3x 32 = 7x + 28

Answers

Answer 1

Answer:

x= 28 /89

Step-by-step explanation:

3x(32)=7x+28

Step 1: Simplify both sides of the equation.

96x=7x+28

Step 2: Subtract 7 from both sides.

96x   7x+28

−7             −7

89x=28

Step 3: Divide both sides by 89.

89x /89 = 28 /89

This is not a function. This is because if there are any repeating x values (the first values of each set) it is not a function. It is okay for there to be repeating y values (the second values of each set) but not x values.

Are these lines parallel, perpendicular, or neither? 3y=x+4 and 3x+y=1

Answers

Answer:

perpendicular

Step-by-step explanation:

3y = x + 4 in slope intercept form y = 1/3x +4/3

3x + y = 1 in slope intercept form y = -3x +1

the slopes are negative reciprocals of each other so they are perpendicular

Answer:

These lines are perpendicular

Step-by-step explanation:

3y=x+4

 [tex]y = \frac{1}{3}x+\frac{4}{3}[/tex]

Slope (m1) = 1/3

3x+y=1

     y = -3x + 1

Slope (m2) = - 3

m1 * m2 = [tex]\frac{1}{3}* -3[/tex]

             = -1

So, these lines are perpendicular.

If product of two slopes is (-1), then they are perpendicular lines.

If both lines have same slope, then they are parallel.

Property of an isosceles triangle,

Opposite angles of the equal sides in an isosceles triangle are equal in measure.

m∠D = m∠F

(2x + 8) = (3x + 4)

3x - 2x = 8 - 4

x = 4

m∠D = m∠F = (3×4 + 4)°

                    = 16°

m∠D = m∠F = 16°

Since, sum of interior angles of a triangle = 180°

m∠D + m∠E + m∠F = 180°

16° + m∠E + 16° = 180°

m∠E = 180° - 32°

m∠E = 148°

Penny Weights, use the weights of the post 1983 pennies to construct a 98% confidence interval estimate of the standard deviation of the weights of all post-1983 pennies. S=0.0165 n=37. Find confidence interval. a. 0.01231 < Ï < 0.2111 b. 0.01239 < Ï < 0.02111 c. 0.1391 < Ï < 0.2311 d. 0.001219 < Ï < 0.002111

Answers

Answer:

c. 0.1391 < Ï < 0.2311

Step-by-step explanation:

The formula for Confidence Interval is given as:

Mean ± z × Standard deviation/√n

Z score for 98% confidence interval = 2.326

Mean = Significance level = 100% - 98%

= 2% = 0.02

Standard deviation = S=0.0165

n= 37

Hence,

Confidence Interval =

0.02 ± 2.326 × 0.0165/√37

0.02 ± 0.0063094687

Confidence Interval

0.02 - 0.0063094687

= 0.1391

0.02 ± 0.0063094687

= 0.2311

Hence, the Confidence Interval = (0.1391, 0.2311)

= c. 0.1391 < Ï < 0.2311

D) is the correct answer. angle D is greatest because it’s across from the greatest value in the triangle, etc

Answer:

G > F > H

Step-by-step explanation:

In a triangle, the largest side and largest angle are opposite eachother.   Similarly, the smallest side and smallest angle are opposite eachother.

We have 3 sides of length 6 cm, 11 cm, and 12 cm.  The angle opposite the 6 cm side is the smallest (H).  The angle opposite the 14 cm side is the largest (G).
