Answer:

6x + 2 is your answer I THINK

Answer:

x=19

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

2x+7=3(x−4)

2x+7=3(x−4)

2x+7=(3)(x)+(3)(−4)(Distribute)

2x+7=3x+−12

2x+7=3x−12

Step 2: Subtract 3x from both sides.

2x+7−3x=3x−12−3x

−x+7=−12

Step 3: Subtract 7 from both sides.

−x+7−7=−12−7

−x=−19

x=19

Answer: your answer would be A

Step-by-step explanation:

When the product of the slopes of two lines is -1.

The lines are perpendicular.

When the product of the slopes of two lines is 1.

The lines are on the same line.

When the slopes of two lines are the same.

The lines are parallel.

slope of AB x slope of CD = 1

The lines are on the same line.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

A (3,5), B(−2,7), C(10,5), D(6,15).

When the product of the slopes of two lines is -1.

The lines are perpendicular.

When the product of the slopes of two lines is 1.

The lines are on the same line.

When the slopes of two lines are the same.

The lines are parallel.

The line AB.

Slope = (7 - 5) / (-2 - 3) = 2 / -5 = -2/5

The line CD.

Slope = (15 - 5) / (6 - 10) = 10 / -4 = -5/2

Now,

slope of AB x slope of CD.

= -2/5 x -5/2

= 1

This means,

The lines are on the same line.

Thus,

slope of AB x slope of CD = 1

The lines are on the same line.

Answer:

x=2.65

Step-by-step explanation:

First, we need to figure out how much the length of the sides is changing between the equations. In this case it is changing by a factor of 2.5. Now we need to work backwards. First use this equation:

[tex]4x-5*2.5=14[/tex]

This is because whatever the length of the side with x is, will be 14/2.5. So divide both sides by 2.5:

[tex]4x-5=5.6[/tex]

Next, add 5 to both sides:

[tex]4x=10.6[/tex]

Then divide both sides by 4:

[tex]x=2.65[/tex]

Step-by-step explanation:

point-slope equation of the line: y+1 = -(x-3)

rearrange to solve for y:

y+1 = -x+3

y = -x + 2   slope-intercept form

Answer:

y = -x + 2

Step-by-step explanation:

We are given that a line has a slope of -1 and passes through the point (3, -1)

We want to write the equation of this line in slope-intercept form

Slope-intercept form is written as y=mx+b, where m is the slope and b is the value of y at the y intercept

As we are already given the slope, we can immediately plug its value into y=mx+b.

Replace m with -1 in y=mx+b.

y = -x + b (there's no need to write -1 in front of x. If -1 is the coefficient in front of a variable, just writing a minus sign in front of the variable is enough).

Now we need to find b.

As the equation passes through the point (3, -1), we can use it to help solve for b.

Substitute 3 as x and -1 as y.

-1 = -3 + b
Add 3 to both sides

2 = b

Substitute 2 as b in the equation so far.

y = -x + 2

788 disc

Step-by-step explanation:

Let

x = number of months

Fry's Electronics;

= 920 - 12x

Blu-ray discs:

= 502 + 26x

Equate both equations

920 - 12x = 502 + 26x

920 - 502 = 26x + 12x

418 = 38x

x = 418/38

x = 11 months

number of months = 11

Substitute 11 into any of the equation

Fry's Electronics;

= 920 - 12x

= 920 - 12(11)

= 920 - 132

[tex] x = \sqrt 5[/tex]

Step-by-step explanation:

On solving by Pythagoras theorem:

(Going in counterclockwise direction)

For bottom most triangle :

Length of Hypotenuse [tex] = \sqrt {1^2 +1^2} =\sqrt {1+1}=\sqrt 2[/tex]

The for second triangle :

Length of Hypotenuse [tex] = \sqrt {(\sqrt 2) ^2 +1^2} =\sqrt {2+1}=\sqrt 3[/tex]

The for third triangle :

Length of Hypotenuse [tex] = \sqrt {(\sqrt 3) ^2 +1^2} =\sqrt {3+1}=\sqrt 4 = 2[/tex]

The for fourth triangle :

x [tex] = \sqrt {(2) ^2 +1^2} =\sqrt {4+1}=\sqrt 5 [/tex]

The x value for the given partial spiral is √5 units.

We need to solve for x in the partial spiral given.

The Pythagoras theorem which is also referred to as the Pythagorean theorem explains the relationship between the three sides of a right-angled triangle. According to the Pythagoras theorem, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a triangle.

From the right triangle 1:

Let the hypotenuse be a.

So, a²=1²+1²

⇒a=√2

From the right triangle 2:

Let the hypotenuse be b.

So, b²=(√2)²+1²

⇒b=√3

From the right triangle 3:

Let the hypotenuse be c.

So, c²=(√3)²+1²

⇒b=√4=2

From the right triangle 2:

The hypotenuse=x

So, x²=2²+1²

⇒x=√5

Therefore, the x value for the given partial spiral is √5 units.

Answer:

18.85 cm

Step-by-step explanation:

Answer:

2nd one is 4.48

Step-by-step explanation:

Given :

▪︎Measure of ∠G = 64°

▪︎△GAM is an isosceles triangle.

We know that :

▪︎The opposite base angles of an isosceles triangle are always equal.

Let the measure of ∠A be x.

Then, the measure of ∠M will also be x.

Which means :

[tex] = \tt64 + x + x = 180[/tex]

[tex] = \tt64 + 2x = 180[/tex]

[tex] = \tt2x = 180 - 64[/tex]

[tex] =\tt 2x = 116[/tex]

[tex] =\tt x = \frac{116}{2} [/tex]

[tex] = \tt \: x = 58[/tex]

Since the sum of all these angles is equivalent to 180°[64+58+58=180], we can conclude that we have found out the correct measure of each of these angles.

Measure of ∠A = 58°

Measure of ∠M = 58°

Step-by-step explanation:

The equation of the red graph is [tex]x^{2} +2[/tex].

The equation of the parabola whose vertex is (h, k) is

[tex]y = a(x-h)^{2} + k[/tex]

According to the given question.

We have a graph for the function f(x) and g(x).

[tex]f(x) =x^{2}[/tex]..(i)

⇒ the equation of parabola whose vertex is (0, 0)

Since, we know the standard form of the  equation of parabola is

[tex]y = a(x-h)^{2} +k[/tex]

Substitute h = 0 and k = 0 in the above equation.

⇒ [tex]y = a(x-0)^{2} +0[/tex]

⇒ [tex]y = ax^{2}[/tex]..(ii)                          (where, y = f(x))

On comparing the first two equations we get a = 1.

From the graph we can see that g(x) is a equation of parabola, whose vertex is (0, 2).

Therefore, the equation for red graph is given by

[tex]g(x) =a(x-0)^{2} + 2[/tex]

[tex]g(x) = 1x^{2} +2[/tex]                 (because a = 1)

⇒ [tex]g(x) = x^{2} +2[/tex]

Hence, option c is correct.

Answer:y=7(2)^x

Step-by-step explanation:

The exponential function in the form y=ab^x that goes through the given points is f(x) = 7(2)ˣ.

Exponential functions are functions where the independent variable, x is in the exponent.

The general form of exponential function is,

f(x) = abˣ

The function passes through (0,7) and (9, 3584).

Substituting (0, 7),

7 = a b⁰

7 = a  (since b⁰ = 1)

So, a = 7

Function is f(x) = 7bˣ

Now Substituting (9, 3584),

3584 = 7 b⁹

b⁹ = 3584 / 7

b⁹ = 512

b⁹ = 2⁹

b = 2

So the function is f(x) = 7(2)ˣ

Hence the function is f(x) = 7(2)ˣ.
