Answer:

22

Step-by-step explanation:

The result of 154 divided by 7 will be 22.

The rules of the division include easy memory tricks that make division calculations easier by generating patterns you may use to deconstruct both simple and complex situations. The guidelines establish requirements that a number must meet in order to neatly divide into another number. While some division rules only require one or two steps to evaluate a number's divisibility, others require two or three steps. Even though some of these formulas are lengthy, division rules help hasten the process of dividing huge numbers.

Remember to continue using the divide, multiply, subtract, and drop-down method for long division problems until all of the dividend's digits have been divided. The solution to the division puzzle is the quotient.

Since the given problem is not a large division. We can solve it by breaking 154 into two parts

    ______

7 / 154     \    2 2

   14

 ---------

   1 4

   14

---------

    0

Therefore, 22 will come from dividing 154 by 7.

Answer:

X intercept is -2

Y intercept is 4

Answer:

The first one, [tex]x[/tex]-intercept [tex]=2[/tex]; [tex]y[/tex]-intercept [tex] = 4[/tex]

Step-by-step explanation:

The [tex]x[/tex]-intercept is where [tex]y=0[/tex], so we can solve for it with the following equation:

[tex]0=4-2x→2x=4→x=2[/tex]

So the answer is the first one, but just to make sure, you can solve for the [tex]y[/tex]-intercept because their [tex]x[/tex]-values always equal to [tex]0[/tex] as well:

[tex]y=4-2(0)→y=4-0→y=4[/tex].

Answer:

y = 4x - 1

Step-by-step explanation:

y + 1 = 4(x + 0)

y = 4x -1

Answer:

y = 4x - 1

Step-by-step explanation:

All you want to do is put the equation into the form y = mx + b where m is the slope and b is the y-intercept (an example would be y = 2x + 1 which would have 2 is the slope and 1 is the y-intercept)

Since you have:

slope or m = 4

y-intercept or b = -1

The equation would be y = 4x - 1

Step-by-step explanation:

Answer:

The expression is a fourth grade trinomial.

Step-by-step explanation:

Mathematically speaking, a polynomial is an equation of the form:

[tex]y = \Sigma_{i = 0}^{n} c_{i}\cdot x^{i}[/tex] (1)

Where:

[tex]y[/tex] - Dependent variable.

[tex]x[/tex] - Independent variable.

[tex]c_{i}[/tex] - i-th Coefficient of the polynomial.

[tex]n[/tex] - Grade of the polynomial

Let [tex]y[/tex] be a fourth-grade polynomial, then the expression must be in the form:

[tex]y = c_{o} + c_{1}\cdot c +c_{2}\cdot c^{2} + c_{3}\cdot c^{3} + c_{4}\cdot c^{4}[/tex] (2)

If we know that [tex]c_{o} = c_{1} = 0[/tex], [tex]c_{2} = 3[/tex], [tex]c_{3} = -10[/tex] and [tex]c_{4} = -1[/tex], then we have the following polynomial:

[tex]y = 3\cdot c^{2}-10\cdot c^{3}-c^{4}[/tex]

By Commutative Property:

[tex]y = -10\cdot c^{3}-c^{4}+3\cdot c^{2}[/tex]

We have a polynomial with three elements.

Therefore, the expression is a fourth grade trinomial.

Following are the calculation on the polynomial equation:

Given:

[tex]-10c^3 - c^4 + 3c^2[/tex]

To find:

degree of the polynomial=?

Solution:

[tex]\to -10c^3 - c^4 + 3c^2[/tex]

In the above given polynomial expression, we use the property of the polynomial expression therefore the degrees of the polynomial is "4".

Answer:

h=3 is the answer

Step-by-step explanation:

The required solution to the given equation 4(h + 1.5) = -6 is

The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question as:

4(h + 1.5) = -6

To solve the equation 4(h + 1.5) = -6, we need to isolate the variable "h". We can do this by performing the following steps:

First, we need to get rid of the parentheses around "h + 1.5". We can do this by multiplying everything inside the parentheses by 4:

4(h + 1.5) = 4h + 6

Next, we need to get rid of the coefficient of 4 in front of "h". We can do this by dividing both sides of the equation by 4:

4h + 6 = -6

h + 1.5 = -1.5

Finally, we can subtract 1.5 from both sides of the equation to isolate the variable "h":

h = -1.5 - 1.5

h = -3

Therefore, the value of "h" that satisfies the equation is -3.
