Answer:
Step-by-step explanation:
x²+5x-84
look for the factors of 84 that when you add together it will give +5
look for the factors of 84 that when you multiply together it will give -84
12 and 7
addition, multiplication
-12+7 = -5 -84
-12-7= -19 84
+12-7 = +5 -84 correct
then equate into the =5x and -84
x²+12x-7x-84
then factorize
x(x+12)-7(x+12)
(x-7)(x+12)
Answer:
Distance xy is 6
Distance yz is 11
Step-by-step explanation:
Given that the full length between x and z, xz = 17
Point y is located along xz where :
yz = 3x-10
xy = 2x-8
A simple sketch to show the distance and points can be;
x----2x-8---------y------3x-10-----------z
-----------------------17-----------------------
So you can see from this sketch that;
(2x-8) +(3x-10) = 17
2x-8+3x-10=17
5x-18=17
5x=17+18
5x=35
x=35/5 = 7
x=7
Distance xy=2x-8 = 2(7)-8 = 14-8 = 6
Distance yz=3x-10 = 3(7)-10 = 21-10 =11
Answer:
4/2=2
Step-by-step explanation:
When determining the slope of a line from a graph, slope is rise over run. Your line rises 4 points and then runs 2 points from point a to point b.
Step-by-step explanation:
i dont know
To put it in slope intercept form, you want to solve for y.
5y = -6x + 50
y = -6/5x + 10
So, your slope is -6/5 (or -1.2) and your y-intercept is +10.
