Answer:

-12y + 20

Step-by-step explanation:

First, you simplify each term:

apply the distributive property:

4 - 5y - 2 (3.5y) - 2 x -8

Multiply 3.5 by -2:

4 - 5y - 2 (3.5y) - 2 x -8

Multiply -2 by -8:

4 - 5y - 7y +16

Next, we simplify by adding terms:

Add 4 + 16:

-5y - 7y + 20

Subtract 7y from 5y:

-12y + 20

Hence the simplified form is -12y + 20

Step-by-step explanation:

6/7 12/14 18/21

Answer:

18.87 km/hr

Step-by-step explanation:

First boat is heading North with a speed of 10 km/hr.

Second boat is heading West with a speed of 16 km/hr.

Time for which they move = 2.5 hours

To find:

The speed at which the distance is increasing between the two boats.

Solution:

Let the situation be represented by the attached diagram.

Their initial position is represented by point O from where they move towards point A and point B respectively.

[tex]Distance = Speed \times Time[/tex]

[tex]Distance\ OA = 10 \times 2.5 = 25\ km[/tex]

[tex]Distance\ OB = 16 \times 2.5 = 40\ km[/tex]

We can use Pythagorean Theorem to find the distance AB.

AB is the hypotenuse of the right angled [tex]\triangle AOB[/tex].

According to Pythagorean theorem:

[tex]\text{Hypotenuse}^{2} = \text{Base}^{2} + \text{Perpendicular}^{2}\\\Rightarrow AB^{2} = OA^{2} + OB^{2}\\\Rightarrow AB^2 = 25^2 + 40^2\\\Rightarrow AB^2 = 2225^2\\\Rightarrow AB^2 \approx 47.17\ km[/tex]

The speed at which distance is increasing between the two boats is given as:

[tex]\dfrac{47.17}{2.5} \approx 18.87\ km/hr[/tex]

Answer:

r1 =6

r2 =8

t = ?

[(1/r1) * t] + [(1/r2)*t] = 1

t/6 + t/8 = 1

multiply by common denominator... 24

24 (t/6 + t/8 = 1)

4t + 3t =24

7t = 24

t = 24/7 = 3.4hrs

[tex]\boxed{\pink{\sf \leadsto Yes \ there \ is \ a \ solution \ of \ the \ given \ inequality .}}[/tex]

A inequality is given to us and we need to convert it into standard form and see whether if it has a solution . So let's solve the inequality.

The inequality given to us is :-

[tex]\bf\implies |2y + 3 | - 1 \leq 0 \\\\\bf\implies |2y+3|\leq 1 \\\\\bf\implies (|2y+3|)^2 \leq 1^2 \\\\\bf\implies (2y+3)^2 \leq 1 \\\\\bf\implies (2y)^2+3^2+2(2y)(3) \leq 1 \\\\\bf\implies 4y^2+9+12y - 1 \leq 0 \\\\\bf\implies 4y^2+12y+8 \leq 0 \\\\\bf\implies 4( y^2 + 3y + 2 ) \leq 0 \\\\\bf\implies y^2+3y +2 \leq 0 \:\:\bigg\lgroup \purple{\bf Standard \ form \ of \ inequality }\bigg\rgroup \\\\\bf\implies y^2y+2y+y+2 \leq 0 \\\\\bf\implies y(y+2)+1(y+2)\leq 0 \\\\\bf\implies ( y+2)(y+1)\leq 0 \\\\\bf\implies \boxed{\red{\bf y \leq (-2) , (-1) }}[/tex]

Let's plot a graph to see its interval . Graph attached in attachment .

Now we can see that the Interval notation of would be ,

[tex]\boxed{\boxed{\orange \tt \purple{\leadsto}y \in [-2,-1] }}[/tex]

I got it wrong so oof

Step-by-step explanation:

An open circle means that it isn't equal to the number so the sign would either be < or >

The number that the circle is on is -1 so x is either < or > to -1

x is anything to the left to -1 so the inequality would be x< -1

I hope this helps!!!

Answer:

256x * 16

Step-by-step explanation:

[tex](4x^{2} * 4)^{2}[/tex]

(4x * 4x * 4) * (4x * 4x * 4 )

(16x * 4 ) * ( 16x *4)

16x * 16x = 256x

4 * 4 = 16

256x * 16

hope this helped a little

* = multiply

The given expression without exponent is

[tex]4 \cdot 4 \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x[/tex]

Given :

[tex](4x^4)^2[/tex]

Explanation

We need to write the given without exponents

outside exponent is 2 . so we multiply the parenthesis twice

[tex](4x^4)^2\\4x^4 \cdot 4x^4\\16 \cdot x^4 \cdot x^4\\ 16 \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x\\4 \cdot 4 \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x \cdot x[/tex]

Answer:

2.6 tuna

Step-by-step explanation:

Amount of tuna salad rob has = 7.8ounces

Amount of sanndwiches made = 3sandwiches

If she had equal amount of tuna on each sandwiches

Amount of tuna in each = Total amount of tuna/Amount of sandwiches

Amount of tuna in each = 7.8/3

Amount of tuna in each  = 2.6 tuna

Hence she put 2.6 tuna in each sandwiches

Answer:  24 Pumpkin cupcakes.

Step-by-step explanation:

We know that:

They recently sold 6 Pumpkin cupcakes and 8 other cupcakes.

Then we can model this with the ratio  6:8

This means that for each 6 Pumpkin cupcakes sold, they also sell 8 of another type of cupcakes.

With this information, if they sell 56

Answer:

The distance of Jack's Father's work from home in miles is 45 miles.

Step-by-step explanation:

a) Data and Calculations:

Normal time taken by Jack's father to drive to work = 30 minutes

Time taken when traffic is bad = 1 hour longer

Speed when traffic is bad = 30 mph slower

Distance covered when traffic is bad, with time taken as 1 hour 30 minutes = time * speed = 1.5 * 30 = 45 miles

b) Jack's father normally drives at 90 mph (45 *2), this is why it normally takes him 30 minutes between his home and workplace when the traffic is not bad.  However, when traffic is bad, it takes him one hour longer and he drives at 30 mph slower.

Answer: y = x + 4

Step-by-step explanation:

y = mx + b

y is going up by 1 and x is going up by 4.

so y = x + 4.

to check if it's the correct answer plug in one of the numbers to x and y.

for example:

y = x + 4

2 = -2 + 4
