It looks like you're given a set
{(x, y) : y = 3x + 2}
i.e. the set of points (x, y) = (x, 3x + 2), and you're told that x is taken from the set {-2, -1, 0, 1, 2}.
When x = -2, the corresponding value of y is
y = 3•(-2) + 2 = -6 + 2 = -4
Hey Rachael is removed from a rectangle to create the shaded region chandelier find the area of the shaded region be sure to include the correct unit in youranswer
Answer:
34.5 cm²
Step-by-step explanation:
The area of the shaded region is the area of the rectangle minus the area of the right triangle.
The area of the rectangle is simply the length 7 cm multiplied by the width 6 cm.
To find the area of the right triangle, you must first find the base and height of the triangle.
The two lengths can be found this way:
7 cm - 2 cm = 5 cm
6 cm - 3 cm = 3 cm
area of shaded region = LW - bh/2
area of shaded region = 7 cm × 6 cm - 5 cm × 3 cm / 2
area of shaded region = 42 cm² - 7.5 cm²
area of shaded region = 34.5 cm²
A cookie recipe for 60 cookies calls for 4 cups of flours how much flour or s needed to make 90 cookies
Answer:
6 Cups of Flower
Step-by-step explanation:
First form a ratio
Cookies:Flour
60:4
Simplify
15:1
Since we now need to find the amount of cups for 90 cookies we must finds the amount of flower.
90:X
Using our old ratio of 15:1 we must divide 90/15 in order to get a factor to multiply 1 to make 15:1 equivalent to 90:X.
90/15 = 6 | 6 is the factor
15(6):1(6)
90:6

Find the angle measures.
Answer:
∠ 1 = 155° , ∠ 2 = 25°
Step-by-step explanation:
the 2 angles are adjacent angles and sum to 180° , that is
5x + x - 6 = 180
6x - 6 = 180 ( add 6 to both sides )
6x = 186 ( divide both sides by 6 )
x = 31
then
∠ 1 = 5x = 5(31) = 155°
∠ 2 = x - 6 = 31 - 6 = 25°

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.
A dairy farmer uses two trucks to deliver milk. The two trucks use different kinds of fuel. Truck A uses gasoline and Truck B uses diesel.
From the given table we can see that
The total number of gallons of diesel Truck B used to travel 12 miles = 1
Number of gallons of diesel Truck B used to travel 1 mile = 1 /12
The total number of gallons of diesel Truck B used to travel 132 miles
= 1 /12 x 132
= 132 / 12
= 11
Thus, The total number of gallons of diesel Truck B used to travel 132 miles is 11.

Three times a number plus three times a second number is negative twelve. Five times the first number plus twice the second is four
Consider the numbers as, if we assume our first number to be x and second number being y, then from the given information we will be having the following equations :
[tex]{:\implies \quad \begin{cases}\sf 3x+3y=-12\\ \\ \sf 5x+2y=4\end{cases}}[/tex]
Now, rewrite the second equation as ;
[tex]{:\implies \quad \sf 3(x+y)=-12}[/tex]
Divide both sides by 3 ;
[tex]{:\implies \quad \sf x+y=-4\quad ---(i)}[/tex]
Now, consider the second equation of the above cases
[tex]{:\implies \quad \sf 5x+2y=4\quad ---(ii)}[/tex]
Now, multiply (i) by 2 on both sides :
[tex]{:\implies \quad \sf 2x+2y=-8\quad ---(iii)}[/tex]
Now, subtracting (ii) from (iii) will give us :
[tex]{:\implies \quad \sf 2x+2y-(5x+2y)=-8-4}[/tex]
[tex]{:\implies \quad \sf 2x+2y-5x-2y=-12}[/tex]
[tex]{:\implies \quad \sf -3x=-12}[/tex]
[tex]{:\implies \quad \boxed{\bf{x=4}}}[/tex]
Now, putting x = 4 in (i), will give y + 4 = -4, then solving for y will yield [tex]{\boxed{\bf{y=-8}}}[/tex]
Hence, we can conclude that :
[tex]{\quad \qquad \longrightarrow \begin{cases}\bf x=4\\ \\ \bf y=-8\end{cases}}[/tex]

Find the general solution of the differential equation and check the result by differentiation. (Use C for the constant of integration) dy/dt = 27t^8 y = Find the general solution of the differential equation and check the result by differentiation. (Use C for the constant of integration.) dy/dx =8x^7/9 y =
Answer: [tex]y=Ce^(^3^t^{^9}^)[/tex]
Step-by-step explanation:
Beginning with the first differential equation:
[tex]\frac{dy}{dt} =27t^8y[/tex]
This differential equation is denoted as a separable differential equation due to us having the ability to separate the variables. Divide both sides by 'y' to get:
[tex]\frac{1}{y} \frac{dy}{dt} =27t^8[/tex]
Multiply both sides by 'dt' to get:
[tex]\frac{1}{y}dy =27t^8dt[/tex]
Integrate both sides. Both sides will produce an integration constant, but I will merge them together into a single integration constant on the right side:
[tex]\int\limits {\frac{1}{y} } \, dy=\int\limits {27t^8} \, dt[/tex]
[tex]ln(y)=27(\frac{1}{9} t^9)+C[/tex]
[tex]ln(y)=3t^9+C[/tex]
We want to cancel the natural log in order to isolate our function 'y'. We can do this by using 'e' since it is the inverse of the natural log:
[tex]e^l^n^(^y^)=e^(^3^t^{^9} ^+^C^)[/tex]
[tex]y=e^(^3^t^{^9} ^+^C^)[/tex]
We can take out the 'C' of the exponential using a rule of exponents. Addition in an exponent can be broken up into a product of their bases:
[tex]y=e^(^3^t^{^9}^)e^C[/tex]
The term e^C is just another constant, so with impunity, I can absorb everything into a single constant:
[tex]y=Ce^(^3^t^{^9}^)[/tex]
To check the answer by differentiation, you require the chain rule. Differentiating an exponential gives back the exponential, but you must multiply by the derivative of the inside. We get:
[tex]\frac{d}{dx} (y)=\frac{d}{dx}(Ce^(^3^t^{^9}^))[/tex]
[tex]\frac{dy}{dx} =(Ce^(^3^t^{^9}^))*\frac{d}{dx}(3t^9)[/tex]
[tex]\frac{dy}{dx} =(Ce^(^3^t^{^9}^))*27t^8[/tex]
Now check if the derivative equals the right side of the original differential equation:
[tex](Ce^(^3^t^{^9}^))*27t^8=27t^8*y(t)[/tex]
[tex]Ce^(^3^t^{^9}^)*27t^8=27t^8*Ce^(^3^t^{^9}^)[/tex]
QED
I unfortunately do not have enough room for your second question. It is the exact same type of differential equation as the one solved above. The only difference is the fractional exponent, which would make the problem slightly more involved. If you ask your second question again on a different problem, I'd be glad to help you solve it.

Answer:
278°
Step-by-step explanation:
You want the measure of arc RSQ given inscribed angle RSQ has a measure of 41°.
Inscribed angleAn inscribed angle has half the measure of the arc it subtends. This means short arc RQ will have double the measure of angle RSQ:
arc RQ = 2 × 41° = 82°
Long arcThe measure of long arc RSQ will complete the 360° circle:
arc RSQ = 360° -arc RQ
arc RSQ = 360° -82°
arc RSQ = 278°

Answer:
m∠F = 100
Step-by-step explanation:
Sum of interior angles in a hexagon is 720.
( x - 60 ) + ( x - 40 ) + 130 + 120 + 110 + ( x - 20 ) = 720
x + x + x - 60 - 40 - 20 + 130 + 120 + 110 = 720
3x - 120 + 120 + 130 + 110 = 720
3x + 130 + 110 = 720
3x + 240 = 720
3x = 720 - 240
3x = 480
x = 480 / 3
x = 120
m∠F = x - 20
Substitute the value of x,
m∠F = 120 - 20
m∠F = 100

Answer:
x = 2
Step-by-step explanation:
24 - 7x = 10
Rearrange terms,
-7x + 24 = 10
Subtract 24 from both sides,
-7x + 24 - 24 = 10 - 24
-7x = 10 - 24
-7x = -14
Divide by sides by -7,

[tex]x=\frac{-14}{-7}[/tex]
