what inequality does this graph represent?

Answers

Step-by-step explanation:

Answer:

y ≤ 3x - 2

Step-by-step explanation:

Let's get the line using 2 points of the graph:

(0, -2) and (1, 1)

Slope-intercept formula:

y = mx + bm = (1 - (-2))/(1 - 0) = 3/1 = 3b = - 2 as per (0, -2) point

So the line is:

y = 3x - 2

The line is solid and shaded area is lower part, therefore the inequality is:

y ≤ 3x - 2

What is the domain of the function f(x) = x+ 2?

Answers

Answer: Choice D) [tex]x \ge -6[/tex]

=========================================================

Explanation:

Taking the square root of a negative number leads to a nonreal result.

So we want the radicand to be 0 or positive

Set the stuff under the square root to be 0 or larger. Solve for x.

[tex]\frac{1}{3}x+2 \ge 0\\\\\frac{1}{3}x \ge 0-2\\\\\frac{1}{3}x \ge -2\\\\x \ge 3(-2)\\\\x \ge -6[/tex]

If x is -6 or larger, then [tex]\frac{1}{3}x+2[/tex] is 0 or larger leading to some real number for f(x).

The inequality sign does not flip because we multiplied both sides by a positive number. The inequality sign only flips when we multiply both sides by a negative number.

Wilma estimates that she'll drive about 18,000 miles during the year. The car she wants to purchase gets an
average of 24
miles per gallon, and the average cost per gallon of gas in her neighborhood is $2.72. Locate the error in her calculations,
and select the correction.
Step 1
18,000 miles/year
18.000 miles = 1,500 miles/month
12 months
Step 2
1.500 miles/month
125 gallons/month
12 miles/gallon
Step 3
(125 gallons/month) x ($2.72/gallons) = $340 cost/month

Answers

Given parameters:

Distance in a year = 18000miles

Car mileage = 24miles/gallon

Average cost per gallon = $2.72 per gallon

Problem;

Find the error in her calculation;

Step 1

18,000 miles/year

18, 000 miles = 1,500 miles/month -- Since there are 12months in a year

12 months

Step 2

1500 miles/month

Car mileage = 24miles/gallon

Gallons per month; [tex]\frac{1500}{24}[/tex] = 62.5gallons/month

125 gallons/month this is an error and should be 62.5gallons/month

12 miles/gallon should be 24miles per gallon

Step 3

(125 gallons/month) x ($2.72/gallons) = $340 cost/month

Correct

Step 2 is wrong because it uses wrong values.

Answer:

Option 1

Alternate Exterior Angles Theorem

Two angles that are on different sides of the transversal and outside of the two parallel lines are congruent (=).

Same-side Interior Angles Theorem

Two angles that are on the same side of the transversal and inside of the two parallel lines are supplementary (= 180).

Same-side Exterior Angles Theorem

Two angles that are on the same side of the transversal and outside of the two parallel lines are supplementary (=180).

Corresponding Angles Theorem

Two angles on a figure that correspond are congruent (=).

Now, let's look at the figure and apply these theorems.

[tex]z[/tex] and [tex]86[/tex] are same-side exterior angles, meaning they're supplementary:

[tex]z+86=180[/tex]

Subtract [tex]86[/tex] from both sides of the equation:

[tex]z=94[/tex]

Now that we know our [tex]z[/tex] value, let's recognize that [tex]z[/tex] ([tex]94[/tex])corresponds to [tex]x+32[/tex], meaning they're congruent:

[tex]x+32=94[/tex]

Subtract [tex]32[/tex] from both sides of the equation:

[tex]x=62[/tex]

Let's find the value of the angle:

[tex](62)+32[/tex]

Add:

[tex]94[/tex]

Since the corresponding angles are of the same value, they're congruent, proving our [tex]x[/tex] & [tex]z[/tex] values correct.

Since [tex]y[/tex] and the angle represented by the expression [tex]x+32[/tex] ([tex]94[/tex]°) are alternate-interior angles, they are congruent:

[tex]y=94[/tex]

During her first year of college, Sara put $2000 in the bank to save for a trip to Italy after graduation. The money earned 3% simple annual interest. After 4 years, how much money did she have in the bank for her trip?

Answers

a lotStep-by-step explanation:

Answer:

2,240

Step-by-step explanation:

Sara will have US$ 2,251.02 in the bank after 4 years for her trip to Italy.

Step-by-step explanation:

1. Let's review the data given to us for solving the question:

Investment of Sara during her 1st year of college = US$ 2,000

Duration of the investment = 4 years

Annual interest rate = 3%

2. Let's find the future value of this investment after 4 years, using the following formula:

FV = PV * (1 + r) ⁿ

PV = Investment of Sara during her 1st year of college = US$ 2,000

number of periods (n) = 4

rate (r) = 3% = 0.03

Replacing with the real values, we have:

FV = 2,000 * (1 + 0.03) ⁴

FV = 2,000 * (1.03) ⁴

FV = 2,000 * 1.12550881

FV = 2,251.02

Sara will have US$ 2,251.02 in the bank after 4 years for her trip to Italy. Later you round the answer and that gives you 2,240
