Answer:
-3, 0, 2
Step-by-step explanation:
use each of the given values as the y or f(x).
-9 = 2x - 3
solve for x
do this with each value
Answer:
As it says he is incorrect.
Step-by-step explanation:
To start, if you were to multiply something such as 5*1, then you would get the same number. Another example would be 8*0. Anything multiplied by 0 IS zero. He does give some valid answers, but there are also ones with smaller numbers. That is why Jackson is incorrect.
The answer is 136
All the numbers shown range close to that number
Answer:
length: 6 inches
width: 7 inches
Step-by-step explanation:
Let n represent the number. Then the length is (n+2) and the width is (2n-1). The product of these dimensions is the area:
42 = (n+2)(2n -1) = 2n^2 +3n -2
2n^2 +3n -44 = 0 . . . . subtract 42
(n -4)(2n +11) = 0 . . . . . factor
n = 4 . . . . . . . . we aren't interested in the negative solution
Length = 4+2 = 6 . . . inches
Width = 2·4 -1 = 7 . . . inches
1. 4.5g + 6 < = 40
4.5g < = 40 - 6
4.5g < = 34
g < = 34/4.5
g < = 7.56
True statement : John can buy 7 gallons but not 8
2. 250 + 3b < = 800
3b < = 800 - 250
3b < = 550
b < = 550/3
b < = 183.33
True statement : The maximum number of new baseballs that can be purchased is 183
3. 3x + 6 > 15
3x > 15 - 6
3x > 9
x > 9/3
x > 3
4. 4x - 6 < 2x + 8
4x - 2x < 8 + 6
2x < 14
x < 14/2
x < 7
5. 3 - 2x > 9
-2x > 9 - 3
-2x > 6 ...when dividing by a negative, u flip the inequality sign
x < -6/2
x < -3
True statement : - 2
7. 3x - 3 < -12 OR -4x < = -32
3x < -12 + 3 x > = -32/-4
3x < - 9 x > = 8
x < -9/3
x < -3
answer : x < - 3 OR x > = 8
8. -7x + 9 < 72 AND 5x - 3 < = 7
-7x < 72 - 9 5x < = 7 + 3
-7x < 63 5x < = 10
x > -63/7 x < = 10/5
x > - 9 x < = 2
answer : -9 < x < = 2
