Answer:

b.) All real numbers.

Step-by-step explanation:

4 (<em>a </em>+ 3) = 12 + 4<em>a </em>

4<em>a</em> + 12 = 12 + 4<em>a </em>

4<em>a </em>+ 12 - 12 = 12 + 4<em>a </em>- 12

4<em>a </em>= 4<em>a </em>

4<em>a</em>/4 = 4<em>a</em>/4

0 = 0

All possibilities of other <em>real </em>number can fit into the equation. Hence, the answer is b.) All real numbers.

4(a + 3) = 12 + 4a
4a + 12 = 12 + 4a
0 = 0

Therefore, the solution to the equation is all real numbers.

Answer:

5.2

Step-by-step explanation:

To find the height of the plant after 7 weeks, we need to find out the equation of the line of best fit and plug in 7 for x. We already have our y - intercept, which is 1,  and we have a point on the x axis for which the y coordinate is an integer, (5, 4). Since we already have the y - intercept of +1 we have y = mx + 1. Since this applies to (5,4) we can plug this in to our equation. This is then 4 = 5m + 1. Subtracting 1 from both sides, we get 3 = 5m. Dividing by 5, we receive m = 3/5. Since now we have our slope, we can plug in 7 and find out our answer. Plugging in 7 we receive, y = 3/5 * 7 + 1, which is equal to y = 4.2 + 1. This means that y = 5.2, so 5.2 is our answer.

What are the x- and y-intercepts of the graph of 5x-4y= -20
lakkis [162]

To find the intercepts, we can set the opposite variable equal to 0 and solve.

Let's find the x intercept first.

5x - 4(0) = -20

5x = -20

Divide both sides by 5.

x = -4

<h3>The x intercept is -4.</h3>

Now let's find the y intercept.

5(0) - 4y = -20

-4y = -20

Divide both sides by -4.

y = 5

<h3>The y intercept is 5.</h3>
