Graph the linear equation find three points that solves the equation 2y=5x+11
Julli [10]

Answer:

<h3>Attachment</h3>

Step-by-step explanation:

Convert to the slope-intercept form (<em>y = mx + b</em>):

2y=5x+11             <em>divide both sides by 2</em>

\dfrac{2y}{2}=\dfrac{5x}{2}+\dfrac{11}{2}\\\\y=\dfrac{5}{2}x+\dfrac{11}{2}

We choose any three x values ​​and calculate the y value:

for x = -1

y=\dfrac{5}{2}(-1)+\dfrac{11}{2}=-\dfrac{5}{2}+\dfrac{11}{2}=\dfrac{6}{2}=3\to A(-1,\ 3)

for x = 1

y=\dfrac{5}{2}(1)+\dfrac{11}{2}=\dfrac{5}{2}+\dfrac{11}{2}=\dfrac{16}{2}=8\to B(1,\ 8)

for x = -3

y=\dfrac{5}{2}(-3)+\dfrac{11}{2}=-\dfrac{15}{2}+\dfrac{11}{2}=-\dfrac{4}{2}=-2\to C(-3,\ -2)

Mark the points on the coordinate plane and draw a line through the given points.

A bowl of fruit contains only strawberries and grapes. For every 2 strawberries in a bowl there are 5 grapes.
sdas [7]

Answer:

See Explanation

Step-by-step explanation:

Given

Let:

S \to Strawberry

G \to Grape

The given parameter can be represented as:

S : G = 2 : 5

Required

The question is incomplete as what is required is not stated.

Possible questions could be to determine the number of strawberries given a certain number of grapes, and vice versa

Take for instance

Calculate the number of grapes when there are 20 strawberries

We have:

S : G = 2 : 5

This becomes

20 : G = 2 : 5

Express as fraction

\frac{20}{ G} = \frac{2 }{5}

Make G the subject

G = 20 * \frac{5}{2}

G = 10 * 5

G = 50

<em>i.e. 50 grapes</em>

<em>Apply the same method given a certain number of grapes</em>
