How do I solve this please help me Im failing Algebra1
-2x+1<7

Answer:

Step-by-step explanation:

The vertex form of  the equation of the parabola with vertex (h, k)   is:

y = a(x - h)² + k  

So  the equation of the parabola with vertex (3, 4):

y = a(x - 3)² + 4

The parabola passes through point (2, -2) so if x=2 then y=-2

- 2 = a(2 - 3)² + 4

- 2 -4 = a(-1)² + 4 -4

- 6 = a

So, the equation written in vertex form of a parabola with a vertex of (5, 7) that passes through (2, -2):

                                       y = - 6(x - 3)² + 4  

Answer:

General Formulas and Concepts:

Pre-Alg

Step-by-step explanation:

Step 1: Define inequality

-3 - x - 27 > 85

Step 2: Solve for x

Here we see that any number x smaller than -115 would work as a solution.

Answer:

The area would be 168ft. The rectangle's area would be 144ft, and the triangle's area would be 24ft.

Rectangle:

18×8=144

Triangle:

8×3=24

Answer:

The area is 168

Step-by-step explanation:

Instead of trying to find the area of the trapezoid, you can easily figure out the area of the rectangle and triangle present in the picture.

first, multiply 18 by 8 to get the area of the rectangle. 18 x 8 = 144

Then, use the equation for area of triangle L x W/ 2 = A

(6 x 8)/2 = 24

add these 2 values.

24 + 144

168 is your final  answer

Answer:

1/-5 should be the answer

9514 1404 393

Answer:

  y = 1

Step-by-step explanation:

Recognize that 25 and 125 are powers of 5 and rewrite the equation in terms of powers of 5.

The applicable rules of exponents are ...

  (a^b)^c = a^(bc)

  (a^b)/(a^c) = a^(b-c)

  (a^b)(a^c) = a^(b+c)

__

Your equation can be written as ...

  [tex]25^4\div5^{5y}=125^y\\\\(5^2)^4\div5^{5y}=(5^3)^y\\\\5^{8-5y}=5^{3y}\\\\8-5y=3y\qquad\text{equate exponents of the same base}[/tex]

Now this can be solved as an ordinary linear equation.

  8 = 8y . . . . . . add 5y to both sides

  1 = y . . . . . . . divide by 8

The solution is y = 1.

Answer:

5 boys play all the two games

25 boys play only one game

Step-by-step explanation:

Sets

There are two sets defined in the question: one for the boys who play hockey (H) and the other for the boys who play volleyball (V).

All the boys play at least one of the two games, so no elements are outside both sets.

There are 30 boys in total. 20 of them play hockey and 15 play volleyball. Since the sum of both numbers is greater than the total of boys, the difference corresponds to the boys who play both games.

Thus 20 + 15 - 30 = 5 boys play both games

Given that 5 boys are shared by both sets, from the 20 playing hockey, 15 play ONLY hockey. From the 15 boys playing volleyball, 10 play ONLY volleyball.

Thus 15 + 10 = 25 boys play only one game.

The required solutions,
(A) Association of the given expression gives 3060.402.
(B) Conversion of the word form of number into digit form gives 1700.003.

Decimal value is defined as showing the place value of the digits in a decimal number. If any proportion of the digit is lower than 1 it would be represented after the dot right to the absolute value,

Here,
A. 3,000 + 60 + 0.4 +0.002
Simplify the above expression by the association of the numbers,
3,000 + 60 + 0.4 +0.002 = 3060.402

B. One hundred seventeen and three-thousandths
Convert words to numbers,
= 1700.003

Thus, the required solutions,
(A) Association of the given expression gives 3060.402.
(B) Conversion of the word form of number into digit form gives 1700.003.

Answer:

x=80

Step-by-step explanation:

Answer:

The equation is;

y = (-x-23)/25

Step-by-step explanation:

The equation of a straight line can be given as y = mx + b

where m is the slope and b is the y-intercept

for y = 25x + 4

m is 25

Now, we need the slope of a line perpendicular to this,

If two lines are perpendicular, the result of the product of their slopes is -1

m1 * m2 = -1

25 * m2 = -1

m2 = -1/25

Mathematically, we have the slope in the point slope form as ;

y+3 = -1/25 (x - 2)

y = -x/25 + 2/25

y = -x/25 + 2/25 - 3

y = -x/25 -73/25

⟹Answer:

➧Lucas can cut the wire into 12 pieces.

Step-by-step explanation:

⟹Lets Solve!

⟹The first step is to convert [tex]\frac{3}{4}[/tex] into [tex]\frac{}{16}[/tex] !

      To do this we must find what number multiplied by 4 equals 16.

16 ÷ 4 = 4

⟹Now we know our multiplier is 4. So lets multiply the numerator and denominator by 4.

[tex]\frac{3}{4} * \frac{4}{4} = \frac{12}{16}[/tex]

[tex]\frac{12}{16}[/tex]

⟹Next we just divide  [tex]\frac{12}{16}[/tex] by [tex]\frac{1}{16}[/tex].

[tex]\frac{12}{16}[/tex] ÷ [tex]\frac{1}{16}[/tex] = 12

➧Lucas can cut the wire into 12 pieces.

Woohoo! Brainliest appreciated! Hope I helped!

Based on the original length of the wire and the length Lucas requires, he will have 12 pieces.

The wire is 3/4 feet long and each piece required will be 1/16 feet.

The number of pieces in total is:

= Length of wire / Length of pieces

Solving gives:

= 3/4 ÷ 1/16

= 3/4 × 16/1

= 48/4

= 12 pieces

In conclusion, Lucas will have 12 pieces.

Answer:

Step-by-step explanation:

Wait... this doesn’t make sense because it doesn’t tell you if there was tax, how many friends there were, or tips.

Answer:

16/y = x

Step-by-step explanation:

You cannot solve for the question yet. However, you can create an equation!

we know that each person paid 16 dollars.

We don’t know how much the bill was or how many people were there.

So out equation looks like;

z/y = x

or

z * x = y

z = how much each person paid.

y = how much each person paid.

x = how many people paid.

Substitute with what we know.

16/y = x

16 * x = y

Now you will be able to substitute for either x or y to find either answer.

Step-by-step explanation:

16. What is P(red, yellow, blue)?

P(red, yellow, blue)=  6/16= 3/8.

4/16+ 1/16+ 1/16= 6/16= 3/8

17. What is P(orange, yellow)?

P(orange, yellow)= 1/8

1/16+1/16= 2/16= 1/8

18. P(green, blue, purple)?

P(green, blue, purple)=  5/8

7/16+1/16+2/16= 10/16= 5/8.

19. P(pink)?

P(pink)=0

There is no pink color.

20. P(red, orange, yellow, green, blue, purple)?

P(red, orange, yellow, green, blue, purple)= 16/16= 1.

4/16+ 1/16+ 1/16+ 7/16+1/16+2/16 =16/16= 1.
