Please help ASAP thank you
Answer:
A) a = 25
B) b = 14
Step-by-step explanation:
hopefully this helps :)
Solve the following:
[tex] \\ \sf \: a) \: \: \frac{a}{5} + 3 = 8[/tex]
[tex] \\ \sf \: b) \: \: \frac{3b}{7} - 1 = 5[/tex]
Solution:-Solving question a) :
[tex] \\ \sf \frac{a}{5 } + 3 = 8[/tex]
[tex] \\ \sf \mapsto \frac{a + 15}{5} = 8[/tex]
[tex] \\ \sf \mapsto \: a + 15 = 8 \times 5[/tex]
[tex] \\ \sf \mapsto \: a = 40 - 15[/tex]
[tex] \\ \sf \mapsto \: a = 25[/tex]
[tex] \\ \sf \therefore \: a = 25[/tex]
Solving question b) :
[tex] \\ \sf \frac{3b}{7} - 1 = 5[/tex]
[tex] \\ \sf \mapsto \: \frac{3b - 7}{7} = 5 [/tex]
[tex] \\ \sf \mapsto3b - 7 = 5 \times 7[/tex]
[tex] \\ \sf \mapsto3b = 35 + 7[/tex]
[tex] \\ \sf \mapsto \: b = \frac{42}{3} [/tex]
[tex] \\ \sf \mapsto \: b = 14[/tex]
[tex] \\ \sf \therefore \: b = 14[/tex]
Answer:-a = 25
b = 14
the quadratic x2-4x-21 can be witten in the form (x+a)2 +b find the values of a and b
(x-2)^2-25
How?
[tex]\\ \sf\longmapsto (x-2)^2-25[/tex]
[tex]\\ \sf\longmapsto x^2-4x+4-25[/tex]
[tex]\\ \sf\longmapsto x^2-4x-21[/tex]
Answer:
a = - 2, b = -25Step-by-step explanation:
Given quadratic expression:
x² - 4x - 21Convert this into vertex form:
x² - 4x + 4 - 25 = (x - 2)² - 25Compare this with the vertex form to determine the values of a and b:
a = - 2b = -25Can you y’all help me with this. i need to know what is the domain and range from this graph. i’m kinda confused for this
Answer:
The answer is below:
Step-by-step explanation:
The range is everything under and including 6 as we see that it will forever go to numbers under or equal to 6.
The range is all real because the lines will keep on going to infinity and negative infinity
Domain: All Real
Range: y is greater than or equal to 6

Amanda recorded the temperatures at which two oils freeze:
Oil Temperature
Olive oil −6.1 °C
Peanut oil 3.1 °C
Which statement about the temperatures at which these oils freeze is true?
A Peanut oil freezes at a lower temperature than olive oil because 3.1 °C < −6.1 °C.
B Peanut oil freezes at a higher temperature than olive oil because 3.1 °C < −6.1 °C.
C Peanut oil freezes at a lower temperature than olive oil because 3.1 °C > −6.1 °C.
D Peanut oil freezes at a higher temperature than olive oil because 3.1 °C > −6.1 °C.
Answer:
It's C, Peanut oil freezes at a lower temperature than olive oil because 3.1 > -6.1

Answer:
1/2 = 0.5 and 3/4 = 0.75
Use a proportion: 0.5/2.60 = 0.75/x
Cross multiply: 0.5x = 0.75*2.60
So x = 0.75*2.60/0.5 = 3.90
Which equation matches the graph of the greatest integer function given
below?
Answer:
D. y = [x] - 2
Explanation:
The Greatest Integer Function is denoted by y = [x].
For all real numbers, x, the greatest integer function returns the largest integer less than or equal to x. In essence, it rounds down a real number to the nearest lowest integer.
In the plot of y = [x], the plot starts from origin because y = [0] = 0.
But, in the question, all the lines are shifted 2 units downward, as it starts from (0, -2).
i.e for every values of x, y moves two units down
So our answer is y = [x] - 2.

Hope this helps, good luck! :D
[ SIDE NOTE: Someone else said that it is y=[x]-4, so I am not 100% sure! ]

Answer:
5 five dollar and 7 one dollar
Step-by-step explanation:
let the number of one dollar be xthe number of five dollar be y1x+5y=32
x+y=12
using elimination method
+x-x-y+5y-32+12=0
4y-20=0
4y=20
divide both side by 4y=20/4 =5
so, if. y is 5 then x is
5y+x=32
5(5)+x=32
25+x=32
x=32-25
x=7

On a field trip, the ration of students who brought a water bottle to those who didn’t was 7 to 4. If 60 students did not bring water bottle, determine the total number of students on the field trip.
Answer:
165 students
Step-by-step explanation:
7/4 = x/60
(60*7)/4 = 105
105 + 60 = 165

A 2-gallon bucket of paint costs $62.08. What is the price per cup?
Can Defects A company that makes soda pop cans finds that the
probability of producing a can without a puncture is 0.96, the probability that
a can does not have a smashed edge is 0.93, and the probability that a can
does not have a puncture and does not have a smashed edge is 0.893.
(a) Are the events "selecting a can without a puncture" and "selecting a can
without a smashed edge" mutually exclusive? Explain.
(b) If a quality inspector randomly selects a can, find the probability that the
can does not have a puncture or does not have a smashed edge
Using probability concepts, it is found that:
a) Since [tex]P(A)P(B) \neq 0[/tex], the events are not mutually exclusive.
b) 0.997 = 99.7% probability that the can does not have a puncture or does not have a smashed edge.
Item a:
Two events, A and B, are mutually exclusive if:
[tex]P(A \cap B) = 0[/tex]
In this problem:
Event A: No puncture, thus, [tex]P(A) = 0.96[/tex].Event B: No smashed edges, thus [tex]P(B) = 0.93[/tex]The problem also states that the probability of neither is [tex]P(A \cap B) = 0.893[/tex].
Since [tex]P(A)P(B) \neq 0[/tex], the events are not mutually exclusive.
Item b:
Using Venn probabilities, the "or" probability is given by:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
With the given values:
[tex]P(A \cup B) = 0.96 + 0.93 - 0.893 = 0.997[/tex]
0.997 = 99.7% probability that the can does not have a puncture or does not have a smashed edge.

help asap plsssssssssssssssssssssssssss. Find the missing parts of each number line. Assume that the lines have been split into equal parts.
Answer:
16 for the first one. each segment is 4
40 for the second. each segment is 8
Answer:
0, 4, 8, 12, 16
8, 16, 24, 32, 40, 48
Step-by-step explanation:
The first number line has 6 parts. 24÷6=4. Each vertical line will increase by 4.
So starting at 0, the parts of the number line are:
0, 4, 8, 12, 16, 20, 24
The specific part being asked for is 0, 4, 8, 12, 16
The second number line has 8 parts. 64÷8=8. Each vertical line will increase by 8.
Starting at 0, the parts of the number line are:
0, 8, 16, 24, 32, 40, 48, 56, 64
The specific part being asked for is 8, 16, 24, 32, 40, 48
