Step-by-step explanation: Since the first one is the same model as the 2nd but with different letter and the order for the first one would be the same as the 2nd model.

Answer:

x=27

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5/3x-4/3x-1=8

5 /3 x+  −4 /3 x+−1=8

(5 /3 x+  −4 /3 x)+ (−1) =8 (Combine Like Terms)

1/3x-1 =8

1/3x=9

(1/3 x) x 3 = 3 x 9

x=27

Answer: x=27

Step-by-step explanation: if you want to Solve for X, you have to by simplify both sides of the equation, then isolating the variable.

Answer:

[tex]A(t)=250-230e^{-\frac{t}{50} }[/tex]

Step-by-step explanation:

A(t) is the amount of salt in the tank at time t.

dA / dt = rate of salt flowing into the tank - rate of salt going out of the tank

dA / dt = (1 g/L)*(5 L/min) - (A(t)/250 g/L) * (5L/min)

dA / dt = 5 g/min - (A(t) / 50) g/min

[tex]\frac{dA}{dt}+\frac{A(t)}{50} = 5\\\\The\ integrating\ factor(IF)= e^{\int\limits \frac{1}{50}dt }=e^{\frac{t}{50} }\\\\Multiplying\ through\ by\ the\ I.F:\\\\\frac{dA}{dt}*e^{\frac{t}{50} }+\frac{A(t)}{50}*e^{\frac{t}{50} } = 5*e^{\frac{t}{50} }\\\\Integrating \ both \ sides:\\\\\int\limits[ \frac{dA}{dt}*e^{\frac{t}{50} }+\frac{A(t)}{50}*e^{\frac{t}{50} }] dt=\int\limits 5e^{\frac{t}{50} } dt\\\\A(t)e^{\frac{t}{50} } =\int\limits 5e^{\frac{t}{50} } dt\\\\[/tex]

[tex]A(t)e^{\frac{t}{50} } =250e^{\frac{t}{50} }+C\\\\A(t)=250+Ce^{-\frac{t}{50} }\\\\But\ A(0) = 20\\\\20=250+Ce^{-\frac{0}{50} }\\\\C+250=20\\\\C=-230\\\\A(t)=250-230e^{-\frac{t}{50} }[/tex]

Answer:

d, 40% !

Step-by-step explanation:

this one, you can use long division ! since the faction of apple to all fruit is 6/15, you divide 6 by 15. you would get the decimal 0.4

in order to make that a percentage, you'd just move the decimal two places to the right, then add a % !! so it's 40% !!

i really hope this helped!

Answer: Choice B)  -infinity < x < infinity

==========================================================

Explanation:

The parabola goes on forever to the left and to the right. We can plug in any x value without worrying about something as a division by zero error. So any real number will work.

Writing -infinity < x < infinity refers to the entire number line, which is the set of all real numbers.

yeah it's counting method

The rectangular equation that represents the parametric equation [tex]x=t^{\frac{1}{2} }[/tex] and y = 4t is:

[tex]y=4x^2[/tex] for [tex]x\geq0[/tex]

Note the given representations:

[tex]x=t^{\frac{1}{2} }[/tex]

[tex]y=4t[/tex]

Make t the subject of the formula from the expression [tex]x=t^{\frac{1}{2} }[/tex]

[tex]x^2=t^{\frac{1}{2}\times2\\\\x^2=t\\t=x^2[/tex]

Substitute [tex]t=x^2[/tex] into y = 4t

[tex]y=4x^2[/tex]

Therefore, the rectangular equation that represents the parametric equation [tex]x=t^{\frac{1}{2} }[/tex] and y = 4t is:

[tex]y=4x^2[/tex] for [tex]x\geq0[/tex]

Answer:

R = 0.8815 ;

y = 6.14679X + 2.33028 ;

14.624

Step-by-step explanation:

Using an online correlation Coefficient calculator, the correlation Coefficient, R between the number of lawn fertilizer sold and the number of lawn mowers sold is 0.8815. This R value depicts a strong positive correlation between both variables.

The regression line equation obtained by Plotting the values to generate a linear model is :

y = 6.147X + 2.330

With ;

Slope or gradient being 6.147

Intercept = 2.330

C.)

x = 2

y = 6.147X + 2.330

y = 6.147(2) + 2.330

y = 14.624

Answer:

y=3/4x+1/2

Step-by-step explanation:

slope intercept form: y=mx+b

find the slope with y2-y1/x2-x1: (-4-5)/(-6-6)= 3/4

substitute one of the coordinates in the equation with the slope: 5=3/4(6)+b

solve to find b:

b=1/2

substitute in the equation:

y=3/4x+1/2
