First step is to factorize the given expression as follows:
2x^2 + 7x - 15 = (2x-3)(x+5)
This means that the two roots of the equation are 3/2 (or 1.5) and -5
Now, we will get r and s:
we are given that the value of r is greater than the value of s, since 1.5 is greater than -5, therefore:
r = 1.5
s = -5
Answer:
b.
Step-by-step explanation:
4x + 2(y – 1) = 0
The variables are all of unit degree so it is linear.
answer= 1
5 x 2 - 3^2
1. First simplify exponents
= that is nine
2. Then Do 5 x 2- 9
5 x 2=10
10-9
= 1
To make this table, pick any value you want for x, then substitute it an solve for y.
For example, if you choose x=1, then
y=-2/3(1)-1
y=-2/3-3/3
y=-5/3
To do a three part table quickly, I like to use -1, 0, and 1 for the value of x, since -1 and 1 will not change the values, only the sign for -1, and 0 eliminates the m section of the equation.
I hope this helps !!!!
Answer:
8 cans of frozen dinner
9 cans of soup
Step-by-step explanation:
Given:
200mg/1 can of soup
600mg/1 can of frozen dinner
17 cans of both soup and frozen dinners which contain 6600mg
200 (9) + 600 (8) = 6600
