Answer: (x,y) -> (7/4x, 7/4y)

Step-by-step explanation:

Answer:

-38

Step-by-step explanation:

Let's say that x= 1st number and y=2nd number.

In order to find the first number,  you have to find out the 2nd number which it says, "5 less than a second number", it would be y-5. then it says the "5 times the first is 8 more than 6 times the second". then there should be an equal sign because there is the word "is". The expression would be: 5(y-5)=6y+8. then solve the y. which is -33, then plug in the y to the y-5 and there you go!

Answer:

x = 2

Step-by-step explanation:

Distribute

3 (−4) = 2 (−2+1)

3 − 12 = 2 (-2x +1)

Distrubute again

3x - 12 = -4x + 2

Add twelve to both sides of the equation

Simpfly

3x = -4x + 14

Add 4x to both sides of the equation

simpfly

7x = 14

Divide both sides of the equation by the same term

Simpfly

x = 2

Answer:

9.2

Step-by-step explanation:

S.A.S.→Law of Cosines

a^2=b^2+c^2-2bc\cos A

From reference sheet.

h^2 = 9.2^2+1.4^2-2(9.2)(1.4)\cos 84

=84.64+1.96−2(9.2)(1.4)(0.104528)

Square and find cosine.

h^2 = 84.64+1.96-2.69265

h  

2

=84.64+1.96−2.69265

Multiply.

h^2 = 83.90735

h  

2

=83.90735

Add.  

h=  

83.90735

​  

≈9.16≈9.2

The required measure of the length of h is 9.2 centimeters.

These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.

here,

Law of Cosines

In ΔHIJ, i = 9.2 cm, j = 1.4 cm and ∠H=84°

Following the cosine rule

a²=b²+c²-2bc×cos A

From given

h² = 9.2²+1.4²- 2(9.2)(1.4) × cos 84

h² = 84.64+1.96-2.69265

h²  = 84.64+1.96 −2.69

h² = 83.9

h ≈9.2

Thus, the required measure of the length of h, to the nearest 10th of a centimeter is 9.2 centimeters.

Answer:

x=3, y=5

Step-by-step explanation:

Answer:

I use equal signs throughout but they are meant to be less than or equal to signs.

s=sandwiches

4.5s+6 less than or equal to 50

The answer is s is less than or equal to 12

Step-by-step explanation:

Finding Inequality

1. we know everything costs 50 in total so that is on one side of the equal sign.

____=50

2. we know he already spent 6 dollars so the money he can spend is 6 dollars less.

____+6=50

3. Each sandwich costs 4.50 $ so how much money does he have left to spend? we figure that out by multiplying the price by the number of sandwiches.

4.5s+6=50

Solving

1. 4.5s-6=50

First use the addition property of equality and add 6 to both sides.

2. 4.5s=56

Then use the division property of equality and divide each side by 4.5

3. you get a decimal but since you can't buy half a sandwich the answer is

s is less than or equal to 12

Answer:

30 = b * ?

b = 2 * ?

Step-by-step explanation:

b = books

2 = price of each book

30 = b * ?

or

b = 2 * ?

Given:

The two points are (-1,2) and (5,-2).

To find:

The distance between the given points.

Solution:

Distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using the distance formula, the distance between the given points is

[tex]d=\sqrt{(5-(-1))^2+(-2-2)^2}[/tex]

[tex]d=\sqrt{(5+1)^2+(-4)^2}[/tex]

[tex]d=\sqrt{(6)^2+16}[/tex]

[tex]d=\sqrt{36+16}[/tex]

On further simplification, we get

[tex]d=\sqrt{52}[/tex]

[tex]d=7.2111[/tex]

[tex]d\approx 7.21[/tex]

Therefore, the the distance between the given points is about 7.21 units.

Answer:

[tex]y<16[/tex]

Step-by-step explanation:

Step-by-step explanation:

The formula for the slope is y=mx+b, where m is the slope and b is the y-intercept. Since 2 is being multiplied by x, that means it is the slope. The variable y is being added, so it has to be the y-intercept.

Answer:

2=slope & y-intercept=y

Answer:

the slope is -2 and the y-intercept is 3

Step-by-step explanation:

you can rearrange the equation into y=mx+b form which will be y = -2x + 3

the m in y=mx+b is the slope, which in this case is -2.

and the y-intercept is 3 bc is the only constant in the equation.

Answer:

43.5 cm² and 112 cm²

Step-by-step explanation:

Here the instructions aren't given what to do. So I am finding the area of the ∆s .

Area of first ∆ :-

Area of second ∆ :-

Answer:

[tex] \displaystyle 3) \boxed{ \rm {43.5 \: cm}^{2} }[/tex]

[tex] \displaystyle 4)\rm \boxed{112 {cm}^{2} }[/tex]

Step-by-step explanation:

we are given a triangle and we want to figure out the area of it Since we are given the base and the height we can consider the following formula

[tex] \displaystyle \frac{1}{2} bh[/tex]

from the triangle we can assume base and height as 14.5 and 8 respectively Thus substitute:

[tex] \displaystyle \frac{1}{2} (14.5cm)(6cm)[/tex]

reduce fraction:

[tex] \displaystyle (14.5cm)(3cm)[/tex]

simplify multiplication:

[tex] \displaystyle \boxed{ \rm {43.5 \: cm}^{2} }[/tex]

our given shape is trapezoid

therefore recall that,

[tex] \displaystyle A _{ \text{trapezoid}} = \frac{a + b}{2} h[/tex]

from the shape we define that

now substitute:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = \frac{9cm + 19cm}{2} (8cm)[/tex]

reduce fraction:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = (9cm + 19cm)(4cm)[/tex]

simplify addition:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = (28cm)(4cm)[/tex]

simplify multiplication:

[tex] \displaystyle \rm A _{ \text{trapezoid}} = \boxed{112 {cm}^{2} }[/tex]

Answer:

Y= 1/3x-15

Step-by-step explanation:

-6=-3(-3)+b

-6= 9+b

subtract 9 on both sides

b= -15

Y= 1/3x-15

because its perpendicular the -3x become positive and reciprocal

Answer:

Y= 1/3x-15

Answer:

1. Yes

2. 112 ounces

Step-by-step explanation:

To answer this question, we should first convert the amount of pounds Rick's cat weighs into ounces, so that both measurements are in the same unit. Since 1 pound is the same as 16 ounces, we can multiply 7 pounds by 16 ounces:

7 * 16 = 112

So, Rick's cat weighs 112 ounces, which is more than his neighbor's puppy, which only weighs 103 ounces. so for the first question, the answer is:

Yes, Rick's cat weighs more than the puppy.

And the second answer is:

Rick's cat weighs 112 ounces.

Hope this helps :)
