The midpoint is C, (-0.5,0.5)
Find the middle between the x and y coordinates and that is the midpoint
Answer:
Step-by-step explanation:
2x⁴ + 4x³ - 30x² = 2x²*(x² + 2x - 15)
x² + 2x - 15
Sum = 2
Product = -15
Factors = 5 ; (-3)
x² + 2x - 15 = x² + 5x - 3x - 3 *5
= x(x + 5) - 3(x + 5)
= (x + 5)(x - 3)
2x⁴ + 4x³ - 30x² = (2x²) (x + 5)(x - 3)
Answer:
30 pounds
Step-by-step explanation:
Amount of tin in first alloy + amount of tin in second alloy = amount of tin in mixture
0.15 (20) + 0.10 x = 0.12 (20 + x)
3 + 0.10 x = 2.4 + 0.12 x
0.6 = 0.02 x
x = 30
Answer:
^G=98°
Step-by-step explanation:
So you know that angle x and angle g summed up together make 180°.
^F+^H+^G= 180°
<=> 53°+45°+^G=180°
<=> ^G= 180°-98°=82°
180°-82°=98°
