Answer:
1) y = -1.5x - 1 || 2) y = -1.5x + 1 || 3. D ( 2 , -8 )
Step-by-step explanation:
1)
two coordinates: ( 0 , -1 ) , ( 2 , -4 )
slope = ( y2-y1 )÷(x2-x1) = (-4--1)÷(2-0) = -1.5
then find equation using: y - y1 = m ( x - x1 )
: y - - 1 = -1.5 ( x - 0 )
: y = -1.5x - 1
2)
two coordinates: ( 0 , 1 ) , ( -2 , 4 )
slope = ( 4 - 1) ÷ (-2-0) = -1.5
Find equation using y = mx +b ........where m is slope and b is y-intercept
y = -1.5x + 1
3)
y + 8 = 3(x -2 )
y = 3x -14 ..........main equation in slope intercept form.
A)
y = 3(-2)-14
y = -20 .therefore option A is incorrect
B)
y = 3(8)-14
y = 10 .therefore option B is incorrect
C)
y = 3(-8)-14
y = -38.therefore option C is incorrect
D)
y = 3(2)-14
y = 6 -14
y = -8 . therefore it matches and is correct answer.
the line crosses D( 2 , -8 )

10) (3, 4), (-4,-5)
11) (-20, 14), (17, 15)
12) (11, -18), (-1, -7)
Helpppp
Slope = (y2-y1) / (x2-x1)
9) (7 - -6)/(-11- 17) = 13/-28
10) (-5-4)/(-4-3)= -9/-7
11) (15-14)/(17- -20) = 1/37
12) (-7 - -18) /(-1 -11) = 11/-12
Evaluate the expression when t = 0.2.
300t2−0.5÷t
the 2 after the t is an exponent
Answer:
9.5
Step-by-step explanation:
Just put the 0.2 in the correct.
We know that:
t = 0.2Given expression: 300t² − 0.5 ÷ tNow, let's solve the given expression.
300t² − 0.5 ÷ t=> 300 x 0.2² − 0.5 ÷ 0.2=> 300 x (2/10 x 2/10) − (5/10 x 10/2)=> 300 x (4/100) − (5/2)=> 300 x 4/100 − 5/2=> 3 x 4 − 5/2=> 12 - 5/2=> 12 - 2.5=> 9.5Hence, the solution is 9.5.

➡️Sqdancefan sir please solve this questions.
Thank you.
Answer:
20. $3,600
21. $32,400
22. $626.38
23. $41,182.80
Step-by-step explanation:
20.The down payment is 10% of the purchase price, so is ...
amount down = 10% × $36,000 = 0.10 × $36,000
amount down = $3,600
__
21.The amount financed is the remaining amount due:
$36,000 -$3,600 = $32,400
__
22.The monthly payment is found from the amortization formula.
A = P(i/12)/(1 -(1 +i/12)^(-12t)) . . . . P is the amount financed at rate r for t years
A = $32,400(0.06/12)/(1 -(1 +0.06/12)^(-12×5))
A = $32,400(0.005)/(1 -(1.005^-60)) ≈ $626.38
Samantha's monthly payment will be $626.38.
__
23.The total amount paid is ...
total paid = down payment + monthly payment × number of months
total paid = $3,600 +626.38×60 = $41,182.80
The total amount Samantha will pay is $41,182.80.

Which system of equations does this graph represent?
Answer:Two solution
Step-by-step explanation:
System of the equations consists of a straight line and parabola will be [tex]y = x - 4[/tex] and [tex]y = x^{2} + 4[/tex].
What is system of equation?" A system of equations is a finite set of equations for which we find the common solution."
According to the question,
Y - intercept of line = ( 0, -4)
X - intercept of line = ( 4 , 0)
Standard equation for straight line y = mx +c
m = slope
c = y - intercept
Slope of the line 'm' = [tex]\frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
= [tex]\frac{0-(-4)}{4-0}[/tex]
= [tex]\frac{4}{4}[/tex]
= 1
y- intercept 'c' = - 4
Substitute the value to get the equation of line we get,
Equation of the line y = x - 4
For equation of parabola,
Standard equation of parabola y = (x-h)² + k
Vertex (h, k) = ( 0,2)
Substitute the value of the vertex we get,
y = (x-0)² + 2
⇒y = x² + 2
Hence, system of the equations consists of a straight line and parabola will be [tex]y = x - 4[/tex] and [tex]y = x^{2} + 4[/tex].

Step-by-step explanation:
we can find the value of c by Pythagoras theorem
according to Pythagoras theorem
h² = a² + b²
where
h = hypotenuse (i.e. longest side of a right angled triangle)
a = side
b = base
so, we have to find h or hypotenuse here
h² = (24)² + (18)²
h = 576 + 324 = 900
h² = √900 = 30
c = 30
therefore, value of c is 30.

Equivalent expressions are expressions with equal values
The equivalent expression of (3x - 2)(2x - 3) is 6x^2 - 13x + 6
The expression is given as:
(3x - 2)(2x - 3)
Open the bracket
(3x - 2)(2x - 3) = 6x^2 - 9x - 4x + 6
