Answer:

yes

Step-by-step explanation:

Hey There!

We can find the answer by using proportions of the other sides

What i mean by this is if ADs proportion to AE is the same as BDs proportion to EC then DE is proportional to BC

6/4=1.5

9/6=1.5

Therefore DE is proportional (or similar) to BC

Help pls need help show your solution and then graph​
Stella [2.4K]

Answer:

Step-by-step explanation:

We can use the quadratic formula or factor, This looks hard to factor so we should use the quadratic formula.

ax^2 + bx + c

so

a=4

b=-9

c=2

you can try it by hand or use this:

https://www.calculatorsoup.com/calculators/algebra/quadratic-formula-calculator.php

you get x=2 and x=0.25 these are the x intercepts (where Y is zero and where the graph crosses the x axis)

so mark x=2 and x=0.25 with a dot on a number line and you can draw a straight line between them since that is the part of the graph that is below the x axis (because the equation has <0) it is a positive parabola because the "a" value is positive and the presence of a "b" value means part of the graph will be below the x axis

A scientist was in a submarine below sea level, studying ocean life. Over the next ten minutes, she dropped 24.9 feet. How many
Harrizon [31]

The Depth of the Scientist before dropping is;  42.2 ft

<h3>How to calculate sea level elevation?</h3>

It is pertinent to note that sea level is usually considered zero level. Thus, one is either above the sea level (positive sign) or below the sea level.

Now, we are told that the scientist was already below the sea level before she dropped 24.9 ft.

Now, if after dropping 24.9 ft, she is now 66.7 ft below sea level, then it means that the depth she was at before dropping 24.9 ft is;

Depth before dropping 24.9 ft = 66.7 - 24.9

Depth before dropping = 42.2 ft

How do i find the equation of the line?
Cerrena [4.2K]

Answer:

10x + 7y = 2

Step-by-step explanation:

Slope = (6 + 4)/(-4 - 3) = -10/7

Equation:

y + 4 = -10/7(x - 3)

7(y + 4) = - 10(x - 3)

7y + 28 = -10x + 30

10x + 7y = 30 - 28

10x + 7y = 2
