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}

I need help with figuring out which converse makes QT parallel to MN
ASHA 777 [7]

Since corresponding angles of similar triangles are congruent and triangles QRT and MRN are congruent, then:

\angle RMN\cong\angle RQT.

Now, notice that angles RMN and RQT are corresponding angles, then, using the corresponding angle theorem we get:

QT\mleft\Vert MN\text{.}\mright?

Answer: Second option.
