Answer:

m = 2

b = 8

Step-by-step explanation:

m, the slope, will be 2. This is because $2 is charged for each topping.

b, the y intercept, will be 8. This is because there is a standard charge of $8 for a cheese pizza without any toppings.

The y intercept can be represented by the point (0, 8), where 0 represents the amount of toppings and 8 represents the price of $8.

So, m = 2 and b = 8

Answer:

∠ DFE = 15°

Step-by-step explanation:

The inscribed angle DFE is half the measure of its intercepted arc, that is

∠ DFE = $\frac{1}{2}$ DE = $\frac{1}{2}$ × 30° = 15°

QUESTION 3<br><br> Find the interest. Round to the nearest cent.<br><br> $1850 at 8% for 14 months

Genrish500 [490]

Answer:

$I=\$172.67$

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the Interest Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem we have

$t=14/12\ years\\ P=\$1,850\\r=0.08$

substitute in the formula above

$I=1,850(0.08(14/12))$

$I=\$172.67$

Line l1 passes through (-2, 5), and (-1, -10)

zalisa [80]

The equations of the lines l1 with points (-2, 5), and (-1, -10) and the line l2 with points (5, 15), and (3, 8), gives the coordinate of the intersection between the lines as the point; (-45/37, -250/37)

<h3>Which method can be used to describe the lines to find the intersection point?</h3>

The slope, m1, of line 1 l1 is found as follows;

m1 = (5 - (-10))/(-2- (-1)) = -15

The equation of line l1 in point and slope form is therefore;

y1 - 5 = -15•(x - (-2))

Which gives;

y1 = -15•(x - (-2)) + 5 = -15•x - 25

y1 = -15•x - 25

The slope, m2, of line 2 l2 is found as follows;

m2 = (15 - 8)/(5 - 3) = 3.5

Equation of line l2 is therefore;

y2 - 15 = 3.5•(x - 5)

Which gives;

y2 = 3.5•(x - 5) + 15 = 3.5•x - 2.5

y2 = 3.5•x - 2.5

At the intersection point, we have;

y1 = y2

Therefore;

-15•x - 25 = 3.5•x - 2.5

18.5•x = -22.5

x = -22.5/18.5 = -45/37

y2 = 3.5•x - 2.5

At the intersection point, we have;

y = y2 = 3.5×(-22.5/18.5) - 2.5 = -250/37

y = -250/37

The coordinates of the intersection between the lines is therefore;

(-45/37, -250/37)
