Answer:

A=32

B=3

C=7

Step-by-step explanation:

Caitlyn surveyed 100 students to find out their favorite class. There were 29 students who enjoyed biology and 35 students who enjoyed English. There were 12 students who did not enjoy Biology, English, or Math.

29 like Biology so to find B you subtract. 29-6-5=3

35 like English so to find C 35-3-5-20=7

Total of 100 students subtract what you know to find A.

100-15-6-5-3-7-20-12=32

Answer:

x = 1

y = -1

Point = (1,-1)

Step-by-step explanation:

2x + 3y = -1 = y = -2/3 - 1/3

5x + 2(-2/3 - 1/3) = 3

5x - 1 1/3 - 2/3 = 3

5x - 2 = 3

+2 +2

5x = 5

x = 1

2(1) + 3y = -1

2 + 3y = -1

-2 -2

3y = -3

y = -1

Use the drop-down menus to complete the statements about the function p(x) = x(x – 1) + 1. The value of a is . The value of b is

Ludmilka [50]

Answer: The value of a is 1. The value of b is -1. The value of c is 1. The value of the discriminant is -3. The quadratic function will not intersects the x-axis.

Explanation:

The standard form of a quadratic equation is,

$p(x)=ax^2+bx+c$

The given function is,

$p(x)=x(x-1)+1$

It can be written as,

$p(x)=x^2-x+1$

By comparing this equation with the standard form of quadratic equation. we get,

$a=1$

$b=-1$

$c=1$

The formula for discriminant is,

$D=b^2-4ac$

$D=(-1)^2-4(1)(1)$

$D=1-4$

$D=-3$

The value of the discriminant is -3.

If D<0, it means the function have no real roots.

If D=0, it means function have one real roots.

If D>0, it means function have two real roots.

Since D<0 it means the function have no real roots. So the function will not intersect the x-axis at any point.

Answer:

$g(x)=x-1\\g(f(x))=(-2x-5)-1\\g(f(x)=-2x-6$

Step-by-step explanation:

So this is a composition of functions. Think back to solutions of equations. You would have to put the equation into the other equations. It's like this!

So I graphed it like this on desmos:

$g(x)=x-1\\g(f(x))=(-2x-5)-1\\g(f(x)=-2x-6$
