Choose the graph of the linear equation. Y = X + 6

Answers

Answer:

A

Step-by-step explanation:

y = x + 6

Compare to y = mx + b.

b = 6

m = 1

A slope of 1 is a positive slope, so the line has to go up to the right.

A value of 6 for b means the y-intercept is 6.

If x and y are in direct proportion and y is 45 when xx is 15, find y when x is 4.

Answers

Answer:

y = 12

Step-by-step explanation:

the equation is

y = 3x

You find the constant or proportionality by put y/x

(15,45) is in the form (x,y)  The x is 15 and the y is 45.  Put this in the form y/x and you get 45/15 or 3.  3 is the constant of proportionality.

y = 3x

y = 3(4)

y = 12

y = 12

Jabari had two equations to solve. Both had two unknowns, x and y. Jabari could use them to solve each other. That's called (_______). Jabari decided to (_______) using the substitution method. First, he had to turn the x's in one equation into y's. He subtracted 2y from both sides of the first equation x+2y = 4. This made x = 4−2y.
Next, he substituted the expression 4−2y for x in (_______). Now he had (4-2y)−2y = 6.
Jabari saw that the two 2y's were like terms. He knew that collecting like terms is a way to (_______). He combined the y's to get 4−4y = 6.
From there, he subtracted 4 from both sides to get −4y=2. Now it was easy to evaluate the expression down to a single value. The problem's solution was (_______).

Here, we know that on each month 1 cm every month so it's increased 24 cm after 24 months

Therefore

H = 52 + m

H = 52 + 24

H = 76 cm

Thus, The height of the plant is 76 cm after 24 months.
