Answer:

Step-by-step explanation:

The term numerical expression is made up of two words, numerical meaning numbers, and expression meaning phrase. ... A numerical expression in mathematics can be a combination of numbers, integers combined using mathematical operators such as addition, subtraction, multiplication, or division.

blsea [12.9K]
N/4 < -1 — we can multiply both sides with 4, so we dont have to deal with fractions.

N < -4

So, our N goes left from -4 on a number line.

-10x<-100 — divide both sides by 10
-x < -10
x > 10

X is from 10 rightwards.

5x>20 — divide both sides by 5
x > 4

X is rightwards from 4.

Which equation could generate the curve in the graph below?
dimulka [17.4K]

Answer:

The answer is option 1.

Step-by-step explanation:

In order to find the equation, you have to apply Discriminant Law, D = b² - 4ac. When D < 0, the equation has no real roots (no x-intercept). When D = 0, it has 2 and equal roots (1 x-intercept). When D > 0, it has 2 distinct roots (2 x-intercept).

Option 1,

y = 3 {x}^{2}  - 2x + 1

D =  {( - 2)}^{2}  - 4(3)(1)

D =  - 8

D < 0

Option 2,

y = 3 {x}^{2}  - 6x + 3

D =  {( - 6)}^{2}  - 4(3)(3)

D = 0

Option 3,

y = 3 {x}^{2}  - 7x + 1

D =  {( - 7)}^{2}  - 4(3)(1)

D = 37

D > 0

Option 4,

y = 3 {x}^{2}  - 4x - 2

D =  {( - 4)}^{2}  - 4(3)( - 2)

D = 40

D  > 0

As you look at the graph, the curve does not meet x-axis so the discriminant must be less than 0.

Point 23 plus brainliest
Oksi-84 [34.3K]

Answer:

The answer is

<h2>4m ( m + 3x) ( m - 2)</h2>

Step-by-step explanation:

4m³ + 12xm² - 8m² - 24xm

Factorize the GCF out

The GCF of 4 , 12 , 8 and 24 is 4

So we have

4( m³ + 3xm² - 2m² - 6xm)

Next factor m out

We have

4m( m² + 3xm - 2m - 6x)

Factorize the terms in the bracket

That's

4m[ m( m + 3x) - 2 ( m + 3x) ]

Next factor ( m + 3x) out

We have the final answer as

<h3>4m ( m + 3x) ( m - 2)</h3>

Hope this helps you
