5x^2 - x + 9 when x = -5
Answer:
139
Step-by-step explanation:
If x=-5
then
5*-5^2-(-5)+9
5*25+5+9
139
Answer: 139
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
Given information
5x² - x + 9
x = -5
Substitute value into the expression
=5(-5)² - (-5) + 9
Simplify exponents
=5 (25) + 5 + 9
Simplify by multiplication
=125 + 5 +9
Simplify by addition

(√17+3√48)-(√17-3√48)
Answer:
Step-by-step explanation:
[tex](\sqrt{17}+3\sqrt{48})-(\sqrt{17}-3\sqrt{48}) =\sqrt{17}+3\sqrt{48}-\sqrt{17}+3\sqrt{48}\\[/tex]
[tex]= \sqrt{17}-\sqrt{17}+3\sqrt{48}+3\sqrt{48}\\\\= 0 + (3+3)\sqrt{48}\\\\=6\sqrt{48}\\[/tex]
Now factorize 48

Y = x+1
Udbzjsjdbejdjjejejejdjejejejsjdjdjdjdjejejekieeu
Answer:
y = x + 1
Step-by-step explanation:
As x increases, y increases by 1. Therefore, the slope is 1. If we set x to 0, that'll make y equal 1. Therefore, the y-intercept is 1.
A goat is grazing outside of a rectangular barn that has dimensions 20 ft by 30 ft.
He's tied to a corner of the barn with a 12 ft rope. Find the grazing area of the goat.
Answer:
108π ft² or 339.29 ft²Step-by-step explanation:
Refer to attached picture.
The grazing area of the goat is 3/4 of area of circle with 12 ft radius:
A = 3/4(πr²) = 3/4(π*12²) = 108π or 339.29 ft²Tied to the corner
Means 1part among 4parts of circle or a quarter area
So grazing field

Answer:
x = 70
Step-by-step explanation:
To find the value of x we need to
we know that the figure is an isosceles triangle so the base angles will be equal
we also know that angle sum of triangle is 180
so
40 + x + x = 180
40 + 2x = 180
2x = 180 - 40
2x = 140
x = 140/2
x = 70
Reflect the line segment across the x-axis. Then, rotate it 90° clockwise. Finally,
translate it down 2 units. What is the relationship between the original line segment and the transformed line segment? If you
transform a line segment with a sequence of reflections, rotations, or translations, is it still a line segment?

Answer:
1 83/99
Step-by-step explanation:
This is how u do it
Answer:
[tex]\frac{183333333333}{100000000000}[/tex]
Step-by-step explanation:
1.83333333333 as fraction
we need to divide the fraction by the number of digits it have before decimal point to convert it to fraction
here we have 11 digits before decimal point so we need to divide it by 100000000000
so

[tex]x = - \frac{5}{22} [/tex]
Step-by-step explanation:
[tex]4 - \frac{2(x - 4)}{3} = \frac{3(2x + 5)}{2} [/tex]
➡️ [tex] 4x - \frac{2x - 8}{3} = \frac{6x + 15}{2} [/tex]
[tex] ➡️ 24 - 2(2x - 8) = 3(6x + 15)[/tex]
[tex] ➡️ 24 - 4x + 16 = 18x + 45[/tex]
[tex] ➡️ 40 - 4x = 18x + 45[/tex]
[tex] ➡️ - 4x - 18x = 45 - 40[/tex]
[tex] ➡️ - 22x = 5[/tex]
➡️ [tex] x = - \frac{5}{22} [/tex]

Which fraction is equal to 0.98
The most simplified version of it is 49/50
Answer:
98/100
Step-by-step explanation:
The number after the decimal is the tenths place. And the second number after the decimal is in the hundredths place. And so on...
So .98 would be in the hundredths place making it 98/100.
If you want to simplify it even more, you would make it 49/50.

Sami orders cowboy hats online for a party. They cost $11.95 each with a shipping fee of $7.95.
Sami recently paid $223.05 for some cowboy hats.
Write an equation that to find the number of cowboy hats Sami ordered. Then find the number of
cowboy hats she ordered,
Answer:
223.05/x(11.95+7.95) 11.21.
Step-by-step explanation:
If each hat costs 11.95 plus a shipping fee of 7.95, you must add those numbers together. This makes the variable that will help indicate the number of hats ordered. Then you divide 223.05 by 19.9 (the total cost per hat) and you'll get your answer of 11.21 rounded.

What are the two conditionals that form the statement below? Two numbers are reciprocals if and only if the product is one
????? what is the value of c?
Answer:
X=64°
Step-by-step explanation:
Solution,
x+54°=118° because the sum of two interior angles is equal to the opposite non adjacent exterior angle.
x+54°-54°=118°-54°
x=64°
Answer:
64 degrees
The Process:
54 is already a number that's not going to change, so that's fine. 118 is an outside angle, and a flat line is 180 degrees, so to find the inside angle, you have to do 180 - 118. Once again, there are 180 degrees in a triangle to you need to add 180 - ((180 - 118) +54) and you have the value of x.
Zeke goes to a skate shop with his friend Tristan. Tristan buys a helmet that costs $28.75. Zeke finds a helmet that is
3
5
of the cost of Tristan's helmet. If Zeke gives the cashier a $20 bill, how much change will he receive?
Answer:
Zeke will receive $2.75.
Step-by-step explanation:
Helmet cost: (3/5) x 28.75 = $17.25
Gives = $20
20 - 17.25 = 2.75
Original question:

Answer:
pi*z^2*a or "pizza"
Step-by-step explanation:
The dimensions given describe a cylinder, for which the basic volume formula would be base x height.
The base would be a circle, with the radius z as given while the height is a.
The formula for the area of a circle is pi * r^2, and our radius is z, so the area of a circle with radius z is pi * z^2.
Now, all we need to do is multiply by the height, a. This gives us a volume of pi* z^2 *a
Side note:
z^2 can be written as zz, so the actual area of the pizza could be represented by "pizza".
