factor 144abc−108ab . if the expression cannot be factored, write cannot be factored.
Answers
The factored form of the expression 144abc - 108ab is 36ab(4c - 3).
To factor the expression 144abc - 108ab, we can first identify the common factors of the terms.
In this case, we can see that both terms have a common factor of 36ab:
144abc - 108ab = 36ab(4c - 3)
So, the expression can be factored as 36ab(4c - 3).
This means that the expression is not prime and can be simplified further by factoring out the common factor.
By factoring out the common factor of 36ab, we obtain the simplified form of the expression as 36ab times the binomial (4c - 3).

Answers
The solution of the system is (- 3, 8).
A system of linear equations is given by two tables. The first table is represented by the equation y = - 1/3x + 7, while the second table is not represented by any equation.
However, we can determine the equation of the second table by finding the slope of the line that passes through the points (0, 5) and (3, 6).slope = change in y/change in x= (6 - 5)/(3 - 0)= 1/3
Since the slope of the line is 1/3 and it passes through the point (0, 5), we can use point-slope form to find the equation of the line. Using point-slope form,
the equation of the second table is:y - 5 = 1/3(x - 0)y = 1/3x + 5To solve the system of equations, we can use substitution. We can substitute y = - 1/3x + 7 into the equation y = x + 5:y = x + 5- 1/3x + 7 = x + 5- 1/3x = - 2x = 6x = - 3
The solution for x is x = - 3. We can use this value to find the solution for y by substituting into either of the equations. Using y = - 1/3x + 7, we get:y = - 1/3(- 3) + 7= 1 + 7= 8

What is the impact of an increase in government spending on GDP and the rate of of interest? 6. What is the impact on national savings and the government budget balance of this increase?
Answers
To answer your questions, we need to analyze the given equations and variables:
Equation 1: C = 900 - 50T
Equation 2: Y = 400
Equation 3: (M/P) = 0.25 - 62.5r
Equation 4: (M/P) = 400
The equation of the IS curve represents the equilibrium relationship between real GDP (Y) and the real interest rate (r). From Equation 2, we can see that the equation of the IS curve is Y = 400.
The equation of the LM curve represents the equilibrium relationship between the real interest rate (r) and the level of real money supply (M/P). From Equations 3 and 4, we can equate the expressions for (M/P) and solve for r:
0.25 - 62.5r = 400
-62.5r = 400 - 0.25
-62.5r = 399.75
r ≈ -6.396
Therefore, the equation of the LM curve is r ≈ -6.396.
To find the equilibrium values of the real interest rate (r) and real GDP (Y), we need to find the point where the IS curve intersects the LM curve. From Equation 2, we already know that Y = 400. Substituting this into the equation of the LM curve, we can solve for r:
400 = -6.396
Therefore, the equilibrium values of the real interest rate and real GDP are r ≈ -6.396 and Y = 400.
The Keynesian multiplier represents the impact of changes in autonomous spending on the overall change in equilibrium output (GDP). In this case, we don't have information about autonomous spending (investment), so we can't calculate the Keynesian multiplier.
An increase in government spending (G) would shift the IS curve to the right. This would lead to an increase in GDP (Y) and potentially a decrease in the real interest rate (r) as the IS and LM curves intersect at a higher level of output. However, without more information about the magnitude of the increase in government spending, we cannot determine the exact impact on GDP and the rate of interest.
The impact on national savings and the government budget balance of the increase in government spending depends on the financing of the spending increase. If the government increases taxes (T) or borrows to finance the higher spending, it may impact national savings and the government budget balance. However, based on the given equations, we do not have sufficient information to determine the specific impact on these variables.

How many miles can be driven if you have at most $100 to spend on truck rental.

The charge for the rental truck can be represented by the equation: y= 0.28m+80
m is the miles driven
y is the total cost
Plug in 100 for y because that’s how much you have to spend
100=0.28m+80
-80 -80

Write the equation of the line with a slope of 34 and a y-intercept of −7 in Slope-Intercept and Point-Slope Form.
Answers
Y=34x+(-7) tho this is in y=Mx+b form so I hope this helps
The linear equation of the line is y = 34x - 7 and y + 7 = 34(x - 0)
How to determine the line equation?The slope is given as:
m = 34
The y-intercept is given as:
c = -7
A linear equation in slope intercept form is represented as:
y = mx + c
So, we have:
y = 34x - 7
The equation in point slope form is calculated as follows:
y = 34x - 7
Add 7 to both sides
y + 7 = 34x
Express 34x as 34(x)
y + 7 = 34(x)
Subtract 0 from x
y + 7 = 34(x - 0)
Hence, the linear equation of the line is y = 34x - 7 and y + 7 = 34(x - 0)
