Answer:

<E = <A

Step-by-step explanation:

If <D maps onto <B the triangles are similar

CDE is similar to CBA

That means The angles are congruent and the sides are proportional

<C = <C

<D = <B

<E = <A

The sides are not congruent but proportional (In a ratio)

CD CE DE

----- = ------ = -----

CB CA BA

C
The two triangles are similar — that is, the three angles in triangle EDC correspond to those in ABC

Alla [95]

Answer: 1,296 m iles

Step-by-step explanation:

Hi, to answer this question we have to apply the next formula:

Distance = Speed rate x time

speed rate = 54 miles per hour
time = 24 hours

Replacing with the values given and solving for D (distance)

D = 54 mph x 24 h = 1,296 m

The car traveled 1,296 miles

aev [14]

Answer/Step-by-step explanation:

✍️The equation of the line in point-slope form:

The equation is given as $y - b = m(x - a)$ , where,

(a, b) = a point on the line.

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1}$

Let's find the slope (m) of the line, housing (3, 21) and (6, 12):

$slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 21}{6 - 3} = \frac{-9}{3} = -3$

Substitute a = 3 and b = 21, m = -3 into $y - b = m(x - a)$ .

Thus, the point-slope equation would be:

✅ $y - 21 = -3(x - 3)$

✍️The equation of the line in slope-intercept form:

Rewrite $y - 21 = -3(x - 3)$ , so that y is made the subject of the formula.

$y - 21 = -3x + 9$

Add 21 to both sides

$y = -3x + 9 + 21$

$y = -3x + 30$

✅The slope-intercept equation of the line is $y = -3x + 30$

Where,

-3 = how much did his delivery time decrease per day (slope)

30 = how long it initially took Peter to deliver his packages (y-intercept)

IGNORE THE SQUARE ON THE GRAPH
a trapezium is a quadrilateral with parallel sides
see how you could draw that
and match the coordinate to the y in (-3,3) and then use the reciprocal of -3 as the x coordinate
your final plot points would be (3,3)
plot this point and join up your coordinates.
