Answer:

y=7x

Step-by-step explanation:

slope intercept form is y=mx+b.

m is the slope (rise over run) and b is your y- intercept. you leave y as it is. if the line is going down, you have a negative slope. hope this helped :)

I really need help with this section

Tpy6a [65]

Looks like you did most of it.

The next step would be setting them equal to 105, like the problem suggests.

$5z+3x+7x=105$

$15x=105$

$x=7$

Then we can plug back in to find the numbers.

$5*7=35$

$3*7=21$

$7*7=49$

$35+21+49=105$

The three numbers are $35, 21, 49$ .

Hope this helps.

頑張って!

Lucie drank 3/4 of a pint of bottled water. One serving of the water is 7/8 of a pint. How much of a serving did she drink.

attashe74 [19]

7/8
3/4
I'm order for them to have the same denominator you need to multiply so:
¾×2=6/8
So she drank 6/8 pints of water

Which inequality is represented by the graph?y > -2/3x + 1y < -2/3x + 1y < -3/2x + 1y > -3/2x + 1

Tanya [424]

Answer:

$y < -\frac{3}{2}x+1$

Step-by-step explanation:

Given:

From the graph shown,

The broken line means that the inequality sign will be either < or >.

The shaded region is to the left of the broken line. This means that $y < f(x)$ .

Now, in order to find equation of line, we need slope and y-intercept.

From the graph, the y intercept is at $(0,1)$ . So, y intercept is 1.

Also, if we consider two points $(0,1)\textrm{ and }(2,-2)$ on the line, then slope is given as:

$m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=\frac{-2-1}{2-0}=\frac{-3}{2}=-\frac{3}{2}$

Therefore, the equation of the line is given as:

$y=mx+b\\y=-\frac{3}{2}x+1$

But as the shaded region is to the left of the line,

∴ $y$ is the correct answer.
