Negative 34 means (-34)

times means to multiply, then

$-34\times1567$

To do it without a calculator we will make -34

-30 + -4, then multiply -30 by 1567 and multiply -4 by 1567 then add the two answers

$-4\times1567=-6268$ $-30\times1567=-47010$

Then add the answers

$-34\times1567=-6268+-47010=-53278$

The answer is -53278

THIS IS THE FOURTH TIME I HAVE POSTED THIS QUESTION. I HAVE BEEN STUCK ON THIS SAME QUESTION FOR AN HOUR

So the culture banner size has length x, width x (since it is square)
The sports banner has length x+12, width x.

The area of the sports banner is length x width = x(x+12) = x²+12x.

Now, lets look at the tiles.

- The monomial, x, a factor of the expression is the width of the sports banner.

- The binomial (x+12) is the length of the spots banner (this is given!)

- The second degree term of the expression x²+12 is x², the area of the culture banner

- The first degree term of the expression x²+12x is 12x, it represents the increase in area, since the area went from x² to x²+12x

I just need help with three, four, and seven. Solve the system of linear equations, and determine if the equation has one soluti

likoan [24]

3. If $y=5x+9$ and $y=3x-2$ , then

$5x+9=3x-2\implies2x+9=-2\implies2x=-11\implies x=-\dfrac{11}2$

Then

$y=5\left(-\dfrac{11}2\right)+9=-\dfrac{55}2+9=-\dfrac{37}2$

(only one solution)

4. If $y+2=4x$ , then $y=4x-2$ . So we're told that $4x-5=4x-2$ but this is impossible, because that would that for any $x$ , we have -5 = -2. This is false, so this system has no solution.

7. "y is 6 less than 3 times x" means $y=3x-6$ . "x is 2 more than one-third of y" means $x=\dfrac13y+2$ . Solving the second equation for $y$ gives $y=3x-2$ , which would mean $3x-6=3x-2$ . But for the same reason as in (4), there is no solution. For any value of $x$ , this equation gives the false conclusion that -6 = -2.
