Answer:
Answer
Step-by-step explanation:
y=-4x+22
x=(11/2,0)
y=(0,22)
y=3x+10
x=(-10/3,0)
y=(0,10)
Solve using substitution x = 3y + 1 2x + 4y = 12
Answer:
x = 4
y = 1
Step-by-step explanation:
x = 3y + 1 (Multiply everything by -2)
2x + 4y = 12 (Transfer 4y to the right of the = sign)
2x = -4y + 12
-2x = -6y - 2
0 = -10y + 10
-10 = -10y
y = 1
x = 3y + 1
x = 3(1) + 1
x = 3 + 1
x = 4

CAN SOMEONE HELP ME WITH THIS PLEASE?
Answer:
Y= 4 and X=2
Step-by-step explanation:
When you are trying to find the X or Y value for an equation, set the opposite value to zero. That means that if you are trying to find Y in 6x+3y=12, you would make the X zero. Since six is being multiplied by X and X now equals zero, your equation for finding the Y value is now 3y=12. Divide them both by three and you get Y=4. In order to find your X value you would do the same thing. Since you are trying to find X, set the Y value to zero. That makes your equation for finding the X value 6x=12. That is because, again, you set Y to zero, and three times zero is zero. 6x=12 equals X=2 because you divide both sides by 6.

Ste-by-step explanation:
Use the information provided to solve the word problem below. The cost of a school banquet is $65 + $11n, where n is the number of people attending. Which is the cost for 70 people? a. $147 b. $834 c. $835 d. $146 Please select the best answer from the choices provided A B C D
Answer:
$835 (Answer c)
Step-by-step explanation:
Write out the Cost function: C(n) = $65 + ($11/person)n
Then the total cost for 70 people would be C(70) = $65 + ($11/person)(70 people)
C(70) = $65 + $770 = $835 (Answer c)
if you subtract 12 from my number and multiply the difference by -6 the result is -90 what is my number
Answer:
n must be 27
Step-by-step explanation:
Let this number be x. Then -6(n - 12) = -90.
Dividing both sides by -6 yields n - 12 = 15.
Add 12 to both sides.
Then n must be 27.
Check: subtract 12 from 27; this yields 15. Now multiply this result by -6. The result is -90, which was expected.

In a right triangle one angle measure 28° more than the other acute angle. Use equations to solve for the measures of the two unknown angles.
Answer:
One acute angle is 31 degrees and the other acute angle is ( 31+28=) 59 degrees.
Step-by-step explanation:
In the right angled triangle one angle is always equal to 90 degrees.
Suppose <a= 90 degrees
< b= x degrees
< c= x+28 degrees
The sum of all the angles of the triangle are always equal to 180 degrees
therefore
<a+ <b+<c= 90 + x+ x+28 = 180
or
2x= 180- 28- 90
2x=62
x= 31 degrees
One acute angle is 31 degrees and the other acute angle is ( 31+28=) 59 degrees.
An acute angle is an angle which has less than 90 degrees in measurement .
Hence both angles of the right angle triangle are acute angles , 31 and 59 degrees.

Which equation is y = (x + 3)2 + (x + 4)2 rewritten in vertex form?
y = 2 (x + seven-halves) squared minus one-fourth
y = 2 (x + seven-halves) squared minus one-half
y = 2(x + 7)2 – 73
y = (x + 7)2 – 24
Answer:
y = 2 (x + seven-halves) squared minus one-fourth [y = [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex] ]
Step-by-step explanation:
We know that,
vertex form is y = a(x-h)² + k
vertex is (h, k)
Now,
Given that the equation is -
y = (x+3)² + (x+4)²
= x² + 3² + 2×3×x + x² + 4² + 2×4×x
= x² + 9 + 6x + x² + 16 + 8x
= 2x² + 14x + 25
= [tex]x^{2} + 7x + \frac{25}{2}[/tex]
= [tex]x^{2} + 7x + \frac{25}{2} + \frac{49}{4} - \frac{49}{4}[/tex]
= [tex](x + \frac{7}{2} )^{2} + \frac{25}{2} - \frac{49}{4}[/tex]
= [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex]
∴ we get
The vertex form is -
y = [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex]
So,
The correct option is - y = 2 (x + seven-halves) squared minus one-fourth (y = [tex](x + \frac{7}{2} )^{2} - \frac{1}{4}[/tex] )
