Step-by-step explanation:
19 and 32
Answer:
the two numbers are 19 and 32
Step-by-step explanation:
let's call the numbers x and y.
write out the equations
x + y = 51
x - y = 13
simplify the second equation
x = 13 + y
substitute into the first equation and simplify
(13 + y) + y = 51
13 + 2y = 51
2y = 51 - 13
2y = 38
y = 19
substitute y for 19 in the second equation
x = 13 + y
x = 13 + 19
x = 32
translate into algebraic expression four divided by the sum of x and three
[tex]\frac{4}{x+3}[/tex]
sum is addition

[tex]\left[\begin{array}{ccc}-4&26 &-5 \\6&17&-8\\\end{array}\right][/tex] is the sum of the given matrices.
What is matrices?There are columns and rows in a matrix. The dimensions or size of a matrix are determined by these rows and columns. There are many different kinds of matrices, including row, column, null, square, diagonal, upper triangular, lower triangular, symmetric, and antisymmetric matrices.
Given two matrices,
[tex]\left[\begin{array}{ccc}4&19&-5\\7&0&-14\\\end{array}\right][/tex] and [tex]\left[\begin{array}{ccc}-8&7&-0\\-1&17&6\\\end{array}\right][/tex]
We need to find the sum of this given matrices
The only matrices that may be added together are ones of the same size. As a result, you can only add matrices if they are both m × n. For example, you can add two or more 3 × 3, 1 × 2, or 5 × 4 matrices. You cannot add a 2 × 3 and a 3 × 2 matrix, a 4 × 4 and a 3 × 3, etc. The number of rows and columns of all the matrices being added must exactly match.
thus,
Sum of matrices = [tex]\left[\begin{array}{ccc}4 -8&19 +7 &-5 + 0\\7 -1&0 + 17&-14 +6\\\end{array}\right][/tex]
Sum of matrices = [tex]\left[\begin{array}{ccc}-4&26 &-5 \\6&17&-8\\\end{array}\right][/tex]
Therefore, option D is correct.

Consider a force F = 〈–1, 3〉 applied to an object that is moving from the point (3, –9) to the origin.
Find the displacement vector of the object.
d = 〈 _,_ 〉
Find the work done in moving the object.
W = ___ Joules
Answer:
-3,9
30
Step-by-step explanation:
Edge 2021
The displacement is (-3, 9)
Work done= 30 Joules
What is vector?A vector is a quantity or phenomenon that has two independent properties: magnitude and direction.
Given:
F= (-1, 3)
point (3, -9)
So, displacement from origin to (3, -9)
d= (0-3, 0-(-9))
d= ( -3, 9)
Work done = F. d
= 3 + 27
= 30 joules.

Identify the percent of change as an increase or a decrease. 4/5 to 3/5 Increase Decrease Find the percent of change. Round to the nearest tenth of a percent if necessary.
The required percent of change from 4/5 to 3/5 is a decrease of 25%.
What is the percentage?The percentage is the ratio of the composition of value to the overall composition of value multiplied by 100.
Here,
The fraction 4/5 is greater than the fraction 3/5, so the change from 4/5 to 3/5 represents a decrease.
To find the percent of change, we first need to find the amount of change. We can do this by subtracting the original value (4/5) from the new value (3/5),
3/5 - 4/5 = -1/5
The amount of change is -1/5. To express this as a percent, we can use the formula.,
Percent change = (amount of change / original value) * 100%
Substituting the values we have,
Percent change = (-1/5 / 4/5) * 100%
Percent change = -0.25 * 100%
Percent change = -25%
Therefore, the percent of change from 4/5 to 3/5 is a decrease of 25%.

how do I find b of the traingal
Answer:
Pythagorean Theorum:
16ft
Step-by-step explanation:
pythagorean theorum states a^2+b^2=c^2
it only works for right triangles, c is the hypotenuse, a and b are the legs
so to find b we plug in the info we have!
7.8^2+b^2=17.8^2
next we simplify:
60.84+b^2= 316.84
subtract 60.84 from both sides to isolate the variable:
b^2=256
square root both sides
b=16
16ft is the answer
