Answer:

y=-9x-1

Step-by-step explanation:

since it is perpendicular, the slope must be the opposite reciprocal (-9x) and now we plug the coordinates in, -1=0+b, b is -1

A sandwich costs $0.75 more than a container of milk. A customer buys 4 sandwiches and 4 containers of milk. The customer pays $
Over [174]

Answer:

Assume that the cost of the milk is x.

We are given that a sandwich costs 0.75$ more than the cost of milk. This means that:

cost of sandwich = cost of milk + 0.75

cost of sandwich = x + 0.75


Now, the customer bought 4 sandwiches and 4 containers of milk at the cost of 7$.

We will transform this into an equation as follows:

total cost = cost of 4 sandwiches + cost of 4 containers of milk

7 = 4(x+0.75) + 4(x)


Solve the above equation to get x as follows:

7 = 4x + 3 + 4x

7-3 = 8x

8x = 4

x = 0.5


Therefore:

cost of milk = x = $0.5

cost of sandwich = x+0.75 = 0.5+0.75 = $1.25

Write the equation of a vertical line that passes through the point (–4, 4).
FinnZ [79.3K]
The question asks for a vertical line, and if it is vertical, it cannot be y = ... because that is horizontal. We also know it passes through the x-coordinate of -4, so the answer is x = -4.

Find the surface area of the square pyramid shown below.
Volgvan

Answer:

Step-by-step explanation:

area of a triangular face = 0.5×4×3 = 6 square units

lateral area = area of 4 triangular faces = 4×6 = 24 square units

base area = 4² = 16 square units

total surface area = lateral area + base area = 24+16 = 40 square units
