Hello!
To solve this, you need to distribute and combine like terms.
Like terms are equivalent types of numbers for example;
2x and 3x are like terms, so if the equation said 2x - 5 + 3x, you would only combine 2x and 3x.
If the equation said 5 + 9 - x, you add the like terms, 5 + 9, and the simplification would be 14 - x.
Distribution is when you multiply the number outside the parenthesis into the parenthesis. for example, if an equation says, 5(x-2) = y, you would multiply 5 on the numbers x and -2, resulting in the equation, 5x - 10 = y.
--------Now lets work on your math problem.
Step 1, right the equation, 7(-9a-3)-2a7(−9a−3)−2a
Step 2: distribute numbers (remember multiplying)
7(-9a-3)-2a7(−9a−3)−2a
For the first distribution, 7(-9a-3)-2a7(−9a−3)−2a
you multiply 7 to the numbers in the parenthesis,
resulting in,
-63a - 21
Second distribution is, 7(-9a-3)-2a + 7(−9a−3)−2a
in which you multiply -7 into the numbers in the parenthesis resulting in;
-63a - 21
(did you type the equation twice if so, there are now two problems i need to solve.)
now add like terms -2a + -2a = -4a
-63a - 21 + -63a - 21 = -126a - 42
-126a - 4a - 42
Answer is -130a - 42.
If your equation was actually this, : 7(-9a-3)-2a
Then the answer would have been, -65a - 21

Which represents the inverse of the function f(x) = 4x?
h(x) = x + 4
h(x) = x-4
h(x) = =x
h(x) = ÷x
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]
The ratio of a basketball player's completed free throws to attempted free throws is 4 to 7. If she completed 12 free throws, find how many free throws she attempted.
a. 3 free throws
b. 7 free throws
c. 21 free throws
d. 4 free throws
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
Step-by-step explanation:
FreeThrows: FT
Attempted Throws: AT
FT/AT=4/7
12/AT=4/7
84/4=AT
AT=21
Find the distance along an arc on the surface of the earth that subtends a central angle of 1 minute(s) (1 minute = 1/60 degree). The radius of the earth is 3960 miles. Round to the thousandths. (3 decimal places)
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

How would I plot and label the numbers 6.5 & 8.5 on a number line to write a inequality using the symbol “>” to compare the two numbers
Answer:
To label 6.5 on a number line, put the plot between the 6 and 7.
Same thing goes for 8.5, except the plot would go between the 8 and 9.
8.5 > 6.5
Step-by-step explanation:
1.) Since 8.5 and 6.5 are decimals, they are not a whole number which is why they go right in the middle of the two numbers they are behind and in front of.
2.) > means greater than, and 6.5 is smaller than 8.5 therefore we use the greater than sign, pointed towards the 8.5.
I hope this helps! :)
For what values of x is the equation x2−x=20 true?
[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.
[tex] \bf \: x=5 \\ \bf x=-4[/tex]

The greater number is 7
The number farther from O is
Explain your reasoning.
B
1
U
!!!
T
T.
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.

Refer to the graphic novel frame below. Seth traveled 1 miles in 57.1 secs. About how fast does Seth travel miles per hour?
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

S(-4, -6) and T(-7, -3); Find R.
Answer:
(13,-6)
Step-by-step explanation:
The midpoint is the exact halfway point, so all you need to do is find the distance between those two points and apply it again.
First find the x coordinate. The distance from -9 to 2 is 11. So you add 11 to 2, and you get 13, which is your x coordinate.
Then do the same thing with the y coordinate. And you get -6.
Your endpoint is (13,-6)

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

We know that, Two angles are said to be complementary, if the sum of their measures is 90°.
According to the Question,
⇒ ∠ABD + ∠DBC = 90°
⇒ (2x + 30)° + (3x + 20)° = 90°
⇒ 2x + 30° + 3x + 20° = 90°
⇒ 5x + 50° = 90°
⇒ 5x = 90° - 50°
⇒ 5x = 40°
⇒ x = 40°/5
⇒ x = 8
So, the measure of each angle will be,
⇒ ∠ABD = (2x + 30)°
= 2 × 8 + 30°
= 16 + 30°
= 46°
⇒ ∠DBC = (3x + 20)°
= 3 × 8 + 30°
= 24 + 30°
= 54° ▄▄▄▄▄▄▄▄▄▄▄▄▄▄is fraction a linear equation

[tex]\text{Suppose the width of the rectangle is }x\text{ cm}[/tex]
[tex]\text{then the perimeter can be expressed as}[/tex]
[tex]2(24+x)=72[/tex]
[tex]24+x=36[/tex]
[tex]x=12[/tex]
[tex]\text{Therefore the area of the rectangle is }24\cdot x=24\cdot 12=288\text{ cm}{}^2[/tex]
Answer: Solution,
length (l) = 24 cm
perimeter (p)= 74 cm
Area (A) = ?
we know,
P = 2(l + b )
74 = 2( 24 + b)
74 = 48 + 2b
2b = 74 - 48
2b = 26
b= [tex]\frac{26}{2}[/tex]
b = 13
now,
A = l*b
= 24 * 13
= 312 cm square
Therefore, the area of the rectangle is 312 cm square.
