C is your answer. 5x + 2 = 17
First let’s get them all in terms of x:
Box kites = 3x
Dragon kites = x + 2
Butterfly kites = x
Adding all those up:
x + 3x + x + 2 = 17
Combine like terms:
5x + 2 = 17
Negative correlation between two variables means when x is increasing but y is decreasing or vice versa.
First graph of suffered animals and children shows a positive slope which means if age of child increasing then numbers of suffered animal is also increasing.So, the first graph show a positive correclation.
Second graph of survey of adults doesn't represnt any distinct relationship as the data scattered randomly everywhere in the graph. So, it's showsa very week correlation.
Third graph of speed and MPG shows a negative slope as speed is increasing then MPG is decreasing. So, the third graph (speed and MPG) shows a negative correlation.
Answer:
Step-by-step explanation:
First both the rational numbers should have same denominators. So, find least common denominator
Least common denominator is 10
Now multiply the numerator and denominators of the both the numbers by 10.
Answer:
Step-by-step explanation:
x^2 + 10x + 5 - 30 = 0
x^2 + 10x - 25 = 0
x^2 + 10x = 25
x^2 + 10x + 25 = 25 + 25
(x + 5)^2 = 50 <====
Answer:
60 m^2
Step-by-step explanation:
To solve the area, solve the triangle and rectangle separately.
Solve the rectangle:
Multiply 10 and 4 to get the area of 40 m^2.
Solve the triangle:
Multiply 10 and 4, then divide by 2. The formula for a triangle's area is base*height/2. The area is 20.
Add together:
40+20 = 60 m^2
