Answer:

(8x+15)=(7x+17){ being alternative angle}

8x+15=7x+17

8x-7x=17-15

x=2

here,

8x+15= 8×2+15

16+15=31

7x+17

7×2+17

14+17

again

(8x+15)+y=180°( being straight angle)

31+y=180

y=180-31

y= 149

In the given figure, Angles (8x + 15) and (7x + 17) are equal

because they form pair of Alternate interior angles.

$8x + 15 = 7x + 17$

$8x - 7x = 17 - 15$

$x = 2$

So,

$8x + 15$

$( 8\times 2) + 15$

$16 + 15$

$31 \degree$

now, as we can see Angle y and (8x + 15) are forming linear pair; so their sum measures 180°

$(8x + 15) + y = 180$

$31 + y = 180$

$y = 180 - 31$

$y = 149 \degree$

fredd [130]

The statements which are true are;

Choice B: The baker uses 1/2 cup of sugar for every cup of water because 1/2 ÷ 1/4 = 1/2.
Choice E: The baker uses 2 cups of water for every cup of sugar because 1/2 ÷ 1/4 = 2.

<h3>Ratios and Proportions</h3>

Since the baker uses 1/2 cup of water for every 1/4 cup of sugar.

Considering proportions; we have;

1 cup of water for every 1/2 cup of sugar

2 cups of water for every cup of sugar;

This is because, 1/2 ÷ 1/4 = 2.

How do u slove this for y intercept?<br><br><br> (4, 1); slope=3/2

Valentin [98]

Answer:

y-intercept=-5

Step-by-step explanation:

y=mx+b m/slope=3/2 the point is (x,y)/(4,1)

1=3/2(4)+b

1=12/2+b

1=6+b

Answer:

1.) $slope=2$

2.) $slope=-3$

3.) $slope=\frac{1}{4}$

4.) $slope=-\frac{4}{5}$

Step-by-step explanation:

The unit rate is also known as slope. Slope is the change in the y values over the change in the x values:

$(x_{1},y_{1})\\\\(x_{2},y_{2})\\\\\frac{y_{2}-y_{1}}{x_{2}-x_{1}}=slope$

However, with certain graphs, the slope can be found in a simpler manner.

You start at one point and move across the y-axis, then move along the x-axis until you reach another point on the same line.

Make sure you move on the y-axis first, then the x-axis. Record the slope as spaces moved in each $\frac{y}{x}$

When you move up, the number will be positive $(\frac{+y}{x})$ . If you move down, the number will be negative $(\frac{-y}{x})$ .
If you move to the right, the number will be positive $(\frac{y}{+x})$ . If you move to the left, the number will be negative $(\frac{y}{-x})$ .
