Answer:
-58
Step-by-step explanation:
The real is the numbers and the imaginary is the x variable
Let x = the mass of a box and
y = the mass of a cube.
<u>Box A </u>
53 cubes and has a total mass = 1760 grams.
Therefore, box mass + 53 cubes mass = 1760.
<em>x+ 53y = 1760 ------------------equation (1).</em>
Box B
18 cubes and has a total mass = 1620 grams.
Therefore, box mass + 18 cubes mass = 1620.
<em>x+ 18y = 1620 ------------------equation (2).</em>
Subtracting equation (2) from equation (1), we get
x+ 53y = 1760
- (x+ 18y = 1620)
______________
35y = 140
Dividing both sides by 35, we get
y = 4.
Plugging y = 4 in first equation, we get
x+ 53y = 1760
x + 53 (4) = 1760.
x + 212 = 1760.
Subtracting 212 from both sides, we get
x + 212-212 = 1760-212.
x = 1548.
<h3>Therefore,
the box mass is 1548 grams and mass of a cube is 4 grams.</h3>
Answer:
y = 3x + 7
Step-by-step explanation:
First, we will solve for the slope (m).
The formula for slope is: m =
m = --- enter the points into the formula
m = --- simplify
m = 3 --- simplify
Now we will solve for the y-intercept (b).
y = mx + b
y = 3x + b --- substitute the slope into the equation
-20 = 3(-9) + b --- substitute the x and y of either point into the equation
-20 = -27 + b --- simplify
7 = b --- add 27 to both sides
b = 7
Done.
y = 3x + 7
