James planted a tree in his backyard. The initial height is 5 ft tall. It grows 1/2 ft a year after that.
Answer:
New height = 11/2 ft
New height = 5 + 1/2(N)
Step-by-step explanation:
Given:
Initial height = 5 ft
Grown height = 1/2 ft
Find:
New height
Computation:
New height = Initial height + Grown height
New height = 5 + 1/2
New height = 11/2 ft
Equation;
New height = 5 + 1/2(Number of year)
New height = 5 + 1/2(N)
can someone tell me how to solve 8th grade slope! I'll put you as brainliest!!
Answer:
Step-by-step explanation:
Well, the formula to find slope is y2-y1 / x2-x1
Here's an example:
(2,12) (4,24)
12-24 / 2-4 =
-12/-2 or 6
You would use:
(y=mx+b) to find an entire equation, including the y intercept
Let me know if this helps, and if it doesn't, I hope I'll be able to explain it better.

y = x + 8
4x – 2y = -12
Answer:
x = 14
y = 22
Step-by-step explanation:
y = x + 8
4x - 2y = -12
Solve
_____________
Since we see that the first equation has y alone, we can substitute it into the values of y in the second equation.
4x - 2(x + 8) = -12
Distribute :
4x - (2(x) + 2(8)) = -12
4x - 2x +16 = -12
Combine like terms :
2x + 16 = -12
Subtract 16 from both sides :
2x = -28
Divide 2 from both sides to get x alone :
x = 14
Now that we know what x is, substitute it in the first equation to get y :
y = (14) + 8
y = 22
Answer:
(2 , 10) or x = 2 & y = 10
Step-by-step explanation:
y = x + 8
4x – 2y = -12
1. Substitute x + 8 in for the y in the other equation.
2. Solve for x
3. Take the solution for x and substitute the number in for the x in y = x + 8.
4. Solve for y.
5. Your answer is the result.
4x - 2(x + 8) = -12 Distributive Property
4x - 2x - 16 = -12 Combine like terms
2x - 16 = -12 Isolate the x, so start by moving -16
+ 16 +16
2x + 0 = 4 Delete the 0. It is a place holder you don't need
2x = 4 Isolate the x by dividing both terms by 2.
2 2
x = 2
y = x + 8 Substitute the 2 in for x and solve the one step equation.
y = 2 + 8
y = 10

pls help Find the area of the shape shown below.
\text{ units}^2 units
2
Answer:
8 sq units
Step-by-step explanation:
area of square in middle is 2 x 2 = 4 sq units
area of one triangle is 1/2(2)(2) = 2 sq units
however, there are two triangles, so you have to double 2 to get 4
4 + 4 = 8
Answer:
8cm^2
Step-by-step explanation:
Method 1: It's a trapezium, so take the top length, (6cm), add it to the bottom length (2cm) = 8cm which is then divided by 2 (4cm) then multiplied by the height (2cm) giving an area of 8cm squared.
Method 2: area of the square = 2 x 2 = 4cm^2
Triangle 1: 2 x 2 = 4, divided by 2 = 2cm^2
Triangle 2: same as triangle 1.
Total: 4 + 2 + 2 = 8cm^2
If y = 2x + 1 and x = 4, then y =
Answer:
9
Step-by-step explanation:
First, plug-in 4 for x to get the equation y = 2(4) + 1
Then using PEMDAS we multiply 2 and 4 to get 8 and then add the one to make y = 9
9. What is the range of the relation [(4, 2), (1, 1), (0, 0). (1.-1). (4, -2) ?
Answer:
{-2,-1,0,1,2}
Step-by-step explanation:
When we are talking of the range, we are referring to the possible y-values the relation can take
Hence, a set of y-values will represent the range of the relation
we have this as:
{2, 1 , 0, -1 , -2}
Arranging in order, we have ;
{-2,-1,0,1,2}

Exit Which algebraic expression below represents four multiplied by a number? A. 4 – x B. x + 4 C. 4x D.
Answer:
C. 4x
Step-by-step explanation:
Considering the options
A.4 – x - This is the difference between 4 and a number x
B. x + 4 - This is the sum of a number x and 4
C. 4x - This is the product of a number x and 4
D.
From the above, option C which is the product of x and 4 is same as four multiplied by a number.
A. y+2 = -4(X-8)
B. y- 8 = -4(x + 2)
C. y+ 8 = -4(x-2)
D. y-2 = -4(x+8)

Given the x1 and y1 = given point.
Substitution x1 = 2 and y1 = -8 in the equation.
[tex] \begin{cases} x_1 = 2 \\ y_1 = - 8 \end{cases} \\ y - ( - 8) = - 4(x - 2) \\ y + 8 = - 4(x - 2)[/tex]
Hence, the solution is C choice.
