1/2t + 3/8
t = 1/4
<u>Step 2: Evaluate</u>
- Substitute: 1/2(1/4) + 3/8
- Multiply: 1/8 + 3/8
- Add: 4/8
- Simplify: 1/2
Answer:
false
a rhombus <u>only</u> has 4 equilateral sides and a square has 4 equilateral sides <u>and</u> all interior angles are right angles therefore that question is false

Answer:
- center: (0, 3)
- radius: 2√2
Step-by-step explanation:
The equation can be put into standard form by "completing the square" for each variable. The x-term is already a square, so we need do this only for the y-term.
x^2 +(y^2 -6y) = -1
x^2 +(y^2 -6y +9) = -1 +9 . . . . . . add (-6/2)^2 to complete the square
x^2 +(y -3)^2 = 8 . . . . standard form equation
__
Comparing the above equation to the form:
(x -h)^2 +(y -k)^2 = r^2 . . . . . . . circle centered at (h, k), radius r
we see that (h, k) = (0, 3) and r^2 = 8 ⇒ r = 2√2.
The center point is (0, 3); the radius is 2√2.
Answer:
Step-by-step explanation:
To graph an equation using the slope and y-intercept, 1) Write the equation in the form y = mx + b to find the slope m and the y-intercept (0, b). 2) Next, plot the y-intercept. 3) From the y-intercept, move up or down and left or right, depending on whether the slope is positive or negative.
