Find the slope of the line using the graph. Write an equation of the line using the graph.
Answer:
slope: -3equation: y = -3x +5Step-by-step explanation:
The slope formula can be used with the marked points.
m = (y2 -y1)/(x2 -x1)
m = (-1 -2)/(2 -1) = -3/1 = -3
The graph apparently intersects the y-axis at y=5, so the slope-intercept equation is ...
y = mx +b . . . . . . . line with slope m and y-intercept b
y = -3x +5

Drag all of the steps necessary into the box to find the product of 2.3 x 0.5 using partial products.
\left[\begin{array}{ccc}1&2&3\\4&5&6\\7&8&9\end{array}\right]
The product of 2.3 x 0.5 using partial products is 1.15.
What is a partial products?A product obtained by multiplying a multiplicand by one digit of a multiplier having more than one digit.(So, the 2 in 23 would actually be 20.) For instance, 23 x 42 would become (20 x 40) + (20 x 2) + (3 x 40) + (3 x 2).
Given:
The given integer is
2.3 x 0.5
=23x5/100
According to given question we have
By use of partial products we get,
The partial product method involves multiplying each digit of a number in turn with each digit of another where each digit maintains its place.
(20*00)+(20*5)+(3*00)+(3*5)
=0+100+0+15
=115
=115/100
=1.15
Therefore, the product of 2.3 x 0.5 using partial products is 1.15.

A plane flies 15 miles in 20 seconds. How long would it take the plane to cover 30 miles?
Answer:it would take the plane 40 seconds
Step-by-step explanation:
if you multiply by two then you would be able to get 30
like 15 times 2 and since it’s 15 miles to 20 seconds or 15:20 you would have to multiply by the same number.

Step-by-step explanation:
2x+3
Answer:
8*9=72, I think and if is wrong i'm sorry
Step-by-step explanation:
x = first number
x + 1 = second number
1 / x + 1 / ( x + 1 ) = 17 / 72
[ 1 * ( x + 1 ) + 1 * x ] / [ x * ( x + 1 ) ] = 17 / 72
[ ( x + 1 ) + x ] / [ x * x + x * 1 ) ] = 17 / 72
( 2 x + 1 ) / ( x ^ 2 + x ) = 17 / 72 Multiply both sides by 72
72 * ( 2 x + 1 ) / ( x ^ 2 + x ) = 17
( 72 * 2 x + 72 * 1 ) / ( x ^ 2 + x ) = 17
( 144 x + 72 ) / ( x ^ 2 + x ) = 17 Multiply both sides by x ^ 2 + x
144 x + 72 = 17 * ( x ^ 2 + x )
144 x + 72 = 17 * x ^ 2 + 17 * x
144 x + 72 = 17 x ^ 2 + 17 x Subtract 144 x to both sides
144 x + 72 - 144 x = 17 x ^ 2 + 17 x - 144 x
72 = 17 x ^ 2 - 127 x Subtract 72 to both sides
72 - 72 = 17 x ^ 2 - 127 x - 72
0 = 17 x ^ 2 - 127 x - 72
17 x ^ 2 - 127 x - 72 = 0
The solutions are:
x = - 9 / 17 and x = 8
- 9 / 17 isn't positive integers so x = 8
first number = 8
second number = 8 + 1 = 9
Proof:
1 / x + 1 / ( x + 1 ) =
1 / 8 + 1 / 9 =
( 1 * 9 + 1 * 8 ) / ( 8 * 9 ) =
( 9 + 8 ) / 72 = 17 / 72

90 - 55 = 35
Divide 35 by the original temperature -
35/90 = 0.388
Multiply 0.388 by 100 to find the percent -
38.8%
Round to the nearest percent -

If 3sin ⁻¹ (2x/1+x²)-4cos⁻¹(1–x²/1+x²)+2tan⁻¹(2x/1–x²)=π/3. Then, x=.
a 1/√3 b1/√2 c 2 d 1
Answer:
Option A.)
The answer is 1/√3
Step-by-step explanation:
3sin⁻¹ (2x/1 + x²) - 4cos⁻¹ (1 - x²/1 + x²) + 2tan⁻¹ (2x/1 - x²) = π/3
Put x = tanθ
3sin⁻¹ (2tanθ/1 + tan2θ) - 4cos⁻¹ (1 - tan2θ/1 + tan2θ) + 2tan⁻¹ (2tanθ/1 - tan2θ) = π/3
3sin⁻¹ (sin2θ) - 4cos⁻¹ (cos2θ) + 2tan⁻¹ (tan2θ) = π/3
3.2θ - 4.2θ + 2.2θ = π/3
⇒ 2θ = π/3
⇒ θ = π/6
∴ tan-1x = π/6 ⇒ x = tan (π/6) = 1/√3
Thus, The answer is 1/√3
