Step 1: Define Systems
y = -6x - 16
-2x + 4y = -2
Step 2: Solve for x
Substitution
Substitute in y: -2x + 4(-6x - 16) = -2Distribute 4: -2x - 24x - 64 = -2Combine like terms: -26x - 64 = -2[Addition Property of Equality] Add 64 on both sides: -26x = 62[Division Property of Equality] Divide -26 on both sides: x = -31/13Step 3: Solve for y
Define original equation: y = -6x - 16Substitute in x: y = -6(-31/13) - 16Multiply: y = 186/13 - 16Subtract: y = -22/13I need with this math problem please!

Solve using any method
6x+15y=9
4x+10y=8
Answer: Multiply each equation by the value that makes the coefficients of opposite.
(−2) ⋅ (3x−15y) = (−2) (9) (-2) ⋅ (3x-15y) = (-2) (9) (3) ⋅ (2x−10y) = (3) (6)
Simplify.
–6x+30y= − 18
6x − 30y = 18

Is the relation in the table below a function?
Answer:
No
Step-by-step explanation:
A relation is a function if every x-value has exactly one y-value.
Because the x-value 1 has two y-values (-3 and 3), the relation is not a function.
Plotting (1, -3) and (1, 3) will produce a vertical line that intersects the function at two points.
Therefore, the relation is not a function.

what are the first 5 terms of
n+ 3
Answer:
The sequence of first five terms
4 , 5, 6, 7, 8
Step-by-step explanation:
Step(i):-
Given [tex]n^{th}[/tex] of the sequence
aₙ = n + 3 ..(i)
put n =1
a₁ = 1 +3
a₁ = 4
The first term of the sequence = 4
Put n =2 in equation (i)
a₂ = 2+3
a₂ = 5
The second term of the sequence = 5
put n=3 in equation (i)
a₃ = 3+3 = 6
The third term of the sequence = 6
Put n=4 in equation (i)
a₄ = 4 +3
a₄ = 7
The fourth term of the sequence = 7
Put n = 5 in equation (i)
a₅ = 5+3
a₅ = 8
The fifth term of the sequence = 8
Step(ii):-
The sequence of first five terms

Function c is defined by the equation c(n) = 50 + 4n. It gives the monthly cost, in
dollars, of visiting a gym as a function of the number of visits, n. Find the value of
c(7).
Answer:
The value of function at n = 7 is 78.
Step-by-step explanation:
Given function is:
c(n) = 50 + 4n
Here,
c represents the cost monthly cost of gym
n represents the number of visits to the gym
We have to find the value of c(7).
We will put n = 7 in the function.
Thus,
c(7) = 50 + 4(7)
c(7) = 50 + 28
c(7) = 78
Hence,
The value of function at n = 7 is 78.
The value of c(7) in the function c(n) = 50 + 4n is = 78
The function is defined as follows:
c(n) = 50 + 4n
where
function c is defined by the equation above
n is the number of visit
The function gives the monthly cost in dollars.
Therefore,
The value of c(7) can be found as follows:
c(7) = 50 + 4n
c(7) = 50 + 4(7)
c(7) = 50 + 28
c(7) = 78

The scale of a map is 1:4 000 000. Hint: 1:4 000 000 means that 1cm on the map = 4 000 000 on the ground. The distance between Leeds and London on this map is 8.125cm. Calculate the actual distance between Leeds and London. Give your answer in kilometres.
Answer:
325 km
Step-by-step explanation:
Given the scale :
1 : 4 ,000, 000
1cm measure in map = 4000000 on the ground
From the map :
Distance between Leeds and London = 8.125 cm
The actual distance on ground can be calculated thus :
1cm = 4,000,000
8.125cm = x
Cross multiply
x = 32500000 cm
Converting to kilometers :
1 km = 100,000 cm
x = 32500000
Cross multiply
100,000x = 32500000
x = 32500000 / 100000
x = 325
Hence, actual distance between Leeds and London is 325 km

6z-7>8z+2? = z < -9/2
Step-by-step explanation:
6*z-7-(8*z+2)>0
-2z - 9 = -1 • (2z + 9
Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
2z+9 < 0
Divide both sides by 2
z+(9/2) < 0
Subtract 9/2 from both sides
z < -9/2
Answer: z < -9/2
Answer:
z is (less than) -9/2 is the correct answer use the symbol for less than.
