Mathematics
1 answer:
UkoKoshka [18]3 years ago
4 0

Answer:

f(-5)=28

Step-by-step explanation:

f(x)=x²-2x-7

f(-5) means that we have to replace x by -5.

f(-5)=(-5)²-2(-5)-7=25+10-7=25+3=28

Witch value from the set {3,8,9,14} makes the euation true 2n-5=
lutik1710 [3]

The value from the set {3,8,9,14} makes the equation 2n - 5 = 11 true is n = 8

<h3>What is an equation?</h3>

An equation is an expression that shows the relationship between two or more numbers and variables.

Given the equation:

2n - 5 = 11

When n = 3:

2(3) - 5 = 1 ≠ 11

When n = 8:

2(8) - 5 = 11

When n = 9:

2(9) - 5 = 13

When n = 14:

2(14) - 5 = 23

The value from the set {3,8,9,14} makes the equation 2n - 5 = 11 true is n = 8

The <u>correct answers</u> are:

6.5 cm = 65.00001052 torr
6.5 cm = 8665.93 Pa
6.5 cm = 0.08552632119 atm

Explanation

The conversion rate from centimeters mercury (cm Hg) to torr is
1 torr = 0.099999983814461 cm.

We have 6.5 cm; this means to convert we divide:
6.5/0.099999983814461 = 65.00001052

The conversion rate from cm Hg to Pascals (Pa) is
1 cm = 1333.22 Pa

We have 6.5 cm; this means to convert we multiply:
6.5(1333.22) = 8665.93

The conversion rate from cm Hg to atmospheres (atm) is
1 atm = 75.999995199606 cm

We have 6.5 cm; this means to convert we divide:
6.5/75.999995199606 = 0.08552632119

klemol [59]

The Slope of lines parallel to line is 1/2 and the Slope of lines perpendicular  to line is -2.

<h3>What is the equation of a straight line ?</h3>

An equation that can be written in the form of y = mx+c

where m is the slope of the line

and c is the intercept on y axis

The equation given in the question is

y=1/2x−7

in this the slope = 1/2

Intercept = -7

For parallel Lines

For a parallel line , the slope of the line is same

and is given by  m = 1/2

For a perpendicular line

Slope will be equal to

-1/m

here -1/m = -2

Therefore the slope for perpendicular line is -2.
