It contains multiple points. If you’re looking specifically for a point plug the number that is on the x axis into the equation then solve for y.

Answer:

(0, -2) --> Y-Intercept

Step-by-step explanation:

y - 3 = -2( x + 1 )

y - 3 = -2x - 2

y= -2x -2

Y-Intercept = (0,y)

= (0, -2)

Suppose y = 2x + 1 , where x and y are functions of t. (a) if dx/dt = 3, find dy/dt when x = 4. dy dt = (b) if dy/dt = 2, find d
qwelly [4]

Answer:

Step-by-step explanation:

If y = 2x + 1, then dy/dt = 2(dx/dt).

If y = 2x + 1, then y = 2(40) + 1 when 40 is substituted for x.  y = 81.

(a) if dx/dt = 3, find dy/dt when x = 4:

       Replacing dx/dt with 3 in dy/dt = 2(dx/dt) yields dy/dt = 2(3) = 6.

(b) if dy/dt = 2, find dx/dt when x = 40:

        Replacing dy/dt with 2 in dy/dt = 2(dx/dt) results in 2 = 2(dx/dt), so dx/dt must be 1.

Solve for x in each of the equations or inequalities below, and name the property and/or properties used:
nordsb [41]

Answer

a) 3/4 x = 9

    x = \dfrac{9\times 4}{3}

    x = 12

b)  10+ 3x = 5x

     2 x = 10

        x = 5

c) a + x = b

       x = b - a

d) c x = d

      x =  \dfrac{d}{c}

e)  \dfrac{1}{2} x - g < m

     \dfrac{1}{2} x< m + g

              x  < 2( m + g)

f) q + 5 x = 7 x - r

   q + r = 2 x

      x = \dfrac{q + r}{2}

What is the distance between point G(−4, 1) and point H(−12, 1) ?
Naya [18.7K]

Answer:

8 units

Step-by-step explanation:

because they have the same y axis all we need to do is subtract the distance between the x axis to get the distance between the points
