0.75
To get his you must simply divide 75/100. This gives you .75
Answer:
No real solutions.
Step-by-step explanation:
I'm going to subtract the second expression for y and plug it into the first equation.
So solving x=y+8 for y by subtracting 8 on both sides gives us y=x-8.
I'm going to insert this for the first y like so:
Now I'm going to move everything to one side.
I'm going to subtract x on both sides and add 8 on both sides.
Simplifying:
Now our job since the coefficient of x^2 is 1 is to find two numbers that multiply to be 4 and at the same time add up to be -3. I can't think of any such numbers.
Let's check the discriminant.
Compare 
to 
.
So 
.
The discriminant is 
.
So plugging in our numbers we get 
.
Time to simplify:
So since the discriminant is negative, then the solutions will not be real.
Answer:
y + 1 - 5(x - 2)
Step-by-step explanation:
Borrow (2, -1): Substitute 2 for x and -1 for y, and -5 for m in y = mx + b:
-1 = -5(2) + b. Then b = 9, and the desired equation in point-slope form is:
y - (-1) = -5(x - 2), or
y + 1 - 5(x - 2)
Answer:
Step-by-step explanation:
You really don't have enough information to solve this with one answer. You want a value for y and there is no what to limit it to just 1 set of values. For example if x = 23 then
x = y + y - 3
x = 2y - 3
23 = 2y - 3 Add three to both sides
23+3 = 2y Combine
26 = 2y Divide by 2
26/2 = 2y/2 Do the division
13 = y
The smaller number is 13 - 3 = 10
Their sum is 13 + 10=23 But that answer is not unique.
====================
Suppose x = 13
13 = 2y - 3 Add 3
13 + 3 = 2y
16 = 2y
y =8
The larger number = 8
The smaller number = 5
=======================
The best I can do is give you the equation which is
x = 2y - 3
The like terms in this expression are 6x^4 & 5x^4.
