Answer:
B, C
Step-by-step explanation:
I love slope
Answer:
B
Step-by-step explanation:
2a+45=180
subtract 45 from both sides which equals 2a=135
divide both sides by 2 which would solve for a.
Answer:
x = -1 y = - 13/6
Step-by-step explanation:
Answer:
11. 2/5 = <u>40</u>/100 = <u>40</u>% 12. 29/50 = <u>58</u>/100 = <u>58</u>%
Step-by-step explanation:
To convert the given fraction to a fraction of 100, cross-multiply and divide.
2 × 100 = 200 / 5 = 40
Then, whenever you have a number over 100, all you need to do to get the percentage is find the numerator and add a percent sign at the end of the number.
40 ⇒ 40%
Repeat this with the second question.
29 × 100 = 2900 / 50 = 58 ⇒ 58%
Y=Mx+b
Slope/M= -1
X= 3
Y= -1
-1 = -1(3)+b
-1 = -3 + b
Add +3 to -3 and -1 to cancel -3 out to get (b)
-3+3 = 0 cancel it
-1 +3 = 2
So, b = 2
In an equation it will be written as
y= -1x + 2
In standard form it will be
1x + y = 2
But your official answer will be
B= 2
Y= -1x+2
