What is the value of 4x – 3y if x = 3 and y = 6?
Answer:
-6
Step-by-step explanation:
If x=3 and y=6, 4x-3y=-6 because 4x with x=3 makes the first number 12. 3y with y=6 makes the result 18, so now the equation is 12-18. 12-18=-6, so 4x-3y with x=3 and y=6 will equal -6.
Hopefully the answer and explanation helps!
Answer:
-6
Step-by-step explanation:
All you have to do is plug in the numbers. So it should look like 4(3) - 3(6). Now all you have to do is solve. 4 x 3 = 12. 3 x 6 = 18. Now subtract. 12 - 18 = -6

Which of the following is the best estimate of the measure of the angle the skateboard makes with the ground ?
Answer:
Correct choice: C. 74.5
Step-by-step explanation:
Trigonometric Ratios
In every right triangle (those who have an internal angle of 90°), the six trigonometric ratios are valid. They relate the other internal angles with the lengths of the triangle.
The skateboard, the wall, and the ground form a right triangle. We need to find the measure of the angle formed by the skateboard with the ground. Let's call it β. In a right triangle, the cosine of an angle is defined as
[tex]\displaystyle \cos\beta=\frac{\text{adjacent leg}}{\text{hypotenuse}}[/tex]
The adjacent leg of β is the side with length 8 in, and the hypotenuse is the length of the skateboard, 30 in, thus:
[tex]\displaystyle \cos\beta=\frac{8}{30}}=0.267[/tex]
Using a digital calculator we find:
[tex]\beta=\cos^{-1}(0.267)[/tex]
[tex]\beta=74.5^\circ[/tex]
Correct choice: C. 74.5

Answer:
Step-by-step explanation:
1) 2^2 + 2^2 = c^2
4 + 4 = c^2
8 = c^2
c = sqrt8
2) 2^2 + 3^2 = c^2
4 + 9 = c^2
13 = c^2
c = sqrt13
3) 10^2 + 4^2 = c^2
100 + 8 = c^2
108 = c^2
c = sqrt108
4) 1^2 + 5^2 = c^2
1 + 25 = c^2
26 = c^2
c = sqrt26
5) 3^2 + 1^2 = c^2
9 + 1 = c^2
10 = c^2
c = sqrt 10
6) 9^2 + 9^2 = c^2
81 + 81 = c^2
162 = c^2
c = sqrt162
Use the figure at the right. If JK = 2x + 12 and NO = 14, what is the value of x?
Answer:
X=8
Step-by-step explanation:
JK would equal 28, since it basically is double the side of that triangle. So now we have the equation, 2x+12=28. Now we solve using inverse operation. 28-12=16 and then 16 divided by 2 is 8, so x=8.
The required simplified value of x is 8, for the given triangle.
What is the midpoint?A midpoint is a point on the line whose distance from both ends of the line is equal.
What is the triangle?The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°
Here,
The property of a triangle states that the line joining the midpoints of the two adjacent sides is equal to half of the third side.
So,
JK = 2NO
2x + 12 = 24
x = 16 / 2
x = 8
Thus, the required simplified value of x is 8, for the given triangle.

Step-by-step explanation:
Sense 2 hours has passed you divide the amount of distance the plane has traveled by the amount of time it took. :)
Answer:
600 mph
Step-by-step explanation:
its the speed of the plane
the solution is distance travel which is 1,200 miles divided by the time 2 hours will be equal to 600 miles per hour (mph).
How do you do these questions?
Step-by-step explanation:
(a) Fₙ₋₁ > 0, so Fₙ₊₁ > Fₙ. Each term is bigger than the one before it, so the function is increasing, meaning the series will diverge to infinity.
(b) Fₙ₊₁ / Fₙ = (Fₙ + Fₙ₋₁) / Fₙ
Divide.
Fₙ₊₁ / Fₙ = 1 + (Fₙ₋₁ / Fₙ)
Rewrite the second fraction using negative exponent.
Fₙ₊₁ / Fₙ = 1 + (Fₙ / Fₙ₋₁)⁻¹
Take the limit of both sides as n approaches infinity.
lim(n→∞) Fₙ₊₁ / Fₙ = 1 + lim(n→∞) (Fₙ / Fₙ₋₁)⁻¹
Substitute with φ.
φ = 1 + φ⁻¹
Solve.
φ² = φ + 1
φ² − φ − 1 = 0
φ = [ -(-1) ± √((-1)² − 4(1)(-1)) ] / 2(1)
φ = (1 ± √5) / 2
Since the ratio can't be negative:
φ = (1 + √5) / 2

b=
what is the new equation written in slope-intercept form y=mx+b
Answer:
m= -2
b= 2
y= -2x + 2
Step-by-step explanation:
Just did it
The slope of a line is m = -2 that passes through the points (-3, 8) and (4.-6), the y-intercept (b) of the line is 2, and the equation is y = -2x + 2.
What is the slope of the line?The slope of a line is defined as the gradient of the line. It is denoted by m
Slope m = (y₂ - y₁)/(x₂ -x₁ )
Given that the line that passes through the points (-3, 8) and (4.-6).
Let
x₁ = -3, y₁ = 8
x₂ = 4, y₂ = -6
∵ Slope m = (y₂ - y₁)/(x₂ -x₁ )
Substitute values in the formula
m = (-6 - 8)/(4 -(-3))
m = (-14)/7
m = -2
y - 8 = m(x - (-3))
y - 8 = -2(x + 3)
y = -2x -6 + 8
y = -2x + 2
Since the slope-intercept form, y = mx+b
So the y-intercept (b) of the line,
b = 2
Thus, the slope of a line is m = -2 that passes through the points (-3, 8) and (4.-6), the y-intercept (b) of the line is 2, and the equation is y = -2x + 2.
