Answer:
Both drop-down answers are 0
Step-by-step explanation:
You are just replacing the x with a 0.
ALSO: The question at the top: Yes 2x + 6x is equivalent to 9x in this equation, because multiplying anything times 0 equals 0, so it doesn't matter what number comes before the x, it will always equal 0.
So when x = 0: 2x + 6x = 0, and 9x = 0, they are equivelant.
Answer:
Step 1: Calculate
We calculate the square root of 23 to be:
√23 = 4.79583152331272
Step 2: Reduce
Reduce the tail of the answer above to two numbers after the decimal point:
4.79
Step 3: Round
Round 4.79 so you only have one digit after the decimal point to get the answer:
4.8
To check that the answer is correct, use your calculator to confirm that 4.82 is about 23.
Horizontal Line at the coordinates:
(0, 1)
Slope Intercept:
y = mx + b
y = 0x + 1
The graph has no rise.
Answer:
Step-by-step explanation:
In the first triangle, you have the following relation between a, b and h.
This is another form of the Altitude Theorem in a right triangle.
In the second example, we use the Altitude Theorem:
Let h denote the dotted line / the altitude;
h = 6, we take the positive version since we're in Euclidean Geometry.
Now we have to solve for x. It's easy since the h that we solved for is in a right triangle and we have Pythagora's Theorem for that.
It states:
So
Answer:
b = (c-3a)/2
Step-by-step explanation:
3a+2b =c
Subtract 3a from each side
3a-3a+2b =c-3a
2b = c -3a
Divide each side by 2
2b/2 = (c-3a)/2
b = (c-3a)/2
