3x+2y=11--------x1
7x-y=3------------x2
3x+2y=11---equ 1
14x-2y=6---equ 2
equ 1+ equ 2 will eliminate y
17x=17
x=1
then put x=1 in equ 1
3(1)+2y=11
2y=11-3
2y=8
y=8/2
y=4
Answer:
4
Step-by-step explanation:
D (-1, -3) and F( 2, 3)
G (-4, -4)
Which point on the y-axis lies on the line that passes through point G and is parallel to line DF?
If the line is parallel to DF then they have the same slope.
slope of line DF is m= difference in y/ difference in x = (-3-3)/( -1-2) = -6/-3 = 2
so slope of line that passes trough G and is ║ with DF is also m= 2
From point G (-4, -4) we go with a slope of 2 until we get to the y-axis
So we go up 2 and 1 left, 2up and 1 left, ... until we get to the point (0, 4), because the slope = rise/run = rise 2/run 1
Answer:
A) Number line from negative 10 to positive 10 in increments of 1 is shown. Only the whole numbers are labeled. A solid blue point is placed on the 3rd tick mark to the left of 0. A solid, blue point is on the 3rd tick mark to the right of 0.
Step-by-step explanation:
Consider the provided number -3.
We need to determine the number line which shows the opposite of -3.
The Opposite numbers are numbers that are precisely the same length from 0, but on opposite sides, when put on a number line.
The opposite numbers are the same number except their sign.
The opposite number of -3 is 3.
The required number line is shown below:
Hence, the correct option is A) Number line from negative 10 to positive 10 in increments of 1 is shown. Only the whole numbers are labeled. A solid blue point is placed on the 3rd tick mark to the left of 0. A solid, blue point is on the 3rd tick mark to the right of 0.
