Answer:

<em>Solution; u = 2.5</em>

Step-by-step explanation:

We can neglect the information provided to us, besides that of the equation 9(u – 2) + 1.5u = 8.25, as we are only to find the value of u, any other information is not of need;

9(u – 2) + 1.5u = 8.25 ⇒ apply the distributive property on the expression ( u - 2 ), distributing the 9 to the elements inside,

9u - 18 + 1.5u = 8.25 ⇒ add like elements,

10.5u = 26.25, solve for u,

<em>Solution; u = 2.5</em>

vfiekz [6]

Answer:

y intercept

Step-by-step explanation:

At first I didn't think there was enough information, but there is. In general terms, for any polynomial which is also a function, making x = 0 gives the point where (0,b) = the y intercept.

For example

using f(x) = x^2 + 4x + 6 when x = 0 the result left is f(0) = 6 so the y intercept is (0,6)

If you have x^2 + 6x the y intercept is (0,0)

lidiya [134]

The number of adults waiting to see the new superhero movie is 62.

<h3>How many adults are waiting in line?</h3>

Ratio expresses the relationship between two or more numbers. Ratio is used to compare two or more numbers. It shows the number of times that one value is contained in another value.

Looking at the ratio given in this question, we know that there are 1 1/2 (3 /2) more children than adults on the line to watch the new superhero movie.

Number of adults waiting to see the movie = (ratio that represents adults / sum of ratio) x total number of people wafting in line

Sum of ratios = 2 + 3 = 5

(2/5) x 155 = 62 people

When a figure is translated, reflected, or rotated, what's the same about the original igure and its image? What's different?
Liula [17]

Answer:

The image of a translation, reflection, or rotation is congruent to the original figure, and the image of a dilation is similar to the original figure. Two figures are similar when one can be obtained from the other by a sequence of translations, reflections, rotations, and dilations.
