Answer:

Part A) The rate is [tex]\frac{12}{4}\ \frac{feet}{years}[/tex]

Part B) In 1 year the tree grows 3 feet

Step-by-step explanation:

Part A)  write the rate at which this tree grows as a fractions

we know that

To find out the rate at which the tree grows divide 1/4 foot by 1/12 year

so

[tex]\frac{(1/4)}{(1/12)}=\frac{12}{4}\ \frac{feet}{years}[/tex]

Part B) how many feet does the tree grow in 1 year?

we know that

The tree grows at rate of [tex]\frac{12}{4}\ \frac{feet}{years}[/tex]

Simplify

[tex]\frac{3}{1}\ \frac{feet}{year}[/tex]

That means ----> The tree grows 3 ft in 1 year

therefore

In 1 year the tree grows 3 feet

Answer:

Step-by-step explanation:

1) 7x^2-5x+10x-8x=7x^2+5x-8x=7x^2-3x

2) -6a^3+5a^3+2a-a=-a^3+2a-a=-a^3+a

3) -4(x+5)-5(x-1)=-4x-20-5x+5=-9x-20+5=-9x-15

4) -a+5b-6a+5(a+1)=-7a+5b+5a+5=-2a+5b+5

5) 18x^4-3x^3-2x^3+x^2-10+6

=18x^4-5x^3+x^2-4

To simplify algebraic expressions, combine like terms, variables and exponents. We simplified five examples, using techniques such as distribution and combining like terms.

To simplify algebraic expressions, one has to combine like terms, which are terms with the same variables and exponents. Here, let's do that:

7x2 – 5x + 10x - 8x simplifies to 7x2 + 5x because -5x + 10x - 8x = 5x.

-6a3 + 5a3 + 2a? - a? simplifies to -a3 + a (assuming the '?' is meant to be a variable).

- 4(x + 5) – 5(x - 1) simplifies first by applying distribution (-4x -20 -5x +5) which then becomes -9x - 15.

-a + 5b - 6a + 5(a + 1) simplifies to -2a + 5b + 5 once you distribute and combine like terms.

18x4 - 3x3 - 2x3 + x2 - 10 + 6 simplifies to 18x4 - 5x3 + x2 - 4 since -3x3 and -2x3 add up to -5x3 and -10 and 6 adds up to -4.

Answer:

28 oz can is the better deal.

Step-by-step explanation:

In order to compare the two, we need to find the unit rate for each can. In this case, the unit rate will be in dollars per oz.

For the 28 oz can,

unit rate = $1.89 ÷ 28 = $0.675 / oz

For the 32 oz can

unit rate = $2.95 ÷ 32 = $0.922 / oz

comparing the unit rates, we can see that the unit rate for the 28 oz can is lower (i.e it costs less per oz for the 28 oz can compared to the 32 oz can)

Hence the 28 oz can is the better deal.

D: None of these are true

Explanation:

If the points on the scatter plot seem to form a line that slants down from left to right, there is a negative relationship or negative correlation between the variables. If the points on the scatter plot seem to be scattered randomly, there is no relationship or no correlation between the variables

To graph 2/5 on a number line, divide the number line into equal segments and locate the point that represents 2/5.

To graph 2/5 on a number line, divide the number line into equal segments and find the point that represents 2/5. Start by labeling the endpoints of the number line with the corresponding values. In this case, you can label 0 on the left and 1 on the right. Since the number line is divided into 5 equal segments, mark the points that correspond to 1/5, 2/5, 3/5, and 4/5 between 0 and 1. Then, locate the point that corresponds to 2/5 and mark it on the number line. Remember to place a dot to represent the point.

In the context of the question, the Y-intercept represents the cost of the tablet that Mio purchased before counting the ongoing costs per month for internet service.

In the context of this problem, the Y-intercept in the graph represents the cost of buying the tablet. Using the algebraic equation for a line, which is y = b + mx, the 'b' term is the Y-intercept. When x (in this case, the number of months) equals zero, y is the initial cost, which serves as our Y-intercept. This is the starting point on the Y-axis, and in the context of Mio's spending, this would be her initial expenditure which is the cost of the tablet itself.

Solve 2y + 3x = 7 and 4x + 3y = 15 by elimination, we get x = -9, y = 17. Multiply and subtract equations to eliminate y, then substitute the result to find x or y.

To solve the system of equations 2y + 3x = 7 and 4x + 3y = 15 using the elimination method, we aim to eliminate one variable to solve for the other. Here's a step-by-step explanation:

The solution for the system of equations is x = -9 and y = 17.

To find the depth of the swimming pool, use the formula for the volume of a rectangular solid and substitute the given values to calculate the depth as 2.5 meters.

The depth of the Olympic-size swimming pool can be calculated using its volume, length, and width.

First, use the formula for the volume of a rectangular solid:

Volume = Length x Width x Depth

4000 = 80 x 20 x Depth

Depth = 4000 / (80 x 20) = 2.5 meters

Depth = 2.5 meters

Answer:

y = 4x + 20

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = 4, thus

y = 4x + c ← is the partial equation

To find c substitute (- 5, 0) into the partial equation

0 = - 20 + c ⇒ c = 0 + 20 = 20

y = 4x + 20 ← equation of line

Answer:

The equivalents are 1/6¹⁰ and  1/6⁸

Step-by-step explanation:

1. Let's recall the rule about the negative exponents to find the equivalents to the expressions provided:

The rule says that any number different than zero, raised to a negative power equals its reciprocal raised to the opposite positive power.

Thus, x ⁻ⁿ = 1/x ⁿ

2. Now, let's find the equivalents after following the rule:

6 ⁻ ¹⁰ = 1 ÷ 6 * 6 * 6 * 6 * 6 * 6 * 6 * 6 * 6 * 6 = 1/6 ¹⁰

6 ⁻ ⁸ = 1 ÷ 6 * 6 * 6 * 6 * 6 * 6 * 6 * 6  = 1/6 ⁸

Answer:

x = 0 , y = 2

Step-by-step explanation:

Solve the following system:

{6 x - 5 y = -10 | (equation 1)

4 x + 3 y = 6 | (equation 2)

Subtract 2/3 × (equation 1) from equation 2:

{6 x - 5 y = -10 | (equation 1)

0 x+(19 y)/3 = 38/3 | (equation 2)

Multiply equation 2 by 3/19:

{6 x - 5 y = -10 | (equation 1)

0 x+y = 2 | (equation 2)

Add 5 × (equation 2) to equation 1:

{6 x+0 y = 0 | (equation 1)

0 x+y = 2 | (equation 2)

Divide equation 1 by 6:

{x+0 y = 0 | (equation 1)

0 x+y = 2 | (equation 2)

Answer:

C) Solution set of{x|X<-3} n {xl x> 5) is an the empty set.

Step-by-step explanation:

Here, the solution set is given as : set of  {x| x < -3 } ∩   {x l x > 5)

Now, defining the each set , we get

{x| x < -3 }   = ( .... -6,-5,-4 ,-3)  = P

and the SET  {x l x > 5} = (5,6,7,........ )  = Q

Now, by taking the intersection of two sets,we get

P ∩ Q = NULL SET as they don not have any element in common.

⇒ {x| x < -3 } ∩   {x l x > 5} is an empty set

Hence, solution set of{x|X<-3} n {xl x> 5) is an the empty set.

Answer:

We rewrite the statement correctly:

 "A linear function has an y-intercept of 12 and a slope of 3/8"

 Therefore, the linear function is:

 y = (3/8) x + 12

 We look for the linear function of the table:

 y-yo = m (x-xo)

 Where,

 m = (y2-y1) / (x2-x1)

 m = ((- 3/8) - (- 3/4)) / ((1/3) - (- 2/3))

 m = ((- 3/8) - (- 6/8)) / (3/3)

 m = ((- 3 + 6) / 8) / (1)

 m = 3/8

 (xo, yo) = (- 2/3, -3/4)

 Substituting:

 y + 3/4 = (3/8) (x + 2/3)

 y = (3/8) x + 2/8 - 3/4

 y = (3/8) x + 1/4 - 3/4

 y = (3/8) x + -2/4

 y = (3/8) x + -1/2

 The lines are:

 y = (3/8) x + 12

 y = (3/8) x + -1/2

Given:

Δ ABC is an Isosceles triangle with AB = CA

   m∠ ABC = ( 6x + 4 )°

   m∠ BAC = 73°

   m∠ BCA = ( 8y - 7 )°

To Find:

x = ?

Solution:

Properties of an Isosceles Triangle.

Here , Δ ABC is an Isosceles triangle with AB = CA

∴  m∠ BAC = m∠ BCA

[tex]73= 8y-7\\8y=73+7\\8y=80\\y=\frac{80}{10} \\y=10[/tex]

∴      m∠ BCA = ( 8y - 7 )°

                       = 8 × 10 - 7

       m∠ BCA  = 73  Which is same as ∠ CAB

Property of a Triangle is Sum of the measures of the angle of a triangle is 180°.

[tex]\angle ACB + \angle CAB + \angle CBA = 180[/tex]

Substituting the values we get,

[tex]73 + 73 + (6x+4) = 180\\6x+4=180-146\\6x=34-4\\6x=30\\x=\frac{30}{6} \\x=5\\[/tex]

The answer is x = 5.
