Which equation represents grants path? A. y=2-4x B. y=4-x/2 C. y=6-x/4 D. y=8-2x

EleoNora [17]

Answer:

Step-by-step explanation:

recall that the point-slope form of a linear equation is given by

y = mx + c

Rearranging so that it is in the same form as the answer choices, we get

y = c + mx

where m is the slope and c is the y-intercept

we note the following observations

1) The line goes from top left to bottom right, this means that the slope is negative, hence m has to be negative. (in our case, all the choices have negative x)

2) The line crosses the y-axis at y = 4, this means the y-intercept is 4 and hence c = 4.

If we look at the choices, only choice B satisfies both observations (that m is negative and c = 4)

David and Carlo ran laps to train for the long-distance running team. The ratio of the number of laps David ran to the number of

weeeeeb [17]

Answer:

Carlo ran 33.3% of the miles.

Step-by-step explanation:

It sounds like David ran 2 laps for every 1 lap that Carlo ran. So, for every 1 mile that Carlo ran, David ran 2 miles, which means if you add both miles together: 1 mile (Carlo) + 2 miles (David) = 3 miles, that Carlo ran 1/3 of the miles, and David ran 2/3 of the miles. In percentages, it means Carlo ran 1/3=0.333 or 33.3% and David ran 2/3=0.666 or 66.6%

The population of a heard of cattle numbered was 5000 to begin with and was 10,000 after 10 years. If the population was growing

Lapatulllka [165]

Answer:

$r=0.0718$ . The closest value from your given choices is C)r=0.69

Step-by-step explanation:

To solve this we are using the standard exponential growth equation:

$f(t)=A(1+r)^t$

where

$f(t)$ is the final population after $t$ years

$A$ is the initial population

$r$ is the growth rate in decimal form

$t$ is the time in years

We know from our problem that the initial population is 5000, the final population is 10000, and the time is 10 years, so $A=5000$ , $f(t)=10000$ , and $t=10$ .

Let's replace the values and solve for $r$ :

$f(t)=A(1+r)^t$

$10000=5000(1+r)^{10}$

Divide both sides by 5000

$\frac{10000}{5000} =(1+r)^{10}$

$2=(1+r)^{10}$

Take root of 10 to both sides

$\sqrt[10]{2} =\sqrt[10]{(1+r)^{10}}$

$\sqrt[10]{2} =1+r$

Subtract 1 from both sides

$\sqrt[10]{2}-1=r$

$r=\sqrt[10]{2}-1$

$r=1.0718-1$

$r=0.0718$

We can conclude that the growth rate of our exponential equation is $r=0.0718$ . The closest value from your given choices is C)r=0.69

1) Which of the following is NOT the same as 4 : 20 ?* 8:40 6:50 5:25 1:5

adoni [48]

6:50 is the answer! Hope this helps. You can figure this out by crossing out the ones you KNOW are factors of 4 and 20. And 6:50 is NOT a factor of them . Hope this helped!!

Find the measure of the complement and supplement of 3y

andrew11 [14]

Answer:

Step-by-step explanation:

x + y = 180

x = 3y + 8

3y+8 + y = 180

4y = 172

y = 43 degrees

x = 180-43 = 137 degrees
