Answer:
unlimited
Step-by-step explanation:
When we have an equation with 2 variables, and they are of first degree, we can have unlimited number of solutions. The solutions are written as ordered pairs. For any value of x we can find y.
Answer:
y = -2x + 5
General Formulas and Concepts:
<u>Algebra I</u>
Slope-Intercept Form: y = mx + b
Step-by-step explanation:
<u>Step 1: Define given</u>
y-intercept <em>b</em> = 5
Slope <em>m</em> = -2
<u>Step 2: Write function</u>
y = -2x + 5
Answer:
The product of (4 +5x)(4-5x) is 16 - 25x².
Step-by-step explanation:
To find: Product of (4 +5x)(4-5x) using suitable identities.
Identity used : a² - b² = (a+b)(a-b)
Solution:
(4 +5x)(4-5x)
= (4)² - (5x)².........(using identity a² - b² = (a+b)(a-b))
(Here, a = 4 and b = 5x)
= 16 - 25x²
The given question can be solved without the use of the identity
a² - b² = (a+b)(a-b) as well.
Alternative Solution (without use of identity)-
(4 +5x)(4-5x)
(As (a+b)(c+d) = a(c+d)+b(c+d) )
= 4(4-5x) + 5x(4-5x)
= 16 - 20x + 20x - 25x²
= 16 - 25x²
Hence, the product of (4 +5x)(4-5x) is 16 - 25x².

Step-by-step explanation:
She would need 45 Ft. of material. I hope this helped ^^
