One number is 9 more than twice the other number. Their sum is 54. Find the numbers.

Answer:

y = -7x + 2

Step-by-step explanation:

in the general equation y = ax + b, a is the slope and b is the y coordinate of the y intercept.

Answer:

y=-7x+2

Step-by-step explanation:

The equation is represented by y=mx+b where m is slope and b is the y-intercept.

Answer:

(-4,-5)

Step-by-step explanation:

1. Image is the points after the transformation

2. Pre-Image is the original points

3. our x value is left to right and our y value is up and down (x,y)

4. Our points are (-4,2)

5. They first want us to translate three units up, so we add to our y value (y is up and down)

6. 2+3 = 5

7. Our new points are (-4,5)

6. Now we are asked to reflect over the x axis. Remember their are a lot of rules concerning reflections. For a reflection across x-axis our equation is this : (x,y) → (x,-y)

7. (-4,5) → (-4,-5)

8. (-4,-5) is our answer

Answer:

Tommie planted the most.

Tommie plants twice that amount, and Tommie plants more rows of pepper plants.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Alethea plants 3 rows of carrots for every 1 row of pepper plants.

And, Alethea plants 9 rows of carrots and Tommie plants twice that amount.

Here, Alethea plants 9 rows of carrots and Tommie plants twice that amount.

So, We get;

Tommie plants twice that amount, and Tommie plants more rows of pepper plants.

Step-by-step explanation:

H0 : µ ≤ 26.9

Ha : µ > 26.9

a. since the null hypothesis is rejected, we would accept the alternative hypothesis and come to the conclusion that there is enough evidence that beer and cider consumption are higher than 26.9 in the city.

b. type 1 error happens when we reject a true null hypothesis.

this error error in this question would be that our conclusion that beer and cider consumption is greater than 26.9 is not true. what is true is that it is equal to or less than 26.9.

the consequence is that is h0 is false it would be harder to reject it at a lower level of significance.

c. type ii error happens when the null hypothesis is accepted even though it is false. here, error would be that cider we accepted that cider and beer consumption is less than or equal to 26.9 when it is actually greater than 26.9

the consequence is that it would be harder to accept a true h0 at a high level of significance

Answer:

144

Step-by-step explanation:

1. Rewrite question since you know the variable. Rewritten it would be 4×3^2

2. Do multiplication. 4 times 3 is 12

3. Square 12 which means 12 times 12

4. 12 times 12 is 144.

Hopefully it's right!

Answer:

A is 13

B is 5

C is 0.25

And D is 4.58 or 4.6

Good Luck!

Answer:

A) 0.2 + 7.9 + 3.8 + 1.1 = 13

B) -5.6 + 5 + 4.6 + 1 = 5

C) 3 1/6 - 4 3/4 + 1 5/6 = 1/4

D) 2 1/12 + 3 1/6 - 1 1/12 = 4 1/6

Step-by-step explanation:

A) 0.2 + 3.8 = 4... 7.9 + 1.1 = 9... 4 + 9 = 13

B) 4.6 + 1 = 5.6... 5.6 - 5.6 = 0... 0 + 5 = 5

C) 3 1/6 + 1 5/6 = 5. 5 - 4 3/4 = 1/4

D) 2 1/12 - 1 1/12 = 1. 1 + 3 1/6 = 4 1/6

Answer: (-4,-7)

Step-by-step explanation:

The Midpiont formale is in the picture and add -6 with -2 and add -8 with -6.

-6 + -2 = -8

-8+-6=-14

-8 divided 2 = -4

-14 divided 2 = -7

(-4,-7)

Answer:

No

Step-by-step explanation:

So if the director paid $90 for 12 visors, we need to find how much one cost so 90/12 = 7.5

Then to find the cost of 15 visors, multiply 7.5 by 15 to get 112.5

now add 112.5 to 90 to see if it stays within the budget of $200, 112.5 + 90 = 202.5, so NO there is not enough money in the budget to buy 15 more sun visors.

Answer:

[tex]T > 45[/tex]

Step-by-step explanation:

Given

[tex]\frac{T}{3} > 15[/tex]

Required

Graph the solution

[tex]\frac{T}{3} > 15[/tex]

Multiply both sides by 3

[tex]3 * \frac{T}{3} > 15*3[/tex]

[tex]T > 15*3[/tex]

[tex]T > 45[/tex]

Answer:

The area of the photograph is:  [tex]A=x^2-4[/tex]      

Step-by-step explanation:

Given

The length of rectangular photograph = [tex]l[/tex] = (x + 2) inches

The width of rectangular photograph = [tex]w[/tex] = (x - 2) inches

To determine

The area of the photograph

Important Tip:

Given that the photograph is in the shape of a rectangle. Thus, we can use the formula involving the area of a rectangle to determine the area of a photograph.

The Area of the photograph can be determined using the formula

[tex]A = wl[/tex]

where

now substituting [tex]l = (x + 2)[/tex] and [tex]w = (x-2)[/tex] in the formula

[tex]A = wl[/tex]

[tex]A = (x-2) (x+2)[/tex]

Apply Difference of Two Squares Formula:  [tex]\left(a-b\right)\left(a+b\right)=a^2-b^2[/tex]

[tex]A=x^2-2^2[/tex]       ∵ [tex]a=x,\:b=2[/tex]

[tex]A=x^2-4[/tex]        ∵ [tex]2^2=4[/tex]

Therefore, the area of the photograph is:  [tex]A=x^2-4[/tex]

Hello your question is incomplete attached below is the complete question

answer: RS = ST ( option b )

Step-by-step explanation:

First we consider Δ SCA and Δ TCB

∠ SCA  = ∠ TCB  ,  ∠CAS = ∠CBT = 90°

if we assume  RS = ST then ΔSRT will be termed an Isosceles triangle with its legs : SR = ST. also vertex S bisects the base of the triangle.

Δ SBR ≅ ΔSBT  from here we can deduce that ; BR = BT

From the assumptions what is actually missing to contrast the proof is : RS = ST
