Solution to y= x + 1
How many solutions for y=x-1?
The graph of y=x−1 in the xy -plane is a straight line. Each point on this line represents a solution to the equation.
Let x=t where t is a real number. Then any point on the line is of the form
(x, y)=(t, t−1).
There is an infinitude of these points.
Simplify 4−3y+(−7y)+7.2.

The surface area of one box is 62 square inches.
What is surface area of a cuboid?The surface area of a cuboid is the total space occupied by it. A cuboid is a six-faced three-dimensional shape in which each face is in the shape of a rectangle.
Given that, Yolanda makes wooden boxes for a crafts fair.
The dimensions of box are length= 5 inches, breadth = 3 inches and height = 2 inches.
We know that, the formula to find the toral surface area of cuboid is 2(lb+bh+hl)
Now, surface area = 2(5×3+3×2+2×5)
= 2(15+6+10)
= 2(31
= 62 square inches.
Therefore, the surface area of one box is 62 square inches.

what is the missing angle
Answer:
89 degrees.
Step-by-step explanation:
The angles on a triangle always add up to 180. Therefore we have to subtract what angles we already have from 180 to get the missing angle
180-(49+42)
180-91= 89
The missing angle is 89 degrees.

Answer:
First you have to plot Bart's Garage's fee. Bart's equation is y = 30x + 20, so you would need to plot the points (0, 20) and (1, 50).
Lisa's base fee is the same, so her equation would have a + 20 at the end of it, but her hourly fee is higher. Therefore her hourly fee would be higher than 30. Her equation could be anything above 30, y = 50x +20 would work. The points for that graph are (0, 20) and (1, 70).

A cubical box is 75cm high. how many rectangular packets each of 25×15×5cm are required to fill the box.
Answer:
Explain:
please help
Answer:
225 packets
Step-by-step explanation:
Height of cubical box = 75cm
Dimension of rectangular packet = 25×15×5cm
Volume of cubical box = 75^3
Volume of cubical box = (75 * 75 * 75)cm³ = 421,875 cm³
Volume of rectangular packet = 25×15×5cm = 1875 cm³
Number of rectangular packets required /
421,875 cm³ / 1875 cm³
= 225
Number of packets required = 225 packets
