d=(9−(−2))2+(3−3)2−−−−−−−−−−−−−−−−−−√  

d=(11)2+(0)2−−−−−−−−−−√

d=121+0−−−−−−√

d=1–√21

d=11

Answer: C $34.50

Step-by-step explanation: The 15% of 230 is 34.50, so the digital camera was $34.50 off.

Step-by-step explanation:

12x - 6         3x+3       6(2x-1)

1  = 6           1 = 6          1 = 6

2  = 18         2 = 9         2 = 18

3 = 30         3 = 12        3 = 30

The equivalent expressions are 12x-6 and 6(2x-1)

Answer: Am thinking (0,10)

Step-by-step explanation:

Answer:0,10, 10,0.

Step-by-step explanation:

The equation is in point-slope form, y − y1 = m(x − x1), where the slope, m, is -1, and the line goes through the point (4,6).

Use the slope to find a second point on the line. So, from the point (4,6), go down 1 unit and to the right 1 unit. Therefore, the line also goes through the point (3,5).

This is the graph showing a line that goes through (4,6) and (3,5).

Answer:

6√2

Step-by-step explanation:

According to the question

The equation is

Sin(45°)=6/x

√2/2=6/x

√2x=12

x=12/√2

x=12×√2/√2²

x=12×√2/2

x=6√2

Answer:

The graph shows the solution of the inequality y > [tex]\frac{4}{3}[/tex] x - 2 ⇒ D

Step-by-step explanation:

In the inequality,

From the given graph

∵ The slope of the line = [tex]\frac{2--6}{3--3}[/tex] = [tex]\frac{2+6}{3+3}[/tex] = [tex]\frac{8}{6}[/tex] = [tex]\frac{4}{3}[/tex]

∵ The y-intercept is (0, -2)

∵ The line is dashed and the shaded area is over the line

→ By using the 2nd and 3rd notes above, the line is dashed and

   the sign of inequality is >

∴ The inequality is y > [tex]\frac{4}{3}[/tex] x - 2

∴ The graph shows the solution of the inequality y > [tex]\frac{4}{3}[/tex] x - 2

Step-by-step explanation:

Answer: b. The slope indicates that the percent is falling at about 0.4% each year. The y-intercept indicates the percent in 1985 should have been about 19%

Step-by-step explanation:

The slope of straight line indicates the rate of change and in a regression equation is the m in: y = mx + c

In the regression equation of y = -0.42 + 19.26, the slope is -0.42 indicating that the rate of change has been -0.42% which means that the percent is falling at about 0.42% per year.

The y intercept (c) measures the rate at the origin and in this equation is 19.26. As the origin of the line is 1985, this means that the percent in 1985 should have been about 19%.

Answer:

B. y = x - 8

Step-by-step explanation:

✔️First, find the slope of the line using two points on the line, say (0, -8) and (8, 0):

[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} = \frac{0 - (-8)}{8 - 0} = \frac{8}{8} = 1 [/tex]

slope (m) = 1

✔️Find the y-intercept (b):

The y-intercept is -8. The line intercepts the y-axis at y = -8.

b = -8

✔️Next, substitute m = 1, and b = -8 into y = mx + b:

Thus:

y = (1)x + (-8)

y = x - 8

B. (2d^2 - 3d-21)/((d+2)(d+3))

Step-by-step explanation:

(d^2 - 5d + 6)/(d^2 + d - d) + (d^2 - 4d-5)/(d^2+3d+2)

(d^2 - 5d + 6)/(d^2 + d - d) = (d-3)/(d+3)

(d^2 - 4d-5)/(d^2+3d+2) = (d - 5)/(d+2)

(d-3)/(d+3) + (d - 5)/(d+2)

Least common Multiplier of d + 3 and d + 2 is (d+3)(d+2)

((d-3)(d+2))/((d+3)(d+2)) + ((d-5)(d+3))/((d+2)(d+3))

((d-3)(d+2)+(d-5)(d+3))/((d+3)(d+2))

Answer:

3 - x

Step-by-step explanation:

f(x) = -x + 6

f(x + 3)

Substitute (x + 3) in for x;

f(x + 3) = -(x + 3) + 6

= - x - 3 + 6

= -x + 3

Answer:

35 miles/hour

Step-by-step explanation:

Divide any number of miles by the corresponding number of hours above.

70 miles / 2 hour = 35 miles/hour

Answer: 35 miles/hour

Answer:

44 mph

Step-by-step explanation:

Given that:

Before lunch :

Time taken = 2hrs ; at speed = x mph

After lunch :

Time taken = 3hrs ; at speed = x + 10 mph

Total distance covered = 250 miles :

Distance = speed * time

(2 * x) + (3 * (x + 10)) = 250

2x + 3x + 30 = 250

5x + 30 = 250

5x = 250 - 30

5x = 220

x = 220/ 5

x = 44 mph

Rate before lunch is 44mph

Answer:

Step-by-step explanation:

Given trinomial

Let's try to factor 4t² - 9t + 2

First find it's zeros:

So yes, it is factorable:

The given trinomial factored:

Answer:  Yes, this trinomial -4(4t² -9t + 2) is factorable.

It is   h =(-4)(4t -1 )(t -2) converted from the explanation

[tex]y\ =\left(-4\right)\left(4x\ -1\right)\left(x\ -2\right)[/tex]

A graph of the equation is in the attachment. There are two equations, but only one graphed parabola because they are identical.

Step-by-step explanation: I am using x in place of t in this explanation, and leaving out the factored (-4) to simplify.

Using the systematic new AC Method to factor trinomials (Socratic Search)  Starting with a quadratic equation in the form

y = ax² + bx + c  

This involves converting  the equation by multiplying the leading coefficient, a, times the constant, c

y =4x² –9x + 2

=4(x + p)(x + q)

Converted trinomial:

y' = x² –9x + 8

= (x + p')(x + q').

Here p' and q' will have the same – signs because the b term is negative and the c term is positive.

Factor pairs of ac = 8 are -1 and –8. This sum is –9 = b. Then p' = -1 and q' = -8.

Then divide the second factor by the original coefficient, 4.

Replacing the original leading factor (-4) the factored equation looks like

y = -4(4x - 1)(x - 2)

To solve for x

p =p’/a  = ¼   or 4x - 1 = 0  4x = 1   x = ¹/₄

and

q ='q/a

= 8/4 = 2    OR  x -2 = 0  x = 2

The second attachment shows some other ways to set up the equation without the (-4) to solve, and then replace that factor. You get the same values for x.

I hope this helps and is not too confusing. There may be other ways to factor this equation.
