Identify an equation in slope-intercept from for the line parallel to y=-3x + 7 that passes through (2, -4)
alexandr1967 [171]

The slope-intercept form:

y = mx + b

m - slope

b - y-intercept

The parallel lines have the same slope.

We have y = -3x + 7 → m = -3. Therefore y = -3x + b.

Put the coordinates of the point (2, -4) to the equation of a line:

-4=-3(2)+b

-4=-6+b            <em>add 6 to both sides</em>

2=b\to b=2

<h3>Answer: y = -3x + 2</h3>

Marta said 50 + one-half m = 120 is an equation, while Maribel argued that it is an expression. Determine who is correct and exp
In-s [12.5K]

Answer:

Marta

Step-by-step explanation:

We are given that

50+\frac{1}{2}m=120

We have to find who is correct and explain.

We know that

Equation: It is mathematical sentence that combines  numbers and variables which shows the equality of two expressions.

Example:

x+y=3

Expression: It is mathematical phrase that combines  numbers and variables

using mathematical operators.It can be evaluated but not solved.

Example:

x+y

By definitions

50+\frac{1}{2}m=120

It is in equation form.

Therefore, Marta is correct.

Find the zeros of the polynomial function and state the multiplicity of each.
zheka24 [161]
\bf f(x) = 4(x + 7)^2(x - 7)^3\implies 0 = 4(x + 7)^2(x - 7)^3&#10;\\\\\\&#10;0=(x+7)^2(x-7)^3\implies &#10;\begin{cases}&#10;0=(x+7)^7\\&#10;\qquad 0=(x+7)(x+7)\\&#10;\qquad -7=x\\&#10;\qquad -7=x\\&#10;----------\\&#10;0=(x-7)^3\\&#10;\qquad 0=(x-7)(x-7)(x-7)\\&#10;\qquad 7=x\\&#10;\qquad 7=x\\&#10;\qquad 7=x&#10;\end{cases}

the -7 is found there twice, so it has a multiplicity of 2
the +7 is there thrice, so it has multiplicity of 3

Solve the system using substitution:<br> y = -6x + 7<br><br> 3x – 2y = 16<br><br> helppp
bearhunter [10]

Answer:

x=-6 y=-1

Step-by-step explanation:

// Solve equation [2] for the variable  y  

 

 [2]    y = -x - 7

// Plug this in for variable  y  in equation [1]

  [1]    3x - 2•(-x -7) = -16

  [1]    5x = -30

// Solve equation [1] for the variable  x  

  [1]    5x = - 30  

  [1]    x = - 6  

// By now we know this much :

   x = -6

   y = -x-7

// Use the  x  value to solve for  y  

   y = -(-6)-7 = -1  

Solution :

{x,y} = {-6,-1}
