if John has test scores of 90 and 76 with one test remaining to be taken, what score must he make on the last test to end up with an 86 average?
Answer: The last score must be 92%
Step-by-step explanation: To find the average, you add all the terms, then divide by the number of terms.
86 = [tex]\frac{90 + 76 + x}{3}[/tex]258 = 90 + 76 + x (multiple both sides by 3)258 = 166 + x (combine like terms)92 = x (subtract 166 from both sides)i bet nobody will anser this =P. Solve 52.425 divided by 0.5

Answer:
v = 3.2
Step-by-step explanation:
12v - 38 = (4v-3)/8
multiply each side by 8 to get:
96v - 304 = 4v - 3
92v - 304 = -3
92v = 301
v = 3.27

Why would the end point for the function be (0,0)
Answer:
Yes, you are correct. It is (0,0)
Step-by-step explanation:
The lower left side of the curve hits the axis at 0,0 so you are correct. Try it
S = 365√x
Let x = 0
The square root of x when x = 0 is 0.
So S = 365√0
S = 0

Write the equation in slope-intercept form. y+5=−6(x+7)
i need answers to these in 10 minutes.
Answer:
a) The inverse is g(x) = (1/70)*x - 50/70
b) The slope intercept form is y = -6*x - 47
Step-by-step explanation:
a) When we have a function f(x), the inverse of this function (let's call it g(x)) is such that:
g(f(x)) = x
f(g(x)) = x
for every x.
In this case, we have:
f(x) = 70*x + 50
This is a linear function, and the inverse will be also a linear function.
Then the inverse will be something like:
g(x) = a*x + b
then:
g( f(x)) = x = a*( 70*x + 50) + b
then we can just solve the equation:
x = a*( 70*x + 50) + b
x = a*70*x + a*50 + b
If we separate terms by the powers of x in each side of the equation, we have:
1*x + 0*x^0 = (a*70)*x + (a*50 + b)*x^0
(where x^0 = 1)
then:
1 = (a*70)
a = 1/70
and:
0 = (a*50 + b)
0 = 50/70 + b
-50/70 = b
Then the inverse of f(x) is:
g(x) = (1/70)*x - 50/70.
b) The slop-intercept form of a linear equation is:
y = a*x + b
where a is the slope, and b is the y-intercept.
We want to write in this form the equation:
y + 5 = -6*(x + 7)
The first step is to isolate the "y" in one side of the equation:
y = -6*(x + 7) - 5
Now let's simplify the right side:
y = -6*x - 6*7 - 5
y = -6*x - 42 - 5
y = -6*x - 47
This is the slope-intercept form, where the slope is -6, and the y-intercept is -42.
Solve for p.

Thelma and Louise ordered take-out from Belle Taco. Thelma ordered 2 tacos and 1 quesadilla and paid $5.51. Louise ordered 2 quesadillas and 1 taco and paid $7.09.
Answer:
The cost of 1 taco is $1.31 and 1 quesadilla is $2.89
Step-by-step explanation:
Let [tex]x[/tex] be the cost of 1 tacos and [tex]y[/tex] be the cost of 1 quesadilla
Thelma's order
[tex]2x+1y=5.51\quad\ldots(i)[/tex]
Louise's order
[tex]1x+2y=7.09\quad\ldots(ii)[/tex]
Performing the operation [tex]2\times (i)-(ii)[/tex] we get
[tex]4x+2y=11.2[/tex]
[tex]x+2y=7.09[/tex]
[tex]3x=3.93\\\Rightarrow x=\dfrac{3.93}{3}\\\Rightarrow x=1.31[/tex]
[tex]2x+y=5.51\\\Rightarrow 2\times 1.31+y=5.51\\\Rightarrow y=5.51-(2\times 1.31)\\\Rightarrow y=2.89[/tex]
The required answer is
The cost of 1 taco is $1.31 and 1 quesadilla is $2.89.

How is the graph of
f(x) = -3x2 – 4 different from the graph of f(x) = -3x2
Answer:
Both have the same line of symmetry but different turning points
But I maintain that if you had taken a shot of the entire question I would be of much help
Step-by-step explanation:
f(x)=-3x²-4
dy/dx=-6x
-6x=0
x=0
The line of symmetry of this parabola occurs at x=0
The minimum value of the curve is
f(0)=-3(0)²-4=-4
For f(x)=-3x²
dy/dx=-6x²
-6x²=0
x=0
The line of symmetry occurs at x=0
The maximum value=-3(0)²=0
Write the equation of the function on the graph.
Answer:
[tex] \huge \boxed {y = |x| + 3}[/tex]
Step-by-step explanation:
Similar to Parabola, except this is Modulus Function.
[tex] \boxed {y = a |x - h| + k} \\ a \: = slope \\ h = move \: \: to \: \: x - axis \\ k = move \: \: to \: \: y - axis[/tex]
From the graph. The graph doesn't have any movement/transformation to x-axis, only y-axis. The graph only shifts up 3 units from y = |x|.
Both slopes are also 1 (from rise/run)
Hence, the answer is
[tex]y = |x| + 3[/tex]

. What is the value of x in the equation .5(x-2) = 3(x-4) - 14?
Answer: -8
Step-by-step explanation:
Solve for x
5 (x − 2) = 3 (x − 4) − 14
5x − 10 = 3 (x − 4) − 14
5x − 10 = 3x − 12 − 14
5x − 10 − 3x = −26
2x = −26 + 10
2x = −16
x = −8

answer of this equation is (-8)

Last week Rachel power watch 2 3/5 miles per day on each of the seven days during the same week she also jobbed 5 3/4 miles per day on 4 days what was the total amount of Miles Rachel power walk and Jog last week
Answer:
41.2 miles
Step-by-step explanation:
The computation of the total amount of miles rachel walk and jog last week is as follows;
Unit rate per day is
= 2 3 ÷ 5
= 13 ÷ 5
= 2.6 miles
In 7 days, she walked
= 2.6 miles × 7 days
= 18.2 miles
Now for four days, the unit per day is
= 5 3 ÷ 4 × 4
= 23 ÷ 4 × 4
= 23 miles
So, the total amount of miles would be
= 18.2 miles + 23 miles
= 41.2 miles

Answer:
Step-by-step explanation:
the ratio between similar triangles are constant.
so 11/14 has to be equal to z/8 and also a15 = 11/14
so from this we can conclude that z = 8*14/11 = 10.18
Answer:
z = 11 and a = 12
Step-by-step explanation:
These two triangles are similar, in this case, the same angles but different sizes. The answer to this problem is the length of the sides of the triangles. You are given the right side's length on both triangles. The first triangle's sides are 3 (inches, cm, whatever form of measurement is being used) bigger than the second triangle's. Using this information, you can figure out the quantity of both a and z.

The function f(x)f(x) is graphed below. Determine whether the degree of the function is even or odd and whether the function itself is even or odd.
Answer:
The degree is even and the function is even.
Step-by-step explanation:
The graph is a parabola, indicating that the degree is even.
The defintion of an even function is that f(x)=f(-x), and by observing the graph of the function, we will be able to verify that f(x)=f(-x). It is therefore an even function.
The degree of the function is even and the function will be even.
What is a function?A statement, principle, or policy that creates the link between two variables is known as a function. Functions are found all across mathematics and are required for the creation of complex relationships.
The function f(x) is graphed below.
The graph of the function is parabolic whose vertex is at (0, -30). And the curve is passing through the x-axis.
Then the equation of the curve will be
f(x) = ax² - 30
Where a is the leading coefficient.
Then the degree of the function is even and the function will be even.
