Which inequality can be used to determine the amount of money the family still needs to save?
Tju [1.3M]

Answer:

The inequality equation is

(2,764 + x) ≥ 5,000

Solving further, we obtain

x ≥ 2,236

where x is the amount of money the Li's family still need to save.

Step-by-step explanation:

Li’s family is saving money for their summer vacation. Their vacation savings account currently has a balance of $2,764. The family would like to have at least $5,000.

Which inequality can be used to determine the amount of money the family still needs to save?

Solution

Let x represent the amount of money the Li's family still need to save.

It is given that the family already have $2,764 in their savings account and the family needs at least $5,000.

The total amount the family will have in total, after saving x dollars to join the already saved $2,764 will now be

$(2,764 + x)

This amount must be at least $5,000, that is, this amount must be greater than or equal to $5,000.

So, the inequality equation is then

(2,764 + x) ≥ 5,000

Solving further by subtracting 2,764 from both sides, we obtain

x ≥ 2,236

Hope this Helps!!!

Here is a sketch of a curve.
Ugo [173]

Answer:

The turning point of the graph is at (3,-16)

Step-by-step explanation:

The general equation of curve is given as:

y = x² + ax + b

The two point for which the equation satisfies is (0,-7) and (7,0).

Substitute (0,-7) in the general equation:

y = x² + ax + b

-7 = 0² + a(0) + b

b = -7

Substitute (7,0) in the general equation:

y = x² + ax + b

0 = 7² + 7a + b

Where b = -7

0 = 49 + 7a - 7

0 = 42 + 7a

a = -6

The equation of the curve is:

a = -6 and b = -7

y = x² + ax + b

y = x² - 6x - 7

Graph of the equation is attached below.

We can see that the the turning point of the graph is at (3,-16)
