Which of the following is the equation of a line that has a slope of 5 passes through the point (-3, 7)?
Answer:
y - 7 = m(x + 3)
Step-by-step explanation:
Apply the point-slope formula: y - k = m(x - h)
Then we have y - 7 = m(x + 3)

Adult tickets for the school musical are sold for $3.50 and student tickets are sold for $2.50 on a given night 425 tickets were sold for $ 1237.50. Wrote a system of linear equations for the problem
Answer:
3.5x + 2.50y = 1237.50
425 = x + y
Step-by-step explanation:
number of adult tickets: x
number of student tickets: y
3.5x + 2.50y = 1237.50
( value of adult ticket [3.50]* number of adult tickets [x]) + (value of student ticket [2.50] * number of student tickets [y]) = total value (1237.50)
425 = x + y
(number of adult tickets [x]) + (number of student tickets [y]) = total (425)
There is a guitar that originally costs $249.99. It is on sale for 15% off. You also have to pay 6% sales tax. How much will you pay for the guitar? Please show work!!!
Answer:
225.24099
Step-by-step explanation:
249.99(0.15) = 37.4985
249.99 - 37.4985 = 212.4915
212.4915(0.06) = 12.74949
212.4915 + 12.74949 = 225.24099

A full glass of water can hold 1/6 of a bottle.
How many glasses of water can be filled with 3 1/2. bottles of water?
Answer:
21 glasses
Step-by-step explanation:
6 glasses in a bottle
3 x 6 = 18
3 glasses in half a bottle
18 + 3 = 21
Answer:
21 glasses
Step-by-step explanation:
let 'g' = glasses of water
create a proportion, glasses over bottles equals glasses over bottles
1 = g
1/6 7/2
cross-multiply: 1/6g = 7/2
cross-multiply: 2g = 42
g = 21

Find the length of side BC.
Give your answer to 3 significant figures.
Answer:
BC ≈ 19.4 cm
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos71° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{AB}{BC}[/tex] = [tex]\frac{6.3}{BC}[/tex] ( multiply both sides by BC )
BC × cos71° = 6.3 ( divide both sides by cos71° )
BC = [tex]\frac{6.3}{cos71}[/tex] ≈ 19.4 cm ( to 3 significant figures )

Which of the following statements are true about inverse matrices?
All square matrices have inverses.
If A and B are inverse matrices, then A and B must be square matrices.
The determinant of a singular matrix is equal to zero.
If A and B are inverse matrices, then A + B = I.
If A and B are inverse matrices, then det(A)xde(B)=0
Any zero matrix does not have an inverse.
If B = A–1, then A = B–1.
B = A–1, then A = B–1. This statement is true. The inverse of a matrix is unique, so if B is the inverse of A, then A must be the inverse of B.
what is matrix ?An arrangement of integers in both columns and rows is known as a matrix. learns about matrices' components and dimensions and first presents them. A matrix is a rectangular grid with integers arranged in rows and columns.
The statements that are true about inverse matrices are:
Not all square matrices have inverses. A square matrix only has an inverse if its determinant is not equal to zero. If the determinant of a square matrix is zero, it is called a singular matrix and does not have an inverse.
If A and B are inverse matrices, then A and B must be square matrices. This is because only square matrices can have inverses.
The determinant of a singular matrix is equal to zero. This is because the determinant of a matrix is related to the linear independence of its columns or rows. A singular matrix has linearly dependent columns or rows, which means its determinant is zero.
If A and B are inverse matrices, then A + B = I. This is not necessarily true. In general, the sum of two inverse matrices is not necessarily the identity matrix.
If A and B are inverse matrices, then det(A) x det(B) = 1. This statement is almost true, but the correct statement is det(A) x det(B) = det(AB) = 1.
Any zero matrix does not have an inverse. This is because the determinant of a zero matrix is zero, and therefore it is singular and does not have an inverse.
If B = A–1, then A = B–1. This statement is true. The inverse of a matrix is unique, so if B is the inverse of A, then A must be the inverse of B.
