4x+9=41 x is equal to <br>​
Mariana [72]

Answer and Step-by-step explanation:

Simply solve for x (very easy to do).

4x + 9 = 41

<u>Subtract 9 from both sides of the equation.</u>

4x = 32

<u>Divide both sides of the equation by 4.</u>

x = 8

<u>x is equal to 8.</u>

WILL MARK BRAINLIEST IF CORRECT PLEASE HELP
Romashka [77]

Answer:

\frac{4\sqrt{7}}{7} \text{ and } \frac{3\sqrt{7}}{7}

Step-by-step explanation:

if \sec x = \frac{4}{3}, then that means that it is the angle of a right triangle with the hypotenuse equal to 4 and one of the legs (specifically the adjacent leg) equal to 3, since sec(x) is defined as hypotenuse over the adjacent side.

The other leg (specifically the opposite one) will be equal to \sqrt{16-9} = \sqrt{7} by the pythagorean theorem, so csc(x) = hypotenuse over opposite side = \frac{4}{\sqrt{7}}=\frac{4\sqrt{7}}{7}.

cot(x) is defined as adjacent over opposite, which is equal to \frac{3}{\sqrt{7}}=\frac{3\sqrt{7}}{7}

That means that the first option, the leftmost one, is correct.

Given the function f(x) =-4/3 x+4 use the slope and y -intercept to graph the function .identify the x - and y -intercepts
Airida [17]

Answer: for -4/3x+4 the y intercept is (0,4) and x is (3,0) the slope is -4/3

for 2/7x+2 the y intercept is (0,2) and the x is (-7,0) the slope is 2/7

Solve the equation x2+11x-15=0, give ans to two dp.
Charra [1.4K]
Im going to assume you know the formula.
sooo.
x= -11 +- √ (11)² -4 (1) (-15)
     --------------------------------- 
          2(1)

= -11 +- √121- (-60)
  -------------------------
              2

= -11 +- √181
   -----------------
            2

= -11 +- 13.45
   -----------------
             2

Either:                                                Or:
                                                          X = -11 - 13.45
  x = -11 + 13.45                                       ---------------
                                                                        2
       ----- ----------                               
              2       
   x = 1.23                                           x= -12.23
