Answer:
line L is not parallel to AB
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
3y = 4 - 2x ( divide terms by 3 )
y = [tex]\frac{4}{3}[/tex] - [tex]\frac{2}{3}[/tex] x ← in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]
Calculate slope of AB using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = A(1, 3) and (x₂, y₂ ) = B(- 2, - 1)
[tex]m_{AB}[/tex] = [tex]\frac{-1-3}{-2-1}[/tex] = [tex]\frac{-4}{-3}[/tex] = [tex]\frac{4}{3}[/tex]
Parallel lines have equal slopes
Since the slopes are not equal then the lines are not parallel

Answer: The first one is y≤11 and the second question is x>16 Hope that helps Goodbye!
Step-by-step explanation: 1. Add 22 to both sides.
-13+2
−y≥−13+2
2 Simplify -13+2−13+2 to -11−11.
-y\ge -11
−y≥−11
3 Multiply both sides by -1−1.
y\le 11
y≤11
1 Add 22 to both sides.
6+2<\frac{x}{2}
6+2<
2
x
2 Simplify 6+26+2 to 88.
8<\frac{x}{2}
8<
2
x
3 Multiply both sides by 22.
8\times 2<x
8×2<x
4 Simplify 8\times 28×2 to 1616.
16<x
16<x
5 Switch sides.
x>16
x>16
8p²-18p² need help from brainliest
Answer:
- 10p2
Step-by-step explanation:
p(8p - 18 p)
p x -10p
ans = -10p2
Answer: -10p²
This is the same as saying -10p^2
============================================
Explanation:
Both terms 8p² and -18p² are like terms.
We combine them in much the same way as 8-18 = -10, just with a p² attached to everything.
So 8p² - 18p² = (8-18)p² = -10p²
The coefficient -10 is negative because we're subtracting small minus big. If it was the other way around, then we'd get a positive value.

Write an equation that represents the line.
Use exact numbers.
Answer:
y = 3/4 x - 9/2
Step-by-step explanation:
Slope = 3/4
y = mx + b
y = 3/4x + b
0 = 3/4 (6) + b
0 = 18/4 + b
-9/2 = b
y = 3/4 x - 9/2

Answers:
a = 475r = -0.5f(3) = 59.4=======================================================
Explanation:
Any exponential function is of the form y = a*b^x
Comparing that to y = 475*(0.5)^x, we see that a = 475 and b = 0.5
Set b equal to 1+r and solve for r
1+r = 0.5
r = 0.5-1
r = -0.5
The negative r value tells us that the growth rate is -50%, in other words, we have a 50% decay rate. The amount drops by 50% each time x goes up by 1. This is the same as saying the amount cuts in half each time x goes up by 1.
-----------------------
Lastly, plug in x = 3 to find f(3)
f(x) = 475(0.5)^x
f(3) = 475(0.5)^3
f(3) = 59.375
f(3) = 59.4

Find the missing side of the triangle and leave the answer in simplest radical form.
Answer:
x = [tex]\sqrt5[/tex]
Step-by-step explanation:
Using Pythagoras theorem,
Square of longer side = Sum of square of other sides .
Therefore,
[tex](\sqrt{11})^2 = x^2 + (\sqrt{6})^2\\\\11 = x^2 + 6\\\\11 - 6 = x^2\\\\5 = x^2\\\\x = \sqrt 5[/tex]
Answer:
x = √5.
Step-by-step explanation:
By Pythagoras:
x^2 = (√11)^2 - (√6)^2
x^2 = 11 - 6 = 5
x = √5.

if 3/2+x/3=11/6,find x .
Step-by-step explanation:
[tex] \frac{3}{2} + \frac{x}{3} = \frac{11}{6} [/tex]
[tex] \frac{x}{3} = \frac{11}{6} - \frac{3}{2} [/tex]
[tex] \frac{x}{3} = \frac{11 - 3 \times 3}{6} [/tex]
[tex] \frac{x}{3} = \frac{11 - 9}{6} [/tex]
[tex] \frac{x}{3} = \frac{2}{6} [/tex]
[tex] \frac{x}{3} = \frac{1}{3} [/tex]
[tex]x = \frac{3 \times 1}{3} [/tex]
[tex]x = 1[/tex]
Answer:
x = 1
Step-by-step explanation:
3/ 2 + x/ 3 = 11/ 6
taking LCM
(9 + 2x)/ 6 = 11/ 6
multpiying both sides by 6
9 + 2x = 11
subtracting btih sides by 9
2x = 11 - 9
2x = 2
dividing both by 2
x = 1

If the area is 30cm and the length is 13,23 cm., what will be the width in
cm?
Answer:
ok so the standard equation for finding the area of a equation is BH=A
so if the lenth is 1323 and the width is unknown other wise X
we can make an equation
1323X=30
so we divide 30 by 1323 which is
X=0.02267573696 so
The width is about 0.023 cm

Instructions: Find the slope of the line through the points (-13, 16) and (-13, 12). Make sure to simplify
fractions and enter your answers with a foward slash (i.e. "/"). If the slope is undefined enter "undefined.
Answer: undefined
Step-by-step explanation:
Using the slope formula: (y^2 - y^1)/(x^2 - x^1), we can fill in the points:
(12 - 16)/(-13 - - 13) = -4/0
We can’t have a denominator of zero, so this is undefined.

Step-by-step explanation:
It costs a homeowner $4.00 to rent a set of hand tools, plus an additional
$2.00 per hour for the rental. The function that models the cost, c, of renting
tools for h hours is c = 2h + 4.
On a piece of paper, graph the function. Then determine which answer choice
matches the graph you drew.
Answer:
The correct graph answer is A.
Step-by-step explanation:
Let
c ----> the total cost to rent a set of hand tools
h ----> the number of hours for the rental
we know that
The linear equation that represent the problem is equal to
---> this is the equation of the line into slope intercept form
where
the slope m is equal to
m=$2 per hour
b=$2 ---> the y-intercept (the value of c when the value of h is equal to zero)
therefore
The correct graph is A.
B. C. and D. are incorrect
