solve this system of equations using the substitution method
y=x+7
-2x-11=y
Answer:
x=-6, y=1
Step-by-step explanation:
Let's solve your system by substitution.
y=x+7;−2x−11=y
Step: Solve y=x+7 for y:
y=x+7
Step: Substitute x+7 for y in −2x−11=y:
−2x−11=y
−2x−11=x+7
−2x−11+−x=x+7+−x(Add -x to both sides)
−3x−11=7
−3x−11+11=7+11(Add 11 to both sides)
−3x=18
−3x/ −3 = 18/ −3 (Divide both sides by -3)
x=−6
Step: Substitute−6 for x in y=x+7:
y=x+7
y=−6+7
y=1 (Simplify both sides of the equation)
Answer:
x=−6 and y=1
My favorite bagel shop has 12 types of bagels, 10 types of cream cheese, and can choose to have it toasted or not . How many different bagels can order?
Answer: 240
Step-by-step explanation:
Given
Shop has 12 types of bagels, 10 types of cream and a option for roast
For making a bagel there are 12 choices to select a bagel, following this there are 10 choices for cream with a option to roast
So, total no different bagels that can be made out of the given is
[tex]\Rightarrow 12\times 10\times 2\\\Rightarrow 240\ \text{types}[/tex]
Two expressions are shown below:
1. 514÷23
2. 514×32
Without solving these expressions, determine if they are equivalent. How do you know? (Please help..)
Answer:
Clearly they are not equivalent because division will get you a smaller number ( except when decimals are in used or special cases ) as an answer and division times the number that will oppositely get you a bigger number ( again, except the decimal or special cases )
The green parallelogram is a dilation of the black parallelogram. What is the scale factor of the dilation?
A) 1/3
B) 1/2
C) 2
D) 3
=============================================================
Explanation:
"The green parallelogram is a dilation of the black parallelogram"
This tells us that the preimage is the black parallelogram and the image is the green one.
In short, the mapping is [tex]\text{black} \to \text{green}[/tex]
The image is smaller than the preimage (green is smaller than black), indicating the scale factor is some value of k such that 0 < k < 1. We can rule out choices C and D because of this.
--------------------
Measuring along the top, we can see that the black parallelogram goes from x = -6 to x = 8. Check out the image shown below where I've marked your given diagram, adding on helpful lines to show this going on.
The number-line distance from x = -6 to x = 8 is 14 units, so the top side of the black parallelogram is 14 units long.
The corresponding top side of the green parallelogram is 7 units long (because it spans from x = -3 and x = 4; as shown in blue in the figure below).
Divide the image length over its corresponding preimage length to get the scale factor.
scale factor = (image length)/(preimage length)
scale factor = 7/14
scale factor = 1/2
which points to choice B as our final answer.

THE ANSWER IS C)2

Carl and Tamera want to compare their tests in math class. They have taken six tests. Should they use the mean, median or mode to compare their scores?
Answer:
Mean
Step-by-step explanation:
I said mean because it would allow both Carl and Tamera to average their scores and compare one side by side rather than comparing 6 each which would just be time consuming and it seems like it wouldn't be any other choices.
Find the Volume (look at the picture)
Answer:
V ≈ 263.9 units³
Step-by-step explanation:
The volume (V) of a cone is calculated as
V = [tex]\frac{1}{3}[/tex] πr²h ( r is the radius and h the height )
Here r = 6 and h = 7 , then
V = [tex]\frac{1}{3}[/tex] π × 6² × 7
= [tex]\frac{1}{3}[/tex]π × 36 × 7
= [tex]\frac{1}{3}[/tex]π × 252
= 84 π
≈ 263.9 units³ ( to 1 dec. place )

Melissa and Jaime are playing a game in geometry class. Melissa draws the shape below on plain white paper and has to give Jaime directions to draw a congruent shape.
I. The location of each vertex on a coordinate plane
II. The shape is a triangle. Its two longest sides measure 6 inches and 3√3 inches.
III. m∠MEL = 90°, m∠ELM = 30°, and LM = 6 inches
Which of the following descriptions of Melissa's triangle is adequate for Jaime to draw a congruent shape?
Answer:
III. m∠MEL = 90°, m∠ELM = 30°, and LM = 6 inches
Step-by-step explanation:
It´s lll Because to make a congruent shape one angle should be 90 and the longest side should be 6 inches. one angle should equal angle ELM.
So, by AAS criteria it would be congruent.
---------------------------

9. Mr. McDonald has $500.00 to spend at a bicycle store. All prices listed
below include tax. He buys a new bicycle for $273.98. He buys 3 bicycle
reflectors for $7.23 each and 1 bicycle helmet for 42.36. he plans to use
the remaining money to buy new cycling outfits for $78.12 each. Write and
solve an inequality to determine the greatest number of cycling outfits
that Mr. Mc Donald can buy with the remaining money? *
Answer:
This will explain it
Step-by-step explanation:
To answer the question, you need to determine the amount Mr. Traeger has left to spend, then find the maximum number of outfits that will cost less than that remaining amount.
Spent so far:
... 273.98 + 3×7.23 +42.36 = 338.03
Remaining available funds:
... 500.00 -338.03 = 161.97
The cycling outfits are about $80 (slightly less), and this amount is about $160 (slightly more), which is 2 × $80.
Mr. Traeger can buy two (2) cycling outfits with the remaining money.
_____
The remaining money is 161.97/78.12 = 2.0733 times the cost of a cycling outfit. We're sure he has no interest in purchasing a fraction of an outfit, so he can afford to buy 2 outfits.

The answers to your questions are given below
Step-by-step explanation:
A. 3 × 9 = 27
B. 2 × 3 × 9 = 54
Next, we shall determine which option will give the same result obtained above.
9 × 3 = 27
9 × 3 × 2 = 54
3 × (4 + 5) = 3 × 9 = 27
(2 × 3) × 9 = 6 × 9 = 54
Therefore,
3 × 9 = 27
9 × 3 = 27
3 × (4 + 5) = 27
2 × 3 × 9 = 54
9 × 3 × 2 = 54
(2 × 3) × 9 = 54
SUMMARY
3 × 9 >>>>>>>>> 2 × 3 × 9
9 × 3 >>>>>>>>> 9 × 3 × 2
3 × (4 + 5) >>>>> (2 × 3) × 9

If g(x) = 2x + 1 and f (x) = x2 + 4, find g[f(4)].
g[f(4)] =
Answer:
g(f(4)) = 41
Step-by-step explanation:
Evaluate f(4) then substitute the value obtained into g(x)
f(4) = 4² + 4 = 16 + 4 = 20, then
g(20) = 2(20) + 1 = 40 + 1 = 41
That is g(f(4)) = 41

Marcus is choosing 4 books to read from a list of 15 books. If order matters, how many ways can he choose to read the books?
4
32,760
23,760
60
Answer:
32,760
Step-by-step explanation:
Given :
Since the order matters, we use the permutation relation :
Recall :
nPr = n! ÷ (n - r)!
n = 15 ; r = 4
15P4 = 15! ÷ (15 - 4)!
15P4 = 15! ÷ 11!
15P4 = (15 * 14 * 13 * 12)
15P4 = 32,760

Q8. Look at the image.
Answer:
Option B
Step-by-step explanation:
Quadratic equation given in the question is,
[tex]x^2+4x+2=0[/tex]
By comparing this equation with the standard quadratic equation,
[tex]ax^2+bx+x=0[/tex]
[tex]a=1,b=4[/tex] and [tex]c=2[/tex]
By using quadratic formula to get the roots of the given quadratic equation,
[tex]x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]
By substituting the values of a, b and c in the formula,
[tex]x=\frac{-4\pm\sqrt{4^2-4(1)(2)}}{2(1)}[/tex]
[tex]x=\frac{-4\pm\sqrt{16-8}}{2}[/tex]
[tex]x=\frac{-4\pm\sqrt{8}}{2}[/tex]
[tex]x=\frac{-4-\sqrt{8}}{2},\frac{-4+\sqrt{8}}{2}[/tex]
[tex]x=-3.414,-0.5857[/tex]
[tex]x=-3.41,-0.59[/tex]
Therefore, Option B will be the answer.
