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

Which function best represents this graph?
inverse operations to solve the equation.
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)
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
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
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.
Basically, the teacher wants a math equation story but I can't think of one.

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.

The photo below is being enlarged to form a 24- by 30-inch print. What is the scale factor being used to enlarge it? 5 ia
Answer: 6
Step-by-step explanation:
The the scale factor being used to enlarge the photo is 6. Therefore, option B is the correct answer.
What is scale factor?A scale factor is defined as the ratio between the scale of a given original object and a new object, which is its representation but of a different size (bigger or smaller).
The basic formula to find the scale factor of a figure is expressed as,
Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape.
Given that, the photo below is being enlarged to form a 24- by 30-inch print.
In the figure, the dimensions are 4 inches and 5 inches.
Scale factor = 24/4 = 6
and 30/5 = 6
Therefore, option B is the correct answer.

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
