Answer:
The answer is c, C=1.5w + 5
Step-by-step explanation:
Let's write a general equation first,
C = mw + b, where C represents the shipping cost, w is the weight, m and b are non-zero constants.
By using the set of data in the table, what we can do is to substitute the corresponding values into our general equation. [Use any 2 set of numbers]
11 = 4w + b --(1)
17 = 8w + b --(2)
Here we got 2 equations, 2 unknown, thus we can get
w = 3/2, b = 5
The answer is c, C=1.5w + 5
[Noted that if you already got the slope(the yellow words), you can simply substitute one set of numbers into C=1.5w + b to find the value of b]

write the equation of a line that has a slope of 3x - 4y = 12 and passes through the point (8, 8)
Answers
3x - 4y = 12
-4y = 12 - 3x
y = -3 + ³/₄ x
y = ³/₄x - 3
so the slope is ³/₄
now the equation is :
y-y₁ = m (x-x₁)
y-8 = ³/₄ (x-8)
y-8 = ³/₄ x - 6
y = ³/₄ x -6 + 8
y = ³/₄x + 2

which of the following is the correct factorization of the trinomial below -7x^2+5x+12
Answers
It’s always good to know the several ways to solve these problems, but one of the easiest and fastest would be the box method.
The box method involves you finding you a, b, and c values in a quadratic equation. It goes as follows, Ax^2+bx+c. When doing the box method, you multiply only your A and c. In this case -7*12 which gives you -84. Next you just find you b value (which is 5).
Now comes the trick part, you need to find the factors of -84 that ADD UP to equal 5. Therefore we just find the factors of 84 by listing them (find them for 84 then determine with the negative later). So we have 2, 42/ 3,28/ 4/21/ 6,14 / and 7,12. It becomes easier to find your factor, but 7 and 12 can equal to 5 in this condition due to 84 being negative, therefore one of the factors will be negative. By making 7 negative we can make 12+-7 equal to our b value of 5.
Now that we have the factors, we put them into fractions. We put them in the form that a would be on top and the factor would be on the bottom. Therefore a/(factor). In this case is would be -7/12 and -7/-7. With these fractions, we then simplify as much as we can, -7/12 cannot be simplified so it stays the same, but -7/-7 can be simplified to 1/1.
These fractions then become you FACTORS of your quadratic equation, in which case the a value in the fraction adds x to it, therefore it would be -7x+12 and x+1. The correct would would be (-7x+12)(x+1).

The cost and revenue functions are in that order and , where is the total number of mowers produced and sold each day. How many units must be manufactured and sold each day for the company to break even?
Answers
Answer:
120
Step-by-step explanation:
The break-even point is the point where revenue =cost
48,000+ 1400x = 1800x
48000=400x
X=48000/400
X=120
Equilibrium quantity is 120 mowers

Answers
The supplementary angle of 47 degrees is 133 degrees
Answer:
A.) complement, 43°; supplement, 133°
Step-by-step explanation:
A compliment angle is any angle(s) that adds up to 90°
A supplement angle is any angle(s) that adds up to 180°
For compliment:
90 - 47 = 43
For supplement:
180 47 = 133
Therefore, the answer would be A.

A Pizza factory has come out with two kinds of pizzas.A square pizza of side 26 cm costs AED 80 and a circular pizza of diameter 28cm costs AED 80. Which pizza is a better deal? Justify your answer.[=227].
Answers
Answer:
Square pizza
Step-by-step explanation:
To obtain which pizza is the best buy:
Cost of square pizza :
AED 80
side length, s = 26cm
Area of square, A = s²
A = 26² = 676 cm²
1 AED of square pizza gives : 676 / 80 = 8.45 cm²
Cost of circular pizza :
AED 80
Radius, r = 28cm
Area of circle, A = πr²
A = 22/7 * 14 * 14 = 22 * 2 * 14 = 616 cm²
1 AED of circular pizza gives : 616 / 80 = 7.7cm²
Hence, square pizza is the better buy ;
8.45cm² > 7.70 cm²

Answer:
slope: 45y-intercept: 30equation: y = 45x + 30Step-by-step explanation:
The slope is the cost per month. (A slope is often expressed as a ratio: dollars per month, in this case.) The slope is 45.
The y-intercept is the value that obtains when the number of months (in this case) is zero. It is the activation fee, 30. The y-intercept is 30.

The equation in slope-intercept form is ...
y = mx + b . . . . . where m is the slope and b is the y-intercept
Using the above numbers, the equation is ...
y = 45x + 30

Answers
Answer:
An exponential function is given by;
f(x)=ba^x
where a is any value greater than 0,
b is the intial value
when a>1 then f(x) is defined as an exponential growth
when a<1 then f(x) is defined as an exponential decay
From the our function;
f(t)=15000(0.86)^t
a=0.86<1
b=15000
since a<1, the function will be an exponential decay.
