Answer:

Option 1

Step-by-step explanation:

Functions cannot have two points with the same x-value or in this case, value on the left side. This means it must be the first option. This is because of how in the second option, each shape on the right matches with a different shape on the left. In option three, each number on the left matches to a different number on the right. This is the same with option four.

<h3>For the lowest common multiple you do your times tables.</h3><h3>For example,5,10,15,20,25,30,35,40,45,50.</h3><h3>Those are your times tables of 5.</h3><h3>On the other side do your 6 times tables up to 60.</h3><h3>6,12,18,24,30,36,42,48,54,60.</h3><h3>Now that you have got both,Write down the smallest number in them that they both have.</h3><h3>For example,it would be<u> 30.</u></h3>

This is because that’s the smallest number in the multiple of both numbers.

Answer:

$(x+\frac{7}{2} )^{2} -\frac{69}{4}$

Step-by-step explanation:

$x^{2} +7x-5=(x+\frac{7}{2} )^{2} -(\frac{7}{2})^{2} -5\\\\=(x+\frac{7}{2} )^{2} -((\frac{49}{4})+\frac{20}{4}) \\\\=(x+\frac{7}{2} )^{2} -\frac{69}{4}$

Answer:

5 miles

Step-by-step explanation:

An hour and 25 minutes is 85 minutes. Using the given information we can find the distance d with the proportion ...

$\dfrac{\text{distance}}{\text{time}}=\dfrac{d}{85\text{ min}}=\dfrac{1\text{ mi}}{17\text{ min}}\\\\d=\dfrac{85\text{ min}}{17\text{ min}}(1\text{ mi)}\qquad\text{multiply by $85$ min}\\\\d=5(1\text{ mi})\qquad\text{simplify}\\\\d=\boxed{5\text{ mi}}$

In 1 hour and 25 minutes, Nick will travel 5 miles.
