Answer:
-50
Step-by-step explanation:
2/5(j + 40) = -4
j+40 = -4 ÷2/5
j+40 = -10
j = -10 - 40
j = -50

The lengths of the two diagonals of a rhombus are 6 cm and 8 cm. Find the length of its perimeter (in
cm)
Answer:
The perimeter of the rhombus is 20 cm
Step-by-step explanation:
Perimeter of a Rhombus
Given the lengths of the two diagonals of a rhombus, let's call them a and b, the perimeter of the rhombus is given by:
[tex]P=2\sqrt{a^2+b^2}[/tex]
The values of the diagonals provided by the question are a=6 cm, b=8 cm, thus the perimeter is:
[tex]P=2\sqrt{6^2+8^2}[/tex]
[tex]P=2\sqrt{36+64}[/tex]
[tex]P=2\sqrt{100}=2*10[/tex]
[tex]P=20\ cm[/tex]
The perimeter of the rhombus is 20 cm

Step-by-step explanation:
Write an equation of the line that passes through (2,−5) and is parallel to the line 2y=3x+10
Step-by-step explanation:
Divide two on both sides to get rid of it and the make the equation in the form y = mx + c
[tex] \frac{2}{2} y = \frac{3}{2} x + \frac{10}{2} [/tex]
y = 3/2x + 5
since both lines are parallel they must have the same gradient which is 3/2
y = 3/2x + c
All you have to do now is to replace x and y with (2, -5) to find c
x = 2
y = -5
-5 = 3/2 × 2 + c
-5 = 3 + c
c = -5-3
c = -8
[tex]y = \frac{3}{2} x - 8[/tex]

Answer:
K= 18
Step-by-step explanation:
1 and 8 are exact opposites so they equal eachother
so
3k-7=5k+29
subtract 3k to 5k and add 7 to 29
2k=36
then divide 36 by -2
so K = 18

Which of these equations represents the line that passes through point N and is perpendicular to the line passing through points O and M?
y = x + 3
y = x - 3
y = -x + 3
y = -x - 3
Answer:
i think its c
Step-by-step explanation:
The equation of a straight line is represented as: [tex]y = mx + c[/tex]
The equation of the line is: [tex](c)\ y = -x +3[/tex]
The coordinates are given as:
[tex]M = (-5,5)[/tex]
[tex]N = (5,-2)[/tex]
[tex]O = (-8,2)[/tex]
First, we calculate the slope of line MO using:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, we have:
[tex]m = \frac{2-5}{-8--5}[/tex]
[tex]m = \frac{-3}{-3}[/tex]
[tex]m = 1[/tex]
The line that passes through N is perpendicular to MO.
This means that, the slope (m2) of the line is:
[tex]m_2 = -\frac 1m[/tex]
So, we have:
[tex]m_2 = -\frac 1{1}[/tex]
[tex]m_2 = -1[/tex]
The equation of the line is then calculated as:
[tex]y = m_2(x - x_1) + y_1[/tex]
Where:
[tex]m_2 = -1[/tex]
[tex]N = (5,-2)[/tex] --- [tex](x_1,y_1)[/tex]
So, we have:
[tex]y = -1(x -5) - 2[/tex]
[tex]y = -x +5 - 2[/tex]
[tex]y = -x +3[/tex]
Hence, the equation of the line is: [tex](c)\ y = -x +3[/tex]

Evi’s watch is water-resistant up to -15 feet. Mateo’s watch is water-resistant up to 8 times the depth of Evi’s watch. Mateo’s watch is water-resistant to what maximum depth?
Answer:
-120 feet
Step-by-step explanation:
Evi's is -15 feet, and Mateo's is 8 times that, so you multiply -15 by 8, and get -120 feet

Answer:
[tex]\boxed {x = \frac{8}{3}}[/tex]
Step-by-step explanation:
Solve for the value of [tex]x[/tex]:
[tex]x - \frac{17}{3} = -3[/tex]
-Add both sides by [tex]\frac{17}{3}[/tex] and convert [tex]-3[/tex] to a fraction [tex]-\frac{9}{3}[/tex]:
[tex]x - \frac{17}{3} + \frac{17}{3} = -3 + \frac{17}{3}[/tex]
[tex]x = -\frac{9}{3} + \frac{17}{3}[/tex]
-Since both [tex]-\frac{9}{3}[/tex] and [tex]\frac{17}{3}[/tex] have the same denominator, then you would add the numerators:
[tex]x = \frac{-9 + 17}{3}[/tex]
[tex]\boxed {x = \frac{8}{3}}[/tex]
Therefore, the value of [tex]x[/tex] is [tex]\frac{8}{3}[/tex].

If the side lengths of a Triangle are: 2t, t, 3t, and the perimeter is equal to 60 meters; what is the value of t? a 20 b 12 c 10 d 6
Answer:
x equals 10
Step-by-step explanation:
so so you if the perimeter is 60 and when you measure perimeter you add up all these sides so you would add 2t + t + 3t = 60 then you would divide by 6 and get 10.
Use the Pythagorean Theorem to find the missing length. Round your answer to the
nearest tenth.
In this triangle it is clear that the unknown side x is the hypotenuse of both the triangles that are being formed . So , let us take any one of the triangles and with it's length let us find the length of their hypotenuse which is side x .
= 5² + 5² = x² ( according to the pythagorean theorem the square on the hypotenuse will be equal to the sum of the squares on the other two legs )
= 25 + 25 = x²
= 50 = x²
= 7.0710678119 = x
But they have given that we have to round it off to the nearest tenths , so ;
= 7.0710678119 will be equal to = 7.10
= 7.1 = x
Therefore , the length of the unknown side x = 7.1 .

Answer:
4.5 is the range
Step-by-step explanation:
Ok, so it's asking for range, Range means The Highest number minus the smallest number.
What is the highest number? it's "2.3"
What is the lowest number? it's "-2.2"
so subtract those numbers and you get your answer!
Wait... why is the range 4.5? well, you do 2.3-(-2.2) when there are 2 minuses, you switch it to a + sign. so, 2.3+2.2=4.5!
