The graph of g(x) goes through the point (-4, 1) and is parallel to h(x) = 5x - 2 points

vesna_86 [32]

Answer:

$g(x)=5x+21$

Step-by-step explanation:

The slope of g(x) is 5 because the slope of h(x) is 5 and g is parallel to h.

In point-slope form:

$g(x)-1=5(x+4)$

Rearranging for slope intercept form:

$g(x)-1=5x+20\\g(x)=5x+21$

A 10 gallon aquarium is 3 inches higher than it is wide. Its length is 21 inches and its volume is 2730 inches. What are the hei

krok68 [10]

Answer: The height and width of the aquarium are 13 inches and 10 inches respectively .

Step-by-step explanation:

Given : The volume of aquarium = 2730 cubic inches

Length of aquarium = 21 inches

Let x be the width of the aquarium,

then Height = x+3

We consider the shape of aquarium as cuboid.

Volume of Cuboid = Length x width x Height

Put values in the above formula , we get

$2730=(21)(x)(x+3)\\\\\Rightarrow\ 130=x^2+3x\\\\\Rightarrow\ x^2+3x-130=0\\\\\Rightarrow\ x^2+13x-10x-130=0\\\\\Rightarrow\ x(x+13)-10(x+13)=0\\\\\Rightarrow\(x+13)(x-10)=0\\\\\Rightarrow\ x=-13\ or\ x=10$

So , the width of aquarium =x= 10 inches ( width cannot be negative)

So height = 10+3=13 inches.

Hence, the height and width of the aquarium are 13 inches and 10 inches respectively .
