Find the x and y intercepts of -7x-5y=35
Answer: x-intercept: y = -7
y-intercept: x = -5
Step-by-step explanation:
Rearrange to standard format: y=mx+b
-7x-5y=35
-5y= +7x + 35
y= -(7/5)x -7
b is the y-intercept b=-7
--
Find a value for x that makes y = 0, the x-intercept.
y= -(7/5)x -7
0= -(7/5)x -7
(7/5)x = -7
(5/7)*(7/5)x = (5/7)*(-7)
x = -5, the y-intercept

there are 25 students in class 2-11 and 20% wear glasses. How many wear glasses?
Answer:
Five students wear glasses.
Step-by-step explanation:
20 percent of 25 is 5
We are given that 25 students in the class and 20% wear glasses.
Take 20% of 25 to calculate how many students wear glasses.

Find the slope of the line that passes through the points (9, -2) and (-3. -2). Write the equation in
slope-intercept form.
Answer:
slope: zero/none
equation: y = -2
Step by Step:
1) find the slope - change in y / change in x
-2+2/9+3
0/12
0 <- zero slope = no slope
2) plug in and solve for y-intercept
( -3, -2 )
-2=(0*-3)+b
b=-2
because the slope was zero, we know that it's a horizontal line
therefore the only equation we can get from this is a y= equation
3) plug in values to get equation
y = -2
slope is zero

Stephen was thinking of a number. Stephen divides by 5 then adds 1 to get an answer of 21. Form an equation with
x
from the information.
Answer:
x/5 +1 = 21
Step-by-step explanation:
x is your variable. first step is divided by 5, so you put x/5. then it says add 1 so simply add it on to the equation x/5 + 1. the entire equation equals to 21 so you put the equal sign after x/5 +1 =21

Solve:
3x-5/2 +x+ 2x-3/3 = 5/6 - 3x/2
Answer:
x = 26/45
Step-by-step explanation:
Answer:
Given Question
Solve for x :
[tex]\rm :\longmapsto\:\dfrac{3x - 5}{2} + x + \dfrac{2x - 3}{3} = \dfrac{5}{6} - \dfrac{3x}{2} [/tex]
[tex] \green{\large\underline{\sf{Solution-}}}[/tex]
Given expression is
[tex]\rm :\longmapsto\:\dfrac{3x - 5}{2} + x + \dfrac{2x - 3}{3} = \dfrac{5}{6} - \dfrac{3x}{2} [/tex]
On taking LCM of (2 and 3 = 6) on LHS and Taking LCM of ( 2 and 6 = 6) on RHS, we get[tex]\rm :\longmapsto\:\dfrac{3(3x - 5) + 6x + 2(2x - 3)}{6} = \dfrac{5 - 9x}{6}[/tex]
[tex]\rm :\longmapsto\:9x - 15 + 6x + 4x - 6 = 5 - 9x[/tex]
[tex]\rm :\longmapsto\:(9x + 6x + 4x) - 15 - 6 = 5 - 9x[/tex]
[tex]\rm :\longmapsto\:19x - 21 = 5 - 9x[/tex]
[tex]\rm :\longmapsto\:19x + 9x = 5 + 21[/tex]
[tex]\rm :\longmapsto\:28x = 26[/tex]
[tex]\rm :\longmapsto\:x = \dfrac{26}{28} [/tex]
[tex]\bf\implies \:x = \dfrac{13}{14} [/tex]
VERIFICATIONConsider LHS
[tex]\rm :\longmapsto\:\dfrac{3x - 5}{2} + x + \dfrac{2x - 3}{3}[/tex]
On substituting the value of x, we get
[tex]\rm \: = \: \dfrac{\dfrac{39}{14} - 5}{2} + \dfrac{13}{14} + \dfrac{\dfrac{13}{7} - 3}{3}[/tex]
[tex]\rm \: = \: \dfrac{39- 70}{28} + \dfrac{13}{14} + \dfrac{13 - 21}{21}[/tex]
[tex]\rm \: = \: \dfrac{ - 31}{28} + \dfrac{13}{14} - \dfrac{8}{21}[/tex]
[tex]\rm \: = \: \dfrac{ - 31 + 26}{28} - \dfrac{8}{21}[/tex]
[tex]\rm \: = \: \dfrac{ -5}{28} - \dfrac{8}{21}[/tex]
[tex]\rm \: = \: \dfrac{ -15 - 32}{84}[/tex]
[tex]\rm \: = \: - \: \dfrac{47}{84}[/tex]
Consider RHS
[tex]\rm :\longmapsto\: \dfrac{5}{6} - \dfrac{3x}{2} [/tex]
On substituting the value of x, we get
[tex] \rm \: = \: \dfrac{5}{6} - \dfrac{39}{28} [/tex]
[tex] \rm \: = \: \dfrac{70 - 117}{84}[/tex]
[tex] \rm \: = \: - \dfrac{47}{84}[/tex]
Hence, LHS = RHS
Hence, Verified.
Steven deposits $200 in a savings account, and decides to increase the amount by $5 every month. Identify the function that describes the arithmetic sequence, and the amount he should deposit after 8 months.
possible answer: D = 8n + 200; $240
possible answer: D = −5n + 200; $160
possible answer: D = 5n + 200; $240
possible answer: D = −8n + 200; $160
The required equation is D = 5n + 200 and the amount deposited after 8 months is $240
Given the amount that steven deposited every month as $200
Let n be the number of months
If he decides to increase the amount by $5 every month, then the amount added after n months will be $5nThe function that describes the arithmetic sequence will be expressed as sum of the amount deposited and increment:D = 200 + 5n = 5n + 200
In order to get the amount deposited after 8 months, we will replace n by 8 to have:
D = 200 + 5(n)
D = 200 + 5(8)
D = 200 + 40
D = 240
Hence the required equation is D = 5n + 200 and the amount deposited after 8 months is $240

Kylee is making a cake. The box says for every 1/4 cup of water she needs to use 2/4 of the cake mixture. She uses 3 1/4 cups of water. How much cake mixture does she use? (show your answer as a decimal and as a fraction.)
Answer:
Kylee makes 6 1/2, or 6.5 cups of the cake mixture.
Step-by-step explanation:
She uses double the cake mixture as water. She uses 3 1/4 cups of water, or 13/4 as an improper fraction, so she uses double that of cake mixture, which is 6 1/2, or 26/4 cups of cake mixture.
As a decimal that is 6.5.

The left and right page numbers of an open book are two consecutive integers whose sum is 23. Find these page number.
Answers: The page numbers are 11 and 12
==========================================================
Explanation:
Consecutive integers are ones that follow immediately after another. For example, the set {7,8,9,10} are consecutive.
Let,
x = first page, some positive whole numberx+1 = second page, follows immediately after page xAdding those two said pages will lead to 23
first + second = 23
(x) + (x+1) = 23
2x+1 = 23
2x = 23-1
2x = 22
x = 22/2
x = 11 is the first page
x+1 = 11+1 = 12 is the second page
Check: 11+12 = 23 which confirms the answers.

The answer is angle 4.
Step-by-step explanation:
Complimentary angles add up to 90°. So when it says what is the complimentary angle to angle 5, they want to know which angle will add up to 90° along with angle 5. We know that angles 1 and 3 are congruent and that angle 2 and angles 4+5 are congruent. Therefore angles 4 and 5 must add up to 90°.
