20 PINTS PLEASE HELP!
If another equation is graphed so that the system has one solution, which equation could that be?
O y = 2(x+1)
O y = 2(x-1)
O y = 2(x-2)
O y=-2(x+1)

Answer:

Let's solve for f.

x=5+4(x−4)f(7)

Step 1: Flip the equation.

28fx−112f+5=x

Step 2: Add -5 to both sides.

28fx−112f+5+−5=x+−5

28fx−112f=x−5

Step 3: Factor out variable f.

f(28x−112)=x−5

Step 4: Divide both sides by 28x-112.

f(28x−112)28x−112=x−528x−112

f=x−528x−112

Answer:

f=x−528x−112

Step-by-step explanation:

.. 3 + 2[4(2) – (4 + 3(2))]. 3 + 2[8 – (4 + 6)]. 3 + 2[8 – (10)]. 3 + 2[–2]. 3 – 4. –1 ... 2x + 6 = 4 – 2 + 1x. 2x + 6 = 2 + x. 2x – x + 6 = 2 + x – x. x + 6 = 2. x + 6 – 6 = 2 – 6. x = –4.

Answer:

57.14% increase

Step-by-step explanation:

$350÷$200(amount of increase) = 0.5714

0.5714×100= 57.14%

Answer:

Step-by-step explanation:

1). Let the equation of the line is,

  y = mx + b

  Here, m = slope of the line

  b = y-intercept

  Slope of a line passing through two points,

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

  We take two points from the table given (-3, -19) and (0, -1)

  m = [tex]\frac{-19+1}{-3-0}[/tex]

  m = 6

  y - intercept 'b' = -1 [For x = 0]

  Therefore, equation of the line will be,

  y = 6x - 1

2). Equation of a line passing through a point (x', y') is,

   y - y' = m(x - x')

   Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is,

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

   We take two points from the given table as (2, 12) and (3, 18).

   Slope of the line passing through these points will be

   m = [tex]\frac{18-12}{3-2}[/tex] = 6

   Equation of the line passing through (2, 12) will be,

   y - 12 = 6(x - 2)

   y = 6x - 12 + 12

   y = 6x

By using a graphing tool we can graph these lines representing the tables.

Answer:

Up 2, right 5

Step-by-step explanation:

Step-by-step explanation:

[tex]v = {x}^{3} \\ {v}^{2} + 3v - 5 = 0 \\ [/tex]

Solving this equation using the quadratic formula, we get two real solutions :

1.1926 or -4.1926

Now we know the values of v , we can calculate x since x is ∛ v

[tex] {x}^{6} + 3 {x}^{3} - 5 = 0[/tex]

[tex]x = \sqrt[3]{1.1926} = 1.0605 \\ x = \sqrt[3]{ - 4.1926} = - 1.6125[/tex]

Answer:

4

Step-by-step explanation:

Answer:

C

Step-by-step explanation:

You have to distribute the negative into the second set of parentheses first, and since 2x is positive, it will be negative, -3 is negative so it will be positive, and 18 is positive so it will be negative

Answer: 19 people

Step-by-step explanation:

If every 4th customer received a free gingerbread man cookie and 29 cookies were given away then the number of customers that came were:

= 4 * 29

= 116 customers

Because 116 customers came, they were able to give 29 cookies by giving one to every 4th customer.

If there were 116 customers, the number of customers who got the free candy canes would be:

= 116/6

= 19.3

= 19 people

Answer:

y=-2x+17

Step-by-step explanation:

So the problem is 2x+y=17, we know that slope intercept form is y=mx+b where m is the slope and b is the y-int.

All you have to do is isolate the y.

2x+y=17

-2x on both sides so you can leave the y alone.

y=-2x+17 should be the answer. Hope this helps!

Answer:

31.11

Step-by-step explanation:

simplify the expression

Answer:

Step-by-step explanation:

1st use the two points to find the slope of the line that passes thru those two points

m = y2 - y1 / x2  - x1    

where point1 = ( x1, y1 )  and point2 = (x2, y2 )

your are given P1 = ( -2,10)  and P2 = (1,1)

find the slope

m = 1-(-2) / 1-10

m = 1+2 / -9

m = 3 / -9

m = - 1/3

then use the point-slope formula [y-y1 = m(x-x1)] with either of the two points, I'll use P2 b/c it seems easier (1,1) , you get the same results with either point and work the problem to the slope-intercept form [y = mx +b ]

y -y1 = m(x-x1)

y-1 = -1/3(x-1)

y-1 = -1/3x + 1/3

y = -1/3x + 1/3 + 1

y = -1/3x + 4/3

Answer:

$275

Step-by-step explanation:

30% + 15%=45%

45% of 500 is 225, because 500 x 0.45=225. Then subtract the discount from the total, 500 - 225, and you get 275
