Answer:
x=2, y=8 or (2, 8)
Step-by-step explanation:
y=3x+2
y=7x-6
substitute y=7x-6 into y=3x+2
7x-6=3x+2
4x=8
x=2
then plug 2 into either one
y=7(2)-6
y=8

Step-by-step explanation:
Celia writes the addition problem shown.she says she can tell which sum will be greater without adding.how does she know?
The sum of 5157 + 519 will be greater because she knows that 519 > 364.
What is summation?A summation, also abbreviated as a sum, is the outcome of adding two or more numbers or quantities. Here are always an integer number of terms in a summation. There could be only two terms, but there could be one hundred, thousand, or a million. There are summations with an infinite set of parameters.
In another word, the summation is to add or subtract any two or more terms by doing that operation we will get a new result which could be big or small depending upon the number.
Let's say two sum
x + y and x + z
If we want to calculate which is bigger then we need to look to y and z since x is common in both.
If y > z then x + y will be bigger and if z > y then x + z will be bigger.
Given the sum,
8157 + 364 and 8157 + 519
Now since 519 > 364 so (8157 + 519 ) > (8157 + 364)
Hence "The sum of 5157 + 519 will be greater because she knows that 519 > 364".

For how many different pairs of positive integers (a,b) with greatest common factor 1, and with a>b, does ab=30!
Answer:
4 pairs
Step-by-step explanation:
Given
ab = 30
Where
a > b
Required
Determine number of pairs (a,b)
To do this, we simply test values for a and b that satisfy the required condition.
First,
Take a = 30
Substitute 30 for a in ab = 30
30 * b = 30
b = 30/30
b = 1
The pair is (30,1)
Take a = 15
Substitute 15 for a in ab = 30
15 * b = 30
b = 30/15
b = 2
The pair is (15,2)
Take a = 10
Substitute 10 for a in ab = 30
10 * b = 30
b = 30/10
b = 3
The pair is (10,3)
Take a = 6
Substitute 6 for a in ab = 30
6 * b = 30
b = 30/6
b = 5
The pair is (6,5)
There exist no other pair that satisfy the given condition.
Counting the above pairs, there are just 4 pairs.

a phone company advertises a new plan in which the customer pays a fixed amount of $25 per month for unlimited calls in the country and $0.10 per minute for international calls. if a costumer uses 65 international minutes, how much do they owe?
Answer:
$31.50
Step-by-step explanation:
To solve this problem, create the equation
y = 0.10x + 25
Where x is equal to the number of international minutes and y is equaled to the total price paid. Since we are give the number of international minutes (the x), plug this into the equation and solve for y.
y = 0.10(65) + 25
y = 6.5 + 25
y = 31.5 or $31.50
P=$4130,r=?,t=155 days, I=$115.58
Answer:
r = 6.5902%
Step-by-step explanation:
I = Prt
since the time is in days, it needs to be converted to years.
t = 155/365 = 0.424658
115.58 = (4130) r (0.424658)
115.58 = 1753.8045 r
115.58/1753.8054 = r
0.065902 = r
then, converting r decimal to a percentage
r = 0.065902 x 100 = 6.5902 %

Terry is trying to place a satellite dish on the roof of his house at the recommended height of 18 feet. His house is 32 feet wide, and the height of the roof can be described by the function below,where x is the distance along the width of the house. Where should Terry place the dish? h(x) = -3/2 | x - 16 | + 24 A: No place is high enough B: Right at top C: 12 or 20 feet from the edge D: 4 or 28 feet from the edge
Answer:
C: 12 or 20 feet from the edge
Step-by-step explanation:
We are told the recommended height is 18 feet and that the function describing the height is;
h(x) = -(3/2)|x - 16| + 24
This means that;
-(3/2)|x - 16| + 24 = 18
Multiply through by -2/3 to give;
|x - 16| + 24(-2/3) = 18(-2/3)
|x - 16| - 16 = -12
Add 16 to both sides to get;
|x - 16| = 16 - 12
|x - 16| = 4
Add 16 to both sides to get;
Expanding the absolute value problem, we have;
x - 16 = 4 or -(x - 16) = 4
Thus;
x = 16 + 4 or -x + 16 = 4
x = 20 or x = 16 - 4
x = 20 or x = 12
Since x is the distance along the width of the house, then Terry should place the dish 12 or 20 feet from the edge
find the two angle measures from the diagram 3x+10 3x-28 there's 3 answer's 71,71 109 ,109 109,71 last question brainiest u will get
Answer:
109 and 71Step-by-step explanation:
3x + 10 + 3x - 28 = 180
6x = 180 - 10 + 28
x = 198/6
x = 33
substitute the value of x = 33 back into the equation to solve for each angle
= 3x + 10
= 3(33) + 10
= 109
= 3x - 28
= 3(33) - 28

In 1998, the population of country C was 38 million, and the exponential growth rate was 1% per year
Answer:
Step-by-step explanation:
Formula for the exponential graph is given by the function,
[tex]P(t) = P_0(1 + r)^t[/tex]
Where [tex]P(t)[/tex] = population after 't' years
[tex]P_0[/tex] = Initial population
r = rate of increase
t = Number of years
In 1988, population of a country C was 30 million.
A). Function for the population will be,
[tex]P(t)=38(1+0.01)^t[/tex]
[tex]=38(1.01)^t[/tex]
B). Population in year 2020,
[tex]P(22)=38(1.01)^{22}[/tex]
= 47.30 million
C). Doubling time means the duration in which [tex]P_0[/tex] becomes [tex]2(P_0)[/tex].
[tex]P(t)=2P_0[/tex]
[tex]2P_0=P_0(1.01)^t[/tex]
[tex](1.01)^t=2[/tex]
By taking log on both the sides of the equation,
t[log(1.01)] = log2
t = [tex]\frac{\text{log}(2)}{\text{log}(1.01)}[/tex]
= [tex]\frac{0.30103}{0.004321}[/tex]
t = 69.66 years

What is the y intercept of the line represented by the equation
3x+2y = 6?
Answer:
3
Step-by-step explanation:
To identify the y-intercept represented by the given equation, we need to get the equation into slope-intercept from:
[tex]y=mx+b[/tex]
[tex]m=slope[/tex]
[tex]b=y-intercept[/tex]
Start with:
[tex]3x+2y=6[/tex]
Subtract [tex]3x[/tex] from both sides of the equation:
[tex]2y=-3x+6[/tex]
Divide both sides of the equation by the coefficient of [tex]y[/tex], which is [tex]2[/tex]:
[tex]y=-1.5x+3[/tex]
Identify the y-intercept:
[tex]b=3[/tex]
The diameter of a semicircle is 10 feet what is the semicircle radius
Answer:
the radius is 5 ft.
Step-by-step explanation:
radius = 1/2 diameter
10/2 = 5
R= 5
Answer: 5 feet
This one is easy. Because the radius of a circle (or a semicircle) is half of the diameter, you can simply divide the diameter by 2.

What is the area of a triangle if the top is 3 the left side is 6 and the right side is 6.7
the answer is 120.6 I'm pretty sure
Answer:
9.525 units squared
Step-by-step explanation:
I'm assuming the 3 is the base of the triangle so I split 3 in half and got 1.5 for 2 right triangles. I then did the area of a right triangle formula 1/2 base x height
1/2(1.5 x 6)=4.5
1/2(1.5 x 6.7) =5.025
Add these two together
5.025+4.5=9.525

Solve: -4 (x + 6) + 2 ( x -2) Show your work
Answer:
-2x - 28
Step-by-step explanation:
-4(x+6) +2 (x-2) Distribute the -4 to (x+6) and the 2 to (x-2):
-4x - 24 + 2x - 4 Combine like terms -4 + 2x and -24-4:
-2x - 28
Hope this helped :)
Answer:
Please see explanation.
Step-by-step explanation:
-4(x+6) + 2(x-2) First, distribute the -4 to x+6
-4x - 24 + 2(x-2) Now distribute the 2 into x-2
-4x - 24 + 2x - 4 Combine like terms
-4x + 2x - 24 - 4
-2x - 28 This might be your answer but if you are looking for what x is equal to then keep following along.
If you are solving for x then most likely the equation says that it is equal to zero
-2x - 28 = 0 Add 28 to both sides
-2x = 28 divide both sides by -2
x = -14
