4(2x + 3) = 5x + 3x - 6
Likurg_2 [28]

Answer:

No solution.

Step-by-step explanation:

4\left(2x+3\right)=5x+3x-6\\4\left(2x+3\right)=8x-6\\4\left(2x+3\right)\\(a=4,\:b=2x,\:c=3)\\=4\cdot \:2x+4\cdot \:3\\=8x+4\cdot \:3\\=8x+12\\8x+12=8x-6\\8x+12-12=8x-6-12\\0=-18

If the final answer is 0 and both sides of this equation are unbalanced, that means there will be no solution.

Based upon extensive data from a national high school educational testing program, the standard deviation of national test score
Amiraneli [1.4K]

Answer:

The standard error of the mean is 10.11 points

Step-by-step explanation:

Standard error of mean = t×sd/√n

sd = 115 points, n = 500, degree of freedom = n-1 = 500-1 = 499, assuming a 95% confidence level, t-value corresponding to 499 degrees of freedom and 95% confidence level is 1.96501

Standard error of mean = 1.96501×115/√500 = 10.11 points (to the nearest 100th)

write an equation in slope intercept form for the line that passes through the points (3,2) and(-9,6)
netineya [11]

Answer:

y = - \frac{1}{3} x + 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (3, 2) and (x₂, y₂ ) = (- 9, 6)

m = \frac{6-2}{-9-3} = \frac{4}{-12} = - \frac{1}{3}, hence

y = - \frac{1}{3} x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 9, 6), then

6 = 3 + c ⇒ c = 6 - 3 = 3

y = - \frac{1}{3} x + 3 ← in slope- intercept form
