Hello,

$\widehat{ABD}=\frac{180-40}{2}$ =70 (sum of angles of a triangle=180°)

$\widehat{ABE}=180-70=110$ supplementary angles

$\widehat{ABE}=\widehat{DCF}$ translation BC

$\widehat{BCF}=110-40=70$ image of the angle DAB by the axis symmetry DB

$\widehat{BCF}=\widehat{BEF}$ opposed angles of a parallelogram
are supplementary.

$\widehat{BEF}=\widehat{HEG}$ opposed angles by the vertex

$\widehat{HEG}=\widehat{IHE}=70$ alterne-interne angles (sorry for the words English is difficult for me)

primo car rental agency charges $33 per day plus $0.20 per mile. ultimo car rental agency charges $17 per day plus $0.85 per mil

belka [17]

Let's assume m represent the mileage of the car.

Given that, Primo car rental agency charges $33 per day plus $0.20 per mile.

So, the total charge for this agency = 33 + 0.20m.

Similarly total charge of the ultimo car = 17 + 0.85m.

Now we need to find the daily mileage for which the ultimo charge is four times the primo charge . So, we can set up an equation as following:

17 + 0.85m = 4 *( 33 + 0.20m )

17 + 0.85m = 132 + 0.80m By distribution property.

17 + 0.85m -0.80m = 132 + 0.80m -0.80m Subtract 0.80m from each sides.

17 + 0.05m = 132

17 + 0.05m - 17 = 132 - 17 Subtract 17 from each sides.

0.05m = 115

$\frac{0.05m}{0.05} =\frac{115}{0.05}$ Divide each by 0.05.

So, m = 2300

Hence, the daily mileage is 2300 miles.

Hope this helps you!

graph the parabola y equals negative x squared + 3 to graph a parabola plot the vertex and four additional points two on each si

Nataliya [291]

You don't have the graph icon here, so we'll have to graph this parabola without it.

Your parabola is y = -x^2 + 3., which resembles y = a(x-h)^2 + k. We can tell immediately that this parabola opens down and that the vertex is (0,3).

Plot (0,3). Besides being the vertex, this point is also the max. of the function.

Now calculate four more points. Choose four arbitrary x-values, such as {-2, 1, 4, 5} and find the y value for each one. Plot the resulting four points. Draw a smooth curve thru them, remembering (again) that the vertex is at (0,3) and that the parabola opens down.
