Find an equation for the line with the given properties,express the equation in slope-intercept form. p=(-3,5) and q=(-2,3)

1 answer:

8 0

(-3,5)(-2,3)
slope = (3 - 5) / (-2 - (-3) = -2 / 1 = -2

y = mx + b
slope(m) = -2
use either of ur points...(-2,3)....x = -2 and y = 3
now we sub and find b, the y int
3 = -2(-2) + b
3 = 4 + b
3 - 4 = b
-1 = b

so ur equation is : y = -2x - 1 <==

Classify each pair of numbered angles. Drag and drop the descriptions into the boxes to correctly classify each pair of numbered

Leona [35]

(i) Pairs of neighboring angles are supplementary and opposite angles have the same measure.

(ii) The two angles formed by a line coming out of another line are supplementary.

<h3>How to analyze pairs of angles</h3>

(i) When two straight lines pass through each other, then two pairs of opposite angles are constructed. A pair with angles of $(3\cdot x + 52)^{\circ}$ and another pair with angles of $(2\cdot x + 2)^{\circ}$ , each pair of angles with different measures are supplementary. $\blacksquare$

(ii) When a straight line comes out of another straight line, from a point distinct to any endpoint of the former, then we construct two supplementary angles. The largest angle has a value of $(10\cdot x + 20)^{\circ}$ , whereas the smaller one has a value of $(6\cdot x + 8)^{\circ}$ . $\blacksquare$

The cash drawer of the market contains $227. There are six more $5 bills than $10 bills. The number of $1 bills is two more than

k0ka [10]

Answer:

There are 122 one dollar bills, 11 five dollar bills and 5 ten dollar bills.

Step-by-step explanation:

There are bills of one dollar, five dollars and ten dollars on the cash drawer, therefore the sum of all of them multiplied by their respective values must be equal to the total amount of money on the drawer. We will call the number of one dollar bills, five dollar bills and ten dollar bills, respectively "x","y" and "z", therefore we can create the following expression:

$x + 5*y + 10*z = 227$

We know that there are six more 5 dollar bills than 10 dollar bills and that the number of 1 dollar bills is two more than 24 times the number of 10 dollar bills, therefore:

$y = z + 6\\x = 2 + 24*z$

Applying these values on the first equation, we have:

$2 + 24*z + 5*(z + 6) + 10*z = 227\\2 + 24*z + 5*z + 30 + 10*z = 227\\39*z + 32 = 227\\39*z = 227 - 32\\39*z = 195\\z = \frac{195}{39}\\z = 5$

Applying z to the formulas of y and x, we have:

$y = 5 + 6 = 11\\x = 2 + 24*5 = 122$

There are 122 one dollar bills, 11 five dollar bills and 5 ten dollar bills.
