Step-by-step explanation:
Given equation of the line is,
y = 2x + 1
By comparing this equation with the slope-intercept form of the equation,
y = mx + b
m = Slope of the line = 2
b = y-intercept = 1
Table for the input - output values,
x -1 0 1 2
y -1 1 3 5
Now graph these points on the graph and join them by a straight line.

1. Sara bought cartons of raspberries that cost $1.50 and cartons of blackberries cost $2. Sara spent $11 buying raspberries and blackberries. She bought a total of 6 cartons. How many cartons of blackberries did she buy?
Answers
Sara brought a total of 5 cartons of blackberries. Since it said that Sara brought 6 cartons and you know that the cost of the blackberries are $2, you multiply 6 with 2 but its 12. But if Sara brought 2 cartons of raspberries it will be $3. Now you subtract 6 with 2 since you used 2 cartons on raspberries and now multiply $2 with 4 and get 8. 8+3=11, which is exactly how much she needs. This means that Sara brought 4 cartons of blackberries.

When will Mrs. Dual run
out of pencils?
Answers
Answer:
Part 1
The given information represented as a function, f(x) is;
f(x) = 150 - 10·x
Part 2
Please find attached the given information represented as a graph is created with Microsoft Excel
Part 3
Mrs. Dyal will run out of pencils after giving away pencils for 15 weeks
Step-by-step explanation:
The word problem relates to linear functions of the form f(x) = y = m·x + c
The given parameters are;
The number of pencils Mrs. Dyal has at the start of the year = 150 pencils
The number of pencils Mrs. Dyal gives away per week = 10 pencils
Part 1
Let "x" represent the number of weeks at which Mrs. Dyal is giving away the pencils
Given that she gives away 10 pencils each week, we have the function that represent the number of pencils remaining after "x" weeks is given as follows;
f(x) = 150 - 10×x.
The number of weeks, "x", that passes before Mrs. Dyal runs out of pencil (f(x) = 0) is given as follows;
f(x) = 0 = 150 - 10 × x
∴ 150 Pencils = 10 Pencils/Week × x
x = 150 Pencils/(10 Pencils/Week) = 15 Weeks
x = 15 Weeks
Therefore Mrs. Dyal will run out of Pencil at when x = 15 Weeks
Part 2
The function can be represented as a graph using the table of values as follows ;
Pencil remaining [tex]{}[/tex] Number of weeks
150 [tex]{}[/tex] 0
140 [tex]{}[/tex] 1
130 [tex]{}[/tex] 2

30 [tex]{}[/tex] 12
20 [tex]{}[/tex] 13
10 [tex]{}[/tex] 14
0 [tex]{}[/tex] 15
The domain = 0 ≤ x ≤ 15 {x ∈ N including 0}
The range = 0 ≤ f(x) ≤ 150
From the graph of the function created with Microsoft Excel, Mrs Dyal has no more Pencils left when x = 15 weeks

Answers
Answer:
C) 5
Step-by-step explanation:
The measure of angle TSU is 75°. (180° - 105° because it is a flat angle)
The sum of all the angles of a triangle is 180° as well.
You can write an equation to solve for x.
12x + 9x + 75 = 180
Isolate x.
12x + 9x = 180 - 75
12x + 9x = 105
Add the 12 and the 9.
21x = 105
Find what x is.
x = 105 ÷ 21

Gerardo divides 1/2 by 2, and then divides the quotient by 2 again. Draw a circle to represent one whole. Then use it to explain how Gerardo's work is similar to dividing 1/2 by 4.
Answers
Answer:
Kindly check attached picture for circle illustration.
Step-by-step explanation:
The whole circle = 1
Half the circle = semicircle = 1/2
Half the semicircle = 1/4
Half of 1/4 = 1/8
Hence, Geraldo would obtain 1/8
Normal calculation:
1/2 ÷ 2
1/2 * 2/1 = 1/4
Quotient = 1/4
Quotient / 2
1/4 ÷ 2
1/4 * 1/2
= 1/ 8

Par quelle fraction est multipliée l'aire d'un rectangle si l'on augmente sa longueur de son cinquième et sa largeur de son tiers ?
Answers
Répondre:
8/15
Explication étape par étape:
Prendre:
Longueur = x
Largeur = y
Zone du rectangle = Longueur * largeur
Un cinquième de longueur = x / 5
Un tiers de largeur = x / 3
Zone d'origine = xy
Nouvelle dimension:
Longueur = x + x / 5 = (5x + x) / 5 = 6x / 5
Largeur = x + x / 3 = (3y + y) / 3 = 4y / 3
Nouvelle zone = 6x / 5 * 4y / 3
Nouvelle zone = (24/15) xy
Fraction de la nouvelle zone par rapport à la zone d'origine:
(24/15) xy: xy
24/15: 1

Write an algebraic expression for the verbal expression: three times the sum of X and Y increase by five times the product of x and 3y.
Answers
Answer:
3(x+y)+15xy
Step-by-step explanation:
Write an algebraic expression for the verbal expression: three times the sum of X and Y increase by five times the product of x and 3y.
Sum of x and y = x+y
three times the sum of X and Y = 3(x+y)
product of x and 3y = x(3y) = 3xy
five times the product of x and 3y = 5(3xy) = 15xy
Three times the sum of X and Y increase by five times the product of x and 3y will be expressed as;
3(x+y) + 15xy
Hence the required algebraic expression is 3(x+y)+15xy

What is the equation, in standard form, of a parabola that models the values in the table?
x= -2, 0, 4
f(x)= 2.5, 1.5, -60.5
Answers
Answer:
y=-2.5[tex]x^{2}[/tex]+4.5x+1.5
Step-by-step explanation:
standard form of equation of parabola is,
y=a[tex]x^{2}[/tex]+bx+c
For x=0
1.5=0a+0b+c
1.5=c
For x=-2,
2.5=4a-2b+c
substituting the value of c
2.5=4a-2b+1.5
on solving,
4a-2b=1____________(1)
For x=4,
-60.5=16a+4b+c
substituting the value of c,
-60.5=16a+4b+1.5
on solving,
16a+4b=-62_______(2)
Multiplying equation 1 by 2,
8a-4b=2_______(3)
adding equation 2 and 3
16a+4b+8a-4b=-62+2
24a=-60
on solving,
a=-2.5
substituting the value of a in equation 1,
10-2b=1
2b=9
b=4.5
hence, equation of parabola in standard form is,
y=-2.5[tex]x^{2}[/tex]+4.5x+1.5

Which function had the same y-intercept as the function y= 2/3 x-3
Answers
Answer:
y-intercept of the function [tex]y=\frac{2}{3}x-3[/tex] is -3.
Step-by-step explanation:
We need to find the function that had the same y-intercept as the function [tex]y=\frac{2}{3}x-3[/tex]
(Note: Since the options are not given, so I will find the y-intercept of the given equation and you can match it with the functions and find the y-intercept of the required function)
The equation given [tex]y=\frac{2}{3}x-3[/tex] is written in slope-intercept form i.e [tex]y=mx+b[/tex] where m is slope and b is y-intercept.
Comparing equation [tex]y=\frac{2}{3}x-3[/tex] with [tex]y=mx+b[/tex] we get the value of b = -3
So, y-intercept of the function [tex]y=\frac{2}{3}x-3[/tex] is -3.
Now, for the options (not included) in the question, you can find y-intercept and function that have y-intercept = -3 will be the answer.
