(8,-7)m=-3/4 write an equation in point slope form of the line that passes through the given point and has the given slope
Answer:
Equation of the straight line in point-slope form
y -(-7) = [tex]\frac{-3}{4}[/tex](x-8)
Equation of the straight line
3x +4y +4=0
Step-by-step explanation:
Explanation:-
Given that the point ( 8,-7) and [tex]m = \frac{-3}{4}[/tex]
Equation of the straight line passing through the point (x₁, y₁) and having slope 'm'
y - y₁ = m (x-x₁)
y -(-7) = [tex]\frac{-3}{4}[/tex](x-8)
4( y+7) = -3(x-8)
4y +28 = -3x +24
3x +4y +28 -24 =0
3x +4y +4=0
The area in square feet of a rectangular garden can be expressed as the product of the garden’s length and width, or A(x) = 3x2 +13x +14. If the width of the garden is (x + 2) feet, what is the length of the garden?
Answer:
3x+7
Step-by-step explanation:
Use long division or synthetic division. (3x^2+13x+14)/(x+2)
The length of the rectangular garden is 3x + 7
The given expression:
[tex]A = 3x^2 + 13x + 14[/tex]
the width of the garden = x + 2
let the length of the garden = y
To find:
the length of the gardenThe area of the rectangular garden is calculated as;
[tex]A = y(x + 2) = 3x^2 + 13x + 14\\\\y(x + 2) = 3x^2 + 13x + 14\\\\y = \frac{3x^2 + 13x + 14}{x + 2}[/tex]
Using long division method:
3x + 7
------------------------------
x + 2 √ 3x² + 13x + 14
- (3x² + 6x)
-------------------------
7x + 14
- (7x + 14)
-------------------------------
0
Thus, the length of the rectangular garden, y = 3x + 7

In a class in which the final course grade depends entirely on the average of four equally weighted 100-point tests, Joyce has scored 90, 93, and 85 on the first three. What range of scores on the fourth test will give Joyce a C for the semester (an average between 70 and 79, inclusive)? Assume that all test scores have a non-negative value.
Express your answer in interval notation.
HELP ASAP BRAINLEST AND THANKS
Answer:
[12,48]
Step-by-step explanation:
We will start by calculating the score she needs to get a 70 in the class
We will let x equal the fourth test
[tex]\frac{90+93+85+x}{4} =70[/tex]
This isn't hard to solve and we will do so by multiplying 4 by both sides and subtracting 268 (90+93+85)
This means that x= 12
We will then use the same formula but set it equal to 79
[tex]\frac{90+93+85+x}{4} =79[/tex]
We solve x in the exact same way and get x=48
our final answer is now [12,48]

Lines n and m (reading from top to bottom) are parallel to each other, and lines a and e are parallel to each other. The two pairs of lines intersect each other. Lines m and n start at top left and drop to the bottom right. Lines a and e rise from left to right. Only six of the sixteen angles created are labelled. Angle one is the top angle made by lines n and a. Angle two is the bottom angle. Angle three is the bottom angle made by lines m and a. Angle four is the top angle made by lines n and e. Angle five is the left angle. Angle six is the bottom angle made by lines m and e.

A construction manager needs 12 workers to complete a building project in 54 days. Find in terms of T the number of workers needed to complete the same project in T days
Answer:
2T/9Step-by-step explanation:
A construction manager needs 12 workers to complete a building project in 54 days, we can write;
12 workers = 54 days
T find the number of workers needed to complete the same project in T days, we will write;
x workers = T days
Divide both equations
12/x = 54/T
Cross multiply
12T = 54x
x = 12T/54
x = 2T/9
Hence the number of workers needed to complete the same project in T days is 2T/9 workers

Determine the intercepts of the line

x-intercept (__,__)
What is the value of x?
Answer:
x = 30 degrees
Step-by-step explanation:
Okay so we start by noticing that the two pointed out vertices = 180 degrees. So we have the following equation.
(x + 12) + (3x + 48) = 180
If you combine them you get:
4x + 60 = 180
Subtract 60 from both sides..
4x = 120
Divide both sides by 4..
x = 30
And there's your answer!
