The variable y is given.
now, substitute y in the second equation to get
-4x - (-4x-7) = 7
then we solve
first distribute
-4x+4x+7=7
combine like terms
0+7 = 7
7 = 7
because the answer is true, the solution to this system is “all real numbers”
All you have to do is put 14 over 120 and divide. So 14/120 will become 0.11666666666 in decimal form. To round to the nearest thousandth, just count 3 places from the decimal point and look at the number to the right. If it is higher than 5, add one the 3rd number from the decimal, but if it is not, then just keep it the same. So, in this case it would be 0.117
Answer:
Figure 1
Step-by-step explanation:
Congruent shapes are shapes that share the same side lengths and angle measures. In figure 1, we see that all sides and angles are marked equal, thus both shapes are congruent. However, in figure 2, we clearly see that the sides of each of the triangles are different. Thus, the triangles in figure 2 are not congruent.
Answer:
2nd one
Step-by-step explanation:
(x*x*x*x*x*x*x*x*x)
or x^9
Answer:
The points are collinear if the slope of any two pair of points is the same. Many infinite planes pass through that line. Thus, there are infinite planes contain the same three collinear plane.
