The coordinate grid shows points A through K. What point is a solution to the system of inequalities? y > −2x + 10 y > 1 o
jarptica [38.1K]

Point B is a solution to the system of inequalities  

<h3>Further explanation  </h3>

Straight-line equations are mathematical equations that are described in the plane of cartesian coordinates  

General formula  

\large{\boxed{\bold{y-y_1=m(x-x_1)}}

or  

y = mx + c  

Where  

m = straight-line gradient which is the slope of the line  

x1, y1 = the Cartesian coordinate that is crossed by the line  

c = constant  

The formula for a gradient (m) between 2 points    

\large{\boxed{\bold{m=\dfrac{y_2-y_1}{x_2-x_1}}}

If the intersection of the x-axis (b, 0) and the y-axis (0, a) then the equation of the line:  

ax + by = c

It says inequality if there are symbol forms like <, >, ≤ or ≥  

Whereas linear inequality can have forms:  

ax + by> c, ax + by ≥ c , ax + by <c , ax + by ≤ c  

In graphical form, line inequality can be  

• dashed line because y does not include equals to  

• a solid line because y includes equal to  

For line inequality (positive coefficient y)  

ax + by ≥ c then the solution is shaded upwards  

ax + by ≤ c then the solution is shaded down  

(Picture attached)

The line :

\displaystyle y>-2x+10

intersect x-axis at point : 5,0

Intersect y-axis at point : 0,10

And the solution  is shaded upwards  

\displaystyle y=\frac{1}{2}x-2

intersect x-axis at point : 4,0

Intersect y-axis at point : 0,-2

And the solution  is shaded upwards  

And the point located in the shaded plane of the two inequality is point B and I

True or False. When flipping a penny 14 times the penny likelihood of landing on heads is 7 times.
Elenna [48]

Answer:

True

Step-by-step explanation:

Since a penny has head and tails, each has 1/2 chance to land on heads or tales, so 14*1/2=7, so true.

A scientist mixes water (containing no salt) with a solution that contains 35% salt. She wants to obtain 105 ounces of a mixture
Naya [18.7K]

Answer:

60 oz of water to add

45 oz of 35% salt solution should be used

Step-by-step explanation:

Let x = amt no. ounces in the first solution

and  105 - x = amt no. of ounces in the second solution

Ist solution contains 0% salt

2nd solution contains .35(105 - x) salt

.15(105= amt of salt in mix

So.

amt of salt in 1st solution + amt of salt in 2nd solution = amt of salt in the mix

0 + .35(105 - x) = .15(105)

Let's get rid of the fractions by multipying thru the equation by 100

35(105 - x) = 15(105)

3675 - 35x = 1575

-35x = -2100

x = 60 oz of water to add

105 - 60 = 45 oz of 35% salt solution should be used
