where the first equation is true if -5
x
2 and the second equation is true if x
2. Graph the line like you would for an equation thats in y=mx+b format. See the graph I provided for an idea of what you should make.
For the red line,
the segment in between the points is what you want to graph. The points should be
solid. This is because it is a "less than or equal to" equation. For the blue line,
the segment below the point is what you need to graph. The point should be
solid for the same reason as above.
Answer:
There is a significant decrease in the average price homes.
Step-by-step explanation:
Let X represent the prices of homes sold in the U.S. in the past year
given that
Create hypotheses as
(Left tailed test at 5% significance)
Mean difference = -10000
Std error of mean =
Since population std deviation is known, we can do z test
Z = mean diff/std error = -2.50
p value = 0.00621
Since p <0.05 we reject null hypothesis.
There is a significant decrease in the average price homes.
Step-by-step explanation:
f(x) = y ( true statement)
y = -1/5x + 3
To find the inverse of any given function we switch the X and Y
X = -1/5y + 3
isolate y so:
x-3 = -1/5y
Multiply both sides by -5
-5(x-3) = y
-5x + 15 = y
No. The value in the hundreds place represents 500, whereas the value in the tens place represents 50. The value in the hundreds place is 10 times as great as the value in the tens place.
Answer:
11 yards
Step-by-step explanation:
<em>Given :</em>
<em>Maria got a prepaid debit card with $20 on it. </em>
<em>For her first purchase with the card,</em>
<em> she bought some bulk ribbon at a craft store.</em>
<em> The price of the ribbon was 8 cents per yard.</em>
<em>To Find:</em>
<em> If after that purchase there was $19.12 left on the card, how many yards of ribbon did Maria buy?</em>
<em>Solution:</em>
<em>$20- 19.12= 0.88</em>
<em>She spent 0.88 on the ribbon</em>
<em>One yard of ribbon is $0.08</em>
<em>0.88/0.08 = 11</em>
<em>Therefore she bought 11 yards of ribbon</em>
