3. What is the slope and the y-intercept of
the line represented by equation:
2x + y = 1?
Explanation:
Answer:
The slope is -2/1 or simplified -2 and the y-intercept is 1
Step-by-step explanation:
Answer: Slope:-2 and y-intercept:1
Step-by-step explanation:
y=1 because the y by itself means 1.
The slope is a -2 because you have to do the opposite.

Consider the equation 1.5x+4.5y=18. For each question, explain or show your reasoning.
Where does the graph intersect the y-axis (answer should be an ordered pair)?
Given:
The equation is
[tex]1.5x+4.5y=18[/tex]
To find:
The y-intercept (in ordered pair).
Solution:
We have,
[tex]1.5x+4.5y=18[/tex]
Putting x=0, we get
[tex]1.5(0)+4.5y=18[/tex]
[tex]0+4.5y=18[/tex]
[tex]4.5y=18[/tex]
Divide both sides by 4.5.
[tex]y=\dfrac{18}{4.5}[/tex]
[tex]y=4[/tex]
So, y-intercept is 4.
Therefore, the graph intersect the y-axis at (0,4).
please help me with this, thank you so much!!

hot air balloon is attached to the ground by a cable that is 200 meters long. The cable makes a 57° angle with the ground.
How many meters above the ground is the balloon if there is no slack in the cable? Round your answer to the nearest tenth of a meter
Answer:
Let C be the position of the meteorological station, B the position of the balloon and CB be the cable.
Let the height of the balloon from the ground be AB=hmetres.

∴h=100×1.732=173.2 since

=1.732
Hence, the height of the balloon above the ground is 173.2m
By inscribing the given information in a right triangle, we will see that the ballon is 167.7 meters above the ground.
Think in the situation as in a right triangle, you have a hypotenuse that is equal to the length of the cable, you know one angle of 57°, and the opposite cathetus to this angle represents the height at which the ballon is, this is what we want to find.
Using the relation:
sin(θ) = (opposite cathetus)/hypotenuse.
Where:
θ = 47°hypotenuse = 200mopposite cathetus = height.Replacing that we get:
sin(57°) = height/200m
sin(57°)*200m = height = 167.7m
So the balloon is 167.7 meters above the ground.

Find the angle measures.
Justify your responses.
Given: a//b, m1 = 71 degrees
Find: m5 , m8
SHOW YOUR WORK OR I WILL NOT GIVE YOU BRAINLIEST ANSWER! THANK YOU
Answer:
The measure of angle MNP is
m ∠ MNP = (x - y)/2
Explanation:
The image attached shows the figure corresponding to this question.
The angle MNP, which is also the angle LNP, is formed by the intersection of a secant and a tangent to a circle.
Then, you can use the theorem:
the angle formed by a secant and a tangent to a circle that intersect outside the circle is half the difference of the major arc minus the minor arc.
The major arc formed is identified with the letter x and the minor arc is identified with the letter y. Thus, the measure of the angle MNP is half the difference x - y:
m ∠ MNP = (x - y)/2

In one year, Linda's parents spend $2400 on cable and internet service. If they spend the same amount each month, what is the resulting monthly change in the family's income? *
Answer: $200
Step-by-step explanation:
Given: In 1 year ,
Linda's parents spend $2400 on cable and internet service.
If they spend the same amount each month, Monthly payment = [tex]\dfrac{\text{Total money spent in 1 year}}{\text{Number of months in a year}}[/tex]
[tex]=\dfrac{\$2400}{12}\ \ \ [\text{Number of months in a year}=12]\\\\=\$200[/tex]
Hence, the resulting monthly change in the family's income = $200

The solution is, The way to write the rule is: (x, y) is (x – 3, y + 5).
A triangle which is on a coordinated plane is translated to the rule.
What is coordinate plane?Two lines combine to generate the two-dimensional surface known as the coordinate plane. The x-axis is a single horizontal number line. The y-axis is the name of the vertical number line that is the other number line.

Right so, you would first graph your center point. Then, based on the radius, you would make four points. Let's say your center point is (0,0) and your radius is 2. You would make a point at (-2,0), (2,0), (0,-2), and (0,2). You would then draw a circle through those points. Let me know if you need any further clarification!

1) Albert has $200 in the bank. He would like to save $50 every month to buy Christmas
gifts. Which equation can be used to find y, the amount Albert will save for x days?
y = 50x + 200
y = 50 + 200x
y = 250x
y = 200 + 250x
Answer:
y = 50x + 200
Step-by-step explanation:
He has $200 at the bank. He is then adding 50 per month (that's why its 50x).
