i need help, can someone show me how to solve it
Answer:
9
Step-by-step explanation:
Simply plug -3 in for x.
-2(-3)^2-7(-3)+6
(-3)^2=9
9*-2= -18
-7*-3=21
-18+21=3
3+6=9
Answer:
f(-3) = 9
Step-by-step explanation:
Here we have a quadratic function in x: and we want to know the value of this function when x = -3.
Substituting -3 for x in f(x) = -2x^2 - 7x + 6, we get f(-3) = -2(-3)^2 - 7(-3) + 6, which works out to f(-3) = -2(9) + 21 + 6, or
f(-3) = -18 + 27 = 9
Thus, f(-3) = 9
Jim rented a truck for one day . There was a base fee of $18.95 and there was an additional charge of 74 cents for each mile driven . Jim had to pay $119.59 when he returned the truck . For how many miles did he drive the truck ??
Answer:
136 miles
Step-by-step explanation:
subtract $119.59 with how much he rented the truck for, which is $18.95 which makes his money at $100.64, then divide by how much each mile costed which was 74 cents
which gives you 136 so 136 miles.
Hope this helps :)
3) if the cost of 1 pen is Rs.10, find the cost of 5 pen
Answer: 5 pens cost Rs.50
Explanation: Since 1 pen costs Rs.10, you will need to multiply the number of pens (1) and the cost of that number of pens (Rs.10) by the amount of pens you must find the cost for (5). Since 10 times 5 is 50, that means that 50 is the cost of 5 pens.
I hope this helps!

using the remainder theorem which quotient has a remainder of 20?
Answer:
D
Step-by-step explanation:
When a polynomial f(x) is divided by (x - a) then remainder is f(a)
A
divided by (x + 4 ), then a = - 4
[tex](-4)^{4}[/tex] - 8(- 4)² + 16 = 256 - 128 + 16 = 144 ≠ 20
B
divided by (x - 2), then a = 2
3(2)³ + 7(2)² + 5(2) + 2
= 3(8) + 7(4) + 10 + 2
= 24 + 28 + 12 = = 64 ≠ 20
C
divided by (x + 5) , then a = - 5
(- 5)³ + 5(- 5)² - 4(- 5) + 6
= - 125 + 125 + 20 + 6 = 26 ≠ 20
D
divided by (x - 2), then a = 2
3[tex](2)^{4}[/tex] - 5(2)³ + 5(2) + 2
= 3(16) - 5(8) + 10 + 2
= 48 - 40 + 12 = 20 ← Remainder of 20

A house cleaning company charges a constant rate for each hour of cleaning. They charge $135 for 3 hours of cleaning.
Number of hours cleaning
Amount charged for cleaning (in dollars)
3
$135
18
How much would the company charge for 18 hours of cleaning?
$675
⊝
$810
⊝
$2,430
⊝
$45
⊝
Answer: $810 (B)
Step-by-step explanation: first youd need to find how much they pay for 1 hour. In this case, itd be 135/3 = 45. now multiply by 18 (because 1 hr x 18 = 18 hrs). this would get you to 810.
A company that teaches self-improvement seminars is holding one of its seminars in
Hampton. The company pays a flat fee of $69 to rent a facility in which to hold each session.
Additionally, for every attendee who registers, the company must spend $15 to purchase
books and supplies. Each attendee will pay $18 for the seminar. Once a certain number of
attendee register, the company will be breaking even. How many attendees will that take?
What will be the company's total expenses and revenues?
Step-by-step explanation:
I take it that the $69 flat fee is for one event.
and we are talking about one event overall.
"breaking even" means that the sum of all expenses and revenues is 0.
so, with x being the number of attendees,
0 = 18x - 15x - 69
69 = 3x
x = 23
that means, with 23 attendees they will break even, and with every attendee more they will gain.
in the case of 23 attendees the company will have expenses of 69 + 23×15 = $414.
and the revenues are 23×18 = $414

Answer:
[tex]2(x+11y)[/tex]
Step-by-step explanation:
Rearrange:
[tex]10x-7x-x+13y+9y[/tex]
Subtract and Add:
[tex]2x+22y[/tex]
Simplify:
[tex]2(x+11y)[/tex]
Answer:
x + 11y
Step-by-step explanation:
Working in parts starting with x...
10x-7x = 3x
3x - x = 2x
Moving on to y...
13y + 9y = 22y
Put it together
2x + 22y
Simplify by dividing both by a common number ( in this case 2)
x + 11y

solve v 2v-11=17
Answer:
v = 14
Step-by-step explanation:
Add 11 to both sides of the equation
2v-11+11 = 17+11
Simplify. (à la, add the numbers)
2v = 28
Divide both sides of the equation by 2
v = 14

Lena's Coffee Shop makes a blend that is a mixture of two types of coffee. Type A coffee costs Lena S4.10 per pound, and type B coffee costs $5.95 per
pound. This month's blend used twice as many pounds of type B coffee as type A, for a total cost of $336.00. How many pounds of type A coffee were used?
Answer: Just bought 21 pounds of coffee A
Step-by-step explanation:
We know that she consumed twice as many pounds of Type B coffee as type A.Then let the total number of cafe feet A=x ; then the number of cafe feet B=2x . We also know that the total number of feet cost $336And the fact that one pound of coffee A costs $ 4.1 ; and one pound of coffee B costs $ 5.95 Then :[tex]\large \boldsymbol {} 2x\cdot 5,95 +x\cdot 4,1 =336 \\\\ 11,9x+4,1x=336 \\\\ 16x=336 \\\\ \boxed{x=21}[/tex]Solving Two Step Equations
3(x + 4) - 5 = 2x + 4
Answer:
-3=x
Step-by-step explanation:
3(x+4)-5=2x+4
use distributive property to get:
3x+12-5=2x+4
simplify to get:
3x+7=2x+4
subtract 4 from both sides to get:
3x+3=2x
subtract 3x from both sides to get:
3=-x
multiply both sides by -1 to get your answer:
-3=x

I NEED HELP ASAP PLEASE NO LINKS!!!
Answer:
-31/4
Step-by-step explanation:
[tex]\frac{1}{2} ^{2}[/tex] is actually just (1/2)(1/2) and that equals 1/4
2 - (2/3) you can simplify to (6/3) - (2/3). that equals 4/3
now put it together!
(1/4) - 6(4/3)
(1/4) - (24/3) --------> (which simplifies to 8)
1/4 - 8 ----> (now you have to simplify this to match 1/4 denominator)
(1/4) - (32/4)
-31/4

x=7
Step-by-step explanation:
If you like my answer than please mark me brainliest thanks
Answer:
x = 7
Step-by-step explanation:
Step 1: Add 6 to both sides.
[tex]3x - 6 + 6 = 15 + 6[/tex] [tex]3x = 21[/tex]Step 2: Divide both sides by 3.
[tex]\frac{3x}{3} = \frac{21}{3}[/tex] [tex]x = 7[/tex]Step 3: Plug in the value to see if it's correct.
[tex]3(7) - 6 = 15[/tex] [tex]21 - 6 = 15[/tex] [tex]15 = 15[/tex]Therefore, x = 7.
