We know, a² - 2ab + b² = (a - b)²
Here, a² = 16b²
So, a = 4b

b² = 25
b = 5

Factors would be: (4b - 5)²

Hope this helps!

The points ( - 6,5) and ( - 7,q) fall on a line with a slope of 10. What is the value of q?
Usimov [2.4K]
If you go on my profile you will see a similar problem that I already answered today.

Lets start by using a formula (don't remember the name) 

(y-y1)=M(x-x1)

M is slope and y is first y value and y1 is second y value same applies to X.

Substitute in the values.

(5-q) = 10(-6-(-7))

5-q = 10*(1)

5-q = 10

-q = 5

q = -5

Check:

Substitute in the value of "q" and use the formula to find slope:

(y1-y)/(x1-x)

Substitute 

(-5-5)/(-7-(-6))
-10/-1
10

Your Answer: 
The value of "q" is -5

Solve for −4.2y+2.1>−2.52
Alchen [17]

Answer:

y < 1.1

Step-by-step explanation:

<u>Step 1:  Subtract 2.1 from both sides </u>

-4.2y + 2.1 - 2.1 > -2.52 - 2.1

<em>-4.2y > -4.62</em>

<em />

<u>Step 2:  Divide both sides by -4.2</u>

-4.2y / -4.2 > -4.62 / -4.2

<u><em>Since you divided by a negative, that flips the sign.</em></u>

<em>y < 1.1 </em>

Answer:  y < 1.1
