Hi there!
Since the formula for finding the perimeter of a rectangle is length×2 + width × 2, we can follow this rule.
2 (4x + 5) + 2 (8x - 4)
= 8x + 10 + 16x - 8
= 24x + 2
So, the perimeter is 24x + 2.
Hope this helps!
17% would be 17/100. or 67%=67/100. 46% = 46/100 (simplify!) see the pattern? hope it helps!
So to label the axes the number of people would be on the left and number of forks on the bottom. choosing your scale means how you would choose to count. the independent variable is the forks and dependent is the people. For the scale I would count by 2s for the x-axis and 1s for the y-axis.
The intercept method of graphing is quick and easy.
Find the x-intercept by setting y = 0 and solving for x:
y+1=1/3(x−3) => 0<span>+1=1/3(x−3)
Multiply both sides by 3: 3 = x - 3. Then x = 6, and the x-int. is (6, 0).
Find the y-int by setting x = 0 and solving for y:
</span><span>y+1=1/3(0−3)
Mult both sides by 3: 3y+3 = -3, so that 3y = -6, and y = -2.
Then the y-intercept is (0,-2).
Plot these 2 points. Then draw a line thru them.</span>
