HELP ME PLZZZ ASAP!

Simplify the expression 6 − 2x + 5 + 4x.

Answer:

[tex]x + \frac{7}{2} = - 1 \\ x = - 1 - \frac{7}{2} \\ x = \frac{ - 2 - 7}{2} \\ x = \frac{ - 9}{2} \\ [/tex]

I hope this help you

Answer:

[tex]x = - \frac{9}{2} [/tex]

Step-by-step explanation:

(1. Subtract 7/2 From Both Sides

[tex]x = - 1 - \frac{7}{2} [/tex]

(2. Simplify -1 - [tex]\frac{7}{2} to - \frac{9}{2} [/tex]

[tex]x = - \frac{9}{2} [/tex]

Decimal Form: -4.5

Answer:

34

Step-by-step explanation:

*A triangle has an interior angle of 180 degrees

We know that one of the angle is 112 degree

180 - 112 = 68 degrees

We also know that the triangle is an isosceles triangle which means both sides and both angles are the same ( we can determine that it's an isosceles because of the two lines)

68 / 2 = 34

R = 34 degrees

T = 34 degrees

S = 112 degrees

okay don't feel bad, you actually got it right, let me help you with some holes!

You calculate slope by the rise over run. These people are confusing you a bit - do problem 2 then 1

the vertical change is -1 horizontal change is 3 so by rise/run=-1/3

-1/3 is the slope

for the second problem this is confusing but just read and try to analyze

vertical change/horizontal change = 5-4/0-3= 1/-3(or -1/3)

The y intercept is the point where the line hits the y axis, so at point (0, 5)

The function is y=mx+b

m is the slope

b is the y intercept

so y=-1/3x+5

Answer:a)24minutes b)12 minutes c)9.6minutes d)4.8 minutes

Step-by-step explanation:

x         50               x           25                      x                20              x         10

x(100)=48(50)          x(100)=48(25)                x(100)=48(20)            x(100)=48(10)

100x=2400                100x=1200                  100x=960                 100x=480

x=24minutesat50% x=12minutesat25%x=9.6minutesat20% x=4.8minutesat10%

In order to get slope-intercept form, we have to get the y alone. So we have to add 5x to both sides.

y-5x=10+x

y=10+x+5x

Now simplify.

y=10+6x

We need to switch the 10 and 6x around.

So the answer is y=6x+10

Step-by-step explanation:

So you know a point and the slope, now you can substitute the values of the point for the equation.

Answer: y = (5/2)x + 7

Step-by-step explanation:

Plug in given numbers into the following equation:

y = mx + b

Solve for b:

-3 = (5/2)(-2) + b

-3 = -10 + b

b = 7

Answer:

[tex]f(x) = \frac{24}{25} * \frac{5}{6}^x[/tex]

Step-by-step explanation:

Given

[tex](x_1,y_1) = (2,\frac{2}{3})[/tex]

[tex](x_2,y_2) = (3,\frac{5}{9})[/tex]

Required

Write the equation of the function [tex]f(x) = ab^x[/tex]

Express the function as:

[tex]y = ab^x[/tex]

In: [tex](x_1,y_1) = (2,\frac{2}{3})[/tex]

[tex]y = ab^x[/tex]

[tex]\frac{2}{3} = a * b^2[/tex] --- (1)

In [tex](x_2,y_2) = (3,\frac{5}{9})[/tex]

[tex]y = ab^x[/tex]

[tex]\frac{5}{9} = a * b^3[/tex] --- (2)

Divide (2) by (1)

[tex]\frac{5}{9}/\frac{2}{3} = \frac{a*b^3}{a*b^2}[/tex]

[tex]\frac{5}{9}/\frac{2}{3} = b[/tex]

[tex]\frac{5}{9}*\frac{3}{2} = b[/tex]

[tex]\frac{5}{3}*\frac{1}{2} = b[/tex]

[tex]\frac{5}{6} = b[/tex]

[tex]b = \frac{5}{6}[/tex]

Substitute 5/6 for b in (1)

[tex]\frac{2}{3} = a * b^2[/tex]

[tex]\frac{2}{3} = a * \frac{5}{6}^2[/tex]

[tex]\frac{2}{3} = a * \frac{25}{36}[/tex]

[tex]a = \frac{2}{3} * \frac{36}{25}[/tex]

[tex]a = \frac{2}{1} * \frac{12}{25}[/tex]

[tex]a = \frac{24}{25}[/tex]

The function: [tex]f(x) = ab^x[/tex]

[tex]f(x) = \frac{24}{25} * \frac{5}{6}^x[/tex]

Answer:

Step-by-step explanation:

Given question is incomplete; here is the complete question,

"Which system of equations has a solution of approximately (0.7, -1.4)?"

A). x - y = 2 and x + 2y = -2

B). x - 2y = -2 and x + y = 2

C). x - y = 2 and x - 2y = -2

D). x + y = 2 and x + 2y = -2

"If the given point (0.7, -1.4) is the solution of the system of equations, it will satisfy both the equations"

To check whether the statement given above is true or false we will substitute the values of x and y in the given equations,

A). x - y = 2

   0.7 - (-1.4) = 2.1

                    ≈ 2

    x + 2y = -2

   0.7 + 2(-1.4) = -2.1

                       ≈ -2

   True.

B). x - 2y = -2

     0.7 - 2(-1.4) = 3.5

    x + y = 2

    0.7 - 1.4 = -0.7

    False.

C). x - y = 2

    0.7 - (-1.4) = 2.1 ≈ 2

    x - 2y = -2

    0.7 - 2(-1.4) = 3.5

    False.

D). x + y = 2

    0.7 - 1.4 = -0.7

    x + 2y = -2

    0.7 + 2(1.4) = 3.5

    False.

Answer:

Your answer is A, or -200.

Since your slope is going down, you know that the number is going to be a negative value. Then, check where the line hits a direct point. You would notice that it hits every 200 number values, which means that your answer is A.

Answer:
