Answer:
v=3
Step-by-step explanation:
First you must use the distributive property to solve for v. To do this multiply ever term in the parentheses by -5 on the right-hand side to get -110=-5-35v
Now you can solve by adding 5 to both sides, cancelling out the -5 on the right-hand side of the equation and getting -105=-35v. Now, all you have to do is divide both sides by -35 and get 3=v.
Answer:
v = 3
Step-by-step explanation:
-110 = -5(1 + 7v)
-110 = -5 + -35v
-110 + 5 = -35v
-105 = -35v
Divide both sides of the equation by -35 so v can stand alone
[tex]\frac{-105}{-35} = \frac{-35v}{-35}[/tex]
3 = v
∴v = 3

Answer:
C. It has been stretched horizontally.
Step-by-step explanation:
According to the diagram, the parabola has not been reflected in any way, nor has it been translated, since the parabola is pointing up in a smile, and the vertex is still at the origin.
The parabola does appear to be stretched, since the parent function had points at (1, 1), and (2, 4), but this parabola does not contain those points.
Since the parabola appears to be flatter than the parent function, we can say that C. It has been stretched horizontally.

FIRST ANSWER BRAINLEST!!!! The two top NBA players played a basketball game against the RSM team. Together the NBA players made 85 baskets, scoring one point for free throws and two or three points for field goals. They scored a total of 184 points during the game. If they made 22 free throws, how many three-point field goals did they make.
Answer:
They made 36 three-point field goals
Step-by-step explanation:
For free throws , we have one point each.
So here, the total points they made from free throws is 22 * 1 = 22 points
So the number of points made from field goals would be 184-22 = 162 points
So the issue we have now is knowing the number of 3-point field goals that was made.
How can we get this?
Remember they made 85 baskets? so if we subtract the number of free throws, then we can have the number of field throws and that is 85-22 = 63
Now, let the number of 2 points throws be x and the number of 3 points throws be y
From our earlier analysis;
x + y = 63 ••••••••• (i)
Now the total number of three pointers would be 3 * y = 3y and the total number of two pointers would be 2 * x = 2x
Adding both gives a total of 162
Thus;
2x + 3y = 162 •••••••• (ii)
So we have two equations to solve simultaneously.
From equation 1, we can say that;
x = 63-y
Let’s substitute this into equation 2
2(63-y) + 3y = 162
126 -2y + 3y = 162
126+y = 162
y = 162-126
y = 36
This means that they made 36 three-point field goals
A new pair of sunglasses is regularly priced at $130.00. What
will the price be after at 35% discount? *
Answer:
$ 84.50
Step-by-step explanation:
Regular price = $130
Discount = 35% of 130
= [tex]\frac{35}{100}*130[/tex]
= 0.35 * 130
= $ 45.50
Price of the sunglasses after discount = Regular price - discount
= 130 - 45.50

• A research scientist measures the outside temperature, in degrees Fahrenheit, at various
times throughout a 24-hour period and records her findings in the graph below. In this
real-world function, the hours represent the input values, and the temperature represents
the output values. Use the graph to identify the range of the function. Write your answers
using set notation. Then write a sentence to explain what the range represents in
this function
Answer:
{t|60 <= t <= 85}
Step-by-step explanation:
The temperatures were measures at different times, but does not stop the values being real numbers (i.e. not discrete, or integer values).
So the range of the function is the set of all values between the minimum and maximum measured during the measuring interval (domain) of hours two and twenty-two.
The minimum value = 60F
The maximum value = 85F
So the interval of the range is [60,85], in interval notation.
In set-builder notation, it is
{t|60 <= t <= 85}

b) The product of two positive numbers is 56. If their difference is 10, find the
numbers
Answer:
14 and 4
Step-by-step explanation:
xy = 56
x - y = 10
x = 10 + y
(10+y)y = 56
10y + y² = 56
y² + 10y - 56 = 0
(y-4)(y+14) = 0
y - 4 = 0
y = 4
y + 14 = 0
y = -14
y is a positive integer so y = 4.
x - 4 = 10
x = 14
The two numbers whose product is 56 and difference is 10 are 14 and 4
A = 14
B = 4
What is an 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.
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 data ,
Let the first number be = A
Let the second number be = B
The product of two numbers is = A x B
The difference of two numbers is = A - B
Now , the equation is
A x B = 56
A - B = 10
Now ,
( A - B )² = A² + B² - 2 ( A x B )
Substituting the values of A and B in the equation , we get
100 = A² + B² - 112
Adding 112 on both sides , we get
A² + B² = 212
When A = 14
B² = 212 - 196
B² = 16
So , B = 4
Therefore , the value of A is 14 and value of B is 4
Hence , The two numbers whose product is 56 and the difference is 10 are 14 and 4

Angle ABC is bisected by line segment AD. If angle ABC measures 108° and one of the smaller angles created by line AD measures (5x+4), what is the value of x?
Answer:
x = 10
Step-by-step explanation:
One of the smaller angles that is created by the angle bisector measures 5x+4.
An angle bisector cuts an angle into two equal parts. So, 5x+4 = 1/2 (108) or
2(5x+4)=108 (divide both sides by 1/2)
10x+8=108 (distribute)
10x=100 (subtract 8 from both sides)
x=10 (divide by 10)
x=10

find the value of a and b for which the system of equations has infinitely many solutions : 2x + 3y = 7 ; (a-b)x + (a+b)y = 3a + b - 2
Answer:
a= 5 and b=1
Step-by-step explanation:
To solve, we will follow the steps below:
2x + 3y = 7
(a-b)x + (a+b)y = 3a + b - 2
We should note that since it has infinitely many solutions then,
[tex]\frac{a_{1} }{a_{2} } = \frac{b_{1} }{b_{2} } = \frac{c_{1} }{c_{2} }[/tex]
Hence
2/a-b = 3/a+b = 7/3a +b-2
2/a-b = 3/a+b
cross-multiply
3(a-b) = 2( a+b)
open the bracket
3a - 3b = 2a + 2b
collect like term
3a - 2a = 2b + 3b
a = 5b -------------------------------------------(1)
Similarly
3/a+b = 7/3a +b-2
cross-multiply
7(a+b) = 3(3a+b -2)
7a + 7b = 9a + 3b -6
take all the variables to the left-hand side of the equation
7a - 9a+ 7b-3b = -6
-2a + 4b = -6 ---------------------------------(2)
but a = 5b
substitute a= 5b in equation (2) and solve for b
-2(5) + 4b = -6
-10 + 4b = -6
add 10 to both-side of the equation
-10 + 10+ 4b = -6+10
4b = 4
divide both-side of the equation by 4
b = 1
substitute b= 1 in equation (1)
a = 5b
a =5(1)
a=5
Therefore, a= 5 and b=1

A triangle has side lengths of 200 units and 300 units. Write a compound inequality for the range of the possible lengths for the third side, X
Answer:
100-500
Step-by-step explanation:
Both sides of a triangle cannot be shorter than the remaining side. Thus, the side must be less than 500 units. With the same rule, the side must be greater or equal to 100 units, as if it was less, then 200 + 99 < 300.
The compound inequality for the range of the possible lengths for the third side will be 100- 500.
What is inequality?Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.
The meaning of inequality is to say that two things are NOT equal. One of the things may be less than, greater than, less than or equal to, or greater than or equal to the other things.
p ≠ q means that p is not equal to qp < q means that p is less than qp > q means that p is greater than qp ≤ q means that p is less than or equal to qp ≥ q means that p is greater than or equal to qGiven:
side lengths of 200 units and 300 units.
The largest value of the third side will be
200+300=500
and, the smallest value will be
300-200=100
