Answer:

B. None

Step-by-step explanation:

We can use substitution for this.

First solve the first equation for y:

y + 7x = -3

y = -7x - 3

Now, substitute this expression in for y in the second equation:

14x + 2(-7x - 3) = 6

We can then solve for x:

14x - 14x - 6 = 6

0 - 6 = 6

-6 = 6

However, we know that -6 ≠ 6, so there are no solutions to this system. Thus, the answer is B, none.

Hope this helps!

Answer:

no solutions

Step-by-step explanation:

y+7x =-3

14x+2y = 6

Multiply the first equation by -2 to eliminate x and y

-2y-14x = 6

14x+2y = 6

--------------------------

0 = 12

This is never true, so there are no solutions

iragen [17]

Answer: A false, B true, C true

Step-by-step explanation:

A) intercept with y axis

That means x=0

y= 3*0-2

y= -2 So A is false

B) intercept with x axis

That means y=0

0= 3x-2

2=3x

2/3= x B is true

C) The form of linear function is

f(x)= mx +n, where m is the slope

In this case m= 3 so C is true

Jose Has scored 28,24,26,27,and 21 Points in his five basketball game so far. How many points does he need to score in his next
Step2247 [10]

Answer:

The correct answer is 24.

Step-by-step explanation:

Jose wants to have an average mean of 25 points per game in his 6 basket ball matches.

Total points Jose plans to achieve in 6 games is 25 × 6 = 150.

Points score by him in the first five matches are 28, 24, 26, 27 and 21.

Total points in 5 matches is 126.

Thus the points he need to score in his next game to have an average mean of 25 is given by 150 - 126 = 24.

kompoz [17]

Answer:

<em>Tommy earned $55</em>

Step-by-step explanation:

<u>Proportions</u>

Tommy and Mark made $88 raking leaves for Mrs. Bopp. They were paid the same rate and Tommy raked for 5 hours while Mark raked for 3 hours.

The total time both raked is 5+3=8 hours. The rate Mrs. Bopp paid them was $88/8 = $11 per hour.

Tommy raked 5 hours, so he earned 5*$11 = $55

Tommy earned $55

Solve this system. Write your answer as an ordered pair. -5x + y = -3 3x - 8y = 24
Ivanshal [37]

Hello there, this is how we will solve your problem.\

here is the equation you gave us.

{\huge{\boxed{\mathbb{EQUATION}}}

\begin{bmatrix}-5x+y=-3\\ 3x-8y=24\end{bmatrix}

we can isolate x and say x=\frac{-3-y}{5}

Now here is our equation, \begin{bmatrix}3\left(-\frac{-3-y}{5}\right)-8y=24\end{bmatrix} After we simplify it we get \begin{bmatrix}\frac{9-37y}{5}=24\end{bmatrix}, solve this and we get that y=-3, Before we said x equals -\frac{-3-y}{5}, So now we can plug in our value that y equaled, and now we have \frac{-3-(-3)}{5}. Two negatives equal a positive and we get that x=0.
