Answer:

In the equation :

$2x^2+6x-5$

α + β = -b/a

= -6/2

= -3

αβ = c/a

= -5/2

Jon has to pay $7.50 admission for the skating rink and $1.50 per hour to rent rollerblades. Write an equation for the cost (y)

Nata [24]

Answer:

y = 7.50 + 1.50x

Step-by-step explanation:

The admission costs $7.50 and after x hours Jon has to pay $1.50*x. Then the cost y in dollars is

y = 7.50 + 1.50x where x is the number of hours.

Can anyone pls helppppp

dalvyx [7]

Hourly rate:
39(1.3r) = 541.80
(hours times hourly rate equals profit)

then solve
1.3r = 13.89
r = 10.69

the hourly rate is $10.69

to answer the bottom question, 390 + 117 = 507, but that’s not close to 541.80 so I have no idea what they’re asking there

1. Two triangles have the following congruence statement: ACGI = AMPR Name all 6 pairs of corresponding congruent parts. 1.

rodikova [14]

Answer:

$\angle C \cong \angle M$

$\angle G \cong \angle P$

$\angle I \cong \angle R$

$\overline{CG} \cong \overline{MP}$

$\overline{GI} \cong \overline{PR}$

$\overline{CI} \cong \overline{MR}$

Step-by-step explanation:

Given the congruence statement ∆CGI $\cong$ ∆MPR, it follows that the corresponding sides of both ∆s are equal, as well as the corresponding vertices or angles. It implies that ∆CGI and ∆MPR are of the same shape and size.

✅Thus, the 6 pairs of the corresponding congruent parts of ∆CGI and ∆MPR are:

$\angle C \cong \angle M$

$\angle G \cong \angle P$

$\angle I \cong \angle R$

$\overline{CG} \cong \overline{MP}$

$\overline{GI} \cong \overline{PR}$

$\overline{CI} \cong \overline{MR}$

If f(x) = 2x2 + 1, what is f(x) when x = 3? a.1 b.7 c.13 d.19

prohojiy [21]

<u>Answer:</u>

The value of f(x) = $2x^2 + 1$ when x=3 is 19, hence the correct option is ‘d’.

<u>Solution:</u>

A two degree polynomial equation is given in the question.

The equation is:

$F(x)=2 x^{2}+1$

We need <em>to find the value of f(x) when the value of x is 3. </em>

To solve a question like this we have to substitute the given value of x in the given equation and then simplify it.

Now let's substitute the value of x in the given equation.

$F(x)=2(3)^{2}+1$

First we square the number 3 and then multiply it with 2 and then add 1.

This is done because of the BODMAS rule, in which multiplication is given higher preference as compared to addition.

On solving the equation we get,

F(x)=2×9+1

F(x)=18+1

F(x)=19.

Therefore the value of f(x) when x=3 is 19.

Hence the correct option is ‘d’.

I need help with these.

sattari [20]

Answer:

See below.

Step-by-step explanation:

1.

5^2 + 12^2 = x^2

25 + 144 = x^2

169 = x^2

x = 13

2.

3^2 + x^2 = [sqrt(10)]^2

9 + x^2 = 10

x^2 = 1

x = 1

3.

1^2 + x^2 = 4^2

1 + x^2 = 16

x^2 = 15

x = sqrt(15)

4.

[sqrt(27)]^2 + x^2 = 6^2

27 + x^2 = 36

x^2 = 9

x = 3

5.

15/5 = c/sqrt(29)

5c = 15 * sqrt(29)

c = 3sqrt(29)

6.

26/13 = x/12

2 = x/12

x = 24
