Answer:

(- 2, - 1 )

Step-by-step explanation:

Given the 2 equations

y = 2x + 3 → (1)

y = 3x + 5 → (2)

Substitute y = 3x + 5 into (1)

3x + 5 = 2x + 3 ( subtract 2x from both sides )

x + 5 = 3 ( subtract 5 from both sides )

x = - 2

Substitute x = - 2 into either of the 2 equations and evaluate for y

Substituting into (1)

y = 2(- 2) + 3 = - 4 + 3 = - 1

solution is (- 2, - 1 )

Answer:

8/5 oz

Step-by-step explanation:

The problem is saying that there are 8 ounces of cheese and 5 bowls of spaghetti you need to divide the cheese over. As you need an equal amount of cheese in each bowl, you have to divide 8 ounces by the number of bowls, which is 5. Thus, you would do 8 divided by 5, which we just say is 8/5. Therefore, your answer is 8/5 ounces of cheese (or simplified to 1 3/5).

Here is the complete question used in answering this question

he given cylindrical container r =3 inches and height= 8in is used to fill the rectangular prism fish tank 24 , 24 and 12 inches with water. What is the least number of full cylindrical needed to completely fill the fish tank?

Number of cylinders needed = volume of prism / volume of cylinder

volume of prism = width x height x length = 24 x 24 x 12 = 6912

volume of a cylinder = nr^2h

n = 22/7

r = radius

(22/7) x (3^2) x 8 = 226.29

6912 / 226.29= 30.54

Answer:

Another way to prove triangles are similar is by SSS, side-side-side. If the measures of corresponding sides are known, then their proportionality can be calculated. If all three pairs are in proportion, then the triangles are similar.

Answer: 10

Step-by-step explanation:

My answer is correct because, if x=5 then were just multiplying 2 times 5 since 5 is not on the top like [tex]2^{5}[/tex] because if it was that means we have to multiply 2 by itself 5 times. But since its not a exponent you just multiply 2 times 5. And 2 x 5= 10.

Hope This Helps!

Answer:

10

Step-by-step explanation:

2 where x is plug in 5

so 2(5)= 10

the answer would be 10

Explanation:

Pick any term that isn't the first term. Then subtract off the previous term. If we get the same result each time, then the sequence is arithmetic, and that result is the common difference.

We get -8 each time, so the sequence is arithmetic with common difference d = -8. It says to add -8 to each term to get the next term. This is the same as subtracting 8 from each term to get the next term.

Answer:

The measure of Angle M = 74.8°

Step-by-step explanation:

Cos(x) = [tex]\frac{adjacent}{hypotenuse}[/tex]

Cos(x) = [tex]\frac{26}{99}[/tex]

x = Cos⁻¹([tex]\frac{26}{99}[/tex])

x = 74.8°

So the measure of Angle M = 74.8°

Hope this helps!

Answer:

Trigonometry

since we have the adjacent and the hypotenuse we use CAH .We are looking for the angle we take the cos inverse

cos x = A

H

cos x = 26

99

x = cos -1 (26 ÷ 99)

x = 74.77404748

x= 74.8

Given:

Ty’s house is located ( 7,8) and the library is located ( 7,-6).

Each unit on the coordinate plane represents 1 block.

To find:

The number of blocks from Ty’s house to the library.

Solution:

Distance formula:

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

We need to find the distance between the two points ( 7,8) and ( 7,-6).

Using the distance formula, we get

[tex]D=\sqrt{(7-7)^2+(-6-8)^2}[/tex]

[tex]D=\sqrt{(0)^2+(-14)^2}[/tex]

[tex]D=\sqrt{196}[/tex]

[tex]D=14[/tex]

The distance between the two points ( 7,8) and ( 7,-6) is 14 units.

We know that, each unit on the coordinate plane represents 1 block.

Therefore, there are 14 blocks from Ty’s house to the library.

Answer: 28.8%

Step-by-step explanation:

First find out what her speed is:

Speed = Distance / Time

= 50 / 45

= 1.11 meters/second

Now her speed is:

= 50 / 35

= 1.43 meters/ second

The percentage increase in her speed is:

= (New speed - Old speed) / Old speed

= (1.43 - 1.11) / 1.11

= 0.288

= 28.8%

Answer:

Cost of each bag of chip = $1.5

Step-by-step explanation:

Given:

1 bag chips and 1 burger cost = $4

2 bag chips and 3 burger cost = $10.50

Find:

Cost of each bag of chips

Computation:

Cost of each bag of chip = c

Cost of each bag of burger = b

So,

c + b = 4 ......  eq1

2c + 3b = 10.50 ..... eq2

Eq1 x 2

2c + 2b = 8 ....... eq3

From eq2 - eq3

b = 2.5

From eq1

c + b = 4

c + 2.5 = 4

c = 1.5

Cost of each bag of chip = $1.5

Answer:

Angle between vectors u and v: 26.56 degrees

Step-by-step explanation:

I just recently did this question, so here's my response and hopefully that helps you:

Vector u is <-3,-4> and vector v is <-2,-1>. To find the angle between the two vectors, you first need to find their dot product. This means that u*v = <-3,-4> * <-2,-1> = (-3)(-2) + (-4)(-1) = 6 + 4 = 10. Second, you find the product of each of the vectors' magnitudes. The magnitude for vector u is ||u|| = sqrt((-3)^2 + (-4)^2) = sqrt(9+16) = sqrt(25) = 5. The magnitude for vector v is ||v|| = sqrt((-2)^2 + (-1)^2) = sqrt(4+1) = sqrt(5). The product of the magnitudes would thus be ||u||||v|| = 5sqrt(5). Third, divide the dot product by the product of the magnitudes which would be u*v/||u||||v|| = 10/5sqrt(5) = 2sqrt(5)/5. Lastly, you take the arccosine of the result which would be theta=cos^-1(2sqrt(5)/5) = 26.56 degrees, which is the angle between vectors u and v.

The explanation for determining the angle between the two vectors and find the angle in degrees should be explained below.

Since

vector v is from (0,0) to ( -2,-1)

So,

[tex]\bar{v}=-2i-j[/tex]

Here, vector u is from (0,0) to (-3,-4)

So,

[tex]\bar{u}=-3i-j4[/tex]

Now here we used dot product concept

Now

[tex]\bar{u}.\bar{v}=|u|.|v|cos\theta\\ \bar{u}.\bar{v}=(-3i-4j).(-2i-j)=6+4=10\\ |u|=\sqrt{9+16}=5\\ |v|=\sqrt{4+1}=\sqrt{5}\\ cos\theta=10/(5*\sqrt5)=2/\sqrt5\\ \theta=cos^{-1}(2/\sqrt5)= 26.56^o[/tex]

Answer:

x > -2

Step-by-step explanation:

-3x + 2 < 8

our goal is to isolate the x

subtract two from both sides

-3x < 8 - 2

- 3x < 6

divide both sides by -3

flip the sign because we divided by a negative number

x > -2

Answer:

3, 2, 1, 0

Step-by-step explanation:

f(-1) = |-1 - 2|  =  3

f(0) = |0 - (-2)|  =  2

f(1) = |1 - 2|  =  1

f(2) = |2 - 2|  =  0

Answer:

Diameter = 9

Step-by-step explanation:

Let the diameter be represented as x.

Based on the secant-tangent theorem, the following equation representing the relationship between the segments would be:

(16 + x)(16) = 20²

256 + 16x = 400

Subtract 256 from each side

16x = 400 - 256

16x = 144

Divide both sides by 16

x = 144/16

x = 9

Diameter = 9
