Answer:
option B
2
Step-by-step explanation:
Given in the question
DO,h(7, 9) → (14, 18)
Formula to use
<h3>√(x1-x2)²+(y1-y2)²</h3>
distance formula = √((7-0)²+(9-0)²) = √(7²+9²) = √130
distance formula = √((14-0)²+(18-0)²) = √(14²+18²) = 2√130
Scale factor
√130 = 2√130
d = 2d
Answer:
-1
Step-by-step explanation:
-2/3 - 1/3
Since the denominators are the same, we can combine the numerators
-3/3
Simplify
-1
60.8 is
190% of 32
Divide 60.8 over 32:
Convert the decimal into a percentage by dividing it over 100:
A) x * y = 12
B) x + y = -7
A) x = 12 / y
Substitute this into B
B) 12/y + y = -7
multiplying both sides by "y"
12 + y^2 = -7y
y^2 + 7y + 12 = 0
y = -4
and from equation B we calculate x as -3
