The answer is E. This inequality best suits the given because in order to achieve an A she must have an average of the three test scores in which the last test score must be higher than or equal to 94. Hope this helps and have a good day!
Answer:
15.5 inches
Step-by-step explanation:
height² = diagonal² - length²
height = √(32² - 28²) ≅ 15.5 inches
Answer:
C
Step-by-step explanation:
It's difficult to see the answer options. However, this graph is not a direct variation of the form y=kx. In order to be direct variation, the function must be proportional and run through the origin. If you continue the points to the left, it will not cross at the origin (0,0). But this is a function, so C is the best choice.
Answer:
one solution
Step-by-step explanation:

Step-by-step explanation:
<u>Step 1: Define</u>
-84 = -2(2 + 5k)
<u>Step 2: Solve for </u><em><u>k</u></em>
- Divide -2 on both sides: 42 = 2 + 5k
- Isolate <em>k</em> term: 40 = 5k
- Isolate <em>k</em>: 8 = k
- Rewrite: k = 8
<u>Step 3: Check</u>
<em>Plug in k into the original equation to verify it's a solution.</em>
- Substitute in <em>k</em>: -84 = -2(2 + 5(8))
- Multiply: -84 = -2(2 + 40)
- Add: -84 = -2(42)
- Multiply: -84 = -84
Here we see that -84 does indeed equal -84.
∴ k = 8 is the solution to the equation.
