 1
8x+15(7)=193
8x+105=193
8x=193-105
8x=88
x=88/8
x=11
rose cost $8
It's B
Slope is negative, the other must be positive due to m1 x m2 = - 1
m1 = -2/5
The diagram shows a gradient of -2/5. So, the
reciprocal of this valve to make - 1 is 5/2 (which is the - 2/5 flipped upside down, but positive)
-2/5 x 5/2 = - 10/10 (or - 1)
Thus, the perpendicular line to this has a gradient of 5/2.
Hope this helps!
Answer:
Daniel is charged $900
Step-by-step explanation:
This is because 9 percent of 5000 is 450. Multiply 450x2 and get 900.
