The unit rate is x:1, like 60 miles to 1 hour, or 60/1. To find the answer, put the number of textbooks over the number of students and then simplify the fractions- you will see that they all boil down to 5/1, or 5 textbooks per 1 student.

Answer:

Equation: y = x - 1

Step-by-step explanation:

Given: y = x - 6

Slope-Intercept Form: y = mx + b -

where:

Note: parallel lines have the same slope

1. Determine the slope and y-intercept of the given equation:

⇒ y = x - 6 has a slope of 1, and a y-intercept of -6

2. Find the equation of the line parallel line that passes through the point (-5,-6):

⇒ y = x + b [substitute -5 for x and -6 for y]

⇒ -6 = -5 + b [add 5 to both sides]

⇒ -6 + 5 = -5 + 5 + b

⇒ -1 = b

Equation: y = x - 1

3. Check your answer using point (-5, -6):

⇒ y = x - 1

⇒ -6 = -5 - 1

⇒ -6 = -6 ✔

This statement is correct

Therefore, the equation of the line is y = x - 1

Answer:

1

Step-by-step explanation:

The formula for slope is y2 - y1 over x2 - x1.

-8--2 = -6

6-12= -6

-6/-6 = 1

Step-by-step explanation:

Join C to B to form BC, thereby creating ∆ ABC

OC is the radius of the circle (O is the center of the circle).

AD is the tangent to the circle at point C

When a radius of a circle meets with a tangent of the same circle, the angle between them is 90°

<ACB = <ACO = 90°

<ABC = 180 - (<ACB + <BAC)

= 180-(90+40)

= 50

Look closely,

<ABC = x = 50°

.

.

Do same as Example 7

Join O to B to form OB, which is the radius of the circle.

<ABO= 90°

< BOA = 50°

<OAB= x+25= 180-(90+50)

x+25= 40°

x = 15°

The average change in distance for each increase of 1 in the iron number is -10, and the y-intercept of the graphs are not the same

From the graph, we have the following points:

(x,y) = (4, 145) and (3,155)

The average change in distance is calculated using:

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

So, we have:

[tex]m = \frac{155 - 145}{3 - 4}[/tex]

Evaluate

m = -10

Hence, the average change in distance for each increase of 1 in the iron number is -10

The rate, -10 in (a) means that:

The distance decreases by 10 yards for each number of iron

The y-intercept is the point where the graph crosses the y-axis

From the attached graphs, we have:

Hence, the y-intercept of the graphs are not the same

Step-by-step explanation:

75/15=5 which means he makes $5 per hour

5*32=160

Answer:

Step-by-step explanation:

To solve for t, you have to isolate it on one side of the equation.

First, you have to switch sides.

→ -9+4t=-17

Add by 9 from both sides.

[tex]\Longrightarrow: \sf{-9+4t+9=-17+9}[/tex]

Then, you solve it.

-17+9=-8

4t=-8

Divide by 4 from both sides.

[tex]\sf{\dfrac{4t}{4}=\dfrac{-8}{4}}[/tex]

Solve.

Divide the numbers from left to right.

-8/4=-2

[tex]\Longrightarrow: \boxed{\sf{t=-2}}[/tex]

I hope this helps. Let me know if you have any questions.

Answer:

[tex]t = -2[/tex]

Step-by-step explanation:

Step 1:  Add 9 to both sides

[tex]-17 = -9 + 4t[/tex]

[tex]-17 + 9 = 4t - 9 + 9[/tex]

[tex]-8 = 4t[/tex]

Step 2:  Divide both sides by 4

[tex]\frac{-8}{4} = \frac{4t}{4}[/tex]

[tex]-2 = t[/tex]

Step-by-step explanation:

well, one way to look at it is that ∠4 + ∠5 = 180

we are GIVEN the info that ∠4 = 40

therefore 180 - 40 - ∠5

Answer:

30 cm

Step-by-step explanation:

So what we are given here is a case of similar figures.

When we are given similar figures, the ratio of the width of both figures should be similar to the ratio of the length of both figures.

I'll demonstrate it in the following problem.

We know one rectangle has a length of 18 cm and a width of 6cm.

The other rectangle has a width of 10 cm.

Let's take a ratio of the width of both rectangles.

We take the width of 6 cm for the first rectangle to the width of 10 cm for the second rectangle.

w1 = 6 cm

w2 = 10 cm

6 cm : 10 cm = 3 : 5

The ratio given is 3 : 5. Let's use these ratios to find lengths.

l1 = 18 cm

l2 = x cm

3 : 5 = 18 : x

To find x, we just solve this like an equation, where we let ratios be division signs.

3/5 = 18/x

Multiply both sides by 5x

3x = 90

Divide both sides by 3

x = 30 cm

The length of the missing side is 30 cm. We found the answer to the length by using the ratios obtained from the widths.

Answer:

I don't see the equation for the line, but I describe the process.

Step-by-step explanation:

Let's look for a line that has the form y=mx+b, where m is the slope and b the y-intercept (the value of y when x=0).

The slope of a perpendicular line is the negative inverse of the slope of the reference line.  In this case the equation for the reference line is missing.  If it is in the form y=mx+b, take the m value, invert it, and then give it a "-" sign.  For example, if the line is y = 2x +1, the negative inverse of the slope of 2 would be -(1/2).

The new line will have this new slope [-(1/m)] to make it y = -(1/m)x + b.

To find b, use the given point of (3,-2) in the equation and solve for b:

y = -(1/m)x + b

-2 = -(1/m)*(3) + b

Then solve for b and you'll have the equation for the solution to the problem.
