11) slope and y-intercept, if the answer ignore this if you do know the answer than plz answer
Answer:
Slope : -1
Y-intercept : (0,6)
Step-by-step explanation:
Answer:
Slope: -1
y-intercept: 6
Step-by-step explanation:
Lets figure out the slope with the formula, [tex]\frac{y2 - y1}{x2-x1}[/tex]. Take 2 coordinates and substitute them in. Lets take (-3,9) and (-1,7). Here are the steps:
[tex]\frac{7-9}{-1-(-3)}[/tex]
[tex]\frac{-2}{-1+3}[/tex]
[tex]\frac{-2}{2}[/tex]
[tex]-1[/tex]
Now we know that the slope is -1, so m = -1.
Lets figure out the y-intercept. We have to have an equation with the slope in it. Since we don't know the y-intercept yet, we will use the equation y = -x + b. Lets take the coordinate (5,1). Substitute the coordinates in. Here are the steps:
1 = -5 + b
b = 6
Now we know that the y-intercept is 6, so b = 6. I hope this helped!

16.65 divided by 0.37
i need halp wit this and also i brainly keeps deleting meh questions
Answer:
45
Step-by-step explanation:
The equivalent problem is 16.65×10²/0.37×10² and the quotient is 45.
What is a quotient?In arithmetic, a quotient is a quantity produced by the division of two numbers. The quotient has widespread use throughout mathematics, and is commonly referred to as the integer part of a division, or as a fraction or a ratio.
Given that, 16.65 divided by 0.37.
Now, multiply both numerator and denominator by 10², we get
16.65×10²/0.37×10²
= 1665/37
= 45
Therefore, the quotient is 45.

Yolanda has read 10 pages of her novel and reads 0.5 pages each minute. Jasmin has read 15 pages of the same novel and reads 0.25 pages per minute. After how many minutes will Yolanda have read at least the same number of pages as jasmine?
Unit rate is the quantity of an amount of something at a rate of one of another quantity.
10 pages = 20 minutes
15 pages = 15 x 20/10 minutes
15 pages = 30 minutes
The number of minutes at which Yolanda will have read the same number of pages as Jasmine is 30 minutes.
What is a unit rate?It is the quantity of an amount of something at a rate of one of another quantity.
In 2 hours, a man can walk for 6 miles
In 1 hour, a man will walk for 3 miles.
We have,
Yolanda:
0.5 pages = 1 minute
Multiply 10/0.5 on both sides.
10 pages = 10/0.5 x 1 minute
10 pages = 20 minutes
Jasmin:
0.25 page = 1 minute
1 page = 4 minutes
15 pages = 60 minutes
Now,
The time at which Yolanda will read 15 pages
10 pages = 20 minutes
15 pages = 15 x 20/10 minutes
15 pages = 30 minutes
Thus,
The number of minutes at which Yolanda will have read the same number of pages as Jasmine is 30 minutes.

Solve the inequality.
3≤7+g
Answer:
g-4
Step-by-step explanation:
first subtract 7 from both sides
then you will get -4[tex]\leq[/tex]g
which is the same as g[tex]\geq[/tex]-4
you just have to switch them
The solution to the equation for inequality 3≤7+g is g ≥ -4. Equations and inequalities are both mathematical sentences that are formed by connecting two expressions.
How to solve the inequality ?Equations and inequalities are both mathematical sentences that are formed by connecting two expressions. The symbol = indicates that the two expressions in an equation are deemed equal. In contrast, in an inequality, the two expressions are not always equal, as indicated by the symbols: >,, or.
You test the end point by plugging it into the related equation. The inequality is then tested to see if it is correct by substituting any other solution to see if it is one of the solutions.
Rearrange the equation by subtracting what is to the right of the less equal sign from both sides of the inequality :
3-(7+g)≤0
Pull out like factors :
-4 - g = -1 • (g + 4)
Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
g+4 ≥ 0
Subtract 4 from both sides
g ≥ -4
The solution to the equation for inequality is g ≥ -4.

9. Evaluate the ceiling function for the given value.
A. f(x) = ⌈x⌉; x = −7.4
B. g(x) = ceiling (x, 0.50);
x = 21.27
Given:
A. f(x) = ⌈x⌉; x = −7.4
B. g(x) = ceiling (x, 0.50); x = 21.27
To find:
The values of ceiling function for the given value.
Solution:
A.
We have,
f(x) = ⌈x⌉; x = −7.4
Here, f(x) is a ceiling function, so we need to find the nearest next integer value because if m < x ≤ n, then ⌈x⌉ = n, where m and n are integers.
Now,
f(-7.4) = ⌈-7.4⌉
f(-7.4) = -7
Therefore, the value of f(x) is -7 at x=-7.4.
B.
g(x) = ceiling (x, 0.50); x = 21.27
Here, g(x) is a ceiling function with 0.50, so we need to find the nearest next multiple of 0.50 because if m < x ≤ n, then ⌈x⌉ = n, where, m and n are multiples of 0.50.
Now,
g(21.27) = ceiling (21.27, 0.50)
g(21.27) = 21.50
Therefore, the value of g(x) is 21.50 at x=21.27.
