Answer 1

Finding slope:

Take two pairs of cordinate points from the table and use the formula y2-y1 divided by x2-x1

I choose (4,3) and (2,2)

2-3 divided by 2-4

= -1/2

Then to get the y intercept you use the formula: y=mx+b

For the x and y pick a cordinate to plug in. For m plug in your slope.

I pick (6,4)

4=-1/2×6+b

Multiply -1/2 and 6 to get -3 and plug that in

4=-3+b

Now add 3 to the -3 canceling that out to 0 and add three to the 4 making that 7

7=b

Y-intercept =7

Now plug in the slope and y-intercept into the slope intercept format and get:

Y=-1/2x+7

Daniel has 6,174 pokemon cards:)

We know this because 18 x 343 is 6,174.

(Hope this helps)

Ava has a total of 116 cards ALL together because 18p+98c

So if we want to figure out how many cards Daniel has, you will do 343×18.

So that equals 6174, and if you want to divide it to be sure, 6174÷343 is 18.

So Daniel has 6174 cards, 343 times the amount of cards Ava has.

Tamar used the algebraic method to convert the repeating decimal number to 2.45 to a fraction. Her first two steps are shown below. Step 1: x=2.45. Step 2: 100x=245.45. What should be Tamar’s next step

Answers

Answer:

see explanation

Step-by-step explanation:

Given the 2 equations

x = 2.4545... → (1)

100x = 245.4545... → (2)

Subtract (1) from (2) eliminating the repeating decimal

99x = 243 ( divide both sides by 99 )

x = [tex]\frac{243}{99}[/tex]

Triangle S R Q is shown. Angle S R Q is a right angle. An altitude is drawn from point R to point T on side S Q to form a right angle. The length of S T is 9 and the length of T Q is 16. The length of R T is x. What is the value of x? 12 units 15 units 20 units 25 units

Answers

Answer:

RT = 12 units

Step-by-step explanation:

From the figure attached,

ΔSRQ is right triangle.

m∠R = 90°

An altitude has been constructed from point T to side SQ.

m∠RTQ = 90°

By applying geometric mean theorem in triangle SRQ,

[tex]\frac{\text{RT}}{\text{ST}}=\frac{\text{TQ}}{\text{RT}}[/tex]

[tex]\frac{x}{9}=\frac{16}{x}[/tex]

x² = 16 × 9

x² = 144

x = √144

x = 12

Therefore, length of altitude RT is 12 units.

Answer:

12 units

four times a number increased by one is between a negative seven and thirteen. Find all numbers.

Answers

Answer:

Step-by-step explanation:

Let the number be x.

four times the number:

4x

If the exprression is increased by 1, it will become:

4x+1

If the value is between -7 and 13, the value of x will be within the range [-6, 12]

Equating the resulting expression to each end point.

At end point of -6

4x+1 = -6

4x = -6-1

4x = -7

x = -7/4

At the end point of 12:

4x+1 = 12

4x = 12-1

4x = 11

x = 11/4

Hence all the numbers will be within the range [-7/4, 11/4] or -7/4≤x≤11/4

PQ = 3x + 14 and QR = 7x - 10; Find x.
Answer
3x+14=7x-10
14+10=7x-3x
24=4x
6=x

Answers

Answer:

6

Step-by-step explanation:

3x+14=7x-10

14+10=7x-3x

24=4x

6=x

please follow me...

The value of x in the expression is 6.

To obtain the value of x, we equate both PQ and QR

PQ = 3x + 14

PQ = 3x + 14 QR = 7x - 10

PQ = QR

(3x + 14) = (7x - 10)

3x + 14 = 7x - 10

Collect like terms

3x - 7x = - 10 - 14

-4x = - 24

Divide both sides by - 4

x = - 24 / -4

x = 6

Hence, the value of x = 6

What is Collinear lines?

Three or more points  are said to be collinear if they lie on a single straight line. A line on which points lie, especially if it is related to a geometric figure such as a triangle, is sometimes called an axis. Two points are trivially collinear since two points determine a line.

So, using the concept of collinear line and translation we have

A translation is a type of transformation that moves each point in a figure the same distance in the same direction.

So, the line is congruent.

What is a quadratic equation ?

Any equation of the form [tex]\rm ax^2+bx+c=0[/tex]  where x is variable and a, b, and c are any real numbers where a ≠ 0 is called a quadratic equation.

As we know, the formula for the roots of the quadratic equation is given by:

[tex]\rm x = \dfrac{-b \pm\sqrt{b^2-4ac}}{2a}[/tex]

Here:

Discriminant D:

[tex]\rm D =\sqrt{b^2-4ac}[/tex]

D = 0

[tex]\rm x = \dfrac{-b \pm0}{2a}[/tex]

x = -b/2a (one real solution)

Thus, it has one real solution if the discriminant of an equation is zero, option (A) is correct.

To find slope on the graph you use rise/run like #1 you go up 3 and across 2 so it’s 3/2 and positive because the line is going up if it were going going down it’s a negative slope…now to find it with the formula it says it right there y2-y1 over x2-x1 for example 14-10 over -7-8 and simplify if you can…on the table you will do the same as you did with the formula on #15 you will use the formula like this 2-5 over -2+3 because we all know when you subtract a negative with a negative you’re basically adding them together
