Answer:

The x - intercept of the line is (-4, 0).

Step-by-step explanation:

The x-intercept is the point from which the graph passes through the x-axis.

At the x-intercept y = 0.

The provided line is: $-4x-2y=16$

Substitute y = 0 in this equation to determine the x-intercept as follows:

$-4x-2y=16\\-4x-(2\times 0) = 16\\-4x = 16\\x=-\frac{16}{4} \\=-4$

Thus, the x-intercept is (-4, 0).

Refer to the graph below.

Determine the zeroes of 10x2−5=35

OLEGan [10]

Answer:

x = +2, x = -2

Step-by-step explanation:

The equation to solve in this problem is

$10x^2-5=35$

The first step we do is to subtract 35 on both sides of the equation, so we get:

$10x^2-5-35=0\\10x^2-40=0$

Now we simplify the equation by dividing both terms by 10:

$\frac{10x^2-40}{10}=0\\x^2-4=0$

Now we observe that the term on the left is the difference between two squares, so it can be rewritten using the property:

$a^2-b^2=(a+b)(a-b)$

Where here,

a = x

b = 2

So we can rewrite the equation as:

$x^2-4=0\\(x+2)(x-2)=0$

And this equation is zero when either one of the two factors is zero, so the two solutions are:

$x+2=0\rightarrow x=-2\\x-2=0 \rightarrow x=+2$

The quantities x and y are proportional.

Maslowich

Answer:

The value of the constant of proportionality r is 1

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

Find the value of the constant of proportionality r

For x=5.8, y=5.8

substitute

The linear equation is

therefore

The value of the constant of proportionality r is 1

105,159 rounded to the nearest ten thousand

IceJOKER [234]

If you look at the hundereds place you see it is under the number 5 which means you would drop 1, 5, & 9 and the answer would be 105,000. If the number was above 5 you would have had to make it 106,000.

A taxi service charges one dollar for the first 1/10 of a mile then $.10 for each additional 1/10 of a mile after that

Evgen [1.6K]

Answer:

y = 1.00+0.10 x (if this is what you meant)

Step-by-step explanation:

Given that a taxi has a minimum charge of 1 dollar upto 1/10 mile and adds 0.10 for every additional 1/10 mile.

If a person travels <=1/10 miles his charges are 1 dollar

If he travels >1/10 miles charges are 1 dollar +0.10(extra miles 1/10)

Let y be the charges and x be the no of 1/10 miles.

Then the equation for y in terms of x would be

y =1.00 +1/10(x)

y = 1.00+0.10 x
