Answer:
2x+2y = 8
x – 2y = 4
3x=12
x=12/3=4
x=4
2x+2y=8
2(4) + 2y = 8
8+2y = 8
2y=8-8
2y=0
y=0/2=0
2(4)+2(0)=8
8+0=8
x+y=8
x-y=4
2x=12
x=12/2=6
6+y=8
y=8-6=2
6+2=8
2x+2y=4
x-y=4
2x+2y=4
2(x-y=4)
2x+2y=4
2x-2y=8
4x=12
x=12/4=3
2(3)+2y=4
6+2y=4
2y=4-6
2y=-2
y=-2/2=-1
2(3)+2(-1)=4
6+-2=4
x+2y=8
-(x+3y=4)
x+2y=8
-x-3y=-4
-1y=4
y=4/-1=-4
x+2(-4)=8
x+-8=8
x=8+8=16
Which graph represents a function
Answer:
The top left.
Step-by-step explanation:
You can use the vertical line test in order to prove if something is a function. If you place a vertical line on the graph and it intersects more than one point on the x-axis, it is not a function. Functions do not have overlapping x variables.

Students in a poetry class are writing poems for their portfolios. The teacher wants them to write stanzas with certain numbers of lines each. Lucy wrote 9 short stanzas and 9 long stanzas, for a total of 198 lines. Quincy wrote 9 short stanzas and 6 long stanzas, for a total of 156 lines. How many lines do the two sizes of stanzas contain?
Answer:
x = 8
y = 14
the short stanzas contain 8 lines
the long stanzas contain 14 lines
Step-by-step explanation:
lets call the short stanzas x
and the long stanzas y
using given information, you can make this equation
9x + 9y = 198
you can also make this equation
9x + 6y = 156
simplify the first equation
9x + 9y = 198
9x = 198 - 9y
x = 198/9 - y
x = 22 - y
substitute x for 22 - y in the second equation to find y
9(22 - y) + 6y = 156
198 - 9y + 6y = 156
-9y + 6y = -42
-3y = -42
y = 14
substitute y for 14 in the first equation to find x
9x + 9y = 198
9x + 9*14 = 198
9x + 126 = 198
9x = 198-126
9x = 72
x = 72/9
x = 8

Find the volume of the figure in cubic centimeters.
Answer:
755.16 cm³
Step-by-step explanation:
We can separate this into two parts -- the bottom rectangular prism and the top triangular prism.
The volume of the bottom part is 12*4*14 = 672 cm³
For the triangular prism, we have an equilateral triangle, with sides 4cm, as well as a length of 12cm. We can find the area of the triangle and multiply it by 12 for our answer. The area of an equilateral triangle is [tex]\frac{\sqrt{3} }{4} 4^{2}[/tex], which is approximately 6.83 -- we can multiply that by 12 to get 83.16 cm³
Add these 2 up to get 755.16 cm³ as our answer

Step-by-step explanation:
Your uncle gives you $10 and you save $2 a week. The expression 10 + 2w gives the amount you save after w weeks. How many terms are in the expression What is the coefficient in the expression
Answer:
2 terms
Step-by-step explanation:
Step one:
given data
we are told that your uncle gives you $10 and you save $2 a week
the expression for the situation is
let the total be y
[tex]y=10 + 2w[/tex]
From the expression, there are two terms
the first term is the constant term which is 10
while the second term is 2w, the coefficient is 2

Answer:
The intercepts of a graph are points at which the graph crosses the axes. The x-intercept is the point at which the graph crosses the x-axis. At this point, the y-coordinate is zero. The y-intercept is the point at which the graph crosses the y-axis. At this point, the x-coordinate is zero.
To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. For example, lets find the intercepts of the equation \displaystyle y=3x - 1y=3x−1.
To find the x-intercept, set \displaystyle y=0y=0.

We can confirm that our results make sense by observing a graph of the equation as in Figure 10. Notice that the graph crosses the axes where we predicted it would.
This is an image of a line graph on an x, y coordinate plane. The x and y-axis range from negative 4 to 4. The function y = 3x – 1 is plotted on the coordinate plane

HOW TO: GIVEN AN EQUATION, FIND THE INTERCEPTS.
Find the x-intercept by setting \displaystyle y=0y=0 and solving for \displaystyle xx.
Find the y-intercept by setting \displaystyle x=0x=0 and solving for \displaystyle yy.
EXAMPLE 4: FINDING THE INTERCEPTS OF THE GIVEN EQUATION
Find the intercepts of the equation \displaystyle y=-3x - 4y=−3x−4. Then sketch the graph using only the intercepts.
