Answer:
y = 47
Step-by-step explanation:
All of the angles in a triangle must add up to 180. The angle marked 3y can help us find the missing angle of the triangle: 180-3y
Then you can make an equation to help solve for y:
50 + (2y-3) + (180-3y) = 180
Combine like terms:
227-y=180
y = 47
Answer:
D
Step-by-step explanation:
An inequality is an expression which means more than one number is a solution. We graph the solutions on a number line to show all possible values. We graph using circles and arrows.
- Equal to and less/greater than are graphed with filled in circles on the value.
- Only less/greater than (not equal to) are graphed with open (not filled in) circles on the value.
- We draw an arrow the direction the solutions satisfy the inequality. Generally this is the direction the inequality itself points.
This is a filled in circle on -2 so this is . This means only answers C and D are options.
Answer D points to the right.
Answer:
negative number
Step-by-step explanation:
-1
1/4 of -1 = -1/4
-1/4 is greater than -1
I believe it is one form of it.
b = 19
substitute x = - into the equation and solve for b
5(- )² - b + 12 = 0
+ = b
= b
multiply both sides by 5 and divide by 4
b = = 19
