Answer:
x = -2
Step-by-step explanation:
6 more then the product of 5 and a number x is -4
" the product " means multiply
5x + 6 = -4
5x = -4 - 6
5x = -10
x = -10/5
x = -2 <===
Answer: y=-(4/3)*x-6
Step-by-step explanation:
The equation of any straight line is y=a*x+b (1).
So we have to find the coefficients a and b and substitute them to the equation (1).
If the required line is perpendicular to y= (3/4)*x-2 it means that
a= -(4/3) (we have to inverse the fraction 3/4 and put the opposite sign after that. 3/4 has the sign + in front of it so we have to put sign -)
So the equation of required line is y= -(4/3) *x+b .
Now we have to find b. To do that pls remember that the point (-12;10) belongs to the required line y= -(4/3) *x+b . That means:
10=-(4/3)*(-12)+b => 10=16+b => b=-6
So substitute b in equation (1) and get:
y=-(4/3)*x-6
Answer you multiple it by 10
Step-by-step explanation:
Ahello me again . I get 105°
since ∠A = 50° then ∠DAB = 25°
since ∠B = 100° then ∠ DBA = 50°
the sum of the angles in triangle ADB = 180°
thus ∠ADB = 180 - (25 + 50 ) 180 - 75 = 105°
