Answer:
dab= 43 degrees
Step-by-step explanation:
this is because of a property in geometry (I dont remember the name) that says when your lines are parallel to each other with that line through the center like that, the degrees cross
Answer:
x = 30
y = 14
Step-by-step explanation:
If the linear pairs are equal, then we can conclude that the angle on each of the sides is 90
Thus 3x = 90
and x = 90/3 = 30
Also;
9y - 36 = 90
9y = 90 + 36
9y = 126
y = 126/9
y = 14
Answer:
y=-3x-14
Step-by-step explanation:
y=mx +c
m= 1/3
perp m= -3
goes through point (6,-4)
sub numbers
Answer:
x = -3 or x = -2
Step-by-step explanation:
Our equation is: .
We see that all three terms are multiples of 3, so let's just divide both sides by 3 to simplify: . We now have: .
To factor this, we want to look at the pairs of factors of the constant 6 and see which pair will add up to 5 (from the 5x). After some searching, we can easily see that 3 * 2 = 6 and 3 + 2 = 5, so this is the pair we're looking for. Then, we factor: .
Finally, to solve, we know that if x + 3 = 0 or if x + 2 = 0, then the product will be 0, so: x + 3 = 0 --> x = -3 OR x + 2 = 0 --> x = -2
Thus, the answer is: x = -3 or x = -2.
Hope this helps!
