Solve for m. m + 4 3 = 2 what is m<br> HELP MEEEEE!!!!!!!!!!!
Anna71 [15]

<u><em>hi there user! Looks like your looking for help, so Mizuki came here to help you!</em></u>

the answer is:

<em>m is 2/3</em>

The whole work I did:

m + 4 ÷ 3 = 2

m + 4/3 = 2

m + 4/3 - 4/3 = 2 - 4/3

m = 6/3 - 4/3

m = 2/3

Anyways hope this helped! qwq

Y=x2-2x-5<br> Change to vertex form
MaRussiya [10]

The vertex form is y=(x-1)^{2} -6

Step-by-step explanation:

The given equation y=x^{2} -2x-5 is a parabola. The vertex of the parabola is of the form y=ax^{2} +bx+c  

The parameters of the parabola are a=1, b=-2 and c=-5

The vertex of the x-coordinate is given by x=\frac{-b}{2a}

Thus, substituting the values of a and b in x=\frac{-b}{2a}, we get,

\begin{aligned}x &=\frac{-(-2)}{2(1)} \\&=\frac{2}{2} \\x &=1\end{aligned}

Now, substituting x=1 in y=x^{2} -2x-5, we get,

\begin{aligned}y &=1^{2}-2(1)-5 \\&=1-2-5 \\y &=-6\end{aligned}

Thus, the vertex is (1,-6)

The equation of parabola to be in vertex form is y=a(x-h)^{2} +k

where a is the coefficient of x^{2}, h is vertex of the x-coordinate and k is the vertex of the y-coordinate.

Hence, a=1, h=1 and k=-6

Thus, substituting the values in the equation of the vertex form,

y=1(x-1)^{2} -6\\y=(x-1)^{2} -6

Hence, the vertex form is y=(x-1)^{2} -6

A customers total is $24.00 and a customer hands you a 10% coupon for their purchase. What will be the total cost after the coup
Furkat [3]
For 10% coupon, 10% of the original price is decreased, therefore we can multiply the price by (1-10%)=90% to find the total cost:

24×90%
= 24×0.9
= $21.9

Therefore the answer is $21.9.

Hope it helps!
