Answer:
5 crayons
Step-by-step explanation:
A standard pack of crayons is 24, so I put b = 24.
24 + 6 - (x) = 25
30 - (x) = 25
- 30 -30
- (x) = -5
÷ -1 ÷ -1
(x) = 5
I really hope this helps!
Answer:
x = 2
Step-by-step explanation:
All the red lines tell you that each side must be equivalent because the angles are aka equilateral triangle.
So, 2x+4 = 8
2x = 8-4
2x = 4
2x/2 = 4/2
x = 2
Find the slope:
(-19 - 11) / (-8 - 2) = (-30/-10) = 3
Find the y intercept:
y = mx + b
11 = 3(2) + b
b= 5
So equation is:
y = 3x + 5

Answer:
a = 2
Step-by-step explanation:
given x = - 1 is a zero then f(- 1) = 0 , that is
a(- 1)³ - (- 1)² - 1 + 4 = 0
- a - 1 - 1 + 4 = 0
- a + 2 = 0 ( subtract 2 from both sides )
- a = - 2 ( multiply both sides by - 1 )
a = 2
