Answer:
there
Step-by-step explanation:
T = 4 + 2A
S = 5A - 8
T = S
Since T and S are equal, set them against each other
2A + 4 = 5A - 8
Subtract 2A from each side, and add 8 to each side
12 = 3A
Divide each side by 3
A = 4
If Andrew is 4, then Tom is twice that plus 4, or 12. Sarah is 5 times 4 less 8, or 12.
Step-by-step explanation:
The formula for calculating the area of a square is expressed as;
A = x² where;
x is the length of one side of the square
Given
x = 10in
A = 10²
A = 10 * 10
A = 100in²
Area of the square with side length 10in is 100in²
From the equation A = x², we can see that as the value of x increases, the value of the area also increases and vice versa. This means that the area of the square is directky proportional to its length. Hence we can say YES, the area of a square and the length of its side directly proportional
Answer:
45
Step-by-step explanation:
45 is constant, because no mater how many miles you drive, you will always be charged $45. It stays the same
Answer:
It would be a rational number.
Step-by-step explanation:
An easy way to tell if a number is rational is by seeing if it can be put in fraction form. As you can see, 27/100 is a fraction, so it is rational.
Slope Intercept Form Equation: mx + b = y
Use the slope, like 3/2 or 4, but first plot the y-intercept, like 3, and then put the equation to these: y = 3/2x + 4 or y = 4x + 4. Plot the y-intercept on the y- axis (the vertical line). If you were to use my examples, you would plot the y-intercept by (0,4). Then if you used my first example equation, move 2 to the right of the plotted coordinates and then up by 3. If you were to use my second equation, however, then you would move to the left of the same plotted coordinates, (0,4), 1 to the right and then up 4.
