igor_vitrenko [27]
Let X be the variable used to represent the expression of the total number of books that Mario has read.
We used 4X to represent "four times the number of books". Then we add -2 to interpret the words "for two less than".
Therefore, we have an expression of 4X-2 for the total number of books that Mario has read.

Write a formula for quadratic function if its graph has the vertex at point (0,6) and passes through the point (−1,−2).
d1i1m1o1n [39]

Answer:

y = - 8x² + 6

Step-by-step explanation:

The equation of a parabola in vertex form is

y = a(x - h)² + k

where (h, k) are the coordinates of the vertex and a is a multiplier

Here (h, k) = (0, 6), thus

y = a(x - 0)² + 6, that is

y = ax² + 6

To find a substitute (- 1, - 2) into the equation

- 2 = a(- 1)² + 6, that is

- 2 = a + 6 ( subtract 6 from both sides )

- 8 = a

y = - 8x² + 6

Find the value of x and y
tankabanditka [31]

Answer:

x = 3, y = 10.

Step-by-step explanation:

The 2 triangles are similar so the corresponding sides are in the same ratio.

x/6 = 4/8

x/6 = 1/2

x = 6/2 = 3.

y/5 =  8/4 = 2

y = 5*2 = 10,
