Find the x-intercepts, use the zero product property, r(r+7)=0

Answer:

  r = 0

  r = -7

Step-by-step explanation:

There is no x in the equation, hence there are no x-intercepts.

__

If we assume you want the values of r that satisfy the equation, the zero product property tells you they will be the values that make the factors zero.

The factors are r and (r+7).

The factor r is zero when ...

  r = 0

The factor (r+7) is zero when ...

  r +7 = 0   ⇒   r = -7

The "x-intercepts" are r=0 and r=-7.

Need help with this problem
alexandr1967 [171]

Answer:

x = 10

Step-by-step explanation:

Since the triangles are similar the ratios of corresponding sides are equal

\frac{20}{20+8} = \frac{3x}{4x+2}, that is

\frac{20}{28} = \frac{3x}{4x+2} ( cross- multiply )

20(4x + 2) = 84x

80x + 40 = 84x ( subtract 80x from both sides )

40 = 4x ( divide both sides by 4 )

x = 10

What is the interquartile range of this set of data? 15, 19, 20, 25, 31, 38, 41
Irina18 [472]
First, you have to find the median, which is the number in the middle: 25

Then cut the data in half by the median, so your new data sets are
15,29,20
    and 
31,38,41

Now you find the median of both of those sets, which is 29 and 38.

The interquartile range is the difference between the numbers, so 38-29 = 9.

Dans un magasin de sport, une paire de chaussures coûte 69,30 €, après une remise de 30 %. Quel était le prix initial (avant la
galben [10]

Answer:

€99

Step-by-step explanation:

The computation of the original price (before the rebate)  of this pair of shoes is shown below:

Given that

The cost of pair of shoes is € 69.30 i.e. after 30% discount

So, the original price would be

= € 69.30 × 100 ÷ 0.70

= €99

The € 69.30 shows the 70% value according to this we determine 100% value
