The solution of the given inequality.

Solution:

We have,

[tex]-2x+2>3x-8[/tex]

Isolate the variables terms on the left side.

[tex]-2x-3x>-2-8[/tex]

[tex]-5x>-10[/tex]

Divide both sides by -5 and change the inequality sign as we divide the equality by a negative value.

If m∠4 = 131°, find each given angle measure. Justify your answer.

a. m∠8 =


b. m∠5


c. m∠2


d. m∠1


e. m∠6


f. m∠7

Answers

Answer/Step-by-step explanation:

Given:

m<4 = 131°

a. m<8 = 180 - m<4 (linear pair)

m<8 = 180 - 131 (substitution)

m<8 = 49°

b. m<5 = m<4 (alternate exterior angle are congruent)

m<5 = 131° (substitution)

c. m<2 = m<5 (vertical angles are congruent)

m<2 = 131° (substitution)

d. m<1 = m<8 (vertical angles are congruent)

m<1 = 49° (substitution)

e. m<6 = m<1 (vertical angles are congruent)

m<6 = 49° (substitution)

f. m<7 = m<4 (vertical angles are congruent)

m<7 = 131° (substitution)

The length of two sides of a right triangle are leg: 9 m and hypotenuse: 15 m. Find the length of the third side.

Answers

Answer:

Length of Third Side = 12 m

Step-by-step explanation:

You can use the Pythagorean Theorem to solve this: a² + b² = c² or c² - b² = a² in which a and b are legs, and c is the hypotenuse. We use the second equation to solve this: 15² - 9² = a² or 225 - 81 = a². This simplifies to 144 = a². To find a specifically, find the square root of 144, 12.

April, x, slept 9 hours; Evelyn slept 2/3
less than that.
Evelyn slept _______________ hours. Write the equation as both a decimal and fraction.

Answers

Answer:

she slept for 3 hours

Step-by-step explanation:

its actually simple so we know that April slept for 9 hours bug Evelyn only slept 2/3 of 9 hours and if you add 1/3 and 2/3 you get 3/3 which equals a whole so all you have to do is devide 9 into 3 and you get 3 parts with 3 now you add 3 and 3 together and that equals 6 and that was two parts you added which is equaled to 2/3 so all you have to do now is subtract 9-6 and you leave with three which is 1/3 so we come to the final answer she slept for three hours

Answer:

g has an average rate of change of zero at the intervals [-5,4] and [-2,2]

Step-by-step explanation:

When we talk of the average rate of change, we mean the change in y values divided by the change in x values

Once the change in y-values is zero, then over that interval, the average rate of change is zero

at the point t =- 5, g(t) = 6; at the point t = 4, g(t) = 6

As we can see here, within the interval [-5,4]; the average rate of change is 0

This same pattern is repetitive at points or ranges where we have same values for g(t)

Somebody pls!! “Write the equation of the line in fully simplified slope-
intercept form.”

Answers

Answer:

y = 3/5x + 5

Step-by-step explanation:

Slope-intercept form is y = mx + b where m is the slope (rise / run of the line) and b is y-intercept (y value of where the line intersects with the y-axis.

The line is rising up 3 and run to the right 5 and so it's slope is 3/5. The line intersects with the y-axis at a y value of 5 and so it's y-intercept is 5.

Therefore, your answer in slope-intercept form is y = 3/5x + 5.
