Step 1: Define
f(x) = 3x² - 7x
f(-2) is x = -2
Step 2: Evaluate
Substitute in x: f(-2) = 3(-2)² - 7(-2)Exponents: f(-2) = 3(4) - 7(-2)Multiply: f(-2) = 12 + 14Add: f(-2) = 26Find the volume of figure B

Sam bought a 7/8 -foot piece of wood to make some small boxes to hold his insect collection. He used 3/16 foot of wood for each box. Which equation can be used to show how many boxes Sam made?
Answer:
Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box
Step-by-step explanation:
Total piece of wood bought = 7/8 foot
Piece of wood used for each small box = 3/16 foot
Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box
= 7/8 foot ÷ 3/16 foot
= 7/8 × 16/3
= 7×16 / 8×3
= 112 / 24
= 4 16/24
= 4 2/3 small boxes
The equation is:
Number of small boxes Sam made = Total piece of wood bought / Piece of wood used for each small box

so store b would be the cheapest hope this helps please give me brainliest
Step-by-step explanation:
In which quadrant does the point (13, 18) lie
Answer:
Quadrant 1
Step-by-step explanation:
how I understood this is first understanding how a graph works. Once you understand that you can count 13 horizontal on the "X" Axis, then go 18 up on the "Y" axis. you should get a point in the upper left area and that area is called Quadrant 1. Say if 13 was negative instead of going horizontal east you would go horizontal west. And the point should end up in Quadrant 2. Any more questions feel free to ask me below.

If point P is Four-sevenths of the distance from M to N, what ratio does the point P partition the directed line segment from M to N into?
Answer:
m into5
Step-by-step explanation:
Answer:
ANSWER 4:3
Step-by-step explanation:
Given : A point P is 4/7 of the distance from M to N.
∴ Let the distance between M to N be d.
Also, the point P partition the directed line segment from M to N .
Thus , MN = MP+PN
Now, the ration of MP to PN will be :-
∴ Point P partitioned the line segment MN into 4:3.

line e has a slope of -2/9. line f is perpendicular to e. what is the slope of f
Answer:
9/2
Step-by-step explanation:
In order to find the slope of a line that is perpendicular to another line, you must find the opposite and reciprocal of that slope. So, you have 2/9, and then 9/2.
Answer:
slope of f = [tex]\frac{9}{2}[/tex]
Step-by-step explanation:
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{2}{9} }[/tex] = [tex]\frac{9}{2}[/tex]
What is included between two congruent sides in an isoceles triangle
In an isosceles triangle that has exactly two equal sides, the equal sides are called legs and the third side is called the base. The angle included by the legs is called the vertex angle and the angles that have the base as one of their sides are called the base angles.

A tree measured 18 1/2 feet tall. Over the next 7 1/2 years, it grew to be 63 1/2 feet tall. During the 7 1/2years, what was the average yearly growth rate of the tree?
Step-by-step explanation:
first subtract how tall is was 7 1/2 years ago from hell with all it is now. 57 - 40.5 = 16.5 or 16 1/2 so and the seven and a half years the tree Grace 16.5 with 16 1/2 seats to get the average yearly growth for the 7 1/2 year. You have to divide 16 and 1/2 ft by 7 and 1/2 Tim Wiles it makes it much easier if you change the fractions to decimals

b. Factorize using middle term break 3d2 - 16dc – 12c2
Step-by-step explanation:
Given
3d² - 16dc - 12c²
Using middle term break
= 3d² - (18 - 2 )dc - 12c²
= 3d² - 18dc - 2dc - 12c²
= 3d( d - 6c) - 2c( d - 6c)
= ( d - 6c) ( 3d - 2c)
Hope it helps and have a great day onwards ❤
Answer:
= 3d² - (18 - 2 )dc - 12c²
= 3d² - 18dc - 2dc - 12c²
= 3d( d - 6c) - 2c( d - 6c)
= ( d - 6c) ( 3d - 2c)

How much should Mr.Ajay and his wife save ina month to achieve their financial goal?
Answer:
RM 1000
Step-by-step explanation:
Down payment = 10% of 600 000
[tex]= \frac{10}{100}*600000[/tex]
= RM 60000
5 years = 5 * 12 = 60 months
Amount to be saved in a month = 60000 ÷ 60
= RM 1000
The vertex of a parabola is (3,-2) and another point on the parabola is (2,3) find the equation of the parabola in vertex form
Answer:
[tex]y = 5 ( x - 3 ) ^2 -2[/tex]
OR
[tex]y+2= 5 ( x - 3 ) ^2[/tex]
Step-by-step explanation:
Vertex form of a parabola is given as:
[tex]y = a ( x - h ) ^2 + k[/tex]
Where ([tex]h,k[/tex]) is the vertex and [tex](x,y)[/tex] are the points on the parabola.
We are given that, the vertex is (3, -2) and another point on parabola is given as (2, 3).
[tex]h = 3,k = -2[/tex]
First of all, putting the vertex in the vertex equation as given above:
[tex]y = a ( x - 3 ) ^2 + (-2)[/tex]
Now, putting the values of [tex]x, y[/tex] as 2, 3 and let us find the unknown variable [tex]a[/tex]:
[tex]3 = a ( 2 - 3 ) ^2 + (-2)\\\Rightarrow 3 = a -2\\\Rightarrow a = 5[/tex]
Therefore, the equation in vertex form can be written as:
[tex]y = 5 ( x - 3 ) ^2 -2[/tex]
OR
[tex]y+2= 5 ( x - 3 ) ^2[/tex]

Which of the following numbers has the same absolute value as 86?
A.-86
B.0
C.-172
D.-43
Answer:
A. -86
Step-by-step explanation:
The absolute value is the distance a number has from zero.
Two numbers that are the same, except that one is positive and negative, will have the same absolute value.
So, -86 and 86 have the same absolute value of 86. This is because they are both 86 away from 0.
So, A is the correct answer.
You are the president of an interior design company. You pay a part-time designer
$200 per week, plus $25 for each completed design. Write an equation to represent this
situation. Use this equation to determine how many completed designs you can have per
week if your weekly design budget is $800?
Answer: 24
Step-by-step explanation:
Okay, so if the part-time designer gets 200 dollars per week, we should subtract 200 by 800.
800 - 200 = 600.
Then we divide 600 by 25, and that will be the amount of completed designs we'll be able to have each week.
600 ÷ 25 = 24.
So in conclusion, you can pay the designer $200 per week and get 24 completed designs from him.
Hope this helps!

Answer:
1. 120
2. 26
3. 145
4. 95
5. 129
6. 98
Step-by-step explanation:
Number 1:
Remember: Diagonals are congruent (in this case scenario).
Remember: Consecutive angles are supplementary.
☆You are going to subtract 60 from 18p. (You are subtracting it from 180 specifically because the angles are on a straight angle, and a straight angle equals 180 degrees.)
[tex]180 - 60 = 120[/tex]
^Hence your answer^
Number 2:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 154 from 180.
[tex]180 - 154 = 26[/tex]
Number 3:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 35 from 180.
[tex]180 - 35 = 145[/tex]
Number 4:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 85 from 180.
[tex]180 - 85 = 95[/tex]
Number 5:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 51 from 180.
[tex]180 - 51 = 129[/tex]
Number 6:
Remember: Consecutive angles are supplementary.
☆You are going to subtract 82 from 180.
[tex]180 - 82 = 98[/tex]
ted's company has recieved an order to print 10^6 pages. ted's company has 100 machines , each of which can print 10^4 pages a day. ted's company can print the 10^6 pages in blank.
in exponent form, this number of days can be represented as blank
Answer:
1 day ; 10^0
Step-by-step explanation:
Given that:
Order received = 10^6 pages
Number of machines = 100
Daily printing capability by each machine = 10^4
Hence, total output per day = (10^4) * 100 = 10^4 * 10^2 = 10^4+2 = 10^6
Number of days required = number of order / daily output
Number of days = 10^6 / 10^6 = 1
In exponent form:
10^6 / 10^6 = 10^6-6 = 10^0
