Answer:

x=-2,y=-2

Step-by-step explanation:

x+y=-4

x=-4-y--(3)

substitute (3) in (1)

5(-4-y) -3y=-4

-20-5y-3y=-4

-8y=16

y=16/-8

y=-2

substitute y in (3)

x=-4-(-2)

x=-2

Answer:

3 + 4x

Step-by-step explanation:

Let "a number" be x.

Therefore "four times a number" is 4 multiplied by x which is 4x.

Now add 3 for "3 plus".

3 + 4x

Answer:

Our equation would be: 3 + 4x.

Let's say x=8

That would now make our equation:

3 + 4(8) =

Step-by-step explanation:

But let's solve this equation :)

First, we would add 3+4, to get 7.

Then, we would multiply the 7 by 8.

Lastly, we know 7 x 8 = 56

So, 3+4(8)= 56

But we could also create a function statement out of this.

Our statement for this equation would be:

When x equals 8 the answer or in algebraic terms the "output" is 56.

Answer:

let the unknown angle be x

we know. sum of angles of a triangle is 180°

so,

130+20+x=180

150+x=180

x=180-150

x=30°

Answer:

-32

Step-by-step explanation:

if we multiply - 2 and -6 it becomes positive so it will be 12.

-2 multiply 22 will be -44

12 - 44 is -32.

answer : -32

you distribute so you do -2 times -6 which is 12. then -2 times 22 which is -44.

you end up with 12 - 44, which equals -32.

Answer:

168

Step-by-step explanation:

first find out how many rows of squash there are

21 = x + 2x

21 = 3x

7 = x

then find out how many rows of tomatoes there are

7 × 2 = 14

if there are 12 plants per row, we can multiply

14 × 12 = 168

Gardener Gary planted 168 tomato plants

Let the rows of tomato be x and the rows of squash be y.

So, we have:

x + y = 21

The statement twice as many rows of tomatoes as rows of squash means that:

x = 2y

Substitute x = 2y in x + y = 21

2y + y = 21

This gives

3y = 21

Divide by 3

y = 7

Substitute y = 7 in x = 2y

x = 2 * 7

x = 14

This means that Gary planted 14 rows of tomato.

The number of tomato plants is then calculated using

Tomato plants= 14 * plants per row

This gives

Tomato plants = 14 * 12

Evaluate the product

Tomato plants = 168

Hence, Gardener Gary planted 168 tomato plants

Answer:

(f + g)(x) = 4x + 1

Step-by-step explanation:

Given f(x) = 3x - 1 and g(x) = x + 2, find (f + g)(x):

We can rewrite (f + g)(x) as f(x) + g(x), and solve the composite functions through addition:

f(x) + g(x) = (3x - 1) + (x + 2)

Combine like terms:

f(x) + g(x) = 3x + x + 2 - 1 = 4x + 1

Therefore, (f + g)(x) = 4x + 1.

a) The linear function that models the amount of water after t minutes is given by:

[tex]V(t) = 200 + 12t[/tex]

b) It takes 92 minutes to completely fill the pond.

Item a:

Then, the function is:

[tex]V(t) = 200 + 12t[/tex]

Item b:

It takes t minutes to fill the pond, t is found for which:

[tex]V(t) = 1304[/tex]

Then

[tex]200 + 12t = 1304[/tex]

[tex]12t = 1104[/tex]

[tex]t = \frac{1104}{12}[/tex]

[tex]t = 92[/tex]

It takes 92 minutes to completely fill the pond.
