Find 2x - 3y - z if x = -2, y = 3, and z = -2
Answer:
-11
Step-by-step explanation:
2(-2) - 3(3) - (-2)
4 - 9 (double negative cancels out) + 2
= -13 + 2 = 11
2(x-3)+7=13
What is the answer PLEASE HELP
Answer: 6
Step-by-step explanation:
2(x-3)+7=13
simplify both sides of the equation
(2)(x) + (2)(-3) + 7 = 13 (distribute)
2x + -6 + 7 = 13
(2x) + (-6+7) = 13 (combine like terms)
2x + 1 = 13
subtract 1 from both sides
2x + 1 - 1 = 13 - 1
2x = 12
Divide both sides by two
2x/2 = 12/2
x = 6
The length of Amy's rectangular kitchen is 12 feet. If the area of the room is at least 96 square feet, what is the smallest width the room could have?
The required width of Amy's kitchen would be 8 ft.
Given that,
The measurement of Amy's rectangular kitchen is 12 feet. If the area of the room is at least 96 square feet, To determine the least width the room could have.
The rectangle is a four-sided geometric object with equal-length opposites and 90° angles on each side.
Here,
let the width be x,
according to the question,
area of the kitchen = 96
length × width = 96
12 × x = 96
x = 96 / 12
x = 8
Thus, the required width of Amy's kitchen would be 8 ft.

Maritza remembers her PIN because it is between 1,000 and 1,500 and it is the product of two consecutive prime numbers. What is her PIN
Answer:
The PIN is 1147
Step-by-step explanation:
Prime numbers
These are integer numbers that only divide exactly by themselves and by 1. To find the first possible prime number between 1,000 and 1,500, calculate the square root of 1,000.
[tex]\sqrt{1000}\approx 31.6[/tex]
Thus, the first prime to consider is 31. Write the consecutive primes from 31:
31 , 37 , 41 , 43
We can see the only two consecutive primes whose product lies in the given interval are 31 and 37. Thus, the PIN is 31*37=1147
Krystal won 54 pieces of gum playing
hoops at her school's game night. Later,
she gave two to each of her friends. She
only has 6 remaining. How many friends
does she have?
Please answer!
Answer:
she has 48 friends
Step-by-step explanation:
54-_= 6
Answer:
24
Step 1: Subtract.
Subtract 6 from 54, since she has 6 remaining.
Step 2: Divide by 2.
54 - 6 = 48.
Now divide by 2 to get the answer. You get 24.
The answer is 24. Hope it helps!
A population of sea turtles is growing at a rate of 3% on North Carolina's coast due to great protection
programs on the beaches. If there are currently 3,000 sea turtles, how many years will it take for the
population to double?
Answer:
23.4 years
Step-by-step explanation:
The exponential growth model is
A = P(1 + r)^5t, where r is the annual growth rate as a decimal fraction.
If the original number (P) is to double, then this model becomes
2P = P(1 + 0.03)^t, or 2 = 1.03^t. Solve this for t by taking the log of both sides:
log 2 = t*log 1.03, or
0.30103
t = --------------- = 23.4 years

7k – 7(2 – 6k) = -8k – 14
Answer:
k = 0
Step-by-step explanation:
Step 1:
7k - 7 ( 2 - 6k ) = - 8k - 14 Equation
Step 2:
7k - 14 + 42k = - 8k - 14 Multiply
Step 3:
- 14 + 49k = - 8k - 14 Add
Step 4:
- 14 + 57k = - 14 Add 8k on both sides
Step 5:
57k = 0 Add 14 on both sides
Answer:
k = 0

!!15 POINTS!!What is the domain of the function in this table?
Which equation is correctly rewritten to solve for x?
Answer:
Option (A)
Step-by-step explanation:
Te given equation is,
-qx + p = r
Toe find the value of x,
By subtracting p from both the sides of the equation.
-qx + p - q = r - q
-qx = r - q
By dividing the whole equation by (-q),
[tex]\frac{-qx}{(-q)}=\frac{r-p}{-q}[/tex]
x = [tex]-\frac{r-p}{q}[/tex]
x = [tex]\frac{p-r}{q}[/tex]
Therefore, Option (A) will be the answer.

At a carnival , 7 out of 10 people order a hot dog. If there is 90 people at the carnival, how many of them did
NOT order a hotdog?
Answer:
27 people
Step-by-step explanation:
Out of 10 people, 7 people ordered a hot dog.
Multiply both sides by 9:
Out of 90 people, [tex]7\times9[/tex] people ordered a hot dog.
Thus, 63 people ordered a hot dog.
Number of people who did not order a hot dog: [tex]90-63=27[/tex]

Step-by-step explanation:
if A( 1,8) B(2,6) and C(4,2) are three points, show that AC=3AB
Answer:
see explanation
Step-by-step explanation:
Calculate AC and AB using the distance formula
d = [tex]\sqrt{(x_{2}-x_{1})^2+(y_{2}-y_{1})^2 }[/tex]
with (x₁, y₁ ) = A(1,8) and (x₂, y₂ ) = C(4,2)
AC = [tex]\sqrt{(4-1)^2+(2-8)^2}[/tex]
= [tex]\sqrt{3^2+(-6)^2}[/tex]
= [tex]\sqrt{9+36}[/tex]
= [tex]\sqrt{45}[/tex] = [tex]\sqrt{9(5)}[/tex] = 3[tex]\sqrt{5}[/tex]
Repeat with
(x₁, y₁ ) = A(1, 8) and (x₂, y₂ ) = B(2, 6)
AB = [tex]\sqrt{(2-1)^2+(6-8)^2}[/tex]
= [tex]\sqrt{1^2+(-2)^2}[/tex]
= [tex]\sqrt{1+4}[/tex]
= [tex]\sqrt{5}[/tex]
So AB = [tex]\sqrt{5}[/tex] and AC = 3[tex]\sqrt{5}[/tex]
Thus
AC = 3AB
Answer:
Proven below
Step-by-step explanation:
Distance Between Points in the Plane
Given two points A(x,y) and B(w,z), the distance between them is:
[tex]d=\sqrt{(w-x)^2+(z-y)^2}[/tex]
Let's calculate the distance AC, where A(1,8) and C(4,2):
[tex]d_{AC}=\sqrt{(4-1)^2+(2-8)^2}[/tex]
[tex]d_{AC}=\sqrt{3^2+(-6)^2}[/tex]
[tex]d_{AC}=\sqrt{9+36}=\sqrt{45}[/tex]
Since 45=9*5:
[tex]d_{AC}=\sqrt{9*5}=3\sqrt{5}[/tex]
Calculate the distance AB, where A(1,8) and B(2,6)
[tex]d_{AB}=\sqrt{(2-1)^2+(6-8)^2}[/tex]
[tex]d_{AB}=\sqrt{1^2+(-2)^2}[/tex]
[tex]d_{AB}=\sqrt{1+4}=\sqrt{5}[/tex]
It follows that:
[tex]d_{AC}=3d_{AB}[/tex]

Answer:
95°85°Step-by-step explanation:
Given angles are consecutive interior angles which sum up to 180°
9x + 14 + 8x + 13 = 18017x = 180 - 2717x = 153x = 153/17x = 9Angles
9x + 14 = 9*9 + 14 = 81 + 14 = 95°8x + 13 = 85°-2x +5y= -15
