y=-3x+4
y=2x-1
what’s the solution?

Answer:

-12/5 or -2.4

Step-by-step explanation:

(-4/5) / (1/3) =

(-4/5) x (3/1) =

-12/5

-12/5 = -2.4

Answer:

[tex]\frac{-(\frac{4}{5})}{\frac{1}{3}} = -(\frac{4}{5}) * (\frac{3}{1} )= -\frac{12}{5}[/tex]

Step-by-step explanation:

1. Dividing fractions means multiplying the reciprocal-- so turn the fraction upside down and multiply by the first.

Answer:

Angle of elevation = 80°

Step-by-step explanation:

A princess is standing 38 feet from the base of a 217 foot tall tower. What is the angle of elevation from him to the ogre who has his princess held captive?

To solve for angle of elevation, we use the Trigonometric function of Tangent.

tan θ = Opposite side/Adjacent side

Opposite side = Height of the tower = 217 ft

Adjacent side = 38ft

tan θ = 217/38

tan θ = 5.6315789474

θ = arc tan 5.6315789474

= 79.930937301°

Approximately = 80°

Answer:

b) b=a/h

Step-by-step explanation:

A=bh

Dividing both side by h,

or, b=A/h

OR,

A=bh

or, b=A/h

[tex]\frac{x^2}{3}-\frac{1}{2}=\frac{x}{3}[/tex]

Because there are 3 and 2 as the denominators. Find the lowest number that both 3 and 2 can divide without any quotients, which is 6.

Multiply all whole equation by 6.

[tex]\frac{x^2}{3}(6)-\frac{1}{2}(6)=\frac{x}{3}(6)\\2x^2-3=2x[/tex]

We should get like this. Then move 2x to subtract.

[tex]2x^2-2x-3=0[/tex]

Because the polynomial is a two-degree and a quadratic equation. We solve the value of x by either factoring, using the formula or completing the square.

But I'll use the Quadratic Formula instead as the factoring doesn't seem to work for the Quadratic Equation with square root answers.

[tex]x=\frac{-b±\sqrt{b^2-4ac} }{2a}[/tex]

This is the formula of Quadratic Equation. Ignore the weird letter as it just randomly appears and can't be deleted.

[tex]x=\frac{-(-2)±\sqrt{(-2)^2-4(2)(-3)} }{2(2)} \\x=\frac{2±\sqrt{4+24} }{4} \\x=\frac{2±\sqrt{28} }{4}\\x=\frac{2±2\sqrt{7} }{4} \\x=\frac{1±\sqrt{7} }{2}[/tex]

Therefore, the answer is x = (1±√7)/2

Answer:

f(3) = 7

Step-by-step explanation:

To evaluate f(3), substitute x = 3 into f(x), that is

f(3) = 2(3) + 1 = 6 + 1 = 7

Answer:

The coordinates are (x,y) (-2,-3)

Step-by-step explanation:

We need to take note of the following properties.

1. A rectangle has 4 sides.

2. Two opposite sides of a rectangle are equal.

Coordinates of the triangle on the graph:  P(-2, 2), Q(4, 2), R(4, -3) and  S(x,y)

The length of the triangle:

We can get this from the x -coordinates of P and Q

Length = |-2 - 4| = 6 (We are only taking positive values for dimensions. You cannot have a negative length)

Recall that the length of the two sides is equal. Therefore, we can relate the length of the second side to its coordinates using the coordinates of R and S

x = 4-6; x = - 2

The breadth of the triangle

We can get this from the y -coordinates of Q and R

Breadth = |-3 -2| = 5 (We are only taking positive values for dimensions. You cannot have a negative breadth)

Recall that the breadth of the two sides is equal. Therefore, we can relate the breadth of the second side to its coordinates using the coordinates of R and S

2 - y = 5; y = -3

Therefore the coordinates are (x,y) (-2,-3)

Answer:

you need to add number lines, but if you want the equation to be written and solved, then...

Step-by-step explanation:

5x - 25 > -15

     +25    +25

5x > 10

divide both sides by 5

x > 2

Hope this helps!!!

Answer:

The mapping diagram that represents a relation that is not a function is the option A mapping diagram;

A. A mapping diagram with negative 6 pointing to negative 4 and 3; negative 1 pointing to 5; 7 pointing to 8

Step-by-step explanation:

The mapping diagrams of the given relations are presented using Microsoft Visio as seen in the attached drawings

From the given options, in option A, -5 is paired with both 4 and 3, therefore, giving an input or domain value, -5, that has two outputs in the range which are 4 and 3, therefore, the relationship between the left and right cells in option A is not a function because it is not defined as one input can have several outputs

Answer:

0.03

Step-by-step explanation:

3% as a fraction is 3/100. as a decimal it is 0.03. notice when you read the decimal aloud, it is three one-hundredths, which is also the same read aloud in a fraction.

Answer:

A

Answer: Profit of $3,750

Step-by-step explanation:

Sold half of the sets at a profit of 25%;

= (15,000 * 5 sets) * 25%

= $‭18,750‬

Sold the other half at a loss of 20%;

= (15,000 * 5) * 20%

= $15,000

Profit (loss) = 18,750 - 15,000

= $3,750

Answer:

20 units squared

Step-by-step explanation:

Using pythagorean theorum, we can find the hypotenuse(the long side). [tex]\sqrt{2^2 + 4^2} = \sqrt{20}[/tex]. Since the area of a square is one of the sides multiplied by itself, we get 20 units squared
