Answer:
x = -3
Step-by-step explanation:
y = x + 8 and x + y = 2
Using substitution, we know that y = x + 8, so:
x + y = 2
x + (x + 8) = 2
2x + 8 = 2
2x = -6
x = -3
Then we solve for y:
x + y = 2
-3 + y = 2
y = 2 + 3
y = 5

Mr. phill stopped to fill his car with gas on the way to New York. It took 1 ¼ minutes to fill a 15 liters of gas in his tank. At this rate, how long will it take to fill his 50 liter gas tank?
Answer:
4 1/6 min or 4 min 10 secStep-by-step explanation:
Filling rate is:
15 ÷ 1 1/4 = 15 ÷ 5/4 = 15 × 4/5 = 12 l/minTotal volume is 50 l, time required to fill is:
50/12 = 4 2/12 = 4 1/6 min or 4 min 10 secPLEASE HELP- A triangle has vertices A(0, 0), B (9, 4), and C(–2, 10). What are the coordinates of the triangle after a dilation with a scale factor of 1/2 ?
Basically multiply the x and y coordinates of each point by 1/2
For example, I'll do C which is ( -2 , 10 )
-2 * 1/2 = -1 and 1/2 * 10 = 5
The new coordinate is ( -1 , 5 )
Now you can try the other points
:D

bus driver drove from Philadelphia to Washington D.C. He drove the first 100 km in 2 hours, the next 55 km in 1 hour, and the final 75 km in 2 hours. What is the average speed of the bus throughout the trip?
Answer: I think it’s 46
Step-by-step explanation: Because you add up the miles he drove them divide them by how long he drove
Ex 55+75+100=230 then you divide that by 5 hours = 46 per hour

Answer:
an = n + 1
Step-by-step explanation:
This arithmetic sequence has a first term of 2 and a common difference of ...
3 - 2 = 1
The general term is ...
an = a1 + d(n-1)
Using a1=2 and d=1, this is ...
an = 2 +1(n -1)
an = 2 + n - 1 . . . . . eliminate parentheses
an = n + 1 . . . . . . . .collect terms

Answer 1. And 2.for Brainliest
Answer:
Step-by-step explanation:
10% discount means you pay 90% of the original cost x.
90% of x = $40.50
0.90x = $40.50
x = $40.50/0.90 = $45
:::::
total cost = 1.065·$40.50 ≅ $43.13
Draw the graph of the equation x − y = 4
Answer the following using graph paper:
(i) Find the value of y, if x = 7 from the graph.
(ii) Write the coordinate of the point where the graph intersect on x − axis.
Answer:
We have the equation:
x - y = 4
We can write this as a linear equation in the slope-intercept form if we isolate the variable y.
We get:
y = x - 4
Now to graph this function, we need to evaluate x in two different points and get two points (x, y) of the line.
If we use x = 1 and x = 2, then we get:
y(1) = 1 - 4 = - 3
Then we have the point (1, -3)
and:
y(2) = 2 - 4 = - 2
Then we have the point (2, - 4)
Now we need to draw these two points in the coordinate axis, and draw a line that connects the points, the example can be seen in the image below.
a) To use the graph, we need to locate the value x= 7 in the x-axis.
Then draw a vertical line
In the point where the vertical line intersects the graph, we draw an horizontal line.
The y-value will be the value at which this horizontal line intersects the y-axis
In this case, is at y = 3.
Then when x = 7, y = 3.
(you can see it in the graph)
ii) The coordinate at which the graph intersects the x-axis can be seen in the graph, it is the point (0, 4)

In a video game, a guppy that escapes a net turns into three goldfish. Each goldfish can turn into two betta fish. Each betta fish can turn into two angelfish. Complete the diagram and write the number of fish at each stage. Write and evaluate an expression for the number of angelfish that can be formed from one guppy
Answer: 1 guppy = 3 goldfish
1 goldfish = 2 betta fish.....so 3 goldfish = (3 * 2) = 6 betta fish
1 betta fish = 2 angel fish....so 6 beta fish = (6 * 2) = 12 angel fish
so the number of angelfish that can be formed by 1 guppy is 12 angelfish

Formula of area
AREA = LENGTH (multiply) BREATH
Answer:
The area of a triangle can be calculated with the formula: 1/2(bh), where b is the base length, and h is the height.
In this case, 4 is the base, and 7 is the height.
So we have: Area = 1/2(4)(7)
Simplifying: Area = 2(7), Area = 14.
The area of the triangle is 14 meters squared.

A thunderstorm travels at a constant speed. In 15 minutes , the storm travels 12 miles. If the storm continues to travel at the same rate, how far would it travel in 90 minutes?
Answer: 72 Miles In 90 Minutes
Step-by-step explanation: First, you have to divide both 15 & 12 by 15, (which represents minutes), and you get 1 over 0.8. Next, you multiply 1 over 0.8 times 90, which gibes you 90/72. There is your answer! I hope that you found this helpful.
Here is the equation below:
15/12 divided by 15/15 = 1/0.8 x 90/90 = 90 MINUTES/72MILES

Harry buys a TV priced at £1200 plus 20% VAT.
He pays £300 deposit and the balance in ten equal monthly payments .
Calculate each monthly payment.
Answer:
114
Step-by-step explanation:
20% of 1200= 240
so total price is 1200+220=1440
he pays 300 beposit
1440-300=1140
now 1150 must be paid in 10 installments equally
11400÷10=114 is the answer

Brainliest gets 45 points so please help ASAP
Answer:
y = -3/8(x - 4)² + 7 or y = -3/8x² + 6x + 1Step-by-step explanation:
We can see on the graph that the vertex is (4, 7) and the leading coefficient is negative as parabola opens down.
The vertex form is:
y = a(x - h)² + k, substitute coordinates to get,y = a(x - 4)² + 7Considering the y-intercept is (0, 1), substitute values to find the value of a:
1 = a(0 - 4)² + 7a(4²) = 1 - 716a = -6a = -6/16a = -8/3The function is:
y = -3/8(x - 4)² + 7In standard form:
y = -3/8(x² - 16x + 16) + 7 = -3/8x² + 6x - 6 + 7 = -3/8x² + 6x + 1
