The coefficients in the expression are -1 and 9

<h3>How to determine the coefficients?</h3>

The expression is given as:

-x^2 + 9x

In an expression ax, the coefficient is a.

Using the above as a guide, we have:

-x^2 + 9x

The coefficients in the above expression are -1 and 9

Answer:

ad+b

give me brilliant please

Step-by-step explanation:

c−d

Step 1: Multiply both sides by c-d.

ac−ad=b

Step 2: Add ad to both sides.

ac−ad+ad=b+ad

ac=ad+b

Step 3: Divide both sides by a.

ad+b

Using the equation y = 3x – 5, what would the output be for an input of 2

Licemer1 [7]

Answer:

Step-by-step explanation:

y = 3x - 5.....input values are x and output values are y

so if ur input (x) is 2.....sub 2 in for x and find ur output (y)

y = 3x - 5

y = 3(2) - 5

y = 6 - 5

y = 1 <=== ur output value

Two weather stations are aware of a thunderstorm located at point C. The weather stations A and B are 27 miles apart. How far is

cluponka [151]

Station A is at a distance of 28.83 miles from the storm

Sine rule is used to show the relationship between the sides of a triangle as well as their opposite angles. It is given by:

$\frac{a}{sin(A)}= \frac{b}{sin(B)}=\frac{c}{sin(C)}$

From the diagram:

A = 34° + 90° = 124°

Also:

B = 90° - 61° = 29°

Hence:

C + A + B = 180°
C + 29 + 124 = 180
C = 27°

b = distance station A from the storm, c = AB = 27 miles

Using sine rule:

$\frac{c}{sin(C)} =\frac{b}{sin(B)} \\\\\frac{27}{sin(27)}=\frac{b}{sin(29)} \\\\b=28.83\ miles \\$

Station A is at a distance of 28.83 miles from the storm
