Answer:

Step-by-step explanation:

1) x² - 8x + 5 = 0

2) No subtract 5 from both sides

x² - 8x + 5 - 5 = 0 - 5

x² - 8x  = -5

3) Now find (8/2) = 4. Add 4² = 16 to both sides

x² - 8x + 16 = -5 + 16

x² - 8x + 16 = 11

4) (x - 4)²  = 11

5) Take square root both sides

x - 4 = ±√11

x = 4 ±√11

Answer:

[tex]h(x) = \frac{1}{4} x[/tex]

Step-by-step explanation:

[tex]f(x) = 4x[/tex]

[tex]y = 4x[/tex]

[tex]x = 4y[/tex]

[tex]4y = x[/tex]

[tex]y = \frac{1}{4} x[/tex]

[tex]\boxed{\green{h(x) = \frac{1}{4} x}}[/tex]

Answer:

18 / 19

Step-by-step explanation:

Divide it by 2

Answer:

(A) Two acute angles add to an obtuse angle

It's sometimes because for example if you take two acute angles

one is 30 and other is 20

they add to 50 and not greater than 90 so it can be sometimes greater but not always

(B) Two adjacent angles make a line

Its also sometimes because a line means it should be 180 degrees so two adjacent angles can out always be equal to 180 that is a line

(C)Two obtuse angles are supplementary

It's Never true because obtuse angles start from 90 so if you take 91 also and other 91 too so if we add them up  that will be 182 not 180

as we know 180 = supplementary angle that's why

Answer:

A syllogism is a chain of three statements.

We need more than two operations to solve a linear equation . If an equation contains fractions, multiply both sides of the equation by the least common denominator (LCD) to clear fractions.

Answer:

26

Step-by-step explanation:

normally this should be way below your math abilities in 9th grade.

but here as a reminder :

dot operations (like multiplication and division) happen before any dash operations (addition, subtraction).

so when we go through here we see therefore

-32/8 and 5×-2 have to be calculated first (I use × instead of ., because a fit can be so easily missed or misunderstood).

and then : mind the "-" signs to actually sign all terms for the final sum.

so, -32/8 = -4

5×-2 = -10

now we have

40 - 4 - 10 = 26

Step-by-step explanation:

Ok...so yes the greater number is 7 but 7 is also the number farther from zero because when the positives and negatives are ignored, it takes 7 unit spaces to get to 7 whereas it only take 3.25 to get to the negative, making 7 farther from 0 than -3.25.

Step-by-step explanation:

In order to find miles per hour we must first change the time given to us (57.1 seconds) into hours. We will do this by first changing the seconds to minutes:

57.1 seconds / 60 = .952 minutes

Now we can change our minutes to hours:

.952 minutes / 60= .016 hours

Now to find miles per hour we divide the miles by our time:

1 mile / .016 hours = 63.04 mph

Answer:

x=-5

Step-by-step explanation:

[tex]4x = - 18 - 2 \\ x = \frac{ - 20}{4} \\ = - 5[/tex]

BESTIEEE I HOPE U CAN GIVE ME BRAINLIEST (╥﹏╥)(╥﹏╥)

4x + 2 = -18

4x = -18 - 2

4x = -20

x = -5

Answer:

well for Evey 4 completed throws she takes 7 throws

with this ratio we get that;

it's 4:7

there fore

for 12 completed free throws she would take 21 free throws

option c is the answer

hope it's helpful

Answer:

21

[tex] \huge \boxed{\mathfrak{Question} \downarrow}[/tex]

For what values of x is the equation x² − x = 20 true?

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

[tex] \sf \: x ^ { 2 } - x = 20[/tex]

Subtract 20 from both sides.

[tex] \sf \: x^{2}-x-20=0 [/tex]

To solve the equation, factor [tex]\sf\: x^{2}-x-20[/tex] using formula [tex]\sf\:x^{2}+\left(a+b\right)x+ab=\left(x+a\right)\left(x+b\right)[/tex]. To find a and b, set up a system to be solved.

[tex] \sf \: a+b=-1 \\ \sf \: ab=-20 [/tex]

As ab is negative, a and b have the opposite signs. As a+b is negative, the negative number has greater absolute value than the positive. List all such integer pairs that give product -20.

[tex] \sf1,-20 \\ \sf 2,-10 \\ \sf4,-5 [/tex]

Calculate the sum for each pair.

[tex] \sf1-20=-19 \\ \sf2-10=-8 \\ \sf 4-5=-1 [/tex]

The solution is the pair that gives sum -1.

[tex] \sf \: a=-5 \\ \sf \: b=4 [/tex]

Rewrite factored expression [tex]\sf \left(x+a\right)\left(x+b\right) [/tex] using the obtained values.

[tex] \sf\left(x-5\right)\left(x+4\right) [/tex]

To find equation's solutions, solve x-5=0 and x+4=0.

Answer:

10 red pencils because 10 is double 5 so it would be 5:10 which simplifies to 1:2

Answer:

10

Step-by-step explanation:

ratio 1 : 5

for 5 blue pencils ratio = 1

x red pencils ratio. = 2

simply 5B = 1

xR = 2

5B × 2 = R

R = 10

Therefore 10 red pencils are required

Length of distance of arc = 2πr × (∅/360)

∅ = 1/60 × 360 = 6⁰

Length = 2 × 22/7 × 3960(6/60)

Length = 44/7 × 3960 × 1/10

Length = 44/7 × 396

Length = 2489.142 cm
