Answer:
Brian spent 62.5294 $.
Step-by-step explanation:
The cost of two shirts = [tex]2\times \:14.5=29[/tex] $
The cost of 1 pair of shoes = [tex]1\times 29.99\:[/tex] = [tex]29.99[/tex] $
Adding the calculated costs = [tex]29+29.99=58.99[/tex] $Tax calculation:
[tex]\frac{6}{100}\times \:58.99=3.5394[/tex] $Now, adding calculated costs and tax calculation:
58.99$ + 3.5394$ = 62.5294 $
Therefore, Brian spent 62.5294 $.
10,24,26 determine whether the triangle is obtuse, right, acute, or not a triangle
Answer:
right triangle
Step-by-step explanation:
10 + 24 = 34
34 > 26
Therefore, there is a triangle.
Now we use the Pythagorean theorem.
10^2 + 24^2 = 100 + 576 = 676
26^2 = 676
Since 10^2 + 24^2 = 26^2, the triangle is a right triangle.

Answer no 8 ,9 and 10
Answer:
8) 4 + 2q²/p² - 4r/p + r²/p²9) (3/4, -9/4)10) (3/8, 41/16)Step-by-step explanation:
8. ============
Given
α and β are roots of px² + qx + r = 0The sum of the roots is α + β = -q/p, the product of then roots αβ = r/p
(2 + α²)(2 + β²) = 4 + 2(α² + β²) + (αβ)² =4 + 2((α + β)² -2αβ) + (αβ)² =4 + 2((-q/p)² - 2r/p) + (r/p)² =4 + 2q²/p² - 4r/p + r²/p²------------------------------
9. ============
Given function
y = 2x² - 3x - 1The minimum point is reached at vertex
The vertex is:
x = -b/2ax = -(-3)/2*2 = 3/4The corresponding y-coordinate is:
y = 2(3/4)² - 3(3/4) - 1 = 9/8 - 9/4 - 1 = 1/8(9 - 18 - 9) = - 18/8 = - 9/4So the point is:
(3/4, -9/4)---------------
10. ============
Given function
y = 2 - 3x - 4x²The maximum is reached at vertex
The vertex is:
x = -b/2ax = -(-3)/2(-4) = -3/8The corresponding y-coordinate is:
y = 2 - 3(-3/8) -4(-3/8)² = 2 + 9/8 - 9/16 = 1/16(32 + 18 - 9) = 41/16So the maximum point is:
(3/8, 41/16)what's the answer to this question= 4(3x + 2) + 2(x + 3)
A. 12x + 16
B. 24x + 48

Answer:
1. D
2. F
3. F
4. C
5. F
6. B
Step-by-step explanation:
1. To find the slope, take two points from the table (in this case I'll use points (-3, 7) and (-1, 4)) and put them into the expression: [tex]\frac{y2-y1}{x2-x1}[/tex]
[tex]\frac{4-7}{-1-(-3)}[/tex]
Solve:
4 - 7 = -3
-1 - (-3) = -1 + 3 = 2
The slope is -[tex]\frac{3}{2}[/tex]
2. I used the same process I used in number 1 using the points (-2, 4) and
(1, -1)
3. The slope of both equations represents how much each t-shirt was sold for. This means that whichever equation has a higher slope made greater profits. The slope of store B is 3.75 - we know this because the equation given is in y = mx, where m is the slope. To find the slope of store A, use the method I used in question 1 using two points from the graph ( I used points (0, 0) and (10, 40)). The slope of store A is 4, which is greater than 3.75, meaning that Store A made a greater profit per t-shirt.
4. To find the slope and y-intercept of this equation, let's convert the equation to slope-intercept form, y= mx + b, where m is the slope and b is the y-intercept. To do this we have to isolate the y:
y + 9x = -6
Subtract 9x from both sides to isolate the y:
y + 9x - 9x = -6 - 9x
y = -6 - 9x
This equation can also be written as: y = -9x - 6
Now we can see that the slope is -9 and the y-intercept is -6.
5. Slope-intercept form is y = mx + b, where m is the slope and b is the y-intercept. Slope is also known as rise over run. Looking the graph, for every 2 points it decreases on the y-axis, it increases by 1 on the x-axis. This can be written as -2/1, or simply -2. To find the y-intercept, find the point on the graph where the line intersects the y-axis. In this case, it's at y = -1. Now that we know the values of our slope and y-intercept, we can put them into the equation:
y = mx + b
y = -2x - 1
6. The y-intercept represents the amount Alice will have to pay for the game center before she pays for any guests. This value is $100.

Can someone please answer this for me please??
I honestly do not understand, can someone please help me understand?
Answer:
15/16
Step-by-step explanation:
Using the order of operations, we need to multiply in the parentheses first...
3/5*25/24=75/120, which simplifies to 5/8.
Next, we need to divide 5/8 by 2/3. To divide, we can actually multiply by the reciprocal, which is flipping the fraction that you are dividing by. In this case, we need to multiply 5/8 by the reciprocal of 2/3. The reciprocal of 2/3 is 3/2, so we need to multiply 5/8 by 3/2.
5/8*3/2=15/16
This is the final answer!

How many solutions does the following equation have?
9x - 4 = - 3x + 5 + 12x
O One Solution
O No Solution
O Infinitely Many Solutions
Answer:
There will be No solution for the equation [tex]9x - 4 = - 3x + 5 + 12x[/tex]. Option B is correct.
Step-by-step explanation:
We need to determine how many solutions the equation [tex]9x - 4 = - 3x + 5 + 12x[/tex] have.
Solving the equation and finding the solutions
[tex]9x - 4 = - 3x + 5 + 12x[/tex]
Combining like terms, Moving 3x and 12x to left side of equality and changing their signs and moving 4 on right side of equation and changing sign.
[tex]9x +3x-12x = 5 + 4[/tex]
Simplifying
[tex]12x-12x = 9\\0=9[/tex]
Solving the equation we get 0=9 which is false. So, there will be No solution for the equation [tex]9x - 4 = - 3x + 5 + 12x[/tex]. Option B is correct.

Describe a pattern in each sequence. Then find the next two terms of the difference.
1, 5, 25, 125, …
1, 5, 25, 125
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by
5 gives the next term. In other words, an=a1⋅rn−1. Geometric Sequence: r=5
This is the form of a geometric sequence.an=a1rn−1 Substitute in the values of a1=1 and r=5.an=(1)⋅(5)n−1 Multiply (5)n−1 by 1. an=5n−1
