I’ll give you brainliest!!!! What is the slope of the line containing (-4.3) and (2,-1)

Answer:

a) x = 5

b) x = 12

Step-by-step explanation:

x + 3 = 8

Subtract 3 on both sides.

x = 8 - 3

x = 5

x - 5 = 7

Add 5 on both sides.

x = 7 + 5

x = 12

Answer:

[tex]a)x = 5 \\ b)x = 12[/tex]

Step-by-step explanation:

[tex]a)x + 3 = 8 \\ x = 8 - 3 \\ x = 5[/tex]

[tex]b)x - 5 = 7 \\ x = 7 + 5 \\ x = 12[/tex]

Answer:

-65

Step-by-step explanation:

-80 - -15

Two minuses become plus

= -80+15

Subtract and keep the sign of the higher number

= -(80-15)

= -65

Answer:

I'm glad you asked!

Step-by-step explanation:

[tex]-80-(-15)[/tex]

= [tex]-80-(-15)[/tex]

= [tex]=-80+15[/tex]

[tex]=-65[/tex]

The answer is - [tex]65.[/tex]

Answer:

usas la sustitución para resolver esto

Step-by-step explanation:

Restar y

de ambos lados de la ecuación.

x = 7 − y

x − y = 1

Reemplazar todas las apariciones de x

en x − y = 1 con 7 − y

.

x = 7 − y

(7 − y) −y = 1

Restar y

de −y

.

x = 7 − y

7−2y = 1

Resuelve por y

en la segunda ecuación

x = 7 − y

y = 3

Reemplazar todas las ocurrencias de y

en x = 7 − y con 3

.

x = 7− (3)

y = 3

Simplifica 7− (3)

x = 4

y = 3

La solución al sistema de ecuaciones se puede representar como un punto.

Answer:

x = 8

[tex] m\angle A= 30\degree[/tex]

Step-by-step explanation:

By interior angle on one side of transversal postulate.

[tex] m\angle A + m\angle B = 180\degree \\

\therefore (6x - 18)\degree + (14x + 38)\degree = 180\degree \\

\therefore (20x + 20)\degree = 180\degree \\

\therefore 20x + 20 = 180

\therefore 20x = 180 - 20\\

\therefore 20x = 160\\\\

\therefore x = \frac {160}{20}\\\\

\huge \red {\boxed {\therefore x = 8}} \\\\

\because m\angle A= (6x - 18)\degree \\

\therefore m\angle A= (6\times 8- 18)\degree \\

\therefore m\angle A= (48- 18)\degree \\

\huge \purple {\boxed {\therefore m\angle A= 30\degree}} \\[/tex]

Answer:

If angle 2 = 110 then angle 4 = 110

360 = 110 + 110 + x

Angle 1 + Angle 3 = 140

Since vertical angles are equal, then Angle 1 = 140 / 2 = 70 degrees

Step-by-step explanation:

Step-by-step explanation:

∠3+∠4= 180°

Since ∠2 ≅ ∠ 4 and  ∠2= 110°

∠3= 180° - ∠4= 180° - ∠2= 180° - 110°= 70°

So proved

Answer:

False

Step-by-step explanation:

This is false because there are 5 numbers from 0 - 4 (0, 1, 2, 3, 4) so the probability will be 1/5 not 1/4.

The answer is 5 in a close dot going --->

Which is D.)

The picture is to show how it looks in Plato.

Answer: D.

Step-by-step explanation:

If they already have 565 cans and 87 will bring cans then we could represent it by the inequality  

87x + 565[tex]\geq[/tex] 1000  where x is the number of cans each guest much bring to meet the goal. so solve for x.

87x  + 565[tex]\geq[/tex] 1000

        -565     -565

87x [tex]\geq[/tex] 435

x [tex]\geq[/tex]  5  

since we now that x is 5  then A  and C can't be answers.

B can't be an answer in this case because 5 is excluded but they actually need at least 1000 bottles so 5 needs to be excluded.

Answer:

2, 3

Step-by-step explanation:

2. The leading coefficient is -3. When the leading coefficient is negative, the parabola opens down.

3. When the parabola opens down, it has a maximum point, but no minimum point. (when the parabola opens up, it has a minimum, but no maximum)

I hope this helps :)

The right statements about equation y=−3x^2+18x+23 is 2) The leading coefficient is negative and 3) The parabola has a maximum.

A parabola is a plane curve which is mirror-symmetrical and can be downward, upward, leftward and rightward shaped.

Second is true because when the coefficient is negative  the parabola opens down because their values starts decreasing.

Third is true because when the parabola opens down it has a maximum point and no minimum point. On the other hand when the coefficient is positive it opens up.

Answer:

A. <

Step-by-step explanation:

The symbol "<" means less than.

Comparing 4.589 with 4.958, 4.958 is greater than 4.589 by 0.369 (4.958 - 4.589).

So therefore, if we are to write 1 statement for both, we would say "4.589 is less than 4.958".

This can be written by using just symbols without words, thus, we have:

4.589 < 4.958.

The correct option is A. <

Answer:

240 m to nearest meter.

Step-by-step explanation:

h = -4.9t^2 + 68.6t

We need to convert this to vertex form to find the maximum value of h:

h = -4.9(t^2 - 14t)

h = -4.9[(t - 7)^2 - 49]

h =  -4.9(t - 7)^2 + 240.1

So maximum height is when t = 7 and it's 240.1 meters.

Answer: Option B.

Step-by-step explanation:

The price per ounce can be calculated as the amount of you paid divided the number of ounces that you get.

A) we have a table:

ounces          price

18                     $1.5

36                    $3.00

54                    $4.5

We can see that here we have a linear relationship. for example, the price for 18 ounces is $1.5

Then the price per ounce is:

p = $1.5/18 = $0.083

B) here we know that 15 oz cost $0.75, the price per ounce is:

p = $0.75/15 = $0.05

C) here we have 11 ounces, and the price is $2.20

then we have:

p = $2.2/11 = $0.2

Then we can conclude that the least expensive is option B.

The range of the data is 9.

Step-by-step explanation:

The frequency table shown is:

Age     Tally          Frequency

32        ||||                   4

33                              13

The range of a data set is the difference between the highest and the lowest value.

Range = Maximum - Minimum

Answer:

5/12 or 15/36

Step-by-step explanation:

Since he rolls two dice, he has a total probability of 6 times 6 = 36. The pairs, that he could add up to primes are (1,1), (2,1) * 2 (since he can get 1,2 as well), (1,4) * 2, (2,3) * 2, (3,4) * 2, (5, 2) * 2, (6,1) * 2, (5, 6) * 2. This is 1 + 2 + 2 + 2 + 2 + 2 + 2 + 2, which is equal to 15. This is a total of 15/36 possible ways, which is also equal to 5/12.

Answer:

r = 8

Step-by-step explanation:

15 = 1.5r+3

Subtract both sides of the equation by 3.

15-3 = 1.5r+3-3

12 = 1.5r

Divide both sides of the equation by 1.5.

12/1.5=1.5r/1.5

8 = r

r = 8

Answer:

[tex]8[/tex]

[tex]1.5r + 3 = 15 \\ 1.5r = 15 - 3 \\ 1.5r = 12 \\ r = \frac{12}{1.5} \\ r = \frac{120}{15} \\ r = 8[/tex]

Answer:

The order doesn’t matter, as the two events are probabilistically independent of one another. There are 13 spades in a standard 52 card deck, so the probability of drawing  the number 5 is 13/52 or 1/4. The probability of heads is 1/2. The probability of both occurring is the product of the two probabilities, or 1/4*1/2 = 1/8 or 12.5%.

Answer:

the probability of getting 5 from standard deck is 4/52 and probability to get tails from a flipped coin is 1/2

Step-by-step explanation:

as there are 4 parts in card i.e spade diamonds hearts and clubs which has 13 cards each from each 13 cards there are one 5 card so there are 4 cards with 5 number in standard deck

there is only one tails in a coin

Answer:

976cm^2

Step-by-step explanation:

Surface area:

Ara of cross section x 2 = 1/2 x 2 x 14 x 24 = 14 x 24 = 336

Area of base = 14 x 10 = 140

area of slope x 2 = 25 x 10 x 2 = 500

Total surface area = 500+140+336 = 640 + 336 = 973cm^2

Answer:

976 cm^2

Step-by-step explanation:

Area of triangle: 1/2bh

Area of rectangle b×h

2 Triangular ends 12×14=168 each So 336

2 sides 10×25=250 each So 500

1 base 10×14=140

Add: 140+500+336=976 square centimeters

Answer:

3 cm by 6 cm

Step-by-step explanation:

Represent the length and width by L and W.  

The perimeter is P = 2L + 2W, and here the perimeter is 18 cm.

Finally, L = W + 3 cm.  substituting W + 3 cm for L in the above equation, we get:

18 cm = 2(W + 3) + 2W, or (after reduction)

9 cm = W + 3 cm + W

Then 2W = 6 cm, or W = 3 cm.

Then the length is L = W + 3, or 3 cm + 3cm = 6 cm

The dimensions of the rectangle are 3 cm by 6 cm.

Check:  Does 2(3 cm) + 2(6 cm) = 18 cm?  Yes

Answer:

7.5 miles

Step-by-step explanation:

Given the equation d(t) = 0.5t, all you need to do is plug in the value of t.

They're asking what the Function equals, and they're giving you the value of the variable t.

To solve, write the equation d(15) = 0.5(15)

And if you simplify the right side of the equation, you'll find that

d(15) = 7.5

If t represents time, then you can conclude that Julio travels 7.5 miles in the time t, of 15 minutes.
