Which equation describes the function shown in the table?
Answer:
The first one
Step-by-step explanation:
Because it already give you the y-intercept and you can solve x by doing 4 to 7 have to add 3 and x only have to add 1. It will give you a slope 3/1, so it is 3.
y=3x+1
I don’t understand this
Answer:
so, for each of the questions you have to change the expression into slope intercept form, then use that equation to graph a line on the graph.
i'll help you out:
11. y= 3/2x+5 (0,5) (-4,2 )
12.y= -2x-5 (0,-5) (-1,-3)
13. y= -2x-3 (0,-3) (-1,-1)
14. y= x-4 (0,-4) (4,0)
Step-by-step explanation:
the first expression is the slope intercept form and the parenthesis are the points.
i hope this helps :)

y=−2x−5
y=2x−2
Answer:
(-3/4, -7/2)
Step-by-step explanation:
y= −2x − 5
y= 2x − 2
2y = -7
y = -7/2
y= 2x − 2
-7/2 = 2x - 2
2x = -3/2
x = -3/4
(x,y) = (-3/4, -7/2)
Answer:
-3/4 or -7/2

Answer:
Do 16 times 8 times 3 and then when you get the answer add 6
Step-by-step explanation:
Answer:
137 [tex]ft^2[/tex]
Step-by-step explanation:
1. Approach
Break up the given figure into smaller figures. One can break up this figure into a rectangle, and a triangle. After doing so, one can calculate the area of each of the smaller figures, and then add up the values.
2. Calculate the area of the triangle
If one were to cut the top figure off, one would get a triangle with a base of (3ft), and a height of (6ft). One can calculate the area of the figure using the formula;
[tex]\frac{base*height}{2}[/tex]
Substitute;
[tex]\frac{6*3}{2}\\\\= \frac{18}{2}\\\\\ 9[/tex]
3. Calculate the area of the rectangle;
Now, one is left with a rectangle with dimensions (16ft), and (8ft). To find the area of this figure, use the formula;
[tex]base * height[/tex]
Substitute;
[tex]16 * 8\\\\= 128[/tex]
4. Find the area of the whole figure
Now add the area of the triangle, and the area of the rectangle together.
(Rectangle) + (Triangle)
= 128 + 9
= 137

Solve for y
what is 3x +2y =x +2(2y-3z)
Answer:
y = x + 3 z
Step-by-step explanation:
Determine the equation of the line passing through the points A(–1, 6) and B(2, 4).
Answer:
y = -2/3x + 5 1/3
Step-by-step explanation:
Find the slope:
4 - 6 / 2 - (-1) = -2/3
Put it in point-slope form:
y - 6 = -2/3(x + 1)
rearrange:
y - 6 = -2/3x - 2/3
y = -2/3x + 5 1/3

solve the system 2x+4y=16 5x +3y=19 then find the value of y/x
Answer:
I would change 2x+4y=24 into x=12–2y
To do that, divide both sides by 2 and then subtract 2y on each side.
After that, substitute for x. 3x+2y=19 would become 3(12–2y)+2y=19.
Then solve.
3(12–2y)+2y=19
36–6y+2y=19
-4y+36=19
-4y=-17
y=4.25
Then, substitute y in either equation.
Either this:
3x+2y=19
3x+2(4.25)=19
3x+8.5=19
3x=10.5
x=3.5
Or:
2x+4y=24
2x+4(4.25)=24
2x+17=24
2x=7
x=3.5
Or you could solve it in the equation you created in the beginning:
x=12–2y
x=12–2(4.25)
x=12–8.5
x=3.5
The coordinates where the lines intercept are (3.5, 4.25).
Sorry for the long answer!

Answer:
Yes it is an integer
Step-by-step explanation:
On a coordinate plane, point B(–6, 1) is translated to B prime(–3, –2). Indira uses these steps to find a rule to describe the translation.
Step 1 Substitute the original coordinates and the translated coordinates into (x, y) right-arrow (x + a, y + b):
B (negative 6, 1) right-arrow B prime (negative 6 + a, 1 + b) = B prime (negative 3, negative 2)
Step 2
Write two equations:
Negative 6 + a = negative 2. 1 + b = negative 3.
Step 3
Solve each equation:
Negative 6 + a = negative 2. a = negative 2 + 6. a = 4. 1 + b = 3. b = negative 3 minus 1. b = negative 4.
Step 4
Write the translation rule:
(x, y) right-arrow (x + 4, y minus 4)
Which corrects Indira’s first error?
Indira should have substituted B (negative 6, 1) right-arrow B prime (negative 3 + a, negative 2 + b) = B prime (negative 6, 1) in Step 1.
Indira should have written the equations Negative 6 + a = negative 3 and 1 + b = negative 2 in Step 2.
Indira should have solved the equations to find that a = negative 8 and b = negative 2 in Step 3.
Indira should have written the translation rule (x, y) right-arrow (x minus 4, y + 4) in Step 4.
What is the measure of the angles 4,5 & 6
9514 1404 393
Answer:
∠4 = 145°
∠5 = ∠6 = 35°
Step-by-step explanation:
Angles 5 and 35° are corresponding angles, so are congruent.
Angles 5 and 6 are vertical angles, so are congruent.
Angles 4 and 35° are a linear pair, so are supplementary.
∠4 = 180° -35°
∠4 = 145°
∠5 = ∠6 = 35°
Find the measure of the missing angle !
Answer:
38+?=111
DCB=111-38
DCB=73
Answer:
73°
here's your solution
=> angle D + angle C = angle CBQ
=> Because we know that exterior angle
equal to sum of two opposite interior angles
=> D +C = CBQ
=> C + 38° = 111°
=> C = 111 - 38
=>. C = 73°

Jake's baby pool is empty. His mom fills it with a garden hose at a rate of 2 gallons per minute. What is the initial value for the scenario described?
Answer:
Initial value = 0
Step-by-step explanation:
The initial value is the amount of water in Jake's baby pool before his mom began to fill it with water at a rate of 2 gallons per minute.
We are told that the pool was empty, therefore, the initial value = 0.
Answer:
0
