The value of c is 9 makes the equation true.
It is given that the equation 12 - 9 + c =12.
It is required to find the value of c that makes the equation true.
What is a linear equation?It is defined as the relation between two variables if we plot the graph of the linear equation we will get a straight line.
If in the linear equation one variable is present then the equation is known as the linear equation in one variable.
We have a linear equation in one variable:
12 - 9 + c = 12
-9 + c =0 (subtract 12 on both sides)
c = 9 ( add 9 on both sides)
Thus, the value of c is 9 makes the equation true.

Answer:
see explanation
Step-by-step explanation:
Since AC = BC then ΔABC is isosceles with base angles
∠BAC =∠ABC, thus
3x + x = 70
4x = 70 ( divide both sides by 4 )
x = 17.5
----------------------------------------------------
∠ADC is an external angle of ΔABD and the external angle is equal to the 2 opposite interior angles, hence
y = 70 + x = 70 + 17.5 = 87.5

Answer:
[tex]d\geq 5\\\\w<7\\\\a\leq 4[/tex]
Step-by-step explanation:
For each you have to look at three things - the direction of the arrow, if the circle is filled in, and the number the point is located on.
If the arrow is pointed right and the numbers are increasing, you use the greater than sign (>).
If the arrow is pointed left and the numbers are decreasing, you use the less than sign (<).
If the circle is filled in, it means you use the greater than or equal to (≥) less than or equal to signs (≤).
For the first inequality, the arrow is pointing right, the circle is filled in, and the point is on five so the inequality is [tex]d\geq 5[/tex].
For the second inequality, the arrow is pointing left, the circle is not filled in, and the point is on seven so the inequality is [tex]w<7[/tex].
For the third inequality, the arrow is pointing left, the circle is filled in, and the point is on four so the inequality is [tex]a\leq 4[/tex].

a reflecting pool is shaped like a right triangle with one leg along the wall of a building. the hypotenuse is 9 feet longer than the side along the building. the third side is 7 feet longer than the side along the building. find the length of all three sides of the reflecting pool
Answer: The length of all three sides of the reflecting pool are 8 feet , 17 feet and 16 feet.
Step-by-step explanation:
Let sides along the building be 'x', then the measure of hypotenuse = x+9 and the measure of third side = 7+x
Since , the reflecting pool is shaped like a right triangle.
Then , by using Pythagoras theorem , we have
[tex](x+9)^2=x^2+(x+7)^2\\\\\Rightarrow\ x^2+81+18x=x^2+x^2+49+14x\ \ [\text{Using }(a+b)^2=a^2+b^2+2ab ]]\\\\\Rightarrow\ x^2+81+18x=2x^2+49+14x\\\\\Rightarrow\ x^2-4x-32=0\\\\\Rightarrow\ x^2-8x+4x-32=0\\\\\Rigtarrow\ x(x-8)+4(x-8)=(x-8)(x+4)\\\\\Rightarrow\ x=8\ or -4[/tex]
But length cannot be negative , it means x= 8
Now, the length of side along building = 8 feet
Length of hypotenuse = 9+8 =17 feet
Length of third side = 8+7= 16 feet
Final answer:
Using the Pythagorean Theorem and setting the length of the side along the building as x, we solve the quadratic equation to find that the side along the building is 8 feet, the third side is 15 feet, and the hypotenuse is 17 feet.
Explanation:
To solve for the lengths of all three sides of the reflecting pool, we can use the Pythagorean Theorem, which states that in a right triangle, the square of the hypotenuse (c) is equal to the sum of the squares of the other two legs (a and b). Let's denote the length of the side along the building as x. Therefore, the hypotenuse will be x + 9 feet and the third side will be x + 7 feet. The equation can be set up as follows:
x² + (x + 7)² = (x + 9)²
Expanding the squares and solving for x gives us:
x² + x² + 14x + 49 = x² + 18x + 81
Combine like terms and move everything to one side:
x² + 14x + 49 - 18x - 81 = 0
x² - 4x - 32 = 0
Factoring the quadratic equation:
(x - 8)(x + 4) = 0
Since a length cannot be negative, we take the positive solution x = 8 feet. Now we can find the lengths of each side:
Side along the building: 8 feet
Third side (7 feet longer than the side along the building): 8 + 7 = 15 feet
Hypotenuse (9 feet longer than the side along the building): 8 + 9 = 17 feet

We assume you're describing a geometric sequence with first term m and common ratio 2. Then the n-th term is ...
a[n] = m·2^(n-1)
and the fourth term is
a[4] = m·2^(4-1) = 8m
What is
A= 3000(1+.036/12)^72

First we need to simplify [tex]\frac{.036}{12}[/tex] to 0.003.
We get 3000(1+0.003)[tex]^{72}[/tex]
Now we simplify 1+0.0031+0.003 to 1.0031.003.
3000×1.00[tex]3^{72}[/tex]
Simplify {1.003}^{72}1.003 to 1.2407011.240701.
3000×1.240701
Then we simplify to 3722.103387.

Answer:
Third option
x ≠2 and x cannot be any value for which v(x) = 0
Step-by-step explanation:
In this problem we are asked to find the domain of the function
[tex](UoV)(x)[/tex]
We know that [tex](UoV)(x) = U(V(x))[/tex].
We know that:
Domain of U(x) is all real numbers except x = 0
Domain of V(x) is all real numbers except x = 2.
Then the domain of the composite function U(V (x)) is:
all real numbers except x = 2. (since x = 2 does not belong to the domain of V(x) and all values of x for which V(x) = 0 (since x = 0 does not belong to the domain of U(x))
Finally the domain of [tex](UoV)(x)[/tex]) is:
[tex]x \neq 2[/tex] and [tex]V(x) \neq 0[/tex]

What is the end point of a ray?
Answer:
A ray is a part of a line that has one endpoint and goes on infinitely in only one direction you can't measure the length of a ray ..hope this helps
Step-by-step explanation:
The endpoint of a ray is the starting point from which the ray extends indefinitely in one direction. It's different from a line, which has no endpoint as it extends indefinitely in both directions.
Explanation:In mathematics, specifically in geometry, a ray is a part of a line that starts at a particular point, known as the initial point, origin, or endpoint, and extends indefinitely in one direction. This is different from a line, which extends in both directions. When you draw a ray, you put an arrow on one end to show that it continues without end in that direction. The
end point of a ray is essentially the starting point from which the ray extends. For example, if you have a ray AB, point A is the endpoint and the ray extends towards point B but beyond it indefinitely. Thus, a ray has only one endpoint, not two.

The zeros of a quadratic function are -8 and 5. Write the quadratic function in Standard Form.
Answer:
y = x² + 3x - 40
Step-by-step explanation:
Given the zeros are x = - 8 and x = 5, then the factors are
(x + 8) and (x - 5) and
y = (x + 8)(x - 5) ← expand factors
y = x² - 5x + 8x - 40, hence
y = x² + 3x - 40 ← in standard form
the graph of f(x)=(c) is translated 6 units to the right and 2 units up to form a new function
Answer:
Step-by-step explanation:
My opinion is that you meant "f(x) = c." This would be a constant function whose graph is a horizontal line, y = c.
If this graph were translated 6 units to the right, the function would not change.
However, if this function f(x) = c were translated 2 units up, the new function would be g(x) = c + 2.
Here’s a graph of a linear function. Write the equation that describes that function ??
Answer:
The equation of the line is y = x + 1
Step-by-step explanation:
In order to find this, start with two points that are on the line. We'll use (0, 1) and (1, 2). Now we can use the slope formula to find the slope.
m(slope) = (y2 - y1)/(x2 - x1)
m = (2 - 1)/(1 - 0)
m = 1/1
m = 1
Now that we have this, we can use that slope and a point in point-slope form. Then we solve for y to get the equation.
y - y1 = m(x - x1)
y - 1 = 1(x - 0)
y - 1 = 1x
y = 1x + 1

Answer:
528
Step-by-step explanation:
x = 480
1.1 x = 480 * 1.1
480 + 48 = 528
Timothy traveled 528 miles using the gasoline from Smith's Station, which is 10% farther than the 480 miles he traveled with gasoline from Jack's Station.
Explanation:To calculate how far Timothy traveled using the gasoline from Smith's Station, we need to determine what 10% more than the 480 miles he traveled using gasoline from Jack's Station is. First, let's find 10% of 480 miles:
10% of 480 miles = 0.10 × 480 miles = 48 miles.Now, let's add this additional distance to the original 480 miles to find the total distance traveled with gas from Smith's Station:
480 miles + 48 miles = 528 miles.Therefore, Timothy traveled 528 miles on a tank of gas from Smith's Station.
