Answer:
x = 4, y = -3
Step-by-step explanation:
Find the slope intercept form first (y = mx + b):
the one going down is y = -1/2x - 1 (slope is negative, down 1 over 2, and the y-intercept is at (0, -1) )
the one going up is y = 1/4x - 4 (slope is up 1 over 4, and the y-intercept is at (0, -4)
Convert them into standard form (Ax + By = C):
1st equation: multiply the entirety of both sides by 2 to get rid of the fraction:
2y = -1x -`2
add 1x to both sides: 1x + 2y = -2
2nd equation: multiply the entirety of both sides by 4 to get rid of the fraction:
4y = 1x - 16
subtract 1x from both sides: -1x + 4y = -16
Isolate a variable:
-x + 4y = -16
-x = -4y - 16
x = 4y + 16
Plug that into other equation:
1(4y + 16) + 2y = -2
6y + 16 = -2
6y = -18
y = -3
Substitute y into the isolated equation:
x = 4(-3) + 16
x = -12 + 16
x = 4
Which of the following is a solution to the equation2/3 x + 16 = -14?
Answer:
x= -45

Answer:
This probaly sounds a little confusing
Step-by-step explanation:
1 day = 10 laps
1 lap = 400 meters
1 km = 1000 meters
12 km = ? days
We can use this information to find out a lot that we don't know.
HOW MANY METERS PER DAY??
In order to find the number of meters in a day, we think, "She ran 400 meters 10 times... 400 times 10... that's 4000 meters in one day."
1 day = 4000 meters (10 x 400 meters)
HOW MANY KILOMETERS PER DAY?
In order to find the number of km in a day, we can think, "One thousand is a kilo. There are 4 'one thousand's in 4000. Kali ran 4 kilometers (literally 4 thousand meters) per day.
1 day = 4 km (4000 m / 1000)
From here you can solve simply by thinking "How many 4km does it take to get to 12km?"
4 x ? = 12
? = 12 / 4
? = 3

Mr. McGill is solving the following problem: 42x=163. Mr. McGill set 2x=3 and got x=32 as his answer. Tell the mistake Mr. McGill made and tell the correct answer.
Answer:
The mistake McGill made was to eliminate 4 and 16 from both sides before solving fro x
Step-by-step explanation:
Given the expression
42x = 163
To get the values of x, we are to divide both sides by the coefficient of x i.e 42 as shown;
42x = 163
42x/42 = 163/42
x = 163/42
x = 3.88
Hence the mistake McGill made was to eliminate 4 and 16 from both sides before solving fro x

The high temperatures for the last seven days are: High Temperatures: 81, 78, 83, 89, 80, 87, 78
Find the MODE of the temperatures.
Answer: 78
Step-by-step explanation:
The mode is the number that appears the most number of times. In this case the number 78 appears twice unlike the other numbers that only appear once. Hence, 78 is the mode :)
Answer:
78
Step-by-step explanation:
The mode is the value that appears most often in a set of data. The mode of a discrete probability distribution is the value x at which its probability mass function takes its maximum value. In other words, it is the value that is most likely to be sampled.

The right rectangular prism below is made up of 8 cubes. Each cube has an edge length of 12 inch.
Answer:
1 in³
Step-by-step explanation:
Complete question
The right rectangular prism below is made up of 8 cubes each cube has an edge length of 1/2 inch what is the volume of this prism
Volume of a cube = l³
If each cube has an edge length of 1/2 inch, then:
Volume of each cube = 1/2³
Volume of each cube = 1/8
Volume of the prism = 8×1/8
Volume of the prism = 1 in³

If p(x)=x^2+x+1 and Q(x)=5x^2-1, find the following
1. Q(4)
2.p(-4)
3.p(1/2)
Answer: 1. 79
2. 13
3. 7/4
Step-by-step explanation:
Q(x)=5x^2-1
Q(4)=5(4)^2-1
=5(16)-1
=80-1
Q(4) = 79
p(x)=x^2+x+1
p(-4)=(-4)^2+(-4)+1
=16-4+1
p(-4) =13
p(x)=x^2+x+1
p(1/2)=(1/2)^2+(1/2)+1
=1/4+1/2+1
2+4+8/9
=14/8
p(1/2) = 7/4

Consider the ready-made tent with flooring included that is shown in de diagram below.
What is the least amount of fabric needed to make the four-foot high tent?
Answer:
136 ft²Step-by-step explanation:
Total surface area is the amount of fabric:
S = 2(1/2*6*4) + 2(7*5) + (7*6) = 136 ft²A box has a surface area of 450 cm². Its length and width are 6 and 8 respectively. What is its height?
Answer:
9.4 cm
Step-by-step explanation:
Given: Box; Length = 6 cm, Width = 8 cm, Surface area = 450 cm²
To Find: Height
Solution:
Divide the volume by the product of the length and width to calculate the height of a rectangular object.
6 × 8 = 48
450 ÷ 48 = 9.4
For this box, the rectangular object has a length of 6 cm, a width of 8 cm, and a volume of 450 cm². The product of 6 and 8 is 48, and 450 divided by 48 results in 9.4.
The height of the object is 9.4cm.
How do I solve this arithmetic sequence?
Answer:
The 16ᵗʰ term of this sequence is 82
Step-by-step explanation:
Here,
First Term = a₁ = 9
Common Difference = (d) = 2
Now, For 16ᵗʰ term, n = 16
aₙ = a + (n - 1)d
a₁₆ = 7 + (16 - 1) × 2
a₁₆ = 7 + 15 × 5
a₁₆ = 7 + 75
a₁₆ = 82
Thus, The 16ᵗʰ term of this sequence is 82

Answer:
[tex]\displaystyle [-2, -1][/tex]
Step-by-step explanation:
To use the Elimination method, you must get rid of one pair of variables, so that one side is set to zero. So, in this case, we must get rid of [tex]\displaystyle x,[/tex]therefore we will split the second equation in negative half :
[tex]\displaystyle \left \{ {{y = 2x + 3} \atop {-\frac{1}{2}[y = 4x + 7]}} \right. \\ \\ \\ \left \{ {{y = 2x + 3} \atop {-\frac{1}{2}y = -2x - 3\frac{1}{2}}} \right. \\ \\ \frac{1}{2}y = -\frac{1}{2}; -1 = y, -2 = x \\ \\ \\ \boxed{[-2, -1]}[/tex]

Answer:
20 fl ounce = 1 pt and 4 fl oz
Step-by-step explanation:
We want to convert fluid ounce to pint and fluid ounce
Mathematically;
Mathematically, 1 pint = 16 fluid ounce
Now we can write 20 fluid ounce as;
16 fl ounce + 4 fl ounce
Since 16 fl ounce is a pint, we have it that;
20 fluid ounce is 1 pt 4 fl oz
