Answer:
25t = 65
Step-by-step explanation:
Given that :
Profit earned = $60
Charge per hour = $25
Randy's cost or expenses = $(2 + 3) = $5 per job
Profit = (charge per hour * t) - cost
Where t = time
$60 = ($25 * t) - $5
$60 = $25t - $5
$25t = $65

A line passes through the points (-3, -1) and (-5, 4). What is the slope.of this line
Answer:
-2/5
Step-by-step explanation:
[tex]y_{2} - y_{1} \\x_{2} -x_{1} \\4- -1= 5\\ -5--3=-2 \\y=-\frac{2}{5}[/tex]
tl;dr: The slope is -5/2.
Hello!
First, if you get graphing paper and place those points, you'll see that the line is going down instead of up. This tells us that the slope is negative.
Now, we use the rise/run strategy.
Doing so, we are given 5/2. Since this is a negative, the slope will actually be -5/2.
So, the slope is -5/2.

Robert bought 3 baseball caps for the same amount and 1 baseball jersey that cost $45. Without tax, the total cost of the items is $90. What is the cost of each baseball cap?
Answer: The cost of each baseball cap = $15.
Step-by-step explanation:
Let x = cost of each baseball cap
Given; cost of each baseball jersey= $45
Total coast of 3 baseball caps and 1 baseball jersey = $90
i.e. [tex]3x+45=90[/tex]
[tex]\Rightarrow\ 3x=45\\\\\Rightarrow\ x=\dfrac{45}{3}\\\\\Rightarrow\ x= 15[/tex]
Hence, the cost of each baseball cap = $15.

Given h(x) = 4x – 1, solve for x when h(x) = -9.
Answer:
-2
Given:
h(x) = -9
Step-by-step explanation:
h(x) = 4x - 1
-9 = 4x - 1
-9 + 1 = 4x
-8 = 4x
-8/4 = x
x = -2
hope you understood❤
The solution for x when h(x) = -9 is -2
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0. A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively
Given;
h(x) = 4x – 1...(1)
h(x) = -9
Substituting the value of h(x) in equation 1
-9=4x-1
-9+1=4x
-8=4x
x=-8/4
x=-2
Therefore, the solution for the equation will be x=-2

What is the expression in factored form? please show steps on how to get both answers!
1. x2+13x +42
2. 9x^2−4
^ means its number beside is the exponent.
Answer:
1. The factored form of the given expression is (x+7)(x+6).
2. What is the expression in factored form . 9x^2 -4
Step-by-step explanation:
1. The given expression is,
The degree of the expression is 2, the constant term is 42, and the coefficient of x is 13.
Use factoring by grouping method
To find the factor form, we have to find two numbers whose sum is 13 and whose product is 42.
The factors of 42 are,
From which the sum of 6 and 7 is 13.
So We can write the 13x as 7x+6x.
2. This expression can be factorized using the difference of squares which can be illustrated as follows:
A^2 - B^2 = (A+B)(A-B)
In the given example:
sqrt(9x^2) = 3x
sqrt(4) = 2
and the two squares are separated by a negative sign
Therefore, the difference of squares is applicable
Based on this, factoring the given expression would give us:
9x^2 - 4 = (3x+2)(3x-2)

You are flying your dragon kite. It is connected to 34 yards of string. The kite is directly above the edge of a pond. The edge of the pond is 29 yards from where the kite is tied to the ground. How high is the kite above the edge of the pond? Round your answer to the nearest tenth.
Answer:
18 yards
Step-by-step explanation:
To find the height of the kite we need to consider the problem as a right triangle and use the Pythagorean theorem to solve it:
[tex] c^{2} = a^{2} + b^{2} [/tex]
Where:
c: is the length of the hypotenuse
a and b: are the length of the sides of the triangle
We have that the length of one side is 29 yards and the length of the hypotenuse is 34 yards, so we need to find the other side (which represents the height) as follows:
[tex] a = \sqrt{c^{2} - b^{2}} = \sqrt{(34)^{2} - (29)^{2}} = 18 [/tex]
Therefore, the height of the kite is 18 yards.
I hope it helps you!
