7,000 divided by 70 is 100

I would use a calculator, but the answer is one hundred (100). If you have to show your work, what I do is I take my numerator and divide it by the denominator bit by bit. Write down 7,000, and then above that write down 70. In between the two draw a line. Like an upside down "l".

Write an equation (in slope-intercept form) of the line that passes through (0, 3) and (−5, 2.5).

Paladinen [302]

The equation of the line passing throught the points $A(x_A,y_A)$ and $B(x_B,y_B)$ has a form

$\dfrac{x-x_A}{x_B-x_A}=\dfrac{y-y_A}{y_B-y_A}.$

Now the equation of the line passing through points (0, 3) and (−5, 2.5) is

$\dfrac{x-0}{-5-0}=\dfrac{y-3}{2.5-3}.$

Simplify it:

$\dfrac{x}{-5}=\dfrac{y-3}{-0.5},\\ \\0.5x=5(y-3),\\ \\5x=50y-150,\\ \\x=10y-30,\\ \\10y=x+30,\\ \\y=0.1x+3.$

This equation is in slope-intercept form.

Answer: y=0.1x+3.

4. Solve the equation using the quadratic formula.

Vikentia [17]

Answer:

A. x = -2, x = 1.25

Step-by-step explanation:

<u>Use the </u><u>quadratic</u><u> formula</u>

x = $\frac{-b+\sqrt{b^{2}-4ac } }{2a}$

Once in standard form, <u>identify</u> a, b, and c from the <u>original</u> equation and plug them into the <u>quadratic formula</u>.

4x² + 3x - 10 = 0

a = 4

b = 3

c = - 10

x = $\frac{-3+\sqrt{3^{2}-4x4(-10) } }{2x4}$

<u>Simplify</u>

<u>Evaluate the exponent</u>

x = $\frac{-3+\sqrt{9-4x4(-10)} }{2x4}$

<u>Multiply</u> the numbers

x = $\frac{-3+\sqrt{9+160} }{2x4}$

Add the <u>numbers</u>

x = $\frac{-3+\sqrt{169} }{2x4}$

Evaluate the <u>square root</u>

x = $\frac{-3+13}{2x4}$

<u>Multiply</u> the numbers

x = $\frac{-3+13}{8}$

<u>Separate</u><u> the equations</u>

To solve for the <u>unknown variable</u>, separate into two equations: one with a plus and the other with a minus.

x = $\frac{-3+13}{8}$

x = $\frac{-3-13}{8}$

<u>Solve</u>

Rearrange and isolate the <u>variable</u> to find each <u>solution</u>

x = - 2

x = 1.25
