Step-by-step explanation:

Answer 2

Answer:

a) The vertex will be at (-2, -1), and the parabola will look like a smiley face. 5 points on the parabola would be: (3, 24), (-3, 0), (2, 15), (-1, 0) and (1, 8).

b) The focus will be at (-2, 0), the directrix will be at y = -2, and the axis of symmetry will be at x = -2.

Step-by-step explanation:

a) The vertex (-2, -1) can be found by first setting the parentheses (x+2) equal to zero and solving to get the x value -2, then setting x equal to zero and solving to get the y value of -1.  

The parabola will be pointing up on both ends because the equation for it is positive (given 1 multiplied by parentheses) and it has a degree of 2.

The xy table to find the points would look like this:

x       |         y

3       |      24

-3       |        0

2       |       15

-1        |        0

1        |        8

b) The focus is one unit above the vertex, so the y value increases by 1. The directrix is a line 1 unit below the vertex, so its y value is 1 less than the vertex's. The axis of symmetry is the same as the x value of the vertex with infinite y values.

Anyone know how to do this I need help please

Answers

I assume it is the last one, 3n^2, because the degree is the exponent, which is two and the three is the coefficient, which is next to the variable, plus it is a monomial, so there is only one term, eliminating the first two, the third one is just reversed. Therefore, the answer should be the last one. Hope this helps. :)

Answer:

D

Step-by-step explanation:

mono means one so there must only be one term, the number in front of the variable is the coefficient, n being squared makes it to the second degree

Danny solved the inequality - 8x > 56 and got x>-7. Is this correct and if not, what mistake did Danny
make. Select your decision and reason from the box below.
Is Danny correct? →
YES
OR
NO
56 divided by -8 is not-7
If no, what mistake did Danny make? →
Danny did not reverse the symbol
It should be 7 not-7

Answers

Answer:

Danny did not reverse the symbol.

Hence, the correct answer is: [tex]x<-7[/tex]

Step-by-step explanation:

Given the inequality

[tex]- 8x > 56[/tex]

We know that when we multiply both sides by -1, the 'inequality' gets reverse.

i.e.

[tex]\left(-8x\right)\left(-1\right)<56\left(-1\right)[/tex]

[tex]8x<-56[/tex]

Divide both sides by 8

[tex]\frac{8x}{8}<\frac{-56}{8}[/tex]

[tex]x<-7[/tex]

Therefore, Danny did not reverse the symbol.

Hence, the correct answer is: [tex]x<-7[/tex]

(6 ten thousands 3 hundreds) × 10 =

Answers

Answer:

630000

Step-by-step explanation:

We obtain 603000 when we multiply (6 tens of thousands three hundreds) by 10.

What is meant by standard form?A number is ranked or assigned to the place "ones tens hundreds thousands" when it comes to huge or tiny numbers. The position of numbers is referred to by the place value of a number, which indicates the position of a specific digit in a number that can be ones, tens, hundreds, or thousands.Each digit in a number has a distinct position and value. A number may have multiple digits. Starting from the right, the first digit will be in the ones place, the second in the tens place, and the third in the hundreds place.

Given,

(6 ten thousands three hundreds) × 10

Simplifying the above equation, then we get

= 603000.

Tens of thousands could be used to refer to a bigger sum (typically between 10,000 and 99,999).

What is the most efficient first step to isolate the variable term on one side of this equation?
-9x=-4x+5
a) Subtract 5 from both sides.
b) Add 5 to both sides.
c) Subtract 9x from both sides.
d) Add 4x to both sides

Answers

d is the correct answer
Answer:
D. add 4x to both sides


Explanation:
-9x = -4x + 5
+ 4x + 4x
-5x = 5

-4x and -4x are opposite terms, so they cancel each other out.
Once you add 4x to both sides, the variable term (-5x) is isolated on one side of the equation.

Given:18x-2(3x+1)=5x-16
Prove:x=-2

(Include statements and reasons)

Answers

Answer:

Step-by-step explanation:18x−2(3x+1)=5x−16

18x+(−2)(3x)+(−2)(1)=5x+−16

18x+−6x+−2=5x+−16

(18x+−6x)+(−2)=5x−16

12x+−2=5x−16

12x−2=5x−16

Step 2: Subtract 5x from both sides.

12x−2−5x=5x−16−5x

7x−2=−16
