Answer:
- 46
Step-by-step explanation:
evaluate g(- 2) then substitute the result into f(x) , that is
g(- 2) = (- 2)² + 5 = 4 + 5 = 9 , then
f(9) = - 5(9) - 1 = - 45 - 1 = - 46

Answer:
x = 13°
Step-by-step explanation:
The left base angle of the triangle with x as the vertex is vertically opposite 85° and are congruent.
left base angle = 85°
the angle below the right base in the triangle is corresponding to 98° and are congruent.
right base angle = 180° - 98° = 82° ( adjacent angles on a straight line ) , then
x = 180° - (85 + 82)° = 180° - 167° = 13° ( sum of angles in a triangle )

and evaluate an expression to determine how much Jill owes Mr. James.
Answer:
512
Solution:
so first you multiply 15 times 32 and get 480 than you add 32 and get 512.

Is (x-3) a factor of (x3 - 3x2 + 2x + 2)?
SHOW FULL WORK
Answer:
No
Step-by-step explanation:
If (x - 3) is a factor then x = 3 is a root and the polynomial will equal zero for x = 3 , that is
3³ - 3(3)² + 2(3) + 2
= 27 - 3(9) + 6 + 2
= 27 - 27 + 8
= 8
since the polynomial ≠ 0 for x = 3 then (x - 3) is not a factor

What is the equation of the line that is parallel to the given line and passes through the point (2, 3)? x 2y = 4 x 2y = 8 2x y = 4 2x y = 8.
The equation of the line that is parallel to the given line and passes through the point (2, 3) is,
[tex]x+2y=8[/tex]
What is the equation of line?The equation of the line is the way of representation of a line in the equation form.
The equitation of the lines represents the line by the set of points on which the line lies or passes through in the coordinate system.
Given information-
The points through which the line passes is (2, 3).
The points of the line shown in the image attached below is (-4, 0) and (4, -4).
The slope of the line shown in the image which passes through the point (-4, 0) and (4, -4) is,
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{-4-0}{4-(-4)}\\m=\dfrac{-4}{8}\\m=\dfrac{-1}{2}[/tex]
As the line which passes through the point (2, 3) is parallel to the line shown below. Hence, the slope of it must be equal to that line.
Therefore the equation of the line which passes through the point (2, 3) and has a slope of -1/2, is,
[tex](y-y_1)=m(x-x_1)\\(y-3)=-\dfrac{1}{2}(x-2)\\2(y-3)=-x+2\\2y-6=-x+2\\x+2y=8[/tex]
Thus the equation of the line that is parallel to the given line and passes through the point (2, 3) is,
[tex]x+2y=8[/tex]
Hence, the option 2 is the correct option.

Which is the equation of a hyperbola with directrices at x = ±3 and foci at (4, 0) and (−4, 0)?
Answer:
[tex]\frac{x^2}{12}-\frac{y^2}{4}=1[/tex]
Step-by-step explanation:
Since our foci are located on the x-axis, then our major axis is going to be the horizontal transverse axis of the hyperbola:
Formula for hyperbola with horizontal transverse axis centered at origin
[tex]\frac{x^2}{a^2}-\frac{y^2}{b^2}=1[/tex]Directrices -> [tex]x=\pm\frac{a^2}{c}[/tex]Foci -> [tex](\pm c,0)[/tex] where [tex]a^2+b^2=c^2[/tex][tex]a>b[/tex]Since we are given our directrices of [tex]x=\pm3[/tex] and foci of [tex](\pm4,0)[/tex], then we can set up the directrices equation to solve for [tex]a^2[/tex]:
[tex]x=\pm\frac{a^2}{c}\\ \\\pm3=\pm\frac{a^2}{4}\\ \\12=a^2[/tex]
Now we can determine [tex]b^2[/tex] to complete our equation for the hyperbola:
[tex]a^2+b^2=c^2\\\\12+b^2=4^2\\\\12+b^2=16\\\\b^2=4[/tex]
Therefore, our equation for our hyperbola is [tex]\frac{x^2}{12}-\frac{y^2}{4}=1[/tex]

faster than his time in 2008.
Step-by-step explanation:
5a- rounding to nearest 10th 9.683 = 9.7
rounding to nearest 10th 9.572 = 9.6 both times are not same so false

please help me find the total surface area
Answer:
Area of the figure = 64 cm²
Step-by-step explanation:
To find the total surface area (TSA) of the figure, we must add the areas of the 4 triangles along with the area of the square.
Given,
Altitude of triangle (h) = 6 cmBase of triangle (b) = 4 cmSide of the square (h) = 4 cmBy using these values,
Area of the triangle = ½ bhArea of the triangle = ½ × 6 × 4Area of the triangle = ½ × 24Area of the triangle = 12 cm²Now,
Area of the square = s²Area of the square = 4²Area of the square = 16 cm²So, from this,
Area of the figure = (4 × Area of the triangle) + Area of the square Area of the figure = (4 × 12) + 16Area of the figure = (48) + 16Area of the figure = 64 cm²•°• The TSA of the figure is 64 cm².

Find the mZMNI.
M
15x – 12
L
6x
12x+2
N I
Step-by-step explanation:
sum of two interior angles is equal one exterior angle....this implies that,
6x + 15x-12 = 19x+2.....make X the subject
6x+15x-19x = 2+12
2x = 14..... divide both sides by 2
x = 7
this implies that, 19x + 2 where x is 7,
= 19(7) +2
=135°
therefore,<MNI = 135°
The angle MNI is 135 degree.
What is angle?An angle is the figure formed when two rays cross at a common endpoint, according to the definition of angles.
The name of an interior angle of a triangle that is not adjacent to a given exterior angle of the triangle is remote Interior Angle.
Sum of two interior angles is equal one exterior angle.
Here:
(6 x) + (15 x-12) = (19 x+2)
6 x + 15 x - 19 x = 2 + 12
6 x - 4 x = 14
2 x = 14, x =7
Putting the value of x in (19 x + 2).
19 * 7 + 2 = 133 + 2 = 135.
Therefore, the value of 19 x + 2 is 135 degree.

Which of the following is an irrational number?
How do I solve this using Substitution??
Answer:
-1
Step-by-step explanation:
so -x-6 and x-4 are both = to y so that means they are both = to each
other so -x-6=x-4 add x to both sides -6=2x-4 add 4 to both sides 2x = -2 simplify by divide by 2 so x=-1
Answer:
Take the second equation and add 4 to both sides, this gives you x=y+4. The plug in y+4 on the first equation, so y=-(y+4)-6, distribute the negative to everything inside the parentheses, and you get y=-y-4-6. Combine like terms and you get y=-y-10, then add y to both sides, you get 2y=-10, divide both sides by 2 and you get y=-5.
Then plug -5 into the second equation and you get -5=x-4, add 4 to both sides and you get -1=x.
If you want to check your answer, just plug in x and y to either of the equations and see if it makes a true statement.
