Answer:
Step-by-step explanation:
i think its x=3
Answer:
See below
Step-by-step explanation:
Minutes Temperature
0 -2
1 1
2 3
3 4
4 5
5 -4
6 2
7 -3
Minutes should be graphed on x - axis as it repeatedly increases by 1 and seems to be independent. (Remember the independent variable is on x-axis). The axis increment should be one as told before, that the terms are increasing by 1.
Now, Temperature should e graphed on y-axis because it seems to depend on Minutes. The axis increment should also be 1 for this as although, it not increasing by 1 but still at some points increases by 1. So, the axis increment should be 1 for Temperature.
Answer:
1. C. 4x + 40
2. a. - 2a + 10
3. d. 13x - 45
4. 2c-7d
5. b. -2z - 12
Step-by-step explanation:
1. 4(x+10) = 4x+4*10 = 4x+40
C
2. -2(a - 5) = -2*a -2*-5 = -2a+10
A
3. 10x + 3 (x-15)
10x + 3x -3*15
10x+3x-45
13x-45
D
4. -5(c+d) + 7c - 2d
-5c-5d + 7c-2d
-5c+7c -5d -2d
2c-7d
5. 2(2z + 4) - 2 (3z + 10)
2*2z +2*4 -2 *3z -2*10
4z+8 -6z-20
4z-6z+8-20
-2z-12
B
It would be written as a fraction to make the exponent negative put it over one : 1/7^4
