Answer:
[tex] 7.25p \le 35 [/tex]
Step-by-step explanation:
p = number of picture frames
Each picture frame costs $7.25, so p picture frames cost p * 7.25, or 7.25p.
She has $35, so the total cost must be less than or equal to $35.

Choose the inverse of y=x^2-10
Answer:
x = 5 + sqrt(y+25), for x>=5
x = 5 - sqrt(y+25), for x<=5
Step-by-step explanation:
y = x^2 - 10x + 25 - 25
y = (x-5)^2 - 25
y+25 = (x-5)^2
x-5 = +/-sqrt(y+25)
And you get TWO inverses:
x = 5 + sqrt(y+25), for x>=5
x = 5 - sqrt(y+25), for x<=5

Write your answer as a fraction or whole number. P(powdered sugar donut) =
Answer:
[tex]P(\text{Powdered sugar donut})=\dfrac{1}{15}[/tex] .
Step-by-step explanation:
It is given that Wendy's mother recorded how many donuts she has eaten over the past few months.
Jelly-filled donuts = 6
Maple donuts = 53
Glazed donuts = 11
Powdered sugar donuts = 5
Now,
Total number of donuts = 6 + 53 + 11 + 5 = 75
We need to find the experimental probability that the next donut Wendy eats will be a powdered sugar donut.
[tex]P(\text{Powdered sugar donut})=\dfrac{\text{Powdered sugar donuts}}{\text{Total number of donuts}}[/tex]
[tex]P(\text{Powdered sugar donut})=\dfrac{5}{75}[/tex]
[tex]P(\text{Powdered sugar donut})=\dfrac{1}{15}[/tex]
Therefore, [tex]P(\text{Powdered sugar donut})=\dfrac{1}{15}[/tex].
The graph of f(x) = 2x + 1 is shown below. Explain how to find the average rate of change between x = 2 and x = 5. (10 points) Graph of 2 to the power of x plus 1

The graph for the equation y = negative 2 x + 1 is shown below. On a coordinate plane, a line with negative slope goes through (0, 1) and (1, negative 1). If another equation is graphed so that the system has no solution, which equation could that be?
Options:
y = negative 2 (x minus one-half)
y = negative one-half (4 x + 2)
y = negative x + 1
y = negative one-half x + 2
Answer:
y = negative 2 (x minus one-half)
Step-by-step explanation:
The equation of a line is given as:
y = mx + c, where m is the slope and c is the intercept on the y axis.
The equation of a line going through (0, 1) and (1, - 1) is calculated using:
[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\ y-1=\frac{-1-1}{1-0}(x-0)\\ y-1=-2x\\y=-2x+1[/tex]
The solution of two lines is at their point of intersection. The equation of the line that would not have any solution with y = -2x + 1 would be a line that is parallel to y = -2x + 1. Since the two lines would be parallel to each other, their would be no intersection and therefore no solution.
Two lines are said to be parallel to each other if they have the same slope. The slope of y = -2x + 1 is gotten by comparing with y = mx + c, therefore the slope m = -2. From the options the only line with a slope m = -2 is y = -2(x -1/2). Therefore y = -2(x -1/2) is parallel to y = -2x + 1 and would have no solution

Rita purchased two loaves of wheat bread. Each loaf was $1.89. How much
money did Rita spend in all? Do not include $ in your answer.
Answer: 3.78
Step-by-step explanation:
Because she bought 2 $1.89 loaves, she spent 2 * 1.89, or 3.78 dollars.
Hope it helps <3
Answer:
3.87Step-by-step explanation:
This is because you have to multiply the number of 1.89 by 2. This is equal to 3.87.
Given:
Price of one bread = 1.89
Unknown:
Total money used = ?
So,
1.89 * 2 = 3.87
or
1.89 + 1.89 = 3.87
Total money used is 3.87.Hope this helped,

What is the common difference between successive terms in the sequence? 9, 2.5, –4, –10.5, –17, ... –11.5 –6.5 6.5 11.5
Answer:
d = -6.5
Step-by-step explanation:
Simply take 2 side-by-side numbers and subtract them to find your common difference:
d = -4 - 2.5 = -6.5
Answer:
B. -6.5
explanation:
Basiclly what the person above said, to find the common number, subtract two numbers together. After it gives you the common ration, prove the answer it gives you by adding the common ration with a number in the sequence to give you the number before, example:
9 - 2.5 = 6.5
6.5 + 2.5 = 9

Answer:
so the coordinates of C are (12,29)
Step-by-step explanation:
as we know that CD is a line segment and M is its mid-point in order to find the coordinates of C we will use mid-point formula
[tex]M(x,y)=(\frac{x1+x2}{2},\frac{y1+y2}{2})[/tex]
putting the values of known coordinates
[tex](15,-6.5)=(\frac{x1+18}{2},\frac{y1+(-16)}{2})[/tex]
comparing the coordinates separately
[tex]15=\frac{x1+18}{2}[/tex] and [tex]-6.5=\frac{y1-16}{2}[/tex]
15×2=x1+18 and -6.5×2=y1-16
30=x1+18 and 13=y1-16
30-18=x1 and 13+16=y1
12=x1 and 29=y1
so the coordinates of C are (12,29)
in order to check the values put it back in the mid-point formula to find the coordinates of M

An x-method chart shows the product a c at the top of x and b at the bottom of x. Below the chart is the expression a x squared + b x + c Consider the trinomial x2 + 10x + 16. Which pair of numbers has a product of ac and a sum of b? What is the factored form of the trinomial?
Answer:
The pair of numbers that has a product of ac and a sum of b = (+2, +8)
The factored form of the trinomial = (x+2) (x+8)
Step-by-step explanation:
ax² + bx + c = 0
This is in the form of a trinomial algebraic expression
Given trinomial: = ax² + 10x + 16
Where a = 1, b= 10, c= 16
To find the pair of numbers that has a product of ac and a sum of b, we would solve the equation.
Using factorisation method:
ac = a×c = 1×16 = 16
Let's find the factors of 16 whose sum gives +10 and product gives +16
Factors of 16 = 1, 2, 8, 16
+2 + +8 = +10
+2 × +8 = +16
The factors are +2 and +8
The pair of numbers that has a product of ac and a sum of b = (+2, +8)
x² + 10x + 16 = x + 2x + 8x + 16
x² + 10x + 16 = x(x+2) + 8(x+2)
= (x+2) (x+8)
The factored form of the trinomial = (x+2) (x+8)
Answer:
(x+2) (x+8)

Answer:
2x^2 -x +1 = 0
Step-by-step explanation:
For roots α and β, the original equation can be factored as ...
f(x) = 2(x -α)(x -β)
If we add 1 to each of those roots, the factors become ...
g(x) = 2(x -(α+1))(x -(β+1))
This can be rearranged to be ...
g(x) = 2((x -1) -α)((x -1) -β)
That is, we can get the desired equation by replacing x with x-1, effectively shifting the function right one unit.
2(x -1)² +3(x -1) +2 = 0
2x^2 -x +1 = 0

F
Answer:
yes, if AB ≅ DE
Step-by-step explanation:
Triangles are said to be congruent if they have the same sides and the same angles.
The following measures are used to determine if triangles are congruent:
1) Angle-side-angle: If two angles and a side of a triangle is equal to two angles and corresponding side of another triangle, then they are congruent.
2) Side-side-side: If all three sides of a triangle is equal to three sides of another triangle, then the two triangles are congruent.
3) Side angle side: If two sides and an included angle of a triangle is equal to the two sides and corresponding angle of another triangle, then they are congruent.
4) Hypotenuse - leg: If the hypotenuse and one leg of a triangle is equal to the hypotenuse and leg of another triangle then they are congruent.
From the triangles DEF and ABC, already, they already have one equal triangle that is ∠F = ∠B and an equal side i.e DF = AC.
To satisfy congruence, two sides and an angle have to be equal, therefore if AB = DE then the two triangles would be congruent
Answer:
D). no, because the hypotenuses must have different lengths
