Answer:
The answer is 3
Step-by-step explanation:
Given f(x) = -3x + 3, solve for x when f(x) = 9.
Answer:
x = -2
Step-by-step explanation:
f(x) = -3x + 3
f(x) = 9
-3x + 3 = 9
Subtract 3 from both sides;
-3x = 6
Divide both sides by -3
x = -2

What is the slope of the line?
Answer:
-1
Step-by-step explanation:
Remember, slope is rise/run
Start from a point on the line and count up and over until you reach another point on the line.
For example, start from (0,-2), count up and left until you get to (-2,0). This gets you 2/2, which reduces to 1.
Since the line represents a negative slope, the slope is -1.
Arthur sits in the park reading a newspaper, then starts walking home at a constant pace. He stops for bagels, then walks the rest of the way home.
1. What does the x-axis represent in this situation?
2. What does the y-axis represent?
3. During which parts of the graph does Arthur's distance from home decrease?
4.When is Arthur waiting for bagels? Explain how you know.
5. If Arthur's pace had not been constant after leaving the bagel shop, which part of the graph would change? Explain how that part of the graph would change.
6. If Arthur had spent less time reading his newspaper, which part of the graph would change? How would that part change?
Answer:
y =87
Step-by-step explanation:
Answer:
1. What does the x-axis represent in this situation?
The x-axis represents time.
2. What does the y-axis represent?
The y-axis represents distance.
3. During which parts of the graph does Arthur's distance from home decrease?
Sections 2 and 4.
4. When is Arthur waiting for bagels? Explain how you know.
Section 3. The flat areas represent times when Arthur is not moving. We know that the first flat area shows Arthur reading his newspaper, and the third is when he reaches home; so the second flat area represents the time in which Arthur is waiting for bagels.
5. If Arthur's pace had not been constant after leaving the bagel shop, which part of the graph
would change? Explain how that part of the graph would change.
The part of the graph that would change is part 4. If his pace was not constant, section 4 would not be uniform, and would have many abnormalities. Essentially, Arthur would be randomly speeding up and slowing down.
6. If Arthur had spent less time reading his newspaper, which part of the graph would change? How would that part change?
If Arthur had spent less time reading his newspaper, the whole graph would change. Section one would be shorter, and the entire line would also be shorter. The distance on the graph from the beginning of section 1 to the end of section 5 would be reduced.

Find the perimeter of the triangle
Answer:
60 ft
Step-by-step explanation:
(x+13) = (3x-1) = (6x-22) since the triangle is equaililateral
(x+13) = (3x-1) (we only need to chose 2)
-2x=-14
x=7
after this, we just need to plug in the number for x
3(7)-1= 20--->since the triangle has 3 congruent sides, they all have the distance, so 20x3=60
60FT

HELPPPPPP I HAVE BEEN TRYING FOR AGES
Answer:
1.88 to 2 decimal places
Step-by-step explanation:
First, I plugged in 1.8 and 1.9:
1.8^3-3*1.8=0.432
1.9^3-3*1.9=1.159
Then, I plugged in 1.85:
1.85^3-3*1.85=0.78
Next, I plugged in 1.87 to get the answer closer to 1:
1.87^3-3*1.87=0.93
Finally, I plugged in 1.88 to get even closer to 1:
1.88^3-3*1.88=1.00
Hope this helps!
Answer:
Step-by-step explanation:
1.8=-0.568 is too small
1.9=0.159 is too big
1.87=-0.70797 is too small
1.88=0.004672 is too big
Next, I plugged in 1.87 to get the answer closer to 1:
1.87^3-3*1.87=0.93
Finally, I plugged in 1.88 to get even closer to 1:
1.88^3-3*1.88=1.00
1.875=-0.033203125 is too small
so it should be 1.88 to 2 decimal places

AB≈8.54
Answer:
X = root 73
Step-by-step explanation:
Basically you have to use the slope formula and slope intercept aka y = mx+b to find the equation. The equation is: 8/3x minus 10/3 and if you were to set this equation to zero and plug in root 73 you would get 0 meaning this answer is true/right.
The graphed line shown below is y = 5 x minus 10.
On a coordinate plane, a line goes through (2, 0) and (3, 5).
Which equation, when graphed with the given equation, will form a system that has no solution?
y = -5 x + 10
y = 5 (x + 2)
y = 5 (x - 2)
y = -5 x - 10
Step-by-step explanation:
For 2 lines to form a system with no real solution, the slope of the lines have to be equal and the y-intercept is different.
Hence the answer is y = 5(x + 2).
Under a given correspondence two triangles are congruent if the three sides of the one are equal to the three corresponding sides of the other
The above is known as
(a)SSS congruence of two triangles
(b)SAS congruence of two triangles
(c)ASA congruence of two triangles (d)RHS congruence of two right-angled triangles
Answer:
(a)SSS congruence of two triangles
Step-by-step explanation:
Congruence is a relationship that expresses the similarity between two triangles. The relationship between two triangles with their three sides being congruent is termed as the side-side-side (SSS) congruence property of the triangles. This implies that the two triangles are similar with respect to their three sides.
In corollary, since the three sides of the two triangles are congruent, then the three angles respectively would be congruent.
The Medina's went out to eat at Chili's. If there bill was 65.20 and they gave 1p
their server a 15% tip, how much did they leave for a tip? *
Answer:
The Medinas left $9.78 for a tip
Step-by-step explanation:
Percentages
The Medinas went out to eat at Chilli's and the bill was $65.20. They tipped 15% to their server.
This percentage is calculated over the amount of the $65.20 bill, thus the tip was:
15% of 65.20 = 15/100 * $65.20 = $9.78.
The Medinas left $9.78 for a tip

What is JK? please explain/show your work on how you got your answer
Answer:
JK = 20 mStep-by-step explanation:
A line segment that connects two midpoints of the sides of a triangle is called a midsegment.A triangle midsegment is parallel to the third side of the triangle and is half of the length of the third side.Point J is midpoint of side HI as HJ = JI
Point K is midpoint of side GI as GK = KI
JK is midsegment as connects the midpoints of the sides
JK = 1/2HG as per property of midsegment
6x - 4 = 10x/26x - 4 = 5x6x - 5x = 4x = 4JK = 6x - 4 = 6*4 - 4 = 24 - 4 = 20 m
Answer:
[tex]JK=20m[/tex]
Step-by-step explanation:
It is given in the diagram that IJ = JH and IK = KG. Therefore, by the definition of a midpoint, we know that J and K are the midpoints of segments IH and IG respectively. Then, it can be concluded that JK is a midsegment by the definition of a midsegment. The Midsegment Theorem states that a midsegment connecting the midpoints of two sides of a triangle is parallel and half of the length of the third side. Thus, we know that JK is half of HG. Now, we can set up the following equation to solve for x:
[tex]JK = \frac{1}{2}HG\\6x-4=\frac{1}{2}(10x)[/tex]
Solving for x, we get:
[tex]6x-4=\frac{1}{2}(10x)\\6x-4=5x\\x-4=0\\x=4[/tex]
Therefore, [tex]JK = 6x - 4 = 6(4) - 4=24-4=20 m[/tex].

The graph below shows a system of equations:
The x-coordinate of the solution to the system of equations is
Answer:
solution is (-2, 2) so x-coordinate of solution is -2
Step-by-step explanation:
Answer:
-2
Step-by-step explanation:
First, we have to write down both equations.
y = x + 4
3y = -2x + 2
Now we already have an equation that we can plug into the other equation.
= 3(x + 4) = -2x + 2
= 3x + 12 = -2x + 2
= 5x + 12 = 2
= 5x = -10
x = -2
Now we know that x = -2, and the question asks for the x-coordinate, which is -2.

Bill is a builder.
On Monday he made mortar mix.
He used 24kg of sand and 5kg of cement.
On Tuesday he will make the same type of mortar mix.
He will use 36kg of sand.
How much cement does he need to make the same type of mortar mix?
Answer:
7.5kg
Step-by-step explanation:
Given that:
Monday:
Mass of sand = 24 kg
Mass of cement = 5 kg
Tuesday :
Mass of sand = 36 kg
Let mass of cement = c
Mass of cement required to make the same type of mortar mix
Mass of Sand = mass of cement
24kg = 5kg
36kg = c
By cross multiplication :
24 * c = 5 * 36
24c = 180
Divide both sides by 24
c = 180 / 24
c = 7.5 kg
Hence mass of cement required is 7.5 kg
