Answer:
y-intercept: 1
slope: -2
Step-by-step explanation:
The actual building is 220 foot high.
We can use the proportion:
H : W = 25 in : 10 in
220 : x = 25 : 10
220 * 10 = 25 x
2,200 = 25 x
x = 2,200 : 25
x = 88 ft
Answer: The actual building is 88 ft wide.
Answer:
m + n = 26 and n = 2m + 5
m = 7, n = 19
Step-by-step explanation:
Because we know that the sum of m and n is 26, we get the first equation. For the second equation, we are told that n is five more than twice m. So we multiple m by 2 and then add 5 to that to get what n is. This is our second equation.
We plug the second equation in for n in the first equation to get
m + (2m + 5) = 26
3m + 5 = 26
3m = 21
m = 7
And then for n, we solve the first equation to get
7 + n = 26
n = 19
Answer:
A. Solution to but not to
Step-by-step explanation:
Given
Required
Is a solution?
implies that:
To check if it is a solution or not, we simply substitute 0 for x and for y in the given inequalities
becomes
This solution is true
becomes
This solution is not true because 0 is greater than 1.
Hence, option (A) is correct
No if you use the equation that it gives then no
