Answer:

y = (7/4)x + 3

Step-by-step explanation:

(isolate the y variable by moving 7x) 4y = 7x + 12

(divide by 4 to get y by itself) y = (7/4)x + 3

What is the equation of a parabola y(x) that has a vertex at point (− 1/3 , 0.3) and passes through point (− 2/15 , − 1/2 ).

Savatey [412]

bearing in mind that 0.3 = 3/10

$\bf ~\hfill \textit{parabola vertex form}~\hfill \\\\ \begin{array}{llll} y=a(x- h)^2+ k\qquad \leftarrow \textit{we'll use this one}\\\\ x=a(y- k)^2+ h \end{array} \qquad\qquad vertex~~(\stackrel{-\frac{1}{3}}{ h},\stackrel{\frac{3}{10}}{ k}) \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ y=a\left[ x-\left( -\cfrac{1}{3} \right) \right]^2+\cfrac{3}{10}\implies y=a\left( x+\cfrac{1}{3} \right)^2+\cfrac{3}{10}$

$\bf \textit{we also know a point } \begin{cases} x=-\frac{2}{15}\\\\ y=-\frac{1}{2} \end{cases}\implies -\cfrac{1}{2}=a\left( -\cfrac{2}{15}+\cfrac{1}{3} \right)^2+\cfrac{3}{10} \\\\\\ -\cfrac{1}{2}-\cfrac{3}{10}=a\left( \cfrac{1}{5} \right)^2\implies -\cfrac{4}{5}=a\left(\cfrac{1}{25} \right)\implies -\cfrac{4}{5}=\cfrac{a}{25}\implies \cfrac{-4\cdot 25}{5}=a \\\\\\ -4\cdot 5=a\implies \boxed{-20=a} \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill y=-20\left( x+\cfrac{1}{3} \right)^2+\cfrac{3}{10}~\hfill$

I need answer please the answer is not translation

Law Incorporation [45]

Answer:

Dilation

Step-by-step explanation:

A dilation is where the size of the figure changes. The square gets larger and therefore undergoes a dilation.

Other transformations:

In a translation the figure slides or moves from its original position

In a reflection the figure is reflected across a given line

In a rotation the figure is rotated.

The one is the middle please with what x is and an equation

OLga [1]

It is either (5.83 hours and minutes by the way)
$35 \div 6 = 5.83$
or
$35 \div 7 = 5$
if you include the fourth of July this is your answer but if you don't and count the rest of the week then you would get the first one for the hours you work on the fourth of July .......By the way the money does not matter at all in this equation) and check the answer sheet if you need to confirm if the answer is correct.... okay?
