Answer:
Slope= 2 / 10 = 1 / 5 = 0.2
y-intercept= (0, -4/5) or (0, -0.8)
Step-by-step explanation:
Answer:
10x +6y - 14
Step-by-step explanation:
3x - 2y = 13x + 4y = 14
3x = 13x + 6y = 14
-10x = 6y = 14
10x + 6y - 14
The value for y is 17.5°
The equation is
Sin (3y - 30°) = Cos (7y +50°)
<h3>What is Trigonometry ?</h3>
Trigonometry is the branch oh Mathematics which involve the study of right angles , its sides and trigonometric ratios.
the equation given in the question is
Sin (3y - 30°) = Cos (7y +50°)
cos(90 -
) = sin 
Therefore
sin(3y-30°) = sin( 90-(7y+50°)
Equating the terms
3y - 30 = 90-7y -50
4y = 90-50+30
4y = 120-50
4y = 70
y = 17.5
The value for y is 17.5°

Answer:
3x²-10x+8
Step-by-step explanation:
To simplify the expression we need to multiply each term in the first bracket with the expression in the second bracket.
x(3x-4)-2(3x-4)
3x²-4x-6x+8
Executing the operations to give a quadratic expression we get:
3x²-10x+8
The simplified expression is therefore
3x²-10x+8
