Answer:
110 degrees
Step-by-step explanation:
the angles stay the same even if the size changes!
Rewrite the first equation: 3y=-2x-17. The equations are coincidental and -17 is one sixth of -102 so the other coefficients need to be multiplied by 6: 18y=-12x-102.
29. 2w + 13
31. 9r - 4
33. 21q + 10
Answer:
The zeros are x=7 and x= -6
Step-by-step explanation:
In order to find the zeros of a function with factors, we have to equate the factors to zero.
So x-7 = 0
and
x+6 = 0
Then we solve for x in each equation,
x= 7 and x= -6
These values are the zeros
Step-by-step explanation:
Step 1 : 0.5x + y = 1.5
0.8x - 0.2y =6
Step 2 : y = 1.5 - 0.5x
0.8x - 0.2 ( 1.5 - 0.5x ) = 6
Step 3 : y = 1.5 - 0.5x
0.8x - 0.3 + 0.1x = 6
Step 4 : y = 1.5 - 0.5x
0.9x = 6.3
Step 5 : y = 1.5 - 0.5* 7
x = 7 ( put 7 into the x value above )
Ans: y = -2
x = 7
You can ask me if you don't understand any step^^
