To solve this, you already have the y value of the coordinate, which is 3, and the x value is represented by a. Plug the values into your graph equation so that it looks like this: 3=2a-5
Then, add 5 to both sides to isolate 2a:
8=2a
Finally, divide both sides by 2 to get that a=4
Hope this helps!
Answer:
6, 8, 10
Step-by-step explanation:
First, solve the inequality
To do this, we need to get n by itself
n +5 > 10
5 is being added to n. To undo this, subtract 5 from both sides, since subtraction is the opposite of addition. This will eliminate the 5 on the left side, and leave n by itself.
n+5-5 > 10-5
n > 5
So, any number greater than 5 is a solution, and will make the inequality true.
The numbers in the set that are greater than 5 are 6, 8, and 10
To test that these numbers do make the inequality true, substitute each value in for n
n +5 > 10
6+5 > 10
11 > 10
True
n +5 > 10
8+5>10
13>10
True
n +5 > 10
10+5> 10
15>10
True
wwe 2k17. hop on. it will help out a lot with stress and tension if you know what i mean
Answer:y=2x+7
Step-by-step explanation:
so for the new equation, we know the slope is going to be the same (because its parallel) so for starters we have y=2x+b so now in order to find b (the y-intercept) we have to plug the point into the equation. So it would look like -1=2(-4)+b and then you solve for b and get 7 for b. SO the final answer is y=2x+7.
Answer:
Step-by-step explanation:
So we have the equation:
First, let's determine the domain restrictions. Recall that the radicand cannot be negative. In other words, it must be greater than or positive than 0. Thus:
Subtract 6 from both sides:
What this means is that our solutions must be greater than or equal to -6. If not, we ignore them.
So, let's subtract 5 from both sides from the original equation:
Square both sides:
Subtract 6 from both sides:
138 is greater than -6, so 138 is a solution and is the only solution.
And we're done!
