Answer:

A

Step-by-step explanation:

Area of a triangle:

A=\frac{b*h}{2}

In our case:

b=4

h=2

Plug in what we know:

A=\frac{(4)(2)}{2} \\A=4units

Find the matching solution:

A.) it is 1/2 the area of a rectangle of length 4 units and width 2 units

X B.) it is twice the area of a rectangle of length 4 units and width two units

X C.) it is 1/2 the area of a square of side length 4 units

X D.) it is twice the area of a square of side length 4 units

4m-3n=8; solve for m
Ierofanga [76]
4m - 3n = 8

Add 3n to both sides.

4m = 3n + 8

Divide both sides by 4.

m = 3/4n + 2

So, m = 3/4n + 2

However, if you made a typo, and meant 3m instead of 3n, your answer would be :

4m - 3n = 8

n = 8

Find the value of x.<br> X =
Paladinen [302]

Answer:

X = 20

Step-by-step explanation:

when you have an angle that looks like an X shape the angles opposite each other are always equal. knowing this we now know that angle 5x must equal 100

so just make X the subject of the formula and solve, like shown bellow

5x = 100

x = 100 \div 5

x = 20

Exponential Graphs. Can anyone help with this please? I don’t understand anything on this topic, so any explanation will help :)
Fed [463]

Answer:

The correct option is;

a > 1

Step-by-step explanation:

An exponential function can be expressed in the following general form;

f(x) = b·aˣ + k

Where;

b = The coefficient term

a = The base

x = The exponent

k = The vertical shift

The characteristic of an exponential function is that it increases if a > 1

From the graph, we have;

As 'x' increases to the right of the graph, f(x) = aˣ increases (upwards), therefore, a > 1

Solve the following system of equations.
Elan Coil [88]

Answer:

(2,-3)

Step-by-step explanation:

I am not sure if you meant the first equation to be y or -y.  I solved it as y.

y = x-5                       -x -3y =7

I am going to take the second equation and write it as x =

-x - 3y = 7  Give equation

-x = 3y +7   Add 3y to both sides

x = -3y-7  Multiplied each term in the equation by -1 so that x could be positive

I am going to substitute -3y-7 for x in the first equation up above

y = x - 5

y = -3y -7 - 5  Substitute -3y-7 for x

y = -3y -12  Combined -7-5

4y = -12  Added 3y to both sides

y = -3  Divided both sides by 4.

I now know that y is -3, I will plug that into x = -3y-7 to solve for x

x = -3(-3) -7

x = 9-7   A negative times a negative is a positive

x = 2
