Answer: Yes, there is an ordered pair solution
The quick way we can see this without having to graph or do any algebra is to look at the two slopes of the lines.
y = x+1 has slope of 1
y = -x+5 has slope of -1
Recall that y = mx+b has slope m.
The two different slopes (1 and -1) indicate the lines are not parallel, so they must intersect exactly once. This intersection is the where the solution is located.

Answer:
The answer is b (1,11)
Step-by-step explanation:
You can graph the lines and find the solution that way (which is where the lines intersect)
or you can algebraically solve.
To check this, you can basically plug in the x and y values for the equation and see if they match with what the equation equals..
Example:
10x + 3y = 43
-9x - y = -20
10(1) + 3(11) --> 10 + 33 = 43.. 43 equals 43
-9(1) - (11) = -9 - 111 = -20.. -20 equals -20
(the values match up so it's a solution)

Answers
Answer:
Equation can be used to find the number of candles (c) Katie ordered is 54 = 3c + 6 .
Option (C) is correct .
Step-by-step explanation:
A. 3c = 54
B. 6c = 54
C. 3c + 6 = 54
D. 3c – 6 = 54
As given
Katie ordered candles that cost $3 each from a website.
She was charged a flat shipping fee of $6 and no sales tax.
If she spent a total of $54,
c represented the number of candles .
Equation becomes
Total cost = Cost per candle + Flat shipping fee
54 = 3 × c + 6
54 = 3c + 6
Equation can be used to find the number of candles (c) Katie ordered is 54 = 3c + 6 .
Option (C) is correct .

The Royal Fruit Company produces two types of fruit drinks. The first type is 70%

pure fruit juice. The company is attempting to produce a fruit drink that contains 75%
pure fruit juice. How many pints of each of the two existing types of drink must be used to make 90
pints of a mixture that is 75%
pure fruit juice?
Step-by-step explanation:
To make the desired drink we need to add 30 pints of 95% of the drink, and 80 pints of 40% of the drink.
What is volume?Volume, which is measured in cubic units, is the 3-dimensional space occupied by matter or encircled by a surface. The cubic meter (m3), a derived unit, is the SI unit of volume. Volume is another word for capacity.
Given, The Royal Fruit Company produces two types of fruit drinks. The first type is 40% pure fruit juice, and the second type is 90% pure fruit juice.
Let,
a = Volume of 40% of drink
b = volume of 95% of drink
Since the two existing types of drink must be used to make 110 pints of a mixture that is 55% pure fruit juice
a + b = 110
0.4a + 0.95 b = 110 * 0.55
Comparing these equations we will get,
a = 80
and b = 30
Therefore, To make the desired drink we need to add 30 pints of 95% of the drink, and 80 pints of 40% of the drink.

A graph shows time (minutes), numbered 2 to 18 on the horizontal axis (t), and altitude in feet, numbered 30 to 270 on the vertical axis (h). A solid circle appears at point (0, 210) and point (14, 0), and a line connects the 2 points.
What is the domain of the function represented in the graph?
{t| 0 ≤ t ≤ 14}
{h| 0 ≤ h ≤ 210}
{t | 0 ≤ t ≤ 210}
{h | 0 ≤ h ≤ 14}
Answers
Answer:
its A
Step-by-step explanation:
Carl wheezer told me
The domain of the function will be {t| 0 ≤ t ≤ 14}. so the correct option is A.
Since we know that the domain of a function refers to the set of possible input values or the values that the independent variable can take.
Thus, the independent variable is represented by the horizontal axis, which is time (t) in minutes.
We are given that the solid circle appears at point (0, 210) and point (14, 0), and a line connects these two points.
The x-coordinate of the first point is 0, and the x-coordinate of the second point is 14. So, the time values that correspond to these points are 0 minutes and 14 minutes, respectively.
We can see that the function is defined from time 0 to time 14.
Therefore, the correct answer is:
{t | 0 ≤ t ≤ 14}
This means that the domain of the function is the set of all possible values of t such that t is greater than or equal to 0 and less than or equal to 14.

Step-by-step explanation:
The value of f(-4) in the polynomial functions f(x) = 2x² - x + 9 is 45
How to evaluate the function?The function is given as:
f(x) = 2x² - x + 9
Substitute -4 for x
f(-4) = 2(-4)² - (-4) + 9
Evaluate the exponents
f(-4) = 2(16) - (-4) + 9
Evaluate the product
f(-4) = 32 - (-4) + 9

Find the units of displacement (translation) of the point (4,2) to get the image of (7,7). Chapter (transformation) (coordinates) (translation). Step by step answer please.
Answers
Answer:
The rule of the translation will be:
(x, y) → (x+3, y+5)
Step-by-step explanation:
Translation of an object is basically termed as "sliding" the original. If the image is moved right by the 'c' units, the 'c' unit(s) are added to the x-coordinate and if the image is moved left by the 'c' units, the 'c' unit(s) are subtracted to the x-coordinate.
And If the image is moved up by the 'c' units, the 'c' unit(s) are added to the y-coordinate and if the image is moved down by the 'c' units, the 'c' unit(s) are subtracted to the x-coordinate.
As the point is (4, 2)
The image of the point is (7, 7)
As the coordinates of the image point indicate that 3 units are added to the x-coordinate of the original point, and 5 units are added to the ý-coordinate.
Hence, the image will be move 3 units to the right and 5 units up.
Therefore, the rule of the translation will be:
(x, y) → (x+3, y+5)
as
(4, 2) → (x+3, y+5) = (4+3, 2+5) = (7, 7)
