Answer:
The equation of the linear function is y = 3x + 3
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slopeb is the y-interceptThe rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points on the line∵ A line passes through points (1, 6) and (2, 9)
∴ x1 = 1 ad y1 = 6
∴ x2 = 2 and y2 = 9
→ Use the rule of the slope above to find the slope of the line
∵ m = [tex]\frac{9-6}{2-1}[/tex] = [tex]\frac{3}{1}[/tex] = 3
∴ m = 3
→ Substitute the value of m in the form of the equation above
∴ y = 3x + b
→ To find b substitute x and y in the equation by the coordinates of any
point on the line
∵ x = 1 and y = 6
∴ 6 = 3 (1) + b
∴ 6 = 3 + b
→ Subtract 3 from both sides
∵ 6 - 3 = 3 - 3 + b
∴ 3 = b
→ Substitute the value of b in the equation above
∴ y = 3x + 3
∴ The equation of the linear function is y = 3x + 3

Annabelle is ordering a taxi from an online taxi service. The taxi charges $2 just for the pickup and then an additional $1.50 per mile driven. How much would a taxi ride cost if Annabelle is riding for 6 miles? How much would a taxi ride cost that is mm miles long?
Answer:
$11Step-by-step explanation:
Step one:
given
Taxi charges =$2
Additional charges =$1.50 per mile driven
Step two:
Required
The cost of the ride for a 6miles long drive
let the number of miles be x
and the total charges be y
The cost function is expressed as
[tex]y=1.5x+2[/tex]------------1
hence for x=6
y=1.5(6)+2
y=9+2
y=11
Therefore the cost of a 6miles drive will be $11

1) h(x) = -3x + 5; Find h(-1-2)
Answer:
h(-1) = 8
h(-2) = 11
h(-12) = 41
Step-by-step explanation:
h(x) = -3x + 5
h(-1) = -3(-1) + 5 = 3 + 5 = 8
h(-2) = -3(-2) + 5 = 6 + 5 = 11
h(-12) = -3(-12) + 5 = 36 + 5 = 41

Solving systems of equations using substitution/eliminationStep-by-step explanation:
Step 1: Define systems
5x - 2y = 9
3x + 4y = -5
Step 2: Rewrite systems
10x - 4y = 18
3x + 4y = -5
Step 3: Solve for x
Add to equations together: 13x = 13Divide 13 on both sides: x = 1Step 4: Solve for y
Define: 3x + 4y = -5Substitute in x: 3(1) + 4y = -5Multiply: 3 + 4y = -5Isolate y term: 4y = -8Isolate y: y = -2And we have our final answer!
symbolize is the use of a symbol to:
A(describe a character)
B(represent an abstract idea)
C(represent a concrete thing)
D(compare two different things)
Answer:
B(represent an abstract idea)
Step-by-step explanation:
A symbol is a stylistic figure whose essence is to use a word or phrase to refer to another, usually abstract term, to which it refers.
What symbolism means in every sphere is precisely the reference by one term to another term that symbolizes.
A symbol consists of a concrete material designation which refers to some abstract concept.

FIND THE QUADRATIC FUNCTION DETERMINED BY EACH TABLE
X -2 -1 0 1 2 3
Y 4 0 -2 -2 0 4
Answer:
x² - x - 2 = 0
Step-by-step explanation:
plotting the graph of x and y,we have that the root of the equation is -1 or 2
x = -1 or 2
the eqn therefore is;
x² - (sum of the root)x + (product of the root) =. 0
x² - (-1+2)x + (-1*2) = 0
x² - x - 2 = 0
Applying the Factor Theorem, it is found that the quadratic function is:
[tex]p(x) = x^2 - x - 2[/tex]
------------------------
The Factor Theorem states that if a polynomial [tex]p(x)[/tex] has roots [tex]x_1, x_2, ..., x_n[/tex], it is described by the following equation:
[tex]p(x) = a(x - x_1)(x - x_2)...(x - x_n)[/tex]
In which a is the leading coefficient.
For this quadratic function, the roots are [tex]x_1 = -1, x_2 = 2[/tex], as [tex]y(-1) = y(2) = 0[/tex], thus:[tex]p(x) = a(x - (-1))(x - 2)[/tex]
[tex]p(x) = a(x + 1)(x - 2)[/tex]
[tex]p(x) = a(x^2 - x - 2)[/tex]
When x = 0, p(x) = -2, and we use this to find a.
[tex]p(x) = a(x^2 - x - 2)[/tex]
[tex]-2 = a(0^2 - 0 - 2)[/tex]
[tex]2a = 2[/tex]
[tex]a = \frac{2}{2}[/tex]
[tex]a = 1[/tex]
Thus, the quadratic function is:
[tex]p(x) = x^2 - x - 2[/tex]

In a right triangle, measure of one of the acute angles is 10 degrees more than 3 times the measure of the other angle. What are the measures of the three
angles?
Answer:
How do you find the angle of a right triangle with 3 sides?
Step-by-step explanation:
Step 1 The two sides we know are Adjacent (6,750) and Hypotenuse (8,100).
Step 2 SOHCAHTOA tells us we must use Cosine.
Step 3 Calculate Adjacent / Hypotenuse = 6,750/8,100 = 0.8333.
Step 4 Find the angle from your calculator using cos-1 of 0.8333:

Can someone help me with systems of equations, (graphically)
Answer:
Step-by-step explanation:
You would use -6 and 7 to start your line. With the equation “y=5/6x+7", you would put a dot on 7. Then you would use the 5/6 to start making your line. With fractions, it's always rise/run. Starting from 7, you go up 5 then over(right) 6 until you run out of room on the graph. Then you do the opposite, down 5 then back(left) 6. Then you should have your first line. Then repeat that for the next equation. Start at -6, go down 4 and back three until you run out of room on the graph, then do the opposite. Go up 4 and over 3.
