Answer:
y=5x-10
Step-by-step explanation:
5x - y = 10
-y = -5x + 10
y = 5x -10

Answer:
5, 29 will both blank boxes
Step-by-step explanation:
the product of (4z^2 + 7z – 8) and (–z + 3)
(4z² + 7z – 8)(–z + 3)
-z(4z² + 7z – 8) + 3(4z² + 7z – 8)
-4z³-7z²+8z+12z²+21z-24
choose like terms
-4z³-7z²+12z²+8z+21z-24
-4z³+5z²+29z-24
5, 29
The possible values of the third angle are from 18° to 20°
Step-by-step explanation:
The sum of the measures of the angles in any triangle is 180°
The given is:
1. α and β are two angles of a triangle
2. 58° ≤ α ≤ 59°
3. 102° ≤ β ≤ 103°
Assume that the third angle is Ф
∵ α + β + Ф = 180°
- Subtract α + β from both sides
∴ Ф = 180 - (α + β) ⇒ (1)
∵ 58° ≤ α ≤ 59°
∵ 102° ≤ β ≤ 103°
- Add the two inequalities
∴ 160° ≤ α + β ≤ 162°
- By substituting α + B = 160 in equation 1
∴ Ф = 180 - 160
∴ Ф = 20°
- By substituting α + B = 162 in equation 1
∴ Ф = 180 - 162
∴ Ф = 18°
- Put Ф in the form of inequality
∴ 18° ≤ Ф ≤ 20°
The possible values of the third angle are from 18° to 20°
