So... assuming f(x)=x^2-14x+44 then

 f(x)=x^2-14x+44\implies 
\begin{array}{lccclll}
\boxed{1}x^2&\boxed{-14}x&\boxed{+44}\\
\uparrow &\uparrow &\uparrow\\
a&b&c
\end{array}
\\ \quad \\
\textit{vertex of a parabola}\\ \quad \\
y = {{ \boxed{a}}}x^2{{ \boxed{+b}}}x{{ \boxed{+c}}}\\ \quad \\

\left(-\cfrac{{{ b}}}{2{{ a}}}\quad ,\quad  {{ c}}-\cfrac{{{ b}}^2}{4{{ a}}}\right)

The graph shows the cost of some taxi journeys<br><br> work out a formula for c in terms of n
Vitek1552 [10]

Answer:

c=\frac{3}{5}(n)+2.5

Step-by-step explanation:

see the attached figure to better understand the problem

Let

c -----> the cost of some taxi journeys

n ----> the number of miles

we know that

The graph is a line

The equation of a line in slope intercept form is

c=m(n)+b

where

m is the slope

b is the c-intercept (value of c when the value of n is equal to zero)

Observing the graph  we have the points

(0,2.5), (5,5.5)

<em>Find the slope</em>

The formula to calculate the slope between two points is equal to

m=\frac{c2-c1}{n2-n1}

substitute the values

m=\frac{5.5-2.5}{5-0}

m=\frac{3}{5}

we have

b=2.5 -----> because the point (0,2.5) is the c-intercept

substitute in the equation of slope-intercept form

c=\frac{3}{5}(n)+2.5

1. Solve the following equation.(MAFS.8.EE.3.7)<br><br> 5(3x + 7) + 2x = 7x – 5(–2x + 9)
Ksivusya [100]

Answer:

there is no solution

Step-by-step explanation:

Expand.

15x+35+2x=7x+10x-4515x+35+2x=7x+10x−45

2 Simplify  15x+35+2x15x+35+2x  to  17x+3517x+35.

17x+35=7x+10x-4517x+35=7x+10x−45

3 Simplify  7x+10x-457x+10x−45  to  17x-4517x−45.

17x+35=17x-4517x+35=17x−45

4 Cancel 17x17x on both sides.

35=-4535=−45

5 Since 35=-4535=−45 is false, there is no solution.

No Solution
