What is the value of c in the equation y = 4x^2 -10x + c if the y-coordinate of the vertex is -7
love history [14]

Answer: c=-\frac{3}{4}

Step-by-step explanation:

Find the x-coordinate of the vertex with this formula:

x=\frac{-b}{2a}

In this case:

a=4\\b=-10

Substituting values, we get:

x=\frac{-(-10)}{2(4)}=\frac{5}{4}

Now we can substitute the coordinates of the vertex into the equation y = 4x^2 -10x + c and then solve for "c".

Then:

-7 = 4(\frac{5}{4})^2 -10(\frac{5}{4}) + c\\\\-7+\frac{25}{4}=c\\\\c=-\frac{3}{4}

sp2606 [1]

Answer:

the supplementary angle to 313 would be 49.

Step-by-step explanation:

the supplement of an angle is when tow angles add up to equal 180 degrees. therefore, if you subtract 131 from 180, you would get the answer of 49 degrees.
