Answer:
(2,-2)
Step-by-step explanation:
To solve this using substitution you would take your second equation and plug it in for y of the first equation (4x-10= -3x+4). You then would add the 10 over (4x= -3+14). Next you add the 3x over(7x=14). Finally divide both sides by 7, which should give you x=2. Now all you have to do is plug the two in for x in one of your equations (which ever equation you prefer) (y=-3(2)+4). Solve the equation and you will then have the answer to y, which you can then put into a point.
Answer:
point D
Step-by-step explanation:
think about it....y = x.....this is saying that x and y are equal
now look at point D. (-3,-3)...x = -3 and y = -3
therefore, y = x
the rest of them dont work
because on A, 1 does not equal -1
because on B, 4 does not equal 2
because on C, -3 does not equal 3
Answer:
480
Step-by-step explanation:
In 50 student's play station is owned by =15 student's
∴ In 1 student play station is owned by =15÷50 student
∴In 1600 student's play station is owned by =(1600×15)÷50 student's
=480 student's
∴The number of the student at the high school who
own a Play station is 480
(Ans)
Recall the formula for area of a rectangle
A = LW
A = area of rectangle
L = length of rectangle = 6
W = width of rectangle
Also, recall the formula for Perimeter of a rectangle
P = 2L + 2W
P = perimeter of rectangle = 20
We have L=6 and P=20. Use these to solve for W in the perimeter formula.
P = 2L + 2W
20 = 2(6) + 2W
20 = 12 + 2W
8 = 2W
4 = W
Thus, L = 6 and W = 4. Use these measurements to solve for A.
A = LW = 6 * 4 = 24 in^2
