If the lines cross, there is a solution , which means that there is a y and x value which satisfies both equations.
since both the equations start with x+y they shoulddd have the same answer if they had crossed. we can tell straight away these lines do not cross because 6=/=4 6 doesnt equal 4. therefore no solution.
TIP: for the future, if they had crossed, you can use simultaneous equations to find x and y to see if they work in each equation and find a solution ( since they are straight lines there will only be 1 solution, unless they are literally the same line in which case then then they are ALWAYS on top of each other and always have the same values)
The degree is 3 ( because the largest exponent on the variable)
Answer:
3/28
Step-by-step explanation:
You can rewrite 3/8 ÷7/2 to 3/8 x 2/7
then you can simplify which is 3/28
Answer:
x = 7.2
Step-by-step explanation:
Let x be a positive number such that the distance between x and -3.8 on a number line is exactly 2 times the distance between x and 1.7.
Now. the distance between - 3.8 and x will be (x + 3.8) and the distance between x and 1.7 will be (x - 1.7) {Since x is a positive number}
(Assuming x is greater than 1.7}
Given that, x + 3.8 = 2(x - 1.7)
⇒ x + 3.8 = 2x - 3.4
⇒ x = 7.2 (Answer)
Equation of line h is y=-2x-1
Slope is -2 (because it’s parallel)
so you have y=-2x+a
now you have to plug in the points it needs to pass through -9=-2(4)+a
do -2(4)
isolate a so then you would add the -8 to the other side
do the math of -9-(-8)
that’s how you get y=-2x-1
