Solve for z 7-√3z+2=4 What is the root? If there is no root, choose none. z = 7/3 z = 11/3 none
cestrela7 [59]

Answer:

Desmos is Function Calculator is a great tool for this, the correct answer is z= 7/3

7/3= 2.333~ and so √(3*2.333~) + 2= 2.9999999833333~

Now 7- 2.9999999833333~= 4.0000000166667~ but I don't know the true infinate sign for this so thats why my numbers look a little weird, just plug (7/3) in for z and you will get 4, trust me

How can knowing the slope and y-intercept help you graph an equation?​
stealth61 [152]

Answer:

<h3><em>To graph the equation of a line, we plot at least two points whose coordinates satisfy the equation, and then connect the points with a line. We call these equations "linear" because the graph of these equations is a straight line.</em></h3><h3><em /></h3><h3><em>There are two important things that can help you graph an equation, slope and y-intercept.</em></h3><h3><em /></h3><h3><em>Slope</em></h3><h3><em>We're familiar with the word "slope" as it relates to mountains. Skiers and snowboarders refer to "hitting the slopes." On the coordinate plane, the steepness, or slant, of a line is called the slope. Slope is the ratio of the change in the y-value over the change in the x-value. Carpenters and builders call this ratio the "rise over the run." Using any two points on a line, you can calculate its slope using this formula.</em></h3>

a cube is 6.75 cm on each side. Using the formula volume = (length of a side)^3, and 1 inch = 2.54 cm, determine the volume of t
andriy [413]
The volume of a cube is then (6.75cm)^3. Here the units are cubic centimeters or cm^3. Since there are 2.54 cm in 1 inch [exact] and 12 inches in 1 foot, the volume of the cube is (6.75 cm)^3 * (1 inch/2.54cm)^3 * (1 ft/12 inch)^3. 0.01086 ft^3 is your answer
