Step-by-step explanation:
1.
The given equation is :
6x+2y=14
We need to write it in the function form.
Taking 2 common from both sides,
2(3x+y)=2(7)
So,
(3x+y)=7
Subtract 3x from both sides,
y+3x-3x=7-3x
y = 7-3x
So, the correct option is (c).
2. f(x) = 3x-4
We need to find f(2). Put x = 2 in the above function.
f(2) = 3(2)-4
= 6-4
= 2
The correct option is (D).

The width of a rectangle measures (4d – 8) centimeters, and its length measures
(7d – 3) centimeters. Which expression represents the perimeter, in centimeters, of
the rectangle?
Answers
Answer:
(22d-22) cm
Step-by-step explanation:
perimeter= 2×(4d-8+7d-3)
= 2× (11d-11)
(22d - 22) cm
Answer:
(22d-22)cm
Step-by-step explanation:
Perimeter = 2 x (width + Length)
= 2 x [(4d – 8) + (7d – 3)]
= 2 x (11d-11)
= (22d-22)cm

Answers
Answer:
98 degrees
Step-by-step explanation:
first find angle G
53 + 45 + G = 180
subtract 45 and 53 from both sides
G = 82
angle g is supplementary (add up to 180) to x
x +82 = 180
subtract 82 from both sides
x = 98
Answer:
x = 98°
Step-by-step explanation:
There are 180° in a triangle, and 180° on a line.
180° - 53° - 45° = 82°
180° - 82° = 98°

Answers
Answer:
Weak positive
Step-by-step explanation:
From. Visual inspection of the scatter plot, the line of best fit will have a positive slope has values of x tends to increase with a corresponding increase in the value of y.
However, the points are scattered across the plotting area meaning that most of the points will be a bit farther away from the regression line. This means a weak correlation between the x and y variables will be obtained. Since the slope is positive, theb the relationship between the variables based on the scatterplot interpretation is a weak positive correlation.

[tex]-\frac{\sqrt{21}}{2}[/tex]
Step-by-step explanation:
ASTC (I use a sentence to memorize: All Students Take Calculus):
Q1 - All functions are positive
Q2 - Sine is positive (Cosecant is positive as well) (all others negative)
Q3 - Tangent is positive (Cotangent is positive as well) (all others negative)
Q4 - Cosine is positive (Secant is positive as well) (all others negative)
Applying ASTC:
Secant is negative, so it can't be in quadrant 1, and quadrant 4.
Quadrant 2 - Sine and Quadrant 3 - Tangent are left.
Cosecant is positive so it can't be in quadrant 3.
Therefore, angle x is in Quadrant 2 or QII
Secant is hypotenuse / adjacent
5 = hypotenuse (hypotenuse is never a negative number)
-2 = adjacent
use pythagorean theorem to solve for opposite (bc tan = opp / adj)

The circumference of a circle is about 33.912 inches. The circle's radius is __ inches.
Use 3.14 for π.
Answers
Answer:
5.4
Step-by-step explanation:
Circumference = 2 x 3.14 x radius
To find this information, you must first divide:
33.912 ÷ 2 = 16.956
Then, divide:
16.956 ÷ 3.14 = 5.4
So then your answer is:
Radius = 5.4

Which statement best describes the association between variable X and variable Y?
Answers
Answer:
weak, negative association
Step-by-step explanation:
If variables have a strong association, the points will form a clear line/curve. Since the graph's points are scattered and fairly chaotic, we can say the association is weak.
Positive associations trend upwards and negative associations tend downwards. This graph seems to overall tend downwards, so we can say the association is negative.
