Answer:

10/11

Step-by-step explanation:

The fractions already have like denominators so you just add the numerators as there is no need to find the LCM but just in case

ololo11 [35]

In ΔABC, D and E are the midpoints of AB and AC respectively. We know that the ratio of areas of two similar triangles is equal to the ratio of square of their corresponding sides. Hence, the ratio of the areas ΔADE and ΔABC is ar(ΔADE) : ar(ΔABC) = 1 : 4.

3. Write an equation of the direct variation that includes the point (6, -2).

lana66690 [7]

Answer:

$y=-\frac{1}{3}x$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation ( or direct variation) if it can be expressed in the form $k=\frac{y}{x}$ or $y=kx$

In a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

we have the point (6,-2)

Find the constant of proportionality k

$k=\frac{-2}{6}$

Simplify

$k=-\frac{1}{3}$

therefore

The equation of the direct variation is

$y=-\frac{1}{3}x$

(x-19)/2=(x-7)/1<br><br>step by step please

Maksim231197 [3]

Answer:

X=-5

Step-by-step explanation:

Since anything divided by one is still that number, then (x-7)/1 becomes x-7. So our equation now looks like:

(X-19)/2=(x-7).

Multiplying both sides by 2, we get

X-19=2x-14

Adding 19 to both sides:

X=2x+5

Subtract 2x from both sides:

-x=5

Multiplying both sides by -1, we get:

X=-5

The velocity of a particle can be modeled by the function v(t)=1/10 (3t-8)^3+2 graph it

Aloiza [94]

v (t) = 1/10 (3t-8) ^ 3 + 2
For this case, what you should keep in mind is that you can use any computational tool to graph this function.
You can use for example excel, or wolfram alpha.
Just keep in mind that:
Dependent variable: v (t)
Independent variable: t
Answer:
See attached image for the graphic.
