Substitute -9 for every x.
-3(-9)^2 - 6(-9)
Multiply and get final value.
-243 - 6(-9)
-243 + 54
Answer: -189
Answer:
f(-9) = -189
Step-by-step explanation:
f(x) = -3x² - 6x
Plug in -9 for x.
f(-9) = -3(-9)² - 6(-9)
According to PEMDAS (parentheses/exponents | multiplication/division | addition/ subtraction), we should solve the exponents first.
f(-9) = -3(81) - 6(-9)
Now, multiply.
f(-9) = -243 + 54
Now, add.
f(-9) = -189
This is your answer.
Hope this helps!

Carlos is a member of a gym. He pays a monthly fee plus a per- visit fee. The equation y = 3x + 10 represents the monthly amount Carlos pays for x visits.
if Carlos pays $85 in the last month how many times did he visit the gym?
Answers
Answer:
25 times
Step-by-step explanation:
To find how many times he visited, plug in 85 as y and solve for x:
y = 3x + 10
85 = 3x + 10
75 = 3x
25 = x
So, Carlos visited the gym 25 times

Entry tickets for a firework display were charged at £10
for children and £25 for adults. 800 people attended
the event and the ratio of adults to children was 7:9.
a.
Work out the total revenue from ticket sales
b.
60% of the tickets cost was given to charity.
How much was given to charity?
Answers
Answer:
Total revenue = $13,250
Amount given for charity = $7,950
Step-by-step explanation:
Children = $10
Adults = $25
Total people = 800
ratio of adults to children was 7:9.
Total ratio = 7 + 9 = 16
Adults = 7/16 × 800
= 0.4375 × 800
= 350
Adults = 350
Children = 9/16 × 800
= 0.5625 × 800
= 450
Children = 450
Total revenue = ($10 × 450) + ($25 × 350)
= $4,500 + $8,750
= $13,250
Total revenue = $13,250
60% of the tickets cost was given to charity.
Amount given for charity = 69% of $13,250
= 0.60 × $13,250
= $7,950
Amount given for charity = $7,950

8x2 - 6x + 3 – 2x – 10x?
Answers
Answer:
8[tex]x^{2}[/tex] + 3 + -6x
Step-by-step explanation:
First we need to find the like terms so that we could add them. In this case the like terms are,
1. 6x , -2x , -10x
So, these are the only terms that we can add in this expression.
Hence,
=> 8[tex]x^{2}[/tex] + 3 + (6x - 2x - 10x)
=> 8[tex]x^{2}[/tex] + 3 + -6x
And this is as simple as this expression can go until we find the value of "x" which is not yet told.

"7x^2+19x-6 = 0
Answers
Step-by-step explanation:
Given
7x² + 19x - 6 = 0
7x² + (21 - 2) x - 6 = 0
7x² + 21x - 2x - 6 = 0
7x( x + 3 ) - 2 ( x + 3 ) = 0
(x + 3 ) ( 7x - 2 ) = 0
Either
x + 3 = 0
x = - 3
Or,
7x - 2 = 0
7x = 2
x = 2 /7
So
x = - 3 and 2/7
Hope it will help :)
Answer:
x= -3,/2/7
Step-by-step explanation:
split the second term in 7x^2 + 19x-6 into two terms 7x^2+21x-2x-6=0
Factor out common terms in the first two terms7x(x+3)-2(x+3)=0
(x+3)(7x-2)=0
Factor out the common term x+3 hope that help x= -3,/2/7

6.28 + 24 + 3 + 2 = 35.28 sq. units
Step-by-step explanation:
The screenshot is how I split it. (A semicircle with a radius of 2, a trapezoid (base a: 5, base b: 7, height 4), and two triangles (b1: 3, h1: 2; b2: 4, h2: 1)
To find the area of a semicircle, use the formula πr²/2. I'll use 3.14 for pi.
3.14(2²)/2
Square 2 to get 4.
3.14(4)/2
Multiply 3.14 by 4 to get 12.56.
12.56/2
Divide 12.56 by 2 to get 6.28
The semicircle is 6.28 units².
To find the area of a trapezoid, use the formula (a+b)h/2.
(5 + 7) * 4/2
Add 5 and 7 to get 12.
(12 * 4)/2
Multiply 12 by 4 to get 48.
48/2
Divide 48 by 2 to get 24.
The trapezoid is 24 units².
For the triangles, simply use this: bh/2
3 * 2 / 2
The 2's cancel out, so you're simply left with the first triangle being 3 units².
4 * 1 / 2
This really just becomes 4/2 as 4 * 1 is just 4.
4/2
Divide 4 by 2 to get 2.
The second triangle is 2 units².
Now that we know the areas of the four figures, add them together.
6.28 + 24 + 3 + 2
6.28 + 27 + 2
6.28 + 29
The area of the figure is 35.28 units².
