What is the y-intercept? y-3=1\2(x+2)

1 answer:

6 0

Y-3=1/2(x+2)

To find the y-intercept, we must first get the equation in slope intercept form. Start off by distributing 1/2 into the parentheses.

y-3= 1/2x+1
Add 3 to both sides

y= 1/2x+4

The slope is whatever is in front of x, in this case, 1/2. The y-intercept is the number after that which would be 4

Answer:

{0, 1, 16, 81}

Step-by-step explanation:

If the domain of this function is the set {0, 1, 4, 9}, we find the set representing the range by evaluating the function at each of the four values in the domain.

f(0) = 0

f(1) = 1

f(4) = 16

f(9) = 81

and so the range is the set {0, 1, 16, 81}.

the length and width of a rectangle are whole numbers of centimeters. neither is divide by 6.the area of the rectangle is 36 squ

liraira [26]

Note that

36=1·36;
36=2·18;
36=3·12;
36=4·9;
36=6·6.

If neither (length and width) is divide by 6, then cases 1, 2, 3 and 5 are extra, because

36:6=6 (is divide by 6);
18:6=3 (is divide by 6);
12:6=2 (is divide by 6);
6:6=1 (is divide by 6).

The only possible dimensions are: width - 4 cm and length - 9 cm.

Then the perimeter is

$P=4+9+4+9=26$ cm.

Answer: 26 cm.
