Answer:
[tex]\frac{3x+7}{x+2}[/tex]
Step-by-step explanation:
Given the following question:
[tex]\frac{(x+4)(3x+7)}{(x+4)(x+2) }[/tex]
In order to simplify the expression given we can only cancel the common factor which is four.
[tex]\frac{(x+4)(3x+7)}{(x+4)(x+2) }[/tex]
[tex]cf=(x+4)[/tex]
[tex]\frac{x+4}{x+4}[/tex]
[tex]=\frac{3x+7}{x+2}[/tex]
Cannot be simplified further due to it not having any more common factors. Your answer is "3x + 7 / x + 2."
Hope this helps.
Answer:
( 3x+7 ) / ( x+2 )
Step-by-step explanation:
\frac{(x+4)(3x+7)}{(x+4)(x+2)}
When you set up the equation like a fraction, you can now cancel out like terms. (x+4) is in the denominator- as well as the numerator. They are the same in parentheses. So you can cancel. Once that's done, you'll be left with
\frac{3x+7}{x+2}
You cant simplify any further because there are no more (like groups) aka (common factors)
( 3x+7 ) / ( x+2 )

A sports analyst determines that the number of points
scored in a basketball game is related to the number of
shots taken during the game. The least-squares

The half-life of gold-195m is approximately 30.5 seconds.
Step 2 of 3: How much of a 12 gram sample of gold-195m would remain after 41 seconds? Round to three decimal places.
The amount of the 12 grams sample of gold-195m having a half-life of 30.5 s that would remain after 41 s is 4.726 g
How to determine the number of half-lives Half-life (t½) = 30.5 sTime (t) = 41 sNumber of half-lives (n) =?n = t / t½
n = 41 / 30.5

Answer:
7. odd angles, 143°; even angles, 37°
8. odd angles, 159°; even angles, 21°
9. even angles, 34°; odd angles, 146°
10. even angles, 29°, odd angles, 151°
Step-by-step explanation:
Angles 1 and 3 are vertical angles, so are congruent. The same can be said of angles 2 and 4. Each odd-numbered angle is supplementary to each even-numbered angle.
__
7. m∠1 = m∠3 = 143°, m∠2 = m∠4 = 180° -143° = 37°
8. m∠1 = m∠3 = 159°, m∠2 = m∠4 = 180° -159° = 21°
9. m∠2 = m∠4 = 34°, m∠1 = m∠3 = 180° -34° = 146°
10. m∠2 = m∠4 = 29°, m∠1 = m∠3 = 180° -29° = 151°

Angle θ forms a reference angle that is below the positive x axis (in quadrant IV). What will be the signs on the sine and cosine of angle θ?
Answer:
sin(θ) is negative, cos(θ) is positive
Step-by-step explanation:
Cosine corresponds to the x-coordinate within the unit circle, sine corresponds to the y-coordinate. In quadrant I, they are both positive, in quadrant II, x is negative whilst y is positive, and you would just continue by how they correspond as show in the unit circle, therefore, in quadrant IV, x is positive, y is negative.
what are the x- and y- intercepts for the graph of 3x + y = 15?
Answer:
X intercept=(5,0) and Y intercept=(0,15)
Step-by-step explanation:
3x + y = 15
to find the x int, sub in 0 for y and solve for x
3x + 0 = 15
3x = 15
x = 15/3
x = 5....so the x int is (5,0)
to find the y int, sub in 0 for x and solve for y
3(0) + y = 15
y = 15....so the y int is (0,15)
What is the area of the region in the first quadrant bounded on the left by the graph of x=y^2/2 and on the right by the graph of x=3y−4 for 2≤y≤4 ?
The area of the region is -2/3 square units
The area bounded by the regionSince the region is bounded on the left by x = y²/2 and on the right by x = 3y - 4 for 2 ≤ y ≤ 4, the area of the region is given by
[tex]A = \int\limits^4_2 {\frac{y^{2}}{2} } \, dy - \int\limits^4_2 {(3y - 4)} \, dy \\[/tex]
Integrating, we have
A = [y³/6]₂⁴ - [3y²/2 - 4y]₂⁴
A = [4³/6 - 2³/6] - [3(4)²/2 - 4(4) - {3(2)²/2 - 4(2)]}]
A = [64/6 - 8/6] - [3(16)/2 - 16 - {3(4)/2 - 8]}]
A = [64/6 - 8/6] - [3(16)/2 - 16 - {3(4)/2 - 8]}]
A = [64/6 - 8/6] - [3(8) - 16 - {3(2) - 8]}]
A = [(64 - 8)/6] - [3(8) - 16 - {3(2) - 8]}]
A = [56/6] - [24 - 16 - {6 - 8}]
A = [56/6] - [8 - {-2}]
A = [56/6] - [8 + 2]
A = [56/6] - [10]
A = 56/6 - 10
Taking the L.C.M, we have
A = (56 - 10 × 6)/6
A = (56 - 60)/6
A = -4/6
A = -2/3 square units
So, the area of the region is -2/3 square units
