Answer:

Yes

Step-by-step explanation:

Because In the equation we have 2-2+5x

2-2=0

So, 0+5x = 5x

Eric recorded the number of automobiles that a used car dealer in his town sold in different price ranges. From the Histogram gi

iogann1982 [59]

The correct answer is option A which is the number of cars sold for the price range of $4000 to $4999 will be 15.

<h3>What is a histogram?</h3>

A histogram is a graph for the representation of the data on the plot of the rectangular boxes. It has the data sets on the horizontal and the vertical axes.

As we can see from the histogram data we will conclude that the price range of $4000 to $4999 is shown by the third block and this third block reaches the height of 15.

Therefore the correct answer is option A which is the number of cars sold in the price range of $4000 to $4999 will be 15.

Determine if triangle ABC with coordinates A (0, 2), B (2, 5), and C (−1, 7) is an isosceles triangle. Use evidence to support y

kirill115 [55]

Answer:

The triangle ABC is an isosceles right triangle

Step-by-step explanation:

we have

The coordinates of triangle ABC are

A (0, 2), B (2, 5), and C (−1, 7)

we know that

An isosceles triangle has two equal sides and two equal internal angles

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

$d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}$

step 1

Find the distance AB

substitute in the formula

$d=\sqrt{(5-2)^{2}+(2-0)^{2}}$

$d=\sqrt{(3)^{2}+(2)^{2}}$

$dAB=\sqrt{13}\ units$

step 2

Find the distance BC

substitute in the formula

$d=\sqrt{(7-5)^{2}+(-1-2)^{2}}$

$d=\sqrt{(2)^{2}+(-3)^{2}}$

$dBC=\sqrt{13}\ units$

step 3

Find the distance AC

substitute in the formula

$d=\sqrt{(7-2)^{2}+(-1-0)^{2}}$

$d=\sqrt{(5)^{2}+(-1)^{2}}$

$dAC=\sqrt{26}\ units$

step 4

Compare the length sides

$dAB=\sqrt{13}\ units$

$dBC=\sqrt{13}\ units$

$dAC=\sqrt{26}\ units$

$dAB=dBC$

therefore

Is an isosceles triangle

Applying the Pythagoras Theorem

$(AC)^{2} =(AB)^{2}+(BC)^{2}$

substitute

$(\sqrt{26})^{2} =(\sqrt{13})^{2}+(\sqrt{13})^{2}$

$26=13+13$

$26=26$ -----> is true

therefore

Is an isosceles right triangle

simplify 1/6 divided by 5/9 (Write final answers in lowest terms and mixed numbers, if necessary.) and please explain

Mkey [24]

Answer:

$\frac{3}{10}$

Step-by-step explanation:

to divide 2 fractions follow the procedure

• Leave the first fraction

• Change division to multiplication

• Turn the second fraction upside down

• Simplify by cancelling common factors, if possible

$\frac{1}{6}$ ÷ $\frac{5}{9}$

= $\frac{1}{6}$ × $\frac{9}{5}$ (cancel 6 and 9 by 3 )

= $\frac{1}{2}$ × $\frac{3}{5}$

= $\frac{1(3)}{2(5)}$

= $\frac{3}{10}$ ← in simplest form

The fraction is in simplest form when no factor apart from 1 divides into the numerator/ denominator
