Answer:
10
Step-by-step explanation:
given
we first need to simplify the expression before we find it's value when s=-3
positive times negative=negative
so the equation becomes
substituting s=-3 into the equation.
=
=the negatives cancel out leaving
Answer:
The slope is 24
Step-by-step explanation:
Use any two points in the graph to find the slope of the graph
- - - - - - - - - - - - - - - - - - - -
Step 1. Use two points
Ex: (10, 320) & (5, 200)
Step 2. Find the slope using the two points
m = slope
m = change in y/change in x
m = (y2 - y1)/(x2 - x1)
m = (200 - 320)/(5 - 10)
m = -120/-5
m = 120/5
m = 24
The slope of the graph/line is 24
Answer: 14x^2-93xy+60y^2 Hope that helps!
Step-by-step explanation:
1. Expand by distributing terms
(20x-12y)(x-4y)-(3x-4y)(2x+3y)
2. Use the Foil method:(a+b)(c+d)= ac+ad+bc+bd
20x^2-80xy-12yx+48y^2-(3x-4y)(2x+3y)
3. Use the Foil method : (a+b)(c+d)= ac+ad+bc+bd
20x^2-80xy-12yx+48y^2-(6x^2+9xy-8yx-12y^2)
4. Remove parentheses 20x^2-80xy-12yx+48y^2-6x^2-9xy+ 8yx+12y^2
5. Collect like terms (20x^2-6x^2)+(-80xy-12xy-9xy+8xy)+(48y^2+12y^2)
6. Simplify.
And your answer would be 14x^2-93xy+60y^2
Answer:
x= -2/3 and 6
Step-by-step explanation:
3x²-16x-12
3x²-18x+2x-12
(3x²-18x)+(2x-12)
3x(x-6)+2(x-6)
(3x+2)(x-6)
x= -2/3 and 6
