which function has a y-intercept of 3
Answers
Answer:
2 and 3
1 also has a y-intercept of 3, but it is negative, so I don't know if that one will count
Step-by-step explanation:
Substitute X for 0 and solve from there.
3(0) - 2y = -6
0 - 2y = -6
y = 3
y - 3 = -2(0)
y - 3 = 0
y = 3

What value of x makes this equation true?
X/6 - 7 = -4
Answers
Answer:
[tex]x = 18[/tex]
Step-by-step explanation:
Given
[tex]\frac{x}{6} - 7 = -4[/tex]
Required
Solve for x
[tex]\frac{x}{6} - 7 = -4[/tex]
Add 7 to both sides
[tex]\frac{x}{6} - 7+7 = -4+7[/tex]
[tex]\frac{x}{6} = -4+7[/tex]
[tex]\frac{x}{6} = 3[/tex]
Multiply through by 6
[tex]6 * \frac{x}{6} = 3 * 6[/tex]
[tex]x = 3 * 6[/tex]
[tex]x = 18[/tex]

Step-by-step explanation:
The value of x from the given similar triangles is 7 units.
What are similar triangles?Two triangles are similar if the angles are the same size or the corresponding sides are in the same ratio. Either of these conditions will prove two triangles are similar.
The given triangles ABC and DEF are similar triangles.
Here, AB/DE =AC/DF =BC/EF
4/12 =8/3(x+1)
8/3(x+1) =1/3

what is 100 x 1000? And Explain your reasoning for the brainliest.
Answers
Answer:
100000
Step-by-step explanation:
100,000 or one hundred thousand.
1000 = one thousand
If you have 100 one thousands then you will have one hundred thousand.
aka 100,000
so 100 x 1000 = 100,000
One hundred times one thousand equals one hundred thousand.

Find the slope intercept equation of the line
PLEASE HELP ME!!!!!
Answers
Answer:
y = -x + 6Step-by-step explanation:
Slope-intercept form:
y = mx + b, where m is slope and b is y-interceptWe see on the graph y-intercept is b = 6, point (0.6)
To find the slope we need a second point, choosing point (5, 1)
Using slope formula:
m = (1- 6)/(5 - 0) = -5/5 = -1So the line is:
y = -x + 6Answer:
y = -4/5x + 5
Step-by-step explanation:
the formula for slope intercept is y=mx+b.
m represents the slope of the line and b is the y intercept. all you have to do is replace those variables.
the y intercept is the point where the line crosses the y-axis (the line going up and down on the graph). (0,5) is the y intercept and so 5 would replace b in y=mx+b
so far we have y=mx+5
The slope is the vertical change between two points is called the rise, and the horizontal change is called the run. Starting from a point on the line you would move vertically until you're in line with another point. In this case, let's just use (0,5) from before. You would go up four to line up with a point. Then, move horizontally to meet up with the point and count the units, which is five here. And so, the slope would be 4/5.
And then you get the equation:
y=4/5x+b
State whether the triangles are similar. If they are, write a similarity statement and the postulate or theorem you used.
Given: m∠R = 29° and m∠T = 29°
Answers
Answer: Correct option: B. ΔQRS ≈ ΔUTV, SAS
Step-by-step explanation:
IN the given triangles (ΔQRS and ΔUTV),
m∠R = 29° and m∠T = 29° (given)
[tex]\dfrac{QR}{UT}=\dfrac{16}{8}=2\\\\\dfrac{SR}{VT}=\dfrac{64}{32}=2\\\\\therefore\dfrac{QR}{UT}=\dfrac{SR}{VT}[/tex]
By SAS similarity rule , ΔQRS ≈ ΔUTV .

Solve this inequality for x.
Answers
______________________________
1.) Multiply both sides of the equation by 5:[tex]81[/tex] × [tex]5=405[/tex][tex]55[/tex] × [tex]5=275[/tex]- Since 5 is positive, the inequality direction remains the same.
Inequality at the end of Step 1:
[tex]405-(1[/tex] × [tex]5+1)[/tex] ≤ [tex]275[/tex]2.) Solve the parenthesis:Multiply 1 and 5 to get 5.Add 5 and 1 to get 6.- We turn the fraction into parenthesis by multiplying because a fraction is originally is dividing, so we have to do the opposite, which in this case is multiplying.
Inequality at the end of Step 2:
[tex]405-6x[/tex] ≤ [tex]275[/tex]3.) Subtract 405 from both sides:[tex]405-405=[/tex] Cancels Out[tex]275-405=-130[/tex]- We do this to get 1 number/variable on each side.
Inequality at the end of Step 3:
[tex]-6x[/tex] ≤ [tex]-130[/tex]4.) Divide both sides by −6:[tex]-6x[/tex] ÷ [tex]-6=x[/tex][tex]-130[/tex] ÷ [tex]-6=\frac{-130}{-6}[/tex]- Since −6 is negative, the inequality direction is changed.
Inequality at the end of Step 3:
[tex]x[/tex] ≥ [tex]\frac{-130}{-6}[/tex]5.) Reduce the fraction [tex]\bold{\frac{-130}{-6}}[/tex] to lowest terms by extracting and canceling out −2:[tex]-130[/tex] ÷ [tex]-2=65[/tex][tex]-6[/tex] ÷ [tex]3[/tex]- Extracting and cancelling out just means dividing. So we just divide the numerator and denominator by -2.
Inequality at the end of Step 5:
[tex]x[/tex] ≥ [tex]\frac{65}{3}[/tex]6.) Turn the fraction into a mixed number:[tex]\frac{65}{3}=21\frac{2}{3}[/tex]- You can figure this out by dividing 65 by 3 which gives you a decimal, then turn the decimal into a fraction.
