Answer:
x = {-4, -2}Step-by-step explanation:
To find the intersection we need to solve the system:
y = 2x + 3(x - 3)² + (y + 6)² = 50Solve by substitution, replace y with 2x + 3 in the second equation:
(x - 3)² + (2x + 3 + 6)² = 50x² - 6x + 9 + 4x² + 36x + 81 - 50 = 05x² + 30x + 40 = 0x² + 6x + 8 = 0x² + 6x + 9 = 1(x + 3)² = 1x + 3 = ± 1x = -4, x = -21. Classify the triangle according to side length and angle measurement.

What is the surface area of the box if it is scaled up by a factor of 10? here are the measurements: length: 11in width: 5in height: 5in
surface area is 270in
Answer:
27000in
Step-by-step explanation:
you have to multiply everything by 10 and then find the surface area again.
(length: 11in width: 5in height: 5in) * 10
(length: 110in
width: 50in
height: 50in
Finding the new surface area:
SA = 2(lw + lh + wh)
SA = 2((110)(50) + (110)(50) +(50)(50))
SA = 2(5500 + 5500 + 2500)
SA = 2(13500) = 27000

A string reaches from the top of a 17-foot pole to a point 13 feet from the base of the pole. To the nearest tenth of a foot, how long is the string?
Answer:
21.4 feets
Step-by-step explanation:
Using Pythagoras rule :
The length of the string:
Hypotenus = sqrt(opposite² + adjacent²)
Length of string = sqrt(17² + 13²)
Length = sqrt(289 + 169)
Length of string = sqrt(458)
Length of string = 21.400
Length = 21.4 feets

The average test score for 8 students is 5 the scores for 7 of the 8 students are shown what is the score of the 8th student
Answer:
70
Step-by-step explanation
Find the diagram attached
Average = Sum of scores/sample size
Given the 7 numbers
20, 20, 20, 30, 80, 80, 80
Average = 50
5 = 20+20+20+30+80+80+80+x/8
x is the score of the 8th student
50 = 330+x/8
400 = 330+x
x = 400-330
x = 70
Hence the score of the 8th student is 70

The area of triangle given in the given image is 180 [tex]m^2[/tex] as per the given data.
What is area of an triangle?To calculate the area of a triangle, you must first determine the length of the base and the height of the triangle.
The base can be any of the triangle's sides, and the height is the perpendicular distance between the base and the opposite vertex.
The formula for calculating the area of a triangle is A = (1/2) x b x h, where A is the area of the triangle, b is the length of the triangle's base, and h is the height of the triangle.
We know that,
Area = 1/2 x b x h
Here, it is given that:
Base = 30m
Height = 12m
So,
Area = 1/2 x 30 x 12
Area = 180[tex]m^2[/tex]
Thus, the answer is 180[tex]m^2[/tex].

Patrice found a book that was 2 1/4 inches thick. She stacked it with another book that was the same thickness. How tall was the stack ?
Answer:
4.5. inches
Step-by-step explanation:
Given that:
Thickness of first book = 2 1/4 inches
Thickness of second book = same as first = 2 1/4 Inches
Stacking both books together, height of stack will be :
2 1/4 inches * 2
Height of stack = 9/4 * 2
Height of stack = 18 /4 = 4.5 inches

The diameter of a circle is 38 miles. What is the circle’s area?
Use 3.14 for pi
Area of circle formula: πr^2
Since the radius is half of the diameter, divide 38 by two.
r = 19 miles
A = π(19)^2 = π(361)
Now, substitute in 3.14 for π
A = 3.14(361) = 1133.54

Match each function on the left to all points on the right that would be located on the graph of the function
By direct evaluation we have found the following results about functions and points:
The points (1, - 3) and (5, 5) are part of the function f(x) = 2 · x - 5.The point (1, 1) is part of the function f(x) = 2 · x² - 8 · x + 7.The point (4, 1) is part of the function f(x) = 2√(x - 4) + 1.What function does a point belong to?Herein we have three functions and four points which has to be checked with respect to each of these functions. A quick approach consists in evaluating each function at every value of x and choose from the outputs.
Case A
f(1) = 2 · 1 - 5
f(1) = - 3
f(4) = 2 · 4 - 5
f(4) = 3
f(5) = 2 · 5 - 5
f(5) = 5
The points (1, - 3) and (5, 5) are part of the function f(x) = 2 · x - 5.
Case B
f(1) = 2 · 1² - 8 · 1 + 7
f(1) = 1
f(4) = 2 · 4² - 8 · 4 + 7
f(4) = 7
f(5) = 2 · 5² - 8 · 5 + 7
f(5) = 17
The point (1, 1) is part of the function f(x) = 2 · x² - 8 · x + 7.
Case C
f(1) = 2√(1 - 4) + 1
f(1) = NaN
f(4) = 2√(4 - 4) + 1
f(4) = 1
f(5) = 2√(5 - 4) + 1
f(5) = 3
The point (4, 1) is part of the function f(x) = 2√(x - 4) + 1.

Answer:
B
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = - 1 and c = - 6 , then
y = - x - 6 → B
