Exterior angles thm:

83 + 6x - 4 = 21x + 4

6x + 79 = 21x + 4

6x - 21x = 4 - 79

-15x = -75

x = 5

m<D:

Solve for t. f(t)=-16t^2+576​
IgorC [24]

Answer: t^2=-f-576/16

Step-by-step explanation:

Step 1. Switch the equation around:

-16t^2+576=f

Step 2. Subtract 576 from each side:

-16t^2+576-576=f-576

Step 3. Now simplify:

-16t^2=f-576

Step 4. Divide everything now by -16:

-16t^2/-16=f/-16-576/-16

Step 5. Simplify again:

t^2=-f-576/16

Hope I could help! :)

Solve for x: 6x + 1/4 (4x + 3) &gt; 12<br> Ox&gt;<br> 10<br> 7<br> Ox&gt; 2<br> ox= 10<br> X = 2
daser333 [38]

Given:

The inequality is:

6x+\dfrac{1}{4}(4x+3)>12

To find:

The values for x.

Solution:

We have,

6x+\dfrac{1}{4}(4x+3)>12

Using distributive property, we get

6x+\dfrac{1}{4}(4x)+\dfrac{1}{4}(3)>12

6x+x+\dfrac{3}{4}>12

7x>12-\dfrac{3}{4}

7x>\dfrac{48-3}{4}

On further simplification, we get

7x>\dfrac{45}{4}

Divide both sides by 7.

x>\dfrac{45}{7\times 4}

x>\dfrac{45}{28}

Therefore, the required solution is x>\dfrac{45}{28}.

Note: All options are incorrect.
