For the equation, 2x+y=6, complete the following ordered pairs: (0,_), (_,0), (_,-6)
Answers in bold
(0, 6)
(3, 0)
(6, -6)
==============================================
Explanation:
The first point given is (0, _) where we don't know what goes in the blank just yet. Let's call this unknown y. The point is (0, y)
Plug in x = 0 to solve for y.
2x+y = 6
2*0+y = 6
0+y = 6
y = 6
Therefore, the point is (0,6) which is the y intercept. This is where the graph crosses the y axis.
------------------------
Next we move onto (_,0)
Plug in y = 0 to find x
2x+y = 6
2x+0 = 6
2x = 6
x = 6/2
x = 3
The point (_, 0) updates to (3,0) which is the x intercept. This is where the graph crosses the x axis.
------------------------
Lastly, we'll use y = -6 to find x.
2x+y = 6
2x-6 = 6
2x = 6+6
2x = 12
x = 12/2
x = 6
We go from (_, -6) to (6, -6)

A brand of frozen green beans lists a weight of 32 ounces on its bag. Because of variability in the manufacturing process, the bags often contain slightly more, or less, than 32 ounces of green beans. An inspector takes a random sample of 25 bags of green beans and records their weights. The weights and their relative frequencies are summarized in the histogram below.
A histogram titled Green Beans has actual weight (ounces) on the x-axis, and relative frequency on the y-axis. 31.8 to 31.9, 0.04; 31.9 to 32.0, 0.04; 32 to 32.1, 0.12; 32.1 to 32.2, 0.2; 32.2 to 32.3, 0.36; 32.3 to 32.4, 0.23.
Which interval contains the median bag weight?
31.9–32.0 ounces
32.0–32.1 ounces
32.1–32.2 ounces
32.2–32.3 ounces
The mode of the data lies at the end of the histogram, one can find that more values are concentrated at the ending of histogram, so the data is skewed data. Hence option 2: 32.0–32.1 ounces is the more appropriate.

Use f(x) = 5x − 4 and g(x) = 3 − x2 to evaluate the expression. (a) (f ∘ g)(−2) (b) (g ∘ f)(−2)
The composite functions are evaluated as:
a. (f ∘ g)(−2) = -9
b. (g ∘ f)(−2) = - 193
How to Solve Composite Functions?Given the functions,
f(x) = 5x − 4
g(x) = 3 − x²
a. To find the composite function, (f ∘ g)(−2), we will replace g(-2) instead of x in the function f(x).
Therefore, we would have:
(f ∘ g)(−2) = f(g(-2))
f(g(-2)) = 5(3 − (-2²)) − 4
f(g(-2)) = 5(3 − 4) − 4
f(g(-2)) = 5(-1) − 4
f(g(-2)) = -5 − 4
f(g(-2)) = -9
Therefore, (f ∘ g)(−2) = -9.
b. Also, the composite function (g ∘ f)(−2) would be evaluated by replacing f(-2) instead of x in g(x).
Therefore:
(g ∘ f)(−2) = g(f(-2))
g(f(-2)) = 3 − (5(-2) − 4)²
g(f(-2)) = 3 − (-10 − 4)²
g(f(-2)) = 3 − (-14)²
g(f(-2)) = 3 − 196
g(f(-2)) = -193
Therefore, (g ∘ f)(−2) = - 193

The approximate areas of Wisconsin and South Carolina are listed below:
Wisconsin: 1.7 x 105 square kilometers
South Carolina: 8.29 × 104 square kilometers
How much larger is Wisconsin? Express your answer using scientific notation.
Step-by-step explanation:
you mean
1.7 × 10⁵ square kilometers (km²) and
8.29 × 10⁴ km²
1.7 × 10⁵ = 17 × 10⁴
how much larger is this than
8.29 + 10⁴ ?
(17 - 8.29) × 10⁴ = 8.71 × 10⁴ km²
so, Wisconsin is 8.71 × 10⁴ km² larger than South Carolina.
This figure has two intersecting lines and a ray. What is the value of x? What is the measure of the angles? I NEED FULL DETAIL
The value of x in the intersecting lines is 7 and the measure of the angles are 38 and 52 degrees respectively.
How to solve angles?The sum of angles on a straight line is 180 degrees.
Complementary angles are angles that sum up to 90 degrees.
Therefore,
3x + 17 + 6x + 10 = 90 (complementary angle)
combine like terms
3x + 17 + 6x + 10 = 90
3x + 6x + 17 + 10 = 90
9x + 27 = 90
subtract 27 from both sides of the equation
9x + 27 = 90
9x + 27 - 27 = 90 - 27
9x = 63
divide both sides by 9
9x / 9 = 63 / 9
x = 7
3(7) + 17 = 21 + 17 = 38°
6(7) + 10 = 52°
Therefore, the two angles are 38 degrees and 52 degrees respectively.

Explanation:
We need to solve each expression individually:
1) 1/4 x + 5/2 x - 2 = 4 - 1/4 x
Collecting like terms:
1/4 x + 5/2 x + 1/4 x = 4 + 2
[tex]\begin{gathered} \frac{x\text{ + 5x(2) + x}}{4}=\text{ 6} \\ \frac{12x}{4}=\text{ 6} \\ 3x\text{ = 6} \\ x\text{ =2} \end{gathered}[/tex]2) 7.9x + x + 4 = -1.1x - 16
Collecting like terms:
7.9x + x + 1.1x = -16 -4
10x = -20
x = -20/10
x = -2
3) 3.2x + 5.7 = -2.5x
Collecting like terms:
3.2x + 2.5x = 5.7
5.7x = 5.7
x = 5.7/5.7
x = 1
4) 10.1x - 1.6x + 44 = -7

4. Jacob bought some tickets to see his favorite group, and it cost $76. The relationship between the adult tickets, a, and the student's tickets, s, can be expressed by the equation 10a + 8C = 76. If he bought 4 adult ticket, then how student's tickets did he buy? If he bought 2 student ticket, then how adult's tickets did he buy? Which equation shows the number of student tickets as a function of the number of adult tickets? A. C= 68 – 10a B.C=76 – 10a C. C= -4/5a +38/5 D. C=-5/4a+19/2
Given the equation:
[tex]10a+8c=76[/tex]If Jacob bought 4 adult tickets, then a = 4, so we can solve for c:
[tex]\begin{gathered} a=4 \\ \Rightarrow10(4)+8c=76 \\ \Rightarrow8c=76-40=36 \\ \Rightarrow c=\frac{36}{8}=\frac{9}{2}=4.5 \\ c=4.5 \end{gathered}[/tex]therefore, Jacob bought 4 or 5 students tickets.
Now, if Jacob bought 2 student tickets, then c=2 and for 'a' we have the following:
[tex]\begin{gathered} c=2 \\ \Rightarrow10a+8(2)=76 \\ \Rightarrow10a=76-16=60 \\ \Rightarrow a=\frac{60}{10}=6 \\ a=6 \end{gathered}[/tex]therefore, Jacob bought 6 adult tickets.
Finally, to find the equation that shows the number of student tickets as a function of adult tickets, we have to solve for 'c' to get the following:
[tex]\begin{gathered} 10a+8c=76 \\ \Rightarrow8c=76-10a \\ \Rightarrow c=-\frac{10}{8}a+\frac{76}{8}=-\frac{5}{4}a+\frac{19}{2} \\ c=-\frac{5}{4}a+\frac{19}{2} \end{gathered}[/tex]therefore, the function would be c = -5/4a +19/2

What temperature did Iron Man's suit start at?
We know that at the end of the battle, Iron Man's suit was at a temperature of -4.5 degrees Fahrenheit.
We know that Iceman decreased Iron Man's temperature by 73.2 F, so, if the initial temperature of the suit is T, then we can write the linear equation:
T - 73.2F = -4.5F
We can solve this equation for T.
T = -4.5F + 73.2F = 68.7F

The earliest known unit of length to be used in a major construction project is the “megalithic yard” used by. Builders of stone-henge in southwestern Britiian about 2600 b.c. If 1 megalithic yard= 2.72 plus minus 0.05 ft, convert this length to inches. (Round to the nearest tenth of an inch.)
1 megalthic yard = 2.722 feet ( this means they multiplied with 2.722 to get to feet)
now we need to convert feet to inches :
1 ft = 12 inches
2.722 ft = x
cross multiply
2.722 x 12 = 1 X
therefore x = 32,664
rounding off to the nearest tenth of an inch is equivalent to 32.6 inches

of the sale goes to the food cost?
The percentage of sale that goes to the food cost is 341.3%.
The ingredients for Apple crumble cost = $1.45 per serving.
The selling price of the Apple crumble = $4.95
percentage of the sale that goes to the food cost = ?
according to the question, we formulate:
% sale that goes to the food cost = cost of ingredients/selling price of the apple crumble×100
% sale = 4.95/1.45 × 100
% sale = 3.41 × 100
% sale = 341.3%
Hence the percentage of sale that goes to the food cost is 341.3%.
