Can someone please help me with this ty!!

Answer:

(-8, 2)

Step-by-step explanation:

1. Set up the equations.

y = 1/2x + 6

y = -3/4x - 4

2. Set the equations to equal each other.

1/2x + 6 = -3/4x - 4

3. Move the variables to one side and the numbers to the opposite side.

6 + 4 = -3/4x - 1/2x

10 = -3/4x - 2/4x

10 = -5/4x

4. Divide 10 by -5/4.

10/ -5/4 = 10 * -4/5 (when dividing fractions, flip the fraction over)

10 * -4/5 = -40/5 = -8

x = -8

5. Plug in the x-value into one of the equations.

y = 1/2x + 6

y = 1/2(-8) + 6

y = -4 + 6

y = 2

OR

y = -3/4x - 4

y = -3/4(-8) - 4

y = 6 - 4

y = 2

Answer:

  (a)  169.1 m

Step-by-step explanation:

The diagram shows you the distance (x) will be shorter than 170 m, but almost that length. The only reasonable answer choice is ...

  169.1 m

__

The relevant trig relation is ...

  Cos = Adjacent/Hypotenuse

The leg of the right triangle adjacent to the marked angle is x, and the hypotenuse is 170 m. Putting these values into the equation, you have ...

  cos(6°) = x/(170 m)

  x = (170 m)cos(6°) ≈ (170 m)(0.994522) ≈ 169.069 m

The horizontal distance covered is about 169.1 meters.

The number of cookies in the bag is A = 60

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 equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Now , 30 % of the cookies in the bag = 18 cookies

On simplifying the equation , we get

( 30 / 100 )A = 18

Multiply by 100 on both sides , we get

30A = 1800

Divide by 30 on both sides , we get

A = 1800/30

A = 60 cookies

Hence , the number of cookies is 60

Answer: D

Step-by-step explanation:

Answer:

Step-by-step explanation:

[tex]\boxed{\text{Area of triangular prism = length*(a+b+c) + 2*base area}}[/tex]

Here a, b,c are the sides of the triangle.

a = 14 cm ; b = c = 25 cm  and length = 10 cm

[tex]\boxed{\text{Base area=2*$\dfrac{1}{2}*base*height$=base *height}}[/tex]

base = a = 14 cm & h = 24 cm

Base area = 14*24

               = 336 cm²

Total surface area = 10*(14+25+25) + 336

                              = 10*64 + 336

                             = 640 + 336

                             = 976 cm²

Answer:

First we have to same the bases.

As we know 8=2^3.

Replace 8 with 2^3.

Like this .

2^3x=2^3(2x+1).

Now 3x=3(2x+1) distribute 3 by the Barker.

3x=6x+3.

6x+3=3x.

6x-3x=-3.

3x=-3.

X=-1.

Step-by-step explanation:

It is Given that 2x + 1 : x + 2 = x+8 : 3x-4 therefore, the possible value of x is -1.

An equation usually consists of equality of two mathematical expressions. Let it be

A = B

. If we take them to be equal to third variable, then:

A = B = C

type of equation is obtained.

We can then take it as a system of two equations as:

A = C\\ B=C

The solution to this system will give us the solution to the considered equation.

The solution to an equation is finding values of the variable included in the considered equation for which the equation considered evaluates to be true.

Answer:

The number with an absolute value (distance away from zero on a number line) that is greater than 5 will be: A. -6.

Absolute value of any number is simply the distance of that number from point zero (0) on a number line.

Thus,

-6 is 6 units from 0.

6 is also 6 units away from 0.

-5 is 5 units from 0.

5 is also 5 units from 0.

The absolute value of -5 is 5.

The absolute value of -6 is 6.

Therefore, the number with an absolute value (distance away from zero on a number line) that is greater than 5 will be: A. -6.
