Answer:

Step-by-step explanation:

Substitute 3x into y=-4x-49

y=−4x−49

3x=−4x−49

3x+4x=−4x−49+4x(Add 4x to both sides)

7x/7=−49/7

(Divide both sides by 7)

x=−7

Step: Substitute−7forxiny=3x:

y=3x

y=(3)(−7)

y=−21(Simplify both sides of the equation)

Answer:

x=−7 and y=−21

The solution set to the given system of equation is (- 7, - 21).

Given are the system of equations as follows -

y = 3x

y = - 4x - 49

We have the equations as -

y = 3x             .... Eq [1]

y = - 4x - 49     .... Eq [2]

Now, we can write the equation [2] as -

3x = - 4x - 49

7x = -49

x = - 7

So, we can find the value of [y] as -

y = 3x

y = 3 x - 7

y = - 21

Therefore, the solution set to the given system of equation is (- 7, - 21).

Divide all 3 terms by 3:

-2<x<4

Answer:

112 is the answer

Step-by-step explanation:

to find the value of x, you need to add both the numbers 34 and 78 to find x.

Answer:

x=112

Step-by-step explanation:

x=78+34

(here the 34 passes to the other side, and because it is substracing, you pass it adding)

Answer:

The answer to the question provided is 16 units.

.

Step-by-step explanation:

☆Well, we simply use the distance formula, which is:

[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} }[/tex]

...

☆All we need to do is plug in!

[tex]d = \sqrt{(x_2 - x_1)^{2} + (y_2 - y_1)^{2} } \\ \\ d = \sqrt{(9 - 25) {}^{2} + (12 - 12)^{2} } \\ d = \sqrt{( - 16)^{2} + (0) ^{2} } \\ d = \sqrt{256 + 0} \\ d = \sqrt{ 256 } \\ d = 16[/tex]

Answer:

y = (x - 1)²

Step-by-step explanation:

A parabola is the locus of a point such that its distance from a fixed point (known as the focus) and a fixed line (known as the directrix) is always constant. The equation of a parabola is a quadratic equation.

The equation of a parabola with a horizontal directrix is given by:

(x - h)² = 4p(y - k).

Where the directrix (y) = k - p, vertex = (h, k)

Given that:  Vertex (1,0) and the Directrix y = -¼, Therefore:

vertex = (h, k) = (1, 0). h = 1 and k = 0.

y = k - p

but y = -1/4. Hence:

-1/4 = k - p

p = k + 1/4

p = 0 + 1/4

p = 1/4

Since the equation of the parabola is:

(x - h)² = 4p(y - k).

Substituting:

(x - 1)² = 4(1/4)(y - 0)

(x - 1)² = y

y = (x - 1)²

y = x² - 2x + 1

Answer:

the trip would be 800 miles all together

Step-by-step explanation:

if you divide 240/3 it is 80 which means that 80 miles is 10% of the trip so you can multiply 80 by 10 to see that 800 miles is 100% of the trip.

Answer:

$40

Step-by-step explanation:

22/55 = dollar per percent

dollar per percent = 0.4

0.4 x 100 will equal to 100% of the original price

0.4 x 100 = 40

to check, 40 x 55% = 22

Answer:

the correct answer is C. 75°

The value of ∠R = 75⁰

The measurements of the sides and angles of two or more triangles determine whether they are congruent. A triangle's size is determined by its three sides, and its shape is determined by its three angles. If the pairs of their corresponding sides and angles are equal, two triangles are said to be congruent.

Given ΔQRS ≅ ΔXYZ

for congruency the sides and angle of both the triangles should be equal so for  ΔQRS and ΔXYZ ; QR = XY, QS = XZ, and RS = YZ and

∠Q = ∠X, ∠S = ∠Z and ∠R = ∠Y

from figure ∠Q = ∠X = 55⁰, ∠S = ∠Z  = 50⁰

sum of angle of triangle is 180⁰,

∠Q + ∠S + ∠R = 180⁰

∠R  = 180 - 55 - 50

∠R  = 75⁰

Hence ∠R  = 75⁰

Answer:

y = -3x + 8.3

Step-by-step explanation:

You need to rearrange 9x + 3y = 22 in the form y = mx +c.

9x+3y = 22

3y = -9x +22

y = -3x + 7.3

As long as the gradient is the same, the lines will be parallel. So you can give any number to the intercept (in this case I gave 8.3) and you will have parallel equations.

r = 5.8 cm r = 7.1 cm

d = 11.6 cm d = 14.2 cm

C = 36.44 cm C = 44.611 cm

A = 105.68 cm2 A = 158.37 cm2

Answer:

the 3rd and 5th one

Step-by-step explanation:

Answer: Plus or minus 1 standard deviation from the mean.

Step-by-step explanation:

According to the Empirical rule,

If the population is normally distributed then, about 68% of the population lies within 1 standard deviation from the mean value.

Here, the data shows 68% percent of the area under the normal  distribution.

This is equivalent to "plus or minus 1 standard deviation from the mean."

Hence, the correct option is : plus or minus 1 standard deviation from the mean.
