Answer:

60°

Step-by-step explanation:

The sum of the angles in any quadrilateral is 360°. In a parallelogram the sum of neighboring angles is 180°. Therefore:

2x + x = 180°

3x = 180°

x = 60°

What is 16.281 rouned to the nearest tenth
tatyana61 [14]

Answer:

16.3

Step-by-step explanation:

The tenth place is right after the decimal, afterwards, its hundredths and then thousandths. The number after the tenth's place is 8. Since the number is 5 and above, you round up and add 1 to the tenths place to get 16.3. If the hundredths was 4 and below it would round to 2.

Graph the quadratic functions y = -2x^2 and y = -2x^2 + 4 on a seperate piece of paper. Using those graphs, compare and contrast
Andrei [34K]

Answer:

Shape is parabolic and there is translation of 4 unit upward.

Step-by-step explanation:

Given : The quadratic functions y = -2x^2 and y = -2x^2 + 4

To find : Using those graphs, compare and contrast the shape and position of the graphs?

Solution :

Let, y_1= -2x^2

and  y_2= -2x^2 + 4

Now, we plot these two equations.

The graph of y_1= -2x^2  is shown with green line with vertex(0,0)

The graph of y_2= -2x^2 + 4  is shown with violet line with vertex(0,4)

We have seen in the graph that the graph of y_2 is shifted 4 unit upward with the graph of y_1

Transformation to upward,

f(x)→f(x)+b , the graph of f(x) is shifted upward by b unit.

The shape of both the graph is parabolic but the position is different.

There is a 4 unit upward translation.

Refer the attached graph below.

a cellphone priced at $98 is in sale for 25% off, it includes a 10% tax, will i have enough money to buy the phone with $80? wha
Ipatiy [6.2K]

Answer:

No, the phone will be $6.24 over from $80

the tax is 7.84

Step-by-step explanation:

For sale:

98 ÷ 1.25 = 78.4

Tax:

78.4 x 1.1 = 86.24 <- Total price with sale and tax.

(86.24 > 80) ❌

86.24 - 78.4 = 7.84 <- Tax amount

AlexFokin [52]

Answer:

5

General Formulas and Concepts:

<u>Algebra I</u>

Parallel lines have the same slope

Slope-Intercept Form: y = mx + b

  • m - slope
  • b - y-intercept

Step-by-step explanation:

Parallel lines have the same slope but different y-intercepts.

Our given slope is 5. Therefore, our parallel slope is also 5.
