What is the domain of the function y = -4x+1 if the range is -11
a_sh-v [17]

The range of a function is the set of all values that it can take when its independent variable takes values on the domain.

On the other hand, the range of a function is the domain of its inverse function, if that inverse exists, and vice-versa: the domain of a function is the range of its inverse function, if that inverse exists.

In the case of the given equation:

y=-4x+1

The inverse function exists since the function is linear, and it can be found by isolating <em>x</em>:

x=-\frac{1}{4}(y-1)

If the range of the original function is the set given by the number {

Jessica was given the area and the length of the base of a triangle. A = 17.5 units, b = 5 units. She solved the formula for are
pychu [463]

Answer:

She messed up the equation, A= B x h, she changed it midway, and also, you need to add the one half to make the equation valid

Step-by-step explanation:

A=1/2 x b xh

17.5 = 1/2 x 5 x h

35=5h     (multiply both sides by 2 to get rid of one half)

35/5 = 5h/5

7=h

The height of the triangle is 7 units

Please mark me brainliest, it really helps!

Three times the sum of a number and seven is two less than five times the number.
m_a_m_a [10]
3 (x + 7) =  5x - 2
3x + 21 = 5x - 2
3x - 5x = -2 - 21

-2x = -23 
x = -23/-2
x = 23/2
