Find what the measurements of angles a-d are and state the reason <br><br> Like how do you solve it?
ANTONII [103]
Angle d is a vertical angle to the 70° angle meaning that angle d is 70°--to confirm it, line EF is 180° and
180- 40-70= 70° (and 70/2 is 35 which is the measurement for angle e and f bc we know that they are equal)

To find a-- we know now that f is 35, bc a and f are vertical angles, that means a is equal to f...

ANSWER- a is 35° and d is 70°

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

so

-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

Answer:

$ 2000

Step-by-step explanation:

Find the equation. You find the gradient by using the gradient formula (rise/run)

that would be

1600 - 800 over 40 - 20

800/20

m (gradient) = 40

Hence 40x ...
