Answer:

2 is the slope

Step-by-step explanation:

the equation is y=mx+b so if it is

y= 2x+7 that means the slope is 2

Answer:

2

Step-by-step explanation:

This equation is in y=mx+b form.

Slope = m

Y-intercept = b

This will give you the slope of 2 :)

Final Answer: [tex]s = -\frac{3}{2}[/tex]

Steps/Reasons/Explanation:

Question: Equations with variables on both sides: decimals and fractions, algebra 2. [tex]0.5s + 1 = 7 + 4.5s[/tex].

Step 1: Subtract [tex]0.5[/tex] from both sides.

[tex]1 = 7 + 4.5s - 0.5s[/tex]

Step 2: Simplify [tex]7 + 4.5s - 0.5s[/tex] to [tex]7 + 4s[/tex].

[tex]1 = 7 + 4s[/tex]

Step 3: Subtract [tex]7[/tex] from both sides.

[tex]1 - 7 = 4s[/tex]

Step 4: Simplify [tex]1 - 7[/tex] to [tex]-6[/tex].

[tex]-6 = 4s[/tex]

Step 5: Divide both sides by [tex]4[/tex].

[tex]-\frac{6}{4} = s[/tex]

Step 6: Simplify [tex]\frac{6}{4}[/tex] to [tex]\frac{3}{2}[/tex].

[tex]-\frac{3}{2} = s[/tex]

Step 7: Switch sides.

[tex]s = -\frac{3}{2}[/tex]

Answer:

13 1/3 cups

Step-by-step explanation:

The ratio of flour to dozens of cookies is 4:3 or 1 1/3:1

1 1/3 x 10 = 13 1/3

Answer:

13 1/3

Step-by-step explanation:

12 cups cover the first 9 cookies and than just divide 4 by 3 and you will get 1.3 which is 1 1/3 of a cup

Part (a)

Use the slope formula to compute the slope from x = 4 to x = 6

So effectively we're finding the slope of the line through (4,70) and (6,68)

We get the following

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

m = (68-70)/(6-4)

m = -2/2

m = -1

Repeat for the points that correspond to x = 6 and x = 8

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

m = (73-68)/(8-6)

m = 5/2

m = 2.5

Now average the two slope values

We'll add up the results and divide by 2

(-1+2.5)/2 = 1.5/2 = 0.75

The estimate of T'(6) is 0.75

This works because T'(x) measures the slope of the tangent line on the T(x) curve. Averaging the secant slopes near x = 6 will help give us an estimate of T'(6), which is the slope of the tangent at x = 6 on T(x).

==============================================

Part (b)

The value T'(6) = 0.75 represents the instantaneous rate of change of the temperature per hour.

More specifically, T'(6) = 0.75 means the temperature is increasing by an estimated 0.75 degrees per hour at the exact instant of x = 6 hours. This instantaneous rate of change is like a snapshot at this very moment in time; in contrast, the slope formula results we computed above measure the average rate of change between the endpoints mentioned.

Answer:

First question is D, (2/3)x+7

Second is A, m = (-1/3)

Step-by-step explanation:

parallel lines have the same slope. m=slope.

perpendicular lines are opposite sign reciprocals. slope is 3, perpindicular slope is (-1/3)

Step-by-step explanation:

Let us intepret this condition in our context:

"...that the minimum value is not less than 2 and the maximum value is not greater than 5"

This means that when we roll the dice, we do not want 1 or 6 to appear. Instead we wish for 2/3/4/5 to appear.

The probability of getting these four sides out of six in a roll is 4/6, or 2/3.

We have to roll this dice 4 times. Hence we raise the probability to a power of 4:

Total probability = (2/3)⁴

= (2)⁴ / (3)⁴

= 16/81. (C)

Answer:  k [tex]\leq[/tex] -11

Step-by-step explanation:

8 + k [tex]\leq[/tex]  -3  Subtract 8 from both sides

-8            -8

   k [tex]\leq[/tex] -11

The solution to the given inequality 8 + k ≤ -3 is k ≤ -11 which represents all values of k that are less than or equal to -11.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The given inequality is given in the question:

8 + k ≤ -3

To solve the inequality 8 + k ≤ -3, you can start by subtracting 8 from both sides to isolate the variable:

k ≤ -3 - 8

k ≤ -11

The solution to this inequality is all values of k that are less than or equal to -11. This includes all negative numbers less than or equal to -11, as well as -11 itself.

Therefore, the solution to the given inequality is k ≤ -11.

Answer:

The correct option is;

A. Car B was 10 miles east of car A

Step-by-step explanation:

The given parameters are;

The speed of car A = 45 miles per hour

The direction of car A = East

The distance of car B from Johnstown after 2 hours = 100 miles east

The direction of Car B = East

The distance of car B from Johnstown is given on the graph

Therefore, the initial distance of car A from Johnstown when car A began driving is given as follows;

The initial distance, east, of car A from Johnstown = 100 - 2 × 45 = 10

∴ The initial distance, east, of car A from Johnstown = 10 miles

From the graph, the initial distance, east, of car B from Johnstown = 20 miles

Therefore, car B was 10 miles east of car A

Answer:

Car B was 10 miles east of car A

Step-by-step explanation:

He walked 25 already. So you have x=25. He walks 5 km during each trip. There are 12 trips. 5 times 12 is 60. x=25+60. So, 25 plus 60 is 85.

Answer:

3 is the correct answer

Step-by-step explanation:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

              8*x-6-(12+2*x)>0

            6x - 18  =   6 • (x - 3)

The value of the inequality is x > 3 , which is 5

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the inequality equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

8x - 6 > 12 + 2x

Subtracting 2x on both sides , we get

6x - 6 > 12

Adding 6 on both sides , we get

6x > 18

Divide by 3 on both sides , we get

x > 3

So , the value of x is numbers greater than 3

Hence , the inequality is x > 3

Answer: Choice E) Insufficient information to prove congruence.

============================================================

Explanation:

We're given that AB = DC and BE = CE. This means we have two pairs of congruent sides and we could use SAS if we know that angle ABE = angle DCE. However, we don't know this information.

While we do know that angle AEB = angle DEC (vertical angle theorem), this is not enough information. Recall that SSA is not a valid congruence theorem. The angles in question are not between the sides mentioned in the previous paragraph.

Therefore, we don't have enough information to prove the triangles congruent.
