Choose the quadratic equation that has a leading coefficient of 8 and solutions -10 and 7/8

Maru [420]

Answer:

$f(x)=8x^2+73x-70$

Step-by-step explanation:

We are given

zeros as -10 and 7/8

now, we can set up function as

$f(x)=a(x-(-10))(x-\frac{7}{8})$

now, we are given that

leading coefficient is 8

so, a=8

now, we can plug it

$f(x)=8(x-(-10))(x-\frac{7}{8})$

now, we can simplify it

$f(x)=8\left(x^2+\frac{73x}{8}-\frac{35}{4}\right)$

so, we get

$f(x)=8x^2+73x-70$

How can variables and mayhem expressions be used to show different ways of a pattern?

earnstyle [38]

Answer:

A variable is a letter or symbol, such as a, b, or x, that represents a number. An algebraic expression is a combination of one or more variables; it may include numbers and operation signs. For example, 2 d 5 is an algebraic expression that could represent two times the figure number plus five.

ALGEBRA HELP PLZZZZZZZZZ

Elan Coil [88]

1st transformation:
$A'=(-3,-4)\\
B'=(-7,-4)\\
C'=(-3,-8)\\
D'=(-7,-8)$

2nd transformation:
When you rotate a point around the origin by 180 degrees, you change both coordinates to opposite values.
$A''=(3,4)\\ B''=(7,4)\\ C''=(3,8)\\ D''=(7,8)$
