Answer:

4. 3169

5. 60

Step-by-step explanation:

4. To evaluate the value, you must substitute the variable with it’s given value.

12 - 3m +(8m)^2 = 12 - 3 x -7 + ( 8 x -7)^2 = 12 +21 + 3136 = 3169.

5. Let the number be y.

130/100 x y = 78

13y/10 = 78

13y = 780

y = 60.

Hope this helps

Solve the following system of equations by graphing and select the correct answer below:

JulijaS [17]

Answer: option c

Step-by-step explanation:

Find the x-intercept and y-intercept of each line.

To find the x-intercept, substitute $y=0$ into the equation and solve for "x".

To find the y-intercept, substitute $x=0$ into the equation and solve for "y".

- For the first equation:

x-intercept

$4x + 3y = 29\\\\4x + 3(0)= 29\\\\4x=29\\\\x=\frac{29}{4}\\\\x=7.25$

y-intercept

$4x + 3y = 29\\\\4(0) + 3y = 29\\\\3y=29\\\\y=\frac{29}{3}\\\\y=9.66$

Graph a line that passes through the points (7.25, 0) and (0, 9.66)

- For the second equation:

x-intercept

$2x - 3y = 1 \\\\2x - 3(0) = 1 \\\\2x=1\\\\x=0.5$

y-intercept

$2x - 3y = 1\\\\2(0) - 3y = 1\\\\-3y=1\\\\y=-0.33$

Graph a line that passes through the points (0.5, 0) and (0, -0.33)

Observe the graph attached. You can see that point of intersection of the lines is (5,3); then this is the solution of the system. Therefore:

$x=5\\y=3$

For each expression ,use the distributive property to write an equivalent expression

liq [111]

A. 4•x and 4•2 this would turn in 4x+8
B. x•6 and x•8 this would turn into 6x+8x and this equals to 14x
C. 4•2x and 4•3 this would turn into 8x+12.
D. 6•x, 6•y, and 6•z this would equal 6x+6y+6z.

I’m sorry if it’s not clear this is my first answered question.
