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
<u>Answer:</u>
D
of Y = (-3/2, -1)
<u>Step-by-step explanation:</u>
We are given three points on the graph:
X (4, 0)
Y (3, 2)
Z (2, 2)
and the scale factor of dilation which is 
.
Given that, we are to find the coordinates of Y after dilation. To find that, we will multiply the coordinates of the point Y with the scale factor.
Y = 
× 
, (-\frac{1}{2}[/tex] × 
Y = 
Answer:
x= -11
Step-by-step explanation:
distribute the 3 and the 2: 3 - 9x = -8x + 14
add 9x from both sides and subtract 14 from both sides: -11 = x
x = -11
Step-by-step explanation:
Area of a trapezoid is 1/2h(b1+b2)
Height is 8 in. Base 1 is 5 in and Base 2 is 10 in. Do not use the diagonal side.
For the triangle-scalene triangle area formula is bh/2 (base times height divided by 2) The base is 5 in and the height is 4 inches.
For the paralellogram multiply base by height. 6 multiplied by 5 is 30
You subtract 1.1 each time so the answer is 6.6 (a)
