Answer:
Step-by-step explanation:
(3,2),(-9,6)
slope = (6 - 2) / (-9 - 3) = -4/12 = -1/3
y = mx + b
slope(m) = -1/3
use either of ur points...(3,2)....x = 3 and y = 2
now we sub into the formula and find b, the y int
2 = -1/3(3) + b
2 = -1 + b
2 + 1 = b
3 = b
so ur equation is : y = -1/3x + 3 <==

Josefina fue al banco para cambiar un cheque de $5000. La cajera le entregó 39
billetes, unos eran de $100 y otros de $200; ¿Cuántos billetes de $100 y cuantos de
$200 recibió Josefina?
Respuesta: 28 billetes de 100 y 11 billetes de 200
Explicación paso a paso:
X=39-y
200(39-y)+100y=5000
7800-200x+100y=5000
-100y=2800
Y=2800/100
Y=28 billetes de 100
X=39-28
X=11 billetes de 200
Solve the equation. n/10+8=15
Answer:
n = 70
Step-by-step explanation:
n/10 + 8 = 15
n + 80 = 150
n = 150 - 80
n = 70
Answer:
n = 70
Step-by-step explanation:
1) Subtract 8 from both sides of the equation
n/10 + 8 - 8 = 15 - 8
2) Simplify
n/10 = 7
3) Multiply all terms by the same value to eliminate fraction denominators
10 · n/10 = 10 · 7
4) Simplify
n = 70
so your answer is n = 70. Hope that helps!
a) Dati cinci exemple de numere intregi mai mici ca zero.
Answer:
Numerele întregi pozitive sunt toate numerele întregi mai mari decât zero: 1, 2, 3, 4, 5, .... Numere întregi negative sunt toate opusele acestor numere întregi: -1, -2, -3, -4, -5, .... Nu considerăm că zero este un număr pozitiv sau negativ. Pentru fiecare număr întreg pozitiv, există un număr întreg negativ, iar acești numere întregi se numesc opuse. De exemplu, -3 este opusul lui 3, -21 este opusul lui 21 și 8 este opusul lui -8. Dacă un număr întreg este mai mare decât zero, spunem că semnul său este pozitiv. Dacă un număr întreg este mai mic decât zero, spunem că semnul său este negativ.

Given the linear equation & its graph, what is the slope?
Answer:
Slope: 5/3
Step-by-step explanation:
Linear equation:
y = mx + b
m is the slope
so if,
y = 5/3x - 4
5/3 is the slope.

Complementary angles
Find the value of x in each right angle.
I cannot get this wrong
Answer:
The value of x = 28°
Step-by-step explanation:
Explanation:-
Complementary angles:-
Two angles are called Complementary angles when their measures add to 90 degrees
∠A + ∠B = 90°
(x+40)° + 22° = 90°
x + 62° = 90°
x = 90 - 62
x = 28°
Find the perimeter of a square with side lengths of 3x + 1. Use the distributive property to write an expression.
Simplify the expression below.
12a−8−5a+12
Step-by-step explanation:
Given
12a - 8 - 5a + 12
= 7a + 4
Hope it will help :)
Answer:
7a + 4
Step-by-step explanation:
First, let's rewrite this expression to combine like terms:
12a – 8 – 5a + 12 — I bolded the constants and underlined the expressions with variables
12a – 5a – 8 + 12 — it looks a little easier regrouped, doesn't it?
The last two terms are easy, right?
12 – 8 = 4 — simplify with subtraction
We'll focus on the first two terms now. Let's rewrite the terms with variables attached to make the subtraction easier:
a(12 – 5) = a(7) = 7a
We could also think of it this way: multiplication is just repeated addition.
12a = a + a + a + a + a + a + a + a + a + a + a + a (we just add a to itself 12 times)
5a = a + a + a + a + a (we just add a to itself 5 times)
Subtracting this expression would then look like this:
a + a + a + a + a + a + a + a + a + a + a + a – (a + a + a + a + a)
a + a + a + a + a + a + a + a + a + a + a + a – a – a – a – a – a
Five of the a values will cancel out, and to show this, we can rewrite the expression once more, like this:
a – a + a – a + a – a + a – a + a – a + a + a + a + a + a + a + a
The five a values cancel out and leave us with this:
a + a + a + a + a + a + a
How many a values are added together now? Seven of them, right? We add a to itself 7 times. We can then rewrite that expression as 7a.
Using the [12 – 8 = 4] expression from above, we add the 4 to the 7a to find our final answer: 7a + 4
I hope this helps increase your understanding of the concept! Have a great day!

Anosh collects feathers. His father started his collection by giving him 7
feathers. Since then he has collected 28 more feathers. How many feathers does
Anosh have?
Answer:
Anosh has 35 feathers.
Step-by-step explanation:
Initially, he had 0 feathers.
His father started his collection by giving him 7 feathers.
After his father gave him, he has 7 feathers.
Since then he has collected 28 more feathers. How many feathers does Anosh have?
So now, he has 7 + 28 = 35 feathers.
Anosh has 35 feathers.

Find the quotient when x + 11x + 18 is divided by
x +9
Answer:
(12x + 18)/(x+9)
Step-by-step explanation:
We have: (x + 11x + 18)/(x+9). First simplify this equation by adding like terms.
(12x + 18)/(x+9), which is your answer. This is the final answer because we can't simplify this expression anymore.

Hey there!
The answer is √20 or approximately 4.47
We can use the Pythagoreon Theorem, which is [tex]a^2 +b^2=c^2[/tex]. [tex]a[/tex] and [tex]b[/tex] are the names of the two sides, and [tex]c[/tex] is the name of the hypotenuse leg, or the longest side. We will plug the numbers into the formula, and solve:
[tex]2^2+4^2=c^2\\4+16=c^2\\20=c^2\\4.47...=c[/tex]

Hi there!
[tex]\large\boxed{x < 2}[/tex]
[tex]\frac{4x + 6}{7} < 2[/tex]
Begin by multiplying both sides by 7:
[tex]4x + 6 < 2 * 7 \\\\4x + 6 < 14[/tex]
Subtract 6 from both sides to isolate for x:
[tex]4x + 6 - 6 < 14 - 6\\\\4x < 8[/tex]
Divide both sides by 4 to solve for x:
[tex]4x/4 < 8/4\\\\x < 2[/tex]

There are 22 third-graders in Sally's town. If there are 4 more boys than girls, how many girls are there?
Answer:
22-4=18
Step-by-step explanation:
Answer:
9 girls
Step-by-step explanation:
First we know from the information there are 22 kids in total.
Next we know 11+11=22 so one number would be 2 more than the other.
So 13+9=22
Therefore, there is 9 girls in Sally's town.

Answer:
perimeter is 34 cm
Step-by-step explanation:
Notice you need to find the value of two sides whose measure is not given. The first one is horizontal and 10 cm - 4 cm = 6 cm in length
The second one is vertical with a measure of 7 cm - 4 cm = 3 cm
Then, the addition of all sides going clockwise becomes:
7 + 10 + 4 + 6 + 3 + 4 = 34 cm
