Answer:

Step-by-step explanation:

2y + 3y -6(y + 2) = -y + 6

Solving lik terms

5y - 6(y + 2) = - y + 6

5y - 6y - 12 = - y + 6

-y - 12 = - y + 6

Bringing like terms on one side

-12 - 6 = - y + y

-18 = y

The sum of the two digits of a number is 16. The number formed by reversing the digits is 18 more than the original number. Dete

nydimaria [60]

9u-9t=18

original no. is 10t+u
reversed no. is 10u+t

so its (10u+t)-(10t+u)=18
which gives 9u-9t=18

Which statement is true about the function f(x)= StartRoot negative x EndRoot?

UNO [17]

Answer:

The domain of the graph is all real numbers less than or equal to 0

Step-by-step explanation:

we have the function

$f(x)=\sqrt{-x}$

we know that

The radicand must be positive

$-x \geq 0$

Solve for x

Multiply by -1 both sides

$x\leq 0$

The domain is the interval ------> (-∞,0]

All real numbers less than or equal to zero

The range of the function is the interval -----> [0,∞)

$f(x)\geq 0$

see the attached figure to better understand the problem

All real numbers greater than or equal to zero

<em><u>Verify each statement</u></em>

case 1) The domain of the graph is all real numbers

The statement is false

Because, the domain is all real numbers less than or equal to zero

case 2) The range of the graph is all real numbers

The statement is false

Because, the range is all real numbers greater than or equal to zero

case 3) The domain of the graph is all real numbers less than or equal to 0

The statement is true

case 4) The range of the graph is all real numbers less than or equal to 0

The statement is false

Because, the range is all real numbers greater than or equal to zero

4)
3x-2y=10
5x+y=4

We solve this system of equation by elimination method.
3x-2y=10
2(5x+y=4)
------------------------
13x=18

Answer: A) 13x=18

5)
slope-intercept form:
y=mx+b
y=f(x)

m=slope
b=y-intercept

1) we calculate the slope:
we choose any two points of this table:
For example: (2,2) and (3,4)

Given two points (x₁,y₁) and (x₂,y₂) the slope of the line that passes through these points will be:
m=(y₂-y₁)/(x₂-x₁)
In this case:
m=(4-2)/(3-2)=2

2) we compute "b";
we choose an any point of this talbe:
For example: (4,6), and we substitute "x" for "4" and "y" for "6" in the next equation:
y=2x+b
6=2(4)+b
b=6-8
b=-2

3) we build the function that it belong this table:
m=2
b=-2
f(x)=mx+b
f(x)=2x-2

Answer: B) f(x)=2x-2
