Answer:

4800

Step-by-step explanation:

4773

The 3 is the ones digit.

The 7 to the left of the 3 is the 10s digit.

The 7 (in bold) to the left of the other 7 is the hundreds digit.

1. Make all digits to the right of the hundreds digit 0.

4700

2. We need to find out if we end up with 4700 or 4800.

Since the digit just to the right of the hundreds digit is greater than 4 (it is the tens digit which is a 7), then the hundreds digit 7 must go up 1 to 8.

Answer: 4800

Greatest Common Factor is also shortened as G.C.F . Greatest Common Factor can be used as the greatest or highest number that divides exactly into two or more numbers.

The GCF for the coefficients is 7. Option A is the correct option.

From the question, we are given two terms 7a4b²c² and 14abc⁶

The coefficient for 7a4b²c² = 7

The coefficient for 14abc⁶ = 14

Solving for the GCF,

The factors of 7 are: 1, 7

The factors of 14 are: 1, 2, 7, 14

Then the greatest common factor is 7.

Therefore, the GCF for the coefficients is 7 . Option A is the correct option.

Answer:

domain: -1<x    range:y<-1

Step-by-step explanation:

seeing as how the x value seems to start at -1, but keeps going past that to the right, we can get the equation x>-1.  seeing as how the y value seems to start at -1, but keeps going down, we can get the equation y<-1.

Answer:

option D is correct

Step-by-step explanation:

option D is correct

as, both 2 and 3 are positive integers and also the 2 integer is going towards negative sign but it lies in positive area so,

-2 is in bracket when bracket will be open it will be in positive sign,

so,

2 + 3 - (-2) is correct ans.

Answer:

2m - 5/4 ≤ -7/8

The given inequality can be written as 2m - 5/4 ≤ -7/8.

Inequality is of four types they are

a<b ⇒ a is less than b.

a≤b ⇒ a is less than or equal to b.

a>b ⇒ a is greater than b.

a≥b ⇒ a is greater than or equal to b.

According to the given question

An inequality -7/8 is at most the difference of twice a number m and 5/4 which is 2m - 5/4 ≤ -7/8.

Difference of twice a number 'm' and 5/4 is 2m - 5/4 and this is at most -7/8 means less than or equal to.

∴ The given statement can be written as 2m - 5/4 ≤ -7/8

Answer:

Statement should be : "4 less than the product of 3 and some number x is y" => 3x-4 = y

Step-by-step explanation:

Let "Four less than the product of three and n"

From the given statement we get an algebraic expression 3x - 4 = y.

An algebraic expression in mathematics exists as an expression that stands created up of variables and constants, along with algebraic operations like addition, subtraction, etc. x exists a variable, whose value exists unspecified to us and can take any value.

An algebraic expression exists as an indication acquired by a finite number of the fundamental operations of algebra upon characters symbolizing numbers.

Let "Four less than the product of three and n". From the given statement we get an algebraic expression 3x - 4 = y.

Step-by-step explanation:

i dont know what brainiest means

The maximum or minimum of a quadratic function is found evaluating the polynomial at [tex]x = -\frac{b}{2\cdot a}[/tex].

A quadratic function is an algebraic function of the form:

[tex]y = a\cdot x^{2}+b\cdot x + c[/tex], [tex]\forall \,x, y, a, b, c\,\in \mathbb{R}[/tex] (1)

Where:

The maximum/minimum of a quadratic function is represented graphically by the vertex, which is the only point that has no a "twin" point by any means of symmetry. We can get the x-coordinate of the vertex by means of the quadratic formula:

[tex]a\cdot x^{2} + b\cdot x + (c- y) = 0[/tex] (2)

[tex]x = \frac{-b\pm \sqrt{b^{2}-4\cdot a\cdot (c-y)}}{2\cdot a}[/tex], where [tex]b^{2}-4\cdot a\cdot (c-y) = 0[/tex].

Hence, the x-coordinate of the vertex is:

[tex]x = -\frac{b}{2\cdot a}[/tex] (3)

And the y-coordinate of the vertex is determined by evaluating (1) at (3):

[tex]y = f\left(-\frac{b}{2\cdot a} \right)[/tex] (4)

The maximum or minimum of a quadratic function is found evaluating the polynomial at [tex]x = -\frac{b}{2\cdot a}[/tex].
