can you help me?????
Answer:
Step-by-step explanation:
I don't do this question the way it is outlined. My way is a bit shorter.
The general equation is y = mx + b
You want the slope to be - 1/5 which you just read from the given equation.
So, so far you have y = -1/5x + b
Now for the point which is (5,-4)
x = 5
y = - 4
-4 = -1/5 * 5 + b
-4 = -1 + b
b = -4 + 1
b = - 3
the equation is y = -1/5 x - 3
===========================
Now let's do it your way.
y - y1 = m(x - x1)
x1 = 5
y1 = - 4
m = - 1/5
y - - 4 = -1/5(x - 5
y + 4 = -1/5x + 1 Take 4 from both sides
y = -1/5 x + 1 - 4
y = -1/5 x - 3
Same answer. I never knew that was possible.
What is the value of A shown in the equation?
7 x 9 = (1 x 10)-(7 x A)
Answer:
A= -53/7
Step-by-step explanation:
1 x 10 -1 x 7 x A=7 x 9
10-7A =7 X 9
10-7A=63
-10 -10
-7A=53
A= -53/7
7. Simplify the expression
Answer:
11x
Step-by-step explanation:
find what times itself gets 64 thats 8 so 64=8 now do the same to the 9=3 now you add 8+3=11 just add x
3 - 2(b - 2) = 2 - 7b
b =

What is the surface area if this sphere?
Answer:
The surface area of the sphere is approximately equal to 379.9 square centimetres.
Step-by-step explanation:
The surface are a of a sphere with respect to radius is 4πr². We're given the diameter, of 11 cm, so we know that the radius is 5.5 cm.
With that we can find the surface area:
[tex]a = 4\pi r^2\\a = 4\pi (5.5cm)^2\\a = 4\pi \times 30.25cm^2\\a = \pi \times 121cm^2\\a \approx 3.14 \times 121cm^2\\a \approx 379.9cm^2[/tex]
