Step 1:
Multiply the numbers in parentheses:
(-3 * 2) - (7 * (- 3)) - 10
-6 - (- 21) -10
Step 2:
Equal signs are added:
-6 + 21-10
Step 3:
Make the algebraic sum:
-6 + 21-10 = 5
Answer:
the final result is 5.

Answer:

$(-3)(2) - 7 ( -3) -10\\= (-6) - (-21) -10\\= -16 + 21 - 10\\= -5\\$

Step-by-step explanation:

We will follow the rule of BODMAS

B - Bracket Of

D - Division

M = Multiplication

A = Addition

S = Subtraction

On solving the give equation as per the order of BODMAS, we get -

$(-3)(2) - 7 ( -3) -10\\= (-6) - (-21) -10\\= -16 + 21 - 10\\= -5\\$

A player chooses one of the numbers 1 through 4. After the choice has been made, two regular four-sided (tetrahedral) dice are r

d1i1m1o1n [39]

Answer: $=\frac{-1}{16}$

Step-by-step explanation:

given data:

number to be chosen from = 1,2,3,4.

<u><em>Solution:</em></u>

ways the number can show

$2*3*1=6$ ways for your number to appear once.

$1*1=1$ ways for your number to appear twice.

$3*3=9$ ways for your number not to appear at all

$= \frac{6(1) + 1(2) - 9(1)}{16}$

$= \frac{6+2-9}{16}$

$=\frac{-1}{16}$

expected return of the player is $=\frac{-1}{16}$

Nichior compared the slope of the function graphed to the slope of the linear function that has an x-intercept of 2/3 and a y-in

marusya05 [52]

Answer:

The slope of f(x) is 1.5

Step-by-step explanation:

step 1

Find the slope of the linear function that has an x-intercept of 2/3 and a y-intercept of -1

so

we have the points

(2/3,0) and (0,-1)

The formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

substitute the values

$m=\frac{-1-0}{0-2/3}$

$m=\frac{-1}{-2/3}$

$m=\frac{3}{2}=1.5$

step 2

Find the slope of the function graphed

take the points

(0,-1) and (3,6) approximately

substitute in the formula

$m=\frac{6+1}{3-0}$

$m=\frac{7}{3}=2.33$

step 3

we know that

f(x) represents the function with the smaller slope

The smaller slope is 1.5

therefore

The slope of f(x) is 1.5

Demonstrate two different ways to solve the equation 5^(2x+1) = 25.

Tanzania [10]

Answer:

Step-by-step explanation:

Method 1: Taking the log of both sides...

So take the log of both sides...

5^(2x + 1) = 25

log 5^(2x + 1) = log 25 <-- use property: log (a^x) = x log a...

(2x + 1)log 5 = log 25 <-- distribute log 5 inside the brackets...

(2x)log 5 + log 5 = log 25 <-- subtract log 5 both sides of the equation...

(2x)log 5 + log 5 - log 5 = log 25 - log 5

(2x)log 5 = log (25/5) <-- use property: log a - log b = log (a/b)

(2x)log 5 = log 5 <-- divide both sides by log 5

(2x)log 5 / log 5 = log 5 / log 5 <--- this equals 1..

2x = 1

x=1/2

Method 2

5^(2x+1)=5^2

2x+1=2

2x=1

x=1/2
