what is 2x - y = -42
Answers
Answer:
A linear equation
Step-by-step explanation:
It just is
Answer:
Step-by-step explanation:
2x + -1y = -42
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add 'y' to each side of the equation.
2x + -1y + y = -42 + y
Combine like terms: -1y + y = 0
2x + 0 = -42 + y
2x = -42 + y
Divide each side by '2'.
x = -21 + 0.5y
Simplifying
x = -21 + 0.5y

Which equation in slope-intercept form represents a line that passes through the point (2,3) and is
perpendicular to the line y - 9 = (0 + 7)?
Answers
Answer:
The answer is below
Step-by-step explanation:
Which equation in slope-intercept form represents a line that passes through the point (2,3) and is perpendicular to the line y−9=23(x+7)
Solution:
The equation of a line in slope intercept form is given as y = mx + b, where m is the slope and b is the y intercept.
Given a line y−9=23(x+7)
y - 9 = 23x + 161
y = 23x + 170. The slope of this line comparing with y = mx + b gives m = 23
Two lines are perpendicular if the product of their slope gives -1.
Let [tex]m_1[/tex] be the slope of the perpendicular line, hence:
[tex]m_1(23)=-1\\\\m_1=\frac{-1}{23}[/tex]
Since the perpendicular line passes through (2, 3), we can get its equation using:
[tex]y-y_1=m_1(x_x_1)\\\\y-3=\frac{-1}{23}(x-2)\\\\y= \frac{-1}{23}x+\frac{2}{23}+3\\\\ y= \frac{-1}{23}x+\frac{71}{23}[/tex]

Which graph represents the inequality x < -6?
Answers
Answer:
A.
Step-by-step explanation:
x < -6 means that x is lesser than -6. Thus, C and D are wrong. A filled up dot means that -6 is also a possible number for x, but here it says that x is lesser than -6, so it cannot be -6 itself. Thus, B with the filled up dot is also wrong.

The data manager for a state political party gathered data to determine how many citizens would support the party's senate candidate. He polled citizens in 30 similarly sized senate districts and found a sample mean of 70,438 citizens. Statewide data shows that the population standard deviation is 645.3. What is the approximate 90% confidence interval for this situation?
Answers
Answer:
The approximate 90% confidence interval is;
70,244 to 70,732
Step-by-step explanation:
Here, we want to calculate the approximate 90% C.I for the situation
Mathematically;
CI = mean ± (z * SD)/√n
From the question;
mean = 70,438
SD = 645.3
n = 30
we can get z from the CI table
90% CI is same as; 1.645 z-score
So , substituting these values;
CI = 70,438 ± ( 1.645 * 645.3)/√30
CI = 70,438 ± 194
So the CI = 70,438 -194 to 70,438 + 194
= 70,244 to 70,732
Answer:
B. 70,244 and 70,632

The ratio of dogs to cats at the SPCA is 3:2. If there are 48 cats, how many dogs are there?
Answers
Answer:
72 dogs
Step-by-step explanation:
3 dogs/2 cats = x dogs/48 cats
Cross Multiply
3/2 x x/48
2x=144
x=72
Answer:
72 dogs
Step-by-step explanation:
First turn 3:2 into a fraction:
3/2
Then you can make the equation a proportion question, which is much eaiser to handle.
3/2=x/48 (I recommend writing this out so it will be easier to see)
Then you cross multiply, or multiply by the numerator of the first fraction by the denominator of the second, and the denominator of the first fraction by the numerator of the second.
Multiply 2 by x, which becomes 2x.
Multiply 3 by 48, which is 144
This becomes... 2x=144
You then solve with equation by dividing 144/2 and getting 72.
Meaning x=72 dogs

Answers
Answer:
Square root of 85
Step-by-step explanation:
We can envision the segment AB as the hypotenuse of a right triangle with a height of 6 units and a length of 7 units. We can use the Pythagorean Theorem to solve for the length of segment AB which is similar to distance formula.
6^2 + 7^2 = c^2
36 + 49 = c^2
c^2 = 85
c = Square root of 85.
Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. The Smiths are sending out a batch of holiday cards. Emily signed of the cards. Then Josh signed of the remaining cards. Tatiana signed 20% of what Josh had left. If there were 75 cards in all, how many cards are left to be signed? There are cards yet to be signed.
Answers
Answer:
You will get 75 cards
Step-by-step explanation:
The answer is 32
Emily signed 2/5 so 75 divided by 5 is 15
15x2 is 30
75-30=45
45 divided by 1/9 is 5
30+5=35
so then 45-5=40
20% of 40 is 8
30+5+8 = 43
75-43=32

Given trapezoid ABCD whose bases are segment AB and segment CD, what is mZB?
Answers
Answer:
x = 19
<B = 125°
Step-by-step explanation:
The sum f angle <D and angle <A is equal to 180° because these angles are supplementary
75° + 5x + 10 = 180° add like terms
85 + 5x = 180 subtract 85 from both sides
5x = 95 divide both sides by 5
x = 19
Same rule goes for angle <C and angle <B
<B + 55° = 180 subtract 55 from both sides
<B = 125°
