B. Upside Down V- Shaped
When you draw it out, it looks like a upside down V.
Answer:
9
Step-by-step explanation:
Compare your x2 + y2=81 to the following:
x^2 + y^2 = 81
The " ^ " symbol indicates exponentiation.
Now compare x^2 + y^2 = 81 to
x^2 + y^2 = r^2.
This is the standard equation of a circle of radius r centered at the origin, (0,0). You can see for yourself that 81 must equal r^2.
Taking the square root of 81, we get plus or minus 9.
But the radius must be positive, so we reject the -9 and take +9.
The radius is 9.
Answer:
0.8
Step-by-step explanation:
Things to remember:
- You can add as many 0's on the end of a decimal and it will still equal the same number, as long as the 0's are on the right side of the decimal point. For example, 0.7 = 0.7000.
- The lowest value has the lowest probability
So, let's rewrite the options with the same amount of decimal points:
1.00
0.90
0.80
0.85
Now, find the value under 0.82. In this option, the lowest value is 0.80, and it is under 0.82, so it is the answer.
<span>5y = 10x - 15
y = -5x - 3
so slope = -5
x - intercept when y = 0
</span> -5x - 3 = 0
-5x = 3
x = -3/5
(-3/5, 0)
y - intercept when x = 0 then y = -3 (0,-3)
answer
slope = -5
x-intercept (-3/5, 0)
y-intercept (0, -3)
