Find the value of x + 3.
X + 3
18 cm
2x - 4

The absolute value inequality graphed is:

y ≥ |x - 5| + 1

We can see that we have an absolute value equation, and the region above the graph is shaded, so we have:

y ≥ absolute value equation

We can see that the slope of the absolute value equation is 1, and the vertex is (5, 1), then the equation is:

|x - 5| + 1

Replacing that in the inequality we will get:

y ≥ |x - 5| + 1

That is the graphed inequality.

Answer:

y = -2/7x + 2

Step-by-step explanation:

y=mx + b is the slope intercept form of a line.  The b is the y-intercept.  We are given that.  The point (0,2) tells us that the line crosses the y intercept at 2.

Now we have to find the slope.  The slope is the change in y over the change in y.  Given the points (7,0) and (0,2)  The y's are 2 and 0 and the x's are 0 and 7.  Subtract the y's and subtract the x's.

[tex]\frac{2 - 0}{0 - 7}[/tex] = [tex]\frac{-2}{7}[/tex]

Now we can put in the slope and the y-ntercept

y = mx + b

y = [tex]\frac{-2}{7}[/tex]x + 2

The unknown angle of the right triangle is as follows:

∠CBA = 28.8°

The triangle is a right triangle because one of its angle is equals to 90 degrees.

The angle  ∠CBA, can be found using trigonometric rations,

hence,

tan ∅ = opposite / adjacent

where

∅ = ∠CBA

Therefore,

tan ∠CBA = opposite / adjacent

opposite side = 5.6 m

adjacent side = 10.2 m

Hence,

tan ∠CBA = 5.6 / 10.2

tan ∠CBA = 0.54901960784

tan ∠CBA = 0.54901960784

∠CBA = tan⁻¹ 0.54901960784

∠CBA = 28.7676493388

∠CBA = 28.8°

If angle m∠SOP=(7y-12)° and m∠SOR=(5y+12)°, then the value of y=15 and m∠SOP is equal to 93°.

Given that m∠SOP=(7y-12)° and m∠SOR=(5y+12)°.

We are required to find the value of y and the angle m∠SOP.

We know that sum of all the angles which lie on the straight line is equal to 180°.

And here m∠SOP and m∠SOR both lie on the straight line PR. So,

m∠SOP+m∠SOR=180

7y-12+5y+12=180

12y=180

y=180/12

y=15

We have to use y=15 in m∠SOP=(7y-12)°.

m∠SOP=7*15-12

=105-12

=93°

Hence if angle m∠SOP=(7y-12)° and m∠SOR=(5y+12)°, then the value of y=15 and m∠SOP is equal to 93°.

Answer:

62º

Step-by-step explanation:

So this is supplementary angles. Supplementary angles are two or more angles that add up to 180º. This is also vertical angles. Vertical angles are angles across from one another that are congruent(such as the 180º angle and the one up and to the right of it). So if vertical angles are congruent that means that the angle to the right of x is also 118º. And since it is a supplementary angle this is now simple subtraction.

180-118=62.

by comparing the two maps, we get that, the map with the scale of 1 inch to 2,000 feet is smaller than the map of scale of 1 inch to 1,500 feet as it includes more area in a single inch.

We are given that:

A map of the city has a scale of 1 inch to 2,000 feet.

This means that 1 inch of the map represents the 2,000 feet of the actual area of the city.

Now, we are given another map which has a scale of 1 inch to 1,500 feet.

This means that 1 inch of the map represents the 1,500 feet of the actual area of the city.

So, by comparing the two maps, we get that, the map with the scale of 1 inch to 2,000 feet is smaller as it includes more area in a single inch.

Therefore. by comparing the two maps, we get that, the map with the scale of 1 inch to 2,000 feet is smaller than the map of scale of 1 inch to 1,500 feet as it includes more area in a single inch.

Explanation:

The parent function y = |x| has its vertex at the origin (0,0). This is the lowest point on the V shaped graph.

The -2 at the end will shift every point 2 units down. This is because we're subtracting 2 from the y coordinate of each point.

So the vertex (0,0) moves down to (0, -2)

The graph is below.

Using proportions, it is found that the height of the object is of 12 m, hence you can use a ladder that reaches height of up to 13 m to climb the object.

A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.

Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.

For similar triangles, equivalent side lengths are proportional, hence, in this problem, we have that:

h/1.5 = 8.8/1.1

h/1.5 = 8

h = 8 x 1.5

h = 12m.

For given question,

Alita received twenty-two dollars, seven quarters, and five dimes as change at the grocery store.

The value of coins is all counted in cents.

1 Penny = 1 cent  

1 Nickel = 5 cents  

1 Dime = 10 cents  

1 Quarter = 25 cents

And 1 Dollar = 100 cents

Alita received seven quarters, and five dimes coins as change at the grocery store.

seven quarters = (7 × 25) cents

                         = 175 cents

five dimes =  (5 × 10) cents

                 = 50 cents

The total coins are:

seven quarters, and five dimes

= 175 + 50 cents

= 225 cents

Now we add all change together.

twenty-two dollars, seven quarters, and five dimes

= 22 dollars + 225 cents

Answer:

p = 6

Step-by-step explanation:

Define the variable

Let p be the number of people who go to the amusement park.

Given information:

Therefore, the equation that represents the given information and the defined variable is:

[tex]39.25p + 12 \leq 247.50[/tex]

(We have used the inequality sign since the question states the maximum amount of money the group of friends have to spend).

To solve, subtract 12 from both sides:

[tex]\implies 39.25p + 12 - 12 \leq 247.50 - 12[/tex]

[tex]\implies 39.25p \leq 235.50[/tex]

Divide both sides by 39.25:

[tex]\implies \dfrac{39.25p}{39.25} \leq \dfrac{235.50}{39.25}[/tex]
