Answer:

Step-by-step explanation:

What they are asking for here is where the y-values are negative in interval format. Intervals are x things only, no y's allowed. So the interval of (-infinity, -3) indicates an x value of negative infinity to an x value of -3. The y's are negative from an x value of negative infinity to an x-value of -3, then again from an x value of almost -1 to an x value of almost positive 1. So your choice is the last one listed there.

(xy)^2

Step-by-step explanation:

Answer:

f (x) + b shifts the function b units upward.

f (x) – b shifts the function b units downward.

f (x + b) shifts the function b units to the left.

f (x – b) shifts the function b units to the right.

–f (x) reflects the function in the x-axis (that is, upside-down).

Step-by-step explanation:

Step 1: Take 20 and multiply by 0.75 to get the number of answers that were correct, which is 15.

Step 2: Put the number of correct questions and the total number of questions into a ratio form, 20:15

Answer:Answer/Step-by-step explanation:

Given that m<3 = 54°

a. <1, <2, and <3 are angles on a straight line. They add up to 180°.

m<3 is given as 54°, m<2 = 90°, therefore,

m<1 = 180 - (54 + 90) = 180 - 144

m<1 = 36°

b. <2 is indicated as a right angle. Therefore, m<2 = 90°

c. <1 and <4 are vertical opposite angles. Vertical angles are congruent, since m<1 = 36°, therefore, m<4 = 36°

d. <5 and <2 are vertical opposite angles. m<2 = m<5, therefore, m<5 = 90°

e. <6 and <3 are vertical opposite angles. m<3 = m<6, therefore, m<6 = 54°

f. m<7 + m<6 = 180° (same side interior angles are supplementary)

m<7 = 180 - m<6

m<7 = 180 - 54

m<7 = 126°

g. m<7 + m<8 = 180° (linear pair)

126° + m<8 = 180

m<8 = 180 - 126

m<8 = 54°

h. m<9 = 180 - m<8 (linear pair)

m<9 = 180 - 54

m<9 = 126°

i. m<10 = m<8 (vertical angles)

m<10 = 54°

j. m<11 = m<4 (alternate interior angles are congruent)

m<11 = 36°

k. m<12 = 180 - m<11 (linear pair)

m<12 = 180 - 36

m<12 = 144°

l. m<13 = m<11 (vertical angles)

m<13 = 36°

m. m<14 = m<12 (vertical angles)

m<14 = 144°

Step-by-step explanation:

Answer:

A. M<1 = 36°

B. M<2= 90°

C. M<4= 36°

D. M<5= 54°

E. M<6= 54°

F. M<7= 126°

G. M<8= 54°

H. M<9= 126°

I. M<10 = 54°

J. M<11 = 36°

K. M<12 = 144°

L. M<13= 36°

M. M<14 = 144°

Answer:

[tex]x^{2} +2x-15 = 0[/tex]

Step-by-step explanation:

x = 3 and x = -5

(x - 3) = 0 and (x + 5) = 0

(x - 3) * (x + 5) = 0

[tex]x^{2} + 5x - 3x - 3*5 = 0\\x^{2} +2x-15 = 0[/tex]

Step-by-step explanation:

Two hot air balloons.

Balloon one: starts at 30 miles from town and after 2 hours, it is 48 miles

Distance of Tasha's balloon is represented by function y = 8x + 20

x is independent variable so it would represent the time.

y is dependent so it represents the miles travelled.

Balloon one = (0, 30) <-- begins here and (2, 48)

Balloon two = (0, 20).

So balloon one began at 30 miles while tasha's balloon began at 20 miles from town.

So Henry's balloon was farther form the town at the beginning.

Now let's find the slope/rate of change and compare then.

Henry's balloon: y-y1/x-x1 = 48-30/2 = 18/2 = 9

Tasha's balloon m: 8

9>8 Therefore henry was faster

Given the equation

[tex]5x-3=5[/tex]

MaReeco's rewrote equation is given by

[tex]5x = 2[/tex]

As MaReeco subtracted 3 to the right side of the equation, which imbalanced the equation. Hence, it is not correct.

Correction:

For the next step, MaReeco should have added 3 to both sides

i.e.

[tex]5x-3+3=5+3[/tex]

[tex]5x=8[/tex]

Therefore, the acceptable move would have been:

Answer:

130

Step-by-step explanation:

First you want to start in the one's place in 10000010, multiply the ones place with 2^0

then move to the left to the tens place with 2^1

hundreds place with 2^2 an so on

Decimal equivalent of "0" = 0 × 2^0 = 0

Decimal equivalent of "1" = 1 × 2^1 = 2

Decimal equivalent of "0" = 0 × 2^2 = 0

Decimal equivalent of "0" = 0 × 2^3 = 0

Decimal equivalent of "0" = 0 × 2^4 = 0

Decimal equivalent of "0" = 0 × 2^5 = 0

Decimal equivalent of "0" = 0 × 2^6 = 0

Decimal equivalent of "1" = 1 × 2^7 = 128

Next you want to add all the products you just got to get the decimal equivalent of 10000010

0 + 2 + 0 + 0 + 0 + 0 + 0 + 128 = 130

Therefore the binary number 10000010 in decimal is 130
