Answer:
I say A or B but in favor A
Step-by-step explanation:
We can do anything to an equation as long as we do it to both sides
given:
square both sides
minus 3 from both sides
multiply both sides by 6
minus 4
square both sides
do for -4+6 and -4-6 (2 and -10)
and
minus 3

x=97 doesn't work
the answer is x=1
The image of PQR is shown in the diagram below
The image of R is (6, -3)
Answer:
y = - 0.8
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition when y = - 4, x = 10, then
- 4 = 10k ( divide both sides by 10 )
- 0.4 = k
y = - 0.4x ← equation of variation
When x = 2 , then
y = - 0.4 × 2 = - 0.8
Step-by-step explanation:
The formula used to find volume of cone is:
Height = 24 inches
Radius = ?
We can find Radius using Pythagoras theorem:
Since radius = diameter / 2
so, radius = 7/2
radius = 3.5
Putting values in the formula:
So,
