Answer:
D. -3 and 3
Step-by-step explanation:
We are given an output of 2. This means this is the value we need an input for. We need to find a number(s) that lie on the x axis and when we move up, you get an output of 2.
Option A:
If we are given an input of -2, we start at (-2, 0) and move up until we reach a point on the line. We end up lying on the point (-2, 3). Thus, the output for having an input of -2 is 3 which proves that this answer is incorrect.
Option B:
As stated above -2 has an output of 3 which is wrong. Since we know this, we can eliminate this as an option.
Option C:
If we are given an input of -3, we start at (-3, 0) and move up until we reach a point on the line. We end up lying on the point (-3, 2). Thus, the output for having an input of -2 is 2 which proves that this answer is correct.
Option D:
We know that -3 is a possible input so we just need to check 3 as an input.
If we are given an input of 3, we start at (3, 0) and move up until we reach a point on the line. We end up lying on the point (3, 2). Thus, the output for having an input of 3 is 2 which proves that this answer is also correct.
Since we know that -3 and 3 are possible inputs for an output of 2 on the graph, we need to include them both in our answer. Thus, the answer is D.
Best of Luck!
Answer:
1/2x + 5
Step-by-step explanation:
The y intercept is 5 & the slope is already given!
An identity, in mathematics, is a relation between A and B that would result to an equality of the two. It should be expressed as A = B wherein both values has some variables that would produce the same value no matter what will be the values used for the two functions. We are given the equation as follows:
a(2x+3)=9x+15+x
To determine the value of a that would make this equation an identity, we assume a value for x. We can assume a value of 1. We do as follows:
a(2 + 3) = 9 + 15 +1
5a = 25
a = 5
Therefore, the value of a would be 5.
Substitute value of y from equation (1) in equation (2),
5x-4(5-3x) = -3
5x-20+12x = -3
17x=17
x = 1
Substitute it in equation (1),
y = 5-3(1)
y = 5-3 = 2
So, the values (x,y) = (1,2)
Answer:
1,200
Step-by-step explanation:
To do this problem you do ten to the 2nd power which is 100 then you multiply 100 by 1.2 which is 120, which is then multiplied by 10 to get 1,200
