9x+35=-5y slope intercept form

german

Answer:

y = - $\frac{9}{5}$ x - 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Given

9x + 35 = - 5y ( add 5y to both sides )

5y + 9x + 35 = 0 ( subtract 9x + 35 from both sides )

5y = - 9x - 35 ( divide all terms by 5 )

y = - $\frac{9}{5}$ x - 7 ← in slope- intercept form

Reshawn is buying 3 books in a trilogy set for $24.81. He will save $6.69 by buying the trilogy set instead of buying individual

gulaghasi [49]

$10.50

Let x be the cost of the individual books. Then 24.81=3x−6.69

3x= 24.81+ 6.69 =31.50

x=31.50/3=10.50

A can of beans has surface area 337 cm2. It's heights is 11cm. What is the radius of the circular top?

Karolina [17]

Answer:

3.66 cm

Step-by-step explanation:

r = Radius of cylinder

h = Height of the cylinder = 11 cm

A = Total surface area of the cylinder = $337\ \text{cm}^2$

Total surface area of a cylinder is given by

$A=2\pi r^2+2\pi rh\\\Rightarrow A=2\pi r(r+h)\\\Rightarrow \dfrac{A}{2\pi}=r^2+rh\\\Rightarrow r^2+rh-\dfrac{A}{2\pi}=0\\\Rightarrow r^2+11r-\dfrac{337}{2\pi}=0\\\Rightarrow r^2+11r-53.64=0\\\Rightarrow 100r^2+1100r-5364=0\\\Rightarrow r=\dfrac{-1100\pm \sqrt{1100^2-4\times 100\left(-5364\right)}}{2\times 100}\\\Rightarrow r=3.66,-14.65$

So, the radius of the circular top is 3.66 cm.
