9x-y=17 and 5x+4y=-27 solve by substitution
Answer:
(1, -8)
Step-by-step explanation:
Solve by Substitution
9x − y = 17 and 5x + 4y = −27
Solve for y in the first equation.
y = −17 + 9x 5x + 4y = −27
Replace all occurrences of y with −17 + 9x in each equation.
Replace all occurrences of y in 5x + 4y = −27 with −17 + 9x. 5x + 4 (−17 + 9x) = −27
y = −17 + 9x
Simplify 5x + 4 (−17 + 9x).
41x − 68 = −27 y = −17 + 9x
Solve for x in the first equation.
Move all terms not containing x to the right side of the equation.
41x = 41
y = −17 + 9x
Divide each term by 41 and simplify.
x = 1
y = −17 + 9x
Replace all occurrences of x with 1 in each equation.
Replace all occurrences of x in y = −17 + 9x with 1. y = −17 + 9 (1)
x = 1
Simplify −17 + 9 (1).
y = −8
x = 1
The solution to the system is the complete set of ordered pairs that are valid solutions.
(1, −8)
The result can be shown in multiple forms.
Point Form:
(1, −8)
Equation Form:
x = 1, y = −8

Jason and his friends spent $62 at the movies. Admission tickets cost $12 apiece, and a bucket of popcorn costs $7. Which equation written in standard form represents the number of tickets bought, t, and the number of buckets of popcorn bought, p? a 12p = 62 – 7t b 12p + 7t = 62 c 7p + 12t = 62 d 7p = 62 – 12t
Answer:

Step-by-step explanation:
Express 57/16 as a decimal.
What does t equal in 1/3t-8=-6
Answer:
t=6
Step-by-step explanation:
Solve for tt by simplifying both sides of the equation, then isolating the variable.
Answer:
t=6
Step-by-step explanation:
We first use the addition property of equality by adding 8 to both sides. This cancels out the "-8" on the left-hand side of the equation.
We get: 1/3t= 2.
Then, we multiply 3 to both sides of the equation to cancel out the fraction on the left-hand side of the equation.
We get: t=6
This is your final answer.
I hope this helps!

x2 + 3x
x = 1.7
Answer:
8.5
Step-by-step explanation:
Our current equation is:
x2 + 3x.
Let's replace all the x with 1.7.
1.7(2) + 3(1.7)
Let's solve this new equation normally, as if the 1.7 was always there.
1.7(2) = 3.4
3(1.7) = 5.1
Now, let's add both the products.
5.1 + 3.4 = 8.7
Therefore, we can conclude the answer is 8.7.

In triangle, STU, ST = 52, and TU = 39. What is the range of values for the length third side?
A - (-13 < SU < 13)
B - (13 < SU < 91)
C - (13 < SU < 52)
D - (-13 < SU < 91)
The range of values for the length third side is (13 < SU < 52) Which is correct option (C).
What is inequality?Inequality is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is not equal.
In triangle Δ STU,
Side ST = 52,
And Side TU = 39.
Let missing side is smallest than other sides,
According to the sides of a triangle rule asserts that,
The sum of the lengths of any two sides of a triangle has to be greater than the length of the third side. The sum of the lengths of the two shortest sides TU and Side SU. That length is greater than the length of the longest side ST.
So, Side ST < Side SU + Side TU
⇒ 52 < Side SU + 39
⇒ 52 - 39 < Side SU
⇒ 13 < Side SU
Since, Side ST is largest side So Side SU can not be greater than 52
Therefore, the range of values for the length side SU :
⇒ 13 < Side SU < 55
Hence, the range of values for the length third side is (13 < SU < 52).

As soon as a new car is purchased and driven away from the dealership, it begins to lose its value, or depreciate. Alonso bought a 1994 Plymouth Neon for $13500. One year later, the value of the car was $9000. What was the percent of decrease of the value of the car? (Note: Round answer to the nearest whole number percentage.)
Answer: 33.3%
Step-by-step explanation:
Cost price of the car = $13500
Value of car one year later = $9000
Decrease in value of car = $13500 - $9000 = $4500
The percent of decrease of the value of the car will then be:
= Decrease in value of car / Cost price × 100
= $4500 / $13500 × 100
= 1/3 × 100
= 33.3 %

An international company has 27,100 employees in one country. If this represents 22.6% of the company's employees, how many employees does it have in total? Round your answer to the nearest whole number.
Answer:
The total employee of the company is 11912
Step-by-step explanation:
The employee in one country = 27,100
Let the total population be P
[tex]\frac{ 22.6}{100} *P = 27,100[/tex]
P = [tex]\frac{27100*100}{22.6}[/tex]
P = 11911.5
P = 11912 (approximately)
So the total employee of the company is 11912

What is the equation of this line in slope-intercept form?
Answer:
y = -3x + 2
Step-by-step explanation:
y = mx + b
m is the slope and b is the y-intercept
So the slope is -3 as it's going down, down is negative, by 3 units and only going to the right one unit while doing so. The y-intercept is where the line is intercepting on the y-axis. So it's: y = -3x + 2
(1, 4) Slope = -8
