Explain how you can tell whether the sum of two numbers is positive or negative before you add. Give examples to illustrate your point.

Answers

Answer 1
2 negatives always make a negative -4 and -3 = -7
If a postive number is bigger than the negative number it will be positive 50 - 49= 1
Bigger Negative number - smaller positive number will be negative

One interior angle of a triangle is 60'. The other angle measures are x' and y'. Which of the following could be the values of x
and y? Select all that apply.
A x = 50, y = 90
B. * = 100, y = 20
C. x = 45, y = 45
D. X = 40, y = 80
E. x = 60, y = 60

Answers

Answer:

B. x = 100, y = 20

D. X = 40, y = 80

E. x = 60, y = 60

Step-by-step explanation:

The sum of interior angles of a triangle = 180°

From the above question, one of the angles = 60°

The value for the two other interior angles = 180° - 60° = 120°

Hence, the following options could be the values of x and y is given as x + y = 120

Therefore,

B. x = 100, y = 20

D. X = 40, y = 80

E. x = 60, y = 60

⦁ Convert the vertex form of the equation you wrote above to standard form.

the vertex was ax+b(?)

Answers

Answer:

ax^2 + bx + c

Step-by-step explanation:

im pretty sure this answers your question

The standard form of the vertex form equation is y = 2x² - 12x + 17

How to convert the equation?

The vertex form of a quadratic equation is represented as:

y = a(x - h)² + k

Using the above form, the quadratic equation can be represented as:

y = 2(x - 3)² + 1

Expand

y = 2(x² - 6x + 9) - 1

Further expand

y = 2x² - 12x + 18 - 1

Evaluate the like terms

y = 2x² - 12x + 17

Hence, the standard form of the vertex form equation is y = 2x² - 12x + 17

show all work. what is the measure in degrees of angle A?

Answers

Answer:

∠ A = 62°

Step-by-step explanation:

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

116° is an exterior angle of the triangle, then

3x - 13 + 2x + 4 = 116

5x - 9 = 116 ( add 9 to both sides )

5x = 125 ( divide both sides by 5 )

x = 25

Then

∠ A = 3x - 13 = 3(25) - 13 = 75 - 13 = 62°

The giant panda population in China is increasing at a rate of 1.5% each year. There are 1864 giant panda in 2014. Write a function that models the panda population since 2014.

(exponential growth & decay)

Answers

Given:

Giant panda population in 2014 = 1864

The giant panda population in China is increasing at a rate of 1.5% each year.

To find:

The function that models the panda population since 2014.

Solution:

Since population of giant panda is increasing, therefore the function is the exponential growth model.

The general exponential growth model is:

[tex]P(t)=P_0(1+r)^t[/tex]

Where, [tex]P_0[/tex] is the initial population, r is the growth rate in decimal and t is the time period.

Putting [tex]P_0=1864,r=0.015[/tex], we get

[tex]P(t)=1864(1+0.015)^t[/tex]

[tex]P(t)=1864(1.015)^t[/tex]

Where, t is the number of years since 2014.

Therefore, the required exponential growth model is [tex]P(t)=1864(1.015)^t[/tex].

Ben bought 2 shirts for $16 each, 3 pairs of socks for $2.50 a pair, and a pair of jeans for $37.75. If the sales tax rate is 6.5%, how much did he pay for his items?

Answers

Answer:

Total amount pay by Ben = $82.27 (Approx.)

Step-by-step explanation:

Given:

2 Shirts = $16 each

3 pairs of socks = $2.50 each

1 pair of jeans = $37.75 each

Sales tax = 6.5%

Find:

Total amount pay by Ben

Computation:

Total amount for shirts = 2 x 16

Total amount for shirts = $32

Total amount for socks = 3 x 2.50

Total amount for shirts = $7.50

Total amount before tax = $32 + $7.50 + $37.75

Total amount before tax = $77.25

Total amount pay by Ben = Total amount before tax[1+tax]

Total amount pay by Ben = 77.25[1+6.5%]

Total amount pay by Ben = $82.27 (Approx.)

A game decreased in price by 1/4
After the reduction it was priced at £27.
What was the original price of the game

Answers

Answer:

£36.

Step-by-step explanation:

Because the game was reduced by 1/4

This means that:

£27 = 3/4.

To find 1/3, divide 27 by 3. this gives us 9. Now we know that the game was reduced by £9. To find the original price, instead of taking £9 away, we do the inverse and add the £9. This gives us £36.

You can even check your answer also, as 9 is 1/4 of 36, this proving that the price before the reductio was £36.
