tangare [24]
25 days

First, start with an equation

100+8x= kittens weight

(X representing the days)

Since you’re trying to figure out the number of days it takes the kitten to triple it’s weigh you multiply it’s initial weight by 3 (100•3)

Then, you output 300 into the equation and solve

Find the gradient of the line segment between the points (-4,1) and (2,4). Give your answer in its simplest form.
andrew-mc [135]

Answer:

<h2>\frac{1}{2}</h2>

Solution,

Let the points be A and B

A(-4 , 1)------>( X1, y1)

B(2,4)---------->( x2, y2)

Now,

Gradient:

\frac{y2 - y1}{x2 - x1}

\frac{4 - 1}{2 - ( - 4)}

\frac{3}{2 + 4}

\frac{3}{6}

\frac{1}{2}

Hope this helps...

Good luck on your assignment...

translate this into an expression: the quotient of a number, x, and 8, could you please explain it to me?​
Xelga [282]

Answer:

x/8

Step-by-step explanation:

First, we are given "the quotient of...". This means that we are dividing something/something else. If two numbers are given in the phrase "something and something else", the first number given will be the something, and the second number will be the something else.

The first number listed is x. Therefore, we have

x/something else.

Next, we are given "and 8", so we have x/8 as our expression

The sum of three numbers is 180. If the first number is (2 x minus 11), and the second is (x minus 4) which expression represent
kirill115 [55]

Answer:

The third number is 195-3x

Step-by-step explanation:

Given:

sum of three numbers, a, b, c is 180.

a=2x-11

b=x-4

c= ?

Solution:

a+b+c = 180

2x-11 + x-4 + c = 180

c = 180 - (2x-11) - (x-4)

= 180 -2x+11 - x+4

= 180 + 11 + 4 -2x -x

= 195 -3x

In order to successfully perform a trick, a flying trapeze artist must swing along a parabolic path that is equidistant from the
Aliun [14]
<span>Given that the directrix of the parabola is at y = -8 and the focus is at point (8, 16), this means that the parabola opens upwards and the x part of the equation of the parabola is squared. The x-value of the vertex of a parabola is the same as the x-value of the focus while the y-value of the vertex is half the sum of y-values of the focus and the directrix. Therefore, the vertex of the given parabola is (8, (16 - 8)/2) = (8, 8/2) = (8, 4).</span>
