Answer:

q=4/3

Step-by-step explanation:

simplify the right side, to 5/3

5/4q=5/3

multiply 4/5 on both sides

q = 5/3*4/5

q = 4/3

jek_recluse [69]

Answer:

There are no true solutions to the equation

Step-by-step explanation:

The equation is

y+1=√-2y-3

Find y

Square both sides

(y+1)^2=(√-2y-3)^2

y^2+2y+1= -2y-3

y^2+2y+1+2y+3=0

y^2+4y+4=0

Solve quadratic equation by factorisation

we have

(y+2)(y+2)=0

y=-2

Check

y+1=√-2y-3

-2+1=√-2(-2)-3

-1=√4-3

-1=√1

-1=1

This is not true

Math problem help me
Ratling [72]

Answer:

y=3x+2

Step-by-step explanation:

To find the equation, use the slope-intercept formula:

y=mx+b

m is the slope and b is the y-intercept. Now, it'll really help to draw a line through the points, connecting them. If you look at point (0,2), we can see that this is the y-intercept (where a point sits on the y-axis when x=0). You can insert this into the equation by taking the y value:

(0,2)\\y=mx+2

Now, take any two points to find the slope. To make it easier, I'll use (1,5) and (0,2). Use the slope formula for when you know two points:

\frac{y(2)-y(1)}{x(2)-(x1)} =\frac{rise}{run}

Rise over run is the change in the y-axis over the change in the x-axis. Insert values:

(1(x1),5(y1))\\(0(x2),2(y2))\\\\\frac{2-5}{0-1}

Solve:

\frac{2-5}{0-1}=\frac{-3}{-1}

Since both are negative, the result is a positive:

\frac{-3}{-1}=\frac{3}{1} =3

Insert this into the equation as m, the slope:

y=3x+2

Done.
