Y=-5X+1
Step-by-step explanation:
Answer:
y = -5x + 1
Step-by-step explanation:
y = mx + b
m = [tex]\frac{y_{2}- y_{1} }{x_{2}- x_{1}}[/tex] = [tex]\frac{-9-(-4)}{2-1} = -5[/tex]
y = -5x + b: then plug in a point to find b
-19 = -5(4) + b
-19 = -20 + b
b = 1
Plug in all the values to get: y = -5x + 1

Melanie has a bag that contains orange chews, cherry chews, and peach chews. She performs an experiment. Melanie randomly removes a chew from the bag, records the result, and returns the chew to the bag. Melanie performs the experiment 61 times. The results are shown below: A orange chew was selected 38 times. A cherry chew was selected 5 times. A peach chew was selected 18 times. Based on these results, express the probability that the next chew Melanie removes from the bag will be peach chew as a decimal to the nearest hundredth.
Answers
Answer:
0.30
Step-by-step explanation:
Given that:
Total number of trials = 61
Number of orange chews = 38
Number of cherry chews = 5
Number of peach chews = 18
Probability that next chew removed will be a peach chew ;
This is an experimental probability problem ;
Using the relation :
Experimental probability of A;
Number of successes (A) / total number of trials
Hence, Probability that next chew removed will be a peach chew ;
Experimental probability of peach chew :
Number of trails = 61 ; number of successes (peach chew) = 18
P(peach chew) = 18 / 61
P( peach chew) = 0.2950819
= 0.30 ( nearest hundredth)

Jared has 12 more comic books than Zoe. If they have 28 comic books
altogether, find the number of comic books Jared has.
Your answer
Answers
Answer:
20 comic books
Step-by-step explanation:
Let us first set up a variable, x, for the number of books that Zoe has. If Jared has 12 more comics than Zoe, he would have x+12 books.
Given that Zoe and Jared have a total of 28 comic books, let us write an equation and solve for x:
[tex]x+x+12=28\\2x+12=28[/tex]
Now that we have a simplified version of the equation, let us solve for x by isolating the variable on the left side:
[tex]2x=28-12\\2x=16\\x=8[/tex]
We now know that x=8, and also that Jared has x+12 books. To find the number of comic books Jared has, let us add 12 to x:
[tex]x+12=\\8+12=\\20\\[/tex]
Therefore, Jared has 20 comic books.
I hope this helps! Please let me know if you have any further questions :)

Step-by-step explanation:
Slope (x) is rise/run. From one intersecting point to the next, we find it is moving 4 y down and 1 x over. Using this we conclude the slope is -4/1x (or -4x)
The second number in the system is b, or y-intercept. The line intercepts at 4y. If we combine these together, the outcome is y = -4x + 4

Step-by-step explanation:
Answer:
Multiply both the numerator and the denominator by the same whole number.
For example;
If you multiply 1/2 by 2/2, this will equal 2/4. You can simplify 2/4 to 1/2.
So to find 1/2 to be equivalent to another fraction, multiply both the numerator and the denominator by the same number to find a fraction that equals 1/2.

Because of prevailing winds, a tree grew so that it was leaning 6º from the vertical. At a point d = 37 meters from the tree, the angle of elevation to the top of the trees

Answers
Answer:
Height of the tree is 40.0 meters.
Step-by-step explanation:
From ΔABC,
m∠ABC = 90°
Since, m∠ABC = m∠CBD + m∠ABD
90° = 6° + m∠ABD
m∠ABD = 90°- 6° = 84°
By triangle sum theorem in ΔABD,
m∠ABD + m∠BDA + m∠DAB = 180°
84° + 29° + m∠BDA = 180°
m∠BDA = 180° - 113°
= 67°
By sine rule in ΔABD,
[tex]\frac{\text{sin}(\angle BDA)}{d}= \frac{\text{sin}(\angle ABD)}{h}[/tex]
[tex]\frac{\text{sin}(67)}{37}= \frac{\text{sin}(84)}{h}[/tex]
h = [tex]\frac{\text{sin}(84)\times 37}{\text{sin}(67)}[/tex]
h = 39.98
h ≈ 40.0 meters
Therefore, height of the tree is 40.0 meters.
The sine rule is the ratio of the side length to the sine of the opposite angles. Then the height of the tree is 40 meters.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a triangle.
Because of prevailing winds, a tree grew so that it was leaning 6º from the vertical.
At a point d = 37 meters from the tree, the angle of elevation to the top of the trees is a = 29° (see figure).
∠ABC = 90
We have
In ΔABC
∠ABC = ∠CBD + ∠ABD
∠ABD = 90 - 6
∠ABD = 84
By triangle sum in ΔABD, we have
∠ABD + ∠BDA + ∠DAB = 180
∠BDA = 180 - 84 - 29
∠BDA = 67
Then by the sine rule, we have
[tex]\begin{aligned} \dfrac{\sin \angle BDA}{d} &= \dfrac{ \sin \angle ABD }{h}\\\\\dfrac{\sin 67}{37} &= \dfrac{\sin 84}{h}\\\\h &= \dfrac{\sin 84} \times 37{\sin 67}\\\\h &= 39.98 \approx 40 \end{aligned}[/tex]

Enter equations one at a time in order to send a line
through the coins to "capture" them.
Answers
Answer:
y = x + 3
y = 3x + 1
Step-by-step explanation:
This does it in two equations.
y = x + 3 and y = 3x + 1 equation will send 2 different lines through the coins to capture them
using the slope intercept equation,
y = mx + b
m = slope
b = y-intercept
let's pick 2 coordinate from the graph,
(-2, 1)(-1, 2)
m = 2 - 1 / -1 - (-2) = 1 / 1 = 1
1 = -2 + b
b = 3
Therefore,
y = x + 3
let check for another equation that will work for another line. Let's use the coordinates (-1, -2)(0, 1) to find slope.
Therefore,
m = 1 - (-2) / 0 - (-1) = 3 / 1 = 3
y = 3x + b
1 = 3(0) + b
b = 1
y = 3x + 1
