ANSWER
1a)
The given system of equation is:
and
We make x the subject in equation (2) to get;
We put equation (3) into equation (1) to get;
We expand the bracket to get,
This implies that,
This statement is false.
Hence the system has no solution.
1b)
Let us write the two systems in the slope-intercept form;
For the first equation, we have
Thus implies that,
For the second equation, we have:
We can see that, the two equations are parallel since they have the same slope.
Also the two equations will never meet since they have different y-intercepts.
Hence the system has no solution.
The answer for question two is: 8x(3,000+200+9)
Hope this helps!
The two figures are similar because they are the same shape, but one is more dilated than the other.
Answer: (23.25- 17.25) divided by 2
(Sorry I don’t have a division sign)
Answer:
Step-by-step explanation:
To work out the volume of this shape you will first need to work out the area of the triangle. To work out the area of the triangle you would multiply the base of 12 by the height of 4.1, which gives you 49.2. You would then need to divide 49.2 by 2, which gives you 24.6. This is because the formula for the area of a triangle is the same as that of a square, however a triangle is half of a square with the same length and width. To work out the volume you would multiply the area of the triangle, which is 24.6 by the height of 9, which gives you 221.4
1) Multiply 12 by 4.1.
2) Divide 49.2 by 2.
3) Multiply 24.6 by 9.
