Help pleaseeeeeeeeeeee

Mathematics
1 answer:
ollegr [7]3 years ago
6 0

Answer:

Step-by-step explanation:

The temperature at a given altitude is

y = 36 - 3x

The temperature on the surface of the planet is the point (0,t) where t is the temperature for the given height.

y = 36 - 3*0

y = 36

So at the surface of the planet is 36 degrees C.

======================

Effectively it is the slope of the equation which is - 3

So ever km going up will mean a loss of 3 degrees. I think they want you to write -3

What is the value of the expression below when x = 3?<br> 10x2 – 7x + 10
QveST [7]

Answer:

79

Step-by-step explanation:

To find the value of 10x^2 – 7x + 10, when x = 3, simply plug in the value of x in the expression and solve as follows:

10(3)^2 – 7(3) + 10

10(9) – 21 + 10

90 – 21 + 10

79

The value of 10x^2 – 7x + 10, when x = 3, is 79

Select the correct answer. what is the solution set of y = x2 2x 7 and y = x 7? a. {(0, 7), (-1, 6)} b. {(0, 7), (-7, 0)} c. {(0
Kaylis [27]

Answer:

a. {(0, 7), (-1, 6)}

Step-by-step explanation:

y = x^{2} +2x+7\\y=x+7

subtract the equations

y = x^{2} +2x+7 \\-       \ \ \ \ \  y=x+7\\y - y =x^{2} +2x+7-(x+7)\\0=x^{2} +x\\x = 0 \ and \ x= -1

for y = x^{2} +2x+7, substitute x = 0

y = (0)^{2} +2(0)+7\\y = 0 +0+7\\y=7

for y = x^{2} +2x+7, substitute x = 0

y = (-1)^{2} +2(-1)+7\\y = 1 -2+7\\y=6
