Answer: D, Put it in stocks
Step-by-step explanation: It’s not B, C, and A because Donald said that he doesn’t trust banks or markets. And the A wouldn’t be the answer either cause safes are from banks
Answer:
PQR+SQR=180°(angles in a triangle)
75°+SQR=180°
SQR=180°-75°
SQR=105°
<em>w(t)</em> tells you the amount of water <em>w</em> at a given time <em>t</em>.
The inverse function tells you at which time <em>t</em> the tank contains an amount of water <em>w</em>.
To get the inverse function, solve the equation
<em>w</em> = 80 - 2.8<em>t</em>
for <em>t</em> :
<em>w</em> = 80 - 2.8<em>t</em>
2.8<em>t</em> = 80 - <em>w</em>
<em>t</em> = (80 - <em>w</em>) / 2.8
<em>t</em> ≈ 28.57 - 0.357 <em>w</em>
The graph of <em>w(t)</em> is a downward-sloping line. The graph of the inverse is also a downward-sloping line, but its intercept (28.57) and slope (-0.357) are both smaller than the intercept and slope of <em>w(t)</em>.
Step-by-step explanation:
step 1. (1) 5a +8c +4p = 57
(2) 9a +8c + 7p = 89
(3) 8a + 4c + 5p = 68.
step 2. this is a 3 variable system. solve the system.
step 3. eliminate c from (1) and (2) and also from (2) and (3). so you now have 4a + 3p = 32 and 7a + 3p = 47. now you have a two variable system
step 4. eliminate p by subtracting: 3a = 15 so a = 5.
step 5. if a = 5 then p = 4 ( plug into step 3)
step 6. if a = 5, p = 4, then c = 2 (plug into step 1).
step 7. apples = 5, pears = 4, cherries = 2.
