Step-by-step explanation:
Use your knowledge about parentheses and substitution to solve the following:
7. 2(x + 4) + 10 =
8. 3(6x) + 4 =
9. 10(xy) =
10. 5(x + y) =
11. 2(rs) + 4(x)
12. 2(q) + 2(x + t) =
13. 6(7t + 4s) =
14. 9(10x) + 10y =
15. 2x(xy) =
16. r(s)(t) =
17. (r)(s)(t)(x)(y) =
18. (7x + 2Y) =
Answer:
7. 2(x + 4) + 10 =2x+18
8. 3(6x) + 4 = 18x+4
9. 10(xy) = 10xy
10. 5(x + y) =5x+5y
11. 2(rs) + 4(x) = 2(rs+2x)
12. 2(q) + 2(x + t) = 2(q+x+t)
13. 6(7t + 4s) = 42t+24s
14. 9(10x) + 10y = 90x+10y
15. 2x(xy) =2x^2y
16. r(s)(t) =
17. (r)(s)(t)(x)(y) =
18. (7x + 2Y) =

Please help this is worth 15 points! Solve in y=mx+b from!
Answer:
The coordinates of every point on the line will solve the equation if you substitute them in the equation for x and y. The equation of any straight line, called a linear equation, can be written as: y = mx + b, where m is the slope of the line and b is the y-intercept

Stuart wants to find the value of 3 3/4 -2 1/3 Before Stuart can subtract, he needs to rewrite both fractions with a common denominator. Drag a number or expression into each box to show how to write equivalent fractions so the new fractions have a common denominator.
Answer:
1 21/50
Step-by-step explanation:
3 3/4 = (3/4 x 4/4) = 3 9/12
2 1/3 = (1/3 x 3/3) = 2 4/12
3 9/12 - 2 4/12 = 1 21/50

PLS ANSWER ASAP
A ball is projected upward from ground level with an initial velocity of 80 feet per second. After how many seconds will it be at a height of 96 feet? Use the velocity formula.
A ball is dropped from the top of a 400-ft tall tower. The relationship between the time, t, in seconds, and the height, h(t), in feet, of the ball can be modeled by a quadratic function. Specific values of the function are shown in the table below
Part A: Determine the average rate of change of h(t) between t = 2 and t = 5.
Part B:Explain what this average rate of change means in terms of the context.

6) Write a system of linear inequalities that is given by the following graph.
Answer:
The system of inequalities are x - y < 1 and y < - 2 The horizontal line shown in the graph has equation y = - 2 {As it is parallel to x-axis} Now, this line is dotted and the lower portion of the graph is shaded. So, the inequality will be y < - 2 ......... (1) Again, another line is there in the graph which passes through the points (1,0) and (0,-1)So, its equation will be
⇒ y + 1 = x ⇒ x - y = 1 Now, the origin (0,0) is within shaded zone of the inequality and putting x = 0 and y = 0, we get 0 - 0 < 1 So, the equation of the inequality is x - y < 1 {As the line is dotted} Therefore, the system of inequalities are x - y < 1 and y < - 2 (Answer)
Step-by-step explanation:
A student uses the figure below to find the measure of Angle S. The student first finds the measure of angle P. Why does finding the measure of angle P help the student find the measure of angle S?
answer choices
Angle P and Angle S are ADJACENT angles and ADD UP TO 180 degrees.
Angle P and Angle S are VERTICAL angles and ADD UP TO 90 degrees.
Angle P and Angle S are ADJACENT angles and are EQUAL.
Angle P and Angle S are VERTICAL angles and they are EQUAL
Answer:
I could be wrong, but here is what I think.
Angle P and Angle S are ADJACENT angles and are EQUAL.
Step-by-step explanation:
It is currently 0 degrees outside, and the temperature is dropping 4 degrees every hour. The temperature after h hours is -4h<-14. Find 2 possible answers for h that make the inequality true.

C. 2 hours
D. 4 hours
E. 4 hours
Simplify the fraction below.
35/4
Answer:
8 3/4
Step-by-step explanation:
find the greatest common factor of 35 and 4, which is 1. Then divide both 35 and 4 by the greatest common factor to get the following simplified fraction: 35/4
If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. You could convert it into a whole number or mixed number fraction. Which would now be 8 3/4
