Answer:-105
Step-by-step explanation:
Answer:
Ok so, let's break it down
Step-by-step explanation:
-35+(-31)
Let's ignore the parenthesis and the - symbol
35+31
That would equal 66, so now we add back the - symbol which will make it -66
So we already have -66, so now we have -66+(-39)
We do the same thing we did with -35+(-31)
So we have 66+39
That makes -105
So your answer is -105

What is (5,3) and (6,7) in point slope form
Answer:
4
Step-by-step explanation:
( x1, y1 ) = ( 5, 3 )
Here,
x1 = 5
y1 = 3
( x2, y2 ) = ( 6, 7 )
Here,
x2 = 6
y2 = 7
Formula : -
Slope = ( y2 - y1 ) / ( x2 - x1 )
Slope = ( 7 - 3 ) / ( 6 - 5 )
= 4 / 1
Slope = 4
Answer:
(y−3)=4(x−5)
Step-by-step explanation:
Point slope form is defined by the formula [tex]y-y_{1}=m(x-x_{1})[/tex]
First, you find the slope using the slope equation [tex]\frac{y_{2} -y_{1}}{x_{2}-x_{1}}[/tex]. (7−3)/(6−5)=4. Then you plug it back into the point slope form equation, and also plug in the points from y1 and x1.
This is also y=4x−17 in slope-intercept form or −4x+1y=−17 in standard form.
Find the equation for the horizontal line that goes through the point V(-5,17)
Answer:
x = -5
Step-by-step explanation:
x = -5 because a horizontal line does not change in y value
Horizontal line that goes through the point V(-5,17) is y=17.
The horizontal line that passing through any point (a,b) is y=b
And it has slope equals to zero.It is parallel to the x-axis in the coordinate plane.So the horizontal line passing through the point is y=17

Solve for slope-intercept
y + 2 = 1/2 (x - 4)
Answer:
y = ½x - 4
Step-by-step explanation:
Given the linear equation in point-slope form, y + 2 = ½(x - 4):
To transform the equation into its slope-intercept form, y = mx + b:
y + 2 = ½(x - 4)
Distribute ½ into the parenthesis:
y + 2 = ½x - 2
Subtract 2 from both sides:
y + 2 - 2 = ½x - 2 - 2
y = ½x - 4 ← This is the slope-intercept form.

Sam Snail is at the bottom of a pipe 30 feet deep. He can crawl three feet up each day, but each night he slides back two feet. How long will it take Sam to get to the surface?
Answer:
It will take 30 days to reach the top of the 30-foot deep pipe.
Step-by-step explanation:
Let's track Sam Snail's movement each day:
Day 1 -
0 + 3 - 2 = 1
Day 2 -
1 + 3 - 2 = 2
Day 3 -
2 + 3 - 2 = 3
Day 4 -
3 + 3 - 2 = 4
Day ...
We can see that the day always matches up with the height on the pipe. This means for the snail to have traveled 30 feet, he needs to have spent 30 days with a constant rate of movement.
Hope this helps!

Answer:
-42
Step-by-step explanation:
could someone help me with this question including a full explanation? thank you have a great day.
Step-by-step explanation:
just think about the basic formulas for area and perimeter of rectangles, and what pieces of information we already have directly.
area = length × width
perimeter = 2×length + 2×width = 136 m
=> length + width = 68 m
then we know
length = 2×width + 8
this we use as substitute in the simplified perimeter equation :
2×width + 8 + width = 68
3×width + 8 = 68
3×width = 60
width = 20 m
and therefore
length = 2×width + 8 = 2×20 + 8 = 40+8 = 48 m
and now we can calculate the area :
area = length×width = 48×20 = 960 m²
please consider that for a length or distance we use m (or other length units), for and area then m². for a volume then m³. as a basic unit for an area is a square. and for a volume a cube.
Jim's piano lessons are 30 minutes
longer than Suzanne's clarinet
lessons, Suzanne's clarinet lessons
are one-third the length of Pedro's
guitar lessons. If Pedro's guitar
lessons are 60 minutes long, how long
are Jim and Suzanne's lessons?
Answer:
Suzanne's lessons are 20 minutes long.
Jim's lessons are 50 minutes long.
Step-by-step explanation:
Jim's lessons = 30min longer than Suzanne's lessons
Suzanne's lessons = 1/3 of Pedro's lessons
Pedro's lessons = 60min
First, you need to find Suzanne's lesson time because her lessons are linked to Pedro's. Since you know Pedro's lesson is 60 minutes long and Suzanne's are a third of that you do: 60/3. Which is 20. So you know Suzanne's lessons are 20minutes long.
Next, since you know Suzanne's lessons are 20minutes long and Jims are 30mins longer than Suzanne's you do: 20+30. Which equals 50minutes. So, Jim's lessons are 50minutes long.
