Equivalent expressions are expressions with equal values
The equivalent expression of 2(14x-3y+28x+12.2-5y-17.5) is 84x-16y-10.6
The expression is given as:
2(14x-3y+28x+12.2-5y-17.5)
Collect like terms
2(14x-3y+28x+12.2-5y-17.5) = 2(14x+28x-3y-5y+12.2-17.5)
Evaluate the like terms
2(14x-3y+28x+12.2-5y-17.5) = 2(42x-8y-5.3)
Open the bracket
2(14x-3y+28x+12.2-5y-17.5) = 84x-16y-10.6
Hence, the equivalent expression of 2(14x-3y+28x+12.2-5y-17.5) is 84x-16y-10.6

Answer:
[tex]b=-\frac{-mx-2x+2m-60}{x};\quad \:x\ne \:0[/tex]
Step-by-step explanation:
Given the expression
[tex]\left(x-2\right)\left(x-m\right)=x^2-bx+60[/tex]
switch sides
[tex]x^2-bx+60=\left(x-2\right)\left(x-m\right)[/tex]
subtract x² from both sides
[tex]x^2-bx+60-x^2=\left(x-2\right)\left(x-m\right)-x^2[/tex]
simplify
[tex]-bx+60=-mx-2x+2m[/tex]
subtract 60 from both sides
[tex]-bx+60-60=-mx-2x+2m-60[/tex]
simplify
[tex]-bx=-mx-2x+2m-60[/tex]
subtract x from both sides; x≠0
[tex]\frac{-bx}{-x}=-\frac{mx}{-x}-\frac{2x}{-x}+\frac{2m}{-x}-\frac{60}{-x};\quad \:x\ne \:0[/tex]
simplify
[tex]b=-\frac{-mx-2x+2m-60}{x};\quad \:x\ne \:0[/tex]
Thus,
[tex]b=-\frac{-mx-2x+2m-60}{x};\quad \:x\ne \:0[/tex]

Choose the point-slope form of the equation below that represents the line that passes through the point (−1, 6) and has a slope of −3.
Answer:
y - 6 = - 3(x + 1)
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Here m = - 3 and (a, b) = (- 1, 6) , then
y - 6 = - 3(x - (- 1) ) , that is
y - 6 = - 3(x + 1)
Answer:
your answer would be y - 6 = - 3(x + 1)

Solve for x
5x – 7 = 19
Give your answer as an

5x - 7 = 19
Add 7 to both sides:
5x = 26
Divide both sides by 5:
x = 26/5
[tex]5x - 7 = 19[/tex]
Move -7 to another side and become + 7. Whenever we move to another side, we change the sign/operator to opposite. Ergo, changing from plus to minus and multiply to divide.
[tex]5x = 19 + 7 \\ 5x = 26[/tex]
We are at this part. Now to move 5 which is multiplying the x. So we move 5 from multiply to divide 26.

Ergo, the answer is x = 26/5

Write an equation in slope-intercept form that describes the line with a slope of -2 and (5,4) is on the line
Answer:
The equation in slope-intercept form will be:
y = -2x + 14Step-by-step explanation:
Given
slope = m = -2point (5, 4)We know that the slope-intercept form of the line equation is
[tex]y = mx+b[/tex]
where m is the slope of the line and b is the y-intercept
substituting m = -2 and the point (5, 4) in the slope-intercept form to get the y-intercept 'b'
y = mx+b
4 = -2(5) + b
4 = -10 + b
b = 4+10
b = 14
now substituting m = -2 and b = 14 in the slope-intercept form to get the equation in slope-intercept
y = mx+b
y = -2x + 14
Therefore, the equation in slope-intercept form will be:
y = -2x + 14need help solving [(-3)*(-2)⁹⁹-(-4)*(-2)⁹⁹]/2⁹⁶. I need a step by step guide too, please.

Step-by-step explanation:
Exponentiation: (-2) ^ 99 = -6.3382530011411×1029
Multiple: -3 * the result of step No. 1 = -3 * (-6.3382530011411×1029 ) = 1.9014759003423×1030
Exponentiation: (-2) ^ 99 = -6.3382530011411×1029
Multiple: -4 * the result of step No. 3 = -4 * (-6.3382530011411×1029 ) = 2.5353012004565×1030
Subtract: the result of step No. 2 - the result of step No. 4 = 1.9014759003423×1030 - 2.5353012004565×1030 = 1.9014759003423×1030 - (2.5353012004565×1030 ) = -6.3382530011411×1029

Use the drawing tool(s) to form the correct answer on the provided graph.
Graph the solution to this system of inequalities in the coordinate plane.
3y>2x=+12
2x+y≤-5
Answer:
We have the system:
3y>2x+12
2x+y≤-5
The first step will be to write the inequalities as lines:
y > (2x + 12)/3
y ≤ -5 - 2 x
Now that the equations are written in slope-intercept form, we just need to draw the lines.
In the first case, we have the symbol ">", which means that the line will be a dashed line, and the shaded area will be above that line.
In the second equation we have the symbol "≤", this means that the line will be a solid line, and the shaded area will be below that line.
The graph of both inequalities is shown below. Where the solution to the system is the double shaded area.
Answer:
Thanks to Facundo doing all the work, all I did was plug in the numbers on a graphing calculator.
Step-by-step explanation:
Using the graphing calculator, "y>(2x+12)/3" has points at (-6,0) and (0, 4) and isn't shaded because there isn't a line under the greater than/less than sign.
Using the graphing calculator again, we plug in the inequality "y≤-5-2x". This has points at (-5, 0) and (0, -5) and is shaded because there is a line under the greater than/less than sign. A picture of this is attached.
Again, thank you Facundo. Refer to his explanation to find out how to make the inequalities lines.

What is the equation of the line that passes through the point (-6,2)(−6,2) and has a slope of -3/2?
Given:
A line passes through the point (-6,2) and has a slope of [tex]-\dfrac{3}{2}[/tex].
To find:
The equation of line.
Solution:
If a line passes though a point [tex](x_1,y_1)[/tex] and has a slope m, then the equation of line is
[tex]y-y_1=m(x-x_1)[/tex]
The line passes through the point (-6,2) and has a slope of [tex]-\dfrac{3}{2}[/tex]. So, the equation of line is
[tex]y-2=-\dfrac{3}{2}(x-(-6))[/tex]
[tex]y-2=-\dfrac{3}{2}(x+6)[/tex]
[tex]y-2=-\dfrac{3}{2}(x)-\dfrac{3}{2}(6)[/tex]
[tex]y-2=-\dfrac{3}{2}(x)-9[/tex]
Add 2 on both sides.
[tex]y=-\dfrac{3}{2}(x)-9+2[/tex]
[tex]y=-\dfrac{3}{2}x-7[/tex]
Therefore, the equation of line is [tex]y=-\dfrac{3}{2}x-7[/tex].

find a parametric representation of the solution set of the linear equation. (enter your answer as a comma-separated list of equations. use t as your parameter.)
To represent the solution set of a linear equation parametrically, we introduce other parameters like s and t for the free variables.
Every linear equation has n - 1 free variables where n is the number of variables.
For x + y + z = 2, we have 3 variables and 3 - 1 = 2 free variables.
First, let y and z be the free variables, we first solve the linear equation for x to get:
x = 2 - y - z
Therefore , the parametric representation of the solution set is given by :
x = 2 - s -t
y = s
z = t
