Answer:

4x² + 4x + 1

Step-by-step explanation:

to evaluate (g ￮ f)(x) , substitute x = f(x) into g(x)

g(f(x))

= g(2x + 1)

= (2x + 1)² ← expand using FOIL

= 4x² + 4x + 1

Answer:

Slope intercept: y = -3/2x + 1

Point slope: y + 2 = -3/2 * (x - 2) [Forgot to add the work for this, I will add it if you need it, feel free to ask.]

Step-by-step explanation:

m = (change in y)/change in x)

But also

m = y_2 - y_1/x_2 - x_1

So lets substitute

m = 1 - (-2)/0 - (2)

Lets find the slope

m = 3/0 - (2)

m = 3/-2

m = -3/2 (Moved the negative)

Now we find the value of b using the equation of a line.

y = mx + b

y = (-3/2) * x + b

y = (-3/2) * (2) + b

-2 = (-3/2) * (2) + b

Now we find the value of b

Lets rewrite

-3/2 * 2 + b = -2

Cancel the CF of 2

-3 + b = -2

Move the terms without b to the right

b = -2 + 3

b = 1

Now we substitute our values of the slope and y-int into y = mx + b to find the equation.

y = -3/2x + 1

Answer:

[tex]y=\frac{-3}{2}x-1[/tex]

Step-by-step explanation:

Given the two points, we can use the slope formula to get the slope of our equation.

[tex]\frac{y_2-y_1}{x_2-x_1}=m[/tex]

Plug in what we know

[tex]\frac{(1)-(-2)}{0-2}=m[/tex]

[tex]m=\frac{-3}{2}[/tex]

[tex]y=\frac{-3}{2}x-b[/tex]

Plug in one of the points given and solve to find our y-intercept [b]

[tex]-2=\frac{-3}{2}(2)-b[/tex]

[tex]b=1[/tex]

(we already know our y-intercept since we're given what y is when x is 0 [hence (0,1)], but this is how it is done if we did not know it initially)

Final equation

[tex]y=\frac{-3}{2}x-1[/tex]

Answer:

Just add the 2 fractions that were mentioned

Step-by-step explanation:

turn 6 1/2 into an improper fraction and then add it to 5/8 by finding a common denominator

so it would be like -

13/2 + 5/8    =      52/8 + 5/8   =   57/8   =   7  1/8

Answer:

6 1/2 + 5/8 = 57/8 = 7 1/8 = 7.125

Step-by-step explanation:

Conversion a mixed number 6 1/2

to a improper fraction: 6 1/2 = 6 1/2 = 6 · 2 + 1/2 = 12 + 1/2 = 13/2

To find a new numerator:

a) Multiply the whole number 6 by the denominator 2. Whole number 6 equally 6 * 2/2 = 12/2

b) Add the answer from previous step 12 to the numerator 1. New numerator is 12 + 1 = 13

c) Write a previous answer (new numerator 13) over the denominator 2.

Six and one half is thirteen halfs

Add: 13/2 + 5/8 = 13 · 4/2 · 4 + 5/8 = 52/8 + 5/8 = 52 + 5/8= 57/8

For adding, subtracting, and comparing fractions, it is suitable to adjust both fractions to a common (equal, identical) denominator. The common denominator you can calculate as the least common multiple of both denominators - LCM(2, 8) = 8. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 2 × 8 = 16. In the following intermediate step, it cannot further simplify the fraction result by canceling.

In other words - thirteen halves plus five-eighths = fifty-seven eighths.

Answer:

26400

Step-by-step explanation:

1 mi=1760 yd

5mi=8800yd

1yd=3ft

8800yd=26400ft

If Heather jogged 5 miles in terms of feet he jogged 26400 feet.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Heather jogged 5 miles.

Also given that 1 mi = 1760 yd and 1 yd = 3 ft.

Therefore, If Heather jogged 5 miles then he jogged 5×1760 yards and

5×1760×3 feet which is,

= 26400 feet.

Answer:

a) odd

b) even

Step-by-step explanation:

a) It is an odd symmetry because it is symmetric about the origin, meaning if you rotate an odd function 180° around the origin, you will have the same function you started with.

b) It is an even symmetry because it reflects over the y-axis. The left and right looks the same.

Answer:

y = 4x - 2

Step-by-step explanation:

slope = (10 - 2)/(3 - 1) = 8/2 = 4

Let the equation be y = 4x + b

Sub (1, 2) into it,

2 = 4*1 + b

so b = 2 - 4 = -2

The equation is y = 4x - 2

Answer:

(Q.1) No solution

(Q.2) True

(Q.3)  x = 4 - 2y

(Q.4) True

Step-by-step explanation:

(Q.1) As shown in the first attached figure.

By graphing.   x + 2y = 8   &   x + 2y = -4

The two lines are parallel, there is no intersection points between the lines.

So, there is no solution to the system of equations.

Also, we should note the parallel lines have the same slope

to find it make the equation similar to y = mx + c where m is the slope

at this situation m = -1/2

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

(Q.2) As shown in the second attached figure.

By graphing the system of inequalities  y> -3x+2  &  y<2x+1

The Shaded area represents the solution of the system of inequalities

And the point (4,2) is inside the shaded area

So, The ordered pair (4,2) is a solution to the system of inequalities.

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

(Q.3) solving the system { x+2y=4  &  2x+2y=6 } by substitution

From the first equation x + 2y = 4

we will find x in terms of y then plug it into the second equation

So, x + 2y = 4 ⇒  x = 4 - 2y

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

(Q.4) As shown in the third attached figure.

By graphing.   2x + 4y = 8  &  x + 2y = 6

The two lines are parallel, there is no intersection points between the lines.

So, there is no solution to the system of equations.

Also, we should note the parallel lines have the same slope

to find it make the equation similar to y = mx + c where m is the slope

at this situation m = -1/2

Answer:

13.5m/s

Step-by-step explanation:

formula is v=u + at

as given:

u=3m/s

a=1.5m/s²

t=7secs

v=3+1.5(7)

v=3 + 10.5

v = 13.5m/s

The unit for velocity is m/s

Answer:

a) 87

b) 13.5

Step-by-step explanation:

for the first question we've been given the equation and the parameters needed

so we just input the parameters

3a+4b when a is 17 and b is 9

therefore the answer is 3*17 + 4*9

51+36=87

second question

that's an equation of motion and we've been given all the parameters we also need so we just input the parameters In the equation

v=u+at

v=3+1.5*7

v= 3+10.5

v=13.5

The value of E(Y) and Var(Y) are 50 and 178/5 respectively

Given the formula for temperature conversion expressed as:

Y = (9/5)*X + 32

where:

X stands for a temperature in degrees Celsius,

Y the same temperature in degrees

If E(X) = 10, then;

Y = (9/5) * 10 + 32

Y = (9*2) + 32

Y = 18 + 32

Y = 50

Hence E(Y) = 50

If Var(X) = 2

Y = (9/5) * 2 + 32

Y = 18/5 + 32

Y =  178/5

Hence Var(Y) = 50

The value of E(Y) and Var(Y) are 50 and 178/5 respectively
