Step-by-step explanation:
To find the x-intercept, substitute in 0 for y and solve for x .To find the y-intercept, substitute in 0 for x and solve for y .
x-intercept(s): ( [tex]-\frac{5}{4}[/tex] , 0 )
y-intercept(s): ( 0 , − 15 )
Vertex: y = 4 ( x - [tex]\frac{7}{8}[/tex] )^2 [tex]\frac{289}{16}[/tex]

Answer:
6^6 = 6^2 x 6^4 = 46656
Step-by-step explanation:
6^16/6^2 = 78364164096 so doesn't equal 6^6
(6^2)^8 / 6^4 = 1679616 so doesn't equal 6^6
(6^4)^2 = 1679616 so doesn't equal 6^6
6^-1 x 6^9 = 1679616 so doesn't equal 6^6
6^-1 x 6^-8 = 9.92 so doesn't equal 6^6
By which rule are these triangles congruent? A. AAS B. ASA C. SAS D. SSS
A. AAS
Congruence means they are identical. From the markings, two angles are the same and one side is the same. So angle-angle-side.

Answer:
b. Complementary gas masks
Step-by-step explanation:
Adjacent means that the two angles are right next to each other and touching. The two angels in the photo are touching. Supplementary means that the two angels can for together to make a 180 degree line. The two angels in the photo make a 180 degree line. Complementary means that the two angels make a 90 degree angel. Since the two angels already make a 180 degree angels then, they cannot make a 90 degree angel. The question is asking for what it is not so, complements would be the answer.

(but i need the question)
(a) Write the point–slope form of a function that has a slope of 3- 5 and passes through the point (6,1).
(b) Algebraically manipulate your answer in part a to produce the slope– intercept form of the function that has a slope of 3 - 5 and passes through the point (6,1).
The question illustrates linear equation
The equation in point slope form is: [tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]The equation in slope intercept form is: [tex]\mathbf{ y = \frac 35x - \frac{13}5}[/tex]The given parameters are:
[tex]\mathbf{m = \frac 35}[/tex] --- the slope
[tex]\mathbf{(x_1,y_1) = (6,1)}[/tex] -- the point it passes through
(a) The equation in point slope form
This is represented as:
[tex]\mathbf{ y - y_1 = m(x - x_1)}[/tex]
Substitute known values
[tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]
So, the equation in point slope form is: [tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]
(a) The equation in slope intercept form
In (a), we have:
[tex]\mathbf{ y - 1 = \frac 35 (x - 6)}[/tex]
Open brackets
[tex]\mathbf{ y - 1 = \frac 35x - \frac{18}5}[/tex]
Add 1 to both sides
[tex]\mathbf{ y = \frac 35x - \frac{18}5 + 1}[/tex]
Take LCM
[tex]\mathbf{ y = \frac 35x + \frac{-18 + 5}5}[/tex]
[tex]\mathbf{ y = \frac 35x + \frac{-13}5}[/tex]
[tex]\mathbf{ y = \frac 35x - \frac{13}5}[/tex]
Hence, the equation in slope intercept form is: [tex]\mathbf{ y = \frac 35x - \frac{13}5}[/tex]

what are the x and y intercepts for the line: 4x-24=10 leave your answers in coordinate point form ( , ) ( , )
Answer:
(2.5, 0) and (0, - 5)Step-by-step explanation:
The line is:
4x - 2y = 10The x- intercept is the value of x, when y = 0:
4x - 2*0 = 104x = 10x = 2.5The y- intercept is the value of y, when x = 0:
4*0 - 2y = 10- 2y = 10y = - 5x intercept
4x-10=04x=10x=10/4x=5/2(2.5,0)

Round up or down 70 if rounding to the nearest 10
your answer is going to be 100 and how you do that is you're going to estimate which means you're taking an educated guess and is it 70 closer to zero or 100 70 is only 20 numbers away and how you find that is by subtracting 100 from 70 which equals 20 and how you do that to see if it's up or down is 50 is in your middle okay so it's going to go from 0 to 50 to 100 on a number line 70 is in between 50 and 100 so that means that you'll be going up now if you did 30 instead of 70 in your equation rounding by 10 then it would be in between the zero and the 50 which that means that you're going down

Answer:
48 units squared
Step-by-step explanation:
You can find the number of squares in each sector by multiplying by the width and height.
So we have 4 boxes that have 10 squares each giving us 40 squares for the 4 boxes plus the other 2 boxes that have 4 squares each.
4 * 10 + 2 * 4 = 48
We get 48 inches squared.

Answer:
Yes
Step-by-step explanation:
2x³-0x²+1x is similar to 2x³+1x
because if we simplify both equations we get...
2x³-0x²+1x simplified= 2x³+x
and...
2x³+1x simplified = 2x³+x
therefore we get the same answer for both

Answer:
3.75
Step-by-step explanation:
Angle 2 and angle 3 are supplementary angles, so we can add them together and put it equal to 180°
Equation:
30x + 14 + 10x + 16 = 180
Combine like terms:
40x + 30 = 180
Subtract 30 from both sides:
40x = 150
Divide both sides by 40:
3.75
Check:
Take the orginal equation:
30x + 14 + 10x + 16 = 180
Plug in for x:
30(3.75) + 14 + 10(3.75) + 16 = 180
Solve:
112.5 + 14 + 37.5 + 16 = 180
180 = 180 ✅

Find point slope form with 1/4 passing through (-7,-5)
Answer:
y+5 = 1/4(x+7)
Step-by-step explanation:
Point slope form is
(y-y1) = m(x-x1) where m is the slope and (x1,y1) is a point on the line
y- -5 = 1/4(x - -7)
y+5 = 1/4(x+7)
Hello There!
Point-Slope:
y-y₁=m(x-x₁)
y-(-5)=1/4(x-(-7)
y+5=1/4(x+7)
y=1/4x+1.75+5
y=1.4x+6.75
