The graph shows the solution to the initial value problem y'(t)=mt, y(t0)= -4
Charra [1.4K]
y'(t)=mt
\\
\\ y=\int {mt} \, dt=m \int{t} \,dt=m \frac{t^2}{2} +C \\ \\y= \frac{mt^2}{2}+C

Now find equation of the graph. It passes through the point (2,3), and intersects y-axis at -2.

y=at^2+b
\\
\\3=a\times 2^2-2
\\
\\3=4a-2
\\
\\5=4a
\\
\\a= \frac{5}{4} 
\\
\\y=\frac{5}{4} t^2-2 \\ \\y= \frac{m}{2} t^2+C
\\ \\  \frac{m}{2} = \frac{5}{4} 
\\
\\m= \frac{5}{2} 
\\
\\C=-2
\\
\\y(t_0)=-4
\\
\\-4= \frac{5}{4} t_0^2-2
\\
\\ -2= \frac{5}{4} t_0^2
\\
\\ t_0^2=- \frac{8}{5} 
\\
\\t_0=\pm \sqrt{- \frac{8}{5} }

Plz help me thanks so muchhhhh

Hi there.

The answer is (-2,7). The second choice.

Explanation:

We can use the graph method or the solving method.

For the graph method, find where both graphs intercept and that is x = - 2 y = 7.

But if you don't use the graph method. We can solve the equation.

y = 0.5x+ 8 \\ y =  \frac{5}{10} x + 8 \\ y =  \frac{1}{2} x + 8

Convert the expressions in simplified form.

Then combine both equations.

\frac{1}{2}x + 8 = 5 - x

Because there is the denominator. We get rid of it.

Multiply the whole equation by 2.

\frac{1}{2} x(2) + 8(2) = 5(2) - x(2) \\ x + 16 = 10 - 2x \\ 3x = 10 - 16 \\ 3x =  - 6 \\ x =  - 2

Since it is the two variables linear equations, we need to find y-value too.

Substitute x = -2 in any given equations.

I will substitute x = -2 in y = 5-x

y = 5 - x \\

Substitute x = -2 in the equation.

y = 5 - ( - 2) \\ y = 5 + 2 \\ y = 7

Thus, the answer is x = -2, y = 7

Or

(-2,7)
