Answer:
Step-by-step explanation:
Given the expression of the area model as:
10x^2-8x-24
Factorize:
(10x^2-20x)+(12x-24)
factor out the GCF
10x(x-2)+ 12(x-2)
(10x+12)(x-2)
<h3>Hence the two terms that forms the area of the model above are 10x+12 and x-2</h3>
Answer:
(1) x=
−1
/2
y+
5
/2
(2)
x=
−1
/2
y−2
Step-by-step explanation:
<u>(1)</u> 2x+y=5
Step 1: Add -y to both sides.
2x+y+−y=5+−y
2x=−y+5
Step 2: Divide both sides by 2.
2x
/2
=
(−y+5)/2
x=
−1
/2
y+
5
/2
<u>(2) </u>Step 1: Flip the equation.
−2x−4=y
Step 2: Add 4 to both sides.
−2x−4+4=y+4
−2x=y+4
Step 3: Divide both sides by -2.
−2x
/−2
=
(y+4)

Answer:
y = -1/2c - 8
Step-by-step explanation:
2c - y = 6
2c -6 = y
Slope: 2. Slope of the perpendicular line: -1/2
Point (-4,-6)
y-intercept = -6 - (-1/2)(-4)
b = -6 -2 = -8
The circumference will be 18.683
Answer:
(y - 3)(y - 5)
Step-by-step explanation:
Consider the product of the factors of the constant term which sum to give the coefficient of the y- term
product = + 15, sum = - 8
The factors are - 3 and - 5
y² - 8y + 15 = (y - 3)(y - 5)
