7th unit 5 lesson 1​

Answer:

A

Step-by-step explanation:

Given endpoints (x₁, y₁ ) and (x₂, y₂ ) then the midpoint is

( [tex]\frac{x_{1}+x_{2} }{2}[/tex], [tex]\frac{y_{1}+y_{2} }{2}[/tex] )

Here (x₁, y₁ ) = Q(- 8, 6) and (x₂, y₂ ) = A(- 5, 3) , then

midpoint = ( [tex]\frac{-8-5}{2}[/tex], [tex]\frac{6+3}{2}[/tex] ) = ( [tex]\frac{-13}{2}[/tex], [tex]\frac{9}{2}[/tex] ) = (- 6.5, 4.5 ) → A

Answer:

x> -10

Step-by-step explanation:

in order to find what the value of X is you have to multiply the 5 of the denominator into the -6 which would make -30.

You would then divide by 3 in order to get x by itself and would get -30÷3= -10

therefore the answer should be greater than -10

Hope this helped :)

Answer:

x > -10

Step-by-step explanation:

[tex]\frac{3x}{5} > -6[/tex]

Multiply both sides by 5/3

[tex]\frac{5}{3} * \frac{3x}{5} > \frac{5}{3} *(-6)[/tex]

Reduce Everything

[tex]x > -5*2[/tex]

Multiply

x > -10

Answer:

a=-2 and b=10/3

Step-by-step explanation:

Given that [tex]2i-2+i-\frac{2i}{3}+i=a+bi[/tex].

[tex]\Rightarrow -2+2i+i-\frac{2i}{3}+i=a+bi \\\\\Rightarrow -2+(2+1-2/3+1)i=a+bi \\\\\Rightarrow -2+\frac{10}{3}i=a+bi[/tex]

On comparing the real and imaginary parts, we have

a=-2 and b=10/3.

Answer:

Step-by-step explanation:

First, find the slope using the two given points and the slope equation.

[tex]m=\frac{y2-y1}{x2-x1}=\frac{17-8}{19-10}=\frac{9}{9}=1[/tex]

We can enter [tex]m[/tex] into our slope-intercept form now.

[tex]y=mx+b\\y=1x+b\\y=x+b[/tex]

Now, plug in one of the given points to solve for b.

[tex]8=10+b\\b=-2[/tex]

So our final form is:

[tex]y=x-2[/tex]

Hope this helps!

The equation of the line passing through the points (10, 8) and (19, 17) is y = x - 2.

The general equation or the slope - intercept form of a straight line is -

y = mx + c

Where -

[m] is the slope of the line.

[c] is the y - intercept.

Given is a line such that points (10, 8) and (19, 17) lie on this line.

The given coordinates are (10, 8) and (19, 17).

First, we will find the slope of the line as follows -

m = (17 - 8)/(19 - 10)

m = 9/9

m = 1

So, the equation of the line will be -

y = x + c

Now, we will find the y - intercept. As the line pass through the point

(10, 8), we can write -

8 = 10 + c

c = 8 - 10

c = -2

So, the equation of the line will be y = x - 2.

Therefore, the equation of the line passing through the points (10, 8) and (19, 17) is y = x - 2.

Answer: a = 45°

Step-by-step explanation:

The measure of∠PSR is given: 90°

Given PS = RS, this is an isosceles triangle. so measure of ∠SPR, labeled "a" is equal to the measure of ∠SPR.  

The total of all angles in a triangle is 180. So subtract 90, then divide by 2.

180-90 = 90

90/2 = 45

a = 45°

If "b" is supposed to be the measure of ∠SRQ, that is 15°  The larger triangle is equilateral; all the angles are 60°. 60 - 45 = 15

Answer:

The midpoint of the line segment is located at (-4, 4).

Step-by-step explanation:

We're given the coordinate points of a line that can help us find the midpoint.

The midpoint formula for a line is written as:

[tex]\bullet \ \ \ \displaystyle\big(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\big)[/tex]

Additionally, we are given the coordinate points (5, -4) and (-13, 12). We can use these and label them with the (x, y) system so we can substitute them into the formula.

In math, a coordinate pair is written as (x, y). This is where cos = x and sin = y. If we are given two coordinate pairs, we can label them with the (x, y) system but also incorporating a subscript to distinguish the two x-values from each other as well as the y-values. We do this by turning the two x-values into x₁ and x₂ and the y-values follow the same protocol: y₁ and y₂.

Therefore, we can label our two coordinates:

(5, -4)

(-13, 12)

Now, we can place these values into the midpoint formula and simplify to find our midpoint.

Recall that the midpoint formula is:

[tex]\bullet \ \ \ \displaystyle\big(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\big)[/tex]

Therefore, let's substitute these values.

[tex]\displaystyle\big(\frac{x_1+x_2}{2}, \frac{y_1+y_2}{2}\big)\\\\\\\big(\frac{5 + (-13)}{2}, \frac{(-4)+12}{2}\big)\\\\\\\big(\frac{-8}{2}, \frac{8}{2}\big)\\\\\\\boxed{(-4, 4)}[/tex]

Therefore, the midpoint of the line segment is located at (-4, 4), which is Option A.

Answer: Great question! A midpoint is exactly what it sounds like; the point in the middle of two objects (in this case it's the middle of these two coordinates). Another way to think of the middle of something in math is by using the average. To find the midpoint of two points, we just find the average of the x-values and the average of the y-values:

(x1 + x2)/2 , (y1 + y2)/2)

(5 + -13) / 2 , (-4 + 12) / 2)

( -8 / 2 , 8 / 2)

(-4 , 4)

So the answer would be A)

(-4, 4)

Explanation:

let ( x,y) be the midpoint of the line segment, then x =  5+(-13) / 2 = -8/2 = -4 and y = -4+(12 ) / 2 = 8/2 = 4, the mid point is ( -4,4)

Answer:

Step-by-step explanation:

The percentage increase from x to 5x is given by the equation P = 400 %

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the percentage increase be P

Now , the equation will be

Let the original value be = A

The value of A = x

Now , the increased value = B

The value of B = 5x

And , the percentage increase is given by the equation ,

P = ( ( Increased value - Original value ) / Original value ) x 100 %

Substituting the values in the equation , we get

The percentage increase P = ( ( 5x - x ) / x ) × 100 %

The percentage increase P = ( 4x/x ) × 100 %

The percentage increase P = 4 x 100 %

The percentage increase P = 400 %

Therefore , the value of P is 400 %

Hence , The percentage increase from x to 5x is 400 %

Answer: Number of Men = 44;

Number of Women = 64

Step-by-step explanation:

Let the number of men be x

At a party there were 20 more women than men. This means the number of women = x + 20

Since the men paid Rs 30 each, the women Rs 20 each, and the total receipts 2600. This will be represented in an equation as:

(30 × x) + [20 × (x + 20)] = 2600

30x + 20x + 400 = 2600

30x + 20x = 2600 - 400

50x = 2200

x = 2200/50

x = 44

The number of men = 44

Number of women = 44 + 20 = 64
