Answer:
the answer is B
f(x)=-2x+3
Step-by-step explanation:
to get the -2x I did --->
pick two points I used (0,3) and (1,1) and used the equation
where y2 would be 1 and y1 would be 3
and where x2 would be 1 and x1 would be 0
so you would put the numbers in the equation which would look like and equal -2 which would be -2x in the answer
And the +3 is the y-intercept

Answer:
Step-by-step explanation:
The width of the rectangle = x
Therefore the length of the rectangle = 2x, as it is twice its width
We know that the perimeter of a rectangle = 2 × (length + width)
So since the perimeter equals to 30, then we can form the equation:
2×(2x+x) = 30
2×(3x) = 30
6x = 30
x = 5
width of the rectangle = x = 5
length of the rectangle = 2x = 2×5 = 10
If there is an unit which is in the question, remember to add it to the end of the answer. As you have not written any units in the posted question, I will leave it as it is.
Hope this helps :)
Answer:
x=3 and y=4
Step-by-step explanation:
The opposite sides of a parallelogram are congruent, or equal.
Therefore, (4x+6) = (7x-3) and (4y-3) = (3y+1)
4x+6 = 7x-3 –– Subtract 4x from both sides
6=3x-3 –– Add 3 to both sides
9=3x –– Divide both sides by 3 to get x alone
3=x
4y-3 = 3y+1 –– Subtract 3y from both sides
y-3=1 –– Add 3 to both sides
y=4
Check by substituting:
4(3)+6 = 7(3)-3
12+6 = 21-3
18 = 18
4(4)-3 = 3(4)+1
16-3 = 12+1
13 = 13
