substitute for your equation;
h(x) = f(x) - g(x)
h(x) = (3x + 2) - (-2x -4)
h(x) = 3x + 2 + 2x + 4 (minus and minus = addition)
h(x) = 3x + 2x + 2 + 4 (combine like terms)
h(x) = 5x + 6
Hope that helps! :D
B: 68
C: 76
D: 108
E: 193
F: 540
Answer: A, B, C, E
Explanation:
The sum of the interior angles of a polygon can be determined by the formula: (n - 2)180 ; where n represents the number of sides. Since a pentagon has 5 sides, then (5 - 2)180 = 540
x - 8
3x - 11
x + 8
x
2x + 7
8x - 4 = 540
+4 +4
8x = 544
÷8 ÷8
x = 68
**********************
x - 8 ⇒ 68 - 8 = 60 (A)
3x - 11 ⇒ 3(68) - 11 = 193 (E)
x + 8 ⇒ (68) + 8 = 76 (C)
x ⇒ (68) (B)
2x + 7 ⇒ 2(68) + 7 = 143
The sumof the pentagon's interior angles is: 540°
According to the Question, we have: (x-8)+(3x-1)+(x+8)+x+(2x+7)=540
x-8+3x-11+x+8+x+2x+7=540
x+3x+x+x+2x=540+8+11-8-7
8x=544
x=544/8=68
(x-8)=68-8=60 (choose letter A)
(3x-11)=3*68-11=193 (choose letter E)
(x+8)=68+8=76 (choose letter C)
(x)=68 (choose letter B)
(2x+7)=2*68+7=143 (cannot select any letter)
In short, we choose letter A, B, C and E.
Answer:
Total number of jumping Jacks by Linda in 7 days = 825
Step-by-step explanation:
Total number of days Linda jumped = 7 days
Now, for first 3 days, jumping jacks each day = 75
So, total jumping jacks in first 3 days = 75 x 3 = 225
Now, number of days left in the week = 7 days - 3 days = 4 days
Also, for next 4 days, jumping jacks each day = 2 x 75 = 150
So, total jumping jacks in last 4 days = 150 x 4 = 600
Hence, the Total number of jumping Jacks in 7 day
= Jumping Jacks in fist 3 days + Number of jumping jack in last 4 days
= 225 + 600
= 825
Hence, Total number of jumping Jacks by Linda in 7 days = 825
