Answer:
y = 0
Step-by-step explanation:
We assume you want to find y such that ...
Dividing the second equation by 2, we can write an expression for x.
x +2y = -2
x = -2y -2
Substituting this into the first equation gives ...
y = 3(-2y -2) +6
y = -6y -6 +6 . . . eliminate parentheses
7y = 0 . . . . . . . . . add 6y
y = 0 . . . . . . . . . . divide by 7
The value of y in the system of equations is 0.
Answer:
put it into a graphing calculator, the point where the line intercepts the y-axis would be B
Answer:
A. Aditi 2 1/2 cups, Kavitha 3 3/4 cups, and Rahul 4 1/8 cups
Step-by-step explanation:
2*2=4 5-4=1 2 1/2
3*4=12 15-12=3 3 3/4
4*8-32 33-32=1 4 1/8
Start with assigning each person with a variable to represent their height
Ebi: e
Jose: j
Derell: d
Asami: a
Ebi'd height was 2.5 cm greater than Jose's height
j + 2.5 = e
Jose's height was 3.1 cm greater than Derell's
d + 3.1 = j
Derell's height is 0.4 cm less than Asami's height
a - 0.4 = d
Ebi is 162.5 cm tall
e = 162.5
So, plug in 162.5 into any of the above equations were there is a variable of e
j + 2.5 = e
j + 2.5 = 162.5
Subtract 2.5 from both sides of the equation
j = 160 cm
Jose's height is 160 cm
Now, plug in 160 into any of the above equations where there is a j
d + 3.1 = j
d + 3.1 = 160
Subtract 3.1 from both sides of the equation
d = 156.9 cm
Derell's height 156.9 cm
so, plug in 156.9 into any of the above equations where there is a d
a - 0.4 = d
a - 0.4 = 156.9
Add 0.4 on both sides of the equation
a = 157.3 cm
Asami's height is 157.3 cm
Area =(1/2)(sum of parallel bases) x (height)
A= (1/2)(b1 + b2)x h
A= (1/2)(10 + 8)(6)
A=(1/2)(18)(6)
A= 18 x 3
A= 54 sq. inch
The answer is B
