[tex]f(x) = 1 - 2 x ^{2} [/tex]
[tex]g(x) = x + 1[/tex]
Compute f(g(-1)).
Step-by-step explanation:
f(g(x))= f(x+1)
f(g(1))= f(-1+1)= f(0)
f(0)= 1 - 2(0)²
=1-0
=1

9x+10=11x-10
Please show work
Answer:
[tex]x=10[/tex]
Step-by-step explanation:
1) Subtract 10 from both sides of the equation
[tex]9x+10=11x-10\\9x+10-10=11x-10-10[/tex]
2) Simplify
a. Subtract the numbers
b. Subtract the numbers again
[tex]9x=11x-20[/tex]
3) Subtract 11x from both sides of the equation
[tex]9x=11x-20\\9x-11=11x-20-11x[/tex]
4) Simplify
a. Combine like terms
b. Combine like terms again
[tex]-2x=-20[/tex]
5) Divide both sides of the equation by the same term
[tex]-2x=20\\\frac{-2x}{-2} =\frac{-20}{-2}[/tex]
6) Simplify
a. Cancel terms that are in both the numerator and denominator
[tex]\frac{-2x}{-2} =\frac{-20}{-2} \\x=\frac{-20}{2}[/tex]
b. Divide the numbers
[tex]x=\frac{-20}{-2x} \\x=10[/tex]
The figure is cut into 6 equal pieces. Shade 2/3 of the figure.
Answer:
2/3 = 1/3 + 1/3 = 4/6
shade 4 of the equal parts.
Answer:
Shade 4/6 pieces of it
Step-by-step explanation:
2 out of 3 x 2 so it can fit 6 would be 4 out of 6. Basically shade half of it plus a third and that's your answer :)
Find the x and y intercepts
Answer:
Below
Step-by-step explanation:
The x-intercepts are the points on the graph where the lines cross the x-axis. This means that whatever the x-intercepts points are, the y's will be 0 :
(-3,0) and (3,0)
The y-intercept is the point on the graph where the line crosses the y-axis. This means that whatever the y-intercept point is, the x's will be 0 :
(0,-3)

Which is the image of the point (9,-4) after a reflection about line y = 2 then translated along the vector <-2,4>?
A. (7,4)
B. (9,8)
C. (7,0)
D. (7,12)
=======================================================
Explanation:
Start at (9,-4). Move 6 units up to arrive at (9,2). This second point is on the horizontal mirror line of y = 2. We move another 6 units to get to (9,8).
Going from (9,-4) to (9,8) represents reflecting over the line y = 2.
Now apply the translation vector <-2,4> which says "shift to the left 2 units and shift up 4 units". That translation vector is the same as writing the rule [tex](x,y) \to (x-2,y+4)[/tex]
Applying that translation to the point (9,8) moves us to (7,12)

How can you tell if an equation (for example, x=16+3y (don’t solve this)) will be represented by a straight line when graphed on a coordinate plane? Is there an easy way to tell or how do you figure that out?
Answer:
I know it is a straight line because I can convert it into standard or slope intercept form. An example of when something isn't a straight line is like y=|x|.
x=16+3y
-3y=-x+16
y=1/3x-16/3
If two lines intersect each other, then the vertically opposite angles are equal
Answer:
True
Step-by-step explanation:
Theorem 6.1 : If two lines intersect each other, then the vertically opposite angles are equal. In the statement above, it is given that 'two lines intersect each other'. ... They lead to two pairs of vertically opposite angles, namely, (i) ∠ AOC and ∠ BOD (ii) ∠ AOD and ∠ BOC.

please answer this and explain I'm having a hard time understanding this
Answer:
Step-by-step explanation:
Statement
1 .
m<ACB = 2(x+10)
m <DCE = 5(3x-74)
2. <ABC ≅ <DCE
3. <ABC = <DCE
4. 2(x+10) = 5(3x-74)
5. 2x+20 = 15x -370
6. -13x = -390
7. x = 30
8. m<ACB = 2(30+10)°
9. m<ACB =80
Reason
1. Given
2. Vertical angles are congruent
3. Congruent angles have equal measure
4. Substitution POE (postulate of equivalence)
5. Distributive property of multiplication over addition and subtraction
6. - POE (subtraction POE- because we subtracted the same amount from both sides of the equation 15x and 20 )
7. division POE (we divided both sides of the equation by -13)
8. Substitution Postulate (we substituted x for 30)
9. Addition and multiplication postulate

Factor -4 out of -12r + 20.
Answer:-12r+20=-4(3r-5)
Step-by-step explanation:
Pls mark as brainliest
Answer:
-4(3r + 5)
Step-by-step explanation:
To factor -4 out of -12r + 20, we need to find out what are the factors that can be multiplied with -4 to get a product of -12r and 20.
To get a product of -12, we must multiply -4 by 3r.
And to get a product of 20, we must multiply -4 by -5.
Therefore, the correct answer is: -4(3r - 5)

Which equation shows that the product of a square matrix A and its identity matrix I is A?
Answer:
Option B
Step-by-step explanation:
The multiplication process of matrices works by multiplying the first row of the first matrix by the first column of the second matrix. The same goes with the second row of the first matrix by the second column of the other matrix. Below is the solution why option B is the correct answer.
[tex]A = \left[\begin{array}{ccc}8&11\\13&5\\\end{array}\right][/tex]
[tex]B = \left[\begin{array}{ccc}1&0\\0&1\\\end{array}\right][/tex] ← This is the Identity Matrix.
The attached screenshot shows the solution of the multiplication process. In essence, if you multiply any matrix by the identity (Matrix B), you should end up with your original matrix. Thus, multiplying Matrix A by the Identity matrix results in the same values as Matrix A.
Therefore, the correct answer is B.
