Find the values of a and b that make the quadrilateral a parallelogram.

Mathematics
1 answer:
Yuri [45]2 years ago
5 0

Step-by-step explanation:

both halves of a diagonal must be equal.

so,

8b - 30 = 6b + 6

2b = 36

b = 18

and

9a - 13 = 5a + 5

4a = 18

a = 18/4 = 4.5

What is the slope and y-intercept of the line 3x - 4y = 12?*
Lorico [155]

Answer:

m = 3/4; b = -3    

Step-by-step explanation:

1) First, put the given equation into slope-intercept form. This is so we can identify its slope and y-intercept easily. Isolate y:

3x-4y = 12\\-4y = -3x+12\\y = \frac{3}{4} x-3

2) Lines that are in slope-intercept form are represented by the formula y = mx + b. The number in place of m, or the coefficient of the x-term, represents the slope. The number in place of b represents the y-intercept. So, the slope of  y = \frac{3}{4} x-3  is \frac{3}{4}, and its y-intercept is -3.

At the end of 10 basketball games, a teams mean score is 35 points per game. At the end of 11 games, their mean score has gone d
morpeh [17]

Their total points for the first 10 games were

(10) x (35) = 350 total .

Their total points after 11 games were

(11) x (33) = 363 total .

They must have scored (363 - 350) = 13 points in that 11th game.

I hate to say it, but these kids and their coach are in the wrong game.
