Answer:
The coordinate of a point is its location on a grid.
The point will be located halfway between -2 and -3 on the x-axis, on -4 on the y-axis
The coordinate is given as:
Express as decimals
The above point means that:
This means that:
The point will be located halfway between -2 and -3 on the x-axis, on -4 on the y-axis
Step-by-step explanation:
Answer:
x=12 and y=31
Step-by-step explanation:
First, ( 5x - 7 ) and ( 3x + 17 ) are alternate interior angles, which means they are congruent, or equal:
5x - 7 = 3x + 17
Add 7 to each side:
5x = 3x + 24
Subtract 3x from both sides:
2x = 24
Divide each side by 2:
x = 12
Now we can see that ( 5x - 7 ) and ( 4y + 3 ) are supplementary angles, which means they will add up to 180 degrees:
5x - 7 + 4y + 3 = 180
Substitute 12 in for x to solve for y:
5 ( 12 ) - 7 + 4y + 3 = 180
60 - 7 + 4y + 3 = 180
combine like terms:
( 60 + ( -7 ) + 3 ) + 4y = 180
56 + 4y = 180
Subtract 56 from each side:
4y = 124
Divide each side by 4:
y = 31

Answer:
13
Step-by-step explanation:
You use pemdas to figure this out, so you do whats in the parentheses first, 2x-6, but instead you do 2(4)-6 and when your solving stuff in the parentheses you apply pemdas again to figure out what to do, so you multiply 2x4 first bcz m is before s, and then you do 8-6 bcz there's nothing else to do in the parentheses. now that your done with the parantheses you currently have 3x3 +2(2). now you dont have p or e but you do have m and when you have multiple instances of multiplication you do it left from right, so you do 3x3 first and get 9 and then you do 2x2 and get 4. now you have 9+4 and since you have nothing else to do you add and you get 13.
