Answer:
99
Step-by-step explanation:
Through some clever algebra, we can combine our first two equations using the fact that

We have the a² and the b² in the equation
, and we <em>almost </em>have a 2ab in the equation
. To get that 2ab, we can simply double both sides of the first equation to get
. From there, we'll add the first two equations together, giving us the summed equation

And since
, we can equivalently say that

Answer:
6
Step-by-step explanation:
change it around:
y=-7x+6
6 is the y
Hope this helps plz hit the crown :D
25 x 2= 50, so the third grade dash is 50 meters long.
Answer:
Number line is attached
Step-by-step explanation:
We are given inequality as

y is less than 23
so, we take all possible values that is less than 23
so, we can write interval as
For 
as

now, we can draw a number line and locate y=23
and then shade left side of 23 region
that would be solution
Answer:
84
Step-by-step explanation:
Minus 7 times minus 12 equals io 84 as the minus cancels out when u multiply by 2 minus because a minus and a minus equals to a positive
