Step-by-step explanation:

Answer:

vertex = (- 1, 3 )

Step-by-step explanation:

Given a parabola in standard form

y = ax² + bx + c ( a ≠ 0 )

Then the x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

y = 2x² + 4x + 5 ← is in standard form

with a = 2, b = 4, then

[tex]x_{vertex}[/tex] = - [tex]\frac{4}{4}[/tex] = - 1

Substitute x = - 1 into the equation for corresponding value of y, that is

y = 2(- 1)² + 4(- 1) + 5 = 2 - 4 + 5 = 3

vertex = (- 1, 3 )

Answer:

Step-by-step explanation:

[tex]\Rightarrow \: \:\sf\purple{ 2z - 6 = 20}[/tex]

[tex]\Rightarrow \: \:\sf\green{ 2z = 20 + 6}[/tex]

[tex]\Rightarrow \: \:\sf\purple{ 2z = 26}[/tex]

[tex]\Rightarrow \: \:\sf\green{ 2z \div 2 = 20 \div 2}[/tex]

[tex]\Rightarrow \: \:\sf\purple{z = 26 \div 2}[/tex]

[tex]\Rightarrow \: \:\sf\pink{z =13}[/tex]

Answer:

8.760 x 10^3

Step-by-step explanation:

There are 8760 hours in 1 year. So, you can convert this to scientific notation by moving the decimal from 8760 three times to the left:  8760. → 8.760  And since it was moved three times, put an exponent of 3 to the 10:  10^3  So, you get 8.760 x 10^3 hours in a year.

Hope this helps! :)

Answer:

Step-by-step explanation:

set the two equations equal to each other then solve for n

6n + 3 = 4n + 11

2n = 8

n = 4

plug n in for both equations

6(4) + 3

24 + 3 = 27

4(4) + 11

16 + 11 = 27

27 + 27 = 54

the distance is 54

Step-by-step explanation:

Answer:

500

When rounding to the nearest hundred, like we did with 545  we use these rules

first you would have to round the number up to the nearest hundred if the last two digits in the number are 50 or above.

then you would have to   round the number down to the nearest hundred if the last two digits in the number are 49 or below.

lastly you would have to  see if  the last two digits are 00, then we do not have to do any rounding, because it is already to the hundred.

Answer:

x=3

Step-by-step explanation:

3x+4=2x+10

-3       -3

4= -1x+10

-10     -10

-6= -1x

divide by -1

x=6

Thats how you do it

Answer:

x=6

Step-by-step explanation:

first you have to subtract 4 from both sides

3x=2x+10-4

then simplify 2x+10-4 to 2x+6 so you will get

3x=2x+6

-2 -2

(^^you subtract 2x from both sides )

then you get your answer which is x=6
