Option A would be your answer. We know 71 is the product. We also know that Sues age is one year less than half her mothers age. -1 comes from the problem saying one year less. We can already eliminate the other 3 options at this point.
The angle is the arctangent of the ratio of ay to ax. Since ay is negative and ax is positive, it is a 4th-quadrant angle.
... arctan(ay/ax) = arctan(-4.00/3.90) ≈ 314.27°
... about 5.48513 radians
Answer: y = 1/5x + 6
Step-by-step explanation:
Answer:
m = 6
Step-by-step explanation:
Step 1: Write out equation
-11 = -3m + 7
Step 2: Subtract 7 on both sides
-18 = -3m
Step 3: Divide both sides by -3
6 = m
Step 4: Rewrite
m = 6
<span>f(x)=|2x+1|+5
f(-3) = </span><span>|2*-3 + 1|+5
= </span><span>|-6 + 1|+5
</span>= <span>|-5|+5 = 5 + 5 = 10
</span><span>
f(-3) = 10 </span><span>
</span>
