Answer:
-7
Step-by-step explanation:
y = mx + b is slope-intercept form and m is the slope. In this case m = -7 so the slope is -7.
Answer:
59049
1 / 59049
Step-by-step explanation:
for five digit pin
five blank spaces are there to fill
as repetition is allowed every blank space has 9 possible digits to fill
so total ways = 9 * 9 * 9 * 9 * 9 = 9^5 = 59049
so probability is 1 / 59049 as there is only one correct code
refer the picture below
Answer: X = (
, 6)
Step-by-step explanation:
x(4x - 19) = 30
4x^2 - 19x = 30
4x^2 - 19x - 30 = 0
ax^2 + bx + c = 0
= 
= 6
=
= 
= -1.25
X = (, 6)
8,425 ÷ 10.25 = 821.95
You would round up so to earn $8,425 you would need to work 822 hours

[Right Triangles Only] Pythagorean Theorem: a² + b² = c²
- a is a leg
- b is another leg
- c is the hypotenuse<u>
</u>
Step-by-step explanation:
<u>Step 1: Identify</u>
<em>a</em> = 12
<em>b</em> = 5
<em>c</em> = x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Substitute in variables [PT]: 12² + 5² = x²
- Evaluate exponents: 144 + 25 = x²
- Add: 169 = x²
- [Equality] Square root both sides: ±13 = x
- Rewrite: x = ±13
Since we are dealing with positive numbers, we can disregard the negative root.
∴ x = 13
