Answer 2

Answer:

D. y = -2x - 10

Step-by-step explanation:

Slope- intercept form:

y = mx + b

In the process of solving it was found that:

m = -2 and b = -10

The equation therefore is:

y = -2x - 10

Correct choice is D

Determine
f(a + h) - f(a)
for f(x) = 1 - x2 and simplify.

Answers

Answer:

h^2+2ah

Step-by-step explanation:

When f(x) = 1-x^2

f(a) = 1 - a^2

f(a+h) = 1 - (a+h)^2

= 1 - a^2 + 2ah + h^2

Subtracting the two:

f(a+h) - f(a)

= (1 - a^2 + 2ah + h^2) - (1-a^2)

= 1 - 1 - a^2 + a^2 + 2ah + h^2

= 2ah + h^2

= h^2 + 2ah

The number of women elected to the us house of representatives has increased nearly every congress since 1985 in ths 99th Congress to beginning in 1985 there were 22 female representatives in the 109th Congress beginning in 2005 there were 68 female representatives write a linear eauation that models the number of female members lf the house of representatives x years after 1985

Answers

Answer:

y = 2 · 3 x + 22

Step-by-step explanation:

Analysis: Number of female representatives in 1985 = 22

This can be represented by the point (0,22).

Number of representatives in 2005 = 68.

This can be represented by the point (2205-1985,68)

= (20,68)

Slope of the line : [tex]\frac{68-22}{20-0} =\frac{46}{20} =\frac{23}{10} =[/tex] 2 · 3

∴ Equation of the line :  y = mx + c

⇒ 22 = 2 · 3 (0) + c

⇒ C = 22

∴  y = 2 · 3 x + 22

As the school’s sign language interpreter, Kiran gets paid $34 for every parent-teacher conference that he attends. He also gets paid $22 per school-related assembly that he attends as an interpreter. If Kiran earns $1008 for 36 paid events, how many parent-teacher conferences and how many school-related assemblies did he attend ?

Answers

Kiran atttended 18 parent-teacher conferences and 18 school-related assemblies.

Let x represent the number of parent-teacher conference and y represent the school-related assembly.

Since Kiran earns $1008 for 36 paid events, hence:

x + y = 36    (1)

34x + 22y = 1008    (2)

Solving equations 1 and 2 simultaneously gives:

x = 18, y = 18

Therefore Kiran atttended 18 parent-teacher conferences and 18 school-related assemblies.

Follow the steps below!

Step-by-step explanation:

If you're provided with a graph then use that, but if not, draw it with a scale of 1 unit per 1 tick and all four quadrants.

Start at -2 on your y-axis (two ticks down from the origin the vertical line) and draw a dot or cross. Then, go to the right one tick and up one tick and draw another dot or cross. If you do this again, you should have made a mark on the x-axis (horizontal line). All you need to do is draw a straight line connecting the points you plotted with arrows on the end. You can use a ruler  or other straight edge if straight lines are a challenge to draw.

Change all the signs in the second polynomial because it has a negative sign before the parentheses.

= 2xy - 4x^2 - 9y - 3x^2 + xy

what is the value of Y

Answers

Answer:

y = 150º

Step-by-step explanation:

The sum of internal angles of a triangle must be 180º and the sum of y + (x-20) forms a straight line which is also 180º, so:

2x + x + (x - 20) = 180

4x - 20 = 180

4x = 200

x = 50

x - 20 = 50 - 20

x - 20 = 30

y = 180 - 30

y = 150º

Answers

Answer:

a) 5/4

b) y = 5/4x + 27

Step-by-step explanation:

To find the gradient of a line, simply change the equation into slope intercept form (y = mx + b), where b is the y-intercept and m is the slope.

4y - 5x = 2

4y = 5x + 2

y = 5/4x + 1/2

m(gradient) = 5/4

For lines to be parallel, simply keep the gradient the same.  Any line with a gradient, or slope, of 5/4 will be parallel. As such, simply keep the first two terms identical, and change the y-intercept into any number.

Geometry

Answers

Answer:

m∠6 = 54°

Hope this helps!

Step-by-step explanation:

( 13x+9 ) and angle 4 are congruent meaning the same. That means angles 5 and 8 are also congruent to ( 13x + 9 ).

Angle 5 or angle 8 are Supplementary to angle ( 5x + 9 ) so a Supplementary angle is 180° and we need to find out x.  ( 13x + 9 ) + ( 5x + 9 ) = 18x + 18.

Because Supplementary angles equal 180°, 18x + 18 = 180

18x = 162        x = 162/18       x = 9

Because ∠6 is congruent to angle ( 5x + 9 ), ∠6 = ( 5(9) + 9 )

∠6 = 45 + 9        ∠6 = 54

The school let out because the storm was arriving, and it didn't have a cellar big enough to hold all the students of Nopali School. Since most of them lived nearby, the school allowed them to go home before the storm hit. The students' cheers and whistles could be heard over the thunder and whirring winds that whipped through the schoolyard. August, for just one second, watched them all cheer in glee and wanted so much to join them, but instead, she began running. As August ran home, she could feel every step in her lungs. It felt like a hundred little lightning bolts shooting down her mouth and into her chest. She wanted to stop. She wanted to catch her breath. She even wanted to turn around to see if the clouds were chasing her down, but all she could think about was her family and her dog Mutton. She wanted to get to them desperately and hoped to see an abandoned house with all of them in the cellar in the backyard. Behind her, the wind whipped up every bit of gravel and dust into the air. The dust and debris filled the air and clouded the air like cream being stirred into a cup of black coffee. The sky looked like an antique picture. The once blue sky was now a sepia tone that August had only seen in old pictures. It was beautiful in a way, like some sort of painting. The only problem with tornadoes was that in addition to all of the beauty they painted in the sky, they also brought about destruction. In fact, August's school had been rebuilt twice because tornadoes had brought it down twice in the last 5 years. August remembered the desks splintered into two, looking like broken bones, the brass bell twisted and tangled like a ball of twine, the roof with holes the size of tractors. She knew first-hand how a tornado could bend a town until it broke. This knowledge is what kept her running. This knowledge is what made it easy to forget about the lightning in her lungs.
