Y = 3/2x + 6....slope here is 3/2.A parallel line will have the same slope.

y = mx + b
slope(m) = 3/2
(2,-1)...x = 2 and y = -1
now we sub and find b, the y int
-1 = 3/2(2) + b
-1 = 3 + b
-1 - 3 = b
-4 = b
so ur parallel line is : y = 3/2x - 4

u sure u wrote this question correctly ??

The shower block on the campsite has an area of 144 m2 The length of the shower block is 24 m.What is the width?

g100num [7]

Since the shower block is in the form of a rectangle. The shower block has an area of 144 $m^{2}$ . It has a length of 24m. We need to calculate the width of the shower block.

Area of rectangular shower block = length $\times$ width

144 $m^{2}$ = 24 m $\times$ width

width = $= \frac{144m^{2}}{24m}$

width = 6m

So, the width of the shower block is 6 meters.

A rectangular Corn Hole area at the Recreation Center has a width of 5 feet and a length of 10 feet. If

inysia [295]

Answer:

2 feet

Step-by-step explanation:

Let

x ----> the uniform amount added to each side

we know that

The algebraic expression that represent this situation is

$(5+x)(10+x)=84$

solve for x

Apply distributive property

$50+ 5x+10x+x^2=84\\x^2+15x-34=0$

solve the quadratic c equation

The formula to solve a quadratic equation of the form

$ax^{2} +bx+c=0$

is equal to

$x=\frac{-b\pm\sqrt{b^{2}-4ac}} {2a}$

in this problem we have

$x^2+15x-34=0$

$a=1\\b=15\\c=-34$

substitute in the formula

$x=\frac{-15\pm\sqrt{15^{2}-4(1)(-34)}} {2(1)}$

$x=\frac{-15\pm\sqrt{361}} {2}$

$x=\frac{-15\pm19} {2}$

$x=\frac{-15\pm19} {2}=2$

$x=\frac{-15\pm19} {2}=-17$

therefore

The solution is x=2 ft

At a camp in Green Bay, Wisconsin, 7 9 of the participants were from Wisconsin. Of that group, 6 15 were 12 years old.

Karolina [17]

Complete question :

At camp in Green Bay, Wisconsin, 7/9 of the participants were from Wisconsin. Of that group 3/5 were 12 years old. What fraction of the group was from Wisconsin and 12 years old?

Answer:

7/ 15

Step-by-step explanation:

Fraction from Wisconsin = 7/9

Fraction who are 12 years old = 3/5

Fraction who are from Wisconsin and 12 years old

(Fraction from Wisconsin * Fraction who are 12 years old)

(7 / 9 * 3/ 5)

= (7 * 3) / (9 * 5)

= 21 / 45

= 7 / 15

Why did the inequality sign flip?

kumpel [21]

Answer:

We multiplied by a negative number (-8)

We divided by a negative number (-8)

Step-by-step explanation:

Multiplying or dividing both sides of an equation by a negative number changes the inequality of the equation, because it changes the sign of each side of the equation
