Answer:
y = 
x - 11
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (2, - 4) and (x₂, y₂ ) = (6, 10)
m = 
= 
= , thus
y = x + c ← is the partial equation
To find c substitute either of the 2 points into the partial equation
Using (2, - 4) , then
- 4 = 7 + c ⇒ c = - 4 - 7 = - 11
y = x - 11 ← equation of line
By working backwards,
<span>you get 76 as your answer because you have to remove the rightmost digit, right? so the three-digit number is </span>
<span>76x </span>
<span>(x stands for the rightmost digit, because we don't know what the rightmost digit is) </span>
<span>we are told we have to add six to the three digit number to get 76x, so we have to subtract 6 from 76x: </span>
<span>76x - 6 = ??? </span>
<span>since we assume that the original two-digit number is NOT 76, and any number from 760 to 765 inclusive minus 6 is logically in the 750-range, we can conclude that the original two-digit number is 75. </span>
Answer:
B
Step-by-step explanation:
because 10 and 11 are not equal, therefore, when you add 10 then subtract 11, you will not end up with your original number
Okay, so, for Problem number 1, we see that 30:36 and then we have 5:? Well, to get the five, we divided by 6. So that means we have to do the same thing to the 36 to make the ratios equivalent (equal to) each other. Final Answer: 6
For number 2, it’s a little different. We have what our ratio is equal to, but not the entire starting ratio. However, if we look we see that we have a 6 in the first part and a 3 in the second. That must mean that we divided the 6 by 2 to get the 3. 8 divided by 2 is equal to 4, so our final answer would be 8.
In number 3, we multiplied by 2, because 2x2=4. So we would multiply the 1 by 2 to get that blank space. Final Answer: 2
For number 4, we multiplied by 5. Now we just have to multiply 2 by 5 to get the answer, which is 10.
Lastly on number 5, we are multiplying by 2. To find the blank space, we have to do the “invers operation” which is the opposite operation. So instead of multiplication, we’ll use division. We are going to divide 18 by 2 to get the blank spot. Final answer: 9
The number 80% is greater than 7/9.
