Answer:

x = 5 Or x = \frac{5}{2}

2

5

Explanation:

Given \frac{x-1}{x-2}+\frac{x-3}{x-4}=\frac{10}{3}

x−2

x−1

+

x−4

x−3

=

3

10

\implies \frac{(x-1)(x-4)+(x-3)(x-2)}{(x-2)(x-4)}=\frac{10}{3}⟹

(x−2)(x−4)

(x−1)(x−4)+(x−3)(x−2)

=

3

10

\implies \frac{x^{2}-4x-x+4+x^{2}-2x-3x+6}{x^{2}-4x-2x+8}=\frac{10}{3}⟹

x

2

−4x−2x+8

x

2

−4x−x+4+x

2

−2x−3x+6

=

3

10

\implies \frac{2x^{2}-10x+10}{x^{2}-6x+8}=\frac{10}{3}⟹

x

2

−6x+8

2x

2

−10x+10

=

3

10

\implies 3(2x^{2}-10x+10)=10(x^{2}-6x+8)⟹3(2x

2

−10x+10)=10(x

2

−6x+8)

\implies 6x^{2}-30x+30=10x^{2}-60x+80⟹6x

2

−30x+30=10x

2

−60x+80

\implies 0= 10x^{2}-60x+80-6x^{2}+30x-30⟹0=10x

2

−60x+80−6x

2

+30x−30

\implies 4x^{2}-30x+50=0⟹4x

2

−30x+50=0

Divide each term by 2 ,we get

\implies 2x^{2}-15x+25=0⟹2x

2

−15x+25=0

Splitting the middle term,we get

\implies 2x^{2}-10x-5x+25=0⟹2x

2

−10x−5x+25=0

\implies 2x(x-5)-5(x-5)=0⟹2x(x−5)−5(x−5)=0

\implies (x-5)(2x-5)=0⟹(x−5)(2x−5)=0

\implies x-5 = 0 \: Or \: 2x-5 = 0⟹x−5=0Or2x−5=0

\implies x = 5 \: Or \: x=\frac{5}{2}⟹x=5Orx=

2

5

Therefore,

x = 5 Or x = \frac{5}{2}

A city manager made a scatter plot of the number or retail store in a certain city over the years. the scatter plot had a trend
Fiesta28 [93]

Answer:

155

Step-by-step explanation:

The problem sounds complicated, but it's not. Let's analyse.

The city manager have come up with an equartion y=11x +12, with Y is the total number of the stores and X stands for how long it has been since 2003.

We can't explain how the manager came up with this equation, so iwe don't need to think of if the equation is real or not. Let's just base on what we have.

Because the equation aboce is a trendy line, it means that it would likely to be true with any X ( number of years since 1990).

In Tracy's case, the year is 2003, so it has been 2003 - 1990 = 13 years since 1990. This is the X in the equation. Now we only need to find Y in the equation, which is the number of retail stores there were in 2003, exactly what the problem asks.

y= 11x + 12

=> In Tracy's case: y= 11*13 + 12= 155

So the number of retail stores there were in 2003 was 155

Math help ;x please help <br> asap skdsk <br> 10 points!
Svetradugi [14.3K]

Answer:

C.

Step-by-step explanation:

When you write the equation of a line in slope-intercept form,

y = mx + b,

m is the slope.

Parallel lines have equal slopes.

The given line is

y = (4/5)x - 1

and has slope 4/5.

The only equation in the choices with slope 4/5 is in choice C whose line is

y = (4/5)x + 2.
