Answer:
The slope is -3/4 or -0.75
Step-by-step explanation:
You can solve this using the slope of a line formula:
[tex]m=\frac{rise}{run}=\frac{y_{2}-y_1 }{x_2-x_1}[/tex]
m = slope
[tex](x_1,y_1)[/tex] = coordinates of first point in the line
[tex](x_2,y_2)[/tex] = coordinates of second point in the line
Now all you have to do is plug your numbers in and solve!

Please give brainliest, i need 3 more :)
Answer:
24.3
Step-by-step explanation:
Here we need to evaluate,
[tex]\longrightarrow 3^3 +14.7\div 7-(1.2\times 4)[/tex]
First of all we need to know about BODMAS , which stands for ,
B = BracketsO = of D = divisionM = multiplicationA = AdditionS = SubtractionThis means first we need to solve brackets , then of , then division , then multiplication, then addition and finally subtraction.
In the given questions, firstly solve the terms inside the brackets ,
[tex]\longrightarrow 3^3 +14.7 \div 7 -(1.2\times 4)[/tex]
Multiply 1.2 and 4 ,
[tex]\longrightarrow 3^3+14.7\div 7-(4.8) [/tex]
Now perform division , that is divide 14.7 by 7
[tex]\longrightarrow 3^3 + 2.1 - 4.8 [/tex]
Simplify 3³ .
[tex]\longrightarrow (3)(3)(3)+2.1-4.8= 27+2.1-4.8[/tex]
Add ,
[tex]\longrightarrow 29.1 -4.8[/tex]
Finally subtract,
[tex]\longrightarrow \underline{\underline{\boldsymbol{ 24.3 }}}[/tex]

5x - 6 = 3x + 4
X= -2
X= 5
All real numbers
X=2
Answer:
x = 5
Step-by-step explanation:
Step 1: Write equation
5x - 6 = 3x + 4
Step 2: Solve for x
Subtract 3x on both sides: 2x - 6 = 4Add 6 to both sides: 2x = 10Divide both sides by 2: x = 5Step 3: Check
Plug in x to verify it's a solution.
5(5) - 6 = 3(5) + 4

I’m in 7th grade and I need help :(((( I don’t understand adding, subtracting, multiplying, dividing numbers. Like this is all I know Ik this is for multiply and divide but Ik a negative times negative = positive and positive time’s positive = positive and negative times positive = negative and positive time’s negative = negative but can someone tell me the thing like that but for adding and subtracting please
Hi! Hope this helps
(- stands for negative and + stands for positive)
Adding
- plus + = - or + depending on the numbers (If you have -7 + 3 it equals -4, but -3 + 7 = 4)
+ plus + = + (Simple)
- plus - = - (Like regular addition, except -2 + -3 would be -5)
Subtraction
- minus + = - (If you have -7 - 3 it equals -10, and -3 - 7 = -10)
- minus - = + (If you have -3 - (-4) = 1)
+ minus + = - or + depending on the numbers ( If you have 8 - 4 it equals 4, but if you subtract 8 from 4, it is -4

Will get 100 points and a brainlist. Calculate the height of this rectangle. Please help ASAP!
Answer:
height = 1/2 ft
Step-by-step explanation:
area of rectangle = width × height
Given:
area = 5/6 ft²width = 5/3 ft⇒ 5/6 = 5/3 × height
⇒ height = 5/6 ÷ 5/3
⇒ height = 5/6 × 3/5
⇒ height = 15/30
⇒ height = 1/2 ft
During the summer, Alex earns some money mowing his neighbors' lawns. He is being paid $6.00 per hour. In June, he worked 11 hours. In July, he worked 19 hours. How much money did he earn in June and July altogether?
Answer:
$180
Step-by-step explanation:
Alex gets paid for $6.00 PER hour
In June:
Alex worked for 11 hours.
In July:
19 hours.
You can do 19*6.00 (Lets just do 19*6 for now to make it easier)
19*6=114
Change it to $144.00
In June:
You can do 11*$6.00. '(Lets just do 11*6 for now to make it easier)
11*6=66.
Change it to $66.00
Add the money Alex earned.
June + July= $66+144=$180
Mrs. Adesso wants to take her class on a trip to either the science center or natural history museum. The science center charges $7 per student, plus $75 for a guided tour. The natural history museum charges $8 per student, plus $50 for a guided tour. For what number of students is the cost of the trip the same at each museum?
Answer:
25
Step-by-step explanation:
When we write expressions for the total cost of each field visit and set them equal, we find the solution to be the ratio of the difference in fixed cost to the difference in variable cost.
y = 75 +7x . . . . . cost for x students to visit the science center
y = 50 +8x . . . . cost for x students to visit the natural history museum
__
Subtracting the first equation from the second, we get ...
0 = -25 +x
25 = x . . . . . add 25; the number of students such that costs are equal
The cost will be the same either place for 25 students.
__
Additional comment
Here, the fixed cost difference is 75-50=25, and the variable cost difference is 8-7=1. The ratio of these costs is ...
$25/($1 /student) = 25 students.
This relationship only holds when the higher fixed cost is associated with the lower variable cost. Charges are such that one place caters to larger numbers of students (science center), and one prefers fewer students (natural history museum).

Factor completely. 36c^2−8cd+49d^2
[tex]\huge\bold\green{Answer:-}[/tex]
Simplifying
36c2 + -84cd + 49d2 = 0
Reorder the terms:
-84cd + 36c2 + 49d2 = 0
Solving
-84cd + 36c2 + 49d2 = 0
Solving for variable 'c'.
Factor a trinomial.
(6c + -7d)(6c + -7d) = 0
Subproblem 1
Set the factor '(6c + -7d)' equal to zero and attempt to solve:
Simplifying
6c + -7d = 0
Solving
6c + -7d = 0
Move all terms containing c to the left, all other terms to the right.
Add '7d' to each side of the equation.
6c + -7d + 7d = 0 + 7d
Combine like terms: -7d + 7d = 0
6c + 0 = 0 + 7d
6c = 0 + 7d
Remove the zero:
6c = 7d
Divide each side by '6'.
c = 1.166666667d
Simplifying
c = 1.166666667d
Subproblem 2
Set the factor '(6c + -7d)' equal to zero and attempt to solve:
Simplifying
6c + -7d = 0
Solving
6c + -7d = 0
Move all terms containing c to the left, all other terms to the right.

6c = 0 + 7d
Remove the zero:
6c = 7d
Divide each side by '6'.
c = 1.166666667d
Simplifying
c = 1.166666667d
Solution
c = {1.166666667d, 1.166666667d}
