If C=r+7 and D=-2r+3, find an expression that equals 2C−D in standard form.
Answer:
[tex]\huge\boxed{\boxed{\bf\:4r + 11}}[/tex]
Step-by-step explanation:
Given,
C = r + 7D = - 2r + 3We need to find the value of 2C - D. To solve this, we need to substitute the values of C & D in the expression. So,
[tex]\tt\:2\:C - D\\\\\sf\:{Substitute \: the \: given \: values}\\\\\tt\:= 2(r + 7) - (-2r + 3)\\\\\sf\:Now, \: follow \: the \: distributive \:property\\\\\tt\:= 2r + 14 + 2r - 3\\\\\sf\:Rearrange\:the\:terms\\\\\tt\:= 2r + 2r + 14 - 3\\\\\sf\:Do \: the \: required \:arithmetic \: operations\\\\=\boxed{ \bf\:4r + 11}[/tex]
[tex]\rule{200}{2}[/tex]
The answer will be 4r + 11 in the standard form.[tex]\rule{200}{2}[/tex]
Hope this helps!
The expression that equals 2C - D is 4r+ 11
How to determine the expressionThe expressions are given as:
C=r+7 and D=-2r+3
The expression 2C - D is calculated as follows:
2C - D = 2 * (r + 7) - (-2r + 3)
Expand
2C - D = 2r + 14 +2r - 3
Collect like terms
2C - D = 2r +2r+ 14 - 3
Evaluate the like terms
2C - D = 4r+ 11
Hence, the expression that equals 2C - D is 4r+ 11

OC) 126
OD 127
Answer:
OA) 14
Step-by-step explanation:
2((7+1)-1)
2(8-1)
You could expand the brackets then simplify or just simplify now. It will be better to simplify now though but I will do both methods.
Simplifying first:
2(7) = 2 × 7 = 14
Our answer is 14 So answer is OA) 14
Expanding first then simplifying:
2(8-1) = 16-2 = 14
Our answer is 14 So answer is OA) 14
Answer:
14
Step-by-step explanation:
Substitute the values into the equation.
2((a +b) - b)
2((7 + 1) -1)
You can use Distribute first or Solve the parenthesis first it will still give the same answer.
Distributive method.
2((7 + 2) -2)
=((14 + 2) -2)
= 16 -2
=14
Or solve the parenthesis first.
2((7 + 1) -1)

First we do the prime factorisation of 300:
2²×3×5²
Now we put this into our surd:
[tex]\sqrt{(2^{2})(3)(5^{2}) }[/tex]
Now we split them up:
[tex]\sqrt{2^{2} } \sqrt{3} \sqrt{5^{2} }[/tex]

Katie owns a pretzel stand. Her profit, in dollars, is given by the function , where is the number of pretzels sold. What is the maximum profit , in dollars, Katie can earn?
Using the vertex of the quadratic equation, it is found that the maximum profit she can earn is of $106.
What is the vertex of a quadratic equation?A quadratic equation is modeled by:
[tex]y = ax^2 + bx + c[/tex]
The vertex is given by:
[tex](x_v, y_v)[/tex]
In which:
[tex]x_v = -\frac{b}{2a}[/tex]
[tex]y_v = -\frac{b^2 - 4ac}{4a}[/tex]
Considering the coefficient a, we have that:
If a < 0, the vertex is a maximum point.If a > 0, the vertex is a minimum point.In this problem, her profit is modeled by:
[tex]P(x) = -x^2 + 14x + 57[/tex]
Which is a quadratic equation with coefficients a = -1, b = 14, c = 57, hence, her maximum profit in dollars is given by:

Keecia joins a gym. She pays a membership fee of $75.00 and $49.99 per month for the first 8 months. The gym increases its rates, and she must pay $59.99 per month for the next 4 months. Which numerical expression can be used to find the total cost of the first year of Keecia’s gym membership?
Answer:
$165 is the total cost of the first year of Keecia’s gym membership
Step-by-step explanation:
formula for direct proportion : y = kx
x = 50
y = 75
50 = k * 75
k = 75/50
k = 3/2x
substitute y = 60
60 = 3/2x
x = 3/2 * 60
x = 90
$90 + $75 = $165

what is the value of the expression (y+6)*7
Answer:
7y+42
Step-by-step explanation:
If I am doing this correctly (so take it with a grain of salt from just waking up) you would multilpy 7 with the expressions in the ( )
So it would be 7*y= 7y
Then 7*6= 42
So it would be 7y+42 I think
Sorry if it is incorrect/ doesn't answer your question. Good luck!
Answer:
[tex]\displaystyle \large{7y+42}[/tex]
Step-by-step explanation:
We are given the expression [tex]\displaystyle \large{(y+6) \cdot 7}[/tex]. Use the distributive property to simplify the expression.
Distributive Property
[tex]\displaystyle \large{a(b+c)=ab+ac}[/tex]
To say it simply, you multiply the outside with the insides. Therefore, from the expression:-

Select the correct answer. A parabola has an x-intercept of -1, a y Intercept of -3, and a minimum of 4 at x = 1. Which graph matches this description?
Answer:
D
Step-by-step explanation:
If the parabola has an x-intercept of -1, we are looking for the curve to intercept the x-axis at x = -1
Graphs A and D both have x-intercepts at x = -1
If the parabola has a y-intercept of -3, we are looking for the curve to intercept the y-axis at y = -3
The only graph with a y-intercept at y = -3 is Graph D
FYI the minimum of Graph D is at (1, -4)

A circular mirror is surrounded by a square metal frame. The radius of the mirror is 2x. The side length of the metal frame is 8x. What is the area of the metal frame?
Answer:
183.43x2
Step-by-step explanation:
Area of the entire frame = (14x)2 = 196x2
Area of the mirror = pi(2x)2 = 4x2(pi)
Area of the frame surrounding the mirror = (196 - 4pi)x2 = 183.43x2

Answer:
7m = t, 42, 56
Step-by-step explanation:
If each mile takes 7 minutes, then the chart is correct in saying that 4 miles takes 28 minutes (7 • 4 = 28)Using this information, we can set up the equation with the knowledge that 7m = t (or, one mile takes 7 minutes)The blanks would be 42 and 56 because we multiply M by 7 each time to get T. For example, we would multiply 6 by 7 to get 42 minutes.If I am incorrect in my reasoning, please let me know so that I can plan better for my future answers. Have an amazing day.
