Only answer if you know how to do the equation
Let's find the slope of the line passing through it :
[tex] \boxed{ slope = \frac{y_2-y_1}{ x_2- x_1} }[/tex]
[tex] \dfrac{ -5 - ( - 6)}{0 - ( - 5)} [/tex][tex] \dfrac{1}{5} [/tex]Now, we know, equation of a line is :
[tex]\longrightarrow y = mx + b[/tex]
where,
m represents the slopeTherefore,
[tex]\longrightarrow \: y = \dfrac{1}{5} x + b[/tex]
let's put the value of x and y from the first coordinates .
[tex]y = \dfrac{x}{5} + b[/tex][tex] - 5 = \dfrac{0}{5} + b[/tex][tex]b = - 5[/tex]Hence, we got the equation of line as :
[tex]y = \dfrac{x}{5} - 5[/tex]or

Bill had 5 tests over the marking period. He knows he is receiving a 85 on his report card. He was looking back at his test and only has four grades: 80, 90, 100, 85. What was the score of the missing test? Please no silly answers or links ill report you.
Answer:
70
Step-by-step explanation:
(Not the most streamlined way but.)
Knowing that if he had 5 tests, and a mark of 85, we can determine the total average grade Bill received. 85*5=425
Then subtract the known grades
425-(90+85+100+80)=x
425-(355)=x
70=x
Bill would have scored 70 on that 5th test
Find the length of the following sides:
DF
AB
EF
Answer:
DF) = 10
AB) = 5
EF) = 12.5
Step-by-step explanation:
For length AB
[tex]3^{2} +4^{2} = AB^{2}[/tex] -> 9+16=[tex]\sqrt{25}[/tex] -> 5
For length DF
We know that AD is 2.5 times smaller than DE (7.5 / 3)
Now we can use that to determine length DF
BD = 4, DF = 4*2.5 = 10
using the Pythagorean theorem, you can find EF:
[tex]DE^{2} +DF^{2} =EF^{2}[/tex]
[tex]7.5^{2}+ 10^{2} =12.5[/tex]

Find the value of x
Answer:
The value of x is 18
Step-by-step explanation:
24 x 15 is 360. ( x + 12 ) x 12 = 360 as well. So, 360÷12=30. 30-12 = 18. So the full equation is (18+12)x12=24×15 which are both equal to 360.
Find the selling price
Cost of the computer; $1,850.00
Markup: 75%
Answer:
2466.67
Step-by-step explanation:
1850/.75=2466.67
The cost of selling price of the computer is, $3,237.5
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
Given that;
Cost of the computer = $1,850.00
Markup = 75%
Now,
The cost of selling price of the computer is,
⇒ $1,850 + 75% of $1,850
⇒ $1850 + 75 /100 × $1850
⇒ $1850 + $1387.5
⇒ $3,237.5

$20.565hope it helps
stay safe healthy and happy.Answer:
Part A: $12.325
Part B: $20.565
Step-by-step explanation:
PART A:
To find the answer, we multiply 2.9 and 4.25 together: 2.9 * 4.25 = 12.325
The cost of 2.9 pounds of dark chocolate is $12.325
PART B:
To find the answer, we multiply 1.6 and 5.15 together: 1.6 * 5.15 = 8.24
After that, to find the cost of the dark and milk chocolate together, we add up the two answers: 12.325 + 8.24 = 20.565
The total cost of the milk and dark chocolate is $20.565
Note: You might need to round it up. In this case, Part A is $12.33 and Part B is $20.57

Finding Percents Using Decimals 1.8 of 240
Answer:
I think 4.32...............
1.) Determine the type of solutions for the function (Picture 1)
2.) Determine the type of solutions for the function (Picture 2)
3.) Use the formula b2−4ac to determine the value of the discriminant of the function f(x)=2x2+8x+6
Use Desmos Scientific (Picture 3)
4.) Describe the transformations of the function
g(x)=−25(x−4)2+6 from the transformation of the parent function
Use phrases such as: the graph is reflected or not reflected/ the graph gets wider or narrower/ the graph slides left or right _________ units and slides up or down _________ (Picture 4)
Answer:
1) 2 nonreal complex roots
2) 1 Real Solution
3) 16
4) Reflected, narrower by a factor of 2/5, slides right 4 units and slides up 6 (units)
Step-by-step explanation:
1) The graph does not intercept the x-axis, therefore, there are no real solutions at the point y = 0
We get;
y = a·x² + b·x + c
At y = 6, x = -2
Therefore;
6 = a·(-2)² - 2·b + c = 4·a - 2·b + c
6 = 4·a - 2·b + c...(1)
At y = 8, x = 0
8 = a·(0)² + b·0 + c
∴ c = 8...(2)
Similarly, we have;
At y = 8, x = -4
8 = a·(-4)² - 4·b + c = 16·a - 4·b + 8
16·a - 4·b = 0
∴ b = 16·a/4 = 4·a
b = 4·a...(3)
From equation (1), (2) and (3), we have;
6 = 4·a - 2·b + c
∴ 6 = b - 2·b + 8 = -b + 8
6 - 8 = -b
∴ -b = -2
b = 2
b = 4·a
∴ a = b/4 = 2/4 = 1/2
The equation is therefor;
y = (1/2)·x² + 2·x + 8
Solving we get;
x = (-2 ± √(2² - 4 × (1/2) × 8))/(2 × (1/2))
x =( -2 ± √(-12))/1 = -2 ± √(-12)
Therefore, we have;
2 nonreal complex roots
2) Give that the graph of the function touches the x-axis once, we have;
1 Real Solution
3) The given function is f(x) = 2·x² + 8·x + 6
The general form of the quadratic function is f(x) = a·x² + b·x + c
Comparing, we have;
a = 2, b = 8, c = 6
The discriminant of the function, D = b² - 4·a·c, therefore, for the function, we have;
D = 8² - 4 × 2 × 6 = 16
The discriminant of the function, D = 16
4.) The given function is g(x) = (-2/5)·(x - 4)² + 6
The parent function of a quadratic equation is y = x²
A vertical translation is given by the following equation;
y = f(x) + b
A horizontal to the right by 'a' translation is given by an equation of the form; y = f(x - a)
A vertical reflection is given by an equation of the form; y = -f(x) = -x²
A narrowing is given by an equation of the form; y = b·f(x), where b < 1
Therefore, the transformations of g(x) from the parent function are;
g(x) is a reflection of the parent function, with the graph of g(x) being narrower by 2/5 than the graph of the parent function. The graph of g(x) is shifted right by 4 units and is then slides up by 6 units.

6 + y= -8 ????????????????
Answer:
y = -14
Step-by-step explanation:
6 + y = -8
Subtract 6 from both sides to get y by itself.
y = -14.
Proof:
6 + y = -8
Substitute the variable.
6 + (-14) = -8
Add the negative/Subtract.
-8 = -8.
Answer:
y=−14
Step-by-step explanation:
Let's solve your equation step-by-step.
6+y=−8
Step 1: Simplify both sides of the equation.
y+6=−8
Step 2: Subtract 6 from both sides.
y+6−6=−8−6
y=−14
brainliest please?David wanted to go on an amusement park ride. A sign posted at the entrance read “You must be greater than 42 inches tall and no more than 57 inches tall for this ride.” Which inequality would model the height, x, required for this amusement park ride?
Answer:
42 < x less than or equal to 57
Step-by-step explanation:
The inequality that would model the height, x, required for this amusement park ride is 57 > h > 42.
What is inequality?A statement of an order relationship-greater than, greater than or equal to, less than, less than or equal to- between two numbers or algebraic equations
Now it is given that,
Lower limit of height must be greater than 42 inches
Upper limit of height must be less than 57 inches
If h is the height used for model.
Thus, h < 57 inches
and, h > 42 inches
Therefore the inequality model will be,
57 > h > 42
Thus, the inequality that would model the height, x, required for this amusement park ride is 57 > h > 42.

Find the x intercepts of the graph of -6x + 5y =24. State your answers as while numbers or as improper fractions in simplest form.
Answer:
x-intercept: -4
y-intercept: 24/5
Step-by-step explanation:
Firstly you have to isolate the y:
-6x + 5y = 24
5y = 6x + 24
y = (6x +24)/5
Now, just think about the graph: when the function touch the x-axis, the value of y is equal to 0, and when the function touch the y-axis, the value of x is 0, so just put they in the function:
y = (6•0 + 24)/5
y = 24/5
0 = (6x + 24)/5
5•0 = 6x +24
0 = 6x +24
-6x = 24
x = 24/-6
x = -4
