Is (4, 5) a solution to 2y – 3x = -7?

Answers

Answer 1

Answer:

Answer: no

because when (4;5) is a solution to 2y - 3x = -7

=> 2y - 3x = -7 passes through (4;5)

but when x = 4; y = 5 => 2.5 - 3.4 = -2 (unreasonable)

=> (4;5) isnt a solution

What’s the answer to this

Answers

Answer:

Step-by-step explanation:

Given f(x) the f(x) + c represents a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here c = - 6, thus a shift down, thus

g(x) = x² - 6 → A

what are the values of a, b, and c in the quadratic equation –2x^2 4x – 3 = 0? a = 2, b = 4, c = 3 a = 2, b = 4, c = –3 a = –2, b = 4, c = 3 a = –2, b = 4, c = – 3

Answers

a=-2
b= either negative or positive 4 (you didn't include a plus or minus sign in your question)
c=-3
It should be the last answer choice.

5 packets of different sizes have a total mass of 800 g find their average mass

Answers

$(800g)/(5 packets) = (160g)/(1 packet) average mass$

To find the average of a quantity, we simply take the total and divide by the number of products contributing to that data:
800/5 = 160g
