Answer:

1. 112

2. 46

Step-by-step explanation:

When two parallel lines are intersected by a transversal, the alternate interior angles are supplementary. Meaning that their angle measures add up to 180 degrees. Set up an equation and solve for the unknown angle using inverse operations.

$68 + ? = 180\\-68\\\\? = 112$

When two parallel lines are intersected by a transversal, the corresponding angles are congruent, in other words, they have the same angle measure.

$? = 46$

1) a^2+2ab+b^2=25, find a+b

Pavel [41]

Answer:

1) -5 and +5; 2) -9 and +9

Step-by-step explanation:

1) a² + 2ab + b² = 25

(a + b)² = 25 Wrote the left-hand side as a square

a + b = ±5 Took the square root of each side

All values of a + b are -5 and +5.

2) a² − 8ab + 16b² = 81

(a - 4b)² = 81 Wrote the left-hand side as a square

a - 4b = ±9 Took the square root of each side

All values of a - 4b are -9 and +9.

What is the y-intercept of a line that has a slope of 3 and passes through point (-1, -7)?

Ivanshal [37]

Answer:

-4

Step-by-step explanation:

We know it's a linear equation and the slope is a whole number. Using point slope form we will write the equation:

y - y1 = m (x - x1) in which y1 is -7, m is 3, and x1 is -1

y - (-7) = 3(x-(-1))

y+7 = 3(x+1)

y+7 = 3x +3

Change to slope-intercept form:

y = 3x + 3 - 7

y = 3x = -4

the y intercept is -4

Two rectangular swimming pools measure 16 feet wide by 24 feet long. The first pool is 3 feet deep. the second pool is 5 feet de

vodomira [7]

Answer:

768 cubic feet

Step-by-step explanation:

16 * 24 = 384

384 * 3 for the depth of the first pool = 1152

384*5 for depth of second pool = 1920

1920-1152 = 768
