Factor by grouping

The second graph represents the situation y=1.25x which has slope 1.25.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

The given equation is y= 1.25x

Slope is 1.25

Now let us plug in (1, 1.25) in the equation

1.25=1.25(1)

Hence, the second graph represents the situation y=1.25x which has slope 1.25.

Answer:

x + 37 = 90

Step-by-step explanation:

Since complementary angles add up to 90 degrees, we would need to add 37 and x to equal 90 degrees. Therefore, x + 37 equals 90 degrees. As for solving, subtract 37 from both sides and you are left with x = 53.

there are 10  different combinations of pairs of colors.

Combinations are ways to choose elements from a collection in mathematics where the order of the selection is irrelevant. Let's say we have a trio of numbers: P, Q, and R. Then, combination determines how many ways we can choose two numbers from each group.

Given, Loris has one of each of the following colors of felt-tip pen in her pencil case: red (R) blue (B) yellow (Y) green (G) purple (P) She pulls out two random pens.

from the formula of combination;

total combination  ⁿCₓ = [tex]\frac{n!}{(n-r)! * r!}[/tex]

Where, n = total numbers

r = desired number out of total

In our case

n = 5 and r = 2

Thus, the Total combination = ⁵C₂

Total combination = 5! / (3! *2!)

total combination = 5 *4 /2 = 10

therefore, There are ten distinct ways to pair the colors together.

Step-by-step explanation:

Blake bought a new car. He borrowed $12,500 from the bank. After 4 years he had paid off the loan and paid $1500 in interest. What rate did he borrow at?

This is a simple interest question

The formula to find the rate is given as:

Equation:

r = (1/t)(A/P - 1)

t = time = 4 years

P = Principal = $12500

I = Simple Interest = $1500

A = Total Amount = Principal + Simple Interest = $12500 + $1500

= $14000

Calculation:

Solving our equation:

r = (1/4)((14000/12500) - 1) = 0.03

r = 0.03

Converting r decimal to R a percentage

R = 0.03 * 100 = 3%/year

1. The mapping of the vertices of ΔDEF will be;

2. The rule of the reflection across the line y = x is;

[tex]r_{x} = _{y} (x , y)[/tex] → [tex]r_{y} = _{x} (y , x)[/tex]

What is Refection?

Reflection is a type of transformation that flip a shape in mirror line, so that each point is the same distance from the mirror line as its reflected point.

Given that;

The coordinates are,

D = (2, –4)

E = (1, –1)

F = (5, 1)

Now,

By the given image,

The mapping of the vertices of ΔDEF is;

D(2, –4) → D' (-4, 2)

E(1, –1) → E' (-1 , 1)

F(5, 1) → F' (1, 5)

And, The rule of the reflection across the line y = x is;

[tex]r_{x} = _{y} (x , y)[/tex] → [tex]r_{y} = _{x} (y , x)[/tex]

Because in the image its shows the line of reflection.

Therefore,

1. The mapping of the vertices of ΔDEF will be;

D(2, –4) → D' (-4, 2)

E(1, –1) → E' (-1 , 1)

F(5, 1) → F' (1, 5)

The triangles ABC and SDC are similar triangles

From the question, we understand points S, C and A are collinear, while line AB and SD are vertical and parallel lines at the either sides of point C.

Hence, Gilligan can conclude that triangles ABC and SDC are similar

To do this, we make use of the following equivalent ratio

[tex]SD : 130 = AB : 23[/tex]

Substitute 90 for AB

[tex]SD : 130 =90 : 23[/tex]

Express as fraction

[tex]\frac{SD}{130} =\frac{90}{ 23}[/tex]

Make SD the subject

[tex]SD =\frac{90}{ 23} * 130[/tex]

[tex]SD =509[/tex]

Hence, Gilligan can conclude that the distance of the ship from the shore is 509 ft

but can u help me What is the surface area of a square-based pyramid with a base length of 5 m and a slant height of 3 m?

Enter your answer in the box.

The missing measurement is 10 feet.

A three-dimensional shape is a pyramid. A pyramid's flat triangular faces unite at a common point known as the apex and have a polygonal base. The bases are joined to the peak to create a pyramid. The lateral face is a triangle face formed by the connection of each edge of the base to the apex.

To find the surface area of the pyramid, we can use the following formula,

A = (½)Pl + B.

Where P is the base perimeter, l is the slant height and B is the base area.

Here, the base is square-shaped.

Now, let the slant height be x.

A = (1/2)(4 × 6) (x) + (6)²

156 = 12x + 36

12x = 156 - 36

12x = 120

x = 10 feet.

Therefore, the required height is 10 feet.

Answer: The answer is C) J' (3,-1), K' (1,-4)

Step-by-step explanation: First, you need to find the location of J, which is located in Quadrant III. You go left 3, and go down 1, making the coordinates of J (-3,-1). Next, you need to find the location of K, which is also located in (-1, -4).

So, the question asks, "What are the coordinates of J' and K' after JK is reflected across the y-axis?"-- Well, first, which line is the x-axis, and which line is the y-axis?

The x-axis is the line that is horizontal(Across) while the y-axis is the line that is vertical( Up and Down).

So you bring J and Ks coordinated over the y-axis to Quadrant IV(4). You already know their original coordinates, so you place the as you would in the picture above, except that the line would be reflected.

1.) MOM   3.) HIT   5.) WAXY

Step-by-step explanation: i hope this helps :)

The words in which all letters have vertical symmetry are MOM, HIT, and WAXY so options (A),(C), and (E) are correct.

If two figures look an exact shape but their size could be small or big then both figures are called similar figures.

When anything has identical pieces facing one another or revolving around an axis, it is said to be symmetrical.

Vertical symmetry is the way by which a latter will completely coincide about a vertical axis.

For example word "A".

If we take a vertical axis in the mid of the word "A" then about this axis the whole word will coincide by left and right.

Thus, another words are M, O, T, Y, H, X.

The words containing the above letters are MOM, HIT, and WAXY.

Hence "The words in which all letters have vertical symmetry are MOM, HIT, and WAXY".
