Step-by-step explanation:

Tanisha, Elicia, and Ajua are cousins. Tanisha is twice as old as Ajua, and Elicia is two years older than Tanisha. The sum of all their ages is 37. Use variable expressions and calculate the age of each girl

Let us represent:

The age of :

Tanisha = a

Elicia = b

Ajua = c

Tanisha, Elicia, and Ajua are cousins. Tanisha is twice as old as Ajua

a = 2c

c = 2/a

Elicia is two years older than Tanisha.l

b = a + 2

The sum of all their ages is 37.

a + b + c = 37

We substitute

a + a + 2 + 2/a = 37

2a + 2 + 2/a = 37

Use variable expressions and calculate the age of each girl

Answer:4/3 i think

Step-by-step explanation:

Answer:

Point-slope form:

[tex]\displaystyle y-3=-\frac{1}{3}(x-3)[/tex]

Slope-intercept form:

[tex]\displaystyle y=-\frac{1}{3}x+4[/tex]

Step-by-step explanation:

We want the equation in point-slope form and slope-intercept form that passes through the points (-3, 5) and (3, 3).

First, we will find the slope between the two points. By the slope formula:

[tex]\displaystyle m=\frac{5-3}{-3-3}=\frac{2}{-6}=-\frac{1}{3}[/tex]

Point-slope form is given by:

[tex]\displaystyle y-y_1=m(x-x_1)[/tex]

We can choose either point. I'm going to let (3, 3) be (x₁, y₁). The slope m is -1/3. Therefore:

[tex]\displaystyle y-3=-\frac{1}{3}(x-3)[/tex]

Is the point-slope form*.

To find the slope-intercept form, we simply need to isolate y. Distribute:

[tex]\displaystyle y-3=-\frac{1}{3}x+1[/tex]

Adding 3 to both sides yields:

[tex]\displaystyle y=-\frac{1}{3}x+4[/tex]

This is slope-intercept form.

*If you use the other point, the point-slope form will be:

[tex]\displaystyle y-5=-\frac{1}{3}(x+3)[/tex]

Answer:

The last one is a function.

Step-by-step explanation:

When the x value corresponds to different y values e.g. (1,2)(1,1), then it automatically isn't a function.  Another simple way to find out if something is a function is to graph and try the vertical line test.  If the line passes through multiple points on it's way down, then it's not a function.

Answer:

18 meters by 14 meters

Step-by-step explanation:

Area of rectangle is base times height (AKA length times width or however you wish to call the dimensions).

This question is a system of equations question. We can make two equations. We know that every rectangle must have 2 "lengths" and 2 "widths" (4 sides in a rectangle). Since Maria only has 64 meters of fencing, we get the equation:

2L+2W = 64

Now we know the area enclosed must be 252 so we have:

L* W = 252

Rewriting the second equation we get: [tex]W=\frac{252}{L}[/tex]

Plug this into first equation to get: [tex]2L+2\left(\frac{252}{L}\right)=64[/tex]

[tex]2L+\frac{504}{L}=64[/tex]

[tex]2L^2+504=64L[/tex] (multiply everything by L)

Solving the quadratic tells us L can be 18 or 14. Let's consider if L is 18 first by plugging 18 back into the second equation to get 18 * W = 252 which gives us W = 14. If we do the same for when L = 14, we get that W = 18.

Now you might wonder why we have 2 possible combinations, that's because in reality, it doesn't matter which one we label as length (L) or width (W).

Given:

Point D is the centroid of Triangle ABC and DE = 9.

To find:

The measures of CD and CE.

Solution:

We know that, centroid is the intersection of medians and it divides each median in 2:1.

In triangle ABC, CE is a meaning and centroid D divided CE in 2:1. So,

Let the measures of CD and DE are 2x and x respectively.

DE = 9                (Given)

[tex]x=9[/tex]

Now,

[tex]CD=2x[/tex]

[tex]CD=2(9)[/tex]

[tex]CD=18[/tex]

And,

[tex]CE=CD+DE[/tex]

[tex]CE=18+9[/tex]

[tex]CE=27[/tex]

Therefore, the measure of CD is 18 units and the measure of CE is 27 units.

The measure of CD and CE are 18 and 27 respectively

From the given diagram, the following are true:

Given that DE = 9

CD = 2(9)

CD = 18

Similarly;

CE = CD + DE

CE = 18 + 9

CE = 27

Hence the measure of CD and CE are 18 and 27 respectively

The counterexample shows that Heng's definition does not fully define a reflection is Heny fully defined a reflection. Option D

Consider the counterexample in which point M is above line r and the line itself is a vertical line.

Assume M is located at (0, 2) and that line r is the x = 1 line. Heng's definition states that point M', which has a midpoint L that is on line r, should reflect point M across line r.

However, point M' at (-1, 2) would be the reflection of point M across line r, which does not meet the requirement that the midpoint L lies on line r. Therefore, in this counterexample, Heng's definition does not adequately characterize a reflection.

Answer:

[tex]\left(x-5\right)^6\left(x+3\right)^3\left(11x+1\right)[/tex]

and

[tex]x=5,\:x=-3,\:x=-\frac{1}{11}[/tex]

Step-by-step explanation:

This problem is slightly more difficult.

We start off with the product rule. If y = v*u then in the case:

[tex]u=\left(x+3\right)^4,\:v=\left(x-5\right)^7[/tex]

[tex]=> \frac{d}{dx}\left(\left(x+3\right)^4\right)\left(x-5\right)^7+\frac{d}{dx}\left(\left(x-5\right)^7\right)\left(x+3\right)^4[/tex]

Now we apply the chain rule:

[tex]\frac{d}{dx}\left(\left(x+3\right)^4\right) = 4\left(x+3\right)^3\frac{d}{dx}\left(x+3\right)\\= 4\left(x+3\right)^3\cdot \:1\\= 4\left(x+3\right)^3[/tex]

We can apply the chain rule again for this second bit:

[tex]\frac{d}{dx}\left(\left(x-5\right)^7\right) = 7\left(x-5\right)^6\frac{d}{dx}\left(x-5\right)\\= 7\left(x-5\right)^6\cdot \:1\\= 7\left(x-5\right)^6[/tex]

So now we are left with this long equation:

[tex]4\left(x+3\right)^3\left(x-5\right)^7+7\left(x-5\right)^6\left(x+3\right)^4[/tex]

Which we can actually factor:

[tex]4\left(x+3\right)^3\left(x-5\right)^7+7\left(x-5\right)^6\left(x+3\right)^4 = \left(x-5\right)^6\left(x+3\right)^3\left(4\left(x-5\right)+7\left(x+3\right)\right) \\= \left(x-5\right)^6\left(x+3\right)^3\left(11x+1\right)[/tex]

...And for the second bit, if we equate to 0, we can apply the Zero Product Property to get all the x values:

[tex]\left(x-5\right)^6\left(x+3\right)^3\left(11x+1\right)=0,\\x=5,\:x=-3,\:x=-\frac{1}{11}[/tex]
