The slope is 3 because you need to use the slope-intercept form y=mx+b to find the slope of m
Answer:
left 4 up one because the coordinates are -4 , 1
Answer:
A = 21 cm²
Step-by-step explanation:
The area (A) of a trapezium is calculated as
A = 
h (b₁ + b₂ )
where h is the height between bases and b₁, b₂ are the parallel bases
Here h = 3, b₁ = 9, b₂ = 5 , then
A = × 3 × (9 + 5) = 1.5 × 14 = 21 cm²
Answer:
No
Step-by-step explanation:
22 - 6x = 15
subtract 22 from both sides
-6x = -7
divide both sides by -6
x = 7/6 or 1 1/6
Hello,
We can set up two equations and solve the problem.
Let x be Crocus and y be daffodil. So:
x+y=40
.45x+.65y=20.40
Multiply the first equation by -.45 so to eliminate x. So we get:
-.45x-.45y=-18 Now add this to the second equation:
+.45x+.65y=20.40
And we get:
.20y=2.40 Divide each side by .25 to get:
y=12 Now we can find x by plugging 12 for y in the first equation:
x+12=40 Subtract 12 from both sides to get:
x=28
So now we know there are 12 daffodil and 28 crocus.
