Answer:
Use the graphing tool to graph the linear equation.
Step-by-step explanation:
To subtract fractions, we need an lcd( lowest common denominator)
8. the lcd is 42 because it’s the smallest number that 6 and 7 are both factors of. the lcd is the bottom of the fraction
to make the denominator of (4/7) 42, we will multiply the top and bottom by 6 and we get (24/42)
to make the denominator of (3/6) 42, we will multiply the top and bottom by 7 and we get (21/42)
these two numbers now have the same denominator so we subtract them
24/42 - 21/42 = 3/42 which simplifies to 1/14
9. since these fractions already have a common denominator, we will make them mixed fractions
-5(2/7) as a mixed fraction. first multiply 5*7 which is 35. now add 2 which is 37. our mixed fraction is -37/7
-1(5/7) as a mixed fraction. multiple 1*7 which is 7. now add 5 which is 12. our mixed fraction is -12/7
now subtract (-37/7) - (12/7) and we get -49/7 which simplifies to -7

Answer:
A. x = -2, x = 1.25
Step-by-step explanation:
<u>Use the </u><u>quadratic</u><u> formula</u>
x = 
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 = 
<u>Simplify</u>
<u>Evaluate the exponent</u>
x = 
<u>Multiply</u> the numbers
x = 
Add the <u>numbers</u>
x = 
Evaluate the <u>square root</u>
x = 
<u>Multiply</u> the numbers
x = 
<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 = 
x = 
<u>Solve</u>
Rearrange and isolate the <u>variable</u> to find each <u>solution</u>
x = - 2
x = 1.25
