Answer:
Price = 20, Amount = 14
Step-by-step explanation:
A = Amount of Mangoes
P = Price for 1 Mango
P = A + 6
280 = P * A
insert A+6 for P
280 = (A+6) * A
280 = 6A + A²
280=1*a^2+6*a | Vertausche beide Seiten der Gleichung.
1*a^2+6*a=280 | quadratische Ergänzung: ergänze auf beiden Seiten (3)^2
1*a^2+6*a+(3)^2=3^2+280 | Rechne 3 hoch 2 aus.
1*a^2+6*a+(3)^2=9+280 | addiere 9 und 280
1*a^2+6*a+(3)^2=9+280 | Fasse die rechte Seite mit Hilfe der binomischen Formel zusammen.
1*(1*a+(3))^2=289 | Auf beiden Seiten Quadratwurzel ziehen.
1*a+(3)=+-*289^0.5
1*a_1+(3)=289^0.5
1*a_1+3=289^0.5 | Ziehe die Wurzel aus 289
1*a_1+3=17 | -3
1*a_1=14
Answer:
yes because angle 1 and 5 are congruent
Answer: x=18
im assuming that this is a right angle
so if it is then that means the total of the angle should be 90 degrees. so 2x+3x should be equal to 90. Just combine like terms to get that 5x=90 and then isolate the variable (divide by 5 on both sides) so x ends up equaling 18.
so x=18
Answer:
D. √((2 +4)² +(5 -8)²)
Step-by-step explanation:
The distance is found using the formula ...
d = √((x1 -x2)² +(y1 -y2)²)
Selection D has this formula properly filled in with the values ...
(x1, y1) = (2, 5)
(x2, y2) = (-4, 8)
Answer:
m=-3/7
Step-by-step explanation:
(-4,2), (-3,5)
x1 y1 x2 y2
m=<u>y2-y1</u>
x2-x1
m=<u>5-2</u>
-3-4
m=<u>3</u>
-7
m=-3/7
