Answer:

5.7-18y=1

Step-by-step explanation:

52-9y=3

5.2-9y=-2

or,57.2-18y=1

Answer:

-18y = 46.8

Step-by-step explanation:

Adding Left hand side elements together as well as right hand side

Eq1 = equation 1

Eq2 = equation 2

LHS(left hand side of the equation)

RHS(right hand side of the equation)

LHS of Eq1 + LHS of Eq2 = RHS of Eq1 + RHS of Eq2

-52 -9y + 5.2 -9y = 3 - 2

=> -9y -9y - 52 + 5.2 = 1

=> -18y - 46.8 = 1

=> -18y - 46.8 = 0

=> -18y = 46.8

Answer:

Infinite solutions

Step-by-step explanation:

So if simplified it would be

-3x+15=15-3x

Which is basically the same thing if arranged

15-3x=15-3x

-3x+15 can also be 15-3x still the same thing as adding 15 to -3x

So since these are equal anything could be used

like try 0

Both get 15

Try 1

Both get 12

Try legit any number

youll get the same results (I would choose 3 positive easy ones, 0,1,2 and 3 negative ones -1,-2,-3)

Answer:

The answer is y = 4x - 8.

Step-by-step explanation:

☆Remember: [tex]m = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

☆Slope-intercept: [tex]y = mx + b[/tex]

---

☆We need to find the slope first. So just plug in according to the slope formula!

[tex]m = \frac{0 - 8}{2 - 4} = \frac{ - 8}{ - 2} = 4[/tex]

---

☆Now we need to find the y-intercept. We are going to plug in the slope and a set of coordinates to find the y-intercept.

[tex]y = mx + b \\ 8 = 4(4) + b \\ 8 = 16 + b \\ \frac{ - 16 = - 16 \: \: \: \: \: \: \: \: \: \: \: \: }{ - 8 = b \: \: \: \: \: \: \: \: \: \: \: \: \: \: } [/tex]

☆Now all we need to do is plug in and we are done!

[tex]y = 4x - 8[/tex]

Step-by-step explanation:

Area of Park = Length * Width

Therefore Width = Area / Length

= (6/8) / (1/2) = (6/8) * (2/1) = 3/2 miles.

Answer:Area of Park = Length * Width

Therefore Width = Area / Length

= (6/8) / (1/2) = (6/8) * (2/1) = 3/2 miles.

Answer:

Step-by-step explanation:

Given:

The line parallel to the given line containing the points (-3,3) and (-2,1).

Also, the parallel line passes through the point (4,1).

We need to determine the equation of the line in slope - intercept form.

Slope:

Since, the two lines are parallel, then their slopes are equal.

Thus, the slope of the parallel line can be determined using the formula,

Substituting the points (-3,3) and (-2,1), we get;

Thus, the slope of the line is

Equation of the line:

The equation of the line can be determined using the formula,

Since, the line passes through the point (4,1), let us substitute the point (4,1) in the above formula, we have;

Thus, the equation of the line is

Hence, y − 1 = −2(x − 4) is the correct answer.

Answer:

y = -3

Step-by-step explanation:

5y + 10/5 = -13 (distribute 5)

5y + 2 = -13 (simplify fraction)

5y = -15 (subtract 2 from both sides)

y = = -3 (divide 5 from both sides)

Checked worked:

5 ([-3] +2/5)

-15 + 10/5

-15 + 2 = -13

y = -3

6.........

The value of algebraic expression [(-8) + ( -9)] + 23 is 6.

Here,

We have to simplify;  the sum of -8 and -9, increased by 23.

And, find an algebraic expression.

What is Algebraic expression?

An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations.

Now,

The written expression is, the sum of -8 and -9, increased by 23.

It can be written as,

⇒ [(-8) + ( -9)] + 23

⇒ - 8 - 9 + 23

⇒ - 17 + 23

⇒ 6

Hence, The value of algebraic expression [(-8) + ( -9)] + 23 is 6.

Answer:

C. [tex]x < -3[/tex] or [tex]x > 1[/tex].

Step-by-step explanation:

Let [tex]f(x) = x^{3}+3\cdot x^{2}-9\cdot x +7[/tex], the first derivate of the function is:

[tex]f'(x) = 3\cdot x^{2}+6\cdot x -9[/tex] (1)

By the Quadratic Formula, we determine the roots of this polynomial:

[tex]x_{1} = 1[/tex], [tex]x_{2} = -3[/tex]

And the factorized form of the polynomial is:

[tex](x-1)\cdot (x+3) > 0[/tex]

By law of Signs, the polynomial is increasing when [tex]x-1 > 0[/tex] and [tex]x +3 > 0[/tex] or [tex]x-1 < 0[/tex] and [tex]x+3 < 0[/tex], which means that:

[tex]x < -3[/tex] or [tex]x > 1[/tex]

Therefore, the right answer is C.

Answer:

The correct option is an option (c).

Given:

The given function is,

[tex]f(x)=x^{3}+3x^{2}-9x+7[/tex]

Computation:

The function is increasing when [tex]f'(x)>0[/tex].

Now, differentiating the given function with respect to [tex]x[/tex] up to first order we get,

[tex]f'(x)=3x^{2}+3(2x)-9(1)+0\\f'(x)=3x^{2}+6x-9\\=3(x^{2}+2x-3)\\=3(x(x+3)-1(x+3))\\=3(x+3)(x-1)[/tex]

So, the sign function is,

 Therefore, [tex]f'(x)>0[/tex] when [tex]x\in (-\infty ,-3)\cup (1,\infty )[/tex]

So, [tex]f(x)[/tex] is increasing on [tex]x<-3[/tex] or [tex]x>1[/tex]

Hence, the correct option is an option (c).
