Answer:
Step-by-step explanation:
-4x - 3 = - 19
Bringing like terms on one side
-4x = - 19 + 3
-4x = - 16
x = - 16/-4
x = 4
Answer:
x=4
Step-by-step explanation:
-4x-3=-19
add -3 to the right side of the equation so -19+3
which will give you -16
then divide by -4
so x=4
4•4 - (-1)
Does this equal 3
Answer:
no, 4×4=16
16-(-1)=16+1=17
Answer: no it equal 17.
Step-by-step explanation: do 4 times 4 then you have 16-(-1) then change to 16+1 which equals 17.

For questions 9 and 11, solve for the remaining angles.
Answer:
‹A = 141°
‹B = 28°
‹C = 11°
*These angles are rounded to the nearest whole*
Step-by-step explanation:
Because you are only given sides you can find an individual angle measures with the inverse law of cosines.
Remember the side opposite of the angle corresponds to that angle.
a² = b² + c² - 2bc cos(A) →
A = cos⁻¹ (a² - b² - c² / -2bc)
b² = a² + c² - 2ac cos(B) →
B = cos⁻¹ (b² - a² - c² / -2ac)
c² = a² + b² - 2ab cos(C) →
C = cos⁻¹ (c² - a² - b² / -2ab)

A multiplier of 1.641 corresponds to a percentage increase or decrease of what percent?
Answer:
A multiplier of 1.641 corresponds to a percentage increase or decrease of 64.1%.
Step-by-step explanation:
To determine a percentage increase or decrease of a certain number, a calculation consisting of the multiplication of said number by 1 plus the decimals corresponding to the percentage to be increased must be performed. Thus, for example, if you want to increase a number by 50%, you must multiply that number by 1.50. Therefore, if you multiply a number by 1,641, this implies that you are wanting to increase or decrease the initial number by 64.1%.

Determine if the statement is true or false. A system in echelon form can have more variables than equations. True False
Answer:
True.
Step-by-step explanation:
A system of a mathematical expression such as a matrix is said to be in echelon form when it has many variables.
There are two (2) forms of echelon matrices and these includes;
I. Reduced row echelon form (RREF)
II. Row echelon form (REF)
Hence, a system in echelon form can have more variables than equations.

Ann Nguyen would like an installment loan for $5,750. Her bank will loan her the
money at 18% for 18 months. Her insurance company will loan her the money at
18% for 24 months. How much money will she save by choosing the smarter loan?
9514 1404 393
Answer:
$281.40
Step-by-step explanation:
A financial calculator tells you the payment for the 18-month loan is $361.46, so her total payback amount is $6506.28.
Similarly, the payment for the 24-month loan is $282.82, and the total amount repaid is 6787.68.
The shorter-term loan costs less by ...
$6787.68 -6506.28 = $281.40
Ann can save $281.40 by choosing the shorter-term loan.
