Answer:
Ax + Ay + 2A = 0 for any nonzero A, for example (A=1): x + y + 2 = 0
Step-by-step explanation:
The equation of a line is
Ax + By + C = 0
so we know that:
A*-3 + B*1 + C = 0
A*5 + B*-7 + C = 0
Let's subtract one from the other:
A*(-3 - 5) + B*(1 + -7) = 0
A*-8 + B*8 = 0
B*8 = A*8
B = A
Let's input B = A into the first two equations
A*-3 + A*1 + C = A*-2 + C = 0
A*5 + A*-7 + C = A*-2 + C = 0
checks out
C = 2A
So for any nonzero A the equation of
Ax + Ay + 2A = 0 produces a line passing between the points. Example would be
x + y + 2 = 0
What is the area of this shape?
Answer: 98 in2
• First let split the shape into 2 rectangles.
We’ll be using the formula: b•h (base times height)
• Small rectangle:
7x3 = 21
• Bigger rectangle:
7x11 = 77
• Now we add both, which is:
21 + 77 = 98

A ramp has a height of five feet and a horizontal distance of 200 ft. What is the angle of elevation?
A 16
(6) 5.5°
(C 25.1°
D
1.4°
€ 2.3°
Answer:
1.4°
Step-by-step explanation:
Given that :
Height of ramp, h = 5 feets
Horizontal distance = 200 feets
The angle of elevation :
Using trigonometry :
Tanθ = opposite / Adjacent
Tan θ = 5 / 200
Tan θ = 0.025
θ = tan^-1 (0.025) = 1.43
θ = 1.4°

Complete the double number line
The given double number lines represent a linear function between cups of flour (c) and number of batched (n)
Pick any two pairs:
[tex](c_1,n_1) = (\frac{3}{4},1)[/tex]
[tex](c_2,n_2) = (3\frac{3}{4},5)[/tex]
First, calculate the rate of change (i.e. slope, m):
[tex]m = \frac{n_2 - n_1}{c_2 - c_1}[/tex]
[tex]m = \frac{5-1}{3\frac{3}{4} - \frac{3}{4}}[/tex]
[tex]m = \frac{4}{3}[/tex]
So: the equation is:
[tex]n = m(c - c_1) + n_1[/tex]
This gives:
[tex]n = \frac{4}{3}(c - \frac{3}{4}) + 1[/tex]
[tex]n = \frac{4}{3}c - 1 + 1[/tex]
[tex]n = \frac{4}{3}c[/tex]
So, the above represents the relationship between n and c.
To complete the table
When [tex]n = 2[/tex]
Substitute [tex]n = 2[/tex] in: [tex]n = \frac{4}{3}c[/tex]
[tex]2 = \frac{4}{3}c[/tex]
Make c the subject
[tex]c = \frac{3*2}{4}[/tex]
[tex]c = \frac{3}{2}[/tex]
When [tex]n = 3[/tex]
Substitute [tex]n = 3[/tex] in: [tex]n = \frac{4}{3}c[/tex]
[tex]3 = \frac{4}{3} * c[/tex]
Make c the subject
[tex]c = \frac{3*3}{4}[/tex]
[tex]c = \frac{9}{4}[/tex]
When [tex]c=3[/tex]
Substitute [tex]c=3[/tex] in: [tex]n = \frac{4}{3}c[/tex]
[tex]n = \frac{4}{3} * 3[/tex]
[tex]n = 4[/tex]
So, the complete table is:
[tex]c:0\ \ \ \frac{3}{4}\ \ \ \frac{3}{2}\ \ \ \frac{9}{4}\ \ \ 3\ \ \ 3\frac{3}{4}\\n:0\ \ \ \ 1\ \ \ 2\ \ \ 3\ \ \ \ 4\ \ \ \ 5[/tex]
Farmer Rew started with 92 quects on his farm. Every month, he
bought 5 more of them. Farmer Joogh started with 27 quects on her
farm. Every month, she purchased 9 more of them.
farmer's quects (y) as months (x) increase.
Answer:
y = 5x + 92
y = 9x + 27
Step-by-step explanation:
Slope intercept form is written as y = mx + b, and you know that y represents "quects" and x represents months.
For farmer Rew, b would be 92 because that is how many "quects" he started off with. m would be 5 because that is how many new "quects" he gets every month. (y = 5x + 92)
For farmer Joogh, b would be 27 because she started off with 27 "quects." m would be 9 because she gets 9 new "quects" every month. (y = 9x + 27)

Find the value x such that the data set has the given mean.
101,119,104,111,109,x mean 113
X=?
Answer:
x = 134
Step-by-step explanation:
The mean of a data set is calculated as
mean = [tex]\frac{sum}{count}[/tex]
Here mean = 113, then
[tex]\frac{101+119+104+111+109+x}{6}[/tex] = 113
[tex]\frac{544+x}{6}[/tex] = 113 ( multiply both sides by 6 )
544 + x = 678 ( subtract 544 from both sides )
x = 134

The difference of a number and 4 is no more than 8
Can someone help!?
Considering the definition of an inequality, the number must be less than 12.
Definition of inequalityAn inequality is the existing inequality between two algebraic expressions, connected through the signs:
greater than >.less than <.less than or equal to ≤.greater than or equal to ≥.An inequality contains one or more unknown values called unknowns, in addition to certain known data.
Solving an inequality consists of finding all the values of the unknown for which the inequality relation holds.
Inequality in this caseIn this case, you know that the difference of a number and 4 is no more than 8.
Being "x" the number you want to know, and considering that the difference is the difference between two numbers or expressions, the inequality that expresses the previous relationship is
x - 4 < 8
Solving:
x < 8 +4
x < 12
Finally, the number must be less than 12.
