Answer:
[tex]\left[\begin{array}{ccc}1&1&1|-1\\0&5&7|1\\0&-1&1|4\end{array}\right][/tex]
Step-by-step explanation:
The first operation:
[tex]2R_1 + R_2 ->R_2[/tex]
This means that the new second row (R2) is derived by:
Multiplying the first row (R1) by 2; add this to the second row
The row 1 elements are:
[tex]\left[\begin{array}{ccc}1&1&1|-1\end{array}\right][/tex]
Multiply by 2
[tex]2 * \left[\begin{array}{ccc}1&1&1|-1\end{array}\right] = \left[\begin{array}{ccc}2&2&2|-2\end{array}\right][/tex]
Add to row 2 elements are: [tex]\left[\begin{array}{ccc}-2&3&5|3\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}2&2&2|-2\end{array}\right] + \left[\begin{array}{ccc}-2&3&5|3\end{array}\right][/tex]
[tex]\left[\begin{array}{ccc}0&5&7|1\end{array}\right][/tex]
The second operation:
[tex]-3R_1 +R_3 ->R_3[/tex]
This means that the new third row (R3) is derived by:
Multiplying the first row (R1) by -3; add this to the third row
The row 1 elements are:
[tex]\left[\begin{array}{ccc}1&1&1|-1\end{array}\right][/tex]
Multiply by -3
[tex]-3 * \left[\begin{array}{ccc}1&1&1|-1\end{array}\right] = \left[\begin{array}{ccc}-3&-3&-3|3\end{array}\right][/tex]
Add to row 2 elements are: [tex]\left[\begin{array}{ccc}3&2&4|1\end{array}\right][/tex]

Isabella and Angel are reading the same book. At the beginning of the month, Isabella was on page 35 and Angel was on page 5. Isabella will read 10 pages per day and Angel will read 20 pages per day. Let I represent the page of the book that Isabella is on at the end of t days into the month, and let A represent the page of the book that Angel is on at the end of t days into the month. Graph each function and determine after how many days, t, Isabella and Angel will be on the same page of the book.
Answer:
3 days
Step-by-step explanation: (See Annex)
According to the problem statement, both readings (Isabela and Angel) are models for a straight line:
10 and 20 are the slopes of I and A respectively
I = 35 + 10*t
A = 5 + 20*t
The common point of the two lines will be the day when they both will be on the same page ( see annex)
then:
35 + 10*t = 5 +20*t
35 - 5 = 20*t - 10*t
10*t = 30
t = 3
Find the slope of the line.

Answer:
C. 1/4
Step-by-step explanation:
Line pass A(-2,-1) and B(2,0)
slope = Δy/Δx = (0 - (-1)) / (2 - (-2)) = 1/4
Answer:
the answer is C
Step-by-step explanation:
slope formula:
[tex] \frac{y2 - y1}{x2 - x1} [/tex]
(1) take two coordinates from the graph
i/ (2,0)
x1 = 2
y1 = 0
ii/ (6,1)
x2 = 6
y2 = 1
(2) substitute the values into the formula
[tex] \frac{1 - 0}{6 - 2} [/tex]
[tex] \frac{1}{4} [/tex]
The equation for line passing through (6, 3) and (4, 1) could be written in slope-intercept form as 
Answer:
[tex]\boxed {\boxed {\sf E. \ y=x-3}}[/tex]
Step-by-step explanation:
To find the equation of the line, we must first find the slope, then use the point-slope formula.
1. Find the Slope
The slope formula is the change in y over the change in x, or:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Where (x₁, y₁) and (x₂, y₂) are the points the line passes through.
The points given in the problem are (6,3) and (4,1). Therefore:
[tex]x_1=6 \\y_1=3 \\x_2=4 \\y_2=1[/tex]
Substitute the values into the formula.
[tex]m=\frac{1-3}{4-6}[/tex]
Solve the numerator.
1-3= -2[tex]m=\frac{-2}{4-6}[/tex]
Solve the denominator.
4-6=-2[tex]m=\frac{-2}{-2}[/tex]
Divide.
[tex]m=1[/tex]
2. Find the Equation of the Line
We have the slope and a point, so we can use the point-slope formula.
[tex]y-y_1=m(x-x_1)[/tex]
We know the slope is 1 and we can pick either point to use for (x₁, y₁). Let's use (4,1).
[tex]y-1=1(x-4)[/tex]
Distribute the 1.
[tex]y-1=(1*x)+(1*-4)\\y-1=x-4[/tex]
We want to find the equation in y=mx+b, so we must isolate the variable on one side of the equation.
1 is being subtracted from y and the inverse of subtraction is addition. Add 1 to both sides of the equation.
[tex]y-1+1=x-4+1\\y=x-4+1\\y=x-3[/tex]
In slope-intercept form, the equation of the line is y=x-3

Answer:
1). Area = 37 cm²
2). Area = 120 cm²
Step-by-step explanation:
Figures in the picture attached are the examples of composite figures.
1). Area of the composite figure = Area of rectangle A + Area of rectangle B
Since area of rectangle = Length × width
Area of rectangle A = 8 × 2 = 16 cm²
Area of rectangle B = 3 × 7 = 21 cm²
Area of the composite figure = 16 + 21 = 37 cm²
2). Area of the composite figure = Area of C + Area of D
= (3×4) + (9×12)
= 12 + 108
= 120 cm²
for the figure shown below, find the value of the variable and the measures of the angles.
x=
measure of angle P=
measure of angle Q=
measure of angle R=
Answer:
p=58
q=84
r=38
Step-by-step explanation:
x+46+2x-18+x=180 degree ( angle sum property )
4x + 28 = 180 degree
4x = 180 - 28
4x = 152
x = 152 /4
x= 38
angle p = 2x -18 = 2 *38 -18 = 58 degree
angle q = x + 46 = 38 +46= 84 degree
angle r = x = 38 degree
Answer:
x= 38°
measure of angle P= 58°
measure of angle Q= 84°
measure of angle R=38°
Step-by-step explanation:
Equations
The sum of the internal angles of a triangle is 180°. We are given the three angles as a function of x, thus:
2x - 18 + x + 46 + x = 180
Simplifying:
4x + 28 = 180
Subtracting 28:
4x = 180 - 28 = 152
x = 152/4 = 38
x = 38°
Angle P=2x-18=2*38-18=58°
Angle Q=x+46=38+46=84°
Angle R=x=38°

solve the equation: the booster club of the baseball team bought pizza to sell at a concession stand. the school donated three pies to the sale. each pie was then cut into 8 pieces and sold . there were a total of 64 pieces to sell. how many pies did the booster club purchase
Answer:
they bought 5 pies
Step-by-step explanation:
.................
Five pies were bought by the booster club of the baseball team.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
Three pies were provided for sale by the school. After that, each pie was divided into 8 pieces and sold. 64 pieces in all were available for purchase.
Let "p" be the number of pies the booster club purchased.
The school donated 3 pies, so the booster club purchased a total of p + 3 pies.
Each pie was cut into 8 pieces, so there were a total of (p + 3) × 8 = 64 pieces to sell.
This equation can be simplified to p + 3 = 8, or p = 5.
Therefore, there was a booster club that purchased 5 pies.

The measures of the angles of a triangle are shown in the figure below. Solve for x
75°
63°
Answer:
x = 20
Step-by-step explanation:
The sum of angle of a triangle is 180. Taking the sum of the angles and equating to 180 will give:
75 + 63 + 4x+2 = 180
138+2+4x = 180
140+2x = 180
2x = 180=140
2x = 40
x = 20
Hence the value of x is 20

You are making a 2 ingredient trail mix with almonds and raisins. There is a 5:7 ratio of almonds to raisins. How many ounces of almonds would be in a 3-pound bag of this trail mix? (There are 16 ounces in 1 pound.) *
Answer:
There would be 20 ounces of almonds in the bag
Step-by-step explanation:
System of Equations
To solve the problem, we'll set up these two variables:
x = ounces of almonds
y = ounces of raisins
The ratio of almonds to raisins in the trail mix is 5:7, thus:
[tex]\displaystyle \frac{x}{y}=\frac{5}{7}[/tex]
Cross-multiplying:
7x=5y [1]
A 3-pound bag of this trail mix contains 3*16=48 ounces that include almonds and raisins, thus:
x + y = 48 [2]
Multiplying [2] by 5:
5x + 5y = 240
Substituting from [1]:
5x + 7x = 240
12x = 240
x = 240/12
x = 20
There would be 20 ounces of almonds in the bag
solve for y please refer to image

What is the surface area of the right cone below?
Answer:
B. 68pi
Step-by-step explanation:
to find the surface area of a right cone given radius and slant height:
let A = surface area
let r = radius
let l = slant height.
A=pi*r*l + pi* r^2
plug in the values
A=pi*52+pi*16= about 213.62
The surface area of the cone is 68π sq. units.
What is surface area?The surface area of a figure is the number of unit squares it takes to cover the entire surface without gaps or overlaps. If a three-dimensional figure has flat sides, the sides are called faces. The surface area is the total of the areas of the faces.
Given that, the slant height and the radius of a cone is 13 units and 4 units respectively,
We need to find the surface area of the cone,
SA = π×r×l + π×r²
SA = π(4×13+16)
SA = 68π
Hence, the surface area of the cone is 68π sq. units.
