Answer 1

Step-by-step explanation:

8x + y = -16

y = -8x - 16 --(1)

-3x + y = -5 --(2)

sub (1) into (2):

-3x - 8x - 16 = -5

-11x = 11

x = -1

sub x = -1 into (1):

y = -8(-1) - 16

y = -8

therefore, the solution is (-1, -8).

Answer:

∠EGA = 123°

∠EHD = 57°

Step-by-step explanation:

Determine the measure of ∠EGA:

Since ∠EGB and ∠EGA make up the angle of a straight line (180°):

∠EGB+∠EGA = 180

57+∠EGA = 180 (given that ∠EGB = 57°)

∠EGA = 123°

Determine the measure of ∠EHD:

∠EHD = ∠EGB (corresponding angles of parallel lines are equal)

∠EHD = 57° (given that ∠EGB = 57°)

what is what3 2/3 + 3/5 as a fraction brainly

Answers

have u tried socratic

Answer:

It is 4 4/15

Step-by-step explanation:

We convert 2/3 and 3/5 to fifteenths because we cant add numbers with different denominators.

2/3 = 10/15  |  3/5 = 9/15

10/15 + 9/15 = 19/15 = 1 4/15. Then, we add the 3.

3 + 1 4/15 = 4  4/15.

Two radio stations are playing the #1 hit song "2 Nice 2 B True" by Anita and the Goody-2-Shoes. WMTH plays the song every 12 minutes. WMSU plays the song every 8 minutes. Both stations play the song at 3:00 P.M. When is the next time the stations will play the song at the same time?

Answers

Answer:

03:24 PM

Step-by-step explanation:

Given

[tex]Start\ Time = 3:00PM[/tex]

WMTH = Every 12 minutes

WMSU = Every 8 minutes

Required

Determine when they both play the song

To do this, we simply solve for the LCM of 8 and 12

List the factors of 8 and 12

[tex]8 : 8, 16, 24...[/tex]

[tex]12: 12, 24, 36...[/tex]

From the above, the least common multiple is 24

This means that the song will be played on both stations 24 minutes after 3:00PM

In other words, 03:24 PM

Simplify the expression: 18.1 - 1.1(7.4 - 9.6 + 0.5) please show your work!

Answers

Answer:

19.97

Step-by-step explanation:

18.1 - 1.1 x (7.4 - 9.6 + 0.5)

18.1 - 1.1 x (-2.2 + 0.5)

18.1 - 1.1 x (-1.7)

18.1 + (1.87)

19.97

The simplified value of the expression 18.1 - 1.1(7.4 - 9.6 + 0.5) is 36.8.

What is a numerical expression?

A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.

Given, An expression  18.1 - 1.1(7.4 - 9.6 + 0.5).

let us multiply each term of the expression to remove the decimal.

∴ 181 - 11(74 - 96 + 5).

= 181 - 11(-17).

= 181 + 187.

= 368 but the actual answer is 36.8 as we have to divide by 10.

which expression is equivalent to 2cos2(x/2)-cos(x)

Answers

The expression that is equivalent to 2cos²(x/2) - cos(x) is 1.

What are trigonometric equations?

These are the equation that contains trigonometric operators such as sin, cos.. etc.. In algebraic operations.

Here,
We can use the double angle identity for cosine, which states that:

cos(2θ) = 2cos²(θ) - 1

To simplify given expression expression by putting cos(x) = 2cos²(x/2) - 1 as follows:

= 2cos²(x/2) - cos(x)

= 2cos²(x/2) - 2cos²(x/2) + 1  (using the identity cos(2θ) = 2cos²(θ) - 1)

= 1

Therefore, the expression that is equivalent to 2cos²(x/2) - cos(x) is 1.

Solve the inequality 5x – 7 > 4x + 8

Answers

Answer:

x > 15

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDASEquality Properties

Step-by-step explanation:

Step 1: Define inequality

5x - 7 > 4x + 8

Step 2: Solve for x

Subtract 4x on both sides:                    x - 7 > 8Add 7 on both sides:                             x > 15

Here we see that any value x that is greater than 15 would work as a solution to this inequality.

b) Work out the rate of change between 8 seconds and 12 seconds.

Answers

Answer:

a. 37.5

b. 25

Step-by-step explanation:

a. Rate of change the first 4 seconds can be calculated using the points (0, 0) and (4, 150):

Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{150 - 0}{4 - 0} = \frac{150}{4} = 37.5 [/tex]

b. Rate of change between 8 seconds and 12 seconds using the points (8, 150) and (12, 250):

Rate of change = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{250 - 150}{12 - 8} = \frac{100}{4} = 25 [/tex]

cuanto es la Raiz cuadrada de 12​

Answers

la raíz cuadrase es 3.464

The square root of 12 is approximately 3.4641.

The square root of 12 is an irrational number, meaning it cannot be expressed as a fraction or terminating decimal. However, we can approximate its value.

To approximate the square root of 12, we can use a calculator or perform an estimation. The square root of 12 is approximately 3.4641.

When we multiply 3.4641 by itself (3.4641 * 3.4641), we get a value very close to 12, but not exactly 12 due to the irrational nature of the square root.

The square root of 12 represents a number that, when multiplied by itself, equals 12. It is a non-repeating, non-terminating decimal that goes on infinitely. The approximation 3.4641 is commonly used to represent the square root of 12 in practical calculations.
