Answer:

y = -3/2x + 2

Step-by-step explanation:

The equation has the format y = mx + b where m is the slope and b is the y-intercept.

The question gives you the y-intercept, so b = 2.

As for the slope, you need the fact that perpendicular lines have slopes that are opposite ("negative") reciprocals of each other.

The slope of the line given in the question is 2/3. The opposite reciprocal of 2/3 is - 3/2.

The equation for the line is y = -3/2x + 2

Find all values of x that make the triangles congruent. Explain your reasoning.

Answer:

x = $\frac{4}{5},5$

Step-by-step explanation:

If both the triangles ΔABC and ΔBCD are congruent,

Corresponding sides of both the triangles will be proportional.

$\frac{AB}{BD}=\frac{AC}{CD}$

$\frac{5x}{3x+10}=\frac{5x-2}{4x+3}$

5x(4x + 3) = (5x - 2)(3x + 10)

20x² + 15x = 15x² + 50x - 6x - 20

20x² + 15x = 15x² + 44x - 20

20x² - 15x² = 44x - 15x - 20

5x² = 29x - 20

5x² - 29x + 20 = 0

5x² - 25x - 4x + 20 = 0

5x(x - 5) - 4(x - 5) = 0

(5x - 4)(x - 5) = 0

$x=\frac{4}{5},5$

PLEASE HELP 25PT

Bess [88]

Hi

1.If Mrs.Walters drives 360 miles on 25 gallons of gas , she drives 14.4 miles on 1 gallon of gas .

Work; I made a proportion , but you can just divide 360 and 25 .
x=14.4 miles

If Mr.Walters drives 480 miles on 32 gallons of gas , he drives 15.06 miles on 1 gallon of gas .
x=15.06 miles
2. Mr.Walter because he drives more miles with a gallon .
Work; 15.06 miles is greater than 14.4 miles.

Hope it helps and have a wonderful day.

Write the equation log216 36=36 in logarithmic form

Zielflug [23.3K]

This is impossible and it is not even an equation since $\log_{216} 36 = 2/3$
