Answer:
y = 4
Step-by-step explanation:
If 3 is x than you can substitute x for 3. y = 3 + 1. Then when you add y = 4
y = x+1
y = 3+1
y= 4
that's how you solve it... Good luck
[-3 1/4] greater or less than [-4]
Answer:
[-3 1/4] is greater than [-4]
Step-by-step explanation:
When doing negative numbers greater or less than problems, you always want to look for the smallest negative. This is because the smaller a negative is, the greater it is that a bigger negative number

69. The O'Brien's had $400.0 in a special
checking account for installment payments
After paying $40.00 a month for three months
and $20.00 a month for two months. How
much was left in the account?
Hello :D
$40.00 x 3 = $120.00
$20.00 x 2 = $40.00
$120.00 + $40.00 = $160.00
$400.00 - $160.00 = $240.00
There is $240.00 left in the account.
If f(x) = 3x - 4 and g(x)=x?, find the value of
f(3) - g(2)
A) 4
B) 9
C) 1
D) 7
Answer:
C) 1
Step-by-step explanation:
f(x) = 3x - 4 when x = 3
= 3(3) - 4
= 9 - 4
= 5
g(x) = x^2 when x = 2
= 4
Subtract both values.
5 - 4 = 1
Best of Luck!
Does the following represent a function?
f = [ (3, -1), (2, 5), (4, -6), (3, 4), (5, -8) ]
Answer:
Not a function
Since x= produces y- -1 and y=-4, the relation (3,-1),(2,5),(4,-6),(3,4),(5,-8) is not a function.

9514 1404 393
Answer:
D. 72sin(α)cos(α)
Step-by-step explanation:
Given two sides and the angle between, the area of a triangle can be found from the formula ...
Area = (1/2)ab·sin(C)
Here, that translates to ...
Area = (1/2)(12)(y)sin(α)
Using the trig relation ...
Cos = Adjacent/Hypotenuse
we can find y:
cos(α) = y/12
y = 12·cos(α)
__
Substituting this into the area calculation above, we have ...
Area = (1/2)(12)(12·cos(α))sin(α)
Area = 72sin(α)cos(α)

A calculator can help with these, especially if it is able to deal with rational numbers. (Many graphing calculators and some scientific calculators will do that more or less nicely. My favorite Android calculator app makes arithmetic with fractions and mixed numbers very easy.)

Solve the following inequality. Use interval notation.
9514 1404 393
Answer:
(-∞, -1/3) U (3, ∞)
Step-by-step explanation:
The given inequality is equivalent to two inequalities (joined with OR).
-(3x -4) +3 ≥ 8
-3x +7 ≥ 8 . . . . . . eliminate parentheses
-3x ≥ 1 . . . . . . . subtract 7
x ≤ -1/3 . . . . . divide by 3
3x -4 +3 ≥ 8
3x ≥ 9 . . . . . add 1
x ≥ 3 . . . . . . divide by 3
Then the solution to the inequality is the union of these intervals:
x ∈ (-∞, -1/3) ∪ (3, ∞)

BC=
On a number line, suppose point E has a coordinate of −3,and EG=8.What are the possible coordinates of point G?
The possible coordinates for G are?
Please help!
Answer:
30
Step-by-step explanation:
AC = AB + BC
48 = 2x + 2 + 3x + 6
48 = 5x + 8
48 - 8 = 5x
40 = 5x
40/5 = x
8 = x
Finding BC
BC = 3x + 6
BC = 3(8) + 6
BC = 24 + 6
BC = 30
#2
Coordinate = -3 + 8 = 5
Answer:
BC = 305Step-by-step explanation:
We know that adding AB and BC will give us AC so we can create an equation and solve for x.
2x + 2 + 3x + 6 = 48
~Combine like terms
5x + 8 = 48
~Subtract 8 to both sides
5x = 40
~Divide 5 to both sides
x = 8
Now that we know the value of x, we can solve for BC.
= 3(8) + 6
= 24 + 6
= 30
I would assume 8 is the length of EG so we would add that value to -3 and find where that would be at on the number.
-3 + 8 = 5

The graph shows the result of a matrix transformation, where the pre-image has dashed lines. Which matrix operation is represented in the graph?
The matrix operation needed to transform the original matrix (pre-image) is represented by option C. ( [tex]T' = \left[\begin{array}{cc}-1&0\\0&-1\end{array}\right]\cdot \left[\begin{array}{cccc}-5&-8&-5&-3\\-9&-7&-3&-6\end{array}\right][/tex]. )
The operation used to obtain the image in dash lines is a rotation around the origin, which is defined by following vectorial expression:
[tex]T' = R\cdot T[/tex] (1)
Where:
[tex]T[/tex] - Original matrix (pre-image).[tex]R[/tex] - Rotation matrix.[tex]T'[/tex] - Resulting matrix (image).Where the original matrix is defined by the following matrix:
[tex]T = \left[\begin{array}{cccc}x_{1}&x_{2}&...&x_{n}\\y_{1}&y_{2}&...&y_{n}\end{array}\right][/tex] (2)
And the rotation matrix is:
[tex]R = \left[\begin{array}{cc}\cos \theta&-\sin \theta\\\sin \theta&\cos \theta\end{array}\right][/tex] (3)
Where [tex]\theta[/tex] is the rotation angle, in sexagesimal degrees.
If we know that [tex]\theta = 180^{\circ}[/tex], [tex](x_{1}, y_{1}) = (-5, -9)[/tex], [tex](x_{2},y_{2}) = (-8,-7)[/tex], [tex](x_{3},y_{3}) = (-5, -3)[/tex] and [tex](x_{4}, y_{4}) = (-3, -6)[/tex], then the resulting matrix is represented by this entity:
[tex]T' = \left[\begin{array}{cc}-1&0\\0&-1\end{array}\right]\cdot \left[\begin{array}{cccc}-5&-8&-5&-3\\-9&-7&-3&-6\end{array}\right][/tex]
The matrix operation [tex]T' = \left[\begin{array}{cc}-1&0\\0&-1\end{array}\right]\cdot \left[\begin{array}{cccc}-5&-8&-5&-3\\-9&-7&-3&-6\end{array}\right][/tex] is represented in the graph.

Find the area of this figure. round your answer to the nearest hundredth.
Answer:
The area of the figure is 49.12ft² (nearest hundredth)
Step-by-step explanation:
The area of the figure is the sum of the areas of the right triangle and semi circle that make up the figure.
Note that the radius of a circle is twice its diameter
That means, the radius of the semi-circle is 4 feet
Area of the triangle = 1/2 x Base X Height = 1/2 x 6 ft x 8 ft =24 ft²
Area of the semi circle = 1/2 πr² = 1/2 x 3.14 x 4² = 25.12 ft²
Hence, the area of the figure is:
24 ft² + 25.12 ft² = 49.12 ft²

P, Q, V, and K are collinear with V between K and P, and Q between V and K. If VP = 14x + 4, PK = x + 630, VQ = 17x + 6, and KQ = 11x + 5, solve for VP.
9514 1404 393
Answer:
VP = 214
Step-by-step explanation:
The order of points on the line is KQVP. The whole is the sum of the parts, so we have ...
KQ +QV +VP = KP
(11x +5) +(17x +6) +(14x +4) = x +630
42x +15 = x +630 . . . . . . . . . . . . . . . . . collect terms
41x = 615 . . . . . . . . . . . subtract x+15
x = 15 . . . . . . . . . . divide by 41
Then the measure of VP is ...
VP = 14x +4 = 14·15 +4 = 210 +4
VP = 214
Hello so can someone help me with this problem. My teacher doesn't explain it very well </3
[tex] t= 50 + \frac{n - 4}{4} [/tex]
switch sides
[tex]50 + \frac{n - 4}{4} = t[/tex]
subtract 50 from both sides
[tex]50 + \frac{n - 4}{4} - 50 = t - 50[/tex]
simplify
[tex] \frac{n - 4}{4} = t - 50[/tex]
simplify
[tex] \frac{n - 4}{4} = t - 50[/tex]
multiply both sides by 4
[tex]4 \frac{(n - 4)}{4} = 4t - 4 \times 50[/tex]
simplify
[tex]n - 4 = 4t - 200[/tex]
add 4 both sides
[tex]n - 4 + 4 = 4t - 200 + 4[/tex]
[tex] n = 4t - 196[/tex]
