Write an equation in point-slope form of the line having the given slope that contains the given point. then graph the line

Natali5045456 [20]

Answer:

$y=-\frac{5}{3}x-3$

Step-by-step explanation:

Equation of straight line in point slope form is given a s

$(y-y_1)=m(x=x_1)$

Here

$m=-\frac{5}{2} \ and\ (x_1, y_1)=(0, -3)$

$(y+3)=-\frac{5}{3}(x-0)$

$y=-\frac{5}{3}x-3$

A bookstore makes a profit of $2.50 on each book they sell, and $0.75 on each magazine they sell. One week, the store sold x boo

marin [14]

Answer:

Total books sold=146 books

Total magazines sold=114 magazines

Step-by-step explanation:

Equation 1

Total weekly profit=(Profit for each magazine sold×Number of magazines sold)+(Profit for each book sold×Number of books sold)

where;

Total weekly profit=$450

Profit from each magazine sold=$0.75

Number of magazines sold=y

profit from each book sold=$2.50

Number of books sold=x

Replacing;

450=(0.75×y)+(2.5×x)

0.75y+2.5x=450..... Equation 1

Equation 2

Total number of publications sold=Total number of books sold+Total number of magazines sold

where;

Total number of publications sold=260

Total number of books sold=x

Total number of magazines sold=y

x+y=260... Equation 2

Combine equation 1 and 2 and solve;

1(2.5x+0.75y=450)>>>>>>>>2.5x+0.75y=450

2.5(x+y=260) >>>>>>>>2.5x+2.5y=650

Subtract equation 1 from 2

(2.5x-2.5x)+(2.5y-0.75y)=(650-450)

1.75y=200

y=200/1.75

y=114

Replacing the value for y in equation 2

x+114=260

x=260-114=146

Total books sold=146 books

Total magazines sold=114 magazines

A circle is centered at the point (5,-4) and passes through (-3,2). The equation of this circle is (x+___)²+(y+___)²=____.

JulsSmile [24]

The equation of a circle is:
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the location of the center and r is the radius. So we need to find h, k, and r. The center is given as (5,-4) so h = 5 and k = -4:
(x-5)^2 + (y-(-4))^2 = r^2
(x-5)^2 + (y+4)^2 = r^2
So we need to find r. Use the distance formula to find the distance between (5,-4) and (-3,2):
r = [(5-(-3))^2+((-4)-2)^2]^1/2
r = [8^2 + (-6)^2]^1/2
r = [64 + 36]^1/2
r = 100^1/2
r= 10
The final equation is:
(x-5)^2 + (y+4)^2 = 10^2

Please answer correctly !!!!! Will mark Brianliest !!!!!!!!!!!!!!

andriy [413]

Answer:

44.1

Step-by-step explanation:

Cosine = Adjacent over Hypotenuse

Adjacent of ∠T = 28 and hypotenuse = 39

Which means that $cos(x)=\frac{28}{39}$
