What is the equation of the line that passes through the point (- 4, 4) and has a slope of 3/4
Answer:
y = 3/4x + 7Step-by-step explanation:
Slope-intercept form:
y = mx + bGiven
m = 3/4 and point (-4, 4)Substitute values to find b:
4 = 3/4(-4) + b4 = -3 + b7 = bThen the line is:
y = 3/4x + 7
A flat rectangular piece of aluminum has a perimeter of 62 inches. The length is 15
inches longer than the width. Find the width.
Answer:
Width of rectangular piece = x = 8 inches
Step-by-step explanation:
Perimeter of rectangular piece = 62 inches
Let width of rectangular piece= x
and length of rectangular piece = x+15
We need to find width i.e value of x
The formula used for perimeter of rectangle is: [tex]Perimeter=2(Length+Width)\\[/tex]
Putting values in formula and finding Width:
[tex]Perimeter=2(Length+Width)\\\\62=2(x+x+15)\\62=2(2x+15)\\62=4x+30\\62-30=4x\\4x=32\\x=\frac{32}{4}\\x=8[/tex]
After solving we get value of x = 8
So, Width of rectangular piece = x = 8 inches
Expand and simplify (x + 3)(x + 5)
Step-by-step explanation:

Step-by-step explanation:
work out the value of x
Answer:
117 degrees
Step-by-step explanation:
So we already know that one angle is 38 degrees, so we have that one. The angle, 101 is exterior, and we have to subtract 180 from that to get the interior angle. We get a difference of 79. Since the sum of a triangle's interior angles are 180, we have to add 38+79 to get 117. Then, we have to subtract it from 180 to get the value of the interior angle as 63 degrees. Because x is on the outside, we have to again subtract 63 from 180 to get the missing value of x as 117.
180° - 101° = 79°
180° - (38° + 79°)
180° - 117° = 63°
180° - 63° = 117°
x = 117°

Felicity writes −2 2/5 as a fraction using the same method she knows for positive mixed numbers. Her work is shown: Multiply the whole number by the denominator: −2⋅5=−10. Add the numerator: −10+2=−8. Write this number over the original denominator: −2 2/5=−8/5. Does this method work to correctly write −2 2/5 as a fraction? Complete the statements below to answer the question.
Answer:
Step-by-step explanation:
2 2/5 = 12/5
-2 2/5= -12/5
To change a mixed number to an improper fraction, take the bottom number or denominator and times by the whole number and then add the top or numerator. So 5*2=10+2=12 put that on top of the denominator you already have or 5

Which equation represents the line that passes through points (1,-5) and (3, -17)?
y=-6x+1
Oy - 6x + 1
y=-6x-1
O y=x-1
Need ASAP!!
Answer:
The equation y = -6x + 1 represents the line ⇒ A
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slopeb is the y-interceptThe rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points lie on the line∵ The line passes through points (1, -5) and (3, -17)
∴ x1 = 1 and y1 = -5
∴ x2 = 3 and y2 = -17
→ Substitute them in the rule of the slope to find it
∵ m = [tex]\frac{-17--5}{3-1}[/tex] = [tex]\frac{-17+5}{2}[/tex] = [tex]\frac{-12}{2}[/tex] = -6
∴ m = -6
→ Substitute it in the form of the equation above
∴ y = -6x + b
→ To find b substitute x by 1 and y by -5 in the equation
∵ -5 = -6(1) + b
∴ -5 = -6 + b
→ Add 6 to both sides
∴ 1 = b
→ Substitute it in the equation
∴ y = -6x + 1
∴ The equation y = -6x + 1 represents the line

What is the length of DB?
A. 5
B. 12
C. 19
D. 25
Answer:
Length of DB = 19 (Approx)
Step-by-step explanation:
Given:
AC=7
AD=6
BC=18
Find:

19 ≥ DB
Length of DB = 19 (Approx)
how do you determine the quadratic equation having roots that are real numbers and equal
Answer:
To determine the nature of roots of quadratic equations (in the form ax^2 + bx +c=0) , we need to calculate the discriminant, which is b^2 - 4 a c. When discriminant is greater than zero, the roots are unequal and real. When discriminant is equal to zero, the roots are equal and real.
ANSWER:
when the value of (b^2-4ac) is positive, then the roots are real and distinct.
when it is 0 the roots are equal and if it is negative than its root is not real.

Use the information to answer the following question.
The angle measures of a triangle are shown.
Angle A: (5x – 5) degrees
Angle B: (3x + 3) degrees
Angle C: (5x) degrees
The sum of the measures of the three angles is equal to
180
°. What is the measure of Angle B? Explain
Answer:
Angle A
Step-by-step explanation:
subtract 3x and 5x
you get 2x
-5-3=
you get -8
divide -8/2x
x=-4
♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️♥️
Sum of the measures is equal to 180° .
So :
[tex]Angle \: \: A + Angle \: \: B + Angle \: \: C = 180 \\ [/tex]
Thus :
[tex](5x - 5) + (3 x + 3) + (5x) = 180 \\ [/tex]
Collect like terms
[tex]13x - 2 = 180[/tex]
Add sides 2
[tex]13x - 2 + 2 = 180 + 2[/tex]
[tex]13x = 182[/tex]
Divide sides by 13
[tex] \frac{13x}{13} = \frac{182}{13} \\ [/tex]
[tex]x = 14[/tex]
_________________________________
[tex]Angle \: \: B = 3x + 3[/tex]
[tex]Angle \: \: B = 3(14) + 3[/tex]
[tex]Angle \: \: B = 42 + 3[/tex]
[tex] Angle \: \: B = 45°[/tex]

Dr. Betz, a vet, is running a free rabies clinic. He estimates that it will take him 12 minutes for each animal he treats. Dr. Betz has already seen 20 animals, the last of which was a shaggy dog. Write an equation for how many minutes Dr. Betz worked. How long did Dr. Betz work at the rabies clinic if he saw 20 more animals after the shaggy dog?
Answer:
equation: y = 12x
Dr. Betz worked for 8 hours.
Step-by-step explanation:
To write the equation we'll use the form y = mx, where y represents the amount of time the Doctor worked, m is the amount of minutes it takes to treat each animal, and x is how many animals have been treated. We know the value of m is 12, so let's put that into the equation:
y = 12x
Now we have our equation. We can use it to see how long Dr. Betz worked. He treated a total of 40 animals - 20 including the shaggy dog, and 20 after the shaggy dog. let's replace x with 40:
y = 12(40)
Now solve:
y = 480
Dr. Betz worked for 480 minutes. There are 60 minutes in an hour. Divide 480 by 60 to find out how many hours Dr. Betz worked for:
480/60 = 8
Dr. Betz worked for 8 hours.
Is 30.030 greater than, less than, or equal to 30.03
Answer:
equal
Step-by-step explanation:
Answer:
equal
Step-by-step explanation:
30.030 can be simplified to 30.03. the zero after the .03 is unnecessary. since 30.030 can be written as 30.03, 30.030 is equal to 30.03
