Answer
your anwser would be (2,5)
Step-by-step explanation:
y - x = 3 ...1
2x + y = 9 ...2
...2 - ...1
2x + y -y + x = 9 - 3
3x = 6
x = 2
replace x you will receive y value

What is the initial value of the equation shown?
y = -2x - 5
0-5
0-2
O2
05
Answer:
-5
Step-by-step explanation:
The initial value is the value of y when x has the value of 0.
Substitute 'x' for '0' and solve for 'y':
[tex]y=-2(0)-5\\\rightarrow -2*0=0\\y=0-5\\\boxed{y=-5}[/tex]
Option A should be correct.
Answer: -5
Step-by-step explanation:
Y= -2x - 5
+2. +2
-------------
Y= x(0)-5
So the initial value would be -5 because that would be x=0. Sorry if this is complicated I havent done it since the beginning of 6th grade.
What is the area of this figure?

On a coordinate plane, 2 exponential functions are shown. Function f (x) approaches y = 0 in quadrant 2 and increases into quadrant 1. Function g (x) approaches y = 0 in quadrant 1 and increases into quadrant 2.
Which function represents a reflection of f(x) = Three-eighths(4)x across the y-axis?
g(x) = NegativeThree-eighths (one-fourth) Superscript x
g(x) = Negative three-eighths(4)x
g(x) = Eight-thirds(4)-x
g(x) = Three-eighths(4)–x
Answer:
[tex]g(x)=f(-x)=\frac{3}{8}(4)^{-x}[/tex]
Step-by-step explanation:
The pre-image is
[tex]f(x)=\frac{3}{8}(4)^{x}[/tex]
To make a reflection across the y-axis, we need to apply the transformation
[tex](x,y) \implies (-x,y)[/tex]
Which give the function
[tex]g(x)=f(-x)=\frac{3}{8}(4)^{-x}[/tex]
Therefore, the right answer is the last choice.

An art teacher needs to buy at least 60 brushes for her class. The brushes are sold in packs of 8. In which inequality does n represent the minimum number of packs the teacher needs to buy for her class?
Answer:
I think 8n >_ 60
Im not sure but thats what i put
Step-by-step explanation:
The inequality where n represents the minimum number of packs the teacher needs to buy is: 8n ≥ 60.
What is Inequality?Inequality is an expression or statement of an order relationship, which involves the use of inequality signs, variables, numbers and/or algebraic expressions.
Thus:
n = number of brushes in a pack
The teacher must buy 60 brushes and above.
Thus:
8n ≥ 60 will represent the minimum number of brushes for the class.
Therefore, the inequality where n represents the minimum number of packs the teacher needs to buy is: 8n ≥ 60.

The value of a car depreciates by 40% each year. At the end of 2007 the value of the car was £3600 Work out the value of the car at the end of 2006 asap ples
Answer: $6,000
Step-by-step explanation: If set up correctly, the value of the car at the end of 2006 times 0.6 (because the car is losing 0.4 of its value, so it keeps 0.6 of its value) should get you the value of the car at the end of 2007.
The equation should look like this:
(value of the car at the end of 2006) x 0.6 = (value of the car at the end of 2007)
Then you substitute: (value at the end of 2006) x 0.6 = 3600
Then divide: (value at the end of 2006) = 0.6 ÷ 3600
Then substitute again: (value at the end of 2006) = 6,000

John charges a flat fixed fee of $10 PLUS a certain rate per hour for each hour for cutting the grass. John earned $100 one day, cutting the grass in a circular lawn. On the next day, to cut the grass in a similar adjacent circular lawn one third the circumference, how much money can he expect to make? ( with explanation )
Answer:
33.33 dollars
Step-by-step explanation:
Answer:
$20
Step-by-step explanation:
Of the $100 John earned, $90 was for his hourly charge, which we assume is proportional to the area being mowed.
A lawn with 1/3 the circumference has (1/3)^2 = 1/9 the area, so presumably takes 1/9 of the time to mow. John's hourly charge for the smaller lawn will be $90/9 = $10. Added to his flat fee, he can expect to be paid $20.
_____
The ratio of areas of similar figures is the square of the ratio of any of the linear dimensions. All circles are similar. Circumference is measured in "units" and area is measured in "square units." So, circumference is a linear dimension (units to the first power).
What is the value of b?
A. 100
B. 90
C. 80
Answer: the answer is C. 80°
Step-by-step explanation:
= 360 - 110 - 90
=160°
b=1/2 (160)
b=80°
Answer:
C. 80 degrees
Step-by-step explanation:
The measure of the given arcs are 90 and 110.
Subtract those values from 360
= 360 - 90 -110
= 160
The angle b is half of 160 degrees, the measure of the arc that intercepts it.
Therefore, it measures 80 degrees.

Round to one decimal place (BRAINLIEST)
Answer:
4.3
Step-by-step explanation:
Apply trigonometric ratios to find the answer.
Firstly, we need to find the measure of angle theta. In order to do this, we will use triangle BAD.
From angle theta, the trigonometric ratio sine can be used:
sinθ = [tex]\frac{4.1}{5.3}[/tex]
After we find the value, we take the inverse sine of it and the result is approximately 50.7 degrees.
Now, knowing that angles BAD and CAD are the same, we can solve for CD using trigonometric ratio sine.
sin50.7 = opposite/hypotenuse
sin50.7 = CD/5.5
sin50.7 * 5.5 = CD
4.3 ≈ CD

What is a function?A function is an assertion, concept, or principle that establishes an association between two variables. Functions may be found throughout mathematics and are essential for the development of significant links.
A basketball is shot into the air. Its height is represented by the polynomial equation which is given below.
h(t) = –16t² + 35t + 5
Where h is the height of the basketball at t seconds.
The height of the basketball at 1 second will be given as,
h(1) = –16 × (1)² + 35 × 1 + 5
h(1) = –16 + 35 + 5
h(1) = –16 + 40
h(1) = 24 feet
The height of the basketball at 1 second will be 24 feet. Then the correct option is A.
