1. Given the equation 3x – 4y = 24.
a) Find two solutions to the equation. Write your answer as coordinates.
b) Using your answers from part a, what is the slope of the given equation.
c) Convert the given equation into slope-intercept form.
Answer:
(0, -6) and (8, 0)
[tex]\dfrac{4}{3}[/tex]
[tex]y=\dfrac{3}{4}-6[/tex]
Step-by-step explanation:
(a) [tex]3x-4y=24[/tex]
Let [tex]x=0[/tex]
[tex]0-4y=24\\\Rightarrow y=-6[/tex]
Let [tex]y=0[/tex]
[tex]3x-0=24\\\Rightarrow x=8[/tex]
Two coordinates are (0, -6) and (8, 0)
(b) Slope is given by
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}\\\Rightarrow m=\dfrac{0-(-6)}{8-0}\\\Rightarrow m=\dfrac{3}{4}[/tex]
The slope of the equation is [tex]\dfrac{4}{3}[/tex]
(c)
[tex]3x-4y=24\\\Rightarrow 4y=3x-24\\\Rightarrow y=\dfrac{3}{4}-6[/tex]
The slope intercept form of the equation is [tex]y=\dfrac{3}{4}-6[/tex]

Which of the following types of numbers is irrational?
A.) a whole number
B.) fractions
C.) the number pi
D.) a decimal that terminates
Answer:
C
Step-by-step explanation:
the definition of an irrational number is an infinite decimal that has no repeating pattern. rational numbers can be converted into fractions.
A is incorrect because a whole number can be converted into a fraction.
ex: 1 is also 3/3
B is incorrect because the definition of a rational number is that it can be converted into a fraction.
D is incorrect because a terminating decimal can be made into a fraction.
ex: 4.5 is also 9/2
D)

A triangle has an area of 12 square units and a height of 8 units. Find its base.
Answer:
3
Step-by-step explanation:
b= 2 [tex]\frac{A}{Hb}\\[/tex] = 2 · [tex]\frac{12}{8}[/tex] = 3
Answer:
base= 3
Step-by-step explanation:
You need to work backwards to solve this problem
A= 1/2bh
with the information given, the equation should look like this:
12= 1/2b8
To get rid of the fraction, you flip it, and you multiply both sides by that (1/2 fliped is 2)
so 2* 12= 1/2b8 *2
-----------------------------------------------------------------------------
** You can see that the 1/2 and the two cancel each other out. This is why:
1/2* 2/1= 2/2
2/2=1
1 * b8 is just b8
----------------------------------------------------------------------------
So now you have:
24= b8
you want to get b by itself, so you use inverse operations ( you divide both sides by 8)
24/8= b8/8
your final answer is 3=b
you can plug in 3 into the original equation to check your answer!!!

Barry-
A truck driver has to make a delivery at
a location that is 230.2 miles away. She
drives an average of 55 miles each hour
for 3.25 hours. If the truck driver
continues at the same speed, will she
make it to the location in the next
hour?
A Yes, she only has 51.45 miles to go.
® Yes, she only has 52.55 miles to go.
© No, she still has 63.45 miles to go.
D No, she still has 64.65 miles to go.
Answer:
Option A is correct
Step-by-step explanation:
Speed of truck = 55 miles/hour
Time taken = 3.25 hours
Distance = Speed × Time
[tex]=55[/tex] × 3.25
[tex]=178.75[/tex]
But truck driver has to make a delivery at a location that is 230.2 miles away.
Distance left to be covered by a truck driver = [tex]230.2-178.75=51.45[/tex] miles
So,
Yes, if the truck driver continues at the same speed, she will make it to the location in the next hour such that she only has 51.45 miles to go.
Option A is correct
We want to see if the truck driver has enough speed to reach the destination or not. The correct option is A "Yes, she only has 51.45 miles to go."
Working with speeds:So we know that she needs to travel a total distance of 230.2 miles.
Now, remember the relation:
Speed*time = distance.
And she travels at an average speed of 55 miles per hour for 3.25 hours, so she traveled a distance of:
(55 mi/h)*3.25 h = 178.75 mi
Then the remaining distance is just:
230.2 mi - 178.75 mi = 51.45 mi
Will she make it in the next hour?
Well, yes, she travels at 55 miles per hour and she has 51.45 miles remaining, so yes, she will make it.
The correct option is A: "Yes, she only has 51.45 miles to go."

help find the slope of the line
Answer:
-3/5
Step-by-step explanation:
When finding the slope, think of it as rise/run.
Rise= up/down
run=left or right
So looking at the line, it is pointing towards -inf so the slope is negative
Then we look at 2 points.
i.e. (0,2) and (-5,5) and do the rise over run technique (or just subtract) and you get your answer!

Answer:
7) (f+g)(x) = 4^x +5x -5
8) (f-g)(x) = 4^x +x +5
Step-by-step explanation:
7) add the two expressions.
(f+g)(x) = f(x) +g(x) = (4^x +3x) +(2x -5)
(f+g)(x) = 4^x +5x -5
__
8) subtract g(x) from f(x).
(f-g)(x) = f(x) -g(x) = (4^x +3x) -(2x -5) = 4^x +3x -2x +5
(f-g)(x) = 4^x +x +5

Circle with center point A. Radius AB is drawn. Tangent line CD is drawn and intersects the circle at point B. Segment AC is drawn from the center point A through point E on the circle to point C on line CD. The lengths of segments are not provided.
BC =
Answer:
BC is 24 units
Step-by-step explanation:
Given that: AB = 7 units
EC = 18 units
From a sketch for the question, we have a triangle ABC. Such that:
AC = AE + EC
But,
AE = AB = 7 (radius of the circle)
So that,
AC = 7 + 18
= 25 units
Applying Pythagoras theorem to triangle ABC, we have:
[tex]/AC/^{2}[/tex] = [tex]/AB/^{2}[/tex] + [tex]/BC/^{2}[/tex]
[tex]25^{2}[/tex] = [tex]7^{2}[/tex] + [tex]/BC/^{2}[/tex]
[tex]/BC/^{2}[/tex] = 625 - 49
= 576
BC = [tex]\sqrt{576}[/tex]
= 24
Thus, BC is 24 units.
