Concerning the interrogate, the retort to such is identified as the following,,
Convert the Slope-Intercept Form to General Form:
Y = -2x - 9 ==> 2x + y = -9
Evaluate:
2x + y = -9
2x + 3y = -9
Multiply the X factors by each other, making one of the products opposite:
-2(2x + y) = -9 ==> -4x - 2y = 18
2(2x + 3y) = -9 ==> 4x + 6y = -18
Add the expressions:
-4x - 2y = 18
4x + 6y = -18
————————
4y = 0
Y = 0
Now, substitute the zero within one of the equations:
2x + 3y = -9
2x + 3(0) = -9
2x = -9
X = -4.5
Thus, (-4.5,0)
Square root of 12-1 = 3.32
5/2 = 2.5
2.25
1+(3.14/2) = 2.57
Greatest to least: Square root of 12-1, 1+3.14/2, 5/2, 2.25
Answer:
14
Step-by-step explanation:
24/16 = 21/x
(24/16) • 21 = 14
Answer:
7.)12x^2+18x
Step-by-step explanation:
Answer:
a) The equation of Z and C is Z =K C
b) K = 2
Step-by-step explanation:
<u><em>Explanation</em></u><em> </em>:-
<em>Given data Z is directly proportional to C</em>
<em> ⇒ Z ∝ C</em>
⇒ Z = K C
The equation of relating Z and C
<em> Z = K C</em>
Given Z = 20 and C =10
20 = K ( 10)
⇒<em> K = 2</em>
