solve the simultaneous equation:
y=x^2+3
y-2x=18
Answer:
(- 3, 12 ) and (5, 28 )
Step-by-step explanation:
Given the 2 equations
y = x² + 3 → (1)
y - 2x = 18 → (2)
Substitute y = x² + 3 into (2)
x² + 3 - 2x = 18 ( subtract 18 from both sides )
x² - 2x - 15 = 0 ← in standard form
(x + 3)(x - 5) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x - 5 = 0 ⇒ x = 5
Substitute these values into (1) for corresponding values of y
x = - 3 : y = (- 3)² + 3 = 9 + 3 = 12 ⇒ (- 3, 12 )
x = 5 : y = 5² + 3 = 25 + 3 = 28 ⇒ (5, 28 )

A woman takes 3000 on a vacation and spends 150 a day which expression gives the amount she has in dollars after n days
Thomas has 3 boxes, each with 8 balls.
He wants to place the balls evenly into 4 boxes.
How many balls will be in each of the 4 boxes?
Answer: 6 balls will be in each of the 4 boxes.
Step-by-step explanation:
Multiply 3x8 to find out how many balls there are total.
3x8=24
Then to split them evenly, you divide by 4 (the amount of boxes they are split into)
24/4= 6

Please help I don’t know
Answer:
k = 16/3
Step-by-step explanation:
Start by calculating the difference on the left side.
1/4k - 4 + 5/4k = 3/8k + 2
Multiply both sides of the equation by 8
2k - 32 + 10k = 3k + 16
Calculate sum on left side
12k - 32 = 3k + 16
Subtract 3k and add 32 to both sides
9k = 48
Divide both sides by 9
k = 48/9 = 16/3

please help i don’t understand
Step-by-step explanation:
a) given slope=m1=a/3
slope of parallel line=m2=5/6
parallel lines have equal slopes:
m1=m2
a/3=5/6
a=5/6×3
a=5/2
b) m1=a/3
m2=-2/9
lines are parallel:
m1=m2
a/3=-2/9
a=-2/9×3
a=-2/3
c)m1=a/3
m2=6
Slopes are perpendicular:
m1×m2=-1
a/3×6=-1
a×2=-1
a=-1/2
d)m1=a/3
m2=6/7
lines are perpendicular:
m1×m2=-1
a/3×6/7=-1
a×2/7=-1
a=-7/2

Answer:
A.( 3m+28)/4
Step-by-step explanation:
So basically since it is addition we just add 9 to -2 to get 7. So then the equation becomes (3m/4)+7. Then we will multiply 7 by 4 to get common denominator so it will be (3m+(7*4))/4 which is (3m+28)/4.
Given the equation.
f(x)=x^3+3x
Solve for x.
Answer:
x=0
Step-by-step explanation:
I think solve for x is just finding the zero or root of the equation?
