Question 10
Jordan is trying to graph the following inequality: y < 2x – 10
He plugs in (0, 0) like this: 0 < -10
He decides that this is true, so he shades the side with (0, 0).
What did Jordan do wrong?
Answer:
Step-by-step explanation:
"0 < -10" is actually false, so Jordan has shaded the wrong side.
A least squares regression line was calculated to relate the length (cm) of newborn boys to their weight in kg. The relationship between Length and Weight has an Rsquared of 58.6%. Write a sentence (in context) summarizing what the Upper R squared says about this regression.
Answer:
58.6% of the variation in length (in cm) of new born boys and their weight (in kg) is explained by the line of best fit.
Step-by-step explanation:
Given the following :
R² value = 58.6% comparing the length (cm) of new born boys to their weight (kg)
The R² value is called the Coefficient of determination. It is obtained by taking the square of the correlation Coefficient (R). The value gives the proportion of Variation between the independent and dependent variables which is explained by regression line. In the scenario above, the R² value means that 58.6% of the variation in length in centimeter of new born boys and their weight (in kg) is explained by the line of best fit. While (100% - 58.6% = 41.4%) is due to other factors.

Ben is traveling to Santa Cruz and needs a full tank of gas. A full tank of gas gives him a total of 260 miles until empty. So Ben goes to the gas station to fill up his tank but he only has $11.86. If $11.86 only gives Ben a total of 60 miles until empty, how much money does he need in all, to get a full tank of gas to drive to Santa Cruz? Round your answer to the nearest dollar. ?
260 miles / 60 miles = 4 1/3
He would need 4 1/3 more gas:
11.86 x 4 1/3 = 51.39
he would need $51.39

BRAINALEST!!!!!!!!!! 1/2 + 2/9 + 1/6
Answer:
8/9
Step-by-step explanation:
Solving
Step 1: Find the LCM of the denominators 2, 9, and 6:
Multiples of 2: 2, 4, 6, 8, 10, 12, 14, 16, 18, 20Multiples of 9: 9, 18, 27, 36, 45, 54, 63, 72, 81, 90Multiples of 6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60As you can see, the LCM of these denominators is 18Step 2: Convert each fraction into an equivalent decimal with denominator as 18.
[tex]\frac{1}{2} = \frac{x}{18}[/tex], [tex]\frac{1*9}{2*9}= \frac{9}{18}[/tex] [tex]\frac{2}{9} = \frac{x}{18} , \frac{2*2}{9*2} = \frac{4}{18}[/tex] [tex]\frac{1}{6} =\frac{x}{18} , \frac{1*3}{6*3} =\frac{3}{18}[/tex]Step 3: Add the fractions.
9/18 + 4/18 + 3/1813/18 + 3/1816/18 (GCF of 16 and 18 is 2)16/2 = 8, 18/2 = 98/9Have a lovely rest of your day/night, and good luck with your assignments! ♡
Answer:
8/9
Step-by-step explanation:
Take LCM of denominators 2, 9 & 6 = 18
1/2
[ 18/2 = 9 ]
Multiply 9 to both numerator and denominator,
1/2 * 9/9
= ( 1*9 )/( 2*9 )
= 9/18
2/9
[ 18/9 = 2 ]
Multiply 2 to both numerator and denominator,
2/9 * 2/2
= ( 2*2 )/( 9*2 )
= 4/18
1/6
[ 18/6 = 3 ]
Multiply 3 to both numerator and denominator,
1/6 * 3/3
= ( 1*3 )/( 6*3 )
= 3/18
( The denominator need to be same in order to add the fractions )
1/2 + 2/9 + 1/6
= 9/18 + 4/18 + 3/18
= ( 9 + 4 + 3 )/18
= 16/18
16 = 2*8
18 = 2*9
16/18
= ( 2*8 )/( 2*9 )
= 8/9
Turn y=1/2x + 3/2 into standard form
=============================================
Work Shown:
y = (1/2)x + 3/2
2y = x + 3 .... multiply every term by the LCD 2
2y-x = 3 ... subtract x from both sides
-x+2y = 3
x-2y = -3 ... multiply both sides by -1
The last step is done so that the x coefficient is positive
The equation is in the form Ax+By = C with
A = 1B = -2C = -3You could have your answer as -x+2y = 3, since that is also in standard form. But many math textbooks make A > 0.

how do I solve for x here??
I just need help with finding x
Answer:
x = 15
Step-by-step explanation:
The solution to any problem is found by making use of the relations you know between the parts of the problem. Here, values of x relate to the arc measures around a circle. The relation you know is the sum of the arcs around a circle is 360°. Using this relation, you can write the equation ...
7x° +4x° +6x° +7x° = 360°
The equation can be solved for x by making use of the rules of algebra.
24x = 360 . . . . . . . . . . . . . . divide by °, collect terms
x = 15 . . . . . . . . . . . . . . . . divide by 24

What is the value of s?
Answer:
s = 26°
Step-by-step explanation:
The total degrees of a triangle is 180°
1. Create the formula: [tex]180=50+2s+3s[/tex]
2. Solve for S
[tex]180=50+2s+3s\\180=50+5s \\ 180-50=5s \\ 130=5s\\\frac{130}{5} =s \\ 26=s[/tex]
3. Check by plugging in 26
[tex]180=50+2(26)+3(26)\\ 180=50+52+78\\ 180=180[/tex]

Which type of demand has been created?
When the mortgage rates get high, the housing market will collapse, as fewer people will take loans for buying houses because of higher interest rates, and this will result in a demand.
Answer:
Scarce demand / inflation
The word "scarce" means low on supplies or anything else.
Inflation is the term used when a price increases in the market.
These two terms together would best describe the higher demand.
Hope this helps, have a great day! ♥

Step-by-step explanation:
5% commission rate of 14.98 is what?
Answer:
$0.75
Step-by-step explanation:
To find the answer we simply multiply the amount of money earned by the percentage.
So the total amount of money = $14.98
And the percentage = 5%
But I order to calculate this we must first turn the percentage into a decimal. To do this we decide the number of the percentage by 100
In this case that is 5/100=0.05
We can now multiply this by the amount of money to get 0.05*14.98=0.749
We then round our answer to two decimal places (because money can not go past two) to get $0.75
SV is a midsegment of △RTU.
If TU=y+38 and SV=y–9, what is the value of y?
Answer:
y = 56
Step-by-step explanation:
the midsegment SV is half the length of the side TU , that is
y - 9 = [tex]\frac{1}{2}[/tex] (y + 38) ← multiply both sides by 2 to clear the fraction
2y - 18 = y + 38 ( subtract y from both sides )
y - 18 = 38 ( add 18 to both sides )
y = 56
