Answer:

m = 7.25

Step-by-step explanation:

8m + 7 - 5 = 60

Evaluate like terms.

8m + 2 = 60

Isolate 8m.

8m = 60 - 2

Evaluate.

8m = 58

Find m.

m = 58 ÷ 8

m = 7.25

Answer:

Step-by-step explanation:

l8m+7l = 65

(8m+7) = 65     or    -(8m+7) = 65

8m = 65-7   or      -8m = 65 + 7

m= 58/8    or       m = 72/(-8)

m= 7. 25 or      m = -9

Answer: for b: function one has a greater rate of change

Step-by-step explanation: sorry i don't know the first one

Answer:

a) -2 and 4, b) function 2

Step-by-step explanation:

Rate of change is the same thing as slope. For the first function, the table, we can use two of the points and the slope formula. I'll use (-1,3) and (-2,5). Remember the slope formula:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Plug the points in:

[tex]m=\frac{5-3}{-2-(-1)}\\m=\frac{2}{-1}\\m=-2[/tex]

(Remember that subtracting a negative = adding. I look at it like the two 'minus' signs form one plus sign, if that helps)

So the slope of function 1 is -2.

We can do the same thing with the second function. Two points that I notice on the graph are (-1,0) and (0,4). Let's use the same slope formula.

[tex]m=\frac{4-0}{0-(-1)}\\m=\frac{4}{1}\\m=4[/tex]

And the slope of function 2 is 4. That answers the first part. The second part asks about rate of change.

Function 2 has a greater rate of change, since 4>-2.

Hope this helps!

Answer: the first one.

Step-by-step explanation:

Answer:

"Team C scored 130 points."

Step-by-step explanation:

Let x represent how many points team B scored.

Team A: 3x + 6

Team B: x

Team C: x + 45

Total: 476 points

476 = (x) + (3x + 6) + (x + 45)

476 = x + 3x + 6 + x + 45

476 = 5x + 51

425 = 5x

x = 85

Team A:

3(85) + 6

= 261 pts

Team B:

= 85 pts

Team C:

(85) + 45

= 130 points

Answer:

Team c 130

Step-by-step explanation:

Answer:

1: Converse: If GH is 3, then G is at 4

Inverse: If G is not at 4, the GH is not 3

Contrapositive: If GH is not 3, then G is not 4

2: Converse: If QR =(~) RS, then R is the midpoint of QS

Inverse: If QR does not =(~) RS, then R is not the midpoint of QS

Contrapositive: If R is not the midpoint of QS, the QR does not =(~) RS.

Step-by-step explanation:

Converse is to switch the two

Inverse is to make them both untrue, like if 1 +1 is 2, then 2+2 is 4, you could say if 1+1 is not 2, the 2+2 is not 4

Contrapositive is to switch them around and make them both untrue

Based on the calculations using the given x-intercept of this graph, the value of a is equal to 11.

A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.

In Mathematics, the y-intercept of any graph (parabola) occurs at the point where the value of "x" is equal to zero (0). Similarly, the x-intercept refers to the point at which the graph of a function crosses the x-axis and the value of "y" is equal to zero (0).

Given that the x-intercept is at (a, 0), we would simply substitute the given points as follows:

y = (x − 4)^2 − 49

0 = (a − 4)^2 − 49

(a − 4)^2 = 49

Taking the square of both sides, we have:

a - 4 = √49

a - 4 = 7

a = 7 + 4

a = 11.

Answer:

10/11

Step-by-step explanation:

(8/11)/(4/5)

= (8/11) x (5/4)

= 40/44

= 10/11

Answer: 10/11

Step-by-step explanation: multiply by the reciprocal of the divisor (8/11*5/4). you can reduce the fraction, so we can make it 2/11*5/1. just multiply, and you have your answer.

Explanation:

Both points have the same x coordinate x = 0, so this is the equation of the vertical line. It cannot be written in y = mx+b form because the slope m is undefined.

Answer:

k = 10

Step-by-step explanation:

For f(x) = x³ + kx² - kx - 93 to be divisible by (x+3) with no remainder, it means that at (x + 3) is a factor of the polynomial f(x).

Thus, it means that at x = -3, f(x) must be equal to zero.

Thus;

(-3)³ + k(-3)² - k(-3) - 93 = 0

-27 + 9k + 3k - 93 = 0

12k - 120 = 0

12k = 120

k = 120/12

k = 10

Answer:

26/9

Step-by-step explanation:

whenever you divide fractions, they turn into a multiplication problem and use the second fraction's reciprocal. so it would look something like this:

13/2 * 4/9

just do straight multiplication

numerators: 13*4 = 52

denominators: 2*9 = 18

52/18 = 26/9

Answer:

20% 0f $65.00 is $13

$13 - $5= $8

Step-by-step explanation:

Percentage solution with steps:

Step 1: Our output value is 65.00.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$65.00=100\%$.

Step 4: Similarly, $x=20\%$.

Step 5: This results in a pair of simple equations:

$65.00=100\%(1)$.

$x=20\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both

equations have the same unit (%); we have

$\frac{65.00}{x}=\frac{100\%}{20\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{65.00}=\frac{20}{100}$

$\Rightarrow x=13$

Therefore, $20\%$ of $65.00$ is $13$

71 cookies were sold at $2.00 each, whereas 35 cookies were sold at $3.00

What are simultaneous equations?

Simultaneous equations are related equations that are solved together to determine their unknown variables

Given : bags of cookies sold for $2.00, $2.50, or $3.00, depending on the size. altogether, 106 cookies were sold, and $256 was earned for the sales.

Let X be number of cookies sold at $3.00

Then  cookies sold at $2.00 would be 2X

2X+X=106

3X=106

X=106/3

X=35(cookies sold at $3.00)

cookies sold at $2.00=106-35

cookies sold at $2.00=71
