A system of equations is shown below.
y = 2x - 3
y = 5x + 6
What is the value of x + y?
A. -12
B. -9
C. 9
D. 12
Please help me!!!!
Answer:
-12
Step-by-step explanation:
Step1: Add 3 to both sides of the equation
2x -3 = 5x +6
+3 +3 = 9
Step2: subtract 5x from both sides of the equation
2x = 5x +9
-5 -5
Step3: divide both sides of the equation by the same term
-3x(/ -3) = 9(/-3)
X=-3Step4: multiply -3 with 2
-3x2= -6
Step4: subtract -6 with 3
-6 - 3= -9
Y=-9Step5: add the -9 to -3
-9 + -3 = -12
ANSWER: -12

Sasha hikes into a canyon. She takes a break at the rest stations every 2/3 of a mile.
If she started at sea level and has hiked down to the fourth rest station, what is Sasha’s elevation now?
Select all that apply.
Answer:
The correct options are;
A. [tex]-\dfrac{8}{3} \ miles[/tex]
D. [tex]2\dfrac{2}{3} \ mile[/tex] below sea level
Step-by-step explanation:
The given parameters are;
The distance Sasha travels down before a stop = -2/3 mile
The level at which Sasha starts to hike into the canyon = Sea level
Therefore, we have;
Her elevation at the fourth rest station = 4 × -2/3 mile = -8/3 miles
Therefore, we have;
-8/3 mile = [tex]2\dfrac{2}{3} \ mile[/tex] below sea level
Therefore, the correct options are;
-8/3 mile and [tex]2\dfrac{2}{3} \ mile[/tex] below sea level.

5.) g(x) = -4x + 2. Find x when g(x) = 22.
I'm on a timed test and I wasn't able to study because of personal reasons
Answer:
x = -5
Step-by-step explanation:
If g(x) = 22 and g(x) = -4x + 2, then -4x + 2 = 22.
Isolate x.
-4x = 22 - 2
= -4x = 20
= x = 20 ÷ -4
= x = -5

c. Find and interpret A(r(x))
What's the intercepts of the line 4x-3y=17
X[__,__]
Y[__,__]
Answer: REMEMBER (X, Y)
x(4 1/4, 0)
y(0, -5 2)
Step-by-step explanation:
Find the x-intercept
To find x intercept subtract y equals 0
4 x - 3 × 0 = 17
Any equation multiplied by 0 equals 0
4x - 0 = 17
When adding or subtracting zero quality does not change
4x = 17
Divide both sides of the equation by 4
x = 17/4
Solution
X = 17/4
Alternate form
X = 4 1 / 4, x = 4.25
Find y-intercept
To find y intercepts subtract x equals 0
4 × 0 - 3y = 17
Solve the equation for y
Y = -17 / 3
Solution
y = -17 / 3
Alternate form
y = -5 2 / 3, y = -5.6
Which expression is equivalent?
A concession stand charges $2.50 for a bag of popcorn. The stand has already sold 30 bags of popcorn. How many more bags x of popcorn must be sold to earn at least $110? Write your answer as a inequality Pls help me :(
Answer:
The concession stands needs to sell 14 or more bags.
Step-by-step explanation:
Given that:
Cost per bag of popcorn = $2.50
Number of bags already sold = 30
Cost of 30 bags = 30*2.50 = $75
Bags needs to be sold to make $110 = x
2.50x + 75 ≥ 110
2.50x ≥ 110-75
2.50x ≥ 35
Dividing both sides by 2.50
[tex]\frac{2.50x}{2.50}\geq \frac{35}{2.50}\\x\geq 14[/tex]
Hence,
The concession stands needs to sell 14 or more bags.

2/3(z)=(-2)
Answer: z = -3
Step-by-step explanation:
2/3z = -2
2z = -6 (Multiply both sides by 3)
z = -3 (Divide both sides by 2)
8х + 5у = -7
— 7х + бу = — 4
Answer: x = -0.2651 and y = -0.9759
Step-by-step explanation:
Solution by substitution method
8x+5y= -7
-7x+6y= -4 = 7x-6y=4
Suppose,
8x+5y=-7→(1)
7x-6y=4→(2)
Taking equation (1), we have
8x+5y= -7
⇒8x= -5y -7
⇒x= -5y-7 / 8 →(3)
Putting x= -5y-7 / 8
in equation (2), we get 7x-6y=4
7(-5y-7/8)-6y=4
⇒-35y-49-48y=32
⇒-83y-49=32
⇒-83y=32+49
⇒-83y=81
⇒y= 81 / -83
⇒y= -0.9759→(4)
Now, Putting y= -0.9759 in equation (3), we get
x= -5y-7
x= -5(-0.9759)-7/8
⇒x= 4.8795-7/8
⇒x= -2.1205/8
⇒x= -0.2651
∴x= -0.2651 and y = -0.9759

Anna has a box of chocolates. In the box there are milk, plain and white chocolates in the ratio 4:3:2. Anna doesn't like white chocolates. Work out the probability that she will pick a chocolate that is not white? *
Complete question :
Anna has a box of chocolates. In the box there are milk, plain and white chocolates in the ratio 4:3:2. The box contains 72 chocolates altogether. Anna doesn't like white chocolates. Work out the probability that she will pick a chocolate that is not white?
Answer:
7 / 9
Step-by-step explanation:
Calculate the number of each type of chocolate :
Milk : plain : white = 4 : 3 : 2
Total ratio = (4 +3 +2) = 9
Milk = (4/9) * 72 = 32
Plain = (3/9) * 72 = 24
White = (2/9) * 72 = 16
Probability of picking a chocolate that is not white :
Number of non-white :
(plain + milk) = (24 + 32) = 56
Probability = (required outcome / Total possible outcomes)
P(not white chocolate) = (number of non-white / total number of chocolates)
= 56 / 72
= 7 / 9
solve the Inequality
8p<-3
Answer:
Step-by-step explanation:
8p < -3
You must isolate P
In order to do this, you need to get rid of anything on that side.
P is being multiplied by 8, so you must do the inverse in order to get rid of it.
The opposite of multiplying is dividing, so divide BOTH sides by 8.
8p / 8 < -3 / 8
You are left with:
p < -3 / 8
That is the answer
Find the slope of the line that passes through (10,9) and (1,1).
