Answer:
A. 312
Step-by-step explanation:
For the rectangle center multiply 6*4=24
Area of a trapezoid: ((a+b)/2)h so with this we can determine that the area of one side is 40, since there are 2 sides the area would be 80 total
24+80=104
For 3 bows: 104*3=312
29.) This is simply interpreting the linear function.
The function:
96+2.1x
a.) The 96 is what you start with from the beginning. So, we know Rachel weighed 96 ounces when she was born.
b.) Again, interpretation. The 2.1 is the slope, or the change in the line. So we know that Rachel gains 2.1 ounces each day.
30.) For this one, you just have to plug 9 into the equation for x.
125 135 145 155 165 175 185 195 205 220 235 245= 11 weeks
Answer:
System of Linear Equations entered :
[1] 4x - 3y = 15
[2] 2x + 2y = 4
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 2y = -2x + 4
[2] y = -x + 2
// Plug this in for variable y in equation [1]
[1] 4x - 3•(-x +2) = 15
[1] 7x = 21
// Solve equation [1] for the variable x
[1] 7x = 21
[1] x = 3
// By now we know this much :
x = 3
y = -x+2
// Use the x value to solve for y
y = -(3)+2 = -1
Solution :
{x,y} = {3,-1}
