Answer:
A; infinitely many solutions
Step-by-step explanation:
first, let's simplify the first equation to make it simpler.
divide both sides by 5
y=3x-8
new system
y=3x-8
y=3x-8
as you can see, they are the same.
not mandatory but useful!⬇⬇⬇⬇
just to be more clear, let's substitute them. since they're both already in y=, we can make them both set to each other.
3x-8=3x-8
add 8 to both sides; subtract 3x from one side
0=0
the answer is A, Infinitely many solutions.

Answer:
Option A) Bethany is correct because consecutive odd integers will each have a difference of two
Step-by-step explanation:
The sum of 3 consecutive odd integers is 91. Let the first odd integer is x. The next odd integer will be obtained by adding 2 in x i.e. (x + 2). The third odd integer will be obtained by adding 2 in the second odd integer i.e. (x + 2) + 2 = x + 4
So, the 3 odd integers will be:
x , (x+2) and (x+4)
Their sum is given to be 91. So we can write:
x + (x+2) + (x+4) = 91
Hence, we can conclude that: Bethany is correct because consecutive odd integers will each have a difference of two.
Other options are not correct because consecutive odd integers always increase by 2. For example, the next odd integer after 1 is 3, which is obtained by adding two, similarly the next odd will be 5 and so on.
Answer: Jim is <span>15 years old
Jim = 15 years old,
</span><span>Dad is 4 times as old as his son Jim = = 15 x 4 = 60
In 10 years, Jim = 15 + 10 =25 years old
Dad = 60 + 10 = 70
</span><span>Dad's age will be 20 years more than twice Jim's age
</span><span>
Dad's age = 20 + 2(25) = 70
</span>
Answer:
2x3 +10x2 -2x -10
Step-by-step explanation:
x2 + x + 5x + 5
(x2 + 6x + 5 )(2x -2)
2x3 + 12x2 + 10x - 2x2 -12x - 10
2x3 +10x2 -2x -10
Answer:
I know this is late but here
Slope = -1/25, y-intercept = 15
I can’t really explain it though
