Answer:

A= 45 degrees

Step-by-step explanation:

aight so basic info here: all triangles are equal to 180 degrees knowing this we gotta make equation

80+7x-4+8x-1=180

combine like terms

75+15x=180

15x= 105

x= 7

now plug it back in

2x + 2y = –2 and 3x – 2y = 12 what does x and y equal?

Answers

Answer:

(2,-3)

Step-by-step explanation:

by elemination

2x + 2y = –2

3x – 2y = 12

cross out the 2y and -2y because the cancle each other.

that leaves 2x= -2

and 3x = 12.

simply add/subtract. 2x+3x=5x

-2+12=10.

5x=10

x=2.

now for the y. we have x so all we have to do is plug.

take any equation. 2x + 2y = –2 and plug 2 into the x.

2(2)+ 2y = –2

4+2y= -2

-2-4= -6

2y=-6

y=-3.

put x and y into ordered pairs

(2,-3) and done.

easy peasy.

Answer:

x=2 y= -3

Step-by-step explanation:

2x+2y = -2

x+y = -1 (dividing both sides with 2

x+1 = -y

3x - 2y = 12

3x + (-y)(2) = 12

3x + (x+1)(2) = 12

3x+2x+2=12

5x+2=12

x=2

-y= 1+2

y= -3

One way to recognize a ___ is to look for a line that divides the original image into two congruent parts.
A. line of symmetry
B. point of symmetry
C. center of symmetry
D. plane of symmetry

Answers

a because the line of symmetry is where the two parts of the image will meet

The correct option to look for a line that divides the original image into two congruent parts is called; A. Line of Symmetry

What is a Line of Symmetry?

The line of symmetry is defined as the axis or imaginary line that passes through the center of the shape or object and divides it into identical halves.

Now, from the question we see that the line divides the original image into two congruent parts which is the definition of line of symmetry.

Which expression shows the quotient of two terms where one of the terms includes the coefficient of 8?

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete; So, I will solve generally

Required

Quotient of two terms where 1 has a coefficient of 8

The quotient (Q) of a and b can be represented as:

[tex]Q = \frac{a}{b}[/tex]

Where a and b are the terms

For a or b to have a coefficient of 8, then a or b must be

[tex]a\ or\ b = 8x[/tex]

Where x is the variable

So, the quotient can be expressed as any of:

[tex]Q = \frac{8x}{y}[/tex]

[tex]Q = \frac{z}{8i}[/tex]

[tex]Q = \frac{24b}{8c}[/tex]

As long as one of the terms has a coefficient of 8

solve the equation 243×=73, where × is the base of the number.

Answers

243x/243 = 73/243
x= 73/243
x= 0.300412

The value of × that satisfies the equation 243× = 73 is approximately 0.6691.

To solve the equation 243× = 73, where × represents the base of the number, we need to determine the value of × that satisfies the equation.

We can start by rewriting the equation as an exponential equation:

243ˣ= 73

To solve for ×, we need to isolate × on one side of the equation. We can do this by taking the logarithm of both sides of the equation. Let's take the logarithm with base 10 (log) for simplicity:

log(243ˣ) = log(73)

Applying the logarithmic property, we can bring down the exponent × as a multiplier:

× * log(243) = log(73)

Now, we can solve for × by dividing both sides of the equation by log(243):

× = log(73) / log(243)

× ≈ 0.6691

Therefore, the value of × that satisfies the equation 243× = 73 is approximately 0.6691.

Help me please!!:((((

Answers

Answer:

.01*.5ˣ

Step-by-step explanation:

we can see that x=0 y= .01

so in our equation

a*bˣ

a=.01

This is throuhg plugging in 0 for x

a*b⁰=.01

a*1=.01

a=.01

Now it's just a matter of finding b

to do this just plug in a value

we know that when x=1 y=.005

.01*b¹=.005

b= .5

So our final equation is : .01*.5ˣ
