The sum of a number and six is seven times the number.
Which is a translation of the sentence into an equation?
n + 6 = 7n
n − 6 = 7n
7(n + 6) = n
n = 7n + 6
Answer:
n + 6 = 7n
Step-by-step explanation:
"The sum of a number and six" would mean the number plus 6: n+6 and "is seven times the number" indicates that it would be equal to the product of 7 for n: 7n. According to this, the answer is that the translation of the sentence into an equation is: n+6=7n.
n − 6 = 7n is not right because the statement says the sum of a number and six.
7(n + 6) = n is not right because the statement indicates that seven multiplies n on the right side as it says seven times the number.
n = 7n + 6 is not right because the statement says the sum of a number and six which would be on the left side and that this would be equal to seven for n.

A rectangular hotel room is 4 yards by 5 yards. The owner of the hotel wants to recarpet the room with carpet that costs $51.92 per square yard. How much will it cost to recarpet the room?
Answer:
it will cost him $2204 to recarpet the room.
Step-by-step explanation:
The floor of the room is rectangular. The formula for determining the area of a rectangle is expressed as
Area = length × width
The rectangular hotel room is 4 yards by 7 yards. It means that the area of the rectangular floor would be
Area = 4 × 7 = 28 square yard.
If the cost of the carpet $58.00 per square yard, the total that it will cost to recarpet the room would be
38 × 58.00 = $2204

Write the slope-intercept form of the equation of the line through the given point with the given slope. through: (-5, -1); slope = negative 3 over 5
Answer:
The slope-intercept form of the equation of the line is [tex]y = -\frac{3}{5} \cdot x -4[/tex].
Step-by-step explanation:
We know that the slope-intercept form of the equation of the line is represented by:
[tex]y = m\cdot x + b[/tex]
Where:
[tex]x[/tex] - Independent variable, dimensionless.
[tex]y[/tex] - Dependent variable, dimensionless.
[tex]m[/tex] - Slope, dimensionless.
[tex]b[/tex] - y-Intercept, dimensionless.
From statement we find that [tex]m =-\frac{3}{5}[/tex]. If [tex]x = -5[/tex] and [tex]y = -1[/tex], the value of the y-intercept is:
[tex]-1 =-\frac{3}{5}\cdot (-5)+b[/tex]
[tex]-1 = 3 + b[/tex]
[tex]b = -4[/tex]
The slope-intercept form of the equation of the line is [tex]y = -\frac{3}{5} \cdot x -4[/tex].

What are the vertex and x-intercepts of the graph of the function given below?
y = x2 - 2x-35
A. Vertex: (1, -36); intercepts: x = 7,-5
B. Vertex: (0,0); intercepts: x= -4,-5
C. Vertex: (7,5); intercepts: x = 7,8
D. Vertex: (1, -25); intercepts: x = 6,-4
Answer:the answer is A
Step-by-step explanation:
The vertex and x-intercepts of the graph of the function y = x²- 2x-35 is (1, -36) and intercepts: x = 7,-5, option A is correct.
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
The x-coordinate of the vertex can be found using the formula x = -b/2a, where a and b are the coefficients of the x² and x terms, respectively. In this case, a = 1 and b = -2, so x = -(-2)/(2×1) = 1.
Lets find the y-coordinate of the vertex.
To find the y-coordinate of the vertex, we substitute the x-coordinate we found in step 1 into the equation and evaluate.
y = (1)² - 2(1) - 35 = -36
So the vertex is at (1, -36).
Now find the x-intercepts.
To find the x-intercepts, we set y = 0 and solve for x.
0 = x² - 2x - 35
This equation can be factored as (x - 7)(x + 5) = 0.
So the x-intercepts are at x = 7 and x = -5.
Therefore, the vertex and x-intercepts of the graph of the function y = x²- 2x-35 is (1, -36) and intercepts: x = 7,-5, option A is correct.

Help someone please !!!!!!!!!!!!!!!!!!!!!!! The temperature one winter morning is -12 degrees fahrenheit,by noon,the temperatures rises by 5 degrees,and by 4p.m,the temperatures is 0 degrees. By how many degrees does the temperatures rise between noon and 4p.m., in degrees fahrenheit??
Answer:
The temperature rises 7 degrees between noon and 4pm.
Step-by-step explanation:
First, you add 5 to the -12. This gets you to the answer of 7. Then, since the temp. rises to 0 degrees by 4, you know that the difference between noon and 4 pm is 7 degrees.
solve the system
4x + 2y = 10
x = y + 13
Answer:
[tex]x = 6[/tex]
[tex]y = -7[/tex]
Step-by-step explanation:
We have the system of equations:
[tex]4x+2y=10\\x=y+13[/tex]
Let's solve by substituting. We know that [tex]x=y+13[/tex], so we can substitute [tex]y+13[/tex] in as [tex]x[/tex] in the equation [tex]4x+2y=10[/tex].
[tex]4(y+13) + 2y = 10[/tex]
Simplify this down so that we have [tex]y[/tex] on one side of the equation:
[tex]4y + 52 + 2y = 10\\\\6y + 52 = 10\\\\6y = -42\\\\y = -7[/tex]
Now that we know the value of [tex]y[/tex], we can substitute it in to the equation [tex]x = y+13[/tex] to find [tex]x[/tex].
[tex]x = -7+13\\\\x = 6[/tex]
Hope this helped!
Answer: (6,-7)
Step-by-step explanation:
4x +2y = 10
x = y + 13 Substitute the value of x into the first equation to solve for y.
4(y + 13) +2y = 10 apply the distributive property on the left side
4y + 52 + 2y = 10 Combine like terms on the left side
6y + 52 = 10 Subtract 52 from both sides
-52 -52
6y = -42
y= -7
The value of y so input it into one of the equations to solve for x
4x + 2(-7) = 10
4x - 14 = 10
+14 +14
4x = 24

Which parallelogram has an area of 60 square units?
Answer:
The answer is B
Step-by-step explanation:
Multiply base•height
Finding the area of each parallelogram, applying the formula, it is found that the parallelogram D has an area of 60 square units.
---------------------------
Similarly to a rectangle, the area of a parallelogram is given by height multiplied by base, that is:
[tex]A = hb[/tex]
---------------------------
In item A, the height is of 15 units and the base is of 10 units, thus, the area, in square units, is of [tex]15 \times 10 = 150[/tex].In item B, the height is of 6 units and the base is of 10.2 units, thus, the area, in square units, is of [tex]6 \times 10.2 = 61.2[/tex].In item C, the height is of 15 units and the base is of 15 units, thus, the area, in square units, is of [tex]15 \times 15 = 225[/tex].In item D, the height is of 10 units and the base is of 6 units, thus, the area, in square units, is of [tex]10 \times 6 = 60[/tex], which means that this is the correct option.A similar problem is given at https://brainly.com/question/14099239
Find the median and mean of the data set below: 35 , 28 , 19 , 18
Answer:
Hi there!
Your answer is:
Median: 23.5
Mean: 25
Step-by-step explanation:
The mean is the average of all the numbers in your dataset. You determine this by adding all the numbers together and dividing by the # of numbers in your set!
35+28+19+18 = 100.
100/4 = 25
The median is the middle number of your data set! This is determined by counting off the numbers from each side of the equation after setting them in order from least to greatest. If there are 2 remaining, you must find the average of those!

Does the point (2, 0) satisfy the equation y = x?
Answer:
no
Step-by-step explanation:
y = x
Substitute the point into the equation
0=2
This is not true so the point is not a solution
Hey there! I'm happy to help!
The point (2,0) does not satisfy the equation y=x. That means that x and y have to be equal. 2 and 0 are not equal. A point like (4,4) would satisfy that.
