y=10-8x

2(10-8x)-4x=40

20-16x-4x=40

-20x=20

x=-1

y=10-8(-1)=18

(-1,18)

Answer:

(-1, 18)

Step-by-step explanation:

(2y-4x=40)x2

4y-8x = 80

4y-8x+y+8x=80+10

5y = 90

y = 90/5

y = 18

Substituting y into the first equation:

18 + 8x = 10

8x =-8

x = -1

Answer:

☘️9+5x+16

☘️ 25+5x or 5(5+X)

Answer:

42

Step-by-step explanation:

It's just saying that 1/2 * x = 70, and if we multiply both sides by 2, we get

x=140.

we check if that number is true by finding 80% of 140.

4/5 * 140 = 112. So that means 140 is the number we want

30% of 140 is 3/10 * 140, which is 420/10, which is 42

Answer:

6

Step-by-step explanation:

70/84 = 5/N

Answer:

34.30

Step-by-step explanation:

$14.70 is 30% of $49 so

The total would be $34.30 after the discount

But the discount is %14.70

Answer:

Try line 2. It lines up with the most points

Answer:

f(-1) = 3/2

Step-by-step explanation:

y = 3(2)^-1

2^-1 = 1/2^1

1/2^1 = 1/2

3 x 1/2 = 3/2

Answer:

11.4

Step-by-step explanation:

By Pythagoras Theorem:

[tex]x^{2} = {7}^{2} + ( {4}^{2} + {8^{2}}) \\ \\ x^{2} = 49+(16 + 64)\\ \\ x^{2} = 49+80\\ \\ x^{2} = 129 \\ \\ x = \sqrt{129} \\ \\ x = 11.3578167 \\ \\ x = 11.4[/tex]

Answer:

X = 8

Step-by-step explanation:

A triangle's degrees always add up to 180, this is a right triangle meaning that one of the degrees is 90, and we see the other one is 54, so we add these together and subtract them from 180 and set that equall to 3x+12.

Answer:

(x,y) ---→ ( x + 3 , y + 1 )

Step-by-step explanation:

Hello There!

All we have to do is pick one letter and count the units from the preimage to the translated image

To get to A' you have to from A and go up one unit to the right 3 units

So the translation is 1 unit up 3 units to the right or (x,y) ---→ ( x + 3 , y + 1 )

Answer:

A (50)

Step-by-step explanation:

Mean is the total numbers added up divided by the # of numbers.

There are 6 numbers.

51 + 60 + 80 + 32 + 47 + 30 = 300

300/6 = 50

Therefore, the answer is A.

Answer:

A

Step-by-step explanation:

Because to find the mean you add up all the numbers.

51+60+80+32+47+30=300

Then your suppose to divide by the sum.

300/6=50

Complete question :

An ice cream stand uses the expression 2 + 0.5x2 to determine the cost (in dollars) of an ice cream cone that has x scoops of ice cream. How much does an ice cream cone with 5 scoops cost?

Answer:

$14.5

Step-by-step explanation:

Give the expression for the cost of ice cream cone with x scoops of ice cream :

Cost = 2 + 0.5x²

Cost of ice cream cone with 5 scoops of ice cream.

x = 5

Cost = 2 + 0.5(5²)

Cost = 2 + 0.5(25)

Cost = 2 + 12.5

Cost = 14.5

Hence, the cost of ice cream is $14.5

Answer:

C

Step-by-step explanation:

the answer is C because the 2 angles are congruent, making it the same degree

second one 13/313

Answer:

Step-by-step explanation:

1.   perpendicular slope will be the negative of the reciprocal

2.  so this will be -3 ( since the reciprocal of 1/3 is 3 and its negative is -3

3.  So use the values given for x and y (3,-4)

4.   substitute in the given equation using the -3 for the slope instead of 1/3

5.  To find a new b we substitute  for x and y

5.  y = 1/3x + 10

6.  -4 =  -3 (3) + b

7.   -4= -9+ b

8. b = 5

Equation of the line will be y = -3x + 5

Answer:

yes

of you plus 213+55=268

then divide it 268÷4

there you will get the final answer

Answer: answer is (B. Yes. Dividing the total cost by 4 is the same as multiplying by 1/4

Step-by-step explanation:

because when there is a fraction you flip it upside down and multiply and you get a similar

Answer: [tex]37000+2500n[/tex]

Step-by-step explanation:

Given

John makes $82,000 per year after 18 years

If he would have to get a raise of $2500 per year

Suppose he starts with a salary of [tex]x[/tex]

after the first year, his salary would be

[tex]\Rightarrow x+2500[/tex]

After 2 years, the salary would be

[tex]\Rightarrow x+2500+2500=x+2\times 2500[/tex]

Similarly, after n years salary is

[tex]\Rightarrow x+2500n[/tex]

For 18 years, it is

[tex]\Rightarrow x+2500\times 18=82,000\\\Rightarrow c=82,000-45,000=\$\ 37,000[/tex]

So, after n years of working salary is [tex]37,000+2500n[/tex]

Answer:

4x+4y-4

Step-by-step explanation:

Lets simplify step by step:

5y - 8x - 7- y + 12 x + 3 = 5y +-8x +-7 + -y + 12x + 3

Now let’s combine the like terms:

5y +-8x +-7 + -y + 12x + 3

(-8x + 12x) + (5y + -y) + (-7 + 3)

So the answer would be 4x+4y-4

Hope this helps :)
