factorsie x squared + 5x-14
Answer:
(x+7)(x-2)
Step-by-step explanation:
=x^2+5x-14
=x^2+(7-2)x-14
=x^2+7x-2x-14
=x(x+7)-2(x+7)
=(x+7)(x-2)
Answer: (x+7)(x-2)
We're looking for two numbers that multiply to -14 and also add to 5. Through trial and error, you should find those numbers are 7 and -2.
You can use the FOIL rule to confirm that (x+7)(x-2) expands out to x^2+5x-14
(x+7)(x-2) = x^2-2x+7x-14 = x^2+5x-14
Find the slope of the line that contains (−9, 1) and (3, 6).
Answer:
5/12
Step-by-step explanation:
slope is [tex]\frac{1y-2y}{1x-2x}[/tex]
so [tex]\frac{6 - 1}{3 - (-9)}[/tex] and that is 5/12

How do I solve for c
Answer:
Uhhh add the top then divide by bottom
Step-by-step explanation:
Bc yes
Answer:
[tex] c = \dfrac{3e + 3d - 5D}{2b} [/tex]
Step-by-step explanation:
[tex] \dfrac{2bc + 5D}{3} = e + d [/tex]
Multiply both sides by 3.
[tex] 2bc + 5D = 3(e + d) [/tex]
[tex] 2bc + 5D = 3e + 3d [/tex]
Subtract 5D from both sides.
[tex] 2bc = 3e + 3d - 5D [/tex]
Divide both sides by 2b.
[tex] c = \dfrac{3e + 3d - 5D}{2b} [/tex]
What slope is perpendicular to:
m = 5/8
The slope that is perpendicular to m = 5/8 is given by; m' = -8/5
When dealing with slope - intercept form of equation of a line, the general equation is;y = mx + c
where;
m is the slope
c is the y-intercept
Now, for a line to be perpendicular to a line above that has it's slope as m, the slope of this new line will be the negative inverse of the first slope. This is; m' = -1/mApplying that to our question, it means the slope that is perpendicular to m = 5/8 is; m' = -1/(5/8) = -8/5Read more at; https://brainly.com/question/21441448

2 + 3( 4x + 5) = -53
Answer:
x=-35/6
Step-by-step explanation:
2 + 3( 4x + 5) = -53
subtract 2 from both sides= 3(4x+5)=-55
divide both sides by 3 = 4x+5=-55/3
subtract both sides by 5 = 4x=-70/3
divide both sides by 4 = x=-35/6
x=-35/6 is your final answer
Answer:
Hope this helps :)
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable.
Exact Form:
x=−35/6
Decimal Form:
x=−5.8¯3 (Repeating)

Answer:
There are 15.748 inches in 40cm. Can I please have brainlest?
Step-by-step explanation:
Answer:
40cm
Step-by-step explanation:
If you are converting 40cm to one inch and the conversion ratio is 2.54 : 1, you would place 40 in the numerator as the original ration has 2.54/1 as a fraction and the same will apply to 40cm.
** This applies if you are finding which number is in the numerator and not the answer to how much 40cm in inches is.
