Answer:
The equation for the world problem is
p-(-9)=12 or -9-p = 12
Answer:
The ladder will go approximately 35.71 ft up the building.
Step-by-step explanation:
The 50 ft ladder is leaning against a building and the base of the ladder is 35 feet from the base of the building.
It means the ladder will form a right triangle with the building with the following dimensions:
Using the Pythagorean Theorem to determine the height,
Here,
Substitute the given values into the equation to determine the height:
We know that height can not be negative. Thus,
ft
Therefore, the ladder will go approximately 35.71 ft up the building.
Answer:
the son is 30 and the daughter is 15
Step-by-step explanation:
the mom is 55 in 15 years
100-55=45
45-30=15
15x2=30
Answer:
D. The scale factor is 1:840
Step-by-step explanation:
Make 630 ft into inches, so 7560
Then make it 9/7560, which simplifies to 1/840
Point-slope form is a different type of way to write a linear equation than slope-intercept (y=mx+b). Point-slope is in this form: y-ypoint=m(x-xpoint)
Point-slope uses a point and the slope (namesake) to make an equation and can be converted to slope-intercept form. For example, if (4, 2) is my point and 2 is my slope, then point-slope form would be y-2=2(x-4). (This can then be solved for y to get slope-intercept)
Remember to use the same point when plugging in for your x and y in the equation, never use two different points.
