Mathematics
1 answer:
Otrada [13]3 years ago
6 0

Answer:

y=√x+5 -1

the answer is option C,,

x=-7,y=√-7+5 -1=√-2 -1

we can't find the square root of negative values, therefore it displays as error

x=-6,y=√-6+5-1=√-1 -1

same reason

x=-5,y=√-5+5-1=√0-1=-1

x=-4,y=√-4+5-1=√1-1=0

x=-1,y=√-1+5-1=√4-1=1

x=4,y=√4+5-1=√9-1=2

Determine the range of the graph above
kozerog [31]

Answer:

The range of the graph is:

-3 ≤ y ≤ 3

Hence, option (B) is correct.

Step-by-step explanation:

We know that the range of a function is the set of values of the dependent variable 'y' for which a function is defined.

From the given graph, it is clear that the graph goes down at y=-3 and then goes up to y=3  and then goes down again.

In fact, this indicates that the range of the graph lies between y=-3 to y=3

Therefore, the range of the graph is:

-3 ≤ y ≤ 3

Hence, option (B) is correct.

What is the best estimate of 687 × 391?<br><br> 280,000<br> 210,000<br> 240,000<br> 180,000
ra1l [238]

Answer:

Step-by-step explanation:

Estimating a sum by rounding to get the best estimate is the goal of this lesson. Notice that we try to estimate. We don't need to have an exact answer!

Notice that for numbers with two digits, there can only be one estimate because you can only round to the tens place.

Estimate the following sums: 36 + 21, 74 + 15, and 85 + 24

36 + 21 = 40 + 20 = 60

74 + 15 = 70 + 20 = 90

Write as a unit rate: 36 gallons to 9 minutes *
Nataly_w [17]

Answer

36/9= 4

Step-by-step explanation:

This is a fraction equal to

36 gallons ÷ 9 minutes

We want a unit rate where

1 is in the denominator,

so we divide top and bottom by 9

36 gallons ÷ 9

9 minutes ÷ 9

=

4 gallons

1 minute

=

4 gallons

minute

= 4 gallons per minute
