Answer: (1,-5)
Step-by-step explanation:
We have
y=-7x+2
y=9x-14?
So
Y=-7X+2
Substituying in y=9x-14
We have
-7x+2=9x-14
16x=14+2
16x=16
x=16/16=1
x=1
so we have:
y=9(1)-14
y=-5
finally the answer is (1,-5)
Answer:
Both A and B
Step-by-step explanation:
For functions you are just trying to make sure all the x's are different.
So let's look at A: The x's there are all different so it is a function
Now let's look at B: The x's there are all different so it is a function.
Both A and B
First one is arithmetic sequence in disguise
an=a1+d(n-1)
a1=first term
d=common differce
n=which term
so
first erm is 4
common difference is 9-4=5
an=4+5(n-1)
when n=10
4+5(10-1)
4+5(9)
4+45
49
B
3.5, to 6.5, 9.5
aritmetic, increase by 3, first term is 3.5
an=3.5+3(n-1)
10th term
3.5+3(10-1)
3.5+3(9)
3.5+27
30.5
A is49
B is 30.5
A is answer
an=a1+d(n-1)
115+(-8)(14-1)
115-8(13)
115-104
11
answer is B
an=a1+d(n-1)
45+(-3)(10-1)
45-3(9)
45-27
18
C
Step-by-step explanation:
Can't see anything
Please be more specific
Answer:
Step-by-step explanation:
a.
y=4x-10
now you can put any real value of x,you get corresponding value of y.
b.
