What is the equation of the line in point-slope form and slope-intercept form that is
perpendicular to the line
4x - 3y = 30 and passes through the point (-8, 7)?
9514 1404 393
Answer:
y -7 = -3/4(x +8)y = -3/4x +1Step-by-step explanation:
The slope of a line in the form ...
ax +by = c
is ...
m = -a/b
So, the slope of the given line is ...
-4/(-3) = 4/3
The slope of the perpendicular line is the opposite reciprocal of this,
m' = -1/(4/3) = -3/4
__
The point-slope equation of a line is ...
y -k = m(x -h) . . . . . . . . line with slope m through point (h, k)
Then your perpendicular line with slope -3/4 through point (-8, 7) is ...
y -7 = -3/4(x +8)
Rearranging to slope-intercept form, we get ...
y = -3/4x -3/4(8) +7
y = -3/4x +1

You have a trailer with the following dimensions. Height 125cm. Length 2.4m. Width 1.65m. How much cub sand will you be able to load?
Answer:
18.75m³ of sand
Step-by-step explanation:
volume =lbh
h=125cm=1.25m
v=2.4*6.25*1.25
=18.75m³
The cub sand will be able to load 4.95m³.
To solve this question, we've to find the volume of the trailer and this goes thus:
Height = 125cm = 1.25m
Length = 2.4m.
Width = 1.65m
Volume = Length × Width × Height
Volume = 2.4m × 1.65m × 1.25m
Volume = 4.95m³
Therefore, the cub sand will be able to load 4.95m³.

A piece of wire 100 cm long is cut into two pieces, each to be bent to make a square. The length of a side of one square is to be 4 cm longer than the length of a side of the other. How should the wire be cut?
Answer:
The two pieces will be 42 and 58 cms long.
Step-by-step explanation:
Let the length of the smallest square be x cm.
Then the length of the other will be x + 4 cm
So, as there are 4 sides in a square, we have the equation:
4x + 4(x + 4) = 100
8x + 16 = 100
8x = 84
x = 10.5 cm.
So we need 4*10.5 = 42 cms for one square and 4 * 14.5 = 58 cms for th other square.

The length of a rectangle is 3 times its width. The perimeter is 39. Find the length and width of the rectangle.
Answer:
Let width of rectangle be x cm.
3x+x+3x+x=39
8x=39
x=39÷8
=39/8
=4/7/8
3x=39/8×3
=117/8
=14/5/8
Hence, length=14/5/8cm while width=4/7/8cm.

The value of the expression is 1.Demichael orders a set of numbers on his
homework. In descending order, the first
number is 5 1/2 and the last number is 5 1/3
Which of the following numbers is NOT in
Demichael's list?
A V25
B 5.45
C 5 12 름
D 5.34
The numbers are ordered, such that the first number (the largest one) is:
(5 + 1/2)
And the last number (the smaller one) is (5 + 1/3). Only by knowing this, we will see that the correct options are A and C.
We want to see which of the following numbers is not on the list:
A) √25
B) 5.45
C) 5 12
D) 5.34
One of these numbers can only be in the list if it is larger than (5 + 1/3) and smaller than (5 + 1/2).
To see this easier, let´s rewrite both of these:
5 + 1/2 = 5 + 0.5 = 5.5
5 + 1/3 = 5 + 0.33 = 5.33
Then if a number is smaller than 5.33, the number can't be in the list.
Here we can see two numbers that are smaller than 5.33
These are:
Option A) √25 = 5 < 5.33
Option C) 5.12 < 5.33
And there is no number larger than 5.5
Concluding, the numbers that are not in Demichael's list are:
√25 and 5.12

On a number line what is the distance between -3/2 and 6?
Answer:
7.5 unitsStep-by-step explanation:
The distance is always positive and is same as the absolute value of subtraction of the two numbers on the line.
This can be shown as:
|-3/2 - 6| = |-1.5 - 6| =|-7.5| = 7.5or
| 6 - (-3/2)| = |6 + 1.5| = |7.5| = 7.5Answer:
15/2 or 7.5
Step-by-step explanation:
Distance = x_2 - x_1
Distance = 6 - (-3)/2
Distance = 6 + 3/2
Distance = 12 + 3/2
Distance = 15/2 or 7.5
