Given:
The value of the function g(x) is −2 when x=−5 and is 5.7 when x=6.
To find:
The equation of the function.
Solution:
The value of the function g(x) is −2 when x=−5. It means the graph of function passes through (-5,-2).
The value of the function g(x) is 5.7 when x=6. It means the graph of function passes through (6,5.7).
The equation of function g(x) that passes through (-5,-2) and (6,5.7) is
[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]
[tex]y-(-2)=\dfrac{5.7-(-2)}{6-(-5)}(x-(-5))[/tex]
[tex]y+2=\dfrac{5.7+2}{6+5}(x+5)[/tex]
[tex]y+2=\dfrac{7.7}{11}(x+5)[/tex]
[tex]y+2=0.7(x+5)[/tex]
[tex]y+2=0.7x+3.5[/tex]
Subtract 2 from both sides.
[tex]y=0.7x+3.5-2[/tex]
[tex]y=0.7x+1.5[/tex]
Therefore, the equation of function g(x) is [tex]y=0.7x+1.5[/tex].
A website sells sweaters. The amount of sales p(c) varies directly with the number of customers c. Eight customers bought a total of $335 worth of sweaters. Which equation can be used to find the sales for c customers? p(c) = 41.88c p(c) = 4188c p(c) = 41.88c p(c) = 4188c
Answer: p(c) = 41.88c
Step-by-step explanation:
From the question, we are informed that a website sells sweaters and that the amount of sales p(c) varies directly with the number of customers c.
We are further told that eight customers bought a total of $335 worth of sweaters.
The equation that can be used to find the sales for c customers will be:
= 335/8
Therefore, the answer is p(c) = 41.88c
= 41.88

Answer:
Step-by-step explanation:
35% means 35 per hundred. 35/100. simplify and write as 7/20.
0.64 means its 2 zeros left of regular number. 64/100.
82% means 82 per hundred. 82/100. move decimal 2 spaces to left (division is left, multiplication is right). 0.82.
4/5. try to make denominator 100. multiply both numerator and denominator by 20. 80/100. move decimal 2 spaces to the left. 0.8.
14/50. try to make denominator 100. multiply both numerator and denominator by 2. 28/100. 28%
0.19 can be written as 19/100. 19%
Answer: 35%=7/20 0.64=64/100. 82%=82/100. 4/5=0.8 14/50=0.28 0.19=19%

2). The ordered pairs all lie on the same line. Using the ordered pairs, write
an equation of the line in the form y = mx + b.*
(0, 3) (2, 7) (-1, 1) (5, 13)
Answer:
y = 2x + 3
Step-by-step explanation:
First things first we have to find the slope. To do so you simply choose two of the ordered pairs and use the formula:
y2 - y1 / x2 - x1
I will use (0, 3) and (2, 7).
7 - 3 / 2 - 0
4 / 2
2
let’s double check by using the other set of ordered pairs.
(-1, 1) and (5,13)
13-1 / 5 + 1
12 / 6
2
Our slope is 2!
Next we will use the point-slope formula:
y - y1 = m (x - x1)
we will do this with one of the ordered pairs, since they all lie on the same line the answer will be the same each time.
I will use (2, 7).
y - 7 = 2(x - 2)
distribute:
y - 7 = 2x - 4
add 7 to both sides:
y = 2x + 3
Just to be sure that i didn’t make any mistakes i will double check by using another ordered pair.
I will use (-1, 1)
y - 1 = 2 (x + 1)
distribute:
y - 1 = 2x + 2
add 1 to both sides
y =2x + 3
There we have it! The answer is:
y = 2x+ 3

then select none.
When m_1= m_D
O AB II DC
AD || BC
none
Answer:
it is AD l l DC so ots B
Step-by-step explanation:
Answer
If the line segment AB is parallel to the line segment DC then, m∠1=m∠D by corresponding angles.
What is corresponding angle?Congruence and similarity tests in geometry involve comparing corresponding sides and angles of polygons.
Each side and angle in one polygon is paired with a side or angle in the second polygon, with the order of adjacency preserved.
One is an exterior angle (beyond the parallel lines), while the other is an interior angle (inside the parallel lines).
Corresponding angles and transversal lines are defined. Corresponding angles are a subset of angle pairs. Angles on the opposite side of the transversal are referred to as alternate angles.
If line segment AB is parallel to line segment DC,
m∠1=m∠D, by corresponding angles
If line segment AD is parallel to line segment BC,
m∠3=m∠B, by corresponding angles
Thus, this can be concluded regarding the given scenario.

An apprentice baker made 40 liters of 60% sugar syrup instead of 40 liters of 45% sugar syrup. How much syrup should she drain and replace with distilled water so that the resulting solution is 40 liters of 45% syrup?
Answer:
10 lStep-by-step explanation:
40 l of 60% sugar syrup becomes 40 l of 45% sugar syrup if x l is drained and replaced with distilled water. Sugar content is then:
(40 - x)*0.6 = 40*0.4524 - 0.6x = 180.6x = 24 - 180.6x = 6x = 6/0.6x = 10 l10 liters solution was replaced with distilled water
