Answer:
x = 11(13/14)
Step-by-step explanation:
3/5(x – 7/10) = -31/4
open the bracket:
3/5 * x – 7/10 = -31/4
3/5 * –7x/10 = -31/4
3/5 + 31/4 = 7x/10
(12+155)/20 = 7x/10
167/20 = 7x/10
cross multiply:
140x = 1670
x =1670/140
x = 11(130/140)
x = 11(13/14)
The value of x is 1/5.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
3/5 (x − 7/10)= −3 1/4
Now, Solving for x
3/5 ( x- 7/10 )= 13/4
x- 7/10 = -13/4 x 5/3
x- 7/10 = -65 /12
x= -65/12 + 7/10
x= 24/ 120
x= 1/5
hence, the value of x is 1/5.

Y = 1/2x + 2
Step-by-step explanation:
First you find (b) or the Y-intercept which is 2 (Y = mx + 2)
Then you do rise over run to find slope. Rise = 1. Run = 2. Slope (m) = 1/2
Now you have your answer Y = 1/2x + 2

Tina was observing the changing heights of a ball as it bounced over time. She graphed the function on this coordinate grid to show f(x), the height of the dropped ball, in feet, after its xth bounce.
Part A: What is f(3)? Explain what this value represents in the given context.
Part B: Tina said that a possible range for the given function is y > 0. Based on the given scenario, do you agree or disagree? If you agree, explain why the range is correct. If you disagree, what values should be the range for the given scenario?
The range for the given scenario is y≥0.
Given that, Tina graphed the function on the coordinate grid to show f(x), the height of the dropped ball, in feet, after its xth bounce.
What is the function?Functions are the fundamental part of the calculus in mathematics. The functions are the special types of relations. A function in math is visualized as a rule, which gives a unique output for every input x.
Part A:
From the graph we can see that, for f(3) that is for 3 bounces the height is 4 feet.
Part B: Tina said that a possible range for the given function is y > 0.
From the graph we can see that for f(7) and f(8), the ball is almost at rest position. So the range can be y≥0.
Therefore, the range for the given scenario is y≥0.

The X is equal to 1.75
Step-by-step explanation:
3.5X2.25=7.875
14/7.875=1.75
Answer: x=1.75
Step-by-step explanation:
rearrange the term: 3.5 (2.25 + x) = 14
the new term: 3.5 (x + 2.25) = 14
Combine multiplied terms into a single fraction, then distribute.
x = 1.75
evaluate this expression when c= -2 and d= 2:
Step-by-step explanation:
you just have to put the given values in place of the variable names and then simply calculate.
(-2² + 2²) - 2(-2² - 2²) = (4 + 4) - 2(4 - 4) = 8 - 2×0 = 8
so, B is the right answer.
please remember the correct sequence of operations :
first are brackets.
then exponents.
then multiplications and divisions.
and then (at last) additions and subtractions.
and also please remember : multiplying a negative number with a negative number creates a positive result.
that is of course also true for squaring a negative number, as ² just means that the negative number is multiplied with itself.
now you also know the result of -2³, right ?
as this means -2 is multiplied 3 times by itself. what does that do to the sign ?
-2 × -2 = 4 (positive).
but now we have to multiply a third time
4 × -2 = -8 (because multiplying a positive number with a negative number creates a negative result).

Answer:
B, C
Step-by-step explanation:
2(8y+1/2) would be equal to 2x8y+2x1/2=16y+1.
2(8y+1/2) would also be equal to 8y+1/2+8y+1/2 because multiplying by 2 is basically just adding the thing you are multiplying to itself.
