Hey there! :)
Answer:
y = 11.
Step-by-step explanation:
Set both of the equations equal:
5x - 9 = x² - 3x + 7
Rearrange the equation:
0 = x² - 3x - 5x + 9 + 7
Combine like terms:
0 = x² - 8x + 16
Factor:
0 = (x -4)²
Solve for x:
0 = x - 4
x = 4.
Plug this into an equation to solve for 'y':
y = 5(4) - 9
y = 20 - 9
y = 11.
Answer:
x = 4
y = 11
Step-by-step explanation:
Set your formula as follow:
2x+3=3x-1 -> 2x+3-3x=-1 -> -x+3 = -1 -> -x=-4 -> x=4
now substitute x for 4 in the following
y-2=2(4)+1 -> y-2=8+1 ->y-2 = 9y -> y=11
Answer:
a: 12
B: 5
c: 15
Step-by-step explanation: because you have to multiply and divide but i might have the wrong answerr :((((
Answer:
+ 3x³ - 16x² + 27x - 18
Step-by-step explanation:
Each term in the second factor is multiplied by each term in the first factor, that is
x²(4x² - 5x + 6) + 2x(4x² - 5x + 6) - 3(4x² - 5x + 6)
Distribute all 3 parenthesis
= 4 - 5x³ + 6x² + 8x³ - 10x² + 12x - 12x² + 15x - 18
Collecting like terms
= 4 + 3x³ - 16x² + 27x - 18

Answer:
B. 66 m
Step-by-step explanation:
Map and ground distances are proportional:
ground/map = ground/(12 cm) = (11 m)/(2 cm)
ground = (12 cm)(11 m/(2 cm)) = 66 m
The distance from A to B is 66 m.
