write an equation of the line passing through the point A(-1, 5) that is perpendicular to the line y=1/7x+4
y = 1/7x + 4
1/7 * a2 = -1
a2 = -7
y = -7x + b
A = (-1, 5)
-7 * (-1) + b = 5
7 + b = 5
b = -2
y = -7x - 2

Answer:
3/4 = 16/x. Step-by-step explanation: Set up the original ratio: 3:4 (a.k.a. 3/4 or 3 to 4) Because 16 correlates to red paint and 3 correlates to red paint the will be in the same location (as the numerator or denominator).. Also, the amount of blue paint is unknown so that is x.4 also represents blue paint, so 4 and x will also be on the same level (as the numerator of denominator).

solve the system of equations x + y = 0 and x + 9y= -48 by combing the eqatuons
Answer:
x = 6
y = -6
Step-by-step explanation:
x + y = 0 (Multiply by -1)
x + 9y= -48
-x - y = 0
x + 9y= -48
8y = -48
y = -6
x + y = 0
x - 6 = 0
x = 6

Charles correctly answered 23 questions on a test receiving a grade of 92% how many questions where on the test
Answer:
25
Step-by-step explanation:
Cross multiply
23/x=92/100
x=25
There were approximately 25 questions on the test.
To determine the number of questions on the test, we can set up a proportion based on Charles' correct answers and the grade received.
Let x be the total number of questions on the test.
We can set up the proportion:
23 (Charles' correct answers) / x (total number of questions) = 92% (grade as a decimal: 0.92)
This can be written as:
23 / x = 0.92
To solve for x, we can multiply both sides of the equation by x:
23 = 0.92 * x
Dividing both sides by 0.92:
23 / 0.92 = x
x ≈ 25
Therefore, there were approximately 25 questions on the test.

HELP!!!!!Which property can you apply to Hayley's expression to show that it is equivalent to Gretchen's expression?
Complete question :
Gretchen and her friend Hayley bought three bags of apples and three bunches of bananas from the fruit vendor. Gretchen and Hayley want to find the total number of pieces of fruit that they bought. Gretchen thinks she should multiply 3 by the number of apples in each bag, x, and add it to 3 times the number of bananas in each bunch, y, to find the total number of pieces of fruit. Hayley thinks Gretchen should add the number of apples in each bag, x, to the number of bananas in each bunch, y, and then multiply that sum by 3.
Which property can you apply to Hayley’s expression to show that it is equivalent to Gretchen’s expression?
Answer:
The distributive property of multiplication
Step-by-step explanation:
Number of apples per bag = x
Number of bananas per bunch = y
3 each of bananas and apples were bought
Expression to obtain the total fruits bought :
Gretchen's expression :
3x + 3y
Haley's expression :
3(x + y)
According to the distributive property :
Haley's equation :
3(x + y)
(3 * x) + (3 * y)
3x + 3y
Hence, Gretchen's expression = Haley's expression by the distributive property of multiplication.

Write the equation in slope-intercept form.
y - 5 = 3(x-3)

Formula: Y=mx+b

Answer y= 3x+5
The coefficient of x is the slope of the parallel line, option (C) m=3 is the correct answer.
What is slope of a line?The slope or gradient of a line is a number that describes both the direction X and Y and the steepness of the line. It is the ratio of the vertical change to the horizontal change between any two distinct points on a line.
For the above situation,
The equation is y = 3x - 2.
The general form of equation for slope intercept form is [tex]y = mx + b[/tex]
Now compare the given equation with the general equation,
⇒ [tex]m=3[/tex].
Since the lines are parallel, the slope will be the same for all lines.
So, slope for the parallel line is also m = 3.
Now the equation in slope-intercept form that intersects the point (3,5) is
⇒ [tex]y - y1 = m(x-x1)[/tex]
⇒ [tex]y - 5 = 3(x-3)[/tex]
⇒ [tex]y-5=3x-9[/tex]
⇒ [tex]y=3x-9+5[/tex]
⇒ [tex]y=3x-4[/tex]
Hence we can conclude that the coefficient of x is the slope of the parallel line, option (C) m=3 is the correct answer.

A paper company produces 1,890 notebooks in 2 days. How many notebooks can it produce in 10 days?
Answer:
9450
Step-by-step explanation:
1890/2 gives you 945 which is one days worth. multiply by ten you get 9450
Answer:
Number of notebooks produced in 2 days = 1890
Number of notebooks produced in 1 day = ?
We have to divide the number of notebooks produced by the number of days it took:
[tex] \frac{1890}{2} \\ = 945[/tex]
So, 945 books are produced in a day by the company.
Number of notebooks produced in 10 days = ?
Now, we have to multiply the number of notebooks produced in 1 day & the number of days asked in the question:
[tex]945 \times 10 \\ = 9450[/tex]
=> 9450 notebooks are produced by the Paper Company in 10 days.
