The graph of y=f(x) is shown below. Determine the value of x when f(x)=3?
Answer:
f(x) = 3
y = 3
So from the graph the value of y = 3 is found D.
Thus x = -3.
All the best!
What is (8f–9)–(9f–6)
Hey there!
(8f - 9) - (9f - 6)
= 8f - 9 - 9f + 6
= 8f - 9f - 9 + 6
= -f - 3.
Steps :-
Remove the brackets.Bring the like terms together.Simplify the equation.Hope it helps ya!
Answer:
-1 ( f +3) or -f - 3
Step-by-step explanation:
( 8f - 9 ) - ( 9f - 6 )
Add like terms:
8f - 9f = -1f = -f
-9 - -6 = -3
-f - 3
simplify:
-1 ( f +3)
The equation of a line given two points needs to be found. Samuel claims that slope-intercept form will generate the equation and Helena claims that point-slope form will find the equation. Who is correct? Explain your reason by describing both forms.
Answer:
Helena is correct in saying that the point-slope form will generate the equation. The point-slope form is written as:
y-y₁ = m(x-x₁), where,
m = (y₂-y₁)/(x₂-x₁) is the slope of the line
(x₁,y₁) and (x₂,y₂) are the coordinates of the two points
On the other hand, the slope-intercept form is written as:
y = mx + b, where,
m is the slope of the line
b is the y-intercept
In this case, since only two points were given, the y-intercept of the line is not readily known. Thus, it is only through the point-slope form that the equation of the line can be determined. This is because it only requires the substitution of the x and y-coordinates of the points in the equation.

x < 3 is the solution to which of the following compound inequalities?
a) x < 5 and x < 3
b) x < 5 or x < 3
c) x > 4 and x < 3
d) x > 4 or x < 3
x<1 AND x<5, the intersection is x<1 because those values are in both but it is A

Ratio of 5:
4:15
Answer:
1.5 : 3:5 = smallest ratio 1 : 2.3333333333333
Step-by-step explanation:
Large Parallelogram 12 small parallelogram 8 = 12/8 = 1.5 scale factor
Large triangle 14 and small triangle 4 = 14/4 = 3.5 scale factor
1.5 : 3:5 = smallest ratio 1 : 2.3333333333333
If you erased 1/4 of the shaded part below, how much of the original figure will be shaded?
Answer:
[tex]\frac{5}{12}[/tex]
Step-by-step explanation:
[tex]\frac{2}{3} -\frac{1}{4}[/tex]
Find the least common denominator (LCD).
[tex]\frac{2 * 4 }{3*4} - \frac{1*3}{4*3}[/tex]
= [tex]\frac{8}{12} - \frac{3}{12}[/tex]
Substract.
[tex]\frac{8-3}{12}[/tex] = [tex]\frac{5}{12}[/tex]
Hence, [tex]\frac{5}{12}[/tex] of the original figure will be shaded.

The price of an item has been reduced by $9.94. The original price was $62.45. What is the price now?
Answer: The price now is $52.51
Step-by-step explanation: To find the price after a reduction, we need to subtract the amount of the reduction from the original price. In this case, we have:
Original price = $62.45
Reduction = $9.94
Price after reduction = Original price - Reduction Price after reduction = $62.45 - $9.94
Price after reduction = $52.51
We can also check our answer by adding the reduction to the price after reduction and seeing if we get back the original price:
Price after reduction + Reduction = Original price $52.51 + $9.94 = Original price $62.45 = Original price
This confirms that our answer is correct.
Hope this helps, and have a great day! =)
The expression 5n + 2 can be used to find the total cost in dollars of bowling where n is the number of games bowled and 2 represents the cost of shoe rental. How much will it cost Vincent to bowl 3 games?
quickly please.
Answer: $17
Step-by-step explanation:
5n+2 is the equation we start off with.
He plays 3 games, and since n represents the number of games bowled, we subsitute n with 3.
Our equation looks like this:
5(3)+2
If you solve the equation, you get:
5(3)+2
=15+2
=17
The answer is $17.

Find the value of f(-5).
==========================================================
Explanation:
Locate -5 on the x axis number line. Draw an arrow going upward until you reach the function curve. Then move horizontally until you reach the y axis. You should arrive at y = 4. Therefore, f(-5) = 4 and it means the point (-5, 4) is on the function curve.
Check out the diagram below.
Jamar purchases a savings bond for $3000. If the bond earns 3% interest for a term of 5 years, what will the total value of Jamar's investment be at the end of 5 years?
Answer:
450$
Step-by-step explanation:
3000*3%=3000*0.03
3000*0.03=90
90*5=450
The cost of the previous year's booths and prizes for Class Fun Day was $504. This year's cost of the prizes and booths increased by 8% from the cost of the previous year. Mark knew that the budget for the class day is $725.76. He claimed that 70% of the money will be spent on prizes and the booths.
Use reasoning to explain how Mark's claim is incorrect. What percent of the money will be spent on the prizes and the booths?
Eli is in the business of manufacturing phones. He must pay a daily fixed cost to rent the building and equipment, and also pays a cost per phone produced for materials and labor. Let C represent the total cost, in dollars, of producing p phones in a given day. The table below has select values showing the linear relationship between p and C. Determine the additional cost to produce each phone.
Answer:
1 phone costs $175
Step-by-step explanation:
The skeleton equation is C = Px + R, where C is total cost, P is the number of phones, x is the price of phones, and R is the rent
We can find the rate of change by finding slope:
1475 - 775/5 - 1 = 700/4 = 175
Now we can input 775 for total cost, and 1 as the number of phones to find the rent
775 = 1(175) + R
775 = 175 + R
600 = R
The rent is 600
1 phone costs 175

Using a physical or diagram model of the Sun, the Moon, and the Earth to explain the reason for seasons
Answer:
https://spaceplace.nasa.gov/seasons/en/
Answer:
The way that Earths axis is tilted is what determines the season that it is. for example when the Northern hemisphere tilts toward the Sun, it's summer in the Northern Hemisphere. And when the Southern hemisphere tilts toward the Sun, it's winter in the Northern Hemisphere. This is because when a hemisphere is tilted towards the sun, that hemisphere is getting direct rays from the sun.
Sara needs to take a taxi to get to the movies. The taxi charges $6 for the first mile, and then $2.75 for each mile after that . If the total charge is $14.25, then how far was Sara's taxi ride to the movie ?
Answer:
The total miles it took to go to the movies is 4 miles (counting the first mile that cost $6)
Step-by-step explanation:
Variables:
x = per mile
y = total
Equation:
y = 6 + 2.75x
Given:
y = 14.25
Work:
y = 6 + 2.75x
14.25 = 6 + 2.75x
2.75x = 14.25 - 6
2.75x = 8.25
x = 8.25/2.75
x = 3
Answer:
So the first step is to subtract $6 from 14.25.
We get 8.25.
divide 8.25 by 2.75, to find out how many miles (after the 1st mile) Sarah's ride was.
8.25/2.75 = 3. So 3 + 1 = 4.
The total mileage length to get to the movies was 4 miles.

(a) 8b + 5 = 133
(b)
8b = 133 - 5
8b = 128
b = 16
step 1 8b + 5 = 133
step 2 8b = 133 - 5 (moving the five that was plusing have to turn into minus)
8b = 128)( move the 8 that is timing with the b from timing turns into dividing
the answer would be b = 16
