Answer:

5. x = 5, y = 3

6. x = 0, y = 4

7. x = -1, y = 1

Step-by-step explanation:

5. substitute 3(value of y) into the equation y = x - 2:

=> 3 = x - 2

=> x = 5

6. substitute 0(value of x) into the equation y = x + 4:

=> y = 0 + 4

=> y = 4

7. substitute 1(value of y) into the equation y = 2x + 3:

=> 1 = 2x + 3

=> 2x = -2

=> x = -1

A construction company is building the house shown below. They need to use a scale
Svetllana [295]

The height of the building is calculated by representing 1 inch as 8 feet. The final building has a height of 20 feet.

<h3>What is scaling?</h3>

Scaling is the increase or decrease in the height of an object by a scale factor k.

Given that the scale used is:

1 inch = 8 feet. Hence:

Since the height of the building is 2.5 in, hence:

Height of the final building = 2.5 in * 8 ft per 1 in = 20 feet

The height of the final building is 20 feet.

The basal energy rate is the daily amount of energy (measured in calories) needed by the body at rest to maintain body temperatu
katovenus [111]
Given :
A = <span>70 years old
H = 172 cm
W = 55 kg

so calculate the the basal energy rate B
B = </span><span>655.096 + 9.563W +1.85H - 4.676A
</span><span>where B is the basal energy rate (in calories), W is the weight (in kilograms), H is the height (in centimeters), and A is the age (in years)
substitute the given
B = </span>655.096 + 9.563(55) +1.85(172) - 4.676(70)
B = 1171.941 cal is the basal energy rate, since he is prescribed for 1000 cal per day is not enough because basal energy is the calorie needed at rest only how about the calorie needed for the daily acivities.
