I need help ASAP. I am terrible at math

Answer:

h(-3) = 51

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Step-by-step explanation:

Step 1: Define

h(x) = 4x² - 5x

h(-3) is x = -3

Step 2: Evaluate

Answer:

f(-3) = 51

Step-by-step explanation:

f(x) = 4x^2 - 5x

f(-3) = 4(-3)^2 - 5(-3)

f(-3) = 4*9 - (-15)

f(-3) = 36 + 15

f(-3) = 51

Answer:

point slope form: y - 1 = 4 (x -2)

slope intercept form: y = 4x -7

Step-by-step explanation:

If you want it in point slope form it would be: y - 1 = 4 (x -2)

but if you want it in slope intercept form, you solve this equation

y -1 = 4 (x-2)

y-1 = 4x -8

 +1          +1

y = 4x -7 in slope intercept form

Answer:

[tex]x=2,\\x=-2,\\x=\sqrt{3},\\x=-\sqrt{3}[/tex]

Step-by-step explanation:

This is a quadratic in disguise. Let [tex]n=x^2[/tex]. We can rewrite the problem as a quadratic to solve:

[tex]n^2-7n+12=0,\\(n-3)(n-4)=0,\\n=3,\: n=4[/tex].

Now plug in these values of [tex]n[/tex] to solve:

[tex]\begin{cases}x^2=4, \:x=\pm 2\\\\x^2=3, x=\pm\sqrt{3}\end{cases}[/tex].

Therefore, our solutions are [tex]x=\pm 2, \:x=\pm\sqrt{3}[/tex].

Answer:

The correct answer is

Answer:  The amount of white fabric to coloured fabric as a ratio in its simplest form is [tex]\frac{10}{11}[/tex]

Step-by-step explanation:

Given :

Amount of coloured fabric used by June = 11 mm = 1.1 cm    (1 mm=0.1 cm)

Amount of white fabric used by June = 1 cm

To find : amount of white fabric to coloured fabric as a ratio in its simplest form

To find the ratio in simplest form , the units of both measurements should be same

Thus [tex]\frac{\text {amount of white fabric}}{\text {amount of coloured fabric}}=\frac{1cm}{1.1cm}=\frac{10}{11}[/tex]

The amount of white fabric to coloured fabric as a ratio in its simplest form is [tex]\frac{10}{11}[/tex]

Answer:

2 gigabytes of data

Step-by-step explanation:

Given

Amount Jason keeps per month = $68.90

Cost of flat per month = $60.50

Balance for data = 68.90-60.50

Balance for data = $8.40

If 1Gigabyte = $4

x = $8.40

Cross multiply

4x = 8.40

x = 8.40/2

x = 2.20

Hence Jason can only use 2 gigabytes of data while staying within his budget

Answer:

2.1 gigabytes

Answer:

One day Bob asked him mom if she could buy him a Ps5. She replied "No Bob, if you really want it you have to buy it yourself. And don't you already have that PlayStation 2 your grandma gave you?" After Bob heard that he ran out of the house to go find a job. He ran up to Mc Donald's and saw that they don't hire 15 year old's. Sadly he walked away. Then he ran up to Burger King they don't hire 15 year old's either. Then h realized he could deliver newspaper on his bike. So he went home told his mom and she was happy when he told her his idea.  The next morning he set out to his new job. As he got there he realized he didn't eat breakfast but that was fine he wasn't hungry he was to happy to think about anything else but that new Ps5. He got the newspapers and started going. After he delivered 27 newspapers it started getting dark so he went home. The next day went just like the first but he actually ate breakfast. Weeks went by throwing newspapers cycling, throwing newspapers cycling, throwing newspapers cycling. After 3 months he got his paycheck, just enough for the Ps5! Happily he went to the bank cashed it out and biked to target. He parked his bike ran into target into the electronics aisle scanning for the new Ps5.  Then the worker asked him politely "What are you looking for?" "A Ps5." He responded quickly. "Oh.." The worker said "Were sold out..."

width=17m

length= 31m

Step-by-step explanation:

width = x

length= x+14

perimeter = 96m

2(x+x+14)=96

4x+28=96

4x=68

x=17

width=17m

length= 31m

Answer:4

Step-by-step explanation:

6,-2=x-3=4

======================================================

Explanation:

M is the midpoint of segment PQ. This means PQ is cut in half into two equal smaller pieces PM and MQ. We can say that PM = MQ.

Furthermore, we can say that PQ is twice as long as either piece, so

We'll use the second equation to say the following:

PQ = 2*MQ

6x+56 = 2*MQ .... replace PQ with 6x+56

6x+56 = 2*(5x+8) .... replace MQ with 5x+8

6x+56 = 2*5x + 2*8 .... distribute

6x+56 = 10x+16

6x+56-10x = 16 .... subtract 10x from both sides

-4x+56 = 16

-4x = 16-56 ..... subtract 56 from both sides

-4x = -40

x = -40/(-4) ..... divide both sides by -4

x = 10

Once we know the value of x, we use it to find the length of PM

PM = MQ

PM = 5x+8

PM = 5*10+8

PM = 50+8

PM = 58

Note how PQ = 6x+56 = 6*10+56 = 116 is exactly twice as large compared to 58. In other words, 2*58 = 116. This confirms that PQ is twice as long compared to PM or MQ. This helps confirm we have the right answer.

Answer:

5 units of football

Step-by-step explanation:

Given that :

2.5 times as many footballs as basket balls is sold;

This means that ; for every unit of basketball sold 2.5 times that unit is the number of football sold ;

Hence, for every 2 basket balls sold, the number of units of football sold is ;

2 * 2.5 = 5 units

Answer:

The inequality which represents the model for this situation is [tex]x-6\geq 17[/tex].

Step-by-step explanation:

Let Mr. Garcia has [tex]x[/tex] number of desks initially.

He has been asked to give [tex]6[/tex] desks to Mrs. Johnson.

Also, he needs to keep at least [tex]17[/tex] desks for his students.

So, after giving [tex]6[/tex] desks to Mrs. Johnson from the total number of desks he has, he must have at least [tex]17[/tex] desks for his students.

Therefore, the inequality is: [tex]x-6\geq 17[/tex].

Hence, the inequality which represents the model for this situation is [tex]x-6\geq 17[/tex].
