At 100 Fahrenheit a certian insect Chirps at a rate of 94 times per minute and at 103 Fahrenheit they trip at 112 times per minute write an equation in slope intercept form that represents the situation
Answer:
y=6x-506
Step-by-step explanation:
Start by finding the slope.
Let your x-axis be temperature and you y-axis be chirps per minute.
This leaves you with your two points to find slope.
The first point would be (100,94) and your second point would be (103,112).
From here we can do the standard slope equation [tex]\frac{y_{2}-y_{1} }{x_{2} -x_{1} }[/tex].
[tex]\frac{112-94}{103-100}[/tex]=[tex]\frac{18}{3}[/tex]
[tex]\frac{18}{3}[/tex] Is your slope for the line which can be simplified to 6.
Next find your y-intercept. This can be found by moving around your
y=mx+b equation.
y-mx=b
Pick a point to substitute into the equation. Ill use (103, 112).
[tex]112-6(103)=b[/tex]
[tex]112-618=b[/tex]
[tex]-506=b[/tex]
[tex]b=-506[/tex]
Knowing slope and the y-intercept we can write the slope intercept equation
y=6x-506

in September how much money did he cam
er earns $102 esch day for mowing several laws. If he moves the firm for 25 days
Answer: $2,550
Step-by-step explanation:
I’m not 100% sure what this question is asking.
But if it’s asking “how much money does he earn in total if he mows for 25 days and if he earns $102 each day”, then that would be your answer.
Since there is 25 days, and he earns $102 each day, you would multiply 25 by 102.
Then your answer (his total amount of money earned once he has mowed for 25 days) would be: $2,550.

How many numbers x between 1 and 100 (inclusive) have the property that x2+x3 is a perfect square?
(Please help. I'm suffering)
=========================================================
Explanation:
Factor the given expression
x^2+x^3
x^2*1+x^2*x
x^2(1+x)
x^2(x+1)
We end up with something where the factor x^2 is a perfect square regardless of whatever we replace x with from the set {1,2,3,...,99,100}.
In short, we don't need to worry about the x^2 portion.
--------------------
The only thing of importance is the x+1 factor.
The x+1 must be a perfect square so that the original expression is as well.
Let's say M is some perfect square between 1 and 100. That means M belongs to the set of values
{1, 4, 9, 16, 25, 36, 49, 64, 81, 100}
If we want M+1 to be a perfect square, then we'll need to subtract 1 from each item in that set above to counteract the "plus 1" in "M+1".
Subtract 1 from each item to end up with this modified set
{0, 3, 8, 15, 24, 35, 48, 63, 80, 99}
--------------------
Every item mentioned in that second set will make x^2+x^3 to be a perfect square.
For example, let's pick x = 15
x^2(x+1) = 15^2*(15+1)
x^2(x+1) = 15^2*16
x^2(x+1) = 15^2*4^2
x^2(x+1) = (15*4)^2
x^2(x+1) = 60^2
This confirms that x^2+x^3 is a perfect square for x = 15. I'll let you check the other values.
There are 10 values in the set {1^2,2^2,...,9^2,10^2} = {1,2,...,81,100}. There are also 10 values in the set {0,3,8, ..., 80, 99} we got earlier. The cardinality hasn't changed. However, we'll kick out 0 because it's not between 1 and 100. So we end up with 9 as our final answer.
--------------------
To summarize, there are 9 values of x that make x^2+x^3 a perfect square, where x is some whole number between 1 and 100 inclusive.
Simplify the expression by combining like terms. Then,
evaluate the expression by substituting the given values
for the variables.
x=5 and y=2
y^2 + xy – 7y^2
Answer:
-14
Step-by-step explanation:
The like terms in this equation is y^2 and -7y^2 so combining the two the equation becomes:
xy-6y^2
Then we substitute the values in:
5×2-6×2^2 = -14

Plot C (-4,-5). D(-4,3), E (-3,2), and F(-8,2) in a coordinate plane. Are CD and EF congruent?
Answer: No
Step-by-step explanation:
1. The distance between C (-4,-5) and D (-4,3) is 8
2. The distance between E (-3,2) and F (-8, 2) is 5
3. Since the measurements are not the same, the segments cannot be
congruent
if the gradient of a line is 2 and (7,2) is a point on the line, find it's equation
Answer:
y = 2x - 12
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Here m = 2 , then
y = 2x + c is the partial equation
To find c substitute (7, 2 ) into the partial equation
2 = 14 + c ⇒ c = 2 - 14 = - 12
y = 2x - 12 ← equation of line

Please answer the math problem... I will mark you brainliest
Answer:
t = 128°
Step-by-step explanation:
A triangle equals 180°. 2/3 of the angles in the triangle are given, so we would then do the following:
180 - (61 + 67) = x
180 - 128 = x
52 = x
Since a straight line also is 180°, this would mean x + t = 180.
x = 52
We would then convert the equation to the following:
180 - 52 = t
128 = t
The angle "t" is a 128° angle.
bChoose the equation that represents the graph.
Oy = x - 3
Oy = -x + 3
Oy = -x-3
Oy = x + 3
The graph illustrates a linear function, because the graph is a straight line
The equation of the graph is (d) y = x +3
The points on the line are:
[tex](x_1,y_1) = (-3,0)[/tex]
[tex](x_2,y_2) = (0,3)[/tex]
First, we calculate the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Substitute values for x1, x2, y1 and y2
[tex]m = \frac{3-0}{0--3}[/tex]
Simplify
[tex]m = \frac{3}{3}[/tex]
Divide
[tex]m = 1[/tex]
The equation of the line is then calculated using the following formula:
[tex]y = m(x - x_1) + y_1[/tex]
Substitute values for m, x1 and y1
[tex]y = 1(x - -3) + 0[/tex]
Simplify
[tex]y = 1(x +3)[/tex]
Open bracket
[tex]y = x +3[/tex]
Hence, the equation of the graph is (d) y = x +3
