Step-by-step explanation:
Answer:
D
Step-by-step explanation:
a² - b² ← is a difference of squares and is factored in general as
(a + b)(a - b)
42² - 38² ← is a difference of squares and factors as
42² - 38² = (42 + 38)(42 - 38) = 80(4) = 320 → D
sqrt(7) can be multiplied by 0 and sqrt 7 to become rational.
A and D
Answer:
m= - 2, b = 4
Step-by-step explanation:
structure of a linear equation
y = mx + c
m = gradient / slope
c = intercept
<em>convert</em><em> </em><em>the </em><em>given </em><em>equation</em><em> </em><em>according </em><em>to</em><em> </em><em>this</em><em> </em><em>structure</em><em> </em><em>of</em><em> </em><em>linear </em><em>equations</em><em> </em>
4x+2y = 8
2y = -4x + 8
y = -2x +4
<em>according</em><em> </em><em>to</em><em> </em><em>this </em><em>intercept</em><em> </em><em>is </em><em>4</em><em> </em><em>and </em><em>slope </em><em>is </em><em>-</em><em>2</em>
