but they need the whole page to answer this question.
Hi there!
Let the first number be represented by X.
The second number (which is 2 more than four times the other), can be represented by 4X + 2.
We can now find the sum of this expression.
X + 4X + 2
Collect terms
5X + 2
The sum of the numbers is 18. Therefore we can set up the following equation.
5X + 2 = 18
Subtract 2.
5X = 16
Divide both sides by 5.
X = 16/5 = 3 1/5.
Therefore, the first number is 3 1/5. To find the second number we must plug in X = 3 1/5 into the expression 4X + 2
4 * (3 1/5) + 2 = 12 4/5 + 2 = 14 4/5
The two numbers are
~ Hope this helps you!
Y = mx + b
where m is the slope and b is the y-intercept.
1. 2x + 3y = 12
3y = -2x + 12
y = -2x + 4
y-intercept is 4
2. x - 4y = 20
-4y = -x + 20
y = -x - 5
y-intercept is 5
3. y = 2x - 9
this one is easy because it's already in standard form
y-intercept is -9
Answer:
24 units ^2
Step-by-step explanation:
The area of a trapezoid is found by
A = 1/2 (b1+b2) h where b1 and b2 are the bases and h is the height
A = 1/2( 8+4) *4
=1/2 (12)*4
= 24 units ^2
Answer: 9
Step-by-step explanation: So we need to write and solve an equation to solve for m, which is 12. Simply plug in 12 for m in the equation.
Step 1: 2-x/4+10
Step 2: 2-12/4+10 Plug 12 in for x
Step 3: 2-3+10 12 divided by 4 is 3 and 2-3 is -1
Step 4: -1+10=9 -1 + 10 is 9
