Write this expression in standard form ... 3(-2a - 5)

Answer:

S=1.25

Step-by-step explanation:

If this is confusing pls let me know!! :) (p.s. sorry bout my handwriting lol)

A simple run down of the problem I guess is that first you need to solve one equation for either s or b. I chose the first equation to solve for b and I got b=(-3/2s)+(9.25/2). Then, the second thing you need to do is to put the answer to b in the second equation. This would be 3((-3/2s)+(9.25/2))+45 = 13.25. Then you basically solve that equation for s and you should get s=1.25. If you need to also find b you can plug s=1.25 into either of the starting equations. All done :) sorry this took long lol

Ans: The answer of your question is S=1.25

Answer:

x=2 or x=−2

Step-by-step explanation:

Let's solve your equation step-by-step.

x2−4=0

Step 1: Add 4 to both sides.

x2−4+4=0+4

x2=4

Step 2: Take square root.

x=±√4

x=2 or x=−2

Answer:

9cm

Step-by-step explanation:

s + s + 8 + 12 = 38

(s + s) + (8 + 12) = 38

2s + 20 = 38.

so, we have to subtract 20 from both sides, so it will be 2s = 18.

2s/2 = 18/2. so that means, s = 9.

hope this will help you!

i have a simple hack for this

Step-by-step explanation:

fyou see how theres a line? yes so act as if the 2 parts arent together just do 8x5x22 which equals 880 then do 8x5x12 which equals 480 then we add them together because the shapes were originally together so we do 880+480 which gets us to 1360

Answer:

Answer:22

Step-by-step explanation:

Answer:

x=22

Step-by-step explanation:

add 38 to both sides

you'll have 3x=66 after adding

then divide both sides by three so have x by itself and you'll get

x=22

Answer: x=7

Step-by-step explanation:

Step 1: Subtract 17x from both sides.

13x+15−17x=17x−13−17x

−4x+15=−13

Step 2: Subtract 15 from both sides.

−4x+15−15=−13−15

−4x=−28

Step 3: Divide both sides by -4.

−4x/−4 =−28/−4

x=7

Answer:

3√512 = 8

Step-by-step explanation:

Step 1: Find the prime factors of 512

512 = 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2 × 2

Step 2: Pair the factors of 512 in a group of three, such that they form cubes.

512 = (2 × 2 × 2) × (2 × 2 × 2) × (2 × 2 × 2)

512 = 23 × 23 × 23

Using the law of exponent, we get;

512 = 29 [am.an = (a)m+n]

Or

512 = (23)3 [(am)n = amn]

512 = 83

Step 3: Now, we will apply cube root on both the sides to take out the factor (in cubes) as a single term.

3√512 = 3√(83)

So, here the cube root is eliminated by the cube of 8.

Hence, 3√512 = 8

Answer:

Probability of spinning a odd number is 5/9

I don't know about flipping head

Probability of spinning a 3 is 1/9

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

Explanation:

The sample space of the spinner is {1,2,3,4,5,6,7,8,9} which represents all the possible outcomes. We can only pick one of those values. Of that list, the subset {1,3,5,7,9} represents all the odd numbers. This is the event space because we want to land on an odd number.

There are 5 items in the event space and 9 items in the sample space. The probability of getting an odd number is 5/9.

The probability of flipping heads is 1/2 since we have one side we want (heads) out of two sides total.

Lastly, the probability of landing on a '3' is 1/9 because there's only one '3' out of 9 values total.

---------

We'll multiply those fractions to get the final answer. This works because each event is independent of one another.

(5/9)*(1/2)*(1/9) = (5*1*1)/(9*2*9) = 5/162

Now use your calculator to find that: 5/162 = 0.030864 approximately which rounds to 0.0 or just 0 when rounding to the nearest tenth.

Unfortunately this is one case where rounding will creates a misleading result. The true probability isn't 0 because the events described are possible. The probability is just really small.

Answer:

No, she is wrong. Look at the coordinates on function A. They don't match up.

Answer:

50+12x≥158

Step-by-step explanation:

starting with $50, adding $12 for every car washed (x), must be at least, but can be greater than, $158.

The required inequality for Silvio to earn more than $158 in one day is, $50 + 12x ≥ 158.

Given that,
Silvio works at a car wash. He earns $50 per day and $12 per car washed. Silvio wants to earn at least $158 in 1 day.
To determine the inequality represents the number of cars (C) Silvio must wash to reach his goal.

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,
Let the number of cars washed by Silvio be x,
According to the question,
Silvio works at a car wash. He earns $50 per day and $12 per car washed.
Total earning of the day = $50 + 12x
Silvio wants to earn at least $158 in 1 day. So, his total earnings of the day must be greater equal to $158.
$50 + 12x ≥ 158.

Thus, the required inequality for Silvio to earn more than $158 in one day is, $50 + 12x ≥ 158.

Answer:

Step-by-step explanation:

Let the equation is, y = x² + bx + c

Here, b = Sum of the roots

And c = multiplication of the roots

Roots of the equation are (5 + 2i) and (5 - 2i).

Step 1,

Sum of the roots 'b' = (5 + 2i) + 95 - 2i)

                             b = 10

Step 2,

Multiplication of the given roots = (5 - 2i)(5 + 2i)

                                                     = 5² - (2i)²

                                                     = 25 + 4

                                                     = 29

Step 3

Therefore, equation of the quadratic function will be,

y = x² + 10x + 29
