Answer:

= 7/ 8

Step-by-step explanation:

We can find the slope using the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 10-3)/( -2 - -10)

    = ( 10-3)/( -2 +10)

    = 7/ 8

Answer:

Answer:

x=-3/2y+2

y= y=−3x+6

Step-by-step explanation:

solve for x.

2x+3y=4

Add -3y to both sides.

2x+3y+−3y=4+−3y

2x=−3y+4

Divide both sides by 2.

2x/2= -3+4/2

x= -3/2 y+2

solve for y.

y+3x=6

Add -3x to both sides.

3x+y+−3x=6+−3x

y=−3x+6

Answer:

It takes the word processor 117 minutes to word process and spell check 27 pages.

Step-by-step explanation:

With the information provided, you can use a rule of three to find how long it would take to word process and spell check 27 pages given that it takes 26 minutes to word process and spell check 6 pages:

6 pages   →  26 minutes

27 pages  →          x

x=(27*26)/6=117 minutes

According to this, the answer is that it takes the word processor 117 minutes to word process and spell check 27 pages.

In this case, we need to substitute n with 10.

So, it is like this: f(10) = 3(10) + 4

f(10) = 3(10) + 4

f(10) = 30 + 4

f(10) = 34

Answer:

x = 4

Step-by-step explanation:

1.5(x + 4) - 3 = 4.5(x - 2)

Distribute;

1.5x + 6 - 3 = 4.5x - 9

Collect like terms;

1.5x + 3 = 4.5x - 9

Subtract 1.5x from both sides;

3 = 3x - 9

Add 9 to both sides;

12 = 3x

Divide both sides by 3;

x = 4

[tex]\huge\boxed{t=3}[/tex]

Step-by-step explanation:

[tex]-5(t+3)=-30[/tex]

[tex]-5(t+3)=-30[/tex]    divide both sides by (-5)

[tex]\dfrac{-5\!\!\!\!\diagup(t+3)}{-5\!\!\!\!\diagup}=\dfrac{-30}{-5}[/tex]

[tex]t+3=6[/tex]       subtract 3 from both sides

[tex]t+3-3=6-3\\t=3[/tex]

[tex]-5(t+3)=-30[/tex]       use the distributive property a(b + c) = ab + ac

[tex](-5)(t)+(-5)(3)=-30[/tex]

[tex]-5t-15=-30[/tex]     add 15 to both sides

[tex]-5t-15+15=-30+15[/tex]

[tex]-5t=-15[/tex]         divide both sides by (-5)

[tex]\dfrac{-5t}{-5}=\dfrac{-15}{-5}\\\\t=3[/tex]

Answer:

A

Step-by-step explanation:

Ok first we need to find rate of MILES per HOUR

320/6.4=50

m= miles in 9 hours

9*50=450

is your answer

A

(6.4*9)/320m=Hours/miles

Hope this helps!

The number of miles the bus will travel in 9 hours will be 6.4 / 320 = 9 / m. Then the correct option is B.

A ratio is a collection of ordered integers a and b represented as a/b, with b never equaling zero. A proportionate expression is one in which two items are equal.

A bus travels 320 miles in 6.4 hours. if the bus continues at the same rate.

We know that speed is the ratio of distance and time. Then we have

The number of miles the bus will travel in 9 hours will be

320 / 6.4 = m / 9

6.4 / 320 = 9 / m

Then the correct option is B.

The statement supported the graph is

The axis of symmetry is x = 3

The coordinates of the y-intercept are (0,7)

A line that divides an object into two equal halves and produces a mirror-like reflection of each side of the object is known as an axis of symmetry.

1. The axis of symmetry is x = 3

The axis of symmetry is the central axis of the graph, which signifies the middle point of the graph. It is evident that this graph is centered on x = 3.

2. The coordinates of the y-intercept are (0,7)

The y intercept is the point where the graph meets the y-axis, that is, the value of y on the graph when x=0.

From the graph, the coordinates of the y-intercept is (0, 7)

3. The X-intercept is located at (-3,0)

The x intercept is the point where the graph meets the x-axis, that is, the value of x on the graph when y=0.

From the graph the curve x axis at x= 1.5 and x= 4.5

So, the x-intercept is truly located at (1.5, 0) and (4.5,0)
