Answer:

x=4

Step-by-step explanation:

y=2x-10 and 6x+7y=10

6x+7(2x-10)=10

6x+14x-70=10

20x=80

x=4

Answer:

4

Step-by-step explanation:

x²=16

x=√16

x=4

Answer:

x^2=16

^ stands for power or exponent

so, the equation is: x square= 16

for this x should be equal to 4

now,

4^2=16

Step-by-step explanation:

Answer:

Because you pay attention in school. Thank you for the points!!

Step-by-step explanation:

Answer:(0,0),(0,4) and (5,0)

Step-by-step explanation:

It is easy to find lengths of horizontal and vertical segments and distances from (0,0) so always place one vertex at the origin and one or more sides on an axis.

So this answer has a y intercept and an x intercept.

Answer:

a. 5

b. 1

c. 132

d. -2

Step-by-step explanation:

a. The square root of 4 is 2, the absolute value of -3 is 3. 2 + 3 = 5

b.  4 - (-3) / -7 = 7/ -7 = 1

c. 2 * 4^3 = 128 + (-3) - (-7) = 132

d. 2 (-7 + 3) = -8, square root to the third power of -8 is -2

I hope this helped, please mark Brainliest, thank you!!

Answer:

The answer is C - conjugation

Hope this helps!

Answer:

D

Step-by-step explanation:

A unit rate is basically which one increases more as time goes on. Now. to make it easier let me explain visual.

You have 50 apples at the start and every hour you get 200 more apples, sweet!

Now let's look at the chart.

The first one is 200x+100, this is wrong since this has a better start but you don't get as much apples.

Same goes for the B and C. The only one that would make sense is D since you're also adding 10 more apples for each one you increase.

Answer:

The given lines are parallel.

we already know that for parallel condition we apply;

m1=m2

1/2=0.5

0.5=0.5

Answer:

Area = 245m^2

Step-by-step explanation:

We can split this figure into 2 parts, a rectangle and a trapezoid.

Rectangle Sides = 10m and 20m

Area = 10m x 20m = 200m

Trapezoid formula = a+b/2(h)

a and b are the 2 bases and h is the height

Using a little deductive reasoning we get the following, 5+10/2(6)

This simplifies to 15/2(6) -->

7.5(6) = 45

Thus, our area is 200 + 45, or 245m^2

Answer:

The cost would be $3.28 for each gallon.

Answer:

Step-by-step explanation:

[tex]\left \{ {{xy=5} \atop {4+y=-x}} \right.\\\\<=> \left \{ {{xy=5} \atop {x=-4-y}} \right.\\\\=> \left \{ {{(-4-y)y=5} \atop {x=-4-y}} \right. \\\\<=> \left \{ {{-y^{2}-4y =5} \atop {x=-4-y}} \right. \\\\<=> \left \{ {{y^{2}+4y+5 =0} \atop {x=-4-y}} \right.[/tex]

because y² + 4y + 5 = (y+2)² + 1 > 0, ∀ y ∈ R

=> y² + 4y + 5 = 0 is unreasonable

=> no solutions

Answer:

465 miles

Step-by-step explanation:

D = r * t

D = 62 * 7.5 = 465 miles

Answer:

465

Step-by-step explanation:

We know that the rate is 62 mph. The time is 7.5 h.

Plug it into the existing equation:

D = r × t becomes D = 62 × 7.5

Just stick that into a calculator to get 465.

Answer:

Yes

Step-by-step explanation:

Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8. and that is something Very similar.

Answer:

Step-by-step explanation:

you start from 2 on the y axis and then go up 4 and right 3 so it will take you to coordinate point (6,3) then you start from 2 on the y axis again and go down 4 and left 3

Step-by-step explanation:

Answer:

Aproximately 25 days

Step-by-step explanation:

so he goes 15.12 mph and rides for 8 hours so 15.12*8=120.96

3069.25/120.69

=25.374091 round it to nearest whole number so its 25days

Answer:

Step-by-step explanation:

(17×25)×4=n×(25×4)

or 17×(25×4)=n×(25×4)  

17=n

∵ (a×b)×c=a×(b×c) [by associative law of multiplication.]

Given:

Height of box = (x-2)

Volume of box = [tex](x^3-8)[/tex]

To find:

The expression for the base area.

Solution:

We know that,

Volume of a box(V) = Base area(B) × Height(h)

[tex]V=Bh[/tex]

[tex]\dfrac{V}{h}=B[/tex]

On substituting the given values, we get

[tex]B=\dfrac{x^3-8}{x-2}[/tex]

[tex]B=\dfrac{x^3-2^3}{x-2}[/tex]

[tex]B=\dfrac{(x-2)(x^2+2x+2^2)}{x-2}[/tex]   [tex][\because a^3-b^3=(a-b)(a^2+ab+b^2)][/tex]

[tex]B=x^2+2x+4[/tex]

So, the base area is [tex]x^2+2x+4[/tex].

Therefore, the correct option is B.

Answer:

4% change

Step-by-step explanation:

Answer:

x < y > 2

Step-by-step explanation:

Girls is more than boys, so:

y > x

Girls is more than 2, so:

y > 2

So:

x < y > 2
