Answer:
The answer is option C i.e; y=0.9x-45
Step-by-step explanation:
When you substitute the values of x you have to get same values as given in the table
For example: substitute x=50 in the equation y=0.9x-45
Y= 0.9(50)-45
Y= 45-45
Y=0
Step-by-step explanation:
7 - 3b-2(0 + 3 - 2b)
To simplify the expression in the box, Fatua used
these steps:
Step 1:7 - 3b-2(3 - 3b)
Step 2:7 - 3-6-36-
Step 3: -13 - 66
Did Fatua calculate correctly? if nnot, in what step
did she make her FIRST mistake?
Answer:
The area of the sector is 
Step-by-step explanation:
step 1
Find the area of the circle
The area of the circle is equal to

we have
----> the radius is half the diameter
substitute


step 2
Find the area of a sector with a central angle of (2pi/3)
Remember that
The area of
subtends a central angle of 
so
by proportion
Let
x----> the area of the sector

Answer:
4.33 : 6.49
Step-by-step explanation:
Given endpoints as A(-7,-2) and (2,4) find the length of the segment
d=√ (x₂-x₁) + (y₂-y₁)²
d=√ (2--7)² + (4--2)²
d=√ 9² + 6²
d= √ 81 +36
d=√117 =10.82
The partition is at (-3.4,0.4)
The length from A to the partition will be
A(-7,-2) (-3.4,0.4)
√ (-3.4--7)² + (0.4--2)²
√ 3.6²+2.4²
√18.72 = 4.33
Length of segment from partition to end point B
(-3.4,0.4) , B(2,4)
√(2--3.4)²+(4-0.4)²
√ 5.4² + 3.6²
√42.12
=6.49
The ration that results from the partition of the segment is;
4.33 : 6.49
