Answer:
The answers are A, C, & D.
Step-by-step explanation:
A: the 34 would have an imaginary 0 behind it, so then it would become 340, which is greater than 304.
B, C, D: same logic as A
Answer:
most likely the last choice
Step-by-step explanation:
Answer:
X=128°
Step-by-step explanation:
Because an exterior angle of a triangle is equal to of the two opposite interior angle.
The sum of the exterior and interior angle is equal to 180°
In this case the part marked red = 90° because is a right angled triangle.
90+38=128
180- 128=52
180- 52=128
x=128.
Add the fractions 1/4 and 3/8
First find the LCD of 1/4 and 3/8. 8 is the LCD.
Turn 1/4 into 2/8.
Now add.
3/8+2/8=5/8

Answer:
y = -9x +49
Step-by-step explanation:
The slope of line b is the same as the slope of line a. That can be found using the slope formula:
m = (y2 -y1)/(x2 -x1)
m = (-1 -8)/(2 -1) = -9
The y-intercept can be found from the given point using the formula ...
b = y - mx
b = 13 -(-9)(4) = 13 +36 = 49
Then the slope-intercept equation of line b is ...
y = -9x +49
