Mathematics

Ne4ueva [31]2 years ago
7 0

Answer:

y= ⅓x +2

Step-by-step explanation:

Since the graph is a linear graph, let's use the slope-intercept form to find its equation.

<u>Slope-intercept </u><u>form</u>

y= mx +c, where m is the slope and c is the y-intercept.

The y-intercept is the point at which the graph cuts through the y-axis. In this case, the y-intercept is 2.

Thus, y= mx +2.

Let's find the slope of the graph.

First, identify 2 pairs of coordinates from the graph:

(0, 2) and (3, 3)

Next, substitute these coordinates into the slope formula below:

\boxed{ \text{slope} = \frac{y _{1} - y_2 }{x_1 - x_2} }

slope

=  \frac{3 - 2}{3 - 0}

=  \frac{1}{3}

Thus, the equation of the graph is y= ⅓x +2.

Find the value of x.
lawyer [7]

Answer:

\huge\boxed{x=\sqrt{70}}

Step-by-step explanation:

ΔABC and ΔADB are similar (AAA).

Therefore the corresponging sides are in proportion:

\dfrac{AB}{AD}=\dfrac{AC}{AB}

Substitute:

AB=x\\AC=7+3=10\\AD=7

\dfrac{x}{7}=\dfrac{10}{x}       <em>cross multiply</em>

(x)(x)=(7)(10)\\\\x^2=70\to x=\sqrt{70}

5.5B+4R=285, point, 5, B, plus, 4, R, equals, 28
svet-max [94.6K]

Answer:

$285

Step-by-step explanation:

<u>Blueberries:</u>

B = number of pounds of blueberries bought

$5.50 = price of blueberries per pound

$5.50B = total price of B pounds of blueberries

<u>Blueberries:</u>

R = number of pounds of raspberries bought

$4 = price of raspberries per pound

$4R = total price of R pounds of raspberries

<u>Total:</u>

$5.5B + $4R

Since 5.5B+4R=285, then Amit spends in total on both types of berries $285

Good strategy for using slope formula
Fantom [35]
I personally use y2-y1 over x2-x1 because it's simple.  Plot two y values and two x values.  The first ones you plotted are x1 and y1, the others are x2 y2.  Now subtract y2-y1 and x2-x1.  Afterwards, divide the y value by the x value, that will give you slope.
