Help!!! I'm Not Really Good At Graphs So I Also Need An Explanation Please!

Answers

Answer 1

Answer:

Hi, I think it's DEGF

Step-by-step explanation:

for y=x－2,

just move y=x down 2 units.

for x=－2,

it's the easiest one, just see if there is a vertical crossing －2 on the x-axis.

for－2x+4,

you can see it as move y=－2x up 4 units, and for y=－2x, you can find it out by sub (1,-2) and (0,0) onto the graph.

for x²-4,

see it as y=x² moved down 4 units. for y=x², it's simply a parabola which is symmetrical along y-axis and crossing (0,0). And remember that since the coefficient of x² is positive, the graph is open upward.

Hope this will help u!!

#1: what percent of 78 is 16?

#2: what is 79% of 55?

Answers

Answer:

1.   487.5%

2.  43.45

Step-by-step explanation:

Remember the formula for a proportion: ((part)/(whole)) = ((percent)/(100))

1.

The part is given, 78, and the whole is given, 16.

Set up a porportion:

78/16 = percent/ 100

Simplify:

39/8 = percent /100

Cross products

39/8 = percent/100

8percent = 3900

Inverse operations

8percent = 3900

/8     /8

percent = 487.5

487.5%

2.

The percent is given, and the whole is given.

Set up a proportion:

The cost in dollars, y, of a large pizza with x toppings from Pat's Pizzeria can be modeled by a linear function. A large pizza with no toppings costs $14.00. A large pizza with toppings costs $17.50.

Answers

Given :

A large pizza with no toppings costs $14.00. A large pizza with toppings costs $17.50 .

To Find :

The cost in dollars y, of a large pizza with x toppings from Pat's Pizzeria.

Solution :

Let, equation is :

y = mx + c    ....1)

Case 1 : With no toppings.

y = 14 = m(0) + c

c = 14

Case 2 : With 1 toppings i.e x = 1 .

y = 17.50 = m( 1 ) + c

17.50 = m + 14

m = 3.5

Putting value of c and m in equation 1, we get :

y = 3.5x + 14

Hence, this is the required solution.

Answer:

FIGURE 1:

x = 118; y = 96

FIGURE 2:

x = 85; y = 65

Step-by-step explanation:

FIGURE 1:

You know that x = 118 because of the Corresponding Angles theorem.

Because of the Exterior Angle Theorem (triangles), you can then figure out what y is with the following equation: y + 22 = 118 to get y = 96.

FIGURE 2:

In this figure, you first need to determine what the third angle in the bottom right triangle is. Using the Triangle Sum Theorem, you would find that the third angle is 70.

Because of the Vertical Angles Theorem, you know that the third angle in the top left triangle is also 70. With this information, you can now solve for x using the Triangle Sum Theorem to get x = 85.

Now that you know x, you can solve for y. The other 3 angles in the quadrilateral in which y is a part of are 90, 110, and 95. These could be figured out using the Linear Pair Postulate, the Vertical Angles Theorem, and the Linear Pair Postulate respectively. Now you can figure out y by using the Quadrilateral Sum Conjecture to get y = 65.

A 17-ft ladder leans against a building so that the angle between the ground and the ladder is 71°. How high does the ladder reach on the building? (Round your answer to the nearest foot.)

Answers

Answer:

there is 16.08 foot high does the ladder reach on the building

Step-by-step explanation:

The computation of the high does the ladder reach on the building is shown below:

Given that

length of the ladder = 17 ft

angle -between the ground and the ladder = 75 degrees

Based on the above information

Here we used the trig-ratio to calculate the same

[tex]Sin \theta = \frac{oppo}{hyp} \\\\Sin 71^{\circ} = \frac{h}{17}[/tex]

0.946 × 17 = h

The height is 16.08 foot

Hence, there is 16.08 foot high does the ladder reach on the building

Hopefully someone fills in the rest of the answers!!!

Answer:

Question 1:

8/12 = 4/6 = 3/x

0.6 = 0.6 = 3/x

It is a similar triangle, therefore 3/x = 0.6

x = 5 because 3/5 = 0.6

Question 3:

B

D

Question 4

You got question 4 wrong since similar triangles have similar ratio.

8/10 = 8/10 = 10/14

0.8 = 0.8 = 0.7

Correct answer for question 4 is B("No they are not similar because the ratios are not equal")

Question 5

The Quadrilaterals are similar. Therefore:

22.4/14 = 12.8/8 = 12/7.5 = 26/x

1.6 = 1.6 = 1.6 = 26/x

Meaning 26/x = 1.6

x = 16.25

Because 26/16.25 = 1.6

where x is a person’s IQ. Solve the inequality to find the IQ scores for the middle 50% of the population.

Answers

Answer:

9992≤x 10038

Step-by-step explanation:

Given the expression

∣x−10015∣∣≤23, we are to find the range of values of x

since the function is in a modulus sign, it can be expressed as a negative and positive function.

If the function is positive;

x -  10015 ≤23

x ≤23 + 10015

x ≤ 10038

If the function is negative;

-(x-10015)≤23

-x+10015≤23

-x≤23-10015

-x≤-9992

multiply through by -1

x ≥ 9992 (note the inequality sign change)

9992≤x

Combine both inequalities

9992≤x and x ≤ 10038

On combining;

9992≤x 10038

Hence the inequality to find the IQ scores for the middle 50% of the population is expressed as 9992≤x 10038

We want to solve an inequality to find the range of IQ scores for half of the population.

We will find that the range is:

77.15 ≤ x ≤ 123.15

The inequality we need to solve is:

|x - 100.15| ≤ 23

To solve it, we write two inequalities.

x - 100.15 ≤ 23

x - 100.15 ≥ -23

Solving these two, we will get the maximum and minimum of the range.

The maximum is given by:

x - 100.15 ≤ 23

x  ≤ 23 + 100.15 = 123.15

The minimum is given by:

x - 100.15 ≥ -23

x  ≥ -23 + 100.15 = 77.15

Then the range is:

77.15 ≤ x ≤ 123.15
