because f(x) is y=2*2=4
Answer:
Step-by-step explanation:
You have to understand two things about this question.
f(x) is a relative of y. So maybe it would help you if you wrote y = 2x^2The second thing you have to understand is when you see a number used instead of the x, that number goes into every x on the right.f(-3) = 2(-3)^2
f(-3) = 2 * 9
f(-3) = 18
Remember that (-3) ^2 = -3 * - 3 = 9 a positive.

Step-by-step explanation:
d =√[(-3+9)²+(6+2)²]
= √(6²+8²)

=√100
= 10
Answer:
[tex]\boxed {\boxed {\sf d=10}}[/tex]
Step-by-step explanation:
The distance between two points can be calculated using the following formula.
[tex]d= \sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
In this formula, (x₁, y₁) and (x₂, y₂) are the two points. We are given the points (-9, -2) and (-3,6). If we match the value with the corresponding variable we see that:
x₁= -9 y₁= -2 x₂= -3 y₂= 6Substitute the values into the formula.
[tex]d= \sqrt {(-3 - -9)^2 + (6 - -2)^2[/tex]
Solve inside the parentheses. Remember that 2 back to back negative signs become a plus sign.
(-3 - -9)= (-3+9)= 6 ( 6- -2)= (6+2) =8[tex]d= \sqrt{ (6)^2 + (8)^2[/tex]
Solve the exponents. Multiply the number by itself.
(6)²= 6*6= 36 (8)²= 8*8= 64[tex]d= \sqrt{(36)+(64)[/tex]
Add.
[tex]d= \sqrt{100[/tex]
Take the square root of the number.
[tex]d= 10[/tex]
The distance between the points (-9, -2) and (-3, 6) is 10.

Answer:
x = -1
Step-by-step explanation:
5(2x – 3) = -4(x + 4) – 13
Use distributive property,
5*2x - 5*3 = -4*x +(-4)*4 -13
10x - 15 = -4x - 16 - 13
10x - 15 = -4x - 29
Add 15 to both sides
10x = -4x -29 + 15
10x = -4x - 14
Add 4x to both sides
10x + 4x = -14
14x = -14
Divide both sides by 14
x = -14/14
x = -1

Carson buys eggs and lemons at the store.
He pays a total of $39.62.
He pays $6.74 for the eggs.
He buys 8 bags of lemons that each cost the same amount.
Which equation could be used to determine xx, how much each bag of lemons costs?
Answers
Answer: 8x = $39.62 - $6.74
Step-by-step explanation:
Cost of 1 bag of lemons = $x
Cost of 8 bags of lemons = 8*x = 8x
Cost of 8 bags of lemons = Total cost - cost of the egg
8x = $39.62 - $6.74

2 and 13
Step-by-step explanation:
2+13=15
and
2x13=26
[tex]\large \mathfrak{Solution : }[/tex]
let the numbers be x and y
now, we know that
x + y = 15 - Equation (1)xy = 26 - Equation (2)by squaring Equation (1) :
(x + y)² = 15²x² + y² + 2xy = 225x² + y² - 2xy + 4xy = 225(x - y)² + (4 × 26) = 225(x - y)² + 104 = 225(x - y)² = 225 - 104(x - y)² = 121x - y = 11 x = 11 + y - Equation (3)
Plugging the value of x from Equation (3) into Equation (1)
x + y = 1511 + y + y = 152y = 15 - 11y = 4 ÷ 2y = 2 - Equation (4)now, let's plug the value of y from Equation (4) into Equation (3) :

Step-by-step explanation:
11. Angle A and B are supplementary (add to 180)
And measure of Angle A is 2x+30 and measure of angle B is 6x-12. All you have to do is make an algebraic expression.
180= (2x+30) + (6x-12)
Then just combine like terms and you get
8x+18=180.. Subtract 18 and you get
8x=162 then divide by 8 and you get
X=20.25
Then plug in the number and you get
180=(2*20.25+30)+(6×20.25-12)
Which is is transferred to
180=(70.5) +(109.5)
Which is 180=180.

A rectangular block of fin is 0.5 m long and 0.0lm thick Find the width of the block if its mass and density are 0.45 kg and 9000kgm-³ respectively
Answers
Answer:
Step-by-step explanation:
This is going to give you a preposterous answer. The width is into the millions.
density = 9000 kg / m^3
mass = 0.45 kg
V = density / mass
V = 9000 / 0.45 = 20000 m^3
V = L *w * h
L = 0.5 m
h = 0.01 m
w = ?
20000 = 0.5 * 0.01 * w
20000 / (0.5 * 0.01) = w
w = 4000000 m
