Answer:
[tex]x=\frac{13}{2}, y=\frac{51}{4}[/tex]
Step-by-step explanation:
[tex]We\ are\ given,\\3x-2y=-6\\5x-2y=7\\Considering\ this\ system\ of\ equations,\\Let\ 3x-2y=-6\ be\ E_1\\Let\ 5x-2y=7\ be\ E_2,\\Hence,\\Multiplying\ E2\ with\ -1, we\ get:\\3x-2y=-6\\-1(5x-2y)=7*-1\\Hence,\\3x-2y=-6\\-5x+2y=-7\\Now,\\Lets\ add\ E_1\ and\ E_2\ together\\Hence,\\(3x-2y)+(-5x+2y)=(-6)+(-7)\\Hence,\\3x-2y-5x+2y=-13\\Arranging\ And\ Adding\ Like\ terms,\ we\ have:\\3x-5x-2y+2y=-13\\Hence,\\-2x+0y=-13\\-2x=-13\\x=\frac{-13}{-2}=\frac{13}{2}[/tex]
[tex]Now,\ we\ can\ substitute\ x=\frac{13}{2}\ in\ E_1\ or\ E_2,\\But,\\Here,\ we'll\ substitute\ it\ in\ E1,\\Hence,\\Substituting\ x=\frac{13}{2}\ in\ E1,\ we\ have:\\3*\frac{13}{2}-2y=-6\\\frac{39}{2}-2y=-6\\-2y=-6- \frac{39}{2}\\-2y=\frac{-12-39}{2}\\-2y=\frac{-51}{2}\\y=\frac{-51}{2*-2}=\frac{51}{4}\\Hence,\\x=\frac{13}{2}, y=\frac{51}{4}[/tex]

Answer:
a) 1000+0.05x ≥2200
b) x=24000
Step-by-step explanation:
a) So we know that Nadia for certain gets paid $1000 each month. That is a concrete amount that doesn't change, so the variable (x) would be placed on the 5% she earns from sales. We don't know how much she sells each month because it varies, so that will be represented by the X. Her goal is to raise NO LESS than $2200, which means the amount she earns from sales has to be greater than or equal to $2200.
b) From here just solve the equation for X:
You deposit $100 in an
account that pays an

HELP!! I can't fail. 4 and 5 please!
Answer:
4) x = -3 or 8
Step-by-step explanation:
We factories each algebraic expression
4) x² -5x - 24 = 0
x² - 8x + 3x - 24 = 0
(x² - 8x) + (3x - 24) = 0
x(x - 8) + 3(x - 8) = 0
(x + 3)(x - 8) = 0
x + 3 = 0, x = -3
x - 8 = 0, x = 8
x = -3 or 8
HeLp! the question is on the picture.
Answer:
sin ∅ = 24/25
Step-by-step explanation:
These are the trigonometric ratios
Remember SOHCAHTOA
Sine = Opposite over Hypotenuse (SOH)
Cosine = Adjacent over Hypotenuse (CAH)
Tangent = Opposite over Adjacent (TOA)
We are asked to find sin ∅
The trig function sin = opposite over hypotenuse
so we need to find the opposite side length of the indicated angle (∅)
The opposite side length is equal to 24
Then we find the hypotenuse ( the longest side length ) which would be 25
so sin ∅ = 24/25

Find the distance between the two points rounding to the nearest tenth (In decimal).
Answer:
approximately 8.9
Step-by-step explanation:
Regard (3, -2) and (7, 6) as the two acute angle vertices of a right triangle. The horizontal leg of this triangle has the length (7 - 3) = 4, and the vertical leg 6 - (-2) = 8.
Apply the Pythagorean Theorem to find the length of the diagonal connecting these two points. This length is the distance between the two points:
d = √(4² + 8²) = √(16 + 64) = √80 + √16√5 = 4√5, or approximately 8.9
our points are labeled on the number line.

Carla and Marci are having a competition to see who can learn finish typing their research first. Carla already has 2 pages finished and can type 2 pages per hour. Marci has just started typing and can type 3 pages per hour. After how many hours will Carla and Marci have typed the same amount?
Answer:
The answer is 2 hours, if that i wrong then put in 3 hours.
Step-by-step explanation:
You could juat write out a chart for every number, so 2+0, 4+3, 6+6, so two hours.
Answer:
After 2 hoursStep-by-step explanation:
Let the time is x.
Carla will type:
2x + 2Marci will type:
3xSince they will have typed the same number:
3x = 2x + 23x - 2x = 2x = 2 hoursWhich function is graphed ?

Charlie has more than 50 game coins Charlie has 8 more than 3 times as game coins as Steven if x represents the number of game coins Steven has which inequality can be used to determine the possible number of game coins Steven has
Answer: [tex]x>14[/tex]
Step-by-step explanation:
Given
Charlie has more than 50 game coins
Steven has [tex]x[/tex] coins
So, according to the question, charlie has 8 more than 3 times the steven coins i.e.
[tex]\Rightarrow 3x+8[/tex]
Also, this must be greater than 50
[tex]\therefore 3x+8>50\\\Rightarrow 3x>42\\\Rightarrow x>14[/tex]

What is the coordinate of the midpoint of (2, 1) and (18, 7)?
Answer:
The midpoint is (10, 4)
Step-by-step explanation:
To find the midpoint, you add the x value from the first coordinate and the x value from the second coordinate, then divide by two to get the x coordinate of the midpoint. You do the the same exact thing with the two y values to find the y coordinate of the midpoint.
2 + 18 = 20
20 / 2 = 10

Find the value of sin^-1(4pi/5)
Answer:
No value because 4π/5 exceeds the domain
Step-by-step explanation:
The domain and range of sin^-1(x) is a domain of [-1,1] and a range of [-π/2,π/2]
Since 4π/5>1, this exceeds the domain and therefore has no value.
Can someone plz help me with the first one also it will be appreciated if u could show working out too!
Answer:
Angles in a quadrilateral add up to 360°.
[tex]90 + 3x + x + 20 + 2x + 10 = 360\\ 90 + 20 + 10 + 3x + x + 2x = 330\\ 120 + 6x = 360 \\ 6x = 360 - 120 \\ 6x = 240 \\ x = \frac{240}{6} \\ x = 40[/tex]
[tex]3x = 3 \times 40 = 120 \\ [/tex]
[tex]x + 20 = 40 + 20 = 60[/tex]
[tex]2x + 10 = 2 \times 40 + 10 = 80 + 10 = 90[/tex]
Difference between largest & smallest angles =
[tex]120 - 60 \\ = 60[/tex]
60 is the difference the largest & the smallest angle.
Find the measure of the missing angles.

Answer:
A profit is made when X>4, or after 4 thousand units.
Step-by-step explanation:
For starters the question states that for a profit to be made P(x) has to be greater than 0, and if you solve P(x) to equal 0 you get 4. Anything after 4 thousand would net the company a profit. You can also graph the equation and the x intercept, or 4 is also answer.

Mr. Sweeney's car can travel 195 miles on 10 gallons of gas. How far
can Mr. Sweeney travel if he buys 18 gallons of gas?
I
Answer:
Miles in 10 gallons = 195
Miles in 1 gallon = 195/10 = 19.5
Miles in 18 gallons = 19.5 × 18 = 351 miles.
Answer:
Miles travelled by the car on 10 gallons of gas = 195 miles
Miles travelled by the car in 1 gallon of gas = 195 ÷ 10 = 19.5 miles
Miles travelled by the car in 18 gallons of gas = 19.5 × 18 = 351 miles.

For how many minutes of calls with the cost of the two plans be equal?
Answer:
Let x = the number of minutes of calls
For Plan 1, we know that the monthly charge is 8 + 0.18x
For Plan 2, the monthly charge is 23 + 0.14x
To determine when the cost of the two plans will be equal, we set up the following equation:
8 + 0.18x = 23 + 0.14x
Can you solve for x, Alyssa?
