graph each function y=-x2+5

Answer:

a+2

Step-by-step explanation:

The simplification of the expression 1/2 (2a+4) is a+2. The correct option is B.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

The given expression is 1/2 (2a+4). The expression will be solved as below,

E = 1/2 (2a+4)

E = (2a / 2 ) + ( 4 / 2 )

E = a + 2

Therefore, the simplification of the expression 1/2 (2a+4) is a+2. The correct option is B.

Answer:

Part 1: 61 degrees Part 2: 90 degrees

Step-by-step explanation:

m<a = 180 - m<b - m<c - 29

m<c = 29

m<b = 90-29

m<b = 61

m<a = 180 - 61 -29 -29

m<a = 61 degrees

m<c + m<b = 29 + 61

m<c + m<b 90 degrees

Answer:

false the |-| mean the absolute value thus it would = the same

Answer: False

Answer:

4.9

Step-by-step explanation:

first step is to add up 44 and 77, to get 121

the goal is to get a value of 180 degrees, so taking the info we have gathered lets do 180-121 to give us 58

58 minus 9 is 49 and divide by ten the decimal gives us

4.9

10 times 4.9 is 50 plus 9 makes 58

Answer:

[tex](-\frac{2}{7},-\frac{65}{7} )[/tex]

Step-by-step explanation:

By steps in the image:

Step 1:

To eliminate, you need one of the coefficients to be the same in both equations. We will use the term "-6x" found in the first equation.

To get this, multiply the entire second equation by 6 and simplify using the distributive property. The new equation is:

[tex]6x-6y=54[/tex]

Step 2:

Now you need to subtract the first equation and the new version of the second equation. By doing this, the "-6x" in both equations will cancel each other out.

Step 3:

Solve for x in the given equation by:

Step 4:

Solve for y by:

Solution:

Answer:

350 hamburgers

Step-by-step explanation:

x = hamburgers

y = cheeseburgers

x + y = 750

y = x + 50

Using substitution:

x + (x + 50) = 750

2x + 50 = 750

2x = 700

x = 350

y = 350 + 50 = 400

Answer:

t=9.48n+119.88

Step-by-step explanation:

where t is the total cost of 12 t-shirts, and n is the number of words in the design

0.75n+9.99 is the equation for custom made t-shirts, and n represents the number of words in the design

t=12(0.75n+9.99)

where t is the total cost of t-shirts, and n is the number of words in the design

When simplified, this becomes t=9.48n+119.88
