Answer:
A. (3,0)
Step-by-step explanation:
When the equations are graphed, the solution is where the two graphs cross. For the red line and the blue line, the cross at (3,0)
We can check this by substituting x=3 into both equations and seeing if we get y=0
y = -x+3
y = -3+3
y =0
y = x-3
y = 3-3
y=0
In both cases, we got y=0.
Therefore (3,0) is a solution to both equations and since it solves both equations, it solves the system.
the answer is x equal 100
The correct question is
A triangle has side lengths of 7 centimeters, 5 centimeters, and c centimeters. enter a value to complete the inequality that describes the possible values for c, the length of the third side of the triangle.
we know that
The sum of the lengths<span> of any two </span>sides<span> of a </span>triangle<span> must be greater than the </span>third side
If c is the smallest number, then
5 + c > 7
c > 2
If c is the largest number, then
5+7 > c
12 > c----------> c < 12
the answer is
The value of c must be in the interval (2,12)

Answer:
D: 21
Step-by-step explanation:
The first term is (a1). The third term is (a1)r². The product of these terms is ...
(a1)(a1)r² = ((a1)r)², the square of the second term.
The missing term is √(7·63) = √441 = 21.
_____
<em>Additional comment</em>
In consideration of the above, you can also see that the common ratio can be found from ...
a3/a1 = ((a1)r²)/(a1) = r² = 63/7 = 9
Then the common ratio is r = √9 = 3, and the second term is 7·3 = 21.
