What is the X intercept of 5x + 2y = 6

Mathematics

Brilliant_brown [7]3 years ago
7 0

Answer:

x intercept at x = 6/5 (= 1.2 )

Step-by-step explanation:

recall that the x-intercept occurs at y = 0, hence we substitute this into the equation and solve for x

5x + 2y = 6, for y = 0

5x + 2(0) = 6

5x + 0 = 6

5x = 6    (divide both sides by 5)

x = 6/5

Alex Ar [27]
Answer:

7.5 quarts of olive oil remain.

Explanation:

Let

q = quarts of olive oil remain

<span>25%</span> of olive oil remains means that <span>75%</span> has been used.

22<span>12</span> quarts = 22.5 quarts used

<span><span>22.5.75</span>=<span>q.25</span></span>

Multiply both sides by .25 to isolate q.

<span><span>22.5.75</span><span>(.25)</span>=<span>q.25</span><span>(.25)</span></span>

<span><span>5.625.75</span>=q</span>

<span>7.5=<span>q</span></span>

Part B
ziro4ka [17]

The linear equation that has a slope of -7 and crosses the x-axis at (3, 0) is:

y =  -7x + 21

<h3>How to find the linear equation?</h3>

A general linear equation is:

y = a*x +b

Where a is the slope and b is the y-intercept.

The slope must be equal to the limit found in part a, and you say that it is equal to -7, so the slope is -7. And for how is written the problem, I understand that it crosses the x-axis at x = 3.

Then we will have:

y = -7*x + b

Such that, when x = 3, y = 0, then:

0 = -7*3 + b

21 = b

Then the linear equation is y = -7x + 21
