Answer:

-4

Step-by-step explanation:

4x+3y=-1

3x + y=-7​

Solve for Y

3x+y=-7

-3x.      -3x

y= -3x - 7

Plug in Y into the top equation

4x + 3 (-3x - 7) = -1

Distribute the Parenthesis

4x -9x-21=-1

Combine Like terms

-5x = 20

Divide by -5 on both sides

20/-5

x = -4

<h2>Hi ☘</h2>

1-A 2-A 3-B

- 104 \geqslant  - 8b - 8

put -8 near -104

- 104 + 8 \geqslant  - 8b

- 96 \geqslant  - 8b

b will be alone.

\frac{ - 96}{ - 8}   \geqslant   \frac{ - 8b}{ - 8}

b  \geqslant 12

Answer A

3m - 7 >  - 4

3m >  - 4 + 7

3m > 3

\frac{3m}{3}  >  \frac{3}{3}

m > 1

Answer A

İf

m \geqslant 1

The answer would be D

But answer A

- 4x + 4 >  - 16

16 + 4  >  + 4x

20 > 4x

\frac{20}{4}  >  \frac{4x}{4}

x < 5

Answer B

If a school cafeteria needs c cans of soup each week for each student, and if there are s students in the school, for how many w
Sphinxa [80]

Answer:

x/(cs)

Step-by-step explanation:

Let w represent the number of weeks we're feeding students soup.

w\,\text{weeks}\times\dfrac{c\,\text{cans}}{\text{student}\cdot\text{week}}\times s\,\text{students}=x\,\text{cans}\\\\w=\dfrac{x}{c\cdot s}\qquad\text{divide by $c\cdot s$}

The coordinates of A, B,and C in the diagram are A(p,4), B(6,1), C(9,q). What equation correctly relates p and q?
murzikaleks [220]
I don't see any diagram. So, I'll just wing it.

Value of q:
p, 6, 9 ⇒ there is a difference of 3. The sequence increases by 3. So, it can be assumed that the p is equal to 3. A(p,4) ⇒ A(3,4)

Value of q:
4, 1, q ⇒ there is a difference of 3. The sequence decreases by 3. So, it can be assumed that q is equal to -2. C(9,-2)
 
        p        q
A     3        4     ⇒ 3 + 4 = 7
B     6        1     ⇒ 6 + 1 = 7
C     9       -2    ⇒ 9 + (-2) = 7

Notice that the sequence has an equation of p + q = 7.
