What is the value of h(-2) if h(x)=4x^2-x+9?

Answer:

4x +  -6.03 = 2.07

Step-by-step explanation:

first one:

there are four big white boxes so that equals 4x

6 negative ones so its -6

3 negative 0.1 so its -0.3

add up 06 and -0.3 and that's -6.03

second one:

there are two squares that each equal one so that would be two and add the 7 0.1's and that will be 2.07

Answer:

B. 135, 45, 15, 5...

Step-by-step explanation:

I'll go in order from 135 using the pattern shown (tᵇ/3)

135 / 3

135 = 120 + 15

135/3 = (120/3) + (15/3)

135/3 = 40 + 5

135/3 = 45

All four answer choices show this, so no elimination yet.

45 / 3

45 = 30 + 15

45/3 = (30/3) + (15/3)

45/3 = 10 + 5

45/3 = 15

A and D show 30 as term 3, so they are out.

15 / 3

15/3 = 5

C shows 2 as term 4, so that is also out.

This leaves B as the correct answer.

Answer: x < -1

Step-by-step explanation:

x + 6 < 5

x + 6 = 5

x = -1

x < -1

Now try to prove its correct

A number less than -1 is -2 so we'll try that.

x + 6 < 5

(-2) + 6 < 5

4 < 5

We can tell after substituting -2 for x, that the answer is correct

Oh and I changed the less than sign to an equal sign so it's easier to solve.

Does that help?

Step-by-step explanation:

the difference of 2x and 15 is less than or equal to the

sum of 4x and 17

i.e.,

2x - 15 < 4x + 17

if you want to find ahead then

2x - 15 = 4x + 17

2x - 4x = 17 + 15

- 2x = 32

x = - 32/2

x = - 2

Answer:

11.5

Step-by-step explanation:

Find new values:  

140(1+0.05)=147  

68(1+0.25)=85

Last Year This Year

Boys 140 147

Girls 68 85

Total 208 232  

Find overall increase:  

208(1+r)=232

1+r=1.115385  

r=0.115385

Final Answer: 11.5%

The total number of students on the honor roll increased by 11.5%.

The percentage is defined as a ratio expressed as a fraction of 100.

The percentage increase in the number of boys on the honor roll is 5%, which means that the number of boys on the honor roll this year is 1.05 times the number of boys on the honor roll last year:

1.05 x 140 = 147

The percentage increase in the number of girls on the honor roll is 25%, which means that the number of girls on the honor roll this year is 1.25 times the number of girls on the honor roll last year:

1.25 x 68 = 85

Therefore, the total number of students on the honor roll this year is:

147 + 85 = 232

The percentage increase in the total number of students on the honor roll is:

((232 - 208) / 208) x 100% = 11.5385%

Rounding to the nearest tenth gives an answer of 11.5%.

Therefore, the total number of students on the honor roll increased by 11.5%.

Answer: 38.34 inches

Step-by-step explanation:

The lamp is round which means that the circumference can be calculated by the formula:

= Pie * diameter

Pie = 22/7

Diameter = 12.2

Circumference = 22/7 * 12.2

= 38.34 inches

Answer:

y=-3/2x+8

Step-by-step explanation:

Alright so first we need to convert this equation to Y=mx+b form.

We get y=2/3x-2

In order for it to be perpendicular, we must use -3/2 as the slope.

y=-3/2x+b

Next we need to find the y-intercept of this

Plug in 6 for x and -1 for y and solve for b

b=8
