Answer:
y = 9x - 15
Step-by-step explanation:
The given y = 9x - 5 is already in slope-intercept form. Any line parallel to this one has an equation that looks exactly the same except for the constant term. Call the new constant term 'C.'
Start with y = 9x - 5 and substitute the coordinates of the given point (-1, 6):
6 = 9(-1) + C, or
6 + 9 = C, or
C = 15
Then the equation of the line that passes through (-1, 6) and is parallel to y = 9x - 5 is
y = 9x - 15

PLEASE HELP GEOMETRY LAST QUESTION!!! SOLVE FOR X AND SHOW WORK!!
Answer:
Solution given:
here
base[b]=x
perpendicular [p]=9√3
hypotenuse [h]=y
we have
sin 30=p/h
1/2=9√3/y
y=18√3 or 31.176
again
cos 30°=b/h
√3/2=x/18√3
x=3×18/2=27
x=27
Simplify the expression and then substitute the given number for the variable. For expression 8a2+6b+9a2+9b2+3b, find the value if a=2,b=−1.
Answer: 68
Step-by-step explanation:
Simplifying the expression:
= 8a² + 6b + 9a² + 9b² + 3b
Collect like terms
= 8a² + 9a² + 6b + 3b + 9b²
= 17a² + 9b + 9b²
We then substitute a=2,b=−1.
= 17a² + 9b + 9b²
= 17(2)² + 9(-1) + 9(-1)²
= 68 -9 + 9
= 68
Find the size of the angle 3x.
3x=
Answer:
60 degrees
Step-by-step explanation:
a straight line is 180 degrees
2x= 120 degrees
x=60 degrees
Answer:
The value of x is 60°
Step-by-step explanation:
For a given Straight Line
We know that, The straight angle is an angle equal to 180°
So,
3x = 180
Divide by 3 from both side
3x/3 = 180/3
x = 60°
Thus, The value of x is 60°

2. The length of a rectangle is 18 centimeters and the width is 6 centimeters. A similar rectangle
has a width of 2 centimeters. What is the length of the second rectangle? (Sketch a picture)
Answer:
6
Step-by-step explanation:
I am unable to sketch a picture for you but I will do my best to help you understand. We know that our length of the first rectangle is 18 cm and the width is 6 cm. At the moment we don't need 18 so we'll put that to the side for now and focus on the width. We understand that in a second similar rectangle, the width is 2 centimeters. in order to find our scale, we must divide the larger width by the smaller width. This means we will divide 6cm by 2 cm. 6/2=3 This means that we also divide 18 by 3 since the similar rectangle is smaller and we are figuring out the missing side. After dividing 18 by 3 we should get an answer of 6. 18/3=6 Which means that our similar rectangle has a length of 6 cm and a width of 2 cm.
I also want to mention that similar rectangles are not the same rectangle however you can think of them as enlargerd/shrunk versions of the original rectangle. I hope this helps.

1) One baseball team won 20 games throughout their entire season. Of all their games, this
team won 62.5% of them. Given this, how many games in total did this baseball team play
Answer: 32 matches
Step-by-step explanation:
Let the games in total that the baseball team played be represented by x.
Based on the information given in the question, we can form an equation as:
62.5% × x = 20
62.5/100 × x = 20
0.625 × x = 20
0.625x = 20
x = 20/0.625
x = 32
The team played a total of 32 matches.
How do you find the distance between points (5,1), (4,0)?
Answer:
To find the hypotenuse, you would use the formula a^2 + B^2 = C^2
That is the formula for the pythagorean theorem.
I suggest you first plot it on a graph, then could the units on the sides that make up the legs.
When you plot it, the legs are both 1 unit.
so it would be, following the formula:
1^2 + 1^2 = c^2
1 x 1 + 1 x 1 = c^2
2 = c^2
Then you square root:
√2 = √c^2
1.41421356 = c
1.41421356 rounded to the nearest tenth is 1.4.
So the length of (5,1), (4,0) is ≈1.4
Devante buys 1/1/4 pounds of cashews 7 ounces of almonds and 3/4 pounds of pecans how much do the nuts weight in
Answer: [tex]39\ \text{Ounces}[/tex]
Step-by-step explanation:
Given
The amount of cashews is [tex]1\frac{1}{4}\ \text{Pounds}[/tex]
Amount of almonds [tex]7\ \text{ounces}[/tex]
The amount of pecans is [tex]\frac{3}{4}\ \text{Pounds}[/tex]
We know, [tex]1\ \text{Pound}=16\ \text{Ounces}[/tex]
Converting pounds to ounces and adding them
[tex]\Rightarrow 1\dfrac{1}{4}\times 16+7+\dfrac{3}{4}\times 16\\\\\Rightarrow \dfrac{5}{4}\times 16+7+3\times 4\\\\\Rightarrow 20+7+12=39\ \text{ounces}\ or\ \dfrac{39}{16}\ \text{Pounds}[/tex]
Thus, the nuts weigh [tex]39\ \text{Ounces}[/tex]
Johnny wants to know how many students in his school enjoy watching science programs on TV. He poses this question to all 26 students in his science class and finds that 75% of his classmates enjoy watching science programs on TV. He claims that 75% of the school's student population would be expected to enjoy watching science programs on TV. Is Johnny making a valid inference about this population? (5 points)
a
Yes, it is a valid inference because his classmates make up a random sample of the students in the school
b
Yes, it is a valid inference because he asked all 26 students in his science class
c
No, it is not a valid inference because he asked all 26 students in his science class instead of taking a sample from his math class
d
No, it is not a valid inference because his classmates do not make up a random sample of the students in the school
Answer: d. No, it is not a valid inference because his classmates do not make up a random sample of the students in the school
Step-by-step explanation: this i because there is a possible bias present in his population

To approach the runway, a pilot of a small plane must begin at 6 degrees,descent starting from a height of 1905 feet above the ground. To the nearest tenth of a mile, how many miles from the runway is the airplane at the start of this approach
Answer:
C. 3.5 mi
Step-by-step explanation:
Reference angle = angle of elevation
Angle of elevation = angle of depression = 6° (alternate angle theorem)
Hypotenuse = x
Opposite = 1905 ft
Apply trigonometric function SOH:
Sin 6° = Opp/Hyp
Sin 6° = 1905/x
x * Sin 6° = 1905
x = 1905/Sin 6°
x = 18,224.7 ft
Convert form feet to miles
1 mi = 5,280 ft
Therefore,
18,224.7 = 18,224.7/5,280
= 3.45164773 mi
≈ 3.5 mi (nearest mile)
