Study the equations:
f(x) = 6x + 7
g(x) = 4x – 2
What is h(x) = f(x)g(x)?
h(x) = 24x2 – 14
h(x) = 24x2 + 40x + 14
h(x) = 24x2 + 16x – 14
h(x) = 24x2 + 12x – 14
Answer:
h(x)=24X^2+40x+14

Answer:
answer is 45 add all angle=360 it make 360/8
Answer:
x = 45
Step-by-step explanation:
The 2 interior angles of the triangle adjacent to both 3x's is
180 - 3x
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
2x is an exterior angle of the triangle, thus
180 - 3x + 180 - 3x = 2x , that is
360 - 6x = 2x ( add 6x to both sides )
360 = 8x ( divide both sides by 8 )
45 = x
A manufacturer can produce 1554 parts in 7 hours. What is the unit rate in parts per hour?
Answer: 222 parts per hour
Step-by-step explanation: To find how many parts a manufacturer Can produce in 1 hour if it can produce 1,554 parts in 7 hours, then look for the unit rate. (1,554/7) To do this, simply divide 1,554 by 7, which gives you a final answer or result of 222. Hence, a manufacturer can produce 222 parts in 1 hour.
Unit Rate: 222/1Answer:
222 parts
Step-by-step explanation:
1554 divided by 7 is 22.

Two lengths of a triangle are 14 and 17. What is the largest
possible whole number perimeter?
If two lengths of a triangle are 14 and 17. Then the largest possible whole number perimeter is 62.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
Two lengths of a triangle are 14 and 17.
Side one is fourteen and side two is seventeen.
First we need to find the largest third side
The third side should always be less than the sum of other two sides lengths.
14+17
31
The third side must be less than 31, the largest possible third side is 30
Now let us find the perimeter of triangle.
Perimeter=14+17+31
=62
Hence the largest possible whole number perimeter is 62.

The graph shows the savings in Andre’s bank account.
Answer:
As the number of week increases, the Andre's savings also increases
Step-by-step explanation:
Given
The attached graph
Required
Explain what the slope represents (Missing part of the question:)
First, we'll check the slope of the graph.
Represent time in weeks with x and savings in dollar with y
So, we have the following details:
[tex](x_1,y_1) = (0,40)[/tex]
[tex](x_2,y_2) = (8,80)[/tex]
Slope (m) is then calculated as thus:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{80 - 40}{8 - 0}[/tex]
[tex]m = \frac{40}{8}[/tex]
[tex]m = 5[/tex]
The calculated slope is positive and this implies that: As the number of week increases, the Andre's savings also increases

Step-by-step explanation:
-3x + 2y = 56
-5x - 2y= 24
Answer:
x = -10 and y = 33
Step-by-step explanation:
just plug them in for x and y, you'll see that they're correct
Answer:
(- 10, 13 )
Step-by-step explanation:
Given the 2 equations
- 3x + 2y = 56 → (1)
- 5x - 2y = 24 → (2)
Adding the 2 equations term by term eliminates the y- term, that is
- 8x = 80 ( divide both sides by - 8 )
x = - 10
Substitute x = - 10 into either of the 2 equations and solve for y
Substituting into (1)
- 3(- 10) + 2y = 56
30 + 2y = 56 ( subtract 30 from both sides )
2y = 26 ( divide both sides by 2 )
y = 13
Solution is (- 10, 13 )

Step-by-step explanation:
The town of gettysburg, PA, plans to shoot a live cannon as part of their annual Gettysburg Civil War Battle Reenactment. The organizers want to make sure that when they fire the cannon, it lands in a location that does not injure any participants or spectators. The slope of the field they are firing into can be represented by the equation y=0.15x. Let x represent horizontal distance, and y represents vertical distance.. if the cannon fires the cannon ball at an arc denoted by the equation y=-0.5x^2+2.5x+1, at what distance will the cannonball land.
-I know i'm supposed to set -0.5x^2+2.5x+1=.15x and use distance formula BUT I KEEP GETTING DIFFERENT ANSWERS.
Answer:
The cannonball lands at approximately 5.093 unit distance from the point of fire
Step-by-step explanation:
The given parameters are;
The arc denoting the equation of motion of the cannon is y₁ = -0.5·x² + 2.5·x + 1
The slope of the field where in the direction the cannon is fired is y₂ = 1.5·x
The points where the cannonball land on the slopping field is given as rightly pointed by equating the two equations, the cannonball path path and the field path as follows;
At the point of contact of the cannonball and the field, the y-values of both equation will be equal
y₁ = y₂
∴ -0.5·x² + 2.5·x + 1 = 0.15·x
Which gives;
-0.5·x² + 2.5·x - 0.15·x + 1 = 0
-0.5·x² + 2.35·x + 1 = 0
-(-0.5·x² + 2.35·x + 1) = 0.5·x² - 2.35·x - 1 = 0
0.5·x² - 2.35·x - 1 = 0
The above equation is in the general form of a quadratic equation, which is given as follows;
a·x² + b·x + c = 0
By the quadratic equation, we have;
[tex]x = \dfrac{-b\pm \sqrt{b^{2}-4\cdot a\cdot c}}{2\cdot a}[/tex]
Plugging in the values, gives;
[tex]x = \dfrac{2.35\pm \sqrt{(2.35)^{2}-4\cdot (0.5)\times (-1)}}{2\cdot (0.5)} = \dfrac{2.35\pm \sqrt{7.5225}}{1} =2.35 \pm \sqrt{7.5225}[/tex]
∴ x ≈ 5.093 or x ≈ -0.393
Therefore, the cannonball will takeoff at x ≈ -0.393 and land at x ≈ 5.093
The height from which they fire the cannon is given by the substituting the value of x ≈ -0.393 into the equation for the path of the cannonball, to give;
[tex]y_{(initial)}[/tex] = -0.5·(-0.393)² + 2.5·(-0.393) + 1 = -0.0597
[tex]y_{(initial)}[/tex] ≈ -0.0597.
However, the actual initial height from which the cannonball is fired given by placing x = 0, which gives y = 1, which is the reason for the other (negative) value for x. Please see the attached graph created with Microsoft Excel.
