Answer:

c. Identity property

Step-by-step explanation:

edg 2020

Identity property is used in the equation a+bi+0+0i=a+bi.

The identity property of addition says that the sum of 0 and any number is that number only.

We have been given the following equation

a+bi+0+0i=a+bi

when we multiply it with 0 we get 0 and the equation becomes

a+bi=a+bi

It shows the identity property of addition.

Answer:

A= 48°

B= 60°

C= 72°

D= 20°

E= 20°

F= 160°

G= 160°

Step-by-step explanation:

A= 180° -90° -42° (∠ sum of △)

A= 48°

D= 180° -42° -28° -90° (∠ sum of △)

D= 20°

E= D (vert. opp. ∠s)

E= 20°

G= 180° -D (adj. ∠s on a str. line)

G= 180° -20°

G= 160°

F= G (vert. opp. ∠s)

F= 160°

C= 180° -88° -D (∠ sum of △)

C= 180° -88° -20°

C= 72°

A +B +C= 180° (adj. ∠s on a str. line)

48° +B +72°= 180°

B +120°= 180°

B= 180° -120°

B= 60°

Answer:

The third answer

Step-by-step explanation:

Each angle on both triangles has a set of lines, either one, two, or three. These lines are used to show congruency over a number of lines or angles. So one angle will correlate with whatever other angles have that same number of lines. For example, e and g both have two lines, this means they are corresponding and congruent.

Step-by-step explanation:

18 + 18 = 36

36 + 24 = 60

60 + 18 = 78

78 + 24 = 102

102 + 18 = 120

There are two total long-sleeve shirts and four total short-sleeve shirts.

Statements to Equations Conversion and the Other Way Around

Cost of 1 short-sleeve shirt: $18.

Cost of one long-sleeve shirt: $24.

Purchase 2 more short-sleeve shirts than long-sleeve shirts, and the total cost will be $120.

Assuming 2 long sleeves and 4 short sleeves, we get 120, or 2*24 + 4*18 = 120.

He purchased two long-sleeve shirts and four short-sleeve shirts after the condition was met.

Additionally, the requirement of 2 more short-sleeve shirts than long-sleeve shirts is met.

Answer: The slope is 3/2  or 1.5

Step-by-step explanation:

The line is going through the origin meaning that the slope will be the coordinate of one of the points divided by its y coordinate.  

One point that can be found on the line is  (2,3)

Divide the y coordinate by the x coordinate to find the slope.

The y coordinate is 3 and the x coordinate is 2.

3/2 = 1.5

The slope is 3/2  or 1.5.

46.2 doughnuts is equal to 3.85 dozens

Answer:

Let the number be x

According to the question,

6x -7 = 35

=> 6x = 35 + 7

=> x = 42/6

=> x = 7

The solution to the equation is x = 7.

We have,

Let's assume the unknown number is represented by the variable 'x'.

- Translate the given information into an equation:

6x - 7 = 35.

- To isolate the variable 'x', start by adding 7 to both sides of the equation:

6x - 7 + 7 = 35 + 7.

- Simplify:

6x = 42.

- Next, divide both sides of the equation by 6 to solve for 'x':

(6x)/6 = 42/6.

x = 7

Therefore,

The solution to the equation is x = 7.

Answer:

Step-by-step explanation:

f(x) = –|x + 3| is a case of the absolute value function

f(x) = -|x - {a}| + c, where (a, c) is the vertex.  Comparing them, we see that

the value of a must be -3 and that of c must be 0.

Thus, the vertex of the graph is at (-3, 0), and the graph opens up; it looks like a "v" shape.

Answer:

speed of Jada = 6km per hour which is not equal to

speed of Andre = 8km per hour

They did not run at same speed

Step-by-step explanation:

formula of speed = distance covered/ time taken

For Andre

Distance = 2 KM

time = 15 mins

60 mins = 1 hour

15 mins = 1/60 * 15 hour = 0.25 hours

thus,

speed = 2km/0.25 hour = 8 km per hour

Similarly for Jada

Distance = 3 KM

time = 20 mins

60 mins = 1 hour

20 mins = 1/60 * 20 hour = 1/3 hours

thus,

speed = 2km/(1/3)hour = 6  km per hour

Now we have

speed of Jada = 6km per hour which is not equal to

speed of Andre = 8km per hour

Answer:

=−16x+8 for -2(8x-4)

Step-by-step explanation:

What is the solution to -2(8x-4)= -8x

What is the solution to 2x+5= 7x

so that means -2(8x-4) is less than 2x+5.

Answer: x > 1/6

Step-by-step explanation:

-2(8x - 4) < 2x + 5

Distribute:

-16x + 8 < 2x + 5

Subtract 2x from both sides:

-18x + 8 < 5

Subtract 8 from both sides:

-18x < -3

Divide both sides by -18:

x > 3/18 BUT this simplifies to:

x > 1/6

The reason the inequality flipped is because you divided both sides by a negative number.

The inequality ONLY flips when you divide or multiply both sides by a NEGATIVE number.
