Answer:

16x -12y = 4

15x +12y = 27

Step-by-step explanation:

4x-3y = 1

5x+4y=9

Multiply the first equation by 4

16x -12y = 4

Multiply the second equation by 3

15x +12y = 27

Answer:

16x - 12y = 4

15x + 12y = 27

Step-by-step explanation:

In order to eliminate the y terms, the equations must be manipulated in order to make the coefficient of the y-term equal 0 when the equations are added.

In this case, we are trying to make one equation with -3y and another equation with 4y result in a single equation with 0y.

We can do this by multiplying the first equation by 4 and the second equation by 3 to result in -12y and 12y. When these are added, the sum is 0y.

4 * (4x - 3y = 1) = 16x - 12y = 4

3 * (5x + 4y = 9) = 15x + 12y = 27

The resulting equations are

16x - 12y = 4

15x + 12y = 27

A circle is centered at the point (-3, 2) and passes through the point (1, 5). The radius of the circle is ______ units. The poi
nalin [4]
Circle formula
(x-h)^2+(y-k)^2=r^2 where (h,k) is the center
and r=radius

to find the radius
we are given one of the points and the center
distnace from them is the radius
distance formula
D=\sqrt{(x2-x1)^{2}+(y2-y1)^{2}}
points (-3,2) and (1,5)
D=\sqrt{(1-(-3))^{2}+(5-2)^{2}}
D=\sqrt{(4)^{2}+(3)^{2}}
D=\sqrt{16+9}
D=\sqrt{25}
D=5

center is -3,2
r=5
input
(x-(-3))^2+(y-2)^2=5^2
(x+3)^2+(y-2)^2=25 is equation
radius =5
input -7 for x and solve for y
(-7+3)^2+(y-2)^2=25
(-4)^2+(y-2)^2=25
16+(y-2)^2=25
minus 16
(y-2)^2=9
sqqrt
y-2=+/-3
add 2
y=2+/-3
y=5 or -1

the point (-7,5) and (7,-1) lie on this circle



radius=5 units
the points (-7,5) and (-7,1) lie on this circle

Carl wants to buy a television that cost $500 including taxes to pay for the television he will use a payment plan that requires
ozzi

Answer:

41%

Step-by-step explanation:

Given the cash price is $500, the hire purchase price is calculated by summing the installment and down-payment:

Hire \ Purchase \ Price=Installments +Downpayments\\\\=8\times 72.50+125\\\\=705

#Percentage increase in price is the difference between the hire purchase price and list price as a percentage of the list price:

\bigtriangleup Price=705-500\\\\=205\\\\\%\bigtriangleup Price=\frac{\bigtriangleup Price}{500}\times 100\%\\\\\\=\frac{205}{500}\times100\%\\\\=41\%

Hence, the % increase in price is 41%
